Objective:To explore the correlation between alcohol drinking and high-risk sexual behaviors in HIV negative clients of female sex workers and provide scientific evidence for prevention of HIV sexual transmission.Methods:A cross-sectional survey was conducted in HIV negative clients in Ji’nan and Haikou from December 2018 to May 2019. The estimated sample size was 337, the information about their demographic characteristics, AIDS knowledge awareness, sexual behaviors and alcohol drinking habit were collected through convenience sampling. The data were analyzed by using SPSS 24.0 software.Results:A total of 381 clients were included in this study. Most of them were less than 40 years old, accounting for 89.2% (340/381); 85.3% of them (325/381) reported an education level of high school and above; the clients who were married, had cohabitation with females or had girl friends accounted for 53.2% (202/380). The overall awareness rate of AIDS knowledge was 83.7% (318/380). Of all participants, 80.8% (308/381) had commercial sex in the past year, 79.8% (304/381) had non-commercial sex partners, 62.7% (239/381) had high-risk sexual behaviors. The results of logistic regression showed that compared with those with alcohol drinking frequency ≤2 times per month in last year, the clients with alcohol drinking frequency more than once a week (a OR=3.22, 95 %CI: 1.25-8.27) were more likely to have high risk sexual behaviors after adjustment for age, living area, location type of residence, time of local residence, education level, monthly income level, occupation, marital status, knowledge awareness of AIDS and HIV related services, the number of commercial or non-commercial sexual partners in the past year, cost of commercial sex and HIV test frequency. Conclusions:Alcohol drinking is related to high risk sexual behaviors in HIV negative clients, and will increase the risk of HIV transmission. To control AIDS, the intervention of alcohol drinking should be combined with other preventions to improve the correct use of condoms.

Objectives:To investigate the potential classification of quality of life in HIV-infected men who have sex with men (HIV-infected MSM) and to analyze possible influencing factors of different categories.Methods:A questionnaire survey was conducted among HIV-infected MSM who received antiretroviral treatment (ART) in an infectious disease hospital in Ji'nan, Shandong Province from October to December 2020. The quality of life scores in six domains were analyzed by latent profile analysis (LPA), and possible related factors of potential classification were explored by ordinal logistic regression analysis.Results:A total of 584 HIV-infected MSM were included in this study. LPA divided their quality of life into three categories, named low score, medium score and high score groups, accounting for 34.4% (201/584), 49.8% (291/584), and 15.8% (92/584), respectively. Multivariate ordinal logistic regression analysis showed that age above 40 years (a OR=1.77, 95% CI:1.11-2.80), monthly average income of 3 000 Yuan and below (a OR=3.15, 95% CI:1.72-5.76), monthly average income of 3 001-5 000 Yuan (a OR=2.26, 95% CI:1.41-3.62), distance to the hospital to receive drugs farer than 40 kms (a OR=1.76, 95% CI:1.07-2.89), and adverse reactions after taking drugs (a OR=2.31, 95% CI:1.65-3.23) were factors associated with low level of quality of life. Conclusions:The qualities of life of HIV-infected MSM showed group heterogeneity and were at high levels. Attention should be focused on HIV-infected MSM who are at older age, with low income, and long distance to access the health facilities. The measures should be taken to reduce the adverse reactions of ART drugs and improve the quality of life.
