Risk Factors of Stillbirth Among Women Who Gave Birth in Amhara Region Referral Hospitals, Ethiopia, in 2019: A Case-Control Study

Determinants of stillbirth among women who delivered in hospitals of North Wollo Zone, Northeast Ethiopia: A case-control study

BACKGROUND

Stillbirth is a silent tragedy that shatters the lives of women, families, and nations. Though affecting over 2 million infants globally in 2019, it remains overlooked, with no specific targets dedicated to its reduction in the sustainable development goals. Insufficient knowledge regarding the primary risk factors contributing to stillbirths hinders efforts to reduce its occurrence. Driven by this urgency, this study focused on identifying the determinants of stillbirth among women giving birth in hospitals across North Wollo Zone, Northeast Ethiopia.

METHODOLOGY

This study employed an institution-based unmatched case-control design, involving a randomly selected sample of 412 women (103 cases and 309 controls) who gave birth in hospitals of North Wollo Zone. Data were collected using a structured data extraction checklist. Data entry was conducted using Epi-data version 3.1, and analysis was performed using SPSS version 25.0. Employing a multivariable logistic regression model, we identified independent predictors of stillbirth. The level of statistical significance was declared at a p-value < 0.05.

RESULTS

Our analysis revealed several critical factors associated with an increased risk of stillbirth. Women who experienced premature rupture of membranes (AOR = 5.53, 95% CI: 2.33-9.94), induced labor (AOR = 2.24, 95% CI: 1.24-4.07), prolonged labor exceeding 24 hours (AOR = 3.80, 95% CI: 1.94-7.45), absence of partograph monitoring during labor (AOR = 2.45, 95% CI: 1.41-4.26) were all significantly associated with increased risk of stillbirth. Preterm birth (AOR = 3.46, 95% CI: 1.87-6.39), post-term birth (AOR = 3.47, 95% CI: 1.35-8.91), and carrying a female fetus (AOR = 1.81, 95% CI: 1.02-3.22) were at a higher risk of stillbirth.

CONCLUSION

These findings highlight the importance of early intervention and close monitoring for women experiencing premature rupture of membranes, prolonged labor, or induced labor. Additionally, consistent partograph use and enhanced prenatal care for pregnancies at risk of preterm or post-term birth could potentially contribute to reducing stillbirth rates and improving maternal and neonatal outcomes. Further research is needed to investigate the underlying mechanisms behind the observed association between fetal sex and stillbirth risk.

Incidence and determinants of perinatal mortality in five urban hospitals in Dar es Salaam, Tanzania: a cohort study with an embedded case-control analysis

INTRODUCTION

Tanzania has one of the highest burdens of perinatal mortality, with a higher risk among urban versus rural women. To understand the characteristics of perinatal mortality in urban health facilities, study objectives were: I. To assess the incidence of perinatal deaths in public health facilities in Dar es Salaam and classify these into a) pre-facility stillbirths (absence of fetal heart tones on admission to the study health facilities) and b) intra-facility perinatal deaths before discharge; and II. To identify determinants of perinatal deaths by comparing each of the two groups of perinatal deaths with healthy newborns.

METHODS

This was a retrospective cohort study among women who gave birth in five urban, public health facilities in Dar es Salaam. I. Incidence of perinatal death in the year 2020 was calculated based on routinely collected health facility records and the Perinatal Problem Identification Database. II. An embedded case-control study was conducted within a sub-population of singletons with birthweight ≥ 2000 g (excluding newborns with congenital malformations); pre-facility stillbirths and intra-facility perinatal deaths were compared with 'healthy newborns' (Apgar score ≥ 8 at one and ≥ 9 at five minutes and discharged home alive). Descriptive and logistic regression analyses were performed to explore the determinants of deaths.

RESULTS

A total of 37,787 births were recorded in 2020. The pre-discharge perinatal death rate was 38.3 per 1,000 total births: a stillbirth rate of 27.7 per 1,000 total births and an intra-facility neonatal death rate of 10.9 per 1,000 live births. Pre-facility stillbirths accounted for 88.4% of the stillbirths. The case-control study included 2,224 women (452 pre-facility stillbirths; 287 intra-facility perinatal deaths and 1,485 controls), 99% of whom attended antenatal clinic (75% with more than three visits). Pre-facility stillbirths were associated with low birth weight (cOR 4.40; (95% CI: 3.13-6.18) and with maternal hypertension (cOR 4.72; 95% CI: 3.30-6.76). Intra-facility perinatal deaths were associated with breech presentation (aOR 40.3; 95% CI: 8.75-185.61), complications in the second stage (aOR 20.04; 95% CI: 12.02-33.41), low birth weight (aOR 5.57; 95% CI: 2.62-11.84), cervical dilation crossing the partograph's action line (aOR 4.16; 95% CI:2.29-7.56), and hypertension during intrapartum care (aOR 2.9; 95% CI 1.03-8.14), among other factors.  CONCLUSION: The perinatal death rate in the five urban hospitals was linked to gaps in the quality of antenatal and intrapartum care, in the study health facilities and in lower-level referral clinics. Urgent action is required to implement context-specific interventions and conduct implementation research to strengthen the urban referral system across the entire continuum of care from pregnancy onset to postpartum. The role of hypertensive disorders in pregnancy as a crucial determinant of perinatal deaths emphasizes the complexities of maternal-perinatal health within urban settings.

Determinants of stillbirths in sub-Saharan Africa: A systematic review

BACKGROUND

Sub-Saharan African (SSA) countries have high stillbirth rates compared with high-income countries, yet research on risk factors for stillbirth in SSA remain scant.

OBJECTIVES

To identify the modifiable risk factors of stillbirths in SSA and investigate their strength of association using a systematic review.

SEARCH STRATEGY

CINAHL Plus, EMBASE, Global Health and MEDLINE databases were searched for literature.

SELECTION CRITERIA

Observational population- and facility-level studies exploring stillbirth risk factors, published in 2013-2019 were included.

DATA COLLECTION AND ANALYSIS

A narrative synthesis of data was undertaken and the potential risk factors were classified into subgroups.

MAIN RESULTS

Thirty-seven studies were included, encompassing 20 264 stillbirths. The risk factors were categorised as: maternal antepartum factors (0-4 antenatal care visits, multiple gestations, hypertension, birth interval of >3 years, history of perinatal death); socio-economic factors (maternal lower wealth index and basic education, advanced maternal age, grand multiparity of ≥5); intrapartum factors (direct obstetric complication); fetal factors (low birthweight and gestational age of <37 weeks) and health systems factors (poor quality of antenatal care, emergency referrals, ill-equipped facility). The proportion of unexplained stillbirths remained very high. No association was found between stillbirths and body mass index, diabetes, distance from the facility or HIV.

CONCLUSIONS

The overall quality of evidence was low, as many studies were facility based and did not adjust for confounding factors. This review identified preventable risk factors for stillbirth. Focused programmatic strategies to improve antenatal care, emergency obstetric care, maternal perinatal education, referral and outreach systems, and birth attendant training should be developed. More population-based, high-quality research is needed.

Tella intake among pregnant and lactating mothers: may it affect child growth?

Alcohol abuse among women is a public health importance that may impair prenatal and postnatal growth. Tella is among the most common homemade alcoholic beverages in rural Ethiopia, but little is known about the magnitude of tella intake during pregnancy and lactation or its effects on child growth. The present study investigated associations between maternal tella intake and the growth of their children. A cross-sectional mixed-methods study was conducted with mothers (n 228) and their 12–36-month-old children and with key informants (n 12). Tella intake during most recent pregnancy and lactation was estimated retrospectively by glasses per drinking event and frequency of events. Nearly 80 % of mothers had consumed some amount of tella during their most recent pregnancy and lactation. Furthermore, 72 % of children had tasted or drunk tella at some time during their life. Stunting was 42 % and was significantly associated with maternal tella consumption at least every other day during pregnancy (adjusted odds ratio (AOR) 4⋅97, 95 % confidence interval (CI) 2⋅20, 11⋅25), male sex (AOR 2⋅31, 95 % CI 1⋅27, 4⋅19), two or more under-5-year-old children in the household (AOR 3⋅52, 95 % CI 1⋅49, 8⋅33) and family size >5 (AOR 1⋅84, 95 % CI 1⋅01, 3⋅36). Underweight was 24⋅6 % and was associated with the child drinking tella with their mother (AOR 4⋅23, 95 % CI 1⋅99, 8⋅97), being male (AOR 3⋅73, 95 % CI 1⋅73, 7⋅94), having ≥3 diarrhoeal episodes in the last 3 months (AOR 11⋅83, 95 % CI 4⋅22, 33⋅14) and being in the older age group (AOR 2⋅98, 95 % CI 1⋅09, 8⋅13). The associations between tella intake and child growth suggest the need to mitigate the effects of tella on child anthropometry.
