Risky Sexual Behavior Among Mexican-Origin Emerging Adults in Los Angeles

This study examined the empirical link between substance use, and family, school, and contextual factors relevant to emerging adulthood and Mexican-origin emerging adults' sexual risk-taking behavior using a longitudinal design that followed the respondents from adolescence to emerging adulthood (n = 520). Overall, we found that engaging in one high-risk sexual behavior was associated with higher odds of engaging in another. While alcohol and substance use was associated with higher odds of engaging in risky sexual behavior, living with parents, having at least one parent who was a college graduate, sharing a higher level of parental closeness, being more bicultural, starting college, a new school, or classes, and feeling like an adult were associated with lower odds of engaging in sexual risk-taking behavior. Contrary to the study hypothesis, a higher level of family cohesion was associated with higher odds of such behavior. Lastly, male respondents tended to have more than 3 sexual partners but were less likely to not use condoms compared with their female counterparts.
