Prevalence and determinants of contraception utilization over time in Migori County, Kenya: Repeated cross-sectional household surveys

Abstract

Contraception use and family planning have been shown to save lives and benefit women, their families, and their communities. We  conducted a cross-sectional study analyzing data from a 2021 survey that was conducted across eight different regions in Migori  County,  Kenya to examine the potential role that different factors play in meeting family planning targets. Comparisons are made  to data  collected in 2018/2019 in order to estimate the change over time of contraception uptake. Descriptive statistics were  calculated, the  Cochran–Mantel–Haenszel test was used to compare contraception use over time, and multivariable logistic  regression was used to  model determinants of contraceptive use. Sixty-four percent of respondents in 2021 reported that they  currently use some form of  contraception, and implants are the most popular contraceptive method. Factors associated with higher  contraception usage were  region, ages 25-34 years, and marital status. Contraception uptake increased significantly in East  Kamagambo following a community- driven sexual and reproductive health intervention by the Lwala Community Alliance,  suggesting that increased investment in family  planning may be influential. We recommend targeted outreach to population groups  with low uptake of contraception and investment in  both demand- and supply-side interventions to increase contraceptive uptake.  Additional research, especially for populations under  18, is needed to further inform effective investment and policy.
