Face-to-face questionnaires survey and HIV antibody test were conducted. Results A total of 408 people were surveyed, including 313 males and 95 females aged 50-88 （64.93±9.03） years. The HIV infection rate was 1.47% （6/408）, with the rate of 1.28% （4/313） in males and 2.11% （2/95） in females. The awareness rate of AIDS related knowledge was 37.50% （153/408）.

The results of multivariate logistics model analysis on extramarital sexual behaviors showed that the prevalence in males were 39.51 times higher than that in females （OR=39.51, 95% CI：5.03-310.30）, 4.60 times higher in those who were unmarried, divorced or widowed than that in the married or cohabitants （OR=4.60, 95% CI：1.50-14.05）, 2.03 times higher in those with outside activities than those with individual activities （OR=2.03, 95% CI：1.08-3.81） and 3.94 times higher in those with self-evaluation of emptiness of living state than that in those with engaged life （OR=3.94, 95% CI：1.86-8.36）.
