Factors associated with unsafe sex among Kenyan youth:

Abstract

BACKGROUND
 Understanding sexual risk among youth can inform the design of effective HIV prevention interventions.
 METHODS
 The 2012 Kenya AIDS Indicator Survey was a nationally representative population-based survey. We administered a questionnaire and collected blood samples for HIV testing. We examined factors associated with unsafe sex among unmarried youth aged 15-19 and 20-24 years.
 RESULTS
 Of 2,090 unmarried youth aged 15-19 years, 33.3% (95% confidence interval [CI] 30.6-36.1) had ever had sex. Among those, 66.0% (95% CI 61.3-70.7) had sex in the past year (sexually active), and of these, 38.7% (95% 33.4 – 44.0) reported unsafe sex. No differences were observed in unsafe sex by sex. Factors associated with increased adjusted odds of unsafe sex among youth aged 15-19 years were residence in Central province; having primary or lower education; sexual debut before age 15 years; ever receiving money, gifts or favours for sex (transactional sex); multiple sexual partners in the past year; and low self-perceived risk of HIV. Of the 1,079 unmarried youth aged 20-24 years, 77.2% (95% CI 74.2-80.2) had ever had sex. Of these, 73.1% (95% CI 69.8-76.3) were sexually active, and 24.1% (95% CI 18.1-30.1) of women and 31.9% (95% CI 26.4-37.5) of men reported unsafe sex in the past year. Factors associated with increased adjusted odds of unsafe sex among youth aged 20-24 years were primary or lower education, transactional sex and multiple partners in the past year.
 CONCLUSION
 Unsafe sex is common among Kenyan youth, especially those aged 15-19 years. HIV prevention efforts need to target youth, support educational progression and economic empowerment.
