Reducing HIV Risk Among Mexican Youth

Sexually transmitted HIV infection among adolescents is a growing and significant problem in
Mexico. Given the high mortality rate associated with AIDS, the lack of available
treatment, and the social stigma associated with the disease, prevention is the key to
reducing the threat of AIDS among this important subgroup in Mexico. The study has four
specific aims including 1) to determine whether the HIV risk-reduction intervention causes a
greater increase in adolescents' intentions to abstain from intercourse and/or avoid
unprotected intercourse at post-intervention and decreased self-reported intercourse and
unprotected intercourse at 3, 6, 12, and 48 month follow-ups, compared with the general
health promotion control intervention; 2) to determine whether the effects of the
intervention are moderated by individual, microsystem, and macrosystem variables; 3) to
identify theory-based variables that mediate effects of the HIV intervention on adolescents'
self-reported behavior; and 4) to determine whether the HIV risk-reduction intervention
causes a greater increase in parents' comfort with, and quantity of communication (general
and HIV specific) with adolescents at post-intervention, 3, 6, 12, and 48 month follow-up
compared with the general health promotion control intervention.
