TABLE 2: Summary of risky sexual practices among sexually active adolescents and young adults by gender.

Sexual debut before age 15 years (n = 2311) 119 15 129 9 0.59 0.41–0.85 0.01

Transactional sex (n = 2048) 18 2 122 8 3.46 2.07–5.77 < 0.0001
Note: A PR of > 1 indicates that the ratio of females reporting a specific sexual practice exceeds that of males. For example, self-reported inconsistent condom use was 61% more prevalent among
females than males, whereas a PR of < 1 indicates that fewer females reported the practices compared to males.
CI, confidence interval; PR, prevalence ratio.
