Factors associated with unintended pregnancy in Ethiopia; further analysis of the 2016 Ethiopian demographic health survey data

BACKGROUND: Unintended pregnancy an important public health problem in Ethiopia. It is associated with adverse physical, mental, social and economic outcomes. Identifying factors associated with unintended pregnancy may help to reduce unintended pregnancy and hence adverse outcomes. There are few studies about the prevalence and associated factors of unintended pregnancy in Ethiopia. But these studies were based on small sample size and fragmented. Therefore, this analysis was done to identify factors associated with unintended pregnancy in Ethiopia based on nationally representative data. METHODS: The study used the 2016 Ethiopian demographic and health survey data. The data was downloaded from The DHS program with permission. A total of 1135 women were included in the final model. Data was weighted to consider disproportionate sampling and non-response. Multivariable logistic regression was used to identify factors associated with unintended pregnancy among women. RESULT: About 30% (95% CI: 25.33–34.39) pregnancies were unintended. Married women (Adjusted odds ratio (AOR); 0.34; 95% CI: (0.01–0.14), woman living in developing regions AOR; 0.14; 95% CI: (0.07–0.27) and women who reported distance was not a big problem to get medical care AOR; 0.59; 95% CI: (0.36–0.99) had lower odds of unintended pregnancy. On the other hand, multiparous AOR; 3.77; 95% CI: (1.71–8.33), grand multiparous AOR; 6.72; 95% CI: (2.74–16.49) women and women who ever used contraceptives AOR; 1.86 95% CI: (1.06–3.26) had higher odds of unintended pregnancy. CONCLUSION: Although high, the magnitude of unintended pregnancy in Ethiopia was lower compared to the global level. Marital status, region, perceived distance to seek medical care, parity and history of contraceptive use were found significant predictors of unintended pregnancy in Ethiopia.
