Patterns of Sexual Behaviors among Unmarried Adolescents and Youth in Three Asian Cities

We examined patterns of sexual behaviors of unmarried adolescents and youth (UAY) in three Asian cities (Shanghai, Taipei, and Hanoi) and identified factors related to the timing of initial sexual experience. From analysis of a sample of 16,554 UAY aged 15-24 years recruited from Shanghai, Taipei, and Hanoi plus data collected from face-to-face interviews complemented by computer-assisted self-interviews for intimate questions, we learned: UAY in Shanghai, Taipei, and Hanoi have different sexual behaviors. Affluent economic status increases the likelihood of early initial sexual experiences. Higher educational attainment may delay initial intercourse. Compared with Shanghai UAY, study participants from Taipei and Hanoi were 3.64 times and 0.33 times as likely to participate intercourse. These data can provide a basis for developing effective government policies and social interventions.
