Factors associated with regular HIV testing behavior of MSM in China: a cross-sectional survey informed by theory of triadic influence

Abstract

The prevalence of HIV infection among men who have sex with men (MSM) in China has increased in recent years. Regular HIV testing is a key prevention strategy for identifying HIV infections among MSM. Informed by the theory of triadic influence, we aimed to determine individual, social and environmental factors associated with regular HIV testing behavior. Regular HIV testing is defined as taking an HIV test every 3 to 6 months. Both an online survey and a face-to-face survey was administered to MSM in China. Logistic regression was used to examine associations with testing behavior. 500 MSM were surveyed, the prevalence of regular testing was 56.4%. In the final model, age of first sexual intercourse, self-efficacy, perceived risk, number of partners, orientation disclosure, knowledge of HIV testing, behavioral intention and HIV relevant behaviors (sexually transmitted infection testing history) were associated with regular HIV testing; social stream characteristics had stronger associations with regular testing than individual and environmental factors. Findings implicated that interventions aimed at improving the effective counseling service from healthcare providers and the medical environment and intrapersonal changes should be combined to encourage MSM to have their first HIV test and to keep coming back at regular intervals.
