Abstract:
Abstract: Objective To understand the behavioral characteristics of men who have sex with men (MSM) in different sexual roles and the current status of syphilis-HIV co-infection and mono-infection in Shenzhen, and to analyze the relationship between sexual roles and syphilis-HIV status. Methods The snowball and respondent-driven sampling (RDS) were used to recruit MSM in Shenzhen for questionnaire surveys and serological testing of syphilis and HIV. Chi-square test, Wilcoxon two-sample test, Kruskal-Wallis test, and multivariate logistic regression model were used to analyze the factors associated with the sexual roles and syphilis-HIV co-infection and mono-infection. Results A total of 839 MSM were recruited from 2019 to 2021. Of all, 289(34.45%) were receptive group, 270(32.18%) were insertive group, and 280(33.37%) were versatile group. Statistically significant differences were found among the three groups in age, household registration, educational background, first sexual partner, age of having anal sex for the first time, number of sexual partners in the last 6 months, having heterosexual sex in the last 6 months, and drug abuse (rush) in the last 6 months (χ2=34.980, 9.570, 7.621, 7.924, 23.229, 11.991, 37.717, 10.678, P<0.05). Among 839 MSM, the prevalence of syphilis-HIV co-infection, mono-HIV infection, and mono-syphilis infection were 4.17%, 5.13%, and 9.54%, respectively; the infection rates of the receptive group were 5.54%, 6.92%, and 10.03%, respectively; the infection rates of the versatile group were 4.29%, 6.43%, and 9.64%, respectively; the infection rates of insertive group were 2.59%, 1.85%, and 8.89%, respectively; there were statistical differences in infection rates of syphilis-HIV co-infection and mono-infection among different sexual roles (χ2=14.520, P=0.024 3). Ordinal logistic regression indicated that playing exclusively receptive and versatile roles in anal sexual intercourse in the last 6 months, the older MSM (≥30), senior high school and below, the younger age at the first anal, having 6 or more anal sexual partners, and not insist on using condoms in anal sexual intercourse were associated risk factors for syphilis-HIV co-infection and mono-infection. Compared with MSM in the insertive group, receptive MSM had 2.21 times the risk of syphilis-HIV co-infection and mono-infection (aOR=2.21, 95%CI:1.39-3.51), and versatile MSM had 1.26 times the risk (aOR=1.26, 95%CI:1.07-2.18). Conclusion MSM with different sexual roles exhibit distinct demographic and sexual behavior characteristics, as well as varying risks for syphilis and HIV infections. Individualized and different corresponding preventive measures should be taken for MSM towards different sex roles and sexual behaviors.
