Abstract
A birth interval is the length of time between two successive live births. World Health Organization is recommended that individuals and couples should wait for at least 2–3 years between births to reduce the risk of adverse maternal and child health outcomes. Short birth interval also has a negative consequence on perinatal, neonatal, and child health outcomes. This study aimed to assess the level and determinants of the short birth interval among reproductive-age women in Ethiopia. National population-based cross-sectional study design was employed. The total weighted sample included in the analysis was 6,155 women who have given birth five years preceding the survey. Multilevel Logistic regression models (bivariate and multivariate) were used to assess the association between dependent and independent variables. In multiple multilevel logistic regressions those variables' P-value <0.05 was considered as a statistically significant variable for short birth interval and presented with 95% CI and AOR. The prevalence of short birth interval was 48.5%, [95% CI, 47.18- 49.69]. The predictors associated with short birth intervals like rural residence [AOR=1.4, 95% CI: 1.1,1.7], women's being Muslim religion (AOR=2.3, 95% CI: 1.9-2.7), women whose age at first birth from 18 to 34 years [AOR=1.2, 95% CI:1.1, 1.4, p<0.001] were found to be statistically significant determinants of short birth interval. Half of the women have reported the short birth interval experience in Ethiopia. The main factors for short birth intervals were women who lived in rural settings, women being religious, and women age at first marriage. These factors addressed through the maternal and child health program should intensify their program on influencing mothers by giving information about the necessity of using modern contraceptives in spacing children.
