Transition into first sex among adolescents in slum and non-slum communities in Nairobi, Kenya
Open accessAbstract
While early sexual experiences are a key marker of the transition from childhood to adulthood, it is widely acknowledged that precocious initiation of sexual activity predisposes adolescents to negative health and psychological outcomes. Extant studies investigating adolescent sexuality in sub-Saharan Africa often rely on cross-sectional data lacking information on the social-psychological underpinnings of adolescent behavior. Through the theoretical lens of the protection-risk conceptual framework, this paper draws on two waves of longitudinal data collected from 2,134 adolescents to examine sociodemographic, psychosocial and behavioral predictors of transition to first sex among adolescents living in slum and non-slum settlements in urban Kenya. We employ logistic regression models to examine the effect of antecedent sociodemographic and risk and protective factors measured during the first wave of data collection on transition to first sex by the second wave. We observe that transition to first sex is influenced by age, slum residence, perceived parental monitoring, and peer behavior. We also find evidence for coupling of risk behaviors. Study findings underscore the need to focus on very young adolescents and those growing up in resource poor settings as these young people may be highly vulnerable to negative health outcomes stemming from precocious sexual activity.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
