Abstract:
Objective:To analyze HIV testing behaviors and associated factors in men who have sex with men (MSM) and provide evidence for making intervention on promoting HIV testing.Methods:Our observational study was conducted between April and June, 2018 in Wuxi, Jiangsu province in MSM. A self-completed questionnaire was used to collect the information about their socio-demographic characteristics, sexual behaviors, acceptance of intervention services, psychological status and HIV testing behaviors. Structural equation model (SEM) was chosen to fit data and the model was modified to analyze the relationships between variables.Results:A total of 410 MSM were enrolled in our study, among whom 72.9%(299/410) were aware of the necessity of HIV testing and 69.0%(283/410) reported having HIV tests in the last year. A modified structural equation model presented good fitting results with fitting index of root mean square error of approximation (RMSEA)was 0.065, normed fit index (NFI) was 0.946, relative fit index (RFI) was 0.922, Tucker-Lewis index (TLI) was 0.968 and comparative fit index (CFI) was 0.952. Results of SEM showed that intervention service was the factor with the largest standardized total effect value of 0.57 associated with HIV testing behaviors among MSM. Among intervention services, HIV testing reminding had the biggest factor loading of 0.88. Psychological status scores played a negative role in HIV testing behaviors among MSM with the path coefficient value of -0.33.Conclusions:The awareness and testing rate of HIV among MSM population need to be further improved. While effective measures are implemented to promote HIV testing among MSM, more attention should be paid to the mental health problems of MSM.
