Using prevention cascades to investigate coverage of contraception services among young women enrolled in a large-scale combination HIV prevention program in South Africa.

ABSTRACT

OBJECTIVES: We investigated the coverage of contraception services (excluding condoms) to prevent unintended pregnancy among young women and girls aged 15 to 24 years who were beneficiaries of one of the two largest combination HIV and pregnancy prevention program in South Africa. STUDY DESIGN: We invited 2160 randomly sampled beneficiaries who were living in six of the 12 program districts across six provinces to participate in a telephone survey. We created pregnancy prevention coverage cascades and conducted univariate and multivariable analyses to identify key barriers and facilitators associated with each step of the cascade. RESULTS: We achieved a response rate of 23.8%, resulting in 515 respondents, of whom 303 had sex in the 6 months before the survey. Of this subsample, 80.4% had access to contraception services, 60.6% had access and motivation to use contraceptives, and 21.9% had access to, motivation to use, and effectively used contraceptives. Distance to travel to services and not ever being offered contraceptives by health workers were access barriers, while low pregnancy risk perception was a barrier to motivation. CONCLUSIONS: Most respondents had access to and were motivated to use contraceptives other than condoms but were not effectively using them. Having been offered contraceptives facilitated better access, while distance to the services was a barrier, suggesting the importance of improving supply-side interventions, such as increasing the number and accessibility of spaces where Sexual and Reproductive Health (SRH) services are offered. We recommend longitudinal behavioral counseling for young people, especially adolescents, as well as risk reduction and information-tailored interventions. IMPLICATIONS Pregnancy prevention cascades are a promising tool to monitor progress toward universal access to contraception services and to identify barriers that need to be addressed to achieve the effective use of contraceptives.
