Determinants of stillbirth in Bonga General and Mizan Tepi University Teaching Hospitals southwestern Ethiopia, 2016: a case–control study

This study aimed to identify determinants of still birth in selected hospitals of Southwestern Ethiopia. A total 540 charts registered for maternal health services utilization were included in the analysis with proportion of case to control ratio of one to three (135 cases, 405 control). Women who attended antenatal care were 40% less risk for stillbirth compared to those who did not attend antenatal care (AOR = 0.6, 95% CI 0.39, 0.94). Those who had labor length ≥ 24 h were 2.4 times at risk to have still birth than ≤ 24 h (AOR = 2.44, 95% CI 1.4, 4.26). Women who developed uterine rupture were about 5 times more likely to have still birth than did not develop the complication (AOR = 4.9, 95% CI 1.67, 14.35). Women who have different antenatal risks were 4.5 times more likely to have still birth (AOR = 4.58, 95% CI 1.45, 14.48). Weight of baby ≥ 2.5 kg were 73% less likely to still birth when compared to counterparts (AOR = 0.27, 95% CI 0.14, 0.53).
