Abstract:
Obstructed labour is one of the most common preventable causes of maternal and prenatal
morbidity and mortality in developing countries. The most frequent cause of obstructed labour is
cephalo-pelvic disproportion- a mismatch between the fetal head and the mother’s pelvic brim. The fetus
may be large in relation to the maternal pelvic brim, such as the fetus of a diabetic woman, or the pelvis
may be contracted, which is more common when malnutrition is prevalent.
Objective: The aim of this study is to assess the prevalence and factors associated with obstructed
labour among women who delivered at hospitals of western part of SNNPR, Ethiopia. From March 1-30,
2020.
Methodology:- Institutional based cross-sectional study design was employed on 742 women who
deliver in western part of SNNPR public hospitals. All public hospitals were covered purposively then
proportional allocation was done for each hospital to get study participants based on number of
delivering mothers in the hospital. All pregnant women who came for delivery service in the hospital
were enrolled continuously. The data were collected by face to face interview and secondary data review
by using structured and pre-tested questionnaire. Data was entered to EpiData Manager Version 4.0
software and SPSS version 20 was used for analysis. Bivariate logistic Regresion was used to determine
the association between predictors and outcome variable. The multivariate analysis adjusted odd ratio
with 95%confidence level was used to determine associated factors with obstructed labour. For all the
statistical tests, p<0.05 was considered as statistically significant.
Result: The prevalence of obstructed labor among study participants was found to be 111 (15.8%,
95%CI, 13.1%, 18.5%). The risks of obstructed labour was significantly associated with age <20 years
(AOR; 8, 95% CI 2.98, 22.12), duration of labor >24 hours. (AOR: 4.4, 95% CI 2.56,7.67) and previous
history of any complications experienced following labour and delivery (AOR;4.2,95% CI 2.63,6.98).
Conclusion: The study shows that prevalence of obstructed labour was 15.8%. Maternal age, duration
of labour and previous history of any complications experienced following labour and delivery were
significantly associated with obstructed labou
