Methods: Data for this article were drawn from the international cross-sectional survey on sexual and reproductive health of adolescents and young adults aged 15-24 years in three Asian cities (Hanoi,Shanghai,and Taipei), conducted in 2006 . The original sample consisted of a representative group of 17,016 adolescents; while in this study ,16,554 never-married adolescents were included in the analysis. Both face-to-face interview and computer-assisted self-interview approaches were adopted in the survey. Exposure to family concepts, self-cultivation values, gender role concepts, and sexual values were the main measures of traditional Confucian cultural influence. Sexual and intimate behaviors were the main outcome measures, and multi-Cox regression models were used to assess the association between traditional cultural concepts and values and sexual behavior after adjusting for potentially confounding factors. Data were analyzed with SAS software 9.1.
