title: [Association between HIV infection and female sex workers in middle aged and old men in a city in Hubei provine, 2014].
abstract: OBJECTIVE
  To understand the HIV infection status in middle aged and old men and the association between HIV infection and female sex workers in a city in Hubei province and provide evidence for the targeted prevention and control of HIV infection.
  
  
  METHODS
  Ten communities/villages were selected through stratified cluster sampling from the suburban and rural areas of the city. A total of 634 men aged ≥50 years were surveyed by using self-designed questionnaire in December, 2014.
  
  
  RESULTS
  The awareness rate of HIV/AIDS related knowledge was 13.3%(68/513). Among the men surveyed, 63.2%(371/587)thought they couldn't be infected with HIV, 9.1%(52/573)believed that extramarital sex is acceptable, and 32.4%(189/583)considered that commercial sexual behavior is just as well. Among the surveyed men reporting sexual behavior in the past 6 months, 6.6%(15/228)had sex with regular sexual partners, in which 63.6%(7/11)never used condoms, 21.8%(128/586)reported that some friends had commercial sexual behaviors. Among 601 men receiving HIV testing, 7 were HIV positive(1.2%). The HIV detection rates among the men living at 3 communities near red light district were 4.2%(5/119), 1.1%(1/95)and 0.5%(1/192)respectively; while no HIV infections were found in the men living at 2 towns far away from red light district. Seventy seven of 581 men surveyed(13.2%)reported to meet visiting female sex workers and they had higher HIV positive rate(5.2%, 4/77)than those without such experiences(0.6%, 3/504)(P=0.007).
  
  
  CONCLUSIONS
  The middle aged and old men in this city had low awareness of HIV/AIDs related knowledge, and high-risk sexual behaviors existed among them. HIV positive rate was relatively high in this population, and HIV infection might be associated with sex service.
