Multivariable logistic regression was used to analyze the effect of health service utilization on the occurrence of high risk sexual behavior and HIV infection.Results Of 142 participants, 85.2% (121/142) knew the free HIV VCT service and 76.0% (92/142) knew the place to take the free testing. The overall awareness rate of AIDS was 87.3% (124/142); 57.7% of them wanted to know how to prevent AIDS. The overall coverage of service programs was 100.0 %, the coverage of internet propaganda was 80.3% (114/142), and VCT service coverage was 57.7 % (82/142).
