Individual, Partner, and Community Variables Associated With Method-Specific Contraceptive Beliefs in Urban and Rural Kenya

Abstract

Global unmet need for contraception remains high. Contraceptive health-related beliefs are a barrier to contraceptive use but are poorly understood. This study examined quantitative differences in two health-related beliefs between pills, injectables, and implants.

Study design: We used cross-sectional baseline data collected between August and December 2016 from Nairobi (urban) and Homa Bay (rural) Kenya among women aged 15 to 39 years (N = 5081). Dichotomous outcome variables were constructed for two health-related beliefs (infertility and serious health problems) for the three methods. Using a socioecological framework, possible risk factors at individual, relationship, and community levels were identified a priori. We used logistic regression to identify factors associated with method-specific beliefs.

Results: Roughly a quarter of participants believed the methods caused serious health problems, while a smaller overall proportion believed the methods caused infertility. Risk factors patterned similarly across methods but differed between beliefs. In adjusted models, perceived partner approval of a method was associated with lower odds of believing it caused infertility or serious health problems. Unsatisfactory or mixed social network experiences predicted serious health problems but not infertility beliefs. Current use was associated with lower odds of believing all three methods caused serious health problems, but only implant users were more likely to believe they caused infertility. Past use was associated with higher odds of serious health problems but not infertility beliefs.
