2018 denominator: AGYW followed up in 2018 (Overall totals: Gem 1171; Nairobi 836; uMkhanyakude 1853).
2019 denominator: AGYW followed up in 2019 (Overall totals: Gem 1018; Nairobi 852; uMkhanyakude 1712).
Method: Propensity-score regression adjustment.
Outcome definition social support: Binary outcome variable constructed where a high level of social support was defined as a ‘yes’ response to at least three out of four questions: ‘Is there a female in your community from whom you can borrow money in an emergency?’; ‘Do you have at least one trusted female friend?’; ‘Do you know a woman in your community, other than a mother or guardian, whom you could turn to if you had a serious problem?’; ‘Do you have a safe and private place to meet with girls and young women who are like you?’Outcome definition self-efficacy: Binary outcome variable constructed based on a series of ten questions comprising a general self-efficacy scale, where a cut-off value of ≥3.5 was used to define higher self-efficacy (yes).
AGYW, adolescent girls and young women; DREAMS, Determined, Resilient, Empowered, AIDS-free, Mentored and Safe.
