Objective. This is the first study in China to examine the use of nitrite inhalants and its correlates among men who have sex with men (MSM) in Beijing, China.Methods. A cross-sectional survey was conducted in 2012. Structured interviews collected data on demographics, sexual and drug use behaviors, and the use of HIV services. Blood specimens were collected and tested for HIV and syphilis.Results. A total of 400 MSM eligible for the study were between 19 and 63 years of age and overall HIV prevalence was 6.0% (9.0% among nitrite inhalant users and 3.3% among nonusers). Nearly half (47.3%) of them reported ever using nitrite inhalants and 42.3% admitted using nitrite inhalants in the past year. Multivariable logistic analysis revealed that ever using nitrite inhalants in the past was independently associated with being aged≤25years, having higher education attainment, seeking sex via Internet, having casual partners in the past three months, and being HIV positive.Conclusion. The use of nitrite inhalants was alarmingly prevalent among MSM in Beijing. The independent association of the nitrite inhalant use with more casual sex partners and HIV infection underscored the need for intervention and prevention of nitrite inhalant use.

Abstract Background Recreational drug use is popular among men who have sex with men (MSM), while there is limited information about polydrug use and its consequent impact on sexual health and human immunodeficiency virus (HIV) acquisition. Methods MSM were recruited from a multicenter cross-sectional survey conducted in seven Chinese cities. Participants were divided into four subgroups based on the number of recreational drugs (RDs) used in the past 6 months. “Polydrug use” was defined as simultaneous use of ≥2 types of RDs. Information on demographics and HIV high-risk behaviors (HIV-HRBs) was collected, and blood samples were tested for recent HIV infection by the BED capture enzyme immunoassay. Results A total of 4,496 Chinese MSM participated, of which 28.4% used RDs, and 5% were polydrug users. Polydrug users commonly took poppers with one or more types of other RDs (e.g. methamphetamine). Polydrug users were likely to be aged 26–30 years, have low educational attainment, be internal migrants, have a high monthly income, use versatile positions during anal intercourse, and have inadequate knowledge about prevention of HIV infection (P<0.05 for all). As the number of RDs used in the past 6 months increased, the prevalence of HIV-HRBs increased (P<0.05 for all). The odds of recent HIV infection were higher among those who used one type (aOR = 2.2, 95%CI: 1.5–3.0) or two types of RDs (2.3, 1.0–5.2) in the past 6 months compared with those who did not use RDs. The population-attributable fractions of most HIV-HRBs for recent HIV infection were higher among polydrug users compared with those who used only one type of RD or used no RD in the past 6 months. Conclusion The level and pattern of polydrug use among Chinese MSM were different from developed countries. Polydrug use had a dose-effect relationship with HIV-HRBs. Polydrug users who have greater levels of RDs use are more likely to engage in various sexual risks, thus may associated with new HIV infections.

ObjectiveTo examine the trends of HIV prevalence, risk behaviours and HIV testing among men who have sex with men (MSM) in Nanjing.DesignFive consecutive cross-sectional surveys.SettingNanjing, China.Primary and secondary outcome measuresHIV and syphilis prevalence, HIV testing rate and factors associated with HIV infection; demographic characteristics and behaviours.Results649, 669, 577, 633, 503 MSM were recruited from 2013 to 2017. HIV prevalence was 9.9%, 12.3%, 12.5%, 9.8% and 10.1%, respectively. Syphilis prevalence decreased with a range from 10.6% to 5.6%. Risk behaviours like unprotected anal intercourse (UAI) and unprotected virginal sex in the past 6 months decreased, but multiple sex partners and ever used rush popper rose significantly. MSM tested for HIV in the previous year remained stable from 57.0% to 64.1% (P=0.633). Multivariate analysis showed that tested for HIV in the past year was protective factor against HIV infection. MSM who had UAI in the past 6 months, sex role as receptive and dual, diagnosed with sexually transmitted diseases (STDs) in the past year and currently syphilis infected were risk factors for HIV infection.ConclusionsWe observed stable high HIV prevalence, a steady HIV testing rate, decreasing syphilis prevalence and UAI among MSM in Nanjing. However, rush popper use rose dramatically. The HIV preventive strategies for MSM including condom promotion, HIV testing expansion and reduction of rush popper use, STDs screening and standardised treatment should be strengthened.

HIV prevalence is still rapidly increasing among Chinese men who have sex with men (MSM). The Internet also makes it easier for MSM to have casual partners. This study aims to evaluate the trend of Internet-based sex-seeking behavior of MSM and its impact on HIV prevalence, the distribution of HIV subtype strains, and transmitted drug resistance rates. A serial cross-sectional study was conducted from 2009 to 2014. Of the 1,981 MSM, 50.5% (1,000/1,981) mainly sought homosexual partners through the Internet (Internet-based MSM, IBM). The proportion of IBM among total MSM subjects increased from 43.3% to 61.5% (p<0.001). HIV prevalence of IBM increased from 5.7% to 20.7%, while that of non-Internet-based MSM (NIBM) increased from 7.0% to 14.7%. A relative higher proportion of NIBM were infected with HIV CRF01_AE subtype than IBM (79.5% versus 72.2%, p=0.52). Multivariable analysis found IBM had a significantly higher HIV prevalence than NIBM (13.2% versus 10.5%, aOR = 1.4, 95% CI [1.0–1.9]). Being a migrant non-Shenyang resident MSM (aOR = 1.9, 95% CI [1.3–2.9]) and occasionally/never using condoms with casual homosexual partners (aOR = 1.7, 95% CI [1.1–2.6]) were two distinct risk factors for HIV infection in IBM. More efforts should be targeted towards developing interventions aimed at IBM, particularly migrant MSM and who engage in UAI with casual homosexual partners.

Abstract Purpose: To assess the eye care practices, knowledge and attitudes of glaucoma patients identified at community eye outreaches (CEO) in Nigeria. Methodology: This was a mixed method study. The quantitative component was a cross sectional survey of patients with suspected glaucoma identified at routine CEO in South West Nigeria. Surveys were administered by trained personnel and gathered information on knowledge and attitudes toward glaucoma. The qualitative component consisted of structured interviews with providers to assess their knowledge and perspectives of glaucoma patients’ attitudes and behaviors. Results: A total of 1881 patients were screened at 24 outreaches in South West Nigeria, among which 120 glaucoma cases/suspects were identified. Fifty-six (46.7%) of the glaucoma patients were aware of glaucoma and only 39 (32.5%) patients could answer at least one knowledge question correctly. Predictors of awareness of glaucoma were minimum of secondary school education (adjusted odds ratio [OR] 9.76; 95% confidence interval [CI] 3.18-29-92) and having had an eye check-up in the past (adjusted OR 6.22; 95% CI 1.96 – 19.78). More than half 55.8% had attended an eye outreach in the past and 34.2% did not follow up at the main hospital. Patients said cost and ‘not knowing the disease was serious’ were reasons for not following up at the main hospital. Health workers interviewed said cost and poor knowledge were the main reasons glaucoma patients frequently attended free screening outreach events rather than seeking definitive care.Conclusion: Although community eye outreaches improves access to eye care, provision of appropriate health education programs and strengthening of the health insurance scheme are needed to improve its impact in glaucoma care.

ObjectivesTo estimate HIV prevalence and associated risk factors among men who have sex with men (MSM) in Dar es Salaam, Tanzania following the implementation of the national comprehensive package of HIV interventions for key population (CHIP).DesignA cross-sectional survey using respondent-driven sampling.SettingDar es Salaam, Tanzania’s largest city.ParticipantsMen who occasionally or regularly have sex with another man, aged 18 years and above and living in Dar es Salaam city at least 6 months preceding the study.Primary outcome measureHIV prevalence was the primary outcome. Independent risk factors for HIV infection were examined using weighted logistics regression modelling.ResultsA total of 777 MSM with a mean age of 26 years took part in the study. The weighted HIV prevalence was 8.3% (95% CI: 6.3%–10.9%) as compared with 22.3% (95% CI: 18.7%–26.4%) observed in a similar survey in 2014. Half of the participants had had sex with more than two partners in the month preceding the survey. Among those who had engaged in transactional sex, 80% had used a condom during last anal sex with a paying partner. Participants aged 25 and above had four times higher odds of being infected than those aged 15–19 years. HIV infection was associated with multiple sexual partnerships (adjusted OR/AOR, 3.0; 95% CI: 1.8–12.0), not having used condom during last sex with non-paying partner (AOR, 4.1; 95% CI: 1.4–7.8) and ever having engaged in group sex (AOR, 3.4; 95% CI: 1.7–3.6).ConclusionHIV prevalence among MSM in Dar es Salaam has decreased by more than a half over the past 5 years, coinciding with implementation of the CHIP. It is nonetheless two times as high as that of men in the general population. To achieve the 2030 goal, behavioural change interventions and roll out of new intervention measures such as pre-exposure prophylaxis are urgently needed.

Abstract Background The human immunodeficiency virus (HIV) epidemic has been drastically increasing among men who have sex with men (MSM) in China over the past decade. More so, the number of HIV infections among young adults in the country has also been on the rise, highlighting a unique sub-population, which may lead to increased incidence and transmission of the disease. This study aimed to determine the HIV infection rate amongst student and non-student young men who have sex with men (YMSM) in three regions in China and factors associated with their HIV infection. Methods A cross-sectional study was conducted from 1 September to 6 September 2017 in Beijing, Sichuan, and Guangzhou). Participants were recruited through a popular Chinese gay social networking application, as well as several college-based youth associations. Univariate and multivariate logistic regression analyses were conducted to assess factors associated with HIV infection. Results The HIV infection rate among non-student YMSM was significantly higher than that of student YMSM (10.3% versus 5.3%, χ2trend=17.34, P<0.001). The multivariate logistic regression analysis showed that YMSM self-identifying as homosexual (AOR=2.81, 95%CI=1.40-5.66, P=0.004) and perceived themselves at risk for HIV (AOR=3.08, 95:CI:1.33-7.15, P=0.009) had a 3 times increased odds of being HIV positive. Additionally, participants whom reported not always using condoms with sex partners in the past six months (AOR=1.69, 95%CI=1.17-2.44, P=0.006) were at increased odds of HIV infection. Conclusions Young men who have sex with men, particularly those identifying as homosexual and not always using condoms during intercourse, are at increased odds of HIV infection in China. Promoting comprehensive sexual education to youth and other measures aimed at improving HIV knowledge could help control HIV transmission among this key sub-population.

BACKGROUND Finding casual sex partners on the Internet has been considered as a new challenge for HIV transmission among men who have sex with men (MSM). OBJECTIVE To identify the characteristics and risk factors of men who have sex with men (MSM) finding casual sex partners on the Internet for a new challenge regarding HIV transmission. METHODS This was a cross-sectional study. Participants were enrolled by four community-based organizations (CBOs) through bathroom, bar and gay applications. Online survey was conducted to collected information on finding casual sex partners, HIV knowledge, HIV-risk behaviors. RESULTS Among 767 participants, 310(40.4%) reported ever finding causal sex partners on the Internet. Factors associated with finding casual sex partners online in multivariate logistic regression analysis included watching pornographic videos on the Internet more than once per week (adjusted odds ratio (aOR) = 1.881, 95% CI: 1.201–2.948), discussing “hooking-up online” with friends (aOR = 4.018, 95%CI: 2.910–5.548), and perceiving that the likelihood of HIV infection in online casual sex partners was “very high” (aOR = 2.034, 95%CI: 1.441–2.873) or “high/medium/low” (aOR = 2.548, 95% CI: 1.524–4.259). Among the 310 participants who reported finding casual sex partners online, 30.2% reported having unprotected sex with casual sex partners met online in the past 6 months. In multivariate logistic regression analysis, knowing the HIV infection status of online casual sex partners was significantly associated with a decreased risk of inconsistent condom use (aOR = 0.327, 95% CI: 0.167–0.642). CONCLUSIONS Internet-based casual sexual behavior is becoming more prevalent, and the rate of unprotected sex among MSM in Zhejiang Province is high. Future HIV prevention approaches should emphasize the importance for MSM of proactively determining the HIV infection status of potential online casual sex partners.
