Survey on epidemiology and habits of seeking medical services of 109 patients with sexual transmitted diseases (STDs) (62 male and 4 female) at National Dematology Hospital shows that prevalence is higher among youth (20-39); state workers 33.9%; mostly in urban areas (68.8%); people had high school education and more (77.4%). Most women had married (60.9%); while most men have been single (89.2%). Male patients often contracted STDs due to having sexual activities with partners or sex workers (81.6%). Female patient contracted STDs mainly through husband (85%). Most STD patients seek for medical service within the next days (77.9%) or months. Those who came to hospitals/dermatology institute/dermatology centre was 53.2% and those who came to private clinics and chemistry for self treatment is 31.1%.
Sexually Transmitted Diseases, Epidemiology, Habits

OBJECTIVETo understand the change trend of the awareness rate of HIV/AIDS related knowledge, risk behaviors among men who have sex with men (MSM) in Yunnan and the factors influencing their condom use, and evaluate the effect of comprehensive intervention.

METHODSThe data about the MSM's demographic information, HIV/AIDS related knowledge awareness, and sex behavior, condom use, drug use and intervention receiving were obtained from AIDS sentinel surveillance among MSM in Yunnan province during 2010-2013 to conduct change trend and influencing factor analysis.

RESULTSA total of 9 073 MSM were surveyed. The awareness rate of the HIV/AIDS related knowledge, homosexual behavior and condom use rate increased year by year (P < 0.01). The condom use rate was lower in heterosexual behavior, and the drug use rate and sexually transmitted disease prevalence declined with year (P < 0.01). Multivariate logistic regression analysis indicated that cohabiting, low awareness of HIV/AIDS related knowledge, being from other provinces, local residence for <1 year, low education level, receiving no intervention, frequent anal sex and receiving no HIV/AIDS detection were the risk factors influencing persistent condom use among MSM.

CONCLUSIONThe effect of HIV/AIDS comprehensive intervention was observed after 4 years implantation, but most of the index were at low level. More attention should be paid to the intervention among MSM with cohabiting habit, low education level, frequent anal sex, and heterosexual sex. It is necessary to expand intervention coverage, strengthen HIV test and promote condom use among MSM.
