PMA Agile, a project within PMA2020, sought a means of measuring contraceptive awareness and use among adolescents and youth as they enter a period of probable sexual activity. PMA Agile typically monitors contraception uptake via clinic-based surveys of providers and clients; however, in this age group, it is suspected that youth and adolescents may be procuring contraceptives via other means, making young contraceptors effectively “hidden” to clinic staff and compromising the accuracy of clinic-based survey measures. Capturing information from youth clients of health facilities, especially unmarried females, is challenging due to social and familial pressure to hide sexual activity and contraceptive use. It is within this context that PMA Agile in collaboration with the International Centre for Reproductive Health-Kenya (ICRHK) conducted a survey of youth aged 15-24 years in Nairobi using respondent-driven sampling (RDS) methodology. This study is a companion study to the pilot YRDSS that was conducted in Abidjan, Côte d’Ivoire in 2018 (AIBEF & PMA Agile, 2019).
