title: Age of sexual initiation and HIV-related behaviours: application of survival analysis.
abstract: Previous studies have consistently suggested positive associations between early sexual initiation and subsequent risky sexual behaviours, HIV/STD infection, adolescent pregnancy and substance use. In the present study, survival curves for rural-to-urban migrants in China with and without HIV-related behaviours were analysed to determine (1) the risk of initiating sex at each ageand (2) the association between sexual initiation and HIV-related behaviours.
