Perinatal Asphyxia and Its Associated Factors among Live Births in the Public Health Facilities of Bahir Dar City, Northwest Ethiopia, 2021

Determinants of birth asphyxia in urban south Ethiopia

Birth asphyxia is a well-known cause of neonatal mortality, and the survivors suffer from long-lasting sequels such as seizures, intellectual disabilities, and motor disorders that are great challenges for newborns. Elucidating the determinants of birth asphyxia helps implement evidence-based practice in the local context. Thus, this study aimed at elucidating the determinants of birth asphyxia in urban south Ethiopia. A community-based unmatched nested case-control study was conducted on a cohort of 2548 pregnant women who were followed up until delivery in urban areas of Hadiya Zone, south Ethiopia. All newborns who experienced birth asphyxia (n = 118) were taken as cases. Newborns who were randomly selected from the risk-set (n = 472) were taken as controls (those without birth asphyxia). A binary logistic regression was done using R software. Induction of labor [AOR = 2.98, 95% CI: 1.20, 7.42], prolonged labor [AOR = 2.12, 95% CI: 1.02, 4.37], delivery through cesarean section [AOR = 3.81, 95% CI: 1.67, 8.72], instrumental delivery [AOR = 3.91, 95% CI: 1.72, 8.89], and low birth weight [AOR = 6.52, 95% CI: 3.40, 12.51] were determinants of birth asphyxia. Asphyxia during birth was mainly related to obstetric care and maternal nutrition, highlighting the need to pay attention during the course of labor and maternal nutrition during pregnancy. This study might have selection bias and loss of power so careful interpretation of the results is needed.

Magnitude of neonatal asphyxia and its predictors among newborns at public hospitals of Wolaita Zone in Southern Ethiopia, 2023

BACKGROUND

Neonatal asphyxia is one of preventable causes of neonatal mortality throughout the world. It could be improved by early detection and control of the underlying causes. However, there was lack of evidence on it in the study setting. Thus, the aim of this study was to assess the magnitude and predictors of neonatal asphyxia among newborns at public hospitals of Wolaita Zone in Southern Ethiopia.

METHOD

A facility-based cross-sectional study was done among 330 mothers with neonates in selected public hospitals. A systematic random sampling technique was used to select the study participants. Data were collected through an interviewer-administered questionnaire and checklist. The collected data were entered into EpiData version 4.6 and exported to SPSS version 26 for analysis. Logistic regression was fitted to examine the association between explanatory variables and outcome variable. In multivariable logistic regression, AOR with 95% CI was reported, and p < 0.05 was used to declare statistically significant variables.

RESULTS

The magnitude of neonatal asphyxia was 26.4% with 95% CI: (21.8, 30.9). In multivariable logistic regression analysis primiparity (AOR = 2.63 95%CI 1.47, 4.72), low-birth-weight (AOR = 3.45 95%CI 1.33, 8.91), preterm birth (AOR = 3.58 95%CI 1.29, 9.92), and premature rupture of membranes (AOR = 5.19 95%CI 2.03, 13.26) were factors significantly associated with neonatal asphyxia.

CONCLUSIONS

In this study, the magnitude of neonatal asphyxia was high. From the factors, premature rapture of the membrane, parity, birth weight of the newborn, and gestational age at birth were significantly associated with neonatal asphyxia. Attention should be given to early detection and prevention of neonatal asphyxia from complicated labor and delivery.

Predictors of Birth Asphyxia Among Newborns in Public Hospitals of Eastern Amhara Region, Northeastern Ethiopia, 2022

Background

Ethiopia ranked fourth in the world in terms of neonatal mortality rates, with birth asphyxia accounting for the majority of neonatal deaths.

Objective

This study aimed to determine the prevalence of birth asphyxia and associated factors among newborns delivered in government hospitals of the Eastern Amhara region, Northeastern Ethiopia, 2022.

Methods

A hospital-based cross-sectional study was conducted in 4 government hospitals between March 10, 2022, and May 8, 2022. The subjects in the study were selected using a systematic random sampling technique. Face-to-face interviews and chart reviews were used to collect the data. The association was discovered through multivariate logistic regression analysis.

Result

In this study, the prevalence of birth asphyxia was 13.1% (48) of the total 367 newborns. Mothers who could not read and write (AOR = 9.717; 95% CI = 3.06, 10.857); infants born with low birth weight (AOR = 2.360; 95% CI = 1.004, 5.547); primipara mothers (AOR = 5.138; 95% CI = 1.060, 26.412); mothers with less than 37 weeks of gestation (AOR = 4.261; 95% CI = 1.232, 14.746); and caesarian section delivery (AOR = 2.444; 95% CI = 1.099, 5.432) were predictors of birth asphyxia.

Conclusion

The magnitude of birth asphyxia has managed to remain a health concern in the study setting. As a result, special attention should be paid to uneducated and primi-mothers during antenatal care visits, and prematurity and caesarian section delivery complication reduction efforts should be bolstered to prevent birth asphyxia and its complications.

Factors associated with birth asphyxia among term singleton births at two referral hospitals in Northern Uganda: a cross sectional study

Background

Birth asphyxia is one of the leading causes of neonatal mortality worldwide. In Uganda, it accounts for 28.9% of all neonatal deaths. With a view to inform policy and practice interventions to reduce adverse neonatal outcomes, we aimed to determine the prevalence and factors associated with birth asphyxia at two referral hospitals in Northern Uganda.

Methods

This was a cross-sectional study, involving women who gave birth at two referral hospitals. Women in labour were consecutively enrolled by the research assistants, who also attended the births and determined Apgar scores. Data on socio-demographic characteristics, pregnancy history and care during labour, were obtained using a structured questionnaire. Participants were tested for; i) malaria (peripheral and placental blood samples), ii) syphilis, iii) white blood cell counts (WBC), and iv) haemoglobin levels. The prevalence of birth asphyxia was determined as the number of newborns with Apgar scores < 7 at 5 min out of the total population of study participants. Factors independently associated with birth asphyxia were determined using multivariable logistic regression analysis and a p-value < 0.05 was considered statistically significant.

Results

A total of 2,930 mother-newborn pairs were included, and the prevalence of birth asphyxia was 154 [5.3% (95% confidence interval: 4.5- 6.1)]. Factors associated with birth asphyxia were; maternal age ≤ 19 years [adjusted odds ratio (aOR) 1.92 (1.27–2.91)], syphilis infection [aOR 2.45(1.08–5.57)], and a high white blood cell count [aOR 2.26 (1.26–4.06)], while employment [aOR 0.43 (0.22–0.83)] was protective. Additionally, referral [aOR1.75 (1.10–2.79)], induction/augmentation of labour [aOR 2.70 (1.62–4.50)], prolonged labour [aOR 1.88 (1.25–2.83)], obstructed labour [aOR 3.40 (1.70–6.83)], malpresentation/ malposition [aOR 3.00 (1.44–6.27)] and assisted vaginal delivery [aOR 5.54 (2.30–13.30)] were associated with birth asphyxia. Male newborns [aOR 1.92 (1.28–2.88)] and those with a low birth weight [aOR 2.20 (1.07–4.50)], were also more likely to develop birth asphyxia.

Conclusion

The prevalence of birth asphyxia was 5.3%. In addition to the known intrapartum complications, teenage motherhood, syphilis and a raised white blood cell count were associated with birth asphyxia. This indicates that for sustained reduction of birth asphyxia, appropriate management of maternal infections and improved intrapartum quality of care are essential.
