[Association between response to repeated negative HIV testing and risk sexual behaviors in men who have sex with men in Chengdu].

Objective: To investigate the association between the response to repeated negative HIV testing and the risk sexual behaviors in men who have sex with men (MSM) in Chengdu. Methods: A total of 610 MSM were recruited by convenience sampling method through Chengdu Tongle Health Consultation Service Centre from March to May 2022. Data were collected from the MSM through questionnaire survey, including the demographic characteristics, sexual behaviors in the past 6 months, the response to rerpeated negative HIV testing. Univariate and multivariate logistic regression models were conducted to analyze the association between the response to repeated negative HIV testing and risk sexual behavior. Results: A total of 579 (94.9%) participants participated in the questionnaire survey and 354 (61.1%) subjects were included in the study.For the negative HIV testing, some MSM believed that they had taken effective protection measures (17.03±2.20), some believed that they were lucky (7.50±1.87) and some believed that they were at low risk (8.87±3.62). Multivariate logistic regression model showed that protected sexual behavior was negatively associated with group sex (a OR =0.80, 95% CI : 0.67-0.95), lucky was positively associated with casual sex (a OR =1.20, 95% CI : 1.06-1.35), inconsistent condom use (a OR =1.21, 95% CI : 1.06-1.37), group sex (a OR =1.26, 95% CI : 1.00-1.60), and multiple sexual partners (a OR =1.24, 95% CI : 1.09-1.42) and low risk perception was positively associated with multiple sexual partners only (a OR =1.08, 95% CI : 1.01-1.15). Conclusions: There were high levels of recognition of protected sexual behavior and lucky dimensions in response to repeated negative HIV testing and well risk perception in MSM in Chengdu. In HIV testing and counseling services, intervention and risk warning should be strengthened in MSM who believed that they are lucky to improve their awareness of safe sex and reduce the negative effects of fluke mind.
