Abstract
Introduction: Birth spacing is the time gaps between two consecutive life births. One of the key strategies to reduce fertility and promote the health status of mothers and their children is optimal birth spacing. Recent evidences showed that the health of mothers and children with the birth interval of 3 to 5 years is safer than 2 years or less. However, women still have shorter birth intervals and studies addressing their associated factors were scarce. Objectives: To assess prevalence of suboptimal birth spacing practice and its associated factors among women of reproductive age in West Badwacho district, Hadyia Zone, South Ethiopia, 2020.Method and materials: Community based cross sectional study was conducted from February to March, 2020. Multi stage sampling technique was used to select samples of 626 women. Structured and pretested interview based questionnaire was used to collect the data. Data was checked for completeness and entered using EPI data version 3.1 and analyzed using SPSS version 25. Bivariable logistic regression was done and variables with a p-value of < 0.25 in bi-variable logistic regression were recruited as candidate variable for the final multivariable logistic regression model and P value less than 0.05 at 95 % confidence level was taken as statistically significant. Result: The prevalence of suboptimal birth interval in this study was 60.4 %. Independent predictors of suboptimal birth spacing were: age at first marriage less than 18 years (AOR: 2.18, 95% CI=1.34,3.53), HEWs education about birth sapcing (AOR: 1.89, 95% CI=1.02,3.48), non -formal maternal education (A0R: 2.25, 95%CI=1.31,3.87), non -formal husband education (AOR: 2.64, 95%CI=1.74,4.01), sex of index child being female (AOR:1.58, 95%CI=1.06, 2.38),, having poor knowledge on optimal birth interval (AOR: 2.96, 95%CI=1.64,5.37), duration of breast feeding for less than 24 months (AOR: 4.64, 95%CI=2.32,9.29), and modern contraceptive non users (AOR: 6.31, 95%CI=3.99,9.96),Conclusion and recommendation: More than half of the study respondents were practicing suboptimal birth interval. Educational status, age at first marriage, HEWs education about birth sapacing, short duration of breastfeeding was some of the factors associated with the outcome variable. Thus, to optimize birth spacing, strategies of providing information using HEWs, education and communication targeting associated variables should be improved.
