Adolescents, particularly those aged 14 to 15y, often begin exploring their sexuality, during which time they are more vulnerable to traditional influences and ideologies imposed by society. This study aimed to identify the association between more traditional attitudes toward women and sexual risk attitudes and behaviors in Peruvian adolescents. Cross-sectional study with data from the fifth round of the Young Lives study with 1860 adolescents aged 14 and 15y. Population characteristics were described by relative frequencies and using chi-squared test with p-value. The 12 items of the Attitudes toward Women Scale for Adolescents instrument were analyzed by relative frequencies and mean with standard deviation. For further analysis, the values of the global scores of all participants were divided into two categories, using the median as the cutoff point, where the group with higher scores indicated that these adolescents had more traditional attitudes (or more gender stereotypes). More traditional attitudes were associated with sexual risk attitudes and behaviors, with crude prevalence ratio (PR) and then adjusted prevalence ratio (aPR) with 95% CI. The Universidad Privada de Tacna's ethics committee approved the research protocol. Adolescents with more traditional attitudes were more likely to have sexual risk attitudes compared to those with less traditional attitudes. In addition, adolescents with more traditional attitudes were 2.6 times more likely to have at least one sexual intercourse while drunk as compared to the reference group (95% CI: 1.43-4.74; p=0.002). The expression of more traditional attitudes toward women was associated with sexual risk attitudes. However, there was no association with most of the sexual risk behaviors studied, except for the higher probability of having at least one sexual intercourse while drunk.
