Frequent HIV Testing: Impact on HIV Risk Among Chinese Men Who Have Sex with Men.

ABSTRACT: BACKGROUND:The HIV epidemic continues to expand among men who have sex with men (MSM) in China. The NIMH Project Accept/HPTN 043 trial suggested a borderline significant trend toward HIV incidence reduction among persons with higher testing rates. METHODS:We assessed HIV testing histories and infection status among a community-based Beijing MSM. HIV serostatus was lab confirmed. We ascertained demographic/behavioral factors through questionnaire-based interviews. Associations of previous HIV testing with odds of current HIV infection were assessed, seeking improved like-with-like risk comparisons through multivariable logistic regression analysis with propensity score adjustment and restricted cubic spline modeling. RESULTS:Among 3588 participants, 12.7% were HIV infected; 70.8% reported having ever tested for HIV. Compared with MSM who never tested, those ever testing had a 41% reduction in the odds of being HIV positive [adjusted odds ratio (aOR): 0.59; 95% confidence interval (CI): 0.48 to 0.74. Higher HIV testing frequencies were associated with a decreasing trend in the odds of being infected with HIV vs. a referent group with no previous testing [>6 tests (aOR: 0.27; 95% CI: 0.18 to 0.41); 4-6 (aOR: 0.55; 95% CI: 0.39 to 0.78); 2-3 (aOR: 0.61; 95% CI: 0.45 to 0.82); P for trend <0.001]. The multivariable-adjusted model with restricted cubic spline of HIV testing frequency showed a higher frequency of previous HIV testing associated with lower odds of HIV infection, particularly among men with ?10 lifetime male sexual partners. CONCLUSIONS:Using risk probability adjustments to enable less biased comparisons, frequent HIV testing was associated with a lower HIV odds among Chinese MSM.

Project description:Migration of men who have sex with men (MSM) from rural to urban areas is common across low- and middle-income countries and is widely believed to contribute to elevated HIV risk among migrant MSM in urban areas. Little consensus exists on whether their risk is due to their transplantation or their being from resource-constrained rural areas. This study seeks to clarify the relationship between migration and HIV risks by comparing differences in HIV-related risky sexual behaviours and healthcare utilization across competing conceptualizations of migratory statuses.In July 2016, MSM ?16 years old currently residing in one of eight urban cities in China were recruited for an online cross-sectional survey, which collected information on socio-demographics, sexual behaviours, HIV care-seeking behaviours, and healthcare utilization. Based on a question about residency status, each participant was classified as an urban local resident, urban transplant, or rural transplant. Multivariable multinomial logistic regression was used to examine the associations between risky behaviours and healthcare utilization among these three groups.Among 2007 MSM, the proportion of local, urban transplant and rural transplant were 32% (648/2007), 24% (478/2007), and 44% (881/2007), respectively. Compared with urban local resident MSM, urban transplant MSM were more likely to have ever tested for HIV (adjusted odds ratio (aOR) = 1.39, 95% confidence interval (CI): 1.08 to 1.80). Compared with urban transplant MSM, rural transplant MSM were less likely to have utilized any governmental sexual health services in the past three months (aOR = 0.75, 95% CI: 0.60 to 0.93), ever tested for HIV (aOR = 0.77, 95% CI: 0.61 to 0.96), ever initiated antiretroviral therapy (ART) (aOR = 0.16, 95% CI: 0.05 to 0.52), and ever purchased sex (aOR = 0.57, 95% CI: 0.38 to 0.85). No other significant differences were found in sexual behaviours among three groups.The widely used local/migrant categorization obscures important differences in HIV risk present between urban/rural subgroups among them. Previous studies of HIV risks in Chinese "migrant" may have failed to consider the role of structural factors such as discrimination or barriers to healthcare when interpreting their findings of higher HIV prevalence in this population. Low ART uptake among rural transplant MSM in this study is particularly concerning and underscore the need for HIV-related interventions tailored for this group.

Project description:BackgroundIncreasing human immunodeficiency virus (HIV) testing is critical for HIV control. This study aimed to evaluate the interaction between social norms and self-efficacy on HIV testing among Chinese men who have sex with men (MSM).MethodsWe conducted an online survey in eight Chinese cities in Shandong and Guangdong Provinces in July 2016. We included participants who were born as a male, at least 16 years old, currently living in one of the designated cities, and had ever engaged in anal sex with a man. We collected information regarding socio-demographics, high-risk behaviors, and history of HIV and other STI testing. We coded sensitivity to social norms using six items asking participants about their perceived social norm regarding HIV testing. We coded HIV testing self-efficacy using a separate six-item scale. We interpreted higher mean scores as higher sensitivity to social norms and higher self-efficacy, respectively. We conducted logistic regressions to evaluate the interaction between self-efficacy and social norms on HIV testing.ResultsA total of 2105 men completed the survey. The mean age of the participants was 25.97 ± 6.42 years. Over four-fifths (85.9%) of participants were unmarried, 22.7% were students, and 64.6% at least had a college degree. 62.5 and 32.6% of participants ever and tested HIV in the last three months, respectively. With respect to uptake of HIV testing in the last three months, the adjusted odds ratio was 1.01(95% CI: 0.96-1.06) for higher sensitivity to social norms and 1.09 (95% CI: 1.05-1.14) for higher self-efficacy, with an interaction effect of 1.02 (95% CI: 1.01-1.03), respectively. With respect to uptake of lifetime HIV testing, the adjusted odds ratio was 1.03(95% CI: 0.99-1.07) for higher sensitivity to social norms and 1.15 (95% CI: 1.11-1.19) for higher self-efficacy, with an interaction effect of 1.02 (95% CI: 1.01-1.04), respectively.ConclusionsOur survey demonstrated that there is a significant association between the uptake of HIV testing with sensitivity to the social norm, higher self-efficacy, as well as the interaction between them. Tailored studies for improving HIV testing among MSM in China can combine these two interventions together.

Project description:BACKGROUND:In Perú, HIV disproportionately affects men who have sex with men (MSM). Despite widespread access to treatment, the high rate of new HIV infections has remained unchanged over the last decade. Low knowledge of HIV status associated with late diagnosis is a key factor underlying the high HIV incidence observed in this setting, creating conditions for efficient onward transmission. Improving access to HIV testing and prevention services for those at highest risk is an important public health priority. Sex-on-premise venues (SOPVs) - saunas, sex clubs, pornographic movie theaters, hourly hotels, and bars/discos with areas where sex is permitted - may be opportune sites for outreach; however, further research on SOPVs and the populations who frequent them is needed to inform such efforts. METHODS:We conducted a cross-sectional online survey of adult MSM in Lima, Perú to evaluate patterns of SOPV attendance, associated sexual risk behaviors, and attitudes toward SOPV-based interventions. Participants were recruited through outreach to social media networks affiliated with local LGBTQ-aligned community groups. Our primary analytic objective was to estimate the association of HIV-related sexual risk behaviors and SOPV attendance. Additionally, we performed exploratory analyses to describe risk behavior stratified by SOPV category and to examine the relationship between SOPV attendance and the use of online platforms to meet sex partners. RESULTS:Overall, 389 MSM completed the survey from November 2018 through May 2019, of whom 68% reported attending an SOPV in the last 3 months. SOPV attendance was associated with multiple sexual risk behaviors, including transactional sex, group sex, substance use around the time of sex, and higher number of partners. Over two thirds of SOPV attendees indicated they would accept HIV testing if offered at SOPVs. CONCLUSIONS:SOPV attendance was common among MSM in Lima who participated in our survey, and SOPV attendees reported significantly greater engagement in sexual risk behaviors related to HIV transmission. Attitudes toward hypothetical SOPV-based interventions were generally favorable. These findings suggest that outreach at SOPVs may be an effective mechanism for reaching a particularly high-risk sub-population of MSM in Perú to deliver targeted HIV testing and prevention interventions.
