ABSTRACT
OBJECTIVE:
This study aimed to investigate the incidence of and risk factors for stillbirth in an Indian population.METHODS:
We conducted a secondary data analysis of a hospital-based cohort from the Maternal and Perinatal Health Research collaboration, India (MaatHRI), including pregnant women who gave birth between October 2018-September 2023. Data from 9823 singleton pregnancies recruited from 13 hospitals across six Indian states were included. Univariable and multivariable Poisson regression analysis were performed to examine the relationship between stillbirth and potential risk factors. Model prediction was assessed using the area under the receiver-operating characteristic (AUROC) curve.RESULTS:
There were 216 stillbirths (48 antepartum and 168 intrapartum) in the study population, representing an overall stillbirth rate of 22.0 per 1000 total births (95% confidence interval [CI] 19.2-25.1). Modifiable risk factors for stillbirth were receiving less than four antenatal check-ups (adjusted relative risk [aRR] 1.75, 95% CI 1.25-2.47), not taking any iron and folic acid supplementation during pregnancy (aRR 7.23, 95% CI 2.12-45.33) and having severe anemia in the third trimester (aRR 3.37, 95% CI 1.97-6.11). Having pregnancy/fetal complications such as hypertensive disorders of pregnancy (aRR 1.59, 95% CI 1.03-2.36), preterm birth (aRR 4.41, 95% CI 3.21-6.08) and birth weight below the 10th percentile for gestational age (aRR 1.35, 95% CI 1.02-1.79) were also associated with an increased risk of stillbirth. Identified risk factors explained 78.2% (95% CI 75.0%-81.4%) of the risk of stillbirth in the population.CONCLUSION:
Addressing potentially modifiable antenatal factors could reduce the risk of stillbirths in India.Key words
