Purpose: Migrants are identified as a high-risk group for HIV and STIs in China. The purpose of this study is to determine age of sexual debut across migrant and non-migrant groups in Shanghai, China. Methods: Survival analysis methods were employed on a cross-sectional survey of 6,299 15-24 year olds. Kaplan-Meier estimates as well as Cox proportional hazards models with time-varying effects were used to assess the effects of time-interaction of age of sexual debut with migration status. Results: Overall, only 15% of the study population experienced premarital sex, with differences across migration status (p<0.05). Age of sexual debut differed across men and women. For women, rural non-migrants were at greater risk of earlier sexual debut (HR=1.92, CI: 1.34-2.74), and rural-to-urban migrants were at greater risk of sexual debut compared to urban non-migrants (HR=1.79, CI: 1.07-2.99). Conclusions: Results indicate that prevention efforts should target rural non-migrants and rural-to-urban migrant women.
