Association Between Maternal High-risk Fertility Behavior and Pregnancy Intention Among Women Aged 15 to 49 in Rwanda: Analysis of the 2014-15 Rwanda Demographic and Health Survey

Abstract

Background: Maternal high-risk fertility behaviors have been linked to negative maternal and child health outcomes that include anaemia, undernutrition, and child mortality. In this context, we examined the association between maternal high-risk fertility behavior and pregnancy intention among women of reproductive age in Rwanda.Methods: This cross-sectional study is based on secondary data from the 2014–15 Rwanda Demographic and Health Survey (n=5661). The outcome of interest was pregnancy intention of the last child defined as intended or unintended. Maternal high-risk fertility behaviors were measured using maternal age at delivery, birth order, and birth interval. Chi-square test and multivariable regression models were performed. Results: The prevalence of unintended pregnancy was 46.8% (n=2652). Overall, 35.8% (n=2017) of women experienced single high-risk fertility behavior, while 23.1% (n=1282) of women experienced multiple high-risk fertility behaviors. Compared to women who have not experienced high-risk fertility behavior, the multivariable odds ratio (95% CI) of unintended pregnancy among women in single-risk and multiple-risk fertility behaviors were 2.00 (1.75, 2.28; p <0.001) and 2.49 (2.09, 2.95; p <0. 001.), respectively.Conclusion: Exposure to high-risk fertility behaviors is positively associated with unintended pregnancy among women in Rwanda. Therefore, reproductive and sexual health services should pay special attention to women who are <18 years or >34 years old; who have more than three children already; or have children with less than 24 months’ interval between giving birth.
