Low birth weight and its associated factors in Ethiopia: a systematic review and meta-analysis

Does oral iron and folate supplementation during pregnancy protect against adverse birth outcomes and reduced neonatal and infant mortality in Africa: A protocol for a systematic review and meta-analysis?

BACKGROUND

Globally, one-third of pregnant women are at risk of iron deficiency, particularly in the African region. While recent findings show that iron and folate supplementation can lower the risk of adverse birth outcomes and childhood mortality, our understanding of its impact in Africa remains incomplete due to insufficient evidence. This protocol outlines the systematic review steps to investigate the impact of oral iron and folate supplementation during pregnancy on adverse birth outcomes, neonatal mortality and infant mortality in Africa.

METHODS AND ANALYSIS

MEDLINE, PsycINFO, Embase, Scopus, CINAHL, Web of Science, and Cochrane databases were searched for published articles. Google Scholar and Advanced Google Search were used for gray literature and nonindexed articles. Oral iron and/or folate supplementation during pregnancy is the primary exposure. The review will focus on adverse birth outcomes, neonatal mortality and infant mortality. Both Cochrane Effective Practice and Organization of Care and Newcastle-Ottawa Scale risk of bias assessment tools will be used. Meta-analysis will be conducted if design and data analysis methodologies permit. This systematic review and meta-analysis will provide up-to-date evidence about iron and folate supplementation's role in adverse birth outcomes, neonatal mortality and infant mortality in the African region.

ETHICS AND DISSEMINATION

This review will provide insights that help policymakers, program planners, researchers, and public health practitioners interested in working in the region.

The maternal factors associated with infant low birth weight: an umbrella review

BACKGROUND

In this umbrella review, we systematically evaluated the evidence from meta-analyses and systematic reviews of maternal factors associated with low birth weight.

METHODS

PubMed, Scopus, and Web of Science were searched to identify all relevant published studies up to August 2023. We included all meta-analysis studies (based on cohort, case-control, cross-sectional studies) that examined the association between maternal factors (15 risk factors) and risk of LBW, regardless of publication date. A random-effects meta-analysis was conducted to estimate the summary effect size along with the 95% confidence interval (CI), 95% prediction interval, and heterogeneity (I2) in all meta-analyses. Hedges' g was used as the effect size metric. The effects of small studies and excess significance biases were assessed using funnel plots and the Egger's test, respectively. The methodological quality of the included studies was assessed using the AMSTAR 2 tool.

RESULTS

We included 13 systematic Review with 15 meta-analysis studies in our study based on the inclusion criteria. The following 13 maternal factors were identified as risk factors for low birth weight: crack/cocaine (odds ratio [OR] 2.82, 95% confidence interval [CI] 2.26-3.52), infertility (OR 1.34, 95% CI 1.2-1.48), smoking (OR 2.00, 95% CI 1.76-2.28), periodontal disease (OR 2.41, 95% CI 1.67-3.47), depression (OR 1.84, 95% CI 1.34-2.53), anemia (OR 1.32, 95% CI 1.13-1.55), caffeine/coffee (OR 1.34, 95% CI 1.14-1.57), heavy physical workload (OR 1.87, 95% CI 1.00-3.47), lifting ≥ 11 kg (OR 1.59, 95% CI 1.02-2.48), underweight (OR 1.79, 95% CI 1.20-2.67), alcohol (OR 1.23, 95% CI 1.04-1.46), hypertension (OR 3.90, 95% CI 2.73-5.58), and hypothyroidism (OR 1.40, 95% CI 1.01-1.94). A significant negative association was also reported between antenatal care and low birth weight.

CONCLUSIONS

This umbrella review identified drug use (such as crack/cocaine), infertility, smoking, periodontal disease, depression, caffeine and anemia as risk factors for low birth weight in pregnant women. These findings suggest that pregnant women can reduce the risk of low birth weight by maintaining good oral health, eating a healthy diet, managing stress and mental health, and avoiding smoking and drug use.

Comparison of Baseline Characteristics, Sociodemographics, and Gynecological Risk Factors Associated with Secondary Infertility of Females in Pakistan

Introduction

Secondary infertility is characterized by the inability to conceive for a period of 1 year, after having previously conceived at least once.

Objectives

To explore the risk factors of secondary infertility and compare sociodemographics and anthropometric variables of each studied group.

Methods

Study was conducted at University Institute of Public Health, Faculty of Allied Health Sciences, The University of Lahore, collecting data from Gilani Ultrasound Center in 18 months after approval of synopsis. Total 690 females (345 cases and 345 controls) were enrolled. Participants were included in case group if they were 20-45 years of age, having any parity, and confirmed diagnosis of secondary infertility.

Results

The mean age of cases and controls was 33.08 ± 4.17 years and 31.37 ± 4.36 years, respectively. The mean body mass index (BMI) in cases was 27.61 ± 4.27 kg/m2, and in controls the mean BMI was 25.52 ± 4.30 kg/m2. There was not a significant difference among religion that shows no association (p = 0.73) with secondary infertility as profession has association with it (p = 0.01). History of polycystic ovary syndrome, pelvic inflammatory disease, endometriosis, uterine fibroids, menorrhagia, intermenstrual bleeding, and history of abortion are associated with secondary infertility.

Conclusions

While several sociodemographic features and medical disorders have been associated to secondary infertility, it is vital to stress that not all of these factors are controllable by medical therapy. Factors like age and certain medical issues may be unaffected by intervention. However, for controllable variables like BMI and certain medical diseases, focused therapies and lifestyle changes may reduce the chance of subsequent infertility.

Determinants of short birth interval among married multiparous women in Chinaksen district, eastern Ethiopia: a case-control study

Background

The short birth interval is a common public health issue that affects women's and children's health in sub-Saharan Africa. Despite a higher burden of short birth intervals reported in Ethiopia, there is limited evidence to indicate the primary risk factors, particularly in rural eastern Ethiopia. Therefore, this study assessed the determinants of the short birth interval among married multiparous women in Chinaksen district, Eastern Ethiopia.

Methods

A community-based case-control study was conducted among randomly selected 210 cases and 210 controls from April 01 to June 30, 2019. The total sample size (219 cases and 219 controls) were calculated using Epi-Info software version 7.2. Data were entered using EpiData version 3.1 and analyzed using SPSS version 27, and multivariable logistic regression analyses conducted to identify the determinants of short birth intervals. Adjusted odds ratio (AOR) with a 95% confidence interval (CI) was used to report the strength of association and statistical significance declared at p-value < 0.05.

Results

The women in the young age group (AOR = 2.33, 95% CI: 1.03, 5.26), missed their antenatal care visits (AOR = 2.23, 95% CI: 1.18, 4.21), failed to utilize postpartum contraceptives (AOR = 5.98, 95% CI: 3.62, 9.89), did not attend postnatal care visit (AOR = 1.86, 95% CI: 1.13, 3.05), nonexclusive breastfed (AOR = 4.05, 95% CI: 2.18, 7.52), short and medium period of breastfeeding (AOR = 4.00, 95% CI: 1.34, 12.10) and (AOR = 3.56, 95% CI: 1.62, 7.82), respectively and female sex of preceding child (AOR = 1.92, 95% CI: 1.18, 3.12) were the important risk factors of short birth interval.

Conclusions

Women's age, antenatal care visits, postnatal care attendance, utilization of postpartum contraceptives, exclusive breastfeeding practice, duration of breastfeeding, and sex of the preceding child were the primary predictors of short birth intervals. Improving the utilization of maternal healthcare services in health facilities would be imperative to prevent and reduce short birth intervals, and its negative consequences.

Magnitude of self-reported intimate partner violence against pregnant women in Ghana's northern region and its association with low birth weight

BACKGROUND

Low birth weight (LBW) rates are high in the northern region of Ghana, as is tolerance for intimate partner violence (IPV). However, the relationship between the two incidents has not been established. This study assessed the magnitude of IPV against pregnant women and its association with LBW in the northern region of Ghana.

METHODS

A cross-sectional study was conducted among 402 postnatal women from five public health care facilities in the Tamale Metropolitan Area, northern Ghana. Data were collected electronically during face-to-face interviews. Validated methods were used to determine IPV exposure during pregnancy and birth weight. Multivariable logistic regression was used to identify the independent association between prenatal exposure to IPV and LBW.

RESULTS

Of the 402 women, 46.5% (95% CI: 41.7, 51.4) experienced IPV during their most recent pregnancy. Of these, 34.8% were psychologically abused, 24.4% were sexually abused, and 6.7% were physically abused. Prenatal IPV exposure was found to be significantly associated with birth weight. Low birth weight was twice as likely among exposed women as among unexposed women (AOR = 2.42; 95% CI: 1.12, 5.26, p < 0.05). Low birth weight risk was also higher among women with anaemia in the first trimester (AOR = 3.47; 95% CI: 1.47, 8.23, p < 0.01), but was lower among women who made at least four antenatal care visits before delivery (AOR = 0.35; 95% CI: 0.14, 0.89, p < 0.05) and male newborns (AOR = 0.23; 95% CI: 0.11, 0.49, p < 0.001).

CONCLUSION AND RECOMMENDATION

IPV during pregnancy is prevalent in the research population, with psychological IPV being more widespread than other kinds. Women who suffered IPV during pregnancy were more likely to have LBW than those who did not. It is essential to incorporate questions about domestic violence into antenatal care protocols. In particular, every pregnant woman should be screened for IPV at least once during each trimester, and those who have experienced violence should be closely monitored for weight gain and foetal growth in the study setting to avert the LBW associated with IPV. In the northern region of Ghana, the number of babies born with low birth weight is high, as is the number of adults who are willing to put up with intimate partner violence. However, there has not been any proof that these two incidents are connected. This study looked at how frequently intimate partner violence occurs among pregnant women and how it is linked to low birth weight in northern Ghana's Tamale Metropolitan Area. A cross-sectional study was conducted with 402 postnatal women from five public health care facilities in the study setting. Information on exposure to intimate partner violence during pregnancy and the birth weight of babies was collected electronically during face-to-face interviews. The study found that of the 402 women, 46.5% had experienced violence by an intimate partner during their most recent pregnancy. Out of these, 34.8% were abused psychologically, 24.4% were abused sexually, and 6.7% were abused physically. Women who were abused were more likely than those who were not to have babies with low birth weight. We concluded that intimate partner violence is common during pregnancy in the study setting and that more women suffered psychological intimate partner violence than other types of violence. Intimate partner violence during pregnancy was linked to low birth weight in the study setting. It is important for antenatal care plans to include questions about intimate partner violence. In particular, every pregnant woman should be assessed for intimate partner violence at least once during each trimester for monitoring.

Magnitude and associated factors of low birth weight among term newborns delivered in Addis Ababa public hospitals, Ethiopia, 2021

Only 14% of births had information on birth weight available at the time of birth in Ethiopia. Hence, previous studies underestimate the magnitude and associated factors of low birth weight (LBW). As a result, the goal of this study is to fill those gaps in the previous studies. An institution-based cross-sectional study was employed. Binary logistic regression was used to identify the associated factors. In this study, the magnitude of LBW was 13.06%. History of chronic medical illness (AOR = 3; 95% CI: (1.02, 9.17)), haemoglobin level during pregnancy (AOR = 0.23; 95% CI: (0.10, 0.50)), iron/folic acid supplementation (AOR = 0.27; 95% CI: (0.10, 0.72)) and extra meal during pregnancy (AOR = 3.2; 95% CI: (1.52, 7.00)) were significantly associated with LBW. The magnitude of LBW in this study was comparable to the Ethiopian Demographic and Health Survey (EDHS) report from 2016. It is better to intervene in those identified factors in order to reduce LBW.Impact StatementWhat is already known on this subject? Low birth weight (LBW) accounts for 60-80% of all neonatal deaths each year. In developing countries like Ethiopia, LBW is a major public health concern. Almost half of the world's infants are not weighed at birth, a figure that is especially high in sub-Saharan Africa including Ethiopia.What do the results of this study add? Only 14% of births had information on birth weight available at the time of birth in Ethiopia. Hence, previous studies underestimate the magnitude and associated factors of LBW. To meet the Sustainable Development Goals (SDGs)-2030 targets for neonatal and child mortality, sufficient evidence on the magnitude of LBW and associated factors must be important in order to contribute to the development of timely interventions. A history of chronic medical illness, haemoglobin level, iron/folic acid supplementation and extra meal during pregnancy was associated with LBW.What are the implications of these findings for clinical practice and/or further research? The findings of this study will be useful in developing better health policies to prevent LBW as well as interventions that can target the identified factors.

A Comparative Cross-sectional Study on Prevalence of Low Birth Weight and its Anticipated Risk Factors

Objective. This study aims to highlight the low birth weight (LBW) in Taiz City (Yemen), as LBW is one of the public health challenges experiencing a profound effect on newborns. Methods. This was a cross-sectional study since the interview and medical records were the sources of data to be analyzed by SPSS. Results. The findings of this study include; a high prevalence of LBW (39.11%), the maternal age was not associated with LBW (P = .68), and education level, economic status, residence place, and health status were not associated with LBW (P < .05). Although the pre-pregnancy BMI, during-pregnancy BMI, MUAC, and gestational age were significantly associated with LBW (P < .05), the only risk factor was gestational age (OR = 9.606, CI = 3.988-23.135, P = .00). Conclusion. LBW is highly prevalent in Taiz (Yemen), so providing good healthcare services is essential to manage LBW incidence.

Determinants of acute undernutrition among pregnant women attending primary healthcare unit in Chinaksen District, Eastern Ethiopia: a case-control study

Background

Women's undernutrition during pregnancy increases the risks and burdens of maternal and neonatal morbidity, death, and disability through its vicious cycles of irreversible intergenerational negative effects. Despite the high burden of maternal undernutrition during pregnancy in semi-pastoral communities of eastern Ethiopia, there is a paucity of information on its major risk factors. This study revealed determinants of acute undernutrition among pregnant women attending primary healthcare units in Chinaksen district in rural eastern Ethiopia.

Method

A facility-based case-control study was conducted among 113 cases and 113 controls in Chinaksen district from February 01 to March 30, 2017. Data were entered using EpiData version 3.1 and analyzed using SPSS version 24. Multivariable logistic regression analyses conducted to identify significant determinants of acute undernutrition. Adjusted odds ratio (AOR) with a 95% confidence interval was used to report the strength of association and statistical significance declared at p value < 0.05.

Results

Sixty (53.1%) of cases and 56 (49.6%) of controls were in the age group of 25-34 years and their mean ± SD age of cases and controls were 26.6 ± 5.7 and 28 ± 5.5 years, respectively. In this study, larger family size (AOR = 6.98, 95 CI [2.82-17.27]), lack of prenatal dietary advice (AOR = 3.68, 95% CI [1.67-8.00]), did not participate in a cooking demonstration (AOR = 5.41, 95% CI [2.39-12.24]), used substances (AOR = 3.65, 95% CI [1.30-10.23]), absence of basic latrine (AOR = 2.91, 95% CI [1.28-6.58]), low minimum dietary diversity of women (AOR = 2.48, 95% CI [1.20-5.12]), and household food insecurity (AOR = 3.06, 95% CI [1.44-6.51]) were significantly increased the odds of acute undernutrition among pregnant women.

Conclusions

The study revealed that living in crowded families, lack prenatal dietary advice, did not participate in cooking demonstrations, substances use; lack of toilet, low minimum dietary diversity, and household food insecurity were significant risk factors for acute undernutrition among pregnant women. Strengthening multi-sectoral approaches through improving dietary diversity/quality and food access/quantity would be essential to prevent, and reduce the risks, burdens, and impacts of maternal undernutrition during pregnancy.

Risk of adverse newborn outcomes among women who experienced physical and psychological intimate partner abuse during pregnancy in Ghana's northern region

Background

Intimate partner violence (IPV) is common worldwide. However, the health effects of exposure to IPV during pregnancy are significantly more severe. We investigated the relationship between exposure to IPV during pregnancy and the risk of preterm and low birthweight births among women in Ghana's northern region.

Methods

We recruited 402 postnatal women aged 15-49 years from five selected public health facilities in the Tamale Metropolis of the northern region of Ghana. Using Kobo Collect, information on a wide range of factors, including exposure to IPV during the last pregnancy and pregnancy outcomes, was collected electronically. Multiple logistic regression analyses were conducted in Stata to determine the associations between prenatal exposure to IPV and binary measures of gestational age at birth and birthweight.

Results

Overall, 35.1% (95% CI: 30.5, 39.9) of the respondents experienced IPV during their recent pregnancy; 6.7% (95% CI: 4.6, 9.6) experienced physical IPV; and 34.8% (95% CI: 30.3, 39.6) experienced psychological IPV. The prevalence of preterm and low birthweight deliveries was 18.9% (95% CI: 15.4, 23.1) and 9.0% (95% CI: 6.5, 12.2), respectively. Prenatal exposure to IPV was linked to poor newborn outcomes by multivariable binary regression models. Women who suffered IPV during their last pregnancy were three times more likely to deliver low birthweight babies (AOR = 3.12: 95% CI: 1.42, 6.84). Exposed women were also about twice as likely to deliver prematurely, although this association was not statistically significant (AOR = 1.81; 95% CI: 0.97, 3.38).

Conclusion

Exposure to IPV during pregnancy increases a woman's risk of delivering prematurely and having a low birthweight baby. IPV screening should be a regular part of ANC, so that pregnant women who are experiencing IPV can be monitored and supported to avoid adverse outcomes for their babies.

Using household survey data to explore the effects of the domiciliary environment on weight at birth: a multilevel mixed-effects analysis of the 2016 Ethiopian Demographic Health Survey

BACKGROUND

Low birth weight (LBW) is associated with infant mortality and postpartum health complications. In previous studies, overall LBW has been found to be significantly associated with several sociodemographic factors, including ethnicity, maternal age, and family income. Few studies have evaluated the association between environmental risk factors and LBW rates. This study investigated the effect of pre-birth water, sanitation, and hygiene (WASH) and housing conditions on self-reported low birth weight.

METHODS

The Ethiopian Demographic and Health Survey, which covered all administrative regions of Ethiopia from January to June 2016, provided data for this study. STATA version 16 was used to analyze 12,125 participants across weighted samples. Multivariable multilevel mixed-effect logistic regression analysis was conducted to determine the effects of each factor on the outcome while accounting for data clustering. The adjusted odds ratios and corresponding 95% confidence intervals were used to determine the statistical significance of the independent variables.

RESULTS

One thousand five hundred and seventeen newborns, or 12.59% [95% CI (10.2- 15.3)], had low birth weights. When other factors were taken into account, the following factors were significantly associated with low birth weight: not using small-scale water treatment technology before using water [AOR (95% CI) 1.36 (1.08-2.23)], burning solid fuels for energy [AOR (95% CI) 1.99 (1.60-2.21)], living in homes with natural wall coverings [AOR (95% CI) 1.81 (1.47-2.21)], using a shared latrine within a woman's housing complex or compound [AOR (95% CI) 1.63(1.06-2.25)], and living in peripheral, isolated regions [AOR (95% CI) 1.38 (1.06-2.21)].

CONCLUSION

A little more than one out of every ten deliveries in Ethiopia was under normal (recommended) weight. This study shows that poor housing conditions and lack of household WASH infrastructure are independent predictors of poor birth outcomes among Ethiopian women, adding to the limited evidence that environmental factors within the domicile contribute to low birth weight. Interventions to address these issues may help lower the prevalence of LBW.

Policy to Decrease Low Birth Weight in Indonesia: Who Should Be the Target?

The study aimed to analyze the target of the policy to decrease low birth weight (LBW) in Indonesia. This cross-sectional study used a sample of live births in last five years preceding the survey of birth weight. Data collection took place from July to September 2017. The weighted sample size was 17,848 participants. The variables analyzed included residence, age, marital status, education, employment, parity, and wealth. The study employed binary logistic regression in the final stage to determine the target of policy regarding LBW. The results showed that women in urban areas were 1.200 times more likely to deliver babies with LBW than women in rural areas. All age groups were less likely to deliver babies with LBW than those aged 45-49. The study also found all marital statuses had a lower likelihood of providing babies with LBW than those who had never been in a marriage. Women of all education levels had a greater risk of giving birth to babies with LBW than women with higher education levels. Unemployed women had 1.033 times more chances of delivering babies with LBW than employed women. Primiparous women were 1.132 times more likely to give birth to babies with LBW than multiparous women. Overall, the women in all wealth status categories had a higher probability of delivering babies with LBW than the wealthiest groups. The study concluded that policymakers should target women who live in urban areas, are old, have never been married, have low education, and are unemployed, primiparous, and poor to decrease LBW cases in Indonesia.

Optimum birth interval (36-48 months) may reduce the risk of undernutrition in children: A meta-analysis

Background

Although some studies have highlighted short birth interval as a risk factor for adverse child nutrition outcomes, the question of whether and to what extent long birth interval affects better nutritional outcomes in children remains unclear.

Methods

In this quantitative meta-analysis, we evaluate the relationship between different birth interval groups and child nutrition outcomes, including underweight, wasting, and stunting.

Results

Forty-six studies with a total of 898,860 children were included in the study. Compared with a short birth interval of <24 months, birth interval of ≥24 months and risk of being underweight showed a U-shape that the optimum birth interval group of 36-48 months yielded the most protective effect (OR = 0.54, 95% CI = 0.32-0.89). Moreover, a birth interval of ≥24 months was significantly associated with decreased risk of stunting (OR = 0.61, 95% CI = 0.55-0.67) and wasting (OR = 0.63, 95%CI = 0.50-0.79) when compared with the birth interval of <24 months.

Conclusion

The findings of this study show that longer birth intervals (≥24 months) are significantly associated with decreased risk of childhood undernutrition and that an optimum birth interval of 36-48 months might be appropriate to reduce the prevalence of poor nutritional outcomes in children, especially underweight. This information would be useful to government policymakers and development partners in maternal and child health programs, especially those involved in family planning and childhood nutritional programs.

Effect of a theory-based nutrition education intervention during pregnancy through male partner involvement on newborns' birth weights in Southwest Ethiopia. A three-arm community based Quasi-Experimental study

BACKGROUND

Low birth weight is one of the most serious public health issues affecting newborns, with estimates ranging from 15% to 20% of all births worldwide. According to the Ethiopian demographic health survey report, the prevalence of Low Birth Weight rose from 11% in 2011 to 13% in 2016. The high proportion of birth weight in Ethiopia is hypothesized to be due to inadequate maternal diet which is associated with poor nutrition education during pregnancy. This study aimed to assess the effect of theory-based nutrition education during pregnancy through male partner involvement on birth weight in rural parts of the southwest Ethiopia.

STUDY DESIGN

A community-based quasi-experimental study was conducted.

METHODS

A total of 403 pregnant women were selected from 22 rural kebeles of Illu Aba Bor Zone, Southwest Ethiopia from June to December 2019. Participants were assigned to one of the three study arms: Couple group:-husband and wife received nutrition education together, women alone:-pregnant women received the nutrition education alone and control group:-received the routine care during Antenatal care. The nutrition education was guided by theory of planned behavior. Monthly home visits were made to the pregnant women in the intervention groups and leaflets with key counseling messages were distributed to each woman in the intervention arms. A structured interviewer-administered questionnaire was used to collect the data. A qualitative 24-h dietary recall was used to assess dietary data, and the Mid-Upper Arm Circumference was used to assess nutritional status. Birth weight was measured within 24 hours of birth. Analysis of variance, linear mixed-effects model, and mediation analysis were used to assess effect of the intervention on birth weight.

RESULTS

A higher proportion of the newborns in the control group had low birth weight as compared to the couple group and the women alone group (18.1% vs 7.0% vs 11.5%, p = 0.037) respectively. The mean birth weight of babies born to women from the couple group was 0.42 kg greater than that of newborns born to women in the comparison group (3.34 vs 2.92 kg, p< 0.001). The linear mixed effect model showed that the average birth weight of babies born from women in the couple group was 0.40 kg higher than that of the control group (β = 0.400, P<0.001). The direct effect of the intervention on birth weight of babies born from women in the couple group was 0.23 (β = 0.227, P<0.001) whereas the indirect effect mediated by maternal dietary diversity practice was 0.18 (β = 0.178, P<0.001), accounting for 43.9% of the total effect of the intervention.

CONCLUSION

The involvement of males and the application of the theory of planned behavior in nutrition education interventions during pregnancy resulted in improved birth weight. Maternal dietary diversity mediated the effect of nutrition education on birth weight. The findings highlight the implication of improving pregnant women's nutrition education through male involvement and the application of theories to improve birth weight.

Antenatal care utilization and compliance with national and WHO guidelines in rural Ethiopia: a cohort study

Background

Antenatal health care utilization has the potential to influence maternal and new-born health. In this study, we assessed compliance of antenatal care utilization with national and World Health Organization (WHO) guidelines. We also examined association of antenatal care utilization with adverse pregnancy outcomes as secondary outcome.

Methods

This was a community-based cross sectional study conducted from July 2016 to November 2017 in rural south-central Ethiopia. We described antenatal care received by pregnant women, whom we followed at three prescheduled visits during pregnancy and collected birth data at time of delivery. Extent of antenatal care content received, timing of antenatal care, place of antenatal care and place and mode of delivery were obtained and computed in accordance with national and WHO guidelines. For adverse pregnancy outcomes, computed as sum of low birth weight, preterm birth, intrauterine foetal death, and stillbirth, the exposure variable used was antenatal care utilization.

Results

Seven hundred and four (704) women participated in the study, and 536 (76.1%) had attended at least one antenatal care visit. Among women who attended antenatal care visit, majority, 421 (79.3%), had done so at health centres and hospitals, while 110 (20.7%) attended at health post. Average number of antenatal care visits was 2.5, which is less than that recommended in national and WHO guidelines. Only 18 (2.6%) women had attended antenatal care in their first trimester, which is low in contrast to the expected 100% specified in the guidelines. Less than half (47%) of the women delivered in a health facility. This is in contrast to the 100% expected health institution deliveries. Low birth weight was 7.9% (n = 48), and preterm birth was 4.9% (n = 31). There were 12 twin pregnancies, three stillbirths, 11 spontaneous abortions, and two intrauterine foetal deaths. We did not find significant association between adverse pregnancy outcomes and antenatal care utilization (COR = 1.07, 95% CI 0.62, 1.86).

Conclusion

This study showed that antenatal care service utilization in the study area was markedly low compared to that recommended in national and WHO guidelines. The obtained antenatal health care utilization was not associated with the registered adverse pregnancy outcomes.

Factors Associated with Number of Prenatal Visits in Northeastern Brazil: A Cross-Sectional Study

The aim of this study is to assess factors associated with the number of prenatal visits of women who delivered in a public maternity hospital in northeastern Brazil. This cross-sectional study focused on 380 puerperal women who gave birth at a public maternity hospital in northeastern Brazil. Prenatal and perinatal data were collected in the immediate postpartum period by interviewing mothers and using medical records. Chi-square/Fisher exact test compared the data, and a logistic regression model estimated the association between birth weight and number of prenatal visits. As a result, the sample was composed of 175 women with <37 weeks of gestational age and 205 women with ≥37 weeks of gestational age. Women with less than four prenatal visits were more likely to give birth to low birth weight (<2500 g) and preterm infants (<37 weeks of gestational age) than those with more than four prenatal visits (p = 0.001). The subjects with less than four prenatal visits had a 2.76-fold higher odds of giving birth to infants weighing less than 2500 g (p = 0.03; 95%CI = 1.05-7.30), without relation to maternal and gestational ages. In conclusion, women with less than four prenatal visits had higher odds of giving birth to low birth infants, independently of maternal and gestational ages, and were more likely to give birth to premature babies.

Prevalence of low birth weight and its associated factors: Hospital based cross sectional study in Nepal

Low birth weight is still an important public health problem worldwide. It is a major contributor to neonatal death in developing countries, including Nepal. The government of Nepal has developed and implemented different programs to improve maternal and neonatal health, including baby's birth weight. However, low birth weight is a major maternal and child health challenge. Maternal factors determining the birth weight of neonates have been poorly assessed in previous studies in Nepal. Thus, this study aims to assess the prevalence and risk factors associated with low birth weight in Nepal. An institution-based descriptive cross-sectional study was carried out in Paropakar Maternity Hospital and Tribhuvan University Teaching Hospital of Kathmandu district among 308 postnatal mothers. The data was collected through the face-to-face interview technique. The data was entered in EpiData 3.1 and exported to Statistical Package and Service Solutions version 21 for analysis. Multivariate logistic regression was used to obtain an adjusted odds ratio, while p-value < 0.05 with 95% Confidence Interval (CI) was considered significant. The findings showed that 15.3% of the children had low birth weight. The mean and standard deviation of childbirth weight was 2.96±0.59 kg. Mothers belonged to Dalit ethnic (AOR = 2.9, 95% CI = 1.2-7.1), Antenatal Care visited three or fewer (AOR = 2.6, 95%CI = 1.0-6.6) and did not comply with Iron and Folic Acid supplementation (AOR = 2.1, 95% CI = 1.0-4.4) were significantly associated with low birth weight. Nearly one in every six children had low birth weight. Maternal health services such as antenatal care and compliance with a recommended dose of maternal micronutrients significantly impact on birth weight. Maternal and neonatal health programs should consider these factors to reduce adverse birth outcomes in Nepal.

Immediate maternal and fetal outcome following percutaneous mitral valve balloon commissurotomy: a 6-year single-center experience from sub-Saharan Africa

BACKGROUND

Mitral stenosis is the most common valvular heart disease during pregnancy. When severe, it leads to significant maternal and fetal morbidity and mortality. Percutaneous mitral valve balloon commissurotomy can be performed during pregnancy, and the present study aimed to describe the immediate maternal and fetal outcomes after percutaneous mitral valve balloon commissurotomy was done in a cohort of 23 pregnant patients with severe mitral stenosis in Addis Ababa, Ethiopia.

METHODS

Included in the current study were all pregnant mothers who had severe rheumatic mitral valve stenosis and who underwent percutaneous mitral valve balloon commissurotomy at the Cardiac Center of Ethiopia over 6-year period. Data were collected through chart abstraction using a structured proforma and then analysed using STATA version 13.0.

RESULT

Median gestational age was 22 weeks and percutaneous mitral valve balloon commissurotomy was successful resulting in a significant increase in the mean mitral valve area of the group from 0.78 ± 0.20 cm² to 1.89 ± 0.31 cm² (p < 0.001). The mean mitral valve inflow gradient of the group was 23.95 ± 6.27 mmHg and 6.80 ± 2.44 mmHg, respectively, before and after the percutaneous mitral valve balloon commissurotomy procedure (p < 0.001). Post-procedure, there was no significant increment in mitral valve incompetence. The mean pulmonary artery pressure of the group decreased from 77.68 ± 23.19 mmHg to 42.31 ± 9.95 mmHg (p < 0.001). There was no fetal or maternal death following the procedure. Pregnancy ended at term gestation for 19/23 (82.6%) of the mothers and the mean birth weight of the neonates was 2800 g.

CONCLUSION

Percutaneous mitral valve balloon commissurotomy procedure can safely be done for severe symptomatic rheumatic mitral stenosis in pregnancy in our setting.

Machine learning algorithms for predicting low birth weight in Ethiopia

Background

Birth weight is a significant determinant of the likelihood of survival of an infant. Babies born at low birth weight are 25 times more likely to die than at normal birth weight. Low birth weight (LBW) affects one out of every seven newborns, accounting for about 14.6 percent of the babies born worldwide. Moreover, the prevalence of LBW varies substantially by region, with 7.2 per cent in the developed regions and 13.7 per cent in Africa, respectively. Ethiopia has a large burden of LBW, around half of Africa. These newborns were more likely to die within the first month of birth or to have long-term implications. These are stunted growth, low IQ, overweight or obesity, developing heart disease, diabetes, and early death. Therefore, the ability to predict the LBW is the better preventive measure and indicator of infant health risks.

Method

This study implemented predictive LBW models based on the data obtained from the Ethiopia Demographic and Health Survey 2016. This study was employed to compare and identify the best-suited classifier for predictive classification among Logistic Regression, Decision Tree, Naive Bayes, K-Nearest Neighbor, Random Forest (RF), Support Vector Machine, Gradient Boosting, and Extreme Gradient Boosting.

Results

Data preprocessing is conducted, including data cleaning. The Normal and LBW are the binary target category in this study. The study reveals that RF was the best classifier and predicts LBW with 91.60 percent accuracy, 91.60 percent Recall, 96.80 percent ROC-AUC, 91.60 percent F1 Score, 1.05 percent Hamming loss, and 81.86 percent Jaccard score.

Conclusion

The RF predicted the occurrence of LBW more accurately and effectively than other classifiers in Ethiopia Demographic Health Survey. Gender of the child, marriage to birth interval, mother’s occupation and mother’s age were Ethiopia’s top four critical predictors of low birth weight in Ethiopia.

Incidence of adverse perinatal outcomes and risk factors among women with pre-eclampsia, southern Ethiopia: a prospective open cohort study

BACKGROUND

In Ethiopia, in 2021, more than 80% of all newborn deaths were caused by preventable and treatable conditions. This study aimed to measure the incidence of adverse perinatal outcomes and risk factors among women with pre-eclampsia in the Sidama region of southern Ethiopia.

METHODS

A prospective open cohort study was conducted from 8 August 2019 to 1 October 2020. We enrolled 363 women with pre-eclampsia and 367 normotensive women at ≥20 weeks of gestation and followed them until the 37th week. We then followed them until the seventh day after delivery up to the last perinatal outcome status was ascertained. A log-binomial logistic regression model was used to estimate the incidence of adverse perinatal outcomes and its risk factors among women with pre-eclampsia. Relative risk (RR) with a 95% CI was reported. A p<0.05 was considered statistically significant.

RESULTS

There were 224 adverse perinatal outcomes observed in the 363 women with pre-eclampsia compared with 136 adverse perinatal outcomes in the 367 normotensive women (p<0.001). There were 23 early neonatal deaths in the pre-eclampsia group compared with six deaths in the normotensive group (p<0.001). There were 35 perinatal deaths in the pre-eclampsia group compared with 16 deaths in the normotensive group (p<0.05). Women with severe features of pre-eclampsia had a 46% (adjusted RR 1.46, 95% CI 1.38 to 2.77) higher risk for adverse perinatal outcomes compared with women without severe features of pre-eclampsia.

CONCLUSIONS

In this study, more adverse perinatal outcomes occurred among women with pre-eclampsia after controlling for confounders. A higher perinatal outcome observed among women with pre-eclampsia, especially among women with severe features of pre-eclampsia, and those admitted to hospital at <34 weeks. This paper highlights the significantly elevated perinatal risks associated with pre-eclampsia, especially when it has severe features.

Prevalence, predictors of low birth weight and its association with maternal iron status using serum ferritin concentration in rural Eastern Ethiopia: a prospective cohort study

Introduction

Low birth weight (LBW) is one of the major predictors of perinatal survival, infant morbidity, and mortality, as well as the risk of developmental disabilities and illnesses in future lives. The effect of the nutritional status of pregnant women on birth outcomes is becoming a common research agenda, but evidence on the level of low birth weight (LBW) and its association with prenatal iron status in Ethiopia, particularly among rural residents, is limited. Thus, this study aimed to assess the prevalence, predictors of LBW, and its association with maternal iron status using serum ferritin concentration in Haramaya district, eastern Ethiopia, 2021.

Methods

A community-based prospective cohort study design was conducted. Of a total of 427 eligible pregnant women followed until birth, 412 (96.48%) were included in the final analysis. Iron status was determined using serum ferritin (SF) concentration from venous blood collected aseptically from the ante-cubital veins analyzed on a fully automated Cobas e411 (German, Japan Cobas 4000 analyzer series) immunoassay analyzer. Iron deficiency(ID) and iron deficiency anemia (IDA) were classified as having SF less than 15 μg/L and SF less than 15 μg/L and Hb level of < 11.0 g/dl during the first or third trimester or < 10.5 g/dl during the second trimester as well, respectively. Birthweight was measured within 72 h of birth and < 2500 g was considered LBW. Birthweight was measured within 72 h of birth and < 2500 g was considered as LBW. A Poisson regression model with robust variance estimation was used to investigate the factors associated with LBW and the association between maternal iron status and LBW. An adjusted prevalence ratio with a 95% confidence interval was reported to show an association using a p-value < 0.05.

Results

About 20.2% (95% CI: 16%-24%) of neonates were born with LBW. The prevalence of LBW was 5.04 (95% CI = 2.78–9.14) times higher among women who were iron deficient during pregnancy compared to those who were normal. The neonates of women who were iron deficient during pregnancy had lower birth weight (aPR=5.04; 95% CI = 2.78–9.14) than the neonates of women who were normal. Prevalence of LBW was higher among mothers who were undernourished (MUAC < 23cm) (aPR = 1.92; 95% CI= 1.33–2.27), stunted (height <145cm) (aPR=1.54; 95% CI=1.04–2.27) and among female neonates (aPR=3.70; 95% CI= 2.28–6.00). However, women who were supplemented with iron and folic acid (IFAS) during pregnancy had a 45% decreased chance of delivering low birth weight (aPR= 0.55; 95% CI=0.36–0.84).

Conclusion

We found that LBW is of public health significance in this predominantly rural setting. ID during pregnancy is found to have a negative effect on birth weight. IFA supplementation, the maternal under-nutrition, height, and sex of neonates were identified as predictors of low weight at birth. To improve maternal nutritional status, health interventions must address targeted strategies promoting desirable food behavior and nutritional practices. These include; promoting the consumption of diversified and rich iron food to improve the maternal nutritional status. A continued effort is needed in enhancing universal access and compliance with IFA supplementation to improve maternal health. Intervention strategies that are complementary and comprehensive across the vulnerable periods for women during pregnancy and their neonates that are based on a life-cycle approach are suggested.

Influence of gestational weight gain on baby's birth weight in Addis Ababa, Central Ethiopia: a follow-up study

BACKGROUND

Gestational weight gain (GWG) is an important indicator of fetal well-being during pregnancy. Inadequate or excessive GWG could have undesirable effects on birth weight. However, information regarding the influence of GWG on birth weight is lacking from the Ethiopian setting.

OBJECTIVE

This study aimed to determine the influence of GWG and other maternal-related factors on birth weight in Addis Ababa, Ethiopia.

DESIGN AND METHODS

A cohort of pregnant women who received the first antenatal care before or at 16 weeks of gestation in health centres in Addis Ababa were followed from 10 January 2019 to 25 September 2019. Data were collected using a structured questionnaire and medical record reviews. We conducted a multivariable linear regression analysis to determine the independent effect of gestational weight on birth weight.

RESULTS

Of the 395 women enrolled in the study, the participants' pregnancy outcome was available for 329 (83.3%). The mean birth weight was 3130 (SD, 509) g. The proportion of low birth weight (<2500 g) was 7.5% (95% CI 4.8% to 11.0%). Babies born to underweight women were 150.9 g (95% CI 5.8 to 308.6 g, p=0.049) lighter than babies born to normal-weight women. Similarly, babies whose mothers gained inadequate weight were 248 g (95% CI 112.8 to 383.6 g, p<0.001) lighter than those who gained adequate weight. Moreover, babies whose mothers had a previous history of abortion or miscarriages or developed gestational hypertension in the current pregnancy were 147.2 g (95% CI 3.2 to 291.3 g, p=0.045) and 310.7 g (95% CI 62.7 to 552.8 g, p=0.012) lighter, respectively, compared with those whose mothers had not.

CONCLUSIONS

Prepregnancy weight, GWG, having had a previous history of abortion or miscarriages, and developing gestational hypertension during a current pregnancy were independently associated with birth weight. Pregnancy-related weight management should be actively promoted through intensive counseling during routine antenatal care contacts.

Risk factors associated with low birth weight

OBJECTIVES

Low birth weight (LBW) is one of the major factors affecting child morbidity and mortality worldwide. Every day, approximately 800 women die from causes related to pregnancy and childbirth worldwide. Maternal ill health increases the risk of LBW. This study seeks to investigate determinants and incidence of LBW.

METHODS

This study was conducted based on the medical records of mothers and their 1,946 infants born in 2016-2019 at the Department of Gynaecology and Obstetrics of Louis Pasteur University Hospital in Košice. Data on mothers and newborn infants were obtained from the Reports on mothers at childbirth. The inclusion criteria were singleton births and birth weight > 500 g. The exclusion criteria were twins or multiple births, congenital anomalies and stillbirths, birth weight ≥ 4,000 g or ≤ 500 g, and Roma ethnicity. Roma children are more likely to be born prematurely, with low birth weight. Roma mothers have different lifestyle. Univariate analysis was employed to evaluate the association between the independent variables and LBW. Variables that were found to be statistically significant were then further analysed using multivariable logistic analysis for each dependent variable. The implementation of the research was approved by the Ethics Committee.

RESULTS

Of 1,946 newborns, 271 (13.90%) have low birth weight. The mean of birth weight at delivery was 3,068.62 (SD 671.16) grams. Factors that were associated with LBW were primary maternal education (OR = 2.98, 95% CI: 1.08-8.21, p = 0.034), marital status single (OR = 2.88, 95% CI: 1.68-4.94, p < 0.001), number of prenatal care visits less than 8 (OR = 1.62, 95% CI: 1.01-2.61, p = 0.047), and preterm birth (OR = 74.94, 95% CI: 45.44-123.61, p < 0.001).

CONCLUSION

The reducing of LBW requires strategies to improve maternal lifestyle, maternal care before, during and after birth and to strengthen social support.

Does family planning counselling during health service contact improve postpartum modern contraceptive uptake in Ethiopia? A nationwide cross-sectional study

OBJECTIVE

This study examined the association between family planning counselling receipt during the 12 months preceding the survey and postpartum modern contraceptive uptake in Ethiopia. We hypothesised that receiving family planning counselling either within the community setting by a field health worker or at a health facility by a healthcare attendant during the 12 months preceding the survey improves postpartum modern contraceptive uptake.

DESIGN

We used a cross-sectional study of the Ethiopian Demographic and Health Survey conducted in 2016.

SETTING

Ethiopia.

PARTICIPANTS

A total of 1650 women who gave birth during the 12 months and had contact with service delivery points during the 12 months preceding the survey.

PRIMARY OUTCOME

A weighted modified Poisson regression model was used to estimate an adjusted relative risk (RR) of postpartum modern contraceptives.

RESULTS

Approximately half (48%) of the women have missed the opportunity to receive family planning counselling at the health service contact points during the 12 months preceding the survey. The postpartum modern contraceptive uptake was 27%. Two hundred forty-two (30%) and 204 (24%) of the counselled and not counselled women used postpartum modern contraceptive methods, respectively. Compared with women who did not receive counselling for family planning, women who received counselling had higher contraceptive uptake (RR 1.32, 95% CI 1.04 to 1.67).

CONCLUSION

Significant numbers of women have missed the opportunity of receiving family planning counselling during contact with health service delivery points. Modern contraceptive uptake among postpartum women was low in Ethiopia. Despite this, our findings revealed that family planning counselling was associated with improved postpartum modern contraceptive uptake.

Knowledge, attitude and practice towards kangaroo mother care among postnatal women in Ethiopia: Systematic review and meta-analysis

BACKGROUND

Kangaroo mother care is a key procedure in reducing neonatal mortality and morbidity associated with preterm birth. In Ethiopia, neonatal death remains a serious problem, and this study aims to determine the prevalence of the knowledge, attitudes and practice of kangaroo mother care among Ethiopia women.

METHODS

PubMed, Web of Science, Google Scholar, EMBASE and the Ethiopian University online library were searched. Data were extracted using Microsoft Excel and analysed using STATA statistical software (v. 11). Publication bias was checked by forest plot, Begg's rank test and Egger's regression test. To look for heterogeneity, I2 were computed and an overall estimated analysis carried out. Subgroup analysis was done by region, study setting, publication, gestational age, birth weight and component of kangaroo care. The Joanna Briggs Institute risk of bias assessment tool was used. We carried out a leave one out sensitivity analysis.

RESULTS

Out of 273 articles retrieved, 16 studies met the eligibility criteria and are thus included in this study. Those 16 studies had a total of 12,345 respondents who reported kangaroo mother practice, with five (comprising 1,232 participants combined) reporting that both knowledge and attitude were used to determine the overall estimation. The pooled estimates of good knowledge, positive attitude and poor practice of kangaroo mother care were found to be 64.62% (95% CI: 47.15%-82.09%; I2 = 97.8%), 61.55% (49.73%-73.38%; I2 = 94.8%) and 45.7% (95% CI: 37.23%-54.09%; I2 = 98.5%), respectively. This study is limited to postnatal women and does not take account their domestic partners or health providers.

CONCLUSION

The findings revealed significant gaps in the knowledge, attitudes and practice of kangaroo mother care in Ethiopia when compared with other developing countries. Therefore, kangaroo mother care training to women, along with further studies on domestic partners and health providers.

Effect of Nutrition Interventions Before and/or During Early Pregnancy on Low Birth Weight in Sub-Saharan Africa: A Systematic Review and Meta-Analysis

BACKGROUND

This review aimed at synthesizing evidence on the effectiveness of nutritional interventions that were carried out before and/or during early pregnancy versus the control groups on reducing the risk of low weight at birth in sub-Saharan Africa.

METHODS

We have searched on MEDLINE, SCOPUS, CINAHL, HINARI, and Cochrane Library of systematic review databases for published articles in English language from 2010 to 2021 years. For unpublished studies, we searched on Google scholar. Randomized controlled trial studies of nutritional interventions carried out before/or during early pregnancy in sub-Saharan Africa to improve low birth weight were considered. The data were extracted and pooled using the Joanna Briggs Institute software. The effect size was calculated using fixed-effect models. Mantel-Haenszel method was used to calculate the relative risk with their respective 95% CI. Heterogeneity was assessed using the standard chi-square and I ² tests.

RESULTS

Seven studies were included in the review with a total of 5934 participants. Three types of nutritional interventions were identified: iron supplementations, lipid-based supplementations, and nutritional education and counseling. We have identified only one intervention started during preconception. The meta-analysis showed that none of the identified nutrition interventions had a statistically significant effect on low birth weight.

CONCLUSIONS

Based on the review evidence, nutritional interventions before and/or during early pregnancy in sub-Saharan Africa had no significant effect on low birth weight. However, since our evidence was derived from a small number of trials and participants, a large-scale randomized controlled trials review might be required to elucidate the finding.

Maternal and neonatal factors associated with low birth weight among neonates delivered at the University of Gondar comprehensive specialized hospital, Northwest Ethiopia

INTRODUCTION

Low birth weight is a major contributory factor to infant mortality. Although low birth weight remains an important public health problem in Ethiopia, little emphasis is paid to its intervention as a means of reducing neonatal mortality. The aim of this study was to assess the magnitude of low birth weight and its associated maternal and neonatal factors in newborns delivered at the University of Gondar Comprehensive Specialized Hospital.

METHODS

Hospital-based cross-sectional study was conducted, and 481 study participants were selected using systematic random sampling methods. Pre-tested interviewer-administered questionnaires were used to collect the data. Bivariable and multivariable binary logistic regression was implemented. Finally, the odds ratio with a 95% CI and a p-value of <0.05 were used to identify factors associated with low birth weight.

RESULT

The prevalence of low birth weight was 12.5% (95% CI; 9.8, 15.7%). Preterm birth (AOR = 38; 95% CI: 15.3, 93.0), pregnancy-induced hypertension (PIH) (AOR = 2.6; 95%CI: 1.1, 6.4), maternal body mass index (BMI) of < 18.5 kg/m² (AOR = 6.8; 95% CI: 1.5, 31.1), and grand multiparity (AOR = 4.2; 95% CI: 1.2, 16) were factors positively associated with low birth weight. However, babies delivered from mothers with age > 35 years (AOR = 0.14:95% CI 0.03, 0.7) had lower odds of low birth weight.

CONCLUSION

In this study, the prevalence of low birth weight was higher than in the previous studies. The study revealed preterm birth, PIH, BMI of < 18.5 kg/m², and grand multiparity were independent factors that increase the low birth weight while maternal age > 35 years reduces the low birth weight. Therefore, healthcare professionals should emphasize the early identification and management of women with PIH, tackling prematurity, and preventing maternal malnutrition through nutritional counseling as much as possible.

Lived experiences of women with low birth weight infants in the Solomon Islands: A descriptive qualitative study

Every year, around 20 million women worldwide give birth to low birth weight (LBW) infants, with majority of these births occurring in low-and middle-income countries, including the Solomon Islands. Few studies have explored the pregnancy lived experience of women who deliver LBW infants. The aim of the study is to understand the lived experience of women in the Solomon Islands who gave birth to LBW infants by exploring their personal (socio-demographic and health), behavioural, social and environmental contexts. We used a qualitative descriptive approach and purposely selected 18 postnatal women with LBW infants in the Solomon Islands for an in-depth interview. All data were analysed using thematic analysis in NVivo. We identified six themes reported as being related to LBW: health issues, diet and nutrition, substance use, domestic violence, environmental conditions and antenatal care. Our findings suggest that women in the Solomon Islands are exposed to various personal, behavioural, social and environmental risk factors during pregnancy that can impact birth outcomes, particularly LBW. We recommend further research should be redirected to look at the factors/themes identified in the interviews.

Maternal Undernutrition and Low Birth Weight in a Tertiary Hospital in Sudan: A Cross-Sectional Study

BACKGROUND

The World Health Organization set a Global Nutrition Target of a 30% reduction in LBW by 2025. Maternal malnutrition/undernutrition is among the most important modifiable risk factors for impaired fetal growth. This study investigates the effect of maternal undernutrition on LBW in Sudan.

METHODS

A cross-sectional study was conducted at Saad Abuelela Hospital in Khartoum, Sudan, from May to October 2020. The sociodemographic and obstetric data of the women were gathered via questionnaire, and their mid-upper arm circumference (MUAC) was measured. Maternal undernutrition was defined as a MUAC of <23 cm.

RESULTS

In total, 1,505 pairs of pregnant women and their newborns were enrolled in the study. The medians [interquartile (IQR)] of the age, parity, and gestational age were 27.0 (9.0) years, 1.0 (3.0), and 38.0 (2.0) weeks, respectively. The median (IQR) of the birth weight was 3,028.0 (690.0) g. Of the 1,505 participants, 182 (12.1%) delivered LBW infants. Multivariate logistic regression showed that MUAC [adjusted odds ratio (AOR) = 0.91, 95% confidence interval (CI) = 0.87-0.96] and gestational age (AOR = 0.79, 95% CI = 0.73-0.85) were negatively associated with LBW. The level of antenatal care <2 visits (AOR = 2.10, 95% CI = 1.30-3.57) was associated with LBW. Women with undernutrition were at a higher risk of delivering LBW infants (AOR = 1.66, 95% CI = 1.09-2.53).

CONCLUSION

LBW is a health problem in Sudan, and women with undernutrition were at a higher risk of delivering LBW infants.

Birth prevalence of encephalocele in Africa: a systematic review and meta-analysis

Objective

To identify the birth prevalence of encephalocele in Africa, 2020.

Methods

We carried out a systematic search of the following databases (PubMed/Medline, PubMed Central, Joanna Briggs Institute (JBI) Library, Cochrane Library, Web of Science, Google Scholar, Science Direct, African Journals Online and Embase), using search terms (prevalence, encephalocele, “neural tube defects”, “cranium bifidum”, “congenital malformations”, “congenital defects”, “structural birth defects”, “structural abnormalities”, newborns/neonates/ “live births”/ “stillbirths” and their MeSH Terms) up to 16 July 2021. The JBI quality appraisal checklist was used to assess the quality of studies when they were abstracted using a standardised data extraction template. The I² statistic and Cochrane Q test were used to examine heterogeneity across studies statistically. The prevalence of encephalocele was estimated using a random-effect meta-analysis model. Subgroup, sensitivity, meta-regression and time trend analysis were carried out. The publication bias was checked using Egger and Begg’s tests.

Results

Twenty-seven relevant studies were identified and provided a total of 5 107 109 births. In this systematic review and meta-analysis, the pooled birth prevalence of encephalocele in Africa was 0.02% (or 2 per 10 000 births) (95% CI 0.02% to 0.03%). The overall prevalence of birth encephalocele using the median from studies was 0.02% (IQR=0.01%–0.04%). Higher prevalence of encephalocele was detected in Nigeria 0.06% (95% CI 0.04% to 0.08%), Sudan 0.04% (95% CI 0.03% to 0.05%), Egypt 0.04% (95% CI 0.04% to 0.05%), DR of Congo 0.02% (95% CI 0.02% to 0.03%), Ethiopia 0.02% (95% CI −0.004% to 0.05%) and Tanzania 0.02% (95% CI 0.002% to 0.04%). The prevalence of encephalocele per live birth was 0.03% and both live birth and stillbirth was 0.03%.

Conclusions

This review indicates a high prevalence of encephalocele, but studies were limited suggesting the need for additional research.

Determinants of low birth weight among newborns delivered at Tirunesh Beijing General Hospital, Addis Ababa, Ethiopia: a case-control study

BACKGROUND

Low birth weight is weight less than 2500 g or 5.5 lb. at birth. Globally, more than 20 million infants (15-20%) are born with a low birth weight each year. Birth weight is the primary indicator of the health status of neonates and is the primary factor that determines the infant's physical, survival, and mental growth. Thus, the study aimed to investigate the determinants of low birth weight among newborn babies delivered at Tirunesh Beijing General Hospital, Addis Ababa, Ethiopia.

METHODS

We performed a facility-based unmatched case-control study among 453 (151 cases and 302 controls) deliveries conducted at Tirunesh Beijing General Hospital. Birth records and maternal antenatal care (ANC) files were reviewed from March 1 to April 30, 2019. Consecutive sampling was employed to select study participants. Data were entered into Epi-data version 4.2.1 and analyzed using SPSS version 25 statistical software. Descriptive statistics and logistic regression analysis were computed to identify independent determinants of low birth weight. A p-value of ≤0.05 was used to declare statistical significance.

RESULT

Four hundred fifty-three birth records of babies (151 cases and 302 controls) were reviewed. Women who reside in rural area [AOR (CI) = 3.12 (1.63-5.98)], being merchant [(AOR (CI) = 2.90 (1.03-8.22)], danger sign during pregnancy [(AOR (CI) = 4.14 (1.68-10.2)], and maternal weight during pregnancy [(AOR (CI) = 4.94 (3.26-7.52)] were found to be a significant determinants of low birth weight.

CONCLUSION

Residence, occupation, danger signs, and maternal weight during pregnancy were significant determinants of low birth weight. Socioeconomic development, early detection and management of complications, and encouraging nutrition and weight during pregnancy are crucial for minimizing the risk of delivering low birth weight babies.

Malnutrition and contributing factors among newborns delivered at the University of Gondar Hospital, Northwest Ethiopia: a cross-sectional study

OBJECTIVES

To estimate the prevalence of various indicators of malnutrition (stunting, wasting, low birth weight, concurrent stunting and wasting, overweight/obesity and double burden malnutrition) among newborns and to investigate factors associated with these nutritional disorders.

METHODS

A hospital-based cross-sectional study was conducted from 10 March through to May 2020. A total of 419 newborns were recruited into the study to estimate the prevalence of low birth weight and stunting. After excluding 28 newborns whose length was less than 45 cm, 394 newborn-mother dyads were approached to estimate wasting and overweight/obesity. A systematic random sampling technique was used to select participants. All independent variables were entered into the multivariable logistic regression model and variables that had significant associations were identified based on a p value.

RESULTS

A very small proportion of the newborns 2.5% (0.9% to 4.1%) were concurrently wasted and stunted. The prevalence rates of low birth weight and wasting were 20.8% (16.8% to 24.6%) and 10.9% (7.82% to 14.01%), respectively. The magnitude of overweight/obesity was 12.7% (9.3% to 15.9%) where 2.8% (1.1% to 4.4%) of newborns have the double burden of malnutrition. Having a father with a primary level of education 2.82 (1.19 to 6.65) and being stunted at birth 3.17 (1.6 to 6.0) were variables that were associated with increased odds of low birth weight. The odds of being overweight/obese are significantly higher among newborns born to mothers who are urban dwellers 0.35 (0.12 to 0.99).

CONCLUSIONS

The study underscores that malnutrition is a pressing public health concern that demands due emphasis. Fathers' educational status (low level) and being stunted are associated with a high burden of low birth weight. Mothers' residency (being urban) is associated with an elevated risk of overweight/obesity among newborns. Thus, improving the health literacy of fathers and preventing stunting at birth are recommended to mitigate low birth weight.

Determinants of low birth weight deliveries at five referral hospitals in Western Area Urban district, Sierra Leone

Background

Low birth weight (LBW) contributes significantly to infant and child mortality. Each year, about 20 1million deliveries are LBW with 96.5% occurring in developing countries. Whiles the incidence of LBW is reducing in other districts of Sierra Leone, it has been reported to be increasing in the Western Area Urban district. Determining the risk factors in a specific geographic area is important for identifying mothers at risk and thereby for planning and taking appropriate action. The current study sought to identify factors associated with LBW deliveries in the Western Area Urban district of Sierra Leone.

Methods

A hospital-based unmatched 1:2 case-control study was conducted among mothers who delivered live singleton babies from November, 2019 to February, 2020 in five referral health facilities. Mothers were conveniently sampled and sequentially enrolled into the study after delivery. Their antenatal care cards were reviewed and a pre-tested questionnaire administered to the mothers. Data analysis was done using Stata 15.0 and association between maternal socio-demographic, socio-economic, obstetric and lifestyle factors and LBW assessed using bivariable and multivariable logistic regression analyses.

Results

A total of 438 mothers (146 cases and 292 controls), mean age: 24.2 (±5.8) and 26.1 (±5.5) years for cases and controls respectively participated in the study. Multivariable analysis revealed that being unemployed (AoR = 2.52, 95% CI 1.16–5.49, p = 0.020), having anaemia during pregnancy (AoR = 3.88, 95% CI 1.90–7.90, p <  0.001), having less than 2 years inter-pregnancy interval (AoR = 2.53, 95% CI 1.11–5.73, p = 0.026), and smoking cigarettes during pregnancy (AoR = 4.36, 95% CI 1.94–9.80, p <  0.001) were significantly associated with having LBW babies.

Conclusion

Factors associated with LBW identified were unemployment, anaemia during pregnancy, < 2 years inter-pregnancy interval and cigarette smoking during pregnancy. Health care providers should screen and sensitize mothers on the risk factors of LBW during antenatal sessions.

Low birth weight and birth weight status in Bangladesh: A systematic review and meta-analysis

The prevalence of low birth weight (LBW) is high in Bangladesh, but no study has collated recent estimates of LBW prevalence from throughout the country. The aim of this meta-analysis was to evaluate the prevalence of LBW and birth weight status in Bangladesh. We searched PubMed, Medline, Ovo and Google Scholar to find published articles in national and international journals from 2000–2020 and reviewed for relevance. Meta-analysis and Q test were performed to estimate the prevalence and heterogeneity of LBW from all included articles. Meta-regression was done to quantify associations with sample size and study year. Stratified analysis was conducted and effect size calculated for differences in LBW prevalence by sex, division and urban/rural area. In total 48 studies with 166,520 births were found and included in this meta-analysis. The pooled prevalence of LBW was 29.1% (95% CI, 28.9–29.3%) in overall, 29.9% (29.7–30.2%) in rural and 15.7% (14.9–16.6%) in urban areas. There was no significant difference in average birth weight between boys and girls (SD, 0.71; 95% CI, −0.43–1.83). Prevalence of LBW was higher in north-east Bangladesh compared to other zones (p<0.05). The pooled prevalence of LBW did not change significantly for last two decades. The prevalence of LBW in Bangladesh remains high. Lack of improvement suggests an urgent need for scaled up maternal and prenatal interventions and services known to reduce LBW. Urban/rural and divisional differences in rates suggest areas of greatest need.

Effect of birthweight measurement quality improvement on low birthweight prevalence in rural Ethiopia

BACKGROUND

Low birthweight (LBW) (< 2500 g) is a significant determinant of infant morbidity and mortality worldwide. In low-income settings, the quality of birthweight data suffers from measurement and recording errors, inconsistent data reporting systems, and missing data from non-facility births. This paper describes birthweight data quality and the prevalence of LBW before and after implementation of a birthweight quality improvement (QI) initiative in Amhara region, Ethiopia.

METHODS

A comparative pre-post study was performed in selected rural health facilities located in West Gojjam and South Gondar zones. At baseline, a retrospective review of delivery records from February to May 2018 was performed in 14 health centers to collect birthweight data. A birthweight QI initiative was introduced in August 2019, which included provision of high-quality digital infant weight scales (precision 5 g), routine calibration, training in birth weighing and data recording, and routine field supervision. After the QI implementation, birthweight data were prospectively collected from late August to early September 2019, and December 2019 to June 2020. Data quality, as measured by heaping (weights at exact multiples of 500 g) and rounding to the nearest 100 g, and the prevalence of LBW were calculated before and after QI implementation.

RESULTS

We retrospectively reviewed 1383 delivery records before the QI implementation and prospectively measured 1371 newborn weights after QI implementation. Heaping was most frequently observed at 3000 g and declined from 26% pre-initiative to 6.7% post-initiative. Heaping at 2500 g decreased from 5.4% pre-QI to 2.2% post-QI. The percentage of rounding to the nearest 100 g was reduced from 100% pre-initiative to 36.5% post-initiative. Before the QI initiative, the prevalence of recognized LBW was 2.2% (95% confidence interval [CI]: 1.5-3.1) and after the QI initiative increased to 11.7% (95% CI: 10.1-13.5).

CONCLUSIONS

A QI intervention can improve the quality of birthweight measurements, and data measurement quality may substantially affect estimates of LBW prevalence.

Survival Status and Predictors of Mortality Among Low-Birth-Weight Neonates Admitted to the Neonatal Intensive Care Unit at Felege Hiwot Comprehensive Specialized Hospital, Bahir Dar, Ethiopia, 2020

BACKGROUND

Low birth weight neonates are subjected to different comorbidities due to anatomical and physiological immaturity. Globally, 60-80% of neonatal mortality was due to low birth weight. Hence, this study aimed to assess the survival status and predictors of mortality among low birth weight neonates.

METHODS

An institutional-based retrospective cohort study design was conducted among 718 low birth weight neonates admitted to the neonatal intensive care unit from January 1, 2017, to December 30, 2019, at Felege Hiwot Comprehensive Specialized Hospital. Data were entered into Epi data version 3.1 and analyzed with STATA version 14. Kaplan-Meier curves together with a Log rank test were used to estimate the survival time and showed the presence of differences among groups. Cox proportional-hazard regression was used to estimate the hazard ratio at the 5% level of significance to determine the net effect of each explanatory variable on survival status.

RESULTS

The overall incidence density was 35.3 per 1000 person-day observations (CI: 30.8 -40.6) with 5715 follow-up days. Deliveries outside the health institution [AHR; 2.31 (95% CI: 1.20-4.42)], maternal age <18 years [AHR; 3.08 (95% CI: 1.64-5.81)] and maternal age >35 years [AHR; 3.83 (95% CI: 2.00-7.31)], neonatal sepsis [AHR; 2.33 (95% CI: 1.38-3.94)], neonatal respiratory distress syndrome [AHR; 1.92 (95% CI: 1.27-2.89)], necrotizing enterocolitis [AHR; 3.09 (95% CI: 1.69-5.64)] and birth weight <1000 gm [AHR; 3.61 (95% CI: 1.73-7.55)] were found to be significant predictors.

CONCLUSION

This study showed that two of the seven low birth weight neonates died during the follow-up period. Therefore, it is better for health care providers and other stakeholders to focus more on early diagnosis and management of low birth weight neonates with sepsis, respiratory distress syndrome, necrotizing enterocolitis and counseling mothers on the risk of having a child in early and old age.

Trends and Determinants of Small Birth Weight in Ethiopia: Further Analysis of Ethiopian Demographic and Health Surveys

Background

Globally, Low Birth Weight (LBW) prevalence is estimated to be 14.6%. It is a major cause of neonatal mortality in developing countries including Ethiopia. Despite extensive institution-based studies in Ethiopia, there is no comprehensive study using countrywide data. Thus, this study aimed to investigate trends and determinants of Small Birth Weight (SBW) among under-five children in Ethiopia.

Methods

Under-five children data from 2000, 2005, 2011, and 2016 Ethiopian Demographic and Health Surveys (EDHS) were used. However, only 2787 children were weighed at birth and used for analysis in this study. Descriptive statistics and the logistic regression model were used to determine trends and determinants of SBW respectively.

Results

The prevalence of SBW increased from 7.0% (95% CI; 3.1–10.0) to 13.2% (95% CI; 11.4–15.0) between 2000 and 2016. The odds of SBW increased by being a female child (AOR 1.50; 95% CI [1.07–2.09]), mother's with partner occupation of agriculture (AOR 1.54; 95% CI [1.05–2.26]) and mothers who did not know their partner's occupation (AOR 7.35; 95% CI [1.96–27.48]). However, infants born to mothers with primary (AOR 0.43; 95% CI [0.29–0.65]), secondary (AOR 0.30; 95% CI [0.16–0.55]) and higher (AOR 0.55; 95% CI [0.31–0.97]) educational status versus no education and grandmultiparous mothers (OR 0.39; 95% CI [0.19–0.78]) versus primiparous had lower odds of SBW.

Conclusion

In Ethiopia, during the survey period, there was an increment in prevalence of SBW, and maternal related factors were significant determinants. Therefore, empowering mothers through education and improving the socioeconomic status of the household can be one strategy to reduce SBW.

Patterns and predictors of gestational weight gain in Addis Ababa, Central Ethiopia: a prospective cohort study

INTRODUCTION

Gaining excessive or inadequate gestational weight is associated with many adverse maternal and fetal outcomes. Inadequate gestational weight gain (GWG) increases the risk of fetal growth restriction, pre-term birth, and low birth weight. It is a public health concern in sub-Saharan Africa. The aim of this study was to assess the patterns and predictors of GWG in Addis Ababa, Ethiopia.

METHODS

We conducted a prospective cohort study among pregnant women who attended antenatal care in health centres in Addis Ababa, from January to September 2019. Data were collected by a structured questionnaire and checklists and analysed using Stata version-14. Weight at or before 16 weeks gestation was used as a proxy for pre-pregnancy weight. Women's height and baseline weight were measured by data collectors, and we obtained weight at the end of the 24th and 36th weeks of gestation from women's medical records. GWG was categorized as inadequate, adequate and excessive based on the United States Institute of Medicine criteria. Predictors of GWG were identified using multinomial logistic regression.

RESULTS

A total of 395 pregnant women were enrolled in the study. GWG was assessed for 369 (93%) women. The median GWG was 8.7 kg with inter quartile ranges (25th, 75th percentiles) of 7.0 kg and 11.6 kg. More than two-third of the participants, 248 (67.2% [95% CI: 62.2, 72.0%]), gained inadequate weight; 103 (27.9% [95% CI: 23.4, 32.8%]) gained adequate weight; and 18 (4.9% [95% CI: 2.9%, 7.6%]) gained excessive weight. Three quarters (75%) of underweight women gained inadequate gestational weight, whereas 43% of overweight or obese women gained inadequate gestational weight. Being underweight (AOR = 3.30 [95% CI: 1.32, 8.24]) or normal weight (AOR = 2.68 [95% CI: 1.37, 5.24]) before pregnancy increased the odds of gaining inadequate gestational weight compared to overweight or obese women. Not having paid employment was associated with higher odds of gaining inadequate gestational weight compared to women employed outside the home (AOR = 2.17 [95% CI: 1.16, 4.07]).

CONCLUSIONS

Most pregnant women in Addis Ababa gain inadequate gestational weight. In particular, three quarters of underweight women gained inadequate gestational weight. Being underweight, normal weight or having no paid employment were associated with higher odds of inadequate GWG. Promoting adequate GWG in Addis Ababa among underweight and normal weight women may be an important public health initiative.

Maternal risk factors and neonatal outcomes associated with low birth weight in a secondary referral hospital in Ghana

INTRODUCTION

Over the past decade, the incidence of low birth weight (LBW) in sub-Saharan Africa has not seen any decline and this is a matter of grave concern for healthcare providers, policymakers, and researchers. Therefore, this study aimed to assess the incidence of LBW and related maternal risk factors (during pregnancy or delivery) as well as neonatal outcomes.

METHODS

An institutional-based retrospective cross-sectional study design was employed to select 1,017 mothers who delivered in the study hospital from January to December 2017 with singleton newborn babies without congenital diseases. Data were analysed using STATA version 14.1 (StataCorp. 2015. Stata Statistical Software: Release 14. College Station, TX: Stata Corp LP). Chi-square test of independence was used to test the association between the dependent variable (LBW) and risk factors of LBW. Bivariate and multivariable unconditional logistic regression was used to determine the factors associated with LBW.

RESULTS

The incidence of LBW was 23.7%. The findings show that being married has a protective effect on LBW [AOR = 0.60 (95%CI: 0.40-0.90), p = 0.013] compared to single mothers. Neonates born between gestational age of 37-42 weeks had 85% lower odds of LBW [AOR = 0.15, (95%CI: 0.10-0.24), p < 0.001)]. Neonates with LBW had a higher risk of low Apgar score in the first minute compared to neonates with normal birth weight [AOR = 0.52 (95%CI: 0.37-0.73), p < 0.001]. Female neonates had 64% higher odds of LBW compared to their male counterparts [AOR = 1.64 (95%CI: 1.19-2.24), p = 0.002].

CONCLUSION

This study revealed a high incidence of LBW. Women's marital status (single mothers), gestational age (<37 weeks), neonatal sex (female), are independent risk factors associated with LBW, while a higher risk of an Apgar score of less than 7 in the first minute was an independent outcome of low birth weight births. The current study findings contribute to the growing literature on the influence of maternal and neonatal factors on LBW in resource-constrained settings. These findings could guide healthcare providers, hospital administrators, stakeholders, and policymakers to develop and implement appropriate clinical and public health strategies aimed at reducing LBW.

Trends of proximate low birth weight and associations among children under-five years of age: Evidence from the 2016 Ethiopian demographic and health survey data

BACKGROUND

Low birth weight puts a newborn at increased risk of death and illness, and limits their productivity in the adulthood period later. The incidence of low birth weight has been selected as an important indicator for monitoring major health goals by the World Summit for Children. The 2014 World Health Organization estimation of child death indicated that 4.53% of total deaths in Ethiopia were due to low birth weight. The aim of this study was to assess trends of proximate low birth weight and associations of low birth weight with potential determinants from 2011 to 2016.

METHODS

This study used the 2016 Ethiopian Demographic and Health Survey data (EDHS) as data sources. According to the 2016 EDHS data, all the regions were stratified into urban and rural areas. The variable "size of child" measured according to the report of mothers before two weeks of the EDHS takes placed. The study sample refined from EDHS data and used for this further analysis were 7919 children. A logistic regression model was used to assess the association of proximate low birth weight and potential determinates of proximate low birth weight. But, the data were tested to model fitness and were fitted to Hosmer-Lemeshow-goodness of fit.

RESULTS

The prevalence of proximate low birth weight in Ethiopia was 26.9% (2132), (95%CI = 25.4, 27.9). Of the prevalence of child size in year from 2011 to 2016, 17.1% was very small, and 9.8% was small. In the final multivariate logistic regression model, region (AOR = xx), (955%CI = xx), Afar (AOR = 2.44), (95%CI = 1.82, 3.27), Somalia (AOR = 0.73), (95%CI = 0.55, 0.97), Benishangul-Gumz (AOR = 0.48), (95%CI = 0.35, 0.67), SNNPR (AOR = 0.67), (95%CI = 0.48, 0.93), religion, Protestant (AOR = 0.76), (95%CI = 0.60, 0.95), residence, rural (AOR = 1.39), (95%CI = 1.07, 1.81), child sex, female (AOR = 1.43), (95%CI = 1.29, 1.59), birth type, multiple birth during first parity (AOR = 2.18), (95%CI = 1.41, 3.37), multiple birth during second parity (AOR = 2.92), (95%CI = 1.86, 4.58), preparedness for birth, wanted latter child (AOR = 1.26), (95%CI = 1.09, 1.47), fast and rapid breathing (AOR = 1.22), (95%CI = 1.02, 1.45), maternal education, unable to read and write (AOR = 1.46), (95%CI = 1.56, 2.17), and maternal age, 15-19 years old (AOR = 1.86), (95%CI = 1.19, 2.92) associated with proximate low birth weight.

CONCLUSIONS

The proximate LBW prevalence as indicated by small child size is high. Region, religion, residence, birth type, preparedness for birth, fast and rapid breathing, maternal education, and maternal age were associated with proximate low birth weight. Health institutions should mitigating measures on low birth weight with a special emphasis on factors identified in this study.

The burden of neonatal sepsis and its association with antenatal urinary tract infection and intra-partum fever among admitted neonates in Ethiopia: A systematic review and meta-analysis

BACKGROUND

More than one-third of the neonatal death in Ethiopia has been attributed to neonatal sepsis. However, there is no recent national evidence about the burden of neonatal sepsis and its association with antenatal urinary tract infection and intra-partum fever, which are commonly reported maternal morbidities in Ethiopia. Therefore, the aim of this systematic review and meta-analysis was to assess the pooled burden of neonatal sepsis and its association with antenatal urinary tract infection as well as intra-partum fever in the country.

METHODS

Primary studies were accessed through Google scholar, HINARI, SCOPUS and PubMed databases. The methodological and evidence quality of the included studies were critically appraised by the modified Newcastle-Ottawa quality assessment tool scale adapted for observational studies. From eligible studies, two authors extracted author/year, study region, study design, sample size, reported prevalence of neonatal sepsis, antenatal urinary tract infection and intrapartum fever on an excel spreadsheet. During critical appraisal and data extraction, disagreements between the two authors were resolved by the involvement of a third author. The extracted data were then exported to stata version 14. Effect sizes were pooled using the random inverse varience-effects model due to significant heterogeneity between studies (I2= 99.2%). Subgroup analysis was performed for evidence of heterogeneity. Sensitivity analyses were performed. Absence of publication bias was declared from symmetry of funnel plot and Egger's test (p = 0.244).

RESULTS

In this systematic review and meta-analysis, a total of 36,016 admitted neonates were included from 27 studies. Of these 27 studies, 23 employed cross-sectional design whereas 3 studies had case control type and only one study had cohort design. The prevalence of neonatal sepsis among admitted Ethiopian neonates at different regions of the country ranged from 11.7%-77.9%. However, the pooled prevalence of neonatal sepsis was 40.25% [95% CI: 34.00%, 46.50%; I2 = 99.2%]. From regional subgroup analysis, the highest prevalence was observed in the Oromiya region. Neonates born to mothers who had antenatal urinary tract infection were at 3.55 times (95% CI: 2.04, 5.06) higher risk of developing neonatal sepsis as compared to those neonates born to mothers who didn't have antenatal urinary tract infection. Moreover, neonates born to mothers having intra-partum fever were 3.63 times (95% CI: 1.64, 5.62) more likely to develop neonatal sepsis as compared to those born to mothers who were nonfebrile during intrapartum.

CONCLUSION

Neonatal sepsis has remained a problem of public health importance in Ethiopia. Both antenatal urinary tract infection and intra-partum fever were positively associated with neonatal sepsis. Therefore, preventing maternal urinary tract infection during pregnancy and optimizing the intra-partum care are recommended to mitigate the burden of neonatal sepsis in Ethiopia.

Spatial distribution and factors associated with low birth weight in Ethiopia using data from Ethiopian Demographic and Health Survey 2016: spatial and multilevel analysis

OBJECTIVE

This study aimed to assess the spatial distribution, individual and community-level factors associated with low birth weight in Ethiopia.

METHOD

Secondary data analysis was conducted using the 2016 Ethiopian Demographic and Health Survey data. A total of 2110 neonates were included in this study. Spatial autocorrelation analysis was conducted to assess the spatial clustering of LBW. Besides, the spatial scan statistics and ordinary kriging interpolation were done to detect the local level clusters and to assess predicted risk areas, respectively. Furthermore, a multilevel logistic regression model was fitted to determine individual and community-level factors associated with LBW. Finally, most likely clusters with log-likelihood ratio (LLR), relative risk and p value from spatial scan statistics and adjusted OR (AOR) with 95% CI for multilevel logistic regression model were reported.

RESULTS

LBW was spatially clustered in Ethiopia. Primary (LLR=11.57; p=0.002) clusters were detected in the Amhara region. Neonates within this spatial window had a 2.66 times higher risk of being LBW babies as compared with those outside the window. Besides, secondary (LLR=11.4; p=0.003; LLR=10.14, p=0.0075) clusters were identified at southwest Oromia, north Oromia, south Afar and southeast Amhara regions. Neonates who were born from severely anaemic (AOR=1.40, 95% CI (1.03 to 2.15)), and uneducated (AOR=1.90, 95% CI (1.23 to 2.93)) mothers, those who were born before 37 weeks of gestation (AOR=5.97, 95% CI (3.26 to 10.95)) and women (AOR=1.41, 95% CI (1.05 to 1.89)), had significantly higher odds of being LBW babies.

CONCLUSION

The high-risk areas of LBW were detected in Afar, Amhara and Oromia regions. Therefore, targeting the policy interventions in those hotspot areas and focusing on the improvement of maternal education, strengthening anaemia control programmes and elimination of modifiable causes of prematurity could be vital for reducing the LBW disparity in Ethiopia.

Low Birth Weight and Associated Factors Among Newborn Babies in Health Institutions in Dessie, Amhara, Ethiopia

Background

Globally, more than 20.5 million infants are born with low birth weight, and the majorities were from Asia and Africa. Even though efforts were made to reduce low birth weight worldwide, it remains a global public health problem, especially in sub-Saharan Africa.

Objective

To assess low birth weight and associated factors among newborn babies in health institutions in Dessie, Amhara, Ethiopia.

Methods

An institution-based cross-sectional study was conducted among 358 newborn/mother pairs from March 1 to April 15, 2017, in Dessie town health institutions. The data were collected using a semi-structured interviewer-guided questionnaire. The numbers of newborn/mother pairs surveyed from each health institution were allocated proportionally, and systematic random sampling was used to select the respondents. Epi-info version 7.0 was used for data entry, and Statistical Package for Social Sciences version 20 was used for the analysis. Multivariate logistic regression with adjusted odds ratios and 95% confidence intervals were used to identify significantly associated variables with low birth weight.

Results

In this study, the prevalence of low birth weight was 15.6%. Maternal age <20 years (AOR: 3.78, 95% CI, 1.02–13.97), rural residence (AOR: 3.49, 95% CI, 1.48–8.24), having antenatal care follow-up (AOR: 3.79, 95% CI, 1.08–13.23), gestational age <37 weeks (AOR: 3.82, 95% CI, 1.55–9.42), and females (AOR: 3.37, 95% CI, 1.17–9.72) were significantly associated with low birth weight.

Conclusion

The proportion of LBW in this study is comparable to the estimated global prevalence. Maternal age, residence, antenatal care, gestational age, and sex were significantly associated variables with low birth weight. Therefore, special attention should be given to antenatal care services and preventive strategies for preterm delivery.

The impact of pregnancy induced hypertension on low birth weight in Ethiopia: systematic review and meta-analysis

Background

Even though neonatal mortality reduction is the major goal needed to be achieved by 2030, it is still unacceptably high especially in Ethiopia. In the other hand, low birth weight is the major cause of neonatal mortality and morbidity. More than 10 millions of low birth weight infants occurred as a result of pregnancy induced hypertension. However, in Ethiopia the association between low birth weight and pregnancy induced hypertension was represented with un-updated, inconclusive and different studies. Therefore, this review aimed to estimate the overall pooled impact of pregnancy induced hypertension on low birth weight and its association in Ethiopia.

Methods

articles searched on PubMed/Medline, EMBASE, CINAHL, Cochrane library, Google, Google Scholar and local shelves. Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI) was applied for critical appraisal. The I² statistic was computed to check the presence of heterogeneity. Publication bias was evaluated using funnel plot asymmetry and Egger’s test. A random effect model was used to estimate the pooled prevalence of low birth weight.

Result

From the total 131 identified original articles, 25 were eligible and included for the final analysis. The overall pooled prevalence of low birth weight among women who had pregnancy induced hypertension in Ethiopia was 39.7% (95% CI: 33.3, 46.2). But, I² statistic estimation evidenced significant heterogeneity across included studies (I² = 89.4, p < 0.001). In addition, the odds of having low birth weight newborns among women who had pregnancy induced hypertension was 3.89 times higher compared to their counterparts (OR = 3.89, 95% CI: 2.66, 5.69).

Conclusion

The pooled prevalence of low birth weight among women who had pregnancy induced hypertension was more than two times higher than the pooled estimate of low birth weight among all reproductive aged women. The odds of low birth weight also increased nearly four times among women with pregnancy induced hypertension than normotensive women. Therefore, health policies which provide better and quality antenatal care with more oriented on importance of early detection and management of pregnancy induced hypertension should be implemented.

Women's autonomy in healthcare decision-making and healthcare seeking behaviour for childhood illness in Ghana: Analysis of data from the 2014 Ghana Demographic and Health Survey

INTRODUCTION

The capacity of women to decide on their healthcare plays a key role in their health. In this study, we examined the association between women's healthcare decision-making capacity and their healthcare seeking behaviour for childhood illnesses in Ghana.

MATERIALS AND METHODS

We used data from the 2014 Ghana Demographic and Health Survey. A total sample of 2,900 women with children less than 5 years was used for the analysis. Data were processed and analysed using STATA version 14.0. Chi-square test of independence and binary logistic regression were carried out to generate the results. Statistical significance was pegged at 95% confidence intervals (CIs). We relied on the 'Strengthening the Reporting of Observational Studies in Epidemiology' (STROBE) statement in writing the manuscript.

RESULTS

Out of the 2,900 women, approximately 25.7% could take healthcare decisions alone and 89.7% sought healthcare for childhood illnesses. Women who decided alone on personal healthcare had 30% reduced odds of seeking healthcare for childhood illnesses compared to those who did not decide alone [AOR = 0.70, CI = 0.51-0.97]. With age, women aged 45-49 had 69% reduced odds of seeking healthcare for childhood illnesses compared to those aged 25-29 [AOR = 0.31, CI = 0.14-0.70]. Women from the Northern and Upper West regions had 72% [AOR: 0.28, CI: 0.11-0.70] and 77% [AOR: 0.23, CI: 0.09-0.58] reduced odds of seeking healthcare for childhood illnesses respectively, compared to those from the Western region.

CONCLUSION

Ghanaian women with autonomy in healthcare decision-making, those who were older and those from the Northern and Upper West regions were less likely to seek healthcare for childhood illness. To reduce childhood mortalities and morbidities in Ghana, we recommend educating women such as those who take healthcare decisions alone, older women and women from deprived regions like the Northern and Upper West regions on the need to seek healthcare for childhood illnesses.

The association between intimate partner violence and low birth weight and preterm delivery in eastern Ethiopia: Findings from a facility-based study

OBJECTIVE

To determine the associations between intimate partner violence during pregnancy and low birth weight and preterm birth among women who gave birth in public hospitals in Harari region, eastern Ethiopia.

DESIGN

A cross-sectional study was conducted among women who gave birth in public hospitals in Harari region.

PARTICIPANTS

Women aged 16-45 years who gave birth in hospitals from November 2018 to April 2019.

SETTING

Two public hospitals in Harari regional state, eastern Ethiopia MEASUREMENT: Intimate partner violence was measured using a questionnaire adapted from the World Health Organization Multi-Country Study on Women's Health and Domestic Violence against Women. Binary and multiple logistic regression was performed to establish the association between intimate partner violence and low birth weight and preterm birth. Both crude and adjusted odds ratios with 95% confidence intervals were calculated. The level of significance was set at a p-value of <0.05.

RESULTS

In this study, 39% of women reported experiencing partner violence during their most recent pregnancy. The prevalence of preterm birth and low birth weight were found to be 18.9% and 12.01%, respectively. After adjusting for potential confounders, women who experienced any intimate partner violence during pregnancy were 1.62 times (AOR = 1.62, 95%CI= 1.22, 2.78) more likely to give birth prematurely and 1.37 times (AOR= 1.37, 95%CI=1.73, 2.57) more likely to have a low birth weight infant relative to women who did not experience intimate partner violence during pregnancy.

CONCLUSION AND IMPLICATIONS FOR PRACTICE

The results underscore the need for including intimate partner violence prevention as an important strategy to reduce child mortality and morbidity. Screening pregnant women for intimate partner violence and providing support for women who have experienced violence might be helpful in tackling prematurity and low birth weight.

Incidence of postpartum and neonatal illnesses and utilization of healthcare services in rural communities in southern Ethiopia: A prospective cohort study

Although improving postpartum and neonatal health is a key element of the Ethiopian health extension program, the burdens of postpartum and neonatal illnesses and healthcare-seeking in rural communities in Ethiopia are poorly characterized. Therefore, we aimed to assess the incidence and risk factors for these illnesses and measure the utilization of healthcare services. We conducted a prospective cohort study of 784 postpartum women and their 772 neonates in three randomly selected kebeles in rural southern Ethiopia. Eight home follow-up visits were conducted during the first 42 postpartum days, and six neonate follow-ups were conducted at the same home over the first 28 days of life. The Prentice, Williams, and Peterson’s total time Cox-type survival model was used for analysis. We recorded 31 episodes of postpartum illness per 100 women-weeks (95% confidence interval [CI]: 30%, 32%) and 48 episodes of neonatal illness per 100 neonate-weeks (95% CI: 46%, 50%). Anemia occurred in 19% of women (95% CI: 17%, 22%) and low birth weight (<2,500g) in 15% of neonates (95% CI: 13%, 18%). However, only 5% of postpartum women (95% CI: 4%, 7%) and 4% of neonate (95% CI: 3%, 5%) reported utilizing healthcare services. Walking over 60 minutes to access healthcare was a factor of both postpartum illnesses (AHR = 2.61; 95% CI: 1.98, 3.43) and neonatal illnesses (AHR = 2.66; 95% CI: 2.12, 3.35)). Birth weight ≥2500g was identified factor of neonatal illnesses (AHR = 0.39; 95% CI: 0.33, 0.46). Compared with younger mothers, older mothers with sick newborns (AHR = 1.22; 95% CI: 1.00, 1.50) or postpartum illnesses (AHR = 1.40; 95% CI: 1.03, 1.89) were more likely to seek healthcare. Reasons for not utilizing healthcare services included a belief that the illnesses were not serious or would resolve on their own, little confidence in the healthcare institutions, and the inability to afford the cost. The burden of postpartum and neonatal illnesses in rural communities of southern Ethiopia remains high. Unfortunately, few participants utilized healthcare services. We recommend strengthening the health system that enables identifying, managing, treating, and referring maternal and neonatal illnesses and provide reasonable healthcare at the community level.

Prevalence and Associated Factors of Low Birth Weight among Term Newborns in Dilla Town, Southern Ethiopia

Introduction

Birth weight has emerged as the pointer of infant wellbeing and the fundamental focus of infant health policy. Low birth weight predisposes newborns to loads of health disarray like underweight, stunting, hypoglycemia, hypothermia, mental retardation, physical, and neurodevelopment problems which results in high rates of morbidity and mortality. This study aimed to assess the prevalence and associated factors of low birth weights in term newborns.

Objective

This study designed to assess the prevalence and associated factors of low birth weight among term newborns in Dilla town, Southern Ethiopia.

Materials and Methods

Institutional based cross-sectional study design was used on 472 term newborns. The study setting includes three health centers (Dilla, Wallemi, and Tumetecha) within Dilla town and Dilla University referral hospital from September 1, 2018, to January 30, 2019. The study subjects were mothers with term newborns delivered in the above institutions and those delivered at home and received care within the first 24 hours after delivery in the above health care settings.

Results

A total of 161 (34.1%) of the term newborns were low birth weight. Divorced mothers, rural residents, maternal age <20 years old, unwanted and unintended pregnancy, no ANC follow-up, no dietary counsel, no foliate supplementation, and cigarette smoking have shown an association with low birth weight of neonates.

Conclusions

Even though the method of sampling used in this study has its confines, the prevalence of low birth weight in this study was higher than the estimate in Ethiopia. Therefore, it is recommended that special attention should be given to pregnant mothers to get adequate rest, additional diet, and antenatal services available and accessible to all pregnant women.

Level of physical activity and other maternal characteristics during the third trimester of pregnancy and its association with birthweight at term in South Ethiopia: A prospective cohort study

Birthweight continues to be the leading infant health indicator and the main focus of infant health policy. Low birthweight babies are at a higher risk of mortality and morbidity in most low-income countries. However, the physical activity level of pregnant women and its association with low birthweight is not well studied in Ethiopia. To address the above gap, we aimed to examine the maternal physical activity level and other characteristics during the third trimester and its association with birthweight at term in South Ethiopia. A community-based prospective cohort study was conducted among 247 randomly selected women in their third trimester of pregnancy. We measured the physical activity level using the Global Physical Activity Questionnaire, which included the type and level of various categories of activities. Anthropometric measurements of mothers were taken following standard procedures, and birthweight was recorded within 72 hours of delivery. To identify the effect of physical activity level and other maternal characteristics on low birthweight, we performed a multivariable logistic regression analysis. Overall, 111 (47.2%) mothers were engaged in vigorous physical activities during third trimester. The incidence of low birthweight was 21.6% and 9.68% among newborns of mothers who engaged in vigorous and moderate or low physical activity, respectively. The incidence of low birthweight at term was significantly associated with vigorous physical activity [adjusted odds ratio (AOR) = 2.48; 95% confidence interval (CI): 1.01–6.09], prolonged standing [AOR = 3.37; 95% CI: 1.14–9.93], and squatting [AOR = 2.61; 95% CI: 1.04–6.54)] during the third trimester of pregnancy. The vast majority of pregnant women were engaged in vigorous physical activities in their third trimester. Engagement in vigorous physical activity, standing for longer hours, and squatting were the major contributors to low birthweight at term. Hence, focused counseling should be conducted to reduce vigorous physical activity, standing, and squatting during the third trimester among pregnant women.

Predictors of low birth weight and preterm birth in rural Uganda: Findings from a birth cohort study

BACKGROUND

Approximately 20.5 million infants were born weighing <2500 g (defined as low birthweight or LBW) in 2015, primarily in low- and middle-income countries (LMICs). Infants born LBW, including those born preterm (<37 weeks gestation), are at increased risk for numerous consequences, including neonatal mortality and morbidity as well as suboptimal health and nutritional status later in life. The objective of this study was to identify predictors of LBW and preterm birth among infants in rural Uganda.

METHODS

Data were derived from a prospective birth cohort study conducted from 2014-2016 in 12 districts across northern and southwestern Uganda. Birth weights were measured in triplicate to the nearest 0.1 kg by trained enumerators within 72 hours of delivery. Gestational age was calculated from the first day of last menstrual period (LMP). Associations between household, maternal, and infant characteristics and birth outcomes (LBW and preterm birth) were assessed using bivariate and multivariable logistic regression with stepwise, backward selection analyses.

RESULTS

Among infants in the study, 4.3% were born LBW (143/3,337), and 19.4% were born preterm (744/3,841). In multivariable analysis, mothers who were taller (>150 cm) (adjusted Odds Ratio (aOR) = 0.42 (95% CI = 0.24, 0.72)), multigravida (aOR = 0.62 (95% CI = 0.39, 0.97)), or with adequate birth spacing (>24 months) (aOR = 0.60 (95% CI = 0.39, 0.92)) had lower odds of delivering a LBW infant Mothers with severe household food insecurity (aOR = 1.84 (95% CI = 1.22, 2.79)) or who tested positive for malaria during pregnancy (aOR = 2.06 (95% CI = 1.10, 3.85)) had higher odds of delivering a LBW infant. In addition, in multivariable analysis, mothers who resided in the Southwest (aOR = 0.64 (95% CI = 0.54, 0.76)), were ≥20 years old (aOR = 0.76 (95% CI = 0.61, 0.94)), with adequate birth spacing (aOR = 0.76 (95% CI = 0.63, 0.93)), or attended ≥4 antenatal care (ANC) visits (aOR = 0.56 (95% CI = 0.47, 0.67)) had lower odds of delivering a preterm infant; mothers who were neither married nor cohabitating (aOR = 1.42 (95% CI = 1.00, 2.00)) or delivered at home (aOR = 1.25 (95% CI = 1.04, 1.51)) had higher odds.

CONCLUSIONS

In rural Uganda, severe household food insecurity, adolescent pregnancy, inadequate birth spacing, malaria infection, suboptimal ANC attendance, and home delivery represent modifiable risk factors associated with higher rates of LBW and/or preterm birth. Future studies on interventions to address these risk factors may be warranted.
