^aParticipants who reported a sexual debut at or before age 13 were considered to have had early sexual debut. Seventeen participants were excluded because age of debut was <10 years old

^bThe sexual risk composite variable indicates participants who reported engagement in sexual intercourse and one or more of the following: sexual debut at or before 13 years old, multiple sexual partners, and not having used a condom at last sexual intercourse

^cAll explanatory variables that correlated with the dependent variable with a p <0.20 were included in the full model. A backwards elimination strategy was used to generate the adjusted model. All explanatory variables in the adjusted model associated with the dependent variable with p < 0.05

^d95 % confidence intervals

^eAge was treated as a continuous variable. OR represents the increase in odds with each year of age

^fEducation was treated as an ordinal variable. OR represents increase in odds with each of five categories (1st grade or less, 1st–6th, 7th–9th, 3rd–4th secondary school and graduated)

^gFamily structure indicates with whom participants lived
