Different adverse perinatal outcomes observed in overweight/obese women, of those caesarean section occurred frequently. In Ethiopia, the national caesarean section and overweight/obesity rate among reproductive-aged women increased tremendously. Therefore, we intend to assess the association between overweight/obesity with caesarean section in Ethiopia.Method The data were extracted from the 2016 Ethiopia Demographic and Health Survey in nine regions and two city administrations. A stratified two-stage random sampling design was used to collect data. The exposure variable was overweight/obesity, and the outcome variable was a caesarean section. The final analytical sample consisted of 6928 participants. SPSS V.23 was used to analyse the data. Descriptive statistics and cross-tabulation were performed to describe the study variables. Univariable and multivariable logistic regression models were regressed.Results The prevalence of caesarean section among women aged between 15–49 years old who gave birth in the last 5 years was 245 (3.54%). The occurrence of caesarean section among overweight/obese women was 2.05 higher as compared with normal-weight women (AOR: 2.05, 95% CI: 1.09 - 3.83).Conclusion and recommendation Promoting weight reduction programmes throughout the country would have a greater contribution to reduce caesarean section rate and health cost, and to improve the health of the mother.All data relevant to the study are included in the article or uploaded as supplemental information.
