ABSTRACT
<p><b>OBJECTIVE</b>To analyze the characteristics of risky behaviors among different age groups of HIV positive female sex workers, and to explore the strengthening of their management.</p><p><b>METHODS</b>From January to June 2014, 22 814 female sex workers were investigated and tested HIV in 117 sentinel surveillance sites in Yunnan Province, and 181 were confirmed to be HIV antibody positive, who accepted questionnaire surveys. According to the age, the participants were divided into the < 35 years old age group and ≥ 35 years old age group. The demographic characteristics, knowledge about HIV/AIDS and related risk behaviors characteristics of the two groups were obtained via questionnaire surveys among 181 HIV positive female sex workers, and in-depth qualitative interviews were conducted from among 12 HIV positive sex workers.</p><p><b>RESULTS</b>HIV antibody positive rate was 0.8% (181), the age of the 181 subjects were (35.83 ± 9.17) years old, 76 cases (42.0%) were < 35 years old, and 105 cases (58.0%) were ≥ 35 years old. The differences of marital status, workplace class, the last work site among two groups were statistically significant (χ(2) = 20.80, 28.32, 7.83; P < 0.001, P < 0.001, P = 0.020, respectively). Among 181 HIV, the proportion of AIDS awareness was 95.6% (173); the proportion of drug use among ≥ 35 years old age group was 51.4% (54), which was higher than that in < 35 years old age group (34.2%, 26/76) (χ(2) = 5.30, P = 0.021). 96.7% (175) received condom promotion or HIV counseling and testing in the past year. The proportion of continuing to engage in sexual services over 5 years after HIV infection was 48.5% (51/105) and the proportion of receiving antiretroviral treatment was 69.5% (73/105) in ≥ 35 years old age group, which were higher than those in the < 35 age group (30.2% (23/76), 52.6% (40/76); χ(2) = 12.26, 5.36; P = 0.002, 0.021, respectively). In-depth interviews among 12 HIV positive female sex workers found that regular clients, not consistent use of condoms were the main cause of no condom use. Economic and livelihood factors are important reasons for continuing to engage in sexual services among HIV positive sex workers.</p><p><b>CONCLUSION</b>HIV positive sex workers still have high risk behaviors including continuing to engage in commercial sexual service and no condom use after knowing their HIV infection status, and the proportion of using drugs in the ≥ 35 years old group was higher than that in < 35 years old group.</p>
