title: Unmarried male migrants and sexual risk behavior: a cross-sectional study in Shanghai, China.
abstract: BACKGROUND
  In China, there is increasing concern because of the rapid increase in HIV infection recorded over recent years. Migrant workers are recognized as one of the groups most affected. In this study, HIV/AIDS-related knowledge, attitudes, and behavior among unmarried migrant workers in Shanghai are investigated, with the aim of providing critical information for policy makers and sex educators to reinforce sexual health services and sex health education targeting the behavior and sexual health of unmarried male migrants.
  
  
  METHODS
  A cross-sectional survey was conducted among unmarried male migrant workers in Shanghai, China's largest city and housing the most migrants. A self-administered, anonymous questionnaire was used to collect information on knowledge, attitudes, and behavior associated with increased risk of HIV/AIDS.
  
  
  RESULTS
  A total of 2254 subjects were questioned, with a response rate of 91.3%. Among those interviewed, 63.5% reported sexual activities. Misconceptions regarding HIV transmission, poor perception of HIV infection, and low use of condoms were not uncommon. Among those who had sexual intercourse, 73.7% had not used condoms in their last sexual intercourse, and 28.6% reported having engaged in sexual risk behavior (defined as having at least one non-regular partner). Multivariate logistic regression analyses identified several indicators of sexual risk behavior, including younger age at first sexual intercourse (OR: 0.67, 95% CI: 0.31-0.91 for older age at first sexual intercourse), more cities of migration (OR: 2.91, 95% CI: 2.17-3.81 for high level; OR: 1.15, 95% CI: 1.06-1.29 for medium level), poor perception of acquiring HIV/AIDS (OR: 1.52, 95% CI: 1.33-1.96 for unlikely; OR: 2.38, 95% CI: 1.61-3.70 for impossible), frequent exposure to pornography (OR: 0.33, 95% CI: 0.11-0.43 for never; OR: 0.69, 95% CI: 0.60-1.81 for less frequently), not knowing someone who had or had died of HIV/AIDS and related diseases (OR: 2.13, 95% CI: 1.70-2.53 for no), and having peers who engaged in sex with a non-regular sex partner (OR: 4.40, 95% CI: 3.37-5.56 for yes).
  
  
  CONCLUSIONS
  Today, it is necessary to reinforce sex health education among unmarried migrants and sexual health services should target vulnerable migrant young people.
