VACS=Violence Against Children and Youth Surveys.

*

The adjusted model for females controlled for age, educational attainment, marital status, orphan status, rural versus urban status, and previous pregnancy using logistic regression; the adjusted model for males controlled for age, educational attainment, marital status, orphan status, and rural versus urban status using logistic regression; the logistic regression was used to assess if changes in the prevalence were significant after controlling for the important covariates; for child marriage, the adjusted model for both females and males excluded marital status because of the high correlation between marital status and early child marriage.

β coefficients were generated using logistic regression, accounting for the complex survey design of the Kenya VACS.

n includes only those who had sex in the previous 12 months.

§

Transactional sex includes exchanging sex for money, food, gifts, or other favours.

n includes only those who have ever had sex.

n includes every survey participant.

**

Includes disease acquired through sexual contact, or bad-smelling abnormal genital discharge, or a genital sore or ulcer.
