Determinants of prenatal anemia in Ethiopia

Short birth interval prevalence, determinants and effects on maternal and child health outcomes in Asia-Pacific region: a systematic review and meta-analysis protocol

BACKGROUND

Short birth interval (SBI) has been linked to an increased risk of adverse maternal, perinatal, infant and child health outcomes. However, the prevalence and maternal and child health impacts of SBI in the Asia-Pacific region have not been well understood. This study aims to identify and summarise the existing evidence on SBI including its definition, measurement prevalence, determinants and association with adverse maternal and child health outcomes in the Asia-Pacific region.

METHODS

Five databases (MEDLINE, Scopus, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Maternity and Infant Care, and Web of Science (WoS)) will be systematically searched from September 2000 up to May 2023. Data will be extracted, charted, synthesised and summarised based on the outcomes measured, and where appropriate, meta-analysis will be performed. The risk of bias will be assessed using Joanna Briggs Institute quality appraisal. Grading of Recommendation Assessment, Development and Evaluation framework will be used to evaluate the quality of cumulative evidence from the included studies.

Anemia Prevalence and Risk Factors in Two of Ethiopia's Most Anemic Regions among Women: A Cross-Sectional Study

Background

In Sub-Saharan African (SSA) nations, including Ethiopia, anemia is a significant public health issue. Ethiopia has continued to bear the enormous burden of anemia infections. Over time, the prevalence of anemia has significantly increased in Ethiopia. In addition, there is a paucity of literature and regional variations in the pace of increment expansion. Therefore, the primary goal of this study was to evaluate the prevalence of anemia and risk factors among women in Ethiopia's two most anemic regions.

Methods

2,519 women participated in a community-based cross-sectional study from January 18 to June 27, 2016. In order to determine the causes of anemia in women in two of Ethiopia's most anemic regions, an ordinal logistic regression model was taken into consideration. The applicability of the proportional odds test was evaluated using the chi-square test of the parallelism assumption. A p value of 0.05 or below was used to define crucial and statistically significant predictor variables.

Results

The overall prevalence rate of anemia was 56.8% (95% CI (54.8%-58.7%)). The chi-square test of the parallelism assumption indicated that the odds ratios were constant across all cut-off points of women's anemia levels at a 5% significance level (p value = 0.122). Of the severity of anemia levels among women, 48.2, 46.1, and 5.7% had mild, moderate, and severe anemia levels, respectively. In multivariable ordinal logistic regression analyses, being born (lived) in the Somali region (AOR = 1.6, 95% CI: 1.37, 1.90), having a parity of 4-5 (AOR = 1.3, 95% CI: 1.05, 1.66), and having ≥6 children (AOR = 1.4, 95% CI: 1.1, 1.7), being a contraceptive user (AOR = 3, 95% CI: 2.5, 3.6), being currently pregnant (AOR = 2.8, 95% CI: 2.3, 3.4), having no ANC follow-up (AOR = 1.9, 95% CI: 1.6, 2.3), being married women (AOR = 1.4, 95% CI: 1.1, 1.9), and user of unimproved toilet facility (AOR = 1.3, 95% CI: 1.1, 1.6) were significantly positively associated with anemia.

Conclusions

Finally, the anemia burden was dangerously greater than the national average. The region, usage of contraceptives, being pregnant at the time, ANC follow-up, toilet facilities, parity, and marital status all had a substantial impact on anemia. Therefore, to lessen the prevalence of anemia in certain parts of Ethiopia, public health initiatives that improve maternal health service utilization are required, such as ANC follow-up to minimize parity.

Geospatial disparities and predictors of anaemia among pregnant women in Sub-Saharan Africa

BACKGROUND

Anaemia has become a major public health concern among women in Sub-Saharan Africa (SSA). However, little is known about the spatial disparities in anaemia prevalence and their associated factors among pregnant women in the region. This study analysed the spatial disparities in anaemia and their associated factors among pregnant women in rural and urban settings in SSA.

METHODS

This is a secondary analysis of the most recent demographic and health surveys of 26 countries in SSA. Spatial autocorrelation and hotspot assessment were conducted, while a multivariate logistic regression model was used to identify demographic factors associated with anaemia.

RESULTS

Anaemia was reported among ~50% of pregnant women in urban and rural areas of SSA. The hotspot analysis identified the West African sub-region as having a higher concentration of anaemia cases in rural settings. In urban areas, the odds of anaemia were significantly higher among pregnant women in their second trimester (Adjusted OR = 2.39, CI = 1.99, 2.76). On the other hand, pregnant women in their third trimester (Adjusted OR = 1.98, CI = 1.77, 2.22) and those who had taken intestinal parasite drugs (Adjusted OR = 1.12 CI = 1.02, 1.23) had a higher likelihood of having anaemia in rural areas. Pregnant women aged 35-39 years (Adjusted OR = 0.52, CI = 0.33, 0.81) and those aged 40-44 years (Adjusted OR = 0.69, CI = 0.50, 0.95) had a lesser likelihood of having anaemia compared to women aged 15-19 years in urban and rural areas respectively. Compared to Congo DR, Benin (OR = 2.22, CI = 1.51, 3.28) and Mali (OR = 3.71, CI = 2.73, 5.05) had higher odds of anaemia in urban and rural areas respectively.

CONCLUSIONS

Spatial disparities in anaemia persist among pregnant women in rural and urban settings in SSA. Prevailing spatial variations in anaemia may be addressed by specialised interventions considering the contextual residential settings and socio-economic factors highlighted in this study.

Understanding the traditional values and use of okra among pregnant women in western Ethiopia: a qualitative study

OBJECTIVES

This study explored the traditional values and use of okra among pregnant women, how okra plants are obtained, prepared and used by pregnant women, and the associated beliefs and meanings attached to it in western Ethiopia.

DESIGN

Qualitative research.

SETTING

Rural areas of western Ethiopia.

PARTICIPANTS

A purposive sampling technique was used to select a total of 86 pregnant women (14 for in-depth interviews and 72 for focus group discussions) in western Ethiopia.

RESULTS

Traditionally okra is used as a source of income and is a common food for guests visiting homes. In line with this, pregnant women in the western part of Ethiopia mainly consumed okra pods. For future consumption and preservation for a long period, they usually transform okra into powder.

CONCLUSIONS

Other parts of the okra plant rather than pods are not known as a food source and are the most neglected food sources in rural districts of western Ethiopia. The study provides evidence that supports nutritional behavioural change communication interventions on promoting the utilisation of different parts of okra and awareness creation on the nutritional values of okra.

Effect of Schooling on Anemia and Nutritional Status Among Women: A Natural Experiment in Ethiopia

This study estimates the effect of length of schooling on anemia and nutritional status and evaluates the cost-effectiveness of primary schooling as an anemia intervention for women of childbearing age in Ethiopia. In 1994-1995, Ethiopia abolished primary school tuition fees and embarked on a large-scale educational investment program, which increased primary school enrollment and retention. An instrumented regression-discontinuity design was used to examine the effect on anemia risk and body mass index (BMI) of an increase in length of schooling resulting from the reforms, as a natural experiment. Anemia and BMI biomarkers and demographic data for 13,984 women were obtained from the 2011 and 2016 Ethiopia Demographic and Health Surveys, with the 2019 Mini Demographic and Health Survey used for robustness checks. Results indicate that each additional year of schooling reduced anemia risk by 3 percentage points (9.2%-11.2% reduction) and increased BMI (weight (kg)/height (m)2) by 0.26-0.42. Primary education was cost-effective-based on World Health Organization cost-effectiveness thresholds-as an anemia intervention, with a cost per anemia case averted of US$1,654. The findings suggest that investment in education reduces anemia risk later in life.

Interbirth interval and maternal anaemia in 21 sub-Saharan African countries: A fractional-polynomial analysis

Background

Maternal anaemia is a global public health problem contributing to adverse maternal and perinatal outcomes. In addition to other risk factors, interbirth interval has been identified as a potentially modifiable risk factor of maternal anaemia. However, the current evidence for the association between interbirth interval and maternal anaemia remains inconclusive. Hence, this study examined the association between the interbirth interval and maternal anaemia in sub-Saharan Africa.

Methods

We conducted a multinational cross-sectional study of interbirth interval (time between two singleton live births) and maternal anaemia (haemoglobin levels < 12 g/dl for non-pregnant women, < 11 g/dl for pregnant women) for 21 sub-Saharan African countries using the most recent nationally representative Demographic and Health Surveys, 2010–2017. A weighted multivariable fractional polynomial function was used to estimate the non-linear relationship between interbirth interval and maternal anaemia, considering interbirth interval as a continuous variable and adjusting for potential confounders. Analyses were stratified by reproductive classification (non-pregnant and pregnant women).

Results

There were 81,693 women included in the study (89.2% non-pregnant, 10.8% pregnant). Of all women, 32.2% were in their postpartum period. Overall, 36.9% of women had anaemia (36.0% of non-pregnant and 44.3% of pregnant women). Of the participants, 15% had a short interbirth interval (<24 months), and 16% had a long interbirth interval (≥ 60 months). We found that both short and longer interbirth intervals were associated with an increased risk of maternal anaemia in a dose-response fashion. Relatively a lower risk of maternal anaemia was observed between 24 and 40 months of interbirth intervals.

Conclusions

Our findings suggest that both short and longer interbirth intervals were associated with an increased risk of maternal anaemia in sub-Saharan Africa.

Preconception care utilization and associated factors among reproductive age women in Mizan-Aman town, Bench Sheko zone, Southwest Ethiopia, 2020. A content analysis

Background

Preconception care is highly important in reducing a number of adverse pregnancy outcomes and helps to improve maternal health. Preconception care optimizes women’s health and improves pregnancy outcomes. It is a cost-effective first-line preventive strategy for birth defects. However, preconception care utilization in Ethiopia was very low. Studies on these issues are limited in Ethiopia in general and in Mizan-Aman town in particular.

Objective

To assess preconception care utilization and associated factors among reproductive age women in Mizan-Aman town, Bench-Sheko Zone, Southwest Ethiopia.

Methods

A community based cross-sectional study design was employed from April 16 to May 26, 2020 in Mizan-Aman town. The total study participants were 624 reproductive age women. Data were collected by using pre-tested interviewer administered questionnaires and entered into Epi-data version 3.1 then exported to STATA version 14 and analyzed accordingly. Univeriate and Bivariable analysis was done by analysis of variance (ANOVA) and independent t-test. Multivariable statistical analysis using generalized linear regression model (GLM) approach was used to classify factors of preconception care utilization. Since our response variable is measured in terms of count variable, we used a Poisson regression model with a log link function. Finally, Statistical significance between dependent and independent variables were assessed by odds ratios and 95% confidence intervals.

Results

Overall, 28.6% of the women receipt atleast one item of preconception care while only 1.5% were taken the whole recommended components of preconception care services. The most common item received in the study area was taking micronutrient supplementation (18.5%). Age of women, educational status, husbands educational status, husbands occupation, wealth status, distance from the health facility, waiting time to get services, planning to pregnancy, age at first pregnancy, previous ANC use, Previous PNC use, adverse pregnancy experience, women’s knowledge of preconception care, and attitude on preconception care were determinants of preconception service utilization.

Conclusions

Preconception care component utilization was lower as compare with recommended service with different disparities. Multipurpose tailored strategies which incorporate a woman with no formal education, poor knwledge on preconception care,never take maternal services previously and distant from health facility could improve preconception care service utilization. Advocative strategies on preconception care component and planning pregnancy may elicite more women to use the services of preconception care.

Maternal anemia and baby birth size mediate the association between short birth interval and under-five undernutrition in Ethiopia: a generalized structural equation modeling approach

Background

Studies assessing the association between short birth interval, a birth-to-birth interval of less than 33 months, and under-five undernutrition have produced inconclusive results. This study aimed to assess the relationship between short birth interval and outcomes of stunting, underweight, and wasting among children aged under-five in Ethiopia, and potential mediation of any associations by maternal anemia and baby birth size.

Method

Data from the 2016 Ethiopia Demographic and Health Survey (EDHS) was used. Stunting, wasting, and underweight among children aged under-five were outcome variables. Generalized Structural Equation Modeling (GSEM) was used to examine associations between short birth interval and outcomes, and to assess hypothesized mediation by maternal anemia and baby birth size.

Results

Significant associations between short birth interval and stunting (AOR = 1.49; 95% CI = 1.35, 1.66) and underweight (AOR = 1.43; 95% CI = 1.28, 1.61) were found. There was no observed association between short birth interval and wasting (AOR = 1.05; 95% CI = 0.90, 1.23). Maternal anemia and baby birth size had a significant partial mediation effect on the association between short birth interval and stunting (the coefficient reduced from β = 0.337, p < 0.001 to β = 0.286, p < 0.001) and underweight (the coefficient reduced from β = 0.449, p < 0.001 to β = 0.338, p < 0.001). Maternal anemia and baby birth size mediated 4.2% and 4.6% of the total effect of short birth interval on stunting and underweight, respectively.

Conclusion

Maternal anemia and baby birth size were identified as mediators of the association between short birth interval and under-five undernutrition status. Policies and programs targeting the reduction of under-five undernutrition should integrate strategies to reduce maternal anemia and small baby birth size in addition to short birth interval.

Anemia among pregnant women in internally displaced camps in Mogadishu, Somalia: a cross-sectional study on prevalence, severity and associated risk factors

BACKGROUND

Anemia in pregnancy is a serious global public health problem in most developing countries and a major cause of maternal morbidity and mortality. Somalia which already had very high maternal mortality ratio of 829 per 100,000 live births, pregnant women in internally displaced camps (IDPs) remain at most exposed. The aim of the study was to determine the prevalence, severity and associated risk factors of anemia among pregnant women in internally displaced camps in Mogadishu, Somalia.

METHODS

A community based cross-sectional study was conducted among 383 households in the most IDP settled districts in Mogadishu. Every pregnant mother in these sampled households who was voluntarily consented was targeted. A sample of blood was also taken by pricking the fingertip and inserted into hemoglobin meter. Those with Hb < 11 g/dl from hemoglobin meter had been taken another sample of 3 cc blood and put into EDTA tube for CBC analysis to identify the type of anemia. Data on risk factors were collected using structured pretested questionnaire via an interview. Collected data was coded and entered in SPSS- Version 22 for analysis. Descriptive analysis, bivariate chi-square and multivariate logistic regression were done.

RESULTS

The overall prevalence of anemia among study participants was 44.4% (95%CI: 39.5-49.3%), where severe and moderate anemia were 11.8 and 47.0% respectively. In addition all anaemic cases were microcytic hypochromic anemia. Young maternal age, low Family income, fewer/zero parity, being at third or second trimesters, lack of ANC attendance during pregnancy, lack of iron supplementation during pregnancy, taking tea immediately after meal during pregnancy, lower/zero frequency of daily meat and vegetables consumption during pregnancy were associated risk factors of anemia.

CONCLUSION

The anemia prevalence from this study was severe public health problem. Several factors were found to be associated with anemia during pregnancy. Measures has to be taken to curb the problem by including them mass iron supplementation and health education towards identified risk factors.

Nutritional and Obstetric Determinant of Iron Deficiency Anemia among Pregnant Women Attending Antenatal Care Services in Public Health Hospitals in Abidjan (Côte d'Ivoire): A Cross-Sectional Study

Poorly diversified and micronutrient-deficient dietary intakes during pregnancy remain one of the major causes of nutritional anemia in developing countries. However, data on diet and its relation to anemia in pregnant women in Côte d'Ivoire are scarce. The objective of this study was to determine prevalence and iron deficiency anemia associated factors in pregnant women in Abidjan. A cross-sectional study was conducted among 389 pregnant women attending antenatal care services at public health hospitals in Abidjan. Sociodemographic, obstetrical, and dietary data were collected. Blood samples taken by venipuncture were analyzed for hemoglobin and iron biomarkers. Data were subjected to descriptive statistics and multivariate logistic regression. 47.8% of the pregnant women tested were anemic, 25.8% and 30.4% had iron deficiency and iron deficiency anemia, respectively. Based on AORs, the second and third trimesters of pregnancy (6.04 v 4.18, respectively), multiparity (13.18), skipping meals (3.05), inadequate energy (5.369), protein (2.74), and vitamin C (2.43) intakes and low dietary diversity (8.35) are the independent and significant determinants of iron deficiency anemia. The high prevalence of anemia among pregnant women in Abidjan reveals a real public health problem. Iron deficiency anemia is due to multiparity, gestational age, inadequate intake, low dietary diversity, and skipping meals.

Prevalence of Anemia and Associated Factors Among Term Newborns in Nekemte Specialized Hospital, Western Ethiopia

Background

Anemia is a global public health problem that affects approximately one-third of the global population. Infants and children are the ones to develop both short-term and long-term devastating complications from anemia. Although anemia is a very big public health concern, newborns, especially in developing countries, are usually overlooked and undiagnosed.

Purpose

The aim of this study was to assess the prevalence of anemia and associated factors among term newborns in Nekemte Specialized Hospital, Western Ethiopia.

Methods

A facility-based cross-sectional study involving 278 newborns was conducted from October to November, 2020 with an interview-based questionnaire that included maternal socio-demographic and obstetrics characteristics, newborn’s weight and sex. The data were analyzed with SPSS version 20. The prevalence of newborn anemia was shown in percentage and as a pie-chart. Bivariate analysis and binary logistic regression were used to identify the predictors of anemia in the term newborn.

Results

The overall prevalence of newborn anemia in the hospital was 29.1%. Maternal anemia (AOR: 3.95, 95% C.I.: 1.97–7.92), delivery by cesarean section (AOR: 4.17, 95% C.I.: 1.89–9.20), vaginal bleeding during pregnancy (AOR: 5.43, 95% C.I.: 1.60–18.39), and maternal failure to take iron-folate supplements during pregnancy (AOR: 2.17, 95% C.I.:1.07–4.41) were factors associated with newborn anemia.

Conclusion

Anemia among newborns in the hospital was a moderate public health problem. Policy makers should consider maternal health education and appropriate health interventions to reduce the problem. In addition, further longitudinal studies are needed to identify specific causes of newborn anemia in order to prevent the possible complications.

Socio-economic determinants of prenatal anaemia in rural communities of South-West Nigeria: a preliminary report

BACKGROUND

Anaemia is common worldwide and pregnant women are one of the most vulnerable group. Although, anaemia in the general population including pregnant women is multi-factorial in aetiology, the most frequent cause in pregnancy worldwide is iron deficiency. In Nigeria, an estimated prevalence of anaemia among pregnant women ranges from 35-75%. Anaemia in pregnancy (AIP) is associated with significant perinatal and maternal morbidity and mortality including premature birth and low birth weight.

AIM

The aim of this study was to determine the prevalence, demographic and socio-economic determinants of anaemia in pregnancy in a rural community of South-West Nigeria.

MATERIALS AND METHODS

One-hundred and fifty consenting pregnant women aged 18-42 years in the three trimesters were recruited from four primary health centres of Ikene Local Government of Ogun State of Nigeria after ethical approval was obtained from the Ethics Unit of the Medical officer of Health of the Local Government. Pre-tested interviewer-administered questionnaire was used to collect data on socio-demographic information and 24-hour dietary recall. Using a finger prick, the haemoglobin concentration of each respondent was determined with a haemoglobinometer (DG-300HB manufactured by DouBle, China). Data was analyzed using the Statistical Package for Social Sciences (SPSS) version 20.

RESULTS

All the respondents belonged to low socio-economic class. The mean haemoglobin (Hb) concentration obtained in this study was 10.22±1.60 g/dL with a range of 6-14.8 g/dL. Using WHO cut-off Hb concentration of 11 g/dL, the prevalence of anaemia in this study was 67.3%. The frequency of anaemia increased with increase in age group. P=0.010. About 21.4% of those with adequate dietary iron intake were anaemic when compared with 72.1% (98 of 136) of those with inadequate dietary iron intake who were anaemic. AOR-0.090; 95% CI- 0.018-0.457; P=0.004.

CONCLUSION

Increasing age, low socio-economic status, poor health education and low dietary iron intake were the predominant socio-economic determinants of prenatal anaemia in the population studied. Efforts must be intensified to alleviate poverty in rural areas and give health education on iron-rich foods to girls and women of children-bearing age in the rural communities.

Hemoglobin Level and Associated Factors among Pregnant Women in Rural Southwest Ethiopia

Background

Anemia is a situation in which the number and size of red blood cells, or the concentration of hemoglobin, fall below established cut-off values. Low hemoglobin level during pregnancy favors the alteration of placental angiogenesis and resulted in restricting the availability of nutrients to the fetus and consequently causing fetal growth retardation and low weight at birth. This study is aimed at assessing the hemoglobin level and associated factors among pregnant women in rural communities of Jimma zone, Southwest Ethiopia.

Methods

A community-based cross-sectional study design was carried out among 367 pregnant women from June 1 to 30, 2020. Systematic random sampling was used to select study subjects. Hemoglobin level was measured by using HemoCue HB 301. An interviewer-administered structured questionnaire was used to collect the data. Descriptive statistics were used to describe the study subjects. A multivariable linear regression model was employed after the linearity, normality, multicollinearity, and homoscedasticity assumptions were checked. The unstandardized beta (β) coefficient along with a 95% confidence interval was computed to estimate the association between explanatory and dependant variables. Statistical significance was declared at P value < 0.05.

Results

The mean (± SD) hemoglobin level of the respondents was 12.66 (±1.44) g/dl. The overall magnitude of anemia (hemoglobin level < 11 g/dl) among pregnant women was found to be 85 [23.16%, (95% CI: 18.3%-27.5%)]. Meal frequency [β = 0.40, (95% CI: 0.12, 0.69), P = 0.005], interpregnancy interval [β = 0.08, (95% CI: 0.02, 0.15), P = 0.007], mid-upper arm circumference measurement [β = 0.13, (95% CI: 0.07, 0.20), P ≤ 0.001], own fruits/vegetable [β = 0.55, (95% CI: 0.79, 0.31), P ≤ 0.001], coffee consumption [β = −1.00, (95% CI: -1.31, -0.68), P ≤ 0.001], and having history of still birth [β = −0.63, (95% CI: -1.06, -0.20), P = 0.004] were significantly associated with the hemoglobin level of pregnant women.

Conclusions

Anemia was identified to be a moderate public health problem in the study area. Therefore, nutritional counseling should focus on the necessity of at least one extra meal, promotion of fruits/vegetable consumption, and improving the nutritional status of the women during antenatal care follow-up. Moreover, early screening and management of women with a history of stillbirth for anemia are also essential.

Child Caregiver's healthcare seeking behavior and its determinants for common childhood illnesses in Addis Ababa, Ethiopia: a community-based study

BACKGROUND

Appropriate healthcare-seeking behavior and access to the health care facility is key to improving health service utilization. Although the accessibility of comprehensive childhood disease intervention services in Ethiopia has been modified at the community level, the use of such health care services has remained limited. Therefore, this study aimed to assess the healthcare-seeking behavior of common childhood illness and its determinants.

METHODS

A community-based cross-sectional study design was used. A multi-stage sampling method was used to recruit eight hundred and thirty-four study participants. A pre-tested and standardized questionnaire was used to collect data. The collected data were visually checked for incompleteness and entered into the statistical software Epi-info version 7 and exported to SPSS version 20 software for descriptive and bi-variable analysis. To identify variables associated with the healthcare-seeking behavior. Logistic regression analysis was performed. Adjusted odds ratios with a 95% confidence interval were used to see the strength of association, and variables with P-values of < 0.05 were considered statistically significant.

RESULTS

The proportion of health care seeking behavior of care-givers for childhood illness was 69.5% (95% CI, 66.4, 72.4%). The education level of caregiver (AOR: 1.61, 95% CI: 1.01-2.60), knowledge of childhood illness (AOR: 2.02, 95% CI: 1.46-2.79), cough (AOR: 1.94, 95% CI: 1.39-2.71) and diarrhea (AOR: 2.09, 95% CI: 1.46-2.99) as main symptoms of illness and perceived severity of illness (AOR:3.12, 95% CI: 2.22-4.40) were significantly associated with healthcare-seeking behaviors of caregivers.

CONCLUSION

Low healthcare-seeking behavior was observed for childhood illnesses. Educational level, knowledge of childhood illness, cough, and diarrhea as primary symptoms of illness, and perceived severity of caregiver illness were significant associated with healthcare-seeking behavior. Therefore, interventions that strengthen the caregiver's awareness of childhood illness and danger signs need to be considered. Besides, addressing the identified associated variables to healthcare-seeking behavior is critically important to curb the problem.

Associations of maternal characteristics and dietary factors with anemia and iron-deficiency in pregnancy

OBJECTIVE

Anemia and iron deficiency during pregnancy influence maternal and fetal health, birth outcomes, and the risk of chronic disease in offspring. This study aimed to examine the association with sociodemographic, maternal factors, supplement use and dietary intakes, and anemia and iron deficiency in pregnancy.

METHODS

A cross-sectional study was conducted on 165 pregnant women aged between 19 and 45 years who were interviewed, and dietary intake was assessed by 24-hours dietary recall, supplement records and food frequency questionnaire. Learning Vector Quantization feature selection method which is one of the machine learning techniques was used to extract important variables from sociodemographic, maternal, and dietary factors.

RESULTS

The prevalence of anemia was 15.2% and prevalence of iron deficiency was 65.5%. Total intake of iron, phosphorus, vitamin B₁ and B₂ were importance factors for iron deficiency while age, number of births, use of folic acid supplement, dietary folate equivalent and total iron intake were importance factors for anemia.

CONCLUSIONS

Maternal and dietary characteristics were the most crucial risk factors for anemia while dietary factors were the most important risk factor for iron deficiency in pregnancy. The development of anemia and iron deficiency is associated with the coexistence of many nutrient deficiencies.

Contents of Metal(loid)s in a Traditional Ethiopian Flat Bread (Injera), Dietary Intake, and Health Risk Assessment in Addis Ababa, Ethiopia

The traditional Ethiopian flat bread, injera, is a regular component of daily diets in Ethiopia and Eritrea. This bread is also popular among urban refugees particularly Eritreans in Addis Ababa. The levels of metal(loid)s in 40 composite (120 sub-samples) injera samples, representing 4 types of market establishments in Addis Ababa, were determined using inductively coupled plasma-mass spectrometry (ICP-MS) and portable X-ray fluorescence (PXRF). For ICP-MS analysis, the accuracy of the method was evaluated by the analysis of a certified reference material and recovery experiments. It was found that the correlations between the mean levels of Al and Fe and between Al and Mn in injera were highly significant (p < 0.001). It was also found that 1.5 fresh injeras would cover 48-75% of recommended dietary allowance (RDA) for Mg, 17-21% of RDA for K, 19-23% of RDA for Ca, and 60-72% of RDA for P for an adult group aged between 19 and 50. Daily intakes of Al, Fe, and Mn were found to be above the provisional tolerable daily intake (PTDI)/maximum tolerable daily intake (MTDI) values. The mean target hazard quotient (THQ) values for Fe and Mn were greater than 1. The total THQ values varied from 6.52 to 8.53 among market establishments. Estimating carcinogenic risk due to exposure to As, Cr, and Pb indicated that perennial injera consumers might remain at cancer risk. This would further escalate if other staple food items and spices are considered. Hence, there is a need for home-based strategies to reduce extrinsic soil-Al-Fe-Mn in injera/tef batter.

Determinants of Anemia among Pregnant Women at Public Hospitals in West Shewa, Central Ethiopia: A Case-Control Study

Introduction. Anemia is highly dominant among pregnant women due to the need for iron for women themselves and their fetuses. Nearly half a billion globally and around one-third in Ethiopia of pregnant women were affected by anemia which has both health and economic impact. Therefore, this study aimed to identify the determinants of anemia among pregnant women attending antenatal care at public hospitals in the West Shewa zone, Oromia regional state, Central Ethiopia, 2019. Methods. An unmatched case-control study was conducted at public hospitals in the West Shewa zone, Ethiopia, from February to April 2019. A consecutive sampling was used to select study participants. Data were collected by a structured questionnaire, and the collected data were entered into Epi Info version 7 and SPSS version 23 for analyses. Descriptive statistics such as tables, graphs, and proportions were used to present the data. Binary and multiple logistic regression analyses were computed to identify the determinants of anemia. Adjusted odds ratio (AOR) with 95% confidence interval (CI) and $p$ value <0.05 were used to determine the presence of an association. Result. A total of 426 women (142 cases and 284 controls) participated in this study with a 95.3% response rate. Family size >5 (AOR = 2.95, 95% CI: 1.34–6.50), peptic ulcer diseases (PUD) (AOR = 2.85, 95% CI: 1.14–7.13), having the previous history of abortion (AOR = 2.84, 95% CI: 1.08–7.47), birth interval <2 years (AOR = 2.61, 95% CI: 1.20–5.70), antepartum hemorrhage (APH) (AOR = 6.05, 95% CI: 1.95–18.81), and not using latrine (AOR = 3.45, 95% CI: 1.30–9.24) were the identified determinants of anemia. Conclusions. Family size, PUD, abortion, birth interval, APH, and unable to use latrine were the determinants of anemia among pregnant women. Therefore, the intervention on anemia prevention should consider the promotion of family planning methods and counseling on latrine utilization.

Nutritional-Related Predictors of Anemia among Pregnant Women Attending Antenatal Care in Central Ethiopia: An Unmatched Case-Control Study

Background

Anemia is a major public health problem in both developed and developing countries especially among pregnant women. Nearly half of pregnant women in Ethiopia have anemia which has both health and economic impacts. Therefore, this study is aimed at identifying nutritional-related predictors of anemia among pregnant women attending antenatal care in Central Ethiopia, 2019.

Methods

An unmatched case-control study was conducted at public hospitals in Central Ethiopia from February to April 2019. The consecutive sampling technique was used to select study participants. Data were collected by a structured questionnaire, and the collected data were entered into Epi Info version 7 and SPSS version 23 for analysis. Binary and multiple logistic regression analyses were computed to identify predictors of anemia. Adjusted odds ratio (AOR) with 95% confidence interval (CI) and p value < 0.05 was used to determine the presence of an association.

Result

A total of 426 pregnant women (142 cases and 284 controls) had participated in this study. Taking tea/coffee immediately after food (AOR = 2.35, 95% CI: 1.39-3.99), mid-upper arm circumference (MUAC) of mothers of <23 centimeters (AOR = 3.83, 95% CI: 2.26-6.49), the presence of forbidden food during pregnancy (AOR = 2.21, 95% CI: 1.24-3.88), not taking additional food (AOR = 1.99, 95% CI: 1.17-3.40), unable to take fruit (AOR = 4.05, 95% CI: 1.3-15.47), loss of appetite (AOR = 2.28, 95% CI: 1.28-4.09), low dietary diversity score (DDS) (AOR = 3.29, 95% CI: 1.83-5.90), and medium DDS (AOR = 2.88, 95% CI: 1.46-5.70) were found to be determinants of anemia.

Conclusions

Taking tea or coffee immediately after food, MUAC of mothers, the presence of forbidden food, not taking additional food, frequency of taking fruit, and dietary diversity were predictors of anemia among pregnant women. Therefore, interventions targeted at prevention of anemia among pregnant mothers should emphatically consider those identified determinants. This finding also highlights the need for strong nutritional counseling to prevent anemia among pregnant mothers during antenatal care follow-ups along with other interventions.

Prevalence of anemia and iron deficiency anemia in Chinese pregnant women (IRON WOMEN): a national cross-sectional survey

Background

The current evidence about anemia and iron deficiency anemia (IDA) during pregnancy remains elusive in China. The purpose of this study is to investigate the prevalence of anemia and IDA and their risk factors in Chinese pregnant women.

Methods

A nationwide cross-sectional survey of pregnant women was conducted during their antenatal visits. Using a multi-stage sampling method, 24 hospitals from 16 provinces across China were selected. Structured questionnaires were administered to collect information from participants and to extract clinical data from electronic medical records. Mixed-effects logistic regression models were performed to determine the risk factors associated with anemia and IDA.

Results

In total, 12,403 pregnant women were enrolled, including 1018 (8.2%) at the first trimester, 3487 (28.1%) at the second, and 7898 (63.7%) at the third. Overall, 19.8% of women were diagnosed with anemia and 13.9% were diagnosed with IDA. The prevalence of anemia and IDA varied among regions and increased by gestational month, peaking at the eighth gestational month (24.0% for anemia and 17.8% for IDA). Pregnant women at advanced stage of gestation, non-local residents, multiple gestations, multiparity, pre-pregnancy underweight, and those experiencing severe nausea or vomiting during pregnancy, were associated with higher risks of anemia and IDA.

Conclusions

The prevalence of anemia and IDA during pregnancy are similar to those from developed countries and vary across regions in China.

Integrating Calcium Into Antenatal Iron-Folic Acid Supplementation in Ethiopia: Women's Experiences, Perceptions of Acceptability, and Strategies to Support Calcium Supplement Adherence

Recommendations for antenatal calcium supplementation to prevent preeclampsia could substantially reduce maternal mortality, but adherence to multiple daily doses may constrain effectiveness. World Health Organization guidelines recommend 3 daily calcium supplements (1.5-2 g/d), taken separately from 1 iron-folic acid (IFA) supplement; however, limited data suggest lower calcium doses may also be effective. We conducted mixed-methods household trials to identify strategies for supporting adherence and integrating calcium into antenatal IFA supplementation programming in Ethiopia. Participants were randomly assigned to 3 regimens varying in dose and timing and were later given a choice of regimens. Semistructured interviews conducted over 6 weeks explored acceptability, barriers, and facilitators and offered opportunities to choose calcium pill type. Interviews were transcribed, translated, and analyzed thematically. Calcium adherence was measured using medication event monitoring. All participants (N=48) agreed to try supplementation. Adherence barriers included forgetting to take pills when busy or travelling and perceived side effects. Midday doses were the most challenging because of farming, market, and social events; women avoided taking supplements in public due to fear of being perceived as HIV positive. Social support from families, visual reminders, and anticipated benefits motivated adherence. More participants (75%) selected chewable versus conventional supplements due to organoleptic properties, but this preference declined over time. Adherence rates did not substantially differ across regimens with 2 (81.1%), 3 (83.4%), or 4 (77.1%) pill-taking events. Women indicated that the 2-event regimen was more acceptable than 3- and 4-event regimens, but this acceptability was not associated with higher adherence. Consequently, mean daily calcium consumption (811.3 mg) was lower than for 3-event (1,251.1 mg) and 4-event (1,156.4 mg) regimens. Integrating calcium into antenatal IFA supplementation is acceptable to Ethiopian women, with a 3-event regimen yielding the highest consumption rates. Despite women experiencing challenges with midday dosing and stigma, using simple home-based strategies and being counseled on the purpose of supplementation were more effective than reducing dosage for mitigating barriers and improving adherence.

Association between Helicobacter pylori Infection and Occurrence of Anemia among Pregnant Women Attending Antenatal Care in Kulito Health Center, Halaba Zone, South Ethiopia, 2018

Background

Anemia in pregnancy is defined as a hemoglobin (Hb) concentration of less than 11 grams (gm)/deciliter (dl) in venous blood. Globally, it affects 1.62 billion people. In developing countries, anemia is a major cause of maternal and child morbidity and mortality. Globally, anemia contributes to 20% of all maternal deaths. Nearly 50% of the world's population is estimated to be infected with Helicobacter pylori (HP). High prevalence of HP among pregnant women was also reported in developing countries than developed ones. The association between HP infection and occurrence of anemia is not well known in Ethiopia. Therefore, the aim of this study was to determine the association between anemia and Helicobacter pylori infection among pregnant women attending antenatal care follow-up in Kulito Health Center, Halaba Zone, South Ethiopia.

Methods

Institution-based cross-sectional study was employed. Systematic random sampling procedure was employed to select 236 pregnant women who attended antenatal care at Kulito Health Center. An interviewer-administered questionnaire supplemented by laboratory tests was used to obtain the data. The collected data were analyzed by using SPSS version 20.0.

Results

The prevalence of anemia among antenatal care attendant pregnant women of Kulito Health Center was 27.5% with 36 (15.2%) of mild, 29 (12.3%) of moderate, and no severe cases of anemia. The overall prevalence of HP infection among study participants was found to be 129 (54.7%) (95% CI: 47.9–61.4). Factors significantly associated with anemia were presence of HP infection (AOR = 3.064, 95% CI: 1.336 7.027), low interpregnancy gap (AOR = 2.863, 95% CI: 1.245–6.582), being on the third trimester (AOR = 6.457; 95% CI: 1.276–32.729), and mid-upper arm circumference (MUAC) level <21 cm (AOR = 2.595, 95% CI: 1.044–6.450).

Conclusion

This study revealed that anemia and HP infection were highly prevalent among pregnant women attending the antenatal follow-up clinic in Kulito Health Center. HP infection, low interpregnancy gap, being on the third trimester, and MUAC less than 21 cm were the independent factors associated with anemia. Recommendation. Pregnant women should be aware that anemia is a problem that can be prevented by early prevention and treatment of HP infection and undernutrition, using family planning to widen the interpregnancy gap. Further experimental studies are warranted to determine the cause and effect of the association between anemia and HP infection.

Determinants of anemia among pregnant women attending antenatal care in Horo Guduru Wollega Zone, West Ethiopia: Unmatched case-control study

BACKGROUND

Anemia is a common clinical problem contributing to increased maternal and fetal morbidity and mortality during pregnancy. Anemia can be caused by different factors apart from known diseases. The main aim of this study was to identify determinants of anemia among pregnant women attending antenatal care at the public health facilities of Horo Guduru Wollega Zone, West Ethiopia, 2017.

METHODS

Health facility-based unmatched case-control study was conducted among 191 anemic and 382 non-anemic pregnant women from September 7, 2017, to October 25, 2017, in Horo Guduru Wollega Zone, West Ethiopia. Data were collected using pre-tested questionnaires from nine health facilities. Hemoglobin level determination, hemo-parasite diagnosis, venereal disease research laboratory (VDRL) test, and stool examination were done in the laboratories of the respective health centers. Cleaned and coded data were entered and analyzed using SPSS version 20. Frequency, proportion, mean and standard deviation were computed to summarize the data and presented by tables and bar graphs. Multivariate binary logistic regression analysis was used to determine the association of predictors and response variables at P ≤ 0.05. Adjusted odds ratio with 95% CI was used to show the strength of association between predictors and outcome variables.

RESULTS

A total of 573 pregnant women were enrolled in this study. Monthly income < 500 Ethiopian birr (AOR = 9.16, 95% CI: 4.23, 19.82), heavy menstrual bleeding (AOR = 2.38, 95%CI: 1.38, 4.09), taking iron supplement irregularly (AOR = 2.87, 95%CI:1.41, 5.84), Mid-upper Arm Circumference (MUAC) < 23 cm (AOR = 3.42, 95%CI: 2.07, 5.63), low dietary diversity score (AOR = 12.30, 95%CI: 4.64, 32.72), medium dietary diversity score (AOR = 3.40, 95%CI:1.48, 7.84) and intestinal helminthic infections (AOR = 6.31, 95%CI: 3.44, 11.58) were significantly associated with anemia during pregnancy.

CONCLUSION

Average monthly income < 500 Ethiopian birr, heavy menstrual bleeding, low and medium dietary diversity score, taking of iron supplements irregularly, MUAC < 23 cm and intestinal helminthic infections were identified as independent determinants of anemia during pregnancy. Therefore, improving dietary diversity intake, routine deworming and empowering women on taking iron regularly are vital to prevent anemia during pregnancy.

Maternal dietary diversity and micronutrient adequacy during pregnancy and related factors in East Gojjam Zone, Northwest Ethiopia, 2016

Background

Monotonous and less diversified diets are associated with micronutrient deficiency. Evidence on maternal dietary intakes during pregnancy is essential to achieve the 2025 global nutrition target and reduce maternal and child mortalities. This study assessed pregnant women’s dietary diversity and identified factors associated with inadequate dietary diversity in East Gojjam Zone.

Methods

We conducted a community-based cross-sectional study between April and June 2016. Eight hundred thirty-four pregnant women were randomly sampled. The Women Dietary Diversity Score tool developed by the Food and Agricultural Organization (FAO) and Food and Nutrition Technical Assistance (FANTA) was used. Data were entered into EpiData with double entry verification, and analysis was done using IBM SPSS version 20. Level of significance was set to P < 0.05 with 95% confidence interval (CI) to identify the independent factors associated with inadequate dietary diversity.

Results

The mean (±SD) dietary diversity score was 3.68 (±2.10). Inadequate dietary diversity was prevalent in 55% [95% CI (52.3–59.3%)] of pregnant women, or indirectly micronutrient was inadequate in more than half of the pregnant women. Commonly consumed dietary groups were legumes, nuts, and seeds (85.5%) followed by starchy staples (64.7%). Inadequate dietary diversity was higher among non-educated [Adjusted Odds Ratio (AOR) = 7.30, 95% CI (2.35–22.68)] compared to college and above completed women. Wealth index had significant association with dietary diversity, in which women in the poorest [AOR = 8.83, 95% CI, (1.60–48.61)], poorer [AOR = 6.34, 95% CI (1.16–34.65)], poor [AOR = 8.46, 95% CI (1.56–45.70)], and richer [AOR = 6.57, 95% CI (2.16–20.01)] had higher odds of inadequate dietary diversity. Those who had not received dietary counseling had three folds [AOR = 3.31, 95% CI (1.49–7.35)] of inadequate dietary diversity compared to their counterparts. Less likelihood of inadequate dietary diversity was among women with an increased meal frequency [AOR = 0.53, 95% CI (0.38–0.74)].

Conclusion

Consumption of less diversified food during pregnancy is common in the study area. Adequacy of micronutrients is insufficient for more than half of the studied pregnant women. We conclude that being non-educated affects pregnant women to depend on less diversified diet. Providing dietary counseling during pregnancy can improve nutritional practice for pregnant women.

Prevalence, types and determinants of anemia among pregnant women in Sudan: a systematic review and meta-analysis

Background

Anemia during pregnancy is a public health problem especially in developing countries and it is associated with maternal and perinatal adverse outcomes. There is no meta-analysis on anemia during pregnancy in Sudan. The current systemic review and meta-analysis was conducted to assess the prevalence, types and determinant of anemia during pregnancy in Sudan.

Methods

Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed. The databases (PubMed, Cochrane Library, Google Scholar, CINAHL, and African Journals Online) were searched using; anemia, pregnancy related anemia and Sudan. Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI) and Modified Newcastle – Ottawa quality assessment scale were used for critical appraisal of studies. The pooled Meta logistic regression was computed using OpenMeta Analyst software.

Results

Sixteen cross-sectional studies included a total of 15, 688 pregnant women were analyzed. The pooled prevalence of anemia among pregnant women in Sudan was 53.0% (95%, CI = 45.9–60.1). The meta-analysis showed no statistical significant between the age (mean difference = 0.143, 95 CI = − 0.033 − 0.319, P = 0.112), parity (mean difference = 0.021, 95% CI = − 0.035 − 0.077, P = 0.465) between the anemic and no anemic women. Malaria was investigated in six studies. Pregnant women who had malaria infection during pregnancy were 1.94 times more likely to develop anemia than women who had no malaria infection (OR = 1.94, 95% CI =1.33–2.82). Six (37.5%) studies investigated type of anemia. The pooled prevalence of iron deficiency anemia (IDA) among pregnant women in Sudan was 13.6% (95% CI = 8.9–18.2).

Conclusion

There is a high prevalence of anemia among pregnant in the different region of Sudan. While age and parity have no association with anemia, malaria infection was associated with anemia. Interventions to promote the strengthening of antenatal care, and access and adherence to nutrition, and malaria preventive measures are needed to reduce the high level of anemia among pregnant women in Sudan.
