Factors affecting birth interval among mothers in Dabat district, Amhara Regional state, Northwest Ethiopia: A community-based cross-sectional study, 2022

INTRODUCTION: Birth interval is the time period from live birth to a successive pregnancy or successive live birth which is the recommended to be at least 2 years or at least 33 months respectively. Both short and long birth intervals are associated with poor health outcomes for both mothers and babies. Therefore, the main objective of this study is to assess the length of birth intervals and its predictors among reproductive-age women in Dabat district. Methods: community-based cross-sectional survey conducted from December 10/2020 to January 10/2021. This study was done on 1262 multi para women. Five days training was given for the data collectors and supervisors. Bivariable and multivariable ordinal logistic regression analysis were done. Those variables which had P-value less than 0.25 in the bi variable analysis were entered to multivariable ordinal logistic regression analysis. An adjusted odds ratio with a 95% confidence interval and P-value less than 0.05 was used to determine significant determinants of birth interval. RESULT: This study revealed that the magnitude of short and long birth interval was 30.59% and 22.82% respectively. Wealth status (poor: AOR = 0.72, CI: 0.53, 0.97), maternal education (Diploma and above: AOR = 2.79, CI: 1.18, 6.56), ANC follow up (having ante natal care: AOR = 2.15, CI: 1.72, 2.69), husband occupation (Employed: AOR = 1.77, CI: 1.03, 3.01) and history of abortion (abortion: AOR = 2.48, CI: 1.08, 5.66) were statistically significant factors. CONCLUSION: Higher percentage of mothers have either short or long birth interval. Birth interval is affected by socio demographic characteristics of mothers and husbands.
