This study sought to identify the rate of caesarean section and associated factors in two districts in rural southern Ghana. Methods: Pregnancy, birth, and socio-demographic information of 4948 women who gave birth between 2011 and 2013 were obtained from the database of Dodowa Health and DemographicSurveillanceSystem.TherateofC-sectionwas determined and the associations between independent and dependent variables were explored using logistic regression. TheanalysesweredoneinSTATA14.2 at 95% confidence interval. Results: The overall C-section rate for the study period was 6.59%. Women aged 30–34 years were more than twice likely to have C-section compared to those < 20 year (OR: 2.16, 95% CI: 1.20–3.90). However, women aged 34 years and above were more than thrice likely to undergo C-section compared to those < 20 year (OR: 3.73, 95% CI: 1.45–5.17). The odds of having C-section was 65 and 79% higher for participants with Primary and Junior High level schooling respectively (OR: 1.65, 95% CI: 1.08–2.51, OR:1.79, 95%CI: 1.19–2.70). The likelihood of having C-section delivery reduced by 60, 37, and 35% for women with parities 2, 3 and 3+ respectively (OR:0.60, 95% CI: 0.43–0.83, OR: 0.37, 95% CI: 0.25–0.56, OR:0.35, 95% CI: 0.25–0.54). There were increased odds of 36, 52, 83% for women who belong to poorer, middle, and richer wealth quintiles respectively (OR: 1.36, 95%CI: 0.85–2.18, OR: 1.52, 95% CI: 0.97–2.37, OR: 1.83, 95% CI: 1.20–2.80). Participants who belonged to the richest wealth quintile were more than 2 times more likely to have C-section delivery (OR: 2.14, 95%CI: 1.43–3.20). The odds of having C-section delivery reduced by 76% for women from Ningo-Prampram district (OR: 0.76, 95% CI: 0.59.0.96). Women whose household heads have Junior High level and above of education were 45% more likely to have C-section delivery (OR: 1.45, 95% CI: 1.09–1.93). Conclusion: Age of mother, educational level, parity, household socioeconomic status, district of residence, and level of education of household head are associated with caesarean section delivery.
