This study examined the attitudes, knowledge, and sources of informati
on of 81 Mexican adolescents. Findings indicated that 85% of the adole
scents had received some sex education in school, but only 8% believed
that teachers should be responsible for sex education. The majority w
ere satisfied with what they knew about sex. However on a series of 9
knowledge questions, the greatest mean score was 5.5. Finally, informa
tion elicited regarding attitudes was generally conservative, with mos
t respondents indicating that people (especially females) should be ma
rried before they have sex and that sex without love is not okay. This
article contributes to the limited literature on Mexican adolescent s
exuality in an effort to increase the ability of health education prov
iders to plan programs for this population, both in Mexico and in the
United States.
