Sexually transmitted infection risk behaviors in rural Thai adolescents and young adults: support for sex- and age-specific interventions.

Sexually transmitted infection (STI) prevalence and risks in a sample of rural Thai adolescents and young adults (14-29 years) were examined. Unprotected sex with a casual partner conferred the greatest risk for prevalent STIs particularly for younger adolescents and alcohol use increased the STI risk for women but not for men.
