The standardized gender-role conformity score is considered a continuous variable in all analyses. All models are adjusted for age, region, ethnicity, school type, average monthly expenditure, self-rated parent–child relationship, if he or she has ever received sexual education at school, if he or she has had parent–child discussions relevant to sexual behaviors, parents’ highest educational attainments, tobacco consumption, and alcohol consumption. ACME = average causal mediation effect, ADE, average direct effect; PM, proportion of mediation.

^aAnalyze for individuals who have never had sexual intercourse. n = 10,613 for males, and n = 23,130 for females.
