Objective: The aim of this study is to investigate the relationship between country level egalitarian values (broadly speaking emancipatory values/structural gender equality) and sexual behavior among youth. Methods: Comparative individual level data on sexual activity and condom use were collected from the Global School-based Student Health Survey, resulting in a final sample of 23 countries, analyzed utilizing multilevel logistic regression analysis. Results: Egalitarian values were significantly associated with sexual activity and condom use. Conclusions: Egalitarian values have a relationship with adolescents' sexual activity and condom use, and thus contribute to sexual health and well-being in Africa, South America and Asia.
