Determinants of adverse birth outcome in Sub-Saharan Africa: analysis of recent demographic and health surveys

Preterm birth, low birth weight, and their co-occurrence among women with preexisting chronic diseases prior to conception: a cross-sectional analysis of postpartum women in a low-resource setting in Ghana

BACKGROUND

The incidence of chronic diseases, which are significant contributors to maternal deaths and adverse new-born outcomes, is increasing among women of reproductive age in northern Ghana. This emerging health issue raises serious concerns about the potential exacerbation of adverse birth outcomes in this setting, given that it is one of the regions in the country with a high incidence of such outcomes. We investigated the risks of preterm birth (PTB), low birth weight (LBW), and concurrent PTB and LBW among women with preexisting chronic conditions prior to conception in the Tamale Metropolis of northern Ghana.

METHODS

A facility-based cross-sectional study was conducted among 420 postpartum women randomly selected from five public health facilities. Information was collected electronically on participants' self-reported experience of chronic conditions, namely, hypertension, diabetes, asthma, heart disease, and sickle cell disease, prior to their most recent pregnancy. Information on gestational age at delivery and birth weight was also collected. Regression modeling was used to quantify the risk of adverse newborn outcomes among women who reported preexisting chronic conditions prior to pregnancy.

RESULTS

Chronic diseases affected 31.2% of our sample. Of these, 28.6% had a single chronic condition, while 2.6% had comorbid chronic conditions. The prevalence of PTB was 24.0% (95% CI: 20.2, 28.4), 27.6% (95% CI: 23.5, 32.1) of the newborns were born LBW, and 17.4% (95% CI: 14.0, 21.3) of the pregnancies resulted in both PTB and LBW. Compared with those without chronic conditions, women with chronic conditions prior to conception had a greater risk of PTB (aOR = 6.78, 95% CI: 3.36, 13.68), LBW (aOR = 5.75, 95% CI: 2.96, 11.18), and the co-occurrence of PTB and LBW (aOR = 7.55, 95% CI: 3.32, 17.18).

CONCLUSIONS

We observed significant rates of PTB, LBW, and the co-occurrence of PTB and LBW among women who were already aware that they had preexisting chronic conditions prior to conception. Our findings highlight a potential gap in the quality of prenatal care provided to these women before delivery. Preconception care may offer an opportunity to address preexisting chronic conditions in women before pregnancy and potentially improve maternal and newborn health outcomes.

Predicting adverse birth outcome among childbearing women in Sub-Saharan Africa: employing innovative machine learning techniques

BACKGROUND

Adverse birth outcomes, including preterm birth, low birth weight, and stillbirth, remain a major global health challenge, particularly in developing regions. Understanding the possible risk factors is crucial for designing effective interventions for birth outcomes. Accordingly, this study aimed to develop a predictive model for adverse birth outcomes among childbearing women in Sub-Saharan Africa using advanced machine learning techniques. Additionally, this study aimed to employ a novel data science interpretability techniques to identify the key risk factors and quantify the impact of each feature on the model prediction.

METHODS

The study population involved women of childbearing age from 26 Sub-Saharan African countries who had given birth within five years before the data collection, totaling 139,659 participants. Our data source was a recent Demographic Health Survey (DHS). We utilized various data balancing techniques. Ten advanced machine learning algorithms were employed, with the dataset split into 80% training and 20% testing sets. Model evaluation was conducted using various performance metrics, along with hyperparameter optimization. Association rule mining and SHAP analysis were employed to enhance model interpretability.

RESULTS

Based on our findings, about 28.59% (95% CI: 28.36, 28.83) of childbearing women in Sub-Saharan Africa experienced adverse birth outcomes. After repeated experimentation and evaluation, the random forest model emerged as the top-performing machine learning algorithm, with an AUC of 0.95 and an accuracy of 88.0%. The key risk factors identified were home deliveries, lack of prenatal iron supplementation, fewer than four antenatal care (ANC) visits, short and long delivery intervals, unwanted pregnancy, primiparous mothers, and geographic location in the West African region.

CONCLUSION

The region continues to face persistent adverse birth outcomes, emphasizing the urgent need for increased attention and action. Encouragingly, advanced machine learning methods, particularly the random forest algorithm, have uncovered crucial insights that can guide targeted actions. Specifically, the analysis identifies risky groups, including first-time mothers, women with short or long birth intervals, and those with unwanted pregnancies. To address the needs of these high-risk women, the researchers recommend immediately providing iron supplements, scheduling comprehensive prenatal care, and strongly encouraging facility-based deliveries or skilled birth attendance.

Adverse birth outcome among women who gave birth at the University of Gondar comprehensive specialized hospital, Northwest Ethiopia

BACKGROUND

In Ethiopia, various maternal and child health interventions, including comprehensive and basic obstetric cares were conducted to curb high neonatal and infant morbidity and mortality. As such, adverse birth outcome has been a public health concern in the country. Thus, this study aimed to assess the burden and associated factors with adverse birth outcomes among women who gave birth at the University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia.

METHODS

A health facility-based cross-sectional study was employed from 30 March to 01 May 2021 at the University of Gondar Comprehensive Specialized Hospital. A total of 455 women were interviewed using a structured questionnaire. A binary logistic regression model was fitted Adjusted Odds Ratio (AOR) with 95%CI and p-value < 0.05 were used to declare factors significantly associated with adverse birth outcomes.

RESULTS

In this study, 28% of women had adverse birth outcomes (8.4% stillbirths, 22.9% preterm births, and 10.11% low birth weights). Women aged 20-34) (AOR: 0.32, 95%CI: 0.14, 0.76), rural dwellers (AOR: 2.7, 95%CI: 1.06, 6.32), lack of ANC visits (AOR: 4.10, 95%CI: 1.55, 10.85), APH (AOR: 3.0, 95%CI: 1.27, 7.10) and fever (AOR: 7.80, 95%CI: 3.57, 17.02) were associated to stillbirths. Multiple pregnancy (AOR:7.30, 95%CI:1.75, 20.47), rural dwellers (AOR:4.60, 95%CI:1.36, 15.52), preterm births (AOR: 8.60, 95% CI: 3.88, 19.23), previous perinatal death (AOR:2.90, 95%CI:1.35, 6.24), fever (AOR:2.7,95%CI:1.17 ,6.23) and premature rupture of membrane (AOR:2.60, 95% CI:1.02, 6.57) were affecting low birth weights. In addition, previous antepartum hemorrhage (AOR: 2.40, 95%CI: 1.37, 4.10) and fever (AOR: 3.8, 95%CI: 2.13, 6.89) were also factors contributing to preterm births.

CONCLUSION

Adverse birth outcomes continue to pose a significant public health concern. Such high rates of adverse birth outcomes, such as preterm birth, low birth weight, and birth defects, can have serious and long-lasting effects on the health and well-being of both infants and their families, and the community at large. As such, public health efforts are crucial in addressing and mitigating the risk factors associated with adverse birth outcomes. This may involve implementing interventions and policies to improve maternal health, access to prenatal care and nutritional support, and reducing exposure to environmental risks.

Risk factors of adverse birth outcomes among a cohort of pregnant women in Coastal Kenya, 2017-2019

INTRODUCTION

Adverse birth outcomes particularly preterm births and congenital anomalies, are the leading causes of infant mortality globally, and the burden is highest in developing countries. We set out to determine the frequency of adverse birth outcomes and the risk factors associated with such outcomes in a cohort of pregnant women in Kenya.

METHODS

From October 2017 to July 2019, pregnant women < 28 weeks gestation were enrolled and followed up until delivery in three hospitals in coastal Kenya. Newborns were examined at delivery. Among women with birth outcome data, we assessed the frequency of congenital anomalies defined as gastroschisis, umbilical hernia, limb abnormalities and Trisomy 21, and adverse birth outcomes, defined as either stillbirth, miscarriage, preterm birth, small for gestational age, or microcephaly. We used log-binomial regression to identify maternal characteristics associated with the presence of at least one adverse outcome.

RESULTS

Among the 2312 women enrolled, 1916 (82.9%) had birth outcome data. Overall, 402/1916 (20.9%; 95% confidence interval (CI): 19.1-22.8) pregnancies had adverse birth outcomes. Specifically, 66/1916 (3.4%; 95% CI: 2.7-4.4) were stillbirths, 34/1916 (1.8%; 95% CI: 1.2-2.4) were miscarriages and 23/1816 (1.2%; 95% CI: 0.8-1.9) had congenital anomalies. Among the participants with anthropometric measurements data, 142/1200 (11.8%; 95% CI: 10.1 - 13.8) were small for gestational age and among the participants with ultrasound records, 143/1711 (8.4%; 95% CI: 7.1-9.8) were preterm. Febrile illnesses in current pregnancy (adjusted risk ratio (aRR): 1.7; 95% CI: 1.1-2.8), a history of poor birth outcomes in prior pregnancy (aRR: 1.8; 95% CI: 1.3-2.4) and high blood pressure in pregnancy (aRR: 3.9, 95% CI: (1.7-9.2) were independently associated with adverse birth outcomes in a model that included age, education, human immunodeficiency virus status and high blood pressure at enrolment.

CONCLUSION

We found similar rates of overall adverse birth outcomes, congenital anomalies, and small for gestational age but higher rates of stillbirths and lower rates of prematurity compared to the rates that have been reported in the sub-Saharan Africa region. However, the rates of adverse birth outcomes in this study were comparable to other studies conducted in Kenya. Febrile illnesses during the current pregnancy, previous history of poor birth outcomes and high blood pressure in pregnancy are predictive of an increased risk of adverse birth outcomes.

Gestational diabetes mellitus in Cameroon: prevalence, risk factors and screening strategies

Background

The burden of gestational diabetes (GDM) and the optimal screening strategies in African populations are yet to be determined. We assessed the prevalence of GDM and the performance of various screening tests in a Cameroonian population.

Methods

We carried out a cross-sectional study involving the screening of 983 women at 24-28 weeks of pregnancy for GDM using serial tests, including fasting plasma (FPG), random blood glucose (RBG), a 1-hour 50g glucose challenge test (GCT), and standard 2-hour oral glucose tolerance test (OGTT). GDM was defined using the World Health Organization (WHO 1999), International Association of Diabetes and Pregnancy Special Group (IADPSG 2010), and National Institute for Health Care Excellence (NICE 2015) criteria. GDM correlates were assessed using logistic regressions, and c-statistics were used to assess the performance of screening strategies.

Findings

GDM prevalence was 5·9%, 17·7%, and 11·0% using WHO, IADPSG, and NICE criteria, respectively. Previous stillbirth [odds ratio: 3·14, 95%CI: 1·27-7·76)] was the main correlate of GDM. The optimal cut-points to diagnose WHO-defined GDM were 5·9 mmol/L for RPG (c-statistic 0·62) and 7·1 mmol/L for 1-hour 50g GCT (c-statistic 0·76). The same cut-off value for RPG was applicable for IADPSG-diagnosed GDM while the threshold was 6·5 mmol/L (c-statistic 0·61) for NICE-diagnosed GDM. The optimal cut-off of 1-hour 50g GCT was similar for IADPSG and NICE-diagnosed GDM. WHO-defined GDM was always confirmed by another diagnosis strategy while IADPSG and GCT independently identified at least 66·9 and 41·0% of the cases.

Interpretation

GDM is common among Cameroonian women. Effective detection of GDM in under-resourced settings may require simpler algorithms including the initial use of FPG, which could substantially increase screening yield.

Independent and joint contributions of inadequate antenatal care timing, contacts and content to adverse pregnancy outcomes

BACKGROUND

Poor quality and inadequate of antenatal care (ANC) visits during pregnancy may increase the risk of preventable adverse pregnancy outcomes. We tested the hypothesis that the adequacy of ANC utilization combined with quality of ANC services will reduce the risk of low birth weight (LBW) and preterm delivery (P T D) in the Tamale metropolis of Ghana.

MATERIALS AND METHODS

A facility-based analytical cross-sectional study was conducted on a sample of 553 postpartum women who had delivered within the last 12 months prior to the study. The overall utilization of ANC services was measured in terms of ANC timing, contacts, and content (TCC) of essential ANC services. The sample was drawn using systematic random sampling procedure. Primary data was collected from mothers by administering a structuredquestionnaire while the secondary data was extracted from individual records.

RESULTS

After controlling for confounders, women who had adhered to all WHO recommendations in terms of ANC timing, frequency and content were 71 % protected from PTD, AOR = 0.29 (95 % CI: 0.15, 0.59) and 56 % protection from LBW AOR = 0.44 (95 % CI: 0.23, 0.83).

CONCLUSION

Individually and jointly, inadequate ANC contacts and content associatedsignificantly with preterm delivery than LBW.Key messagesLimited evidence exists on the joint effect of ANC services timing, contacts and content on adverse pregnancy outcomes.Total adherence to recommended ANC initiation, attendance and receipt of essential services had greater protection against PTD and LBW, compared to any single element/component of ANCWomen who had adequate overall ANC services utilization in terms of timing, contacts and content were 71 % protected from PTD, AOR = 0.29 (95 % CI: 0.15, 0.59) and 56 % protection from LBW AOR = 0.44 (95 % CI: 0.23, 0.83).

Disparities in health and nutrition between semi-urban and rural mothers and birth outcomes of their newborns in Bukavu, DR Congo: a baseline assessment

AIM

This research aimed to evaluate health and nutritional practices of mothers during pregnancy and birth outcomes of their newborns in Bukavu, Democratic Republic of the Congo (DRC), comparing semi-urban and rural areas.

BACKGROUND

Health and nutrition during pregnancy are crucial for adequate development of the fetus. Health care plays an important role but is often poor in rural areas of developing countries.

METHODS

A baseline survey of a nutritional follow-up study was conducted in two semi-urban and one rural hospital in the vicinity of Bukavu, DRC. In total, 471 mother-child pairs were recruited after delivery. Data collection included socio-demographic parameters, nutrition and health measures during pregnancy, and anthropometric parameters. Semi-urban and rural study locations were compared and predictors of birth weight evaluated.

FINDINGS

Semi-urban and rural mothers differed significantly in nutrition and health practices during pregnancy, as well as birth outcomes. In the rural area, there was a higher rate of newborns with low birth weight (10.7%) and lower rates of antimalarial medication (80.8%), deworming (24.6%), consumption of nutritional supplements (81.5%), and being informed about nutrition by medical staff (32.8%) during pregnancy as well as practicing family planning (3.1%) than in the semi-urban areas (2.7%, 88.6%, 88.3%; 89.3%, 46.5%, and 17.1%, respectively). Birth weight was positively predicted by increasing maternal MUAC, age, and gestational age and negatively by rural location, being primipara, being a farmer, and female newborn sex.

CONCLUSION

The findings highlight the importance of strengthening antenatal care activities especially in rural areas in order to ameliorate both maternal and infantile health and ensure appropriate development.

Antenatal depression and adverse birth outcomes among pregnant women living with HIV in Dar es Salaam, Tanzania

BACKGROUND

Women who experience antenatal depression may be at increased risk of adverse birth outcomes. Few studies have examined this association among women living with HIV (WHIV).

METHODS

We conducted a prospective cohort study of 2298 pregnant WHIV on antiretroviral therapy (ART) in Dar es Salaam, Tanzania, who were participants in a randomized trial of vitamin D3 supplementation. Depressive symptoms were assessed at 12-27 weeks gestation using the Hopkins Symptoms Checklist (HSCL-25). Generalized estimating equations to account for twins were used to assess the relative risks of adverse birth outcomes.

RESULTS

Approximately 67 % of the women in our study population reported symptoms consistent with depression. We observed a 4.0 % prevalence of stillbirth and a 25.1 % prevalence of preterm birth. We found that low social support, higher education, and more recent initiation of ART were associated with a greater risk of antenatal depression. There was no association of antenatal depression with risk of fetal loss, stillbirth, low birth weight, birth weight, preterm birth, gestational age at delivery, or small-for-gestational age.

LIMITATIONS

Depression was self-reported and only collected at one timepoint in pregnancy. Our findings may not be generalizable to all WHIV.

CONCLUSIONS

Our findings illustrate the high risk of both depression and adverse birth outcomes among WHIV and underscore the need for interventions to improve their mental health and the health of their infants; however, the relationship between depression and birth outcomes remains unclear. Further research on this topic is merited, particularly examining the chronicity and timing of depression in pregnancy.

Determinants of Adverse Birth Outcomes in Public Hospitals of the Somali Region, Eastern Ethiopia: A Multicenter Unmatched Case-Control Study

Background

Pregnancy outcomes that differ from normal live births are known as adverse pregnancy outcomes. Adverse pregnancy outcomes also have significant effects on the infant's family and society. There is limited data on adverse outcomes in eastern Ethiopia, particularly in the Somali region.

Objectives

This study aimed to assess the determinants of adverse birth outcomes in the Somali Region Hospitals.

Design

A hospital-based unmatched case-control study was conducted to conduct this study.

Methods

A hospital-based unmatched case-control study was conducted between June and July 2021 in pregnant women who attended public hospitals in the Somali region. A total of 327 (109 cases and 218 controls) participants were included in this study. Women who gave birth with at least 1 adverse birth outcome were considered cases, and those who gave birth with normal birth outcomes were considered controls. Cases were recruited consecutively, and controls were selected using systematic sampling methods. Data was gathered using interviews, record reviews, using the pretested standard tools. The data were entered into EpiData version 3.1 and analyzed with SPSS version 22. Multivariable regression analysis with an adjusted odds ratio and a 95% confidence interval was used to identify the factors associated with adverse birth outcomes. Finally, P-values less than .05 were used to identify significantly associated predictors.

Results

In the current study, rural residency [AOR = 2.80; 95%CI:(1.61-4.87)] lack of ANC follow-up [AOR = 3.27; 95%CI: (1.77-6.02)], pregnancy-induced hypertension [AOR = 3.28; 95%CI: (1.74-6.17)] being anemic mothers [AOR = 3.51; 95%CI: (2.02-6.07)] and khat chewing [AOR = 4.54; 95%CI: (2.12-9.70)] were identified as determinants of adverse birth outcome.

Conclusions

In the current study, rural residency, lack of ANC, being anemic in indexed pregnancies, pregnancy-induced hypertension, and khat chewing were determinants of adverse birth outcomes. Therefore, efforts should be made to enhance ANC follow-up, iron and folic acid supplementation, early treatments of pregnancy-induced hypertension, and information on the risk of chewing khat.

Risks of adverse perinatal outcomes in relation to maternal depressive symptoms: A prospective cohort study in Kenya

BACKGROUND

Evidence gaps remain regarding the influence of prenatal psychosocial factors on adverse pregnancy outcomes.

OBJECTIVE

The objective of this study is to evaluate relationships between psychosocial factors and adverse perinatal outcomes among Kenyan women.

METHODS

We analysed data from a prospective cohort study enrolling HIV-negative women in pregnancy (NCT03070600) in 20 antenatal clinics in Western Kenya. Study nurses assessed depressive symptoms using the Center for Epidemiologic Studies Depression Scale (CESD-10), social support using the Medical Outcomes Survey scale (MOS-SSS), intimate partner violence (IPV) with the Hurt, Insult, Threaten, Scream scale (HITS), and pregnancy outcomes at 6 weeks postpartum. Cox proportional hazards models were used to evaluate relationships between depressive symptoms (moderate-to-severe [MSD, CESD-10 ≥10] and mild-to-severe [Mild-SD, CESD-10 ≥5]), low social support (MOS-SSS <72), and IPV (HITS ≥10) with adverse perinatal outcomes of pregnancy loss, stillbirth, preterm birth (PTB), small for gestational age, and neonatal mortality. We also estimated the population attributable risk.

RESULTS

Among 4153 women, 23.9% (n = 994) had MSD, 54.7% (n = 2273) mild-SD, 37.3% (n = 1550) low social support, and 7.8% (n = 323) experienced IPV. Pregnancy loss was 5-fold higher among women with MSD (adjusted hazard ratio [HR] 5.04, 95% confidence interval [CI] 2.44, 10.42); 37.4% of losses were attributable to MSD. Mild-SD was associated with PTB (HR 1.39, 95% CI 1.03, 1.87). Stillbirth risk more than doubled among women reporting low social support (HR 2.37, 95% CI 1.14, 4.94).

CONCLUSIONS

Adverse perinatal outcomes were common and associated with prenatal depressive symptoms and low social support in this large cohort of Kenyan mother-infant pairs.

Compliance with the World Health Organization's 2016 prenatal care contact recommendation reduces the incidence rate of adverse birth outcomes among pregnant women in northern Ghana

BACKGROUND

Children born with adverse birth outcomes (ABOs) have a greater risk of mortality, stunting, and poor cognitive development. In 2016, the World Health Organization (WHO) recommended at least eight antenatal care (ANC) contacts before delivery for a healthy mother and baby. We examined the association between compliance with this recommendation and the risk of ABOs, such as low birthweight (LBW) and preterm birth (PTB), in the Tamale Metropolitan Area of the northern region of Ghana.

METHODS

We conducted a cross-sectional study in the Tamale Metropolis of the northern region of Ghana. We analysed a systematic random sample of 402 postnatal women aged 15-49 drawn from five public health facilities. We gathered information electronically on their birth outcomes, specifically their birthweight and gestation at delivery, using a structured questionnaire. Information on women's background characteristics, including the number of ANC contacts made before delivery, was also collected. The association between the number of ANC contacts and ABOs was investigated using regression models.

RESULTS

We found that 37.6% (95% CI: 32.9, 42.4) of our sample had at least eight ANC contacts before delivery. We estimated that 18.9% of babies were born prematurely and 9.0% were born LBW. ABOs were found in 22.9% (95% CI: 19.0, 27.3) of babies. A minimum of eight ANC contacts before delivery reduced the risk of ABOs (adjusted IRR = 0.43; 95% CI: 0.25, 0.73), PTB (AOR = 0.28; 95% CI: 0.14, 0.58), and LBW (AOR = 0.36; 95% CI: 0.14, 0.91).

CONCLUSION

In the current study's setting, about a quarter of newborns have ABOs, jeopardising their survival, health, and development. Compliance with at least eight ANC contacts prior to birth was associated with a reduced incidence rate ratio of ABOs. However, less than four out of every ten pregnant women make at least eight ANC contacts before delivery. Efforts are needed to increase coverage of eight contacts among pregnant women before delivery to reduce the risk of ABOs in the study setting.

The association between adverse pregnancy outcomes and non-viral genital pathogens among women living in sub-Saharan Africa: a systematic review

Adverse pregnancy outcomes are the main causes of maternal and neonatal morbidity and mortality, including long-term physical and psychological sequelae. These events are common in low- and middle-income countries, particularly in Sub Saharan Africa, despite national efforts. Maternal infections can cause complications at any stage of pregnancy and contribute to adverse outcomes. Among infections, those of the genital tract are a major public health concern worldwide, due to limited availability of prevention, diagnosis and treatment approaches. This applies even to treatable infections and holds true especially in Sub-Saharan Africa. As late as 2017, the region accounted for 40% of all reported treatable non-viral genital pathogens worldwide, many of which have been independently associated with various adverse pregnancy outcomes, and that include Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, Treponema pallidum. Two databases (PubMed and Embase) were examined to identify eligible studies published up to October 2022. This study reviewed findings on the association between infections by treatable non-viral genital pathogens during pregnancy and adverse pregnancy outcomes among women living in Sub-Saharan Africa. Articles' title and abstract were screened at first using keywords as "sexually transmitted infections", "non-viral", "adverse pregnancy outcome", "Africa", "sub-Saharan Africa", "pregnant women", "pregnancy", and "pregnancy outcome". Subsequently, according to the eligibility criteria, potential articles were read in full. Results showed that higher risk of preterm birth is associated with Treponema pallidum, Chlamydia trachomatis and Candida albicans infections. Additionally, rates of stillbirth, neonatal death, low birth weight and intrauterine growth restriction are also associated with Treponema pallidum infection. A better insight on the burden of non-viral genital pathogens and their effect on pregnancy is needed to inform antenatal care guidelines and screening programs, to guide the development of innovative diagnostic tools and other strategies to minimize transmission, and to prevent short- and long-term complications for mothers and children.

Maternal exposure to multiple mycotoxins and adverse pregnancy outcomes: a prospective cohort study in rural Bangladesh

There is limited and inconsistent evidence, primarily from cross-sectional studies, linking mycotoxins to adverse birth outcomes. This study investigates the potential role of maternal dietary exposure to multiple mycotoxins in the development of several adverse pregnancy and birth outcomes. We analyzed data from 436 singleton pregnancies enrolled in a prospective cohort study in the rural Habiganj district, Bangladesh, between July 2018 and November 2019. Thirty-five urinary mycotoxin biomarkers were quantified using liquid chromatography coupled with tandem mass spectrometry and used to estimate dietary mycotoxin exposure. Multivariable regression models, adjusted for potential confounding and clustering, were fitted to assess the associations between maternal exposure to frequently occurring mycotoxins (ochratoxin A-OTA, citrinin- CIT, and Deoxynivalenol- DON) and pregnancy loss, preterm birth (PTB), low birth weight (LBW), born small-for-gestational-age (SGA) and small-vulnerable newborn. The results indicate that only in 16 of 436 pregnancies (4%) were urine samples free from all investigated mycotoxins. Biomarkers for six major mycotoxins were detected in the urine samples. OTA (95%), CIT (61%), and DON (6%) were most frequently detected, with at least two mycotoxins co-occurring in the majority of women (63%). There was evidence that maternal dietary intake of OTA was associated with higher odds of having an LBW baby, with the odds increasing in a dose-dependent manner. We found no evidence of associations between pregnancy loss, PTB, SGA, small-vulnerable newborns, and maternal dietary exposure to OTA, CIT, and DON, albeit with large confidence intervals, so findings are consistent with protective as well as large harmful effects. Exposure to multiple mycotoxins during pregnancy is widespread in this rural community and represents a health risk for mothers and babies. Tailored public health policies and interventions must be implemented to reduce mycotoxin exposure to the lowest possible level.

Negotiating Autonomy: The Linkages between Intimate Partner Violence, Women’s Paid Work Status and Birth Outcomes

Maternal and child health is severely impacted by adverse birth outcomes leading to a public health concern. A whole host of socioeconomic factors are instrumental in determining birth outcomes. Importantly, there is an intricate relationship between women’s autonomy, the perpetration of intimate partner violence in households, women’s paid work status and their consequent impact on birth outcomes. Noting this, we ask how intimate partner violence and women’s work status interact and how women’s ‘autonomy’ is negotiated to mitigate adverse birth outcomes such as miscarriage, abortion, stillbirth, low birth weight and preterm birth. We use the nationally representative NFHS-5 data for India and use multiple correspondence analyses to create an index of women’s autonomy, and multinomial logistic regression has been used to determine the relation. Women’s working status in association with the perpetration of intimate partner violence contributes significantly to adverse birth outcomes. The study found that mitigation of adverse birth outcomes, which is necessary for bringing about improvements in maternal and child health, is contingent on a multiplicity of social factors, which requires redressal in association to ensure a reduction in adverse birth outcomes.

Spatial variation and inequities in antenatal care coverage in Kenya, Uganda and mainland Tanzania using model-based geostatistics: a socioeconomic and geographical accessibility lens

BACKGROUND

Pregnant women in sub-Saharan Africa (SSA) experience the highest levels of maternal mortality and stillbirths due to predominantly avoidable causes. Antenatal care (ANC) can prevent, detect, alleviate, or manage these causes. While eight ANC contacts are now recommended, coverage of the previous minimum of four visits (ANC4+) remains low and inequitable in SSA.

METHODS

We modelled ANC4+ coverage and likelihood of attaining district-level target coverage of 70% across three equity stratifiers (household wealth, maternal education, and travel time to the nearest health facility) based on data from malaria indicator surveys in Kenya (2020), Uganda (2018/19) and Tanzania (2017). Geostatistical models were fitted to predict ANC4+ coverage and compute exceedance probability for target coverage. The number of pregnant women without ANC4+ were computed. Prediction was at 3 km spatial resolution and aggregated at national and district -level for sub-national planning.

RESULTS

About six in ten women reported ANC4+ visits, meaning that approximately 3 million women in the three countries had  20,000 women having

CONCLUSIONS

These findings will be invaluable to policymakers for annual appropriations of resources as part of efforts to reduce maternal deaths and stillbirths.

Effects of HIV Infection on Pregnancy Outcomes Among Women Attending Antenatal Care in Referral Hospitals of the Amhara Regional State, Ethiopia: A Prospective Cohort Study

Background

Human immunodeficiency virus (HIV) has remained to be a significant public health problem worldwide mainly affecting women. Despite a 2 to 3 times higher risk of adverse pregnancy outcomes, around 2 million HIV positive women give birth each year globally. However, there is a dearth of evidences in Ethiopia about the effect of maternal HIV infection on pregnancy outcomes where adverse birth outcomes are still a significant health problem. This study is, therefore, aimed to examine the effect of HIV on the risk of adverse pregnancy outcomes in Amhara Regional State, Ethiopia.

Methods

A prospective cohort study was conducted among 704 pregnant women (352 women with HIV and 352 women without HIV infection). Systematic random sampling technique was employed to select the study participants. Data on socio-demographic, obstetric, clinical, as well as behavioral and psychosocial characteristics were collected using a validated tool. Data on the outcome variables were also collected following delivery. Modified Poisson regression was employed to estimate the relative risk (RR) of HIV on low birth weight (LBW), preterm birth, and still birth at 95% confidence level. Attributable fraction (AF) was used to report the impact of HIV infection on pregnancy outcomes.

Results

Of the total 704 pregnant women enrolled for the study, 96.3% (678) completed the study. The mean age of the study participants was 30.8 (SD ± 5.4) for HIV positive and 27 (SD ± 5.4) for HIV negative women. The cumulative incidence of low birth weight, preterm birth, and stillbirth were 21.4%, 9.4%, and 4.1%, respectively. The incidence of LBW was 24.7% among HIV positive and 17.8% among HIV negative women. The incidence of preterm birth was 10.7% among HIV positive and 7.9% among HIV negative women. And the incidence of stillbirth was 3.7% and 4.6% among HIV positive and those HIV negative women. New-borns from women with HIV infection had a higher risk of low birth weight and preterm birth than those HIV negative women (Adjusted Relative Risk (ARR) = 1.47; 95% CI: 1.06-2.03) and (ARR = 1.74; 95% CI: 1.08-2.79), respectively. The attributable risk of HIV on low birth weight was 32% (Attributable Fraction (AF) = 32%, 95% CI: 23-46%), and 43% (AF = 43%, 95% CI: 23-46%) for preterm birth.

Conclusion

Maternal HIV infection increased the risk of low birth weight and preterm birth. This implies due attention is required while providing maternal health services primarily antenatal care and delivery services. These services should be aimed at reducing adverse pregnancy outcomes with more attention given to women with HIV infection. Moreover, reinforcement of HIV prevention intervention strategies should be considered at all levels.

Assessment of the adverse pregnancy outcomes and its associated factors among deliveries at Debre Berhan Comprehensive Specialized Hospital, Northeast Ethiopia

Background

Adverse pregnancy outcomes are the main causes of maternal and neonatal morbidity and mortality and long-term physical and psychological sequels in low- and middle-income countries, particularly in Africa and Asia. In Ethiopia, maternal mortality remained high despite the country’s maximum effort. This study aimed to assess adverse pregnancy outcomes and associated factors among deliveries at Debre Berhan Comprehensive Specialized Hospital, Northeast Ethiopia.

Methods

A retrospective cross-sectional study was done among deliveries at Debre Berhan Comprehensive Specialized Hospital from January 1, 2017, to December 31, 2018. The data was collected using a structured and pre-tested questionnaire by reviewing labor and delivery service log books and admission or discharge registration books. The data were entered into a Microsoft Excel spreadsheet and analyzed using SPSS version 25. Logistic regression analysis was computed to identify independent predictors of pregnancy complications.

Result

In this study, the magnitude of adverse pregnancy outcomes was 28.3%, 95% CI (25.7–30.9). The most frequently recorded obstetric complications were obstructed labor (7.4%), retained placenta (5.3%), and hypertensive disorders of pregnancy (2.4%). Whereas stillbirths (10%), malpresentation (3%), and prematurity (2.3%) frequently occurred fetal/neonatal complications. There were 29 maternal deaths and the possible causes of death were obstructed labor (51.7%), hemorrhage (44.7%), eclampsia (24.1%), and sepsis (6.9%). Home delivery (AOR (CI = 4.12 (2.30–7.15) and low birth weight (AOR (CI = 1.63 (1.36–1.96) were significant associates of adverse pregnancy outcomes.

Conclusion

The magnitude of adverse pregnancy outcomes was high. Obstructed labor, retained placenta, hypertension in pregnancy, malpresentation, prematurity, and stillbirth are the commonest adverse pregnancy outcomes. Place of delivery and birth weight were independent predictors of adverse pregnancy outcomes. Institutional delivery, early detection and management of complications, and adequate nutrition and weight gain during pregnancy should be encouraged to minimize the risk of adverse pregnancy outcomes.

The Impacts of Prenatal Mental Health Issues on Birth Outcomes during the COVID-19 Pandemic: A Scoping Review

Background: The severity of the COVID-19 pandemic is likely to exacerbate mental health problems during the prenatal period and increase the risk of adverse birth outcomes. This review assessed the published literature related to the impacts of prenatal mental health issues on birth outcomes during the COVID-19 pandemic. Methods: This scoping review was conducted using PROSPERO, Cochrane Library, OVID Medline, Ovid EMBASE, OVID PsycInfo, EBSCO CINAHL, and SCOPUS. The search was conducted using controlled vocabulary and keywords representing the concepts “COVID19”, “mental health” and “birth outcomes”. The main inclusion criteria were peer-reviewed published articles from late 2019 to the end of July 2021. Results and Discussion: After removing duplicates, 642 articles were identified, of which two full texts were included for analysis. Both articles highlighted that pregnant women have experienced increasing prenatal mental health issues during the COVID-19 pandemic and, further, increased the risk of developing adverse births. This scoping review highlighted that there is a lack of research on the impact of prenatal mental health issues on birth outcomes during the pandemic. Conclusion: Given the severity of the COVID-19 pandemic and the burdens of prenatal mental health issues and adverse birth outcomes, there is an urgent need to conduct further research.

Multiple mycotoxin exposure during pregnancy and risks of adverse birth outcomes: a prospective cohort study in rural Ethiopia

INTRODUCTION

Mycotoxin exposure during pregnancy has been associated with adverse birth outcomes in low- and middle-income countries. The evidence, however, is inconsistent and mainly limited to the assessment of a single mycotoxin. We assessed biomarkers of exposure to multiple mycotoxins during pregnancy and their associations with adverse birth outcomes in rural Ethiopia.

METHODS

We analyzed data from 579 pregnant women between 8 and 24 weeks of completed gestation enrolled in a prospective cohort study. Serum mycotoxin concentrations were determined using liquid chromatography coupled with tandem mass spectrometry. Multivariable linear probability models, adjusted for potential confounding factors and multiple comparisons, were fitted to assess the associations between mycotoxin exposure and small for gestational age and preterm birth. We applied principal component analysis to reduce the dimensionality of biomarker data from several taxonomic mycotoxin groups.

RESULTS

All pregnant women were co-exposed to at least five mycotoxins, and one pregnant woman was co-exposed to 27 mycotoxins. Fumonisins (FB), i.e., FB₂, FB₃, FB₁, and tenuazonic acid were the most frequently identified mycotoxins in 98.8, 95.3, 93.3, and 81.4% of the samples respectively. Deoxynivalenol was detected in 38.7%, nivalenol in 50.1%, ochratoxin α in 67.9%, and zearalenone in 50.9% of the serum samples. After adjustment, we found no statistically significant (all P ≥ 0.05) associations between mycotoxin exposures and birth outcomes.

CONCLUSIONS

Despite our study providing no evidence for relationships between mycotoxin biomarkers and adverse birth outcomes, our findings do indicate an extensive presence of multiple mycotoxin exposure among pregnant women. Public health policies and nutrition-sensitive interventions must ensure exposure to mycotoxins is reduced in rural Ethiopia.

Adverse Perinatal Outcomes Among Grand Multiparous and Low Multiparous Women and Its Associated Factors in North Shewa Zone Public Hospitals: The Role of Parity

Background

Adverse perinatal outcomes are the major cause of neonatal morbidity, mortality, and long-term physical and psychological consequences. Contradicting evidence across studies was reported about the impact of grand multiparity on adverse perinatal outcomes. Older literature reported increased incidence of perinatal complications in grand multiparas, but, recent reports failed to support this finding. In addition, there is a paucity of comparative studies on perinatal outcomes. Thus, the study aimed to compare the perinatal outcomes in grand multiparous (GM) and low multiparous (LM) women who give birth in North Shewa Zone Public Hospitals, Ethiopia, 2021.

Methods

A comparative cross-sectional study was done among 540 (180 GM and 360 LM) women from January 1 to March 30, 2021. The data were collected using a structured and pre-tested questionnaire through interviews and reviewing patient charts. SPSS version 25 was used for data analysis. The data were entered using Epi-Data version 4.6. The Hosmer–Lemeshow goodness-of-fit was applied to test for model fitness. The statistical significance level was declared at a p-value of ≤0.05.

Results

In this study, the prevalence of adverse perinatal outcomes was 14.1% (95% CI: 10.9–17.2). Stillbirth/IUFD (33.3%) and low APGAR score (60%) were frequently occurred complications in grand multiparas. Nevertheless, meconium aspiration (26%), admission to NICU (65.2%), macrosomia (61%), and prematurity (52.2%) were higher in low multiparous women. Age above 35 years (AOR (CI) = 2.61 (1.23–5.53)), rural residence (AOR (CI) = 8.31 (3.05–22.6)), being a government employee (AOR (CI) = 0.19 (0.05–0.69)), lack of antenatal care (AOR (CI) = 9.76 (3.03–31.5)), and previous pregnancy complications (AOR (CI) = 3.10 (1.63–5.90)) were significant predictors of adverse perinatal outcomes. However, parity did not show a statistically significant association with perinatal outcomes.

Conclusion

Maternal age, residence, occupation, lack of antenatal care, and previous pregnancy complications were significant associates of perinatal outcome. There was no statistically significant difference in perinatal outcome between GM and LM women. Socio-economic development, good antenatal care, and early identification and treatment of complications are needed regardless of parity.
