HIV prevalence has increased continuously, and the age groups most afflicted by the epidemic have also shifted to people aged above 50 years. Informed by the theory of HBM, we aimed to investigate related factors associated with regular HIV testing behavior. Cross-sectional data were collected using online questionnaire from geosocial networking (GSN) mobile application (apps) for MSM during May 2020 (N = 1259). Data were analyzed by univariate and multivariate logistic regression. Around 62.0% (n = 781) had received HIV testing before. Participants being divorced/widowed (AOR = 1.5,95%CI:1.1–2.0), being aware of HIV/AIDS-related knowledge (AOR = 1.8,95%CI:1.4–2.3), having disclosed sexual orientation (AOR = 1.9,95%CI:1.5–2.5), ever had sexually transmitted infections symptoms (STIs)before (AOR = 2.4,95%CI:1.8–3.2), having had≥2 sexual partners (AOR = 1.8,95%CI:1.4–2.3) and with high self-efficacy (AOR = 1.1,95%CI:1.0–1.1) were more likely to receive HIV testing. Findings suggest that many Chinses MSM aged 50 and above have not been tested for HIV. Interventions for promoting HIV testing should focus on expanding scales of HIV/STIs screening, providing HIV/AIDS-related knowledge, creating a more supportive social environment and improving self-efficacy of HIV testing.

Objectives: Accumulating evidence suggests that there may be differences in sexual behaviors, condom use, and HIV prevention service utilization (e.g., HIV testing, PrEP use) between gay and bisexual men, but this remains under-explored, especially among gay and bisexual men in China. Methods: We surveyed 4,142 gay and bisexual men on a geosocial networking app in China. Results: In adjusted model, bisexual men were less likely to have received HIV testing in their lifetime (AOR =.62, 95% CI [.53,.72]) or to have received a recent HIV test (AOR =.78, 95% CI [.68,.90]). Conversely, among those who reported having had anal sex in the past six months, bisexual men were more likely to report consistent condom use than gay men (OR = 1.38, 95% CI [1.17, 1.62]). Compared with gay men, bisexual men were significantly less likely to be aware of PrEP (AOR =.62, 95% CI [.52,.74]) and significantly less willing to use PrEP (AOR =.58, 95% CI [.46,.73]). Conclusions: Tailored HIV prevention interventions are needed to address bisexual men's needs in the context of the unique sociocultural influences on sexual behavior in China. [ABSTRACT FROM AUTHOR]
