Determinants of obstructed labor among women attending intrapartum care in Amhara Region, Northwest Ethiopia: A hospital-based unmatched case-control study.

Abstract

Objectives:maternal and neonatal mortality in Ethiopia is a major reproductive health problem. Obstructed labor is one of the leading causes of maternal, fetal, and neonatal morbidity in developing countries. The evidence regarding its determinants at the tertiary level of care is sparse. Therefore, this study aimed to study the determinants of obstructed labor among women attending intrapartum care in Amhara region referral hospitals.Methods:A Hospital-based unmatched case-control study was conducted from March 1stto August 30, 2017. Cases were women whose labor was obstructed (n = 270), and controls were women whose labor was not obstructed (n = 540). Both cases and controls were selected randomly, and a proportional to size allocation was made to the referral hospitals selected for the study. A binary and a multivariable logistic regression model was computed to identify the determinant factors at 95% CI.Results:The mean age of the study participants was 27.66 years (27.4 ± 5.44 for cases and 28.15 ± 6.16 for controls), ranging between 16 and 45 years. Relatively, higher proportions of cases than controls were unable to read and write (58.5%) and were urban residents (53.7%). Distance from hospital, distance from health center, mothers inability to read and write, mothers primary level of education, more than 28 weeks of gestation at the first visit of antenatal care, 37 to 42 weeks at admission, above 42 weeks at admission, women of a merchant spouse, and history of pregnancy-related complications were the positive determinants of obstructed labor. However, mothers whose gestational age was 16 to 28 weeks at the first antenatal care visit were 62% less likely to be exposed to obstructed labor.Conclusions:Obstetric, service-related, and system factors were predictors of obstructed labor. Improving women’s literacy status, health service access, and utilization will help reduce obstructed labor.
