Abstract
BACKGROUND Heterosexual contact is the primary mode of HIV transmission in China and commercial sex is thought to play a crucial role in China's epidemic. Female sex workers (FSWs) in China tend to be either brothel-based (BSWs) or street-based (SSWs), but few studies have investigated the differences between these important segments of this difficult-to-reach, high-risk population. Our aim was to explore the differences between SSWs and BSWs in terms of socio-demographic characteristics, sexual and risky practices, HIV/STI-related knowledge, health services, HIV/STI prevalence and other aspects. METHODS A cross-sectional survey was conducted in Yunnan Province of China in partnership with a local FSW-friendly non-governmental organization. Face-to-face interviews using a structured questionnaire were conducted to collect data on socio-demographic characteristics, sex work history, sexual behaviours, HIV/STI-related knowledge, HIV testing history, and healthcare services uptake. Blood samples were taken for HIV and syphilis testing, and urine samples for gonorrhea and chlamydia testing. Descriptive statistics were used to evaluate differences between SSWs and BSWs. RESULTS A total of 185 BSWs and 129 SSWs were included in the study. SSWs were older and less educated, had more dependents and more clients, lower condom use and accessed fewer healthcare services. Moreover, 37.2% of SSWs and 24.9% of BSWs were found to have HIV/STI infection. Unfortunately, the awareness related to STIs was relatively low in both groups, especially SSWs. CONCLUSIONS Our study provides evidence that confirms the disproportionately high vulnerability of SSWs to HIV and other STIs, underscoring the urgent need for the Chinese health and public health sectors to prioritize outreach to SSWs. Awareness and educational programs, condom distribution, testing and health check-ups should be included in a comprehensive strategy for HIV/STI prevention in this high-risk population.

Abstract
Women engaged in sex work (WSW) in China encounter numerous disadvantages (e.g., exposure to violence) and have substantial risk for psychological distress and somatic symptoms. Intervention literature has attended to mindfulness, which is a protective factor for psychological outcomes, and its influences can further improve physical health. However, mindfulness has not been well studied in WSW. We aimed to examine the association among mindfulness, psychological distress, and somatic symptoms among Chinese WSW. Data were collected from 410 WSW in Guangxi, China, using an anonymous, self‐administered survey evaluating demographics, mindfulness, psychological distress (i.e., depression, loneliness, and perceived stress), and somatic symptoms (i.e., pain, cardiopulmonary, and gastrointestinal/fatigue symptoms). Structural equation modeling was utilized for data analyses. Mindfulness was negatively associated with psychological distress and somatic symptoms. Psychological distress was positively associated with somatic symptoms. Psychological distress mediated the association between mindfulness and somatic symptoms. Mindfulness appears to be a protective factor for psychological distress among WSW, and such an effect is further influential to their somatic symptoms. Our findings add to the growing literature on mindfulness, suggesting that mindfulness‐based interventions could be beneficial for WSW. Future research should explore other cognitive factors underlying the psychosomatic mechanism of mindfulness.

Abstract
OBJECTIVES The stigmatization of men who have sex with men (MSM) has led to an underestimation of their population size. To address this, the United Nations Programme on HIV/Acquired Immunodeficiency Syndrome and World Health Organization developed a multiplier method. However, nearly all multiplier method estimates of MSM population size in China are far below national estimates. This study explores how privacy protection to address and avoid MSM stigmatization can affect reliable estimates. METHODS Data from an MSM website, a bar, and a peer-based HIV testing were used to produce three multiplier method estimates of the MSM population size in Taiyuan, China, in 2014. The effect of privacy protection on stigmatization was explored by comparing the peer-based HIV testing with other estimates. We used a national estimate as a reference to verify potential underestimation. RESULTS The website and bar estimates were 5- to 10-times and 8- to 16-times lower than the Chinese national estimate range, respectively. Conversely, the peer-based HIV testing estimate was within the national estimate range. CONCLUSIONS Though the multiplier method was developed to estimate the size of stigmatized populations, it might be affected by privacy protection addressing stigmatization; this should be considered when gathering data.

Abstract
Nearly 17 years ago China launched its National HIV/AIDS Response Program, yet the epidemic still is not slowing. New cases and new deaths increase every year—in 2005, 40 711 people living with human immunodeficiency virus (HIV; PLWH) were diagnosed and 5729 died, whereas in 2019, 148 598 PLWH were diagnosed and 31 522 died. Moreover, the estimated PLWH population in China has risen to >1.25 million. However, epidemic data are worryingly complex and difficult to interpret, presenting challenges to the redirection and refocusing of efforts toward achievement of control. Here we present three “windows” into China’s epidemic data. From these viewpoints, it appears we still do not know how much infection exists, how much transmission is occurring, and in what contexts transmission happens. The enigma that is China’s HIV epidemic must be better understood. A new research agenda must be developed and executed if we are to change the future of HIV in China.

Abstract
Background The purpose of this study was to research the molecular transmission and genetic evolutionary characteristics among CRF07_BC-infected patients in a developed area in Eastern China. Methods Plasma samples from newly diagnosed HIV-1-positive patients from 2015–2018 and basic demographic and epidemiological information were obtained. Pol sequences from CRF07_BC-infected patients were selected for phylogenetic, molecular transmission network, and Bayesian evolutionary analyses. Results Pol sequences were successfully obtained from 258 samples of CRF07_BC. Phylogenetic analysis revealed 2 distinct lineages: lineage 1 (66.3%, 171/258), primarily from men who have sex with men (MSM) and some heterosexual individuals, and lineage 2 (33.7%, 87/258), primarily from heterosexual individuals. Under an optimal genetic distance of 0.01 substitutions/site, 163 individuals (63.2%, 163/258) formed 23 groups comprising 6 clusters and 17 dyads in the networks. A distinctly large and rapidly growing cluster (C1) containing 105 individuals was identified, in which MSM with ≥4 links had quite a high transmission risk (low educational background, active sexual behavior, low sexual protection awareness, etc.). According to Bayesian analyses, most C1 clades formed from 2005 to 2009, most of which were closely geographically related to CRF07_BC epidemic strains from Anhui province. Conclusions Here, we elucidated the local transmission characteristics and epidemic pattern of HIV-1 CRF07_BC, revealing that MSM (especially with ≥4 links) may be a significant driver in the formation of active and rapid growth networks in regional CRF07_BC epidemics. Thus, unique region– and risk group–specific transmission network analysis based on a molecular approach can provide critical and insightful information for more effective intervention strategies to limit future HIV-1 transmission.

Abstract
Background Male clients of female sex workers ('clients' hereafter) are considered high-risk and potentially a bridge population in the HIV epidemic. Non-occupational post-exposure prophylaxis (nPEP) is a safe and effective but under-utilised public health intervention to prevent HIV transmission. This study aims to explore clients' awareness of nPEP, intention of uptake, potential barriers to nPEP uptake and adherence, and suggestions for nPEP promotion in China. METHODS We conducted semi-structured in-depth interviews with 20 clients in two Chinese cities in 2018. Participants were recruited through purposive sampling. The content of the interviews was analysed using thematic content analysis in ATLAS.ti. RESULTS Overall, just a minority of participants were aware of nPEP. A majority expressed willingness to use nPEP. Potential barriers to nPEP uptake and adherence included adverse drug reactions, price, concerns of drug efficacy, privacy issues, and forgetting to take the drugs. Almost all participants expressed the need to promote nPEP among clients. Participants suggested that the promotion of nPEP should be at hospitals, online, and be integrated with HIV/AIDS health education. CONCLUSIONS Our findings suggested that nPEP guidelines should be formulated and implementation strategies should be developed to address barriers to uptake and adherence in order to successfully tap into the potential of nPEP as an effective HIV prevention tool.

Abstract
PURPOSE OF REVIEW This review aims to describe the epidemiology of HIV among female sex workers (FSWs) in China over the past decade, to summarize current gaps in knowledge regarding risk factors, and to identify new directions for HIV prevention strategies. RECENT FINDINGS We summarized national and regional levels of HIV prevalence among FSWs based on reported rates in the literature from 2008 to 2018. Studies identified cases of HIV infection among FSWs in all but one province during this time period, and demonstrated a sporadic pattern in most provinces, with a low overall national HIV prevalence below 1%. However, in Yunnan and Guanxi Zhuang Autonomous Regions, the median-reported prevalence rates were close to or slightly above 1%. National prevention programs have widely promoted male condoms as a primary and practical measure for HIV prevention, but studies evaluating condom use practices among FSWs demonstrated wide variability. A rise in illicit use of synthetic drugs and changing sexual practices in the setting of sex work (e.g., anal sex) may represent newer risk factors for HIV transmission among FSWs; however, more data are needed to better characterize these trends. Limited studies have examined the feasibility and efficacy of innovative prevention tools (e.g., female condoms) or strategies (e.g., pre-exposure prophylaxis, PrEP) to prevent HIV among FSWs. We call for a more comprehensive understanding of current trends in HIV risk among FSWs, as well as more research focuses on innovative strategies to reduce the spread of HIV in this vulnerable population.

Abstract
OBJECTIVES To explore the prevalence and changing trends of HIV, syphilis, hepatitis C virus (HCV) infections and risk behaviours among female sex workers (FSWs) and to provide reference and theoretical basis for formulating targeted interventions. DESIGN Six consecutive cross-sectional surveys. SETTING Chongqing, China. PARTICIPANTS FSWs were included if they (1) were aged ≥16 years, (2) provided commercial sex for money or goods during the previous month and (3) were willing to participate in the survey and could provide verbal informed consent. This study included 16 791 of 16 810 participants recruited between 2013 and 2018. PRIMARY AND SECONDARY OUTCOME MEASURES The prevalence of HIV/syphilis/HCV infection. RESULTS The HIV and HCV prevalence among FSWs in Chongqing was stable during the study period, but the prevalence of syphilis had an increasing trend, particularly among low-tier and middle-tier FSWs. Improvements in HIV-related knowledge, condom use, injecting drug use and participation in HIV-related services were observed. However, no change was found in the prevalence of drug use. HIV infection was correlated with no condom use in the last commercial sex (adjusted OR (aOR) 3.48, 95% CI 1.90 to 6.37) and syphilis infection (aOR 4.88, 95% CI 1.95 to 12.18). Syphilis infection was correlated with inconsistent condom use (aOR 1.30, 95% CI 1.02 to 1.65), HIV infection (aOR 5.88, 95% CI 2.40 to 14.41), HCV infection (aOR 7.68, 95% CI 4.37 to 13.49) and sexually transmitted infection (STI) diagnosis in the past year (aOR 3.81, 95% CI 2.40 to 6.03). HCV infection was associated with injecting drug use (aOR 8.91, 95% CI 4.45 to 17.86) and syphilis infection (aOR 7.88, 95% CI 4.49 to 13.83). CONCLUSIONS Comprehensive interventions targeting FSWs, particularly low-tier and middle-tier FSWs, should be increasingly implemented to prevent and control HIV, syphilis and other STIs.

Abstract
OBJECTIVE United Nations Programme on human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome and World Health Organization believe that some of the benchmark numbers collected may be inaccurate when using the multiplier method to estimate the size of populations most at risk of acquiring HIV. Here, study data have been evaluated to characterize the inaccurate benchmark numbers. STUDY DESIGN The study design used is a systematic review. METHODS Studies published from 1 January 2004 to 1 December 2019 using the multiplier method to estimate the population proportions of men who have sex with men (MSM) and female sex workers (FSWs) in China were reviewed. Five electronic bibliographic databases were searched: Medline, the China National Knowledge Infrastructure, VIP Database for Chinese Technical Periodicals, Wanfang Data, and the Chinese BioMedical Literature Database. RESULTS In all eight studies of FSW, six of the estimated population proportions fell within the range of national estimates. However, the estimated MSM population proportions of all 18 studies fell outside the range of national estimates. CONCLUSIONS When estimating the MSM population, the use of benchmark numbers from homosexual websites or MSM-frequented sites usually led to an inaccurate estimation. Therefore, benchmark numbers from services/programs that meet fundamental needs, such as those dealing with health and wellness, should be used.

Abstract
Stigma towards men who have sex with men (MSM) is prevalent, and many MSM are married to women. This study aims to provide acomprehensive understanding of coping strategies and the need for support among women in serodiscordant relationships with MSM living with HIV. We conducted 19 qualitative in-depth interviews with these women living in Sichuan, China. Semi-structured interviews were recorded and transcribed. Qualitative data were transcribed verbatim and analyzed using content analysis. We found that these women utilized multiple coping strategies both within the family and externally. Coping strategies within the family included keeping husbands' HIV diagnosis confidential, integrating husband's HIV treatment management into family routines, restoring spousal relationship, protecting themselves from HIV infection, denying, self-blaming, and persuading the husbands to see the psychiatrist due to homosexual behaviors. Coping strategies outside the family included seeking information from multiple sources, peer support, and online support. Participants expressed needs for more information, psychological support, stigma reduction, and special counseling on how to handle their husband's homosexual identity and/or behavior. Women married to MSM living with HIV develop both adaptive and maladaptive coping strategies, and the majority of these women's needs are unmet under the current service system in China.

Abstract
The human immunodeficiency virus (HIV) infection rate for men who have sex with men (MSM) has rapidly increased in recent years in China and the migrant population accounts for a large proportion of this increase. The migration of MSM not only poses difficulties for government departments charged with treating the disease, but also increases the spread of HIV in geographical space, so it is important to understand the geographical distribution and migrant patterns of MSM. We searched the largest dating website in China to obtain open information from all users in the Chinese mainland from January 2006 to August 2017. For the analysis, the datasets were merged according to units of time and administrative regions. In total, 1,356,609 records were obtained for this study. The main users of the website were single males aged 18-35 years old. Most of the users were located in the large and mid-sized cities of East China. The distribution of MSM was strongly associated with the distribution of the development of service industry in geographical space. The main flow of MSM are mainly located inside the province as internal flow. For those MSM who prefer to migrate to other provinces, the Beijing-Tianjin-Hebei area, the Yangtze River Delta, the Pearl River Delta, and Sichuan and Chongqing area were their primary destinations. The interprovincial migration behavior of MSM was closely related to an increased average income. MSM prefer to migrate to cities with developed economies and open cultures. It is important to strengthen the management of migrant MSM and increase their basic understanding of HIV.

HIV Prevalence and Factors Influencing the Uptake of Voluntary HIV Counseling and Testing among Older Clients of Female Sex Workers in Liuzhou and Fuyang Cities, China, 2016-2017: A Cross-Sectional Study. BIOMED RESEARCH INTERNATIONAL 2020; 2020:9634328. [PMID: 32185227 PMCID: PMC7060410 DOI: 10.1155/2020/9634328] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 09/11/2019] [Revised: 12/22/2019] [Accepted: 02/10/2020] [Indexed: 12/22/2022]
Abstract
Objective To compare the prevalence of HIV and associated factors for participating HIV voluntary counseling and testing (VCT) among older clients of female sex workers (CFSWs) in Liuzhou City and Fuyang City in China. Methods A cross-sectional study was conducted and the study employed 978 male CFSWs, aged 50 years and above from October 2016 to December 2017. All participants were required to complete a questionnaire and provide blood samples for HIV testing. Multivariate logistic regression analysis was used to analyze the influential factors of using VCT program and tested for HIV. Results The HIV infection prevalence rate was 1.2% and 0.5%, while 52.3% and 54.6% participants had ever utilized VCT service and tested for HIV in Liuzhou City and Fuyang City, respectively. The older CFSWs who ever heard of VCT program were more likely to uptake VCT program in both cities (ORLiuzhou = 2.224, ORFuyang = 2.421). Participants, whose marital status was married or cohabiting (ORLiuzhou = 0.548, ORFuyang = 0.495), who have stigma against individuals who are living with HIV/AIDS (ORLiuzhou = 0.273, ORFuyang = 0.371), whose monthly income is more than 500 yuan (ORLiuzhou = 0.622, ORFuyang = 0.600), and whose age is more than 60 years old (ORLiuzhou = 0.639, ORFuyang = 0.554), were less likely to visit VCT clinics. Those who are worried about HIV-infected participants were more likely to utilize VCT services in Fuyang City (AOR = 1.838, 95%CI : 1.146‐2.948). Conclusion Combine strategy will be needed to promote the utilization of VCT service, based on the socioeconomic characteristics of older male CFSWs in different cities of China.

Abstract
The China-US Cooperation-Global AIDS Program (GAP) was a strategic technical collaboration program jointly implemented by the US Centers for Disease Control and Prevention and the Chinese Center for Disease Control and Prevention. This program developed, piloted, launched, and evaluated a broad range of projects supporting national and local HIV prevention and control programs; evidence-based decision-making; strengthening systems and capacity at national, provincial, and local levels; prioritizing high-risk geographic areas and populations; developing innovative approaches for scale-up; answering important scientific questions that can be most effectively answered in China but also with global implications for the HIV response; and increasing China’s engagement with the global public health community and sharing critical lessons learned. A productive working relationship with well-conceived models, a results-based activity implementation plan, and proper linkage to the domestic policy process has made a significant contribution to HIV control and prevention in China.

Abstract
This study explored the impact of serostatus disclosure on the spousal relationship between wives and their HIV-positive husbands who have had sex with men. A qualitative study using semi-structured interviews was conducted in Sichuan, China in 2017 with wives (n = 31) who had known their husbands' HIV-positive status. Participants were identified by local governmental and non-governmental organizations that provide routine services for people living with HIV and their family members. Qualitative data underwent a detailed content analysis. Both positive and negative impacts on the spousal relationship were expressed by wives. Six themes were identified: (1) reduced sexual activities; (2) changes in intimacy; (3) limited communication on HIV-related issues but improved communication on other topics; (4) increased instrumental support but decreased emotional support; (5) improved resilience in the spousal relationship; and (6) shared privacy management rules regarding HIV-positive status. Moreover, the acknowledgment of the husband's homosexual behavior hurt the spousal relationship more seriously than the disclosure of the husband's HIV-positive status, and irremediable marriages were observed among wives who knew both. Disclosure of HIV-positive status had a great impact on the spousal relationship, though such impact varied across individuals.

Abstract
This study investigated the trend and associated factors of condom use among male clients of female sex workers (CFSW) in Hong Kong. A total of 25,443 males of the general population were screened to identify 2,330 CFSW via 13 rounds of population-based serial cross-sectional telephone surveys during 1998 through 2015. Over time, there were no significant changes in condom use with various types of female sex partners (p ranged 0. 219-0.837) and prevalence of self-reported STI (p = 0.975) in the past 6 months. Decrease in the prevalence of non-regular sex partners (p < 0.001) and increase in perceived efficacy of condom use for HIV prevention (p = 0.028) were observed. Perceived efficacy of condom use for HIV prevention and self-reported STI experience were significantly associated with condom use with various types of female sex partners in the past 6 months. No evident improvement for condom use was found. Tailored intervention programs are warranted.

Abstract
The aim of the study was to explore the relation of various factors with unprotected anal intercourse (UAI) and provide some insight for HIV intervention on Chinese men who have sex with men (MSM). The current cross-sectional study recruited 365 MSM in Dalian, China. More than half of the respondents (117 respondents, 51.8% of the sample) had engaged in UAI. The multivariable logistic regression model suggested that poorer mental health (AOR: 7.16; 95% CI: 3.14–16.31), self-stigma (AOR: 1.53; 95% CI: 1.00–2.34), and experience(s) of physical abuse in childhood (AOR: 5.85; 95% CI: 1.77–19.30) were significantly and positively related to UAI. Community engagement was negatively associated with UAI (p < 0.05). It appears it is necessary to incorporate mental health services, eliminate the stigma against homosexuality, and facilitate MSM-related community engagement into intervention strategies to prevent UAI among Chinese MSM. Targeted UAI interventions in the subgroup with a history of childhood physical abuse should also be of great concern.

Abstract
HIV prevalence and incidence is high among men who have sex with men (MSM) in China, underscoring the need to support and optimize HIV risk reduction strategies for this population. We sought to estimate the prevalence of condomless anal sex among MSM living in Tianjin, China. We recruited 595 HIV-negative MSM living in Tianjin to participate in a HIV study between 2013 and 2014. Data were collected after a voluntary counseling and testing session through a face-to-face survey. We used multivariable logistic regressions to examine the association between sociodemographic characteristics and HIV risk correlates and MSM's likelihood of engaging in condomless anal intercourse with main and casual partners in the prior 6 months. Results are presented. HIV risk reduction efforts should be developed to be sensitive and responsive to the unique experiences of Chinese MSM. We discuss opportunities for future work, including the development HIV risk reduction interventions.

Abstract
Background Studies have shown a recent upsurge in human immunodeficiency virus (HIV) burden among men who have sex with men (MSM) in China, especially in urban areas. For intervention planning and resource allocation, spatial analyses of HIV/AIDS case-clusters were required to identify epidemic foci and trends among MSM in China. Methods Information regarding MSM recorded as HIV/AIDS cases during 2006-2015 were extracted from the National Case Reporting System. Demographic trends were determined through Cochran-Armitage trend tests. Distribution of case-clusters was examined using spatial autocorrelation. Spatial-temporal scan was used to detect disease clustering. Spatial correlations between cases and socioenvironmental factors were determined by spatial regression. Results Between 2006 and 2015, in China, 120 371 HIV/AIDS cases were identified among MSM. Newly identified HIV/AIDS cases among self-reported MSM increased from 487 cases in 2006 to >30 000 cases in 2015. Among those HIV/AIDS cases recorded during 2006-2015, 47.0% were 20-29 years old and 24.9% were aged 30-39 years. Based on clusters of HIV/AIDS cases identified through spatial analysis, the epidemic was concentrated among MSM in large cities. Spatial-temporal clusters contained municipalities, provincial capitals, and main cities such as Beijing, Shanghai, Chongqing, Chengdu, and Guangzhou. Spatial regression analysis showed that sociodemographic indicators such as population density, per capita gross domestic product, and number of county-level medical institutions had statistically significant positive correlations with HIV/AIDS among MSM. Conclusions Assorted spatial analyses revealed an increasingly concentrated HIV epidemic among young MSM in Chinese cities, calling for targeted health education and intensive interventions at an early age.

Abstract
To compare different intervention models for promoting male circumcision (MC) to prevent HIV transmission in Western China. A total of 1690 male participants from multiple study sites were cluster randomly allocated to three-stage (Model A), two-stage (Model B), and one-stage (Model C) educational interventions. In all three interventions models, knowledge about MC significantly increased and the reported willingness to accept MC increased to 52.6% (255/485), 67.0% (353/527), and 45.5% (219/481) after intervention, respectively (P < 0.05). Rate of MC surgery uptake was highest (23.7%; 115/485) among those who received Model A intervention, compared to those who received Model B (17.1%; 90/527) or Model C (9.4%; 45/481) interventions (P < 0.05). Multivariable Cox regression analysis identified that Model A or Model B had twice the effect of Model C on MC uptake, with relative risks of 2.4 (95%CI, 1.5-3.8) and 2.2 (95%CI, 1.3-3.6), respectively. Model B was the most effective model for improving participants' willingness to accept MC, while Model A was most successful at increasing uptake of MC surgery. Self-reported attitude towards MC uptake was not strongly correlated with actual behavior in this study focusing on the general male population in Western China.

Abstract
Background. Our study aimed to assess the burden of depression and evaluate factors associated with depression and status of HIV risk behaviors among female sex workers (FSWs) in Guangdong, China. Method. We recruited FSWs from massage parlors, saunas, restaurants, hotels, hair salons, and streets in Guangdong, China, in 2014. Information on demographic characteristics, HIV testing history, and sexual behaviors was collected using a questionnaire. A blood sample was collected to test for HIV, syphilis, and HCV. A participant was defined as being depressed if she obtained 6 points or above using the 12-item General Health Questionnaire. Results. Among the 653 participants, 41.7% were 21–30 years old and 43.6% married. Overall, 52.4% were found to be depressed. FSWs who had correct syphilis related knowledge [aOR = 1.45; 95% CI: 1.04–2.03] and had primary sex partner (1.63, 1.14–2.33) were more likely to be depressed. FSWs who did not use a condom during their last sex with the primary sex partner were less likely to be depressed (0.47, 0.31–0.71). Conclusion. Our study observed high level of depression and HIV risk behaviors among Chinese FSWs. Future interventions should integrate mental health services in comprehensive interventions to prevent depression among Chinese FSWs.

HIV epidemiology and responses among men who have sex with men and transgender individuals in China: a scoping review. BMC Infect Dis 2016; 16:588.

Abstract
BACKGROUND Despite global efforts to control HIV among key populations, new infections among men who have sex with men (MSM) and transgender (TG) individuals are still increasing. The increasing HIV epidemic among MSM/TG in China indicates that more effective services are urgently needed. However, policymakers and program managers must have a clear understanding of MSM/TG sexual health in China to improve service delivery. To meet this need, we undertook a scoping review to summarize HIV epidemiology and responses among MSM and TG individuals in China. METHODS We searched MEDLINE, EMBASE and the Cochrane Library for recent studies on MSM/TG HIV epidemiology and responses. We also included supplemental articles, grey literature, government reports, policy documents, and best practice guidelines. RESULTS Overall, HIV prevalence among Chinese MSM was approximately 8 % in 2015 with a higher prevalence observed in Southwest China. TG are not captured in national HIV, STD, or other sexual health surveillance systems. There is limited data sharing between the public health authorities and community-based organizations (CBOs). Like other low and middle income countries, China is challenged by low rates of HIV testing, linkage, and retention. Several pilot interventions have been shown to be effective to increase HIV testing among MSM and TG individuals, but have not been widely scaled up. Data from two randomized controlled trials suggests that crowdsourcing contests can increase HIV testing, creating demand for services while engaging communities. CONCLUSION Improving HIV surveillance and expanding HIV interventions for Chinese MSM and TG individuals are essential. Further implementation research is needed to ensure high-quality HIV services for MSM and TG individuals in China.

Abstract
Drawing on 17 months of ethnographic fieldwork (2007-2011), this article critically examines the consequences of two global health initiatives (GHIs), the Global Fund and the Gates Foundation, on NGOs engaged in HIV/AIDS prevention and treatment among gay men in northwest China. I argue that a short-term surge in funding provided by GHIs between 2008 and 2010 exacerbated preexisting conflicts between NGOs by promoting a neoliberal process in which the state outsourced public health services to civil society organizations, deliberately encouraging a climate of competition among NGOs. I also show how GHIs encouraged the bureaucratization and medicalization of one grassroots gay NGO, channeling its activities away from broader political and social objectives and compelling the group to develop a narrower and more entrepreneurial emphasis on HIV testing and treatment. This article contributes to a deeper ethnographic understanding of the complex and perhaps unintended consequences of GHIs.

Abstract
In this article, I draw from recent developments in the anthropological literatures on kinship and care to complicate and extend analyses of Chinese queer NGOs and AIDS activism. By highlighting the practical, moral, and political dimensions of daily life and work within Chinese queer NGOs, I argue that they constitute what I call "alternative families of care" by serving as important sources of material and emotional support and care for queer men, including increasing numbers of HIV-positive men who have sex with men, in a social climate that is still largely unsupportive and hostile toward both queerness and people living with HIV/AIDS. I also show how HIV/AIDS prevention and care are additionally regarded by many Chinese queer activists as an important political strategy for demonstrating the responsibility of queer men in the face of the AIDS crisis, achieving greater recognition from the government and society, and eventually attaining increased rights, including same-sex marriage.

Abstract
BACKGROUND Men who have sex with men (MSM) are highly vulnerable to human immunodeficiency virus (HIV) infection and more likely to migrate due to widespread stigma and discrimination in China. Their mobility complicates estimation of local MSM population sizes and the provision of HIV services, and may also contribute to the spread of HIV. METHODS Between 1 January 2008 and 31 December 2012, the visits of all individuals to the largest Chinese MSM dating website were recorded. After a predesigned de-identification procedure by the website, we analyzed Internet Protocol addresses for migration patterns. Migrants were defined as individuals who were away from their registered residence for >6 months in the last 12 months. RESULTS The website contained data on 794 912 MSM eligible for the study, of which 34.5% were migrants. The median age was 26 years (range, 18-61 years), and 85.5% were unmarried. Compared with nonmigrant MSM, migrants were less likely to be married to a woman (8.6% vs 13.5%; P < .001). The 5 provinces with the highest migrant inflow ratios were Guangdong, Shanghai, Beijing, Tianjin, and Zhejiang. Eastern coastal cities were the primary destination of MSM from southwestern China. CONCLUSIONS Preferential MSM migration may influence MSM population sizes in both originating and destination provinces, particularly for provinces with uneven inflow and outflow. MSM migration from southwestern China, which has the highest HIV prevalence in this population, to coastal cities with lower prevalence may have implications for the spread of the HIV epidemic as well as HIV care services.

Abstract
In China, men who have sex with men (MSM) are the fastest growing population at risk for HIV. They face social stigma due to both MSM behavior and HIV. In addition, concern has been raised about the mental health of wives of MSM. In this cross-sectional study, the authors examine the mental health status of a sample of 135 of these women. Participants completed an Internet-administered questionnaire in Xi'an from April to June, 2012. Most were unaware at the time of marriage that their husbands were MSM. Physical abuse was frequently reported; depressive symptom and mental health (Symptom Checklist, SCL-90) scores were significantly higher than those of the general Chinese adult female population. A majority (59.8%) of women reported suicidal thoughts after discovering their husbands' MSM behavior; about 10% had attempted suicide. Multiple logistic regression revealed that women's experience with anal sex was associated with 7.8 times (95% CI: 1.3-65.9) greater odds of suicidal ideation. Also, women who demonstrated mental symptoms on the SCL-90 had 2.3 times (95% CI: 1.04-5.2) the odds of suicidal ideation. These results suggest that wives of MSM have a significant need for mental health care, suicide prevention, HIV education, and social support.

Abstract
PURPOSE - Injecting drug use is a global concern, with an estimated 16 million people who inject drugs (PWIDs) in over 148 countries. A number of Asian countries detain PWIDs for compulsory treatment. The paper aims to discuss this issue. DESIGN/METHODOLOGY/APPROACH - The authors reviewed the literature on compulsory drug treatment in seven Asian countries. FINDINGS - The authors identified 1,269 closed settings which held over 600,000 drug users in eight countries. The average detainee was aged from 20 to 30 years and was predominantly male. HIV risk behaviour continued in detention in some countries. In most countries treatment comprised physical labour, military drills. Methadone maintenance treatment and antiretroviral therapy were rarely available. No data were located to show detention in a closed setting treated drug dependency. Issues of concern were; no due legal process for the detention of drug users, lack of evidence-based drug treatment, lack of HIV prevention and treatment, abusive conditions, forced labour and exercise, arbitrary exit procedures and very high relapse rates. RESEARCH LIMITATIONS/IMPLICATIONS - The review of compulsory treatment of drug users failed to find any evaluation of effective drug treatment for detainees. Instead serious breaches in human rights conditions were evident. Prominent international organisations have called for the compulsory treatment of drug users to cease. PRACTICAL IMPLICATIONS - Many countries are spending vast amounts of funding on ineffective treatments for drug users. SOCIAL IMPLICATIONS - Funding should be directed to community-based drug treatments that have been shown to work. ORIGINALITY/VALUE - This is the largest review of compulsory treatment of drug users to date.

Abstract
To investigate the molecular subtypes of prevalent HIV-1 strains and characterize the genetics of dominant strains among men who have sex with men. Molecular epidemiology surveys in this study concentrated on the prevalent HIV-1 strains in Liaoning province by year. 229 adult patients infected with HIV-1 and part of a high-risk group of men who have sex with men were recruited. Reverse transcription and nested PCR amplification were performed. Sequencing reactions were conducted and edited, followed by codon-based alignment. NJ phylogenetic tree analyses detected two distinct CRF01_AE phylogenetic clusters, designated clusters 1 and 2. Clusters 1 and 2 accounted for 12.8% and 84.2% of sequences in the pol gene and 17.6% and 73.1% of sequences in the env gene, respectively. Another six samples were distributed on other phylogenetic clusters. Cluster 1 increased significantly from 5.6% to 20.0%, but cluster 2 decreased from 87.5% to 80.0%. Genetic distance analysis indicated that CRF01_AE cluster 1 in Liaoning was homologous to epidemic CRF01_AE strains, but CRF01_AE cluster 2 was different from other scattered strains. Additionally, significant differences were found in tetra-peptide motifs at the tip of V3 loop between cluster 1 and 2; however, differences in coreceptor usage were not detected. This study shows that subtype CRF01_AE strain may be the most prevalent epidemic strain in the men who have sex with men. Genetic characteristics of the subtype CRF01_AE cluster strain in Liaoning showed homology to the prevalent strains of men who have sex with men in other parts of China.

Abstract
OBJECTIVES To better understand risk behaviours and factors associated with low-fee female sex workers (FSW) and support HIV/sexually transmitted infections (STI) epidemic control among this key population in China. METHODS A cross-sectional study using convenience sampling to recruit 1487 eligible low-fee and medium-fee FSW was conducted in 2012 in three provinces. The participants were interviewed using a structured questionnaire and tested for HIV-1, herpes simplex virus (HSV)-2 and syphilis antibody. Log-binomial modelling was used to estimate prevalence ratios (PR) and examine factors associated with low-fee sex work. RESULTS Prevalence of HIV-1, syphilis and HSV-2 antibody positive were 0.5%, 4.8% and 27.8%, respectively. Low-fee FSW were more likely to have HSV-2 infection (adjusted prevalence ratio (APR)=1.3, 95% CI 1.1 to 1.7), but not more likely to have HIV-1 and syphilis infection compared with medium-fee FSW. Compared with medium-fee FSW, low-fee FSW were more likely to be ≥35 years of age (APR=2.1, 95% CI 1.3 to 3.6), engage in sex work ≥6 days/per week (APR=1.7, 95% CI 1.2 to 2.6), have ≥3 clients per day (APR=2.2, 95% CI 1.5 to 3.3), have clients decide condom use (APR=1.6, 95% CI 1.1 to 2.3), fail to persuade clients to use condoms (APR=1.6, 95% CI 1.1 to 2.6), express willingness to have unprotected sex in return for receipt of a higher fee (APR=1.8, 95% CI 1.2 to 2.8), have had genital symptoms in the past year (APR=1.4, 95% CI 1.1 to 1.8) and have migrated from another city. CONCLUSIONS Low-fee FSW in China have unique risks for acquiring HIV/STI, in part due to greater economic pressures. Tailored interventions targeting low-fee FSW and incorporating their prevailing perception of HIV/STI risks and condom use negotiation challenges that they face are urgently needed.

Abstract
BACKGROUND Sexually Transmitted Infections (STIs) are a global challenge. China, once said to have eradicated STIs, is now facing a rapid rise in the prevalence of HIV/STIs. This review of reviews aims to map HIV/STI risk factors among the Chinese population, with the objective of identifying risk factors to inform the formulation of effective prevention strategies. METHODS A systematic search using key terms related to HIV/STIs, risk factors and the Chinese population in both English and Chinese databases (PubMed, PsycINFO, the Cochrane Library; Wanfang data, CNKI, VIP and SINOMED) was conducted, and peer-reviewed systematic reviews on the topic from 1991 to 2014 were selected. Identified risk factors were grouped into different level determinants based on the HIV Social Epidemiology Model, and then evaluated and reported based on the PRISMA checklist. FINDINGS Of the twenty-eight reviews included, the majority were focused on well-established, individual level risk factors within key populations, with some highlighting the complexity of interacting factors (e.g., alcohol use and higher income in male migrants). While twenty-two reviews covered individual factors, only ten mentioned social factors and five had contents on structural factors. There are gaps in the evidence on social and structural level impacts of HIV/STIs, such as on stigma, discrimination, health policy, access to care, and illicit drug control policies. Migration and social expectation appear to pose a significant threat in aggravating the HIV/STI situation in China; for example, incarceration patterns indicated a significant risk of HIV/STIs for female sex workers. CONCLUSIONS Since international guidelines recommend an integrated and multi-level approach to HIV/STI prevention, a comprehensive approach targeting interventions at all levels along the continuum of care is needed to effectively curtail HIV/STI transmission in China. More research is needed to better understand the impact of socio-political interventions within a Chinese context.

Abstract
OBJECTIVE To study the awareness and acceptance of human papillomavirus (HPV) vaccination among sexually active men having sex with men (MSM) and men not having sex with men (MNSM) attending the largest sexual health clinic in Wuxi, China. METHODS A questionnaire about participants' socio-demographic characteristics and view on HPV vaccination was collected. RESULTS A total of 186 MSM and 182 MNSM were recruited. Among MSM, 12.4% were under 20 years old, 64.5% never married and 56.5% from Jiangsu Province (where Wuxi City is located); 64.0% had resided in Wuxi for over 2 years, 64.5% had high school education or more, and 83.9% had an income of 5000 RMB or less per month compared to figures of 5.5%, 50.6%, 73.6%, 54.9%, 86.8% and 64.8% among MNSM, respectively (All P values < 0.05). Among these 2 groups of men, 18.4% and 23.1% had heard of HPV; 10.2% and 15.4% had heard of HPV vaccine; and 26.2% and 20.2% would take HPV vaccine before sexual debut, respectively. MNSM were significantly more willing to take HPV vaccine than MSM (70.9 vs 34.9%, p < 0.001). Factors associated with HPV vaccine acceptance among MSM included engaging mostly in receptive anal sex (Odds ratio (OR)=3.9, 95% Confidence interval (CI): 1.8-13.5), never using a condom in anal sex in the past 6 months (3.5, 1.5-20.2), ever diagnosed with a sexually transmitted infection (STI) (3.4, 1.3-8.4) and ever receiving HIV related services (1.6, 1.1-4.4). Among MNSM these Factors included commercial sex with women (1.7, 1.2-8.6), never using a condom in commercial sex (1.6, 1.4-7.6) and STI diagnosis (2.0, 1.6-7.3). CONCLUSIONS Sexually active MSM and MNSM in Wuxi lacked knowledge of HPV and HPV vaccination. The majority of these at-risk men would not benefit from HPV vaccination as their age at first sex proceeded perceived age of vaccine uptake. Aggressive education aimed at increasing knowledge of HPV and HPV vaccination among these men is warranted.

Abstract
This study describes HIV disease burden and patterns of drug use before and during incarceration among detainees in Re-education-Through-Labour-Camps (RTLCs) in China. A cross-sectional survey of 576 men and 179 women from three RTLCs was conducted in Guangxi Province, China. Over three-quarters of study participants were detained due to drug-related offences. Over half of the women (n = 313, 54.3%) and two-thirds of men (n = 119, 66.5%) had been previously been incarcerated in a compulsory detoxification treatment centre (CDTC), and around one-third (men n = 159, 27.6%; women n = 50, 27.9%) in a RTLC. Of those surveyed, 49 men (8.5%) and one (0.6%) woman reported ever using drugs while in a CDTC and/or RTLC. Previous incarceration in CDTCs and RTLCs were associated with HIV infection among both male (OR = 2.15 [1.11–4.15]) and female (OR = 3.87 [1.86–9.04]) detainees. Being married/cohabiting with a partner (OR = 0.53, [0.30–0.93]) and being employed (OR = 0.46, [0.22–0.95]) were associated with a reduced odds of HIV infection among male detainees. A significant proportion of RTLC detainees had a history of drug use and a limited number of inmates had used illegal substances whilst in custody. Repeat incarcerations in CDTCs/RTLCs were associated with higher risks of HIV infection.

Abstract
BACKGROUND Commercial sex is one of the major modes of HIV transmission in China. Understanding HIV risk behaviours in female sex workers (FSW) is of great importance for prevention. This study aims to assess the magnitude and temporal changes of risk behaviours in Chinese FSW. METHOD Five electronic databases were searched to identify peer-reviewed English and Chinese language articles published between January 2000 and December 2012 that reported risk behaviours among FSW in China, including condom use, HIV testing, and drug use. Linear regression and Spearman's rank correlation were used to examine temporal trends in these risk factors. The study followed PRISMA guidelines for meta-analyses and was registered in the PROSPERO database for systematic reviews. RESULTS A total of 583 articles (44 English, 539 Chinese) investigating 594,583 Chinese FSW were included in this review. At last sex, condom use was highest with commercial partners (clients), increasing from 53.7% in 2000 to 84.9% in 2011. During this same time period, condom use increased with regular partners from 15.2% to 40.4% and with unspecified partners from 38.6% to 82.5%. Increasing trends were also found in the proportion of sampled FSW who reported testing for HIV in the past 12 months (from 3.2% in 2000 to 48.0% in 2011), while drug use behaviours decreased significantly from 10.9% to 2.6%. CONCLUSION During the first decade of 2000, Chinese FSWs' self-reported risk behaviours have decreased significantly while HIV testing has increased. Further outreach and intervention efforts are needed to encourage condom use with regular partners, continue promotion of HIV testing, and provide resources for the most vulnerable FSW, particularly low tier FSW, who may have limited access to sexual health and prevention programs.

Uretsky E. `Sex' - It's not only Women's Work: A Case for Refocusing on the Functional Role that Sex Plays in Work for both Women and Men. CRITICAL PUBLIC HEALTH 2015; 25:78-88.

Abstract
Mention of the term sex work often invokes images of marginalized women at risk for HIV infection. Such images, however, are counterintuitive to the functional role intended by the movement that spawned use of the terms `sex work' and `sex worker'. This article looks at the sexual practices of men in urban China to argue for a return to a functional definition of `sex work', which was originally meant to legitimize the role sex plays in work. The progenitors of this movement intended to use `sex work' as a means to legitimize sex as an income generating activity for women involved in prostitution. I show that sex can also serve a functional role in the work-related duties of men seeking economic and political success in contemporary urban China. Men in China utilize sex as one way for demonstrating the loyalty necessary to access state-owned and controlled resources in a market economy governed under a Leninist system. Overall the article demonstrates that reclaiming perception of sex work as a functional rather than behavioral category can expand its use for preventing HIV among the broad subset of people who engage in sex as part of their work.

Addiction 2015; 110 Suppl 1:40-50. [PMID: 25533863 PMCID: PMC5596174 DOI: 10.1111/add.12782] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/23/2012] [Revised: 09/19/2012] [Accepted: 09/13/2013] [Indexed: 01/23/2023]
Abstract
AIMS The objective of this study was to examine factors that predict antiretroviral therapy (ART) access among eligible, HIV-positive methadone maintenance treatment (MMT) clients. We also tested the hypothesis that sustained MMT participation increases the likelihood of accessing ART. DESIGN A nation-wide cohort study conducted from 1 March 2004 to 31 December 2011. SETTING MMT clients were followed from the time of their enrolment in China's national MMT programme until their death or the study end date. PARTICIPANTS Our cohort comprised 7111 ART-eligible, HIV-positive MMT clients, 49.2% of whom remained ART-naive and 50.8% of whom received ART. MEASUREMENTS Demographic variables, drug use history, MMT programme participation and HIV-related clinical characteristics of study participants who remained naive to ART and those who accessed ART were compared by univariate and multivariable analysis. FINDINGS Predictors of accessing ART among this cohort included being retained in MMT at the time of first meeting ART eligibility [adjusted odds ratio (AOR)=1.84, confidence interval (CI)=1.54-2.21, P<0.001] compared to meeting ART eligibility before entering MMT (AOR=0.98, CI=0.80-1.21, P=0.849) or previously entering MMT and dropping out before meeting ART eligibility. Additional predictors were CD4≤200 cells/μl when ART-eligibility requirement was first met (AOR=1.81, CI=1.61-2.05, P<0.001 compared to CD4=201-350 cells/μl), and being in a stable partner relationship (married/cohabitating: AOR=1.14, CI=1.01-1.28, P=0.030). CONCLUSIONS Retained participation in methadone maintenance treatment increases the likelihood that eligible clients will access antiretroviral therapy. These results highlight the potential benefit of colocalization of methadone maintenance treatment and antiretroviral therapy services in a 'one-stop-shop' model.

Abstract
The objective of this study was to qualitatively explore the components of social networks and their influence on condom use among female sex workers (FSWs) aged 35 years and older in China. In-depth interviews with 63 older FSWs and 6 focus group interviews with pimps and owners of roadside salons and hotels were conducted in 3 Chinese cities. The mean age of participants was 42.6 years old (SD = 6.9 years) and the mean age of starting sex work was 38.6 years old (SD = 6.6 years). Two types of networks that influenced condom use were identified: family networks (relationship with children and husbands) and workplace networks (relationship with peers, clients, pimps, and owners). Relationships between older FSWs and their children negatively influenced condom use. Low levels of network support and norms regarding condom use were observed in the relationship between older FSWs and their clients, whereas positive social support and norms were prevalent among older FSWs who had frequent contact with peers. Norms for condom use existed among pimps and owners but were counterbalanced by monetary gains. Future human immunodeficiency virus (HIV) interventions for older FSWs should take the different features of social network components into consideration.

Abstract
We utilized Protection Motivation Theory to assess predictors of intention and behavior of consistent condom use among Chinese female sex workers (FSWs). A self-administered questionnaire was used in a cross-sectional survey among 700 FSWs in Guangxi, China. Multivariate logistic regression analysis indicated that extrinsic and intrinsic rewards, self-efficacy, and response costs predicted consistent condom use intention and behavior among FSWs. Sexually transmitted infection/ HIV prevention programs need to reduce FSWs' perceptions of positive extrinsic rewards and intrinsic rewards for engaging in consistent condom use, reduce FSWs' perception of response costs for using a condom, and increase condom use self-efficacy among FSWs.

Abstract
OBJECTIVE To determine the prevalence of infections with HIV and hepatitis C virus (HCV), and of syphilis among female sex workers (FSWs) in Liuzhou, China, along with levels of HIV-related knowledge and frequencies of risk behaviors. METHODS A cross-sectional survey was conducted between July 2012 and January 2013. FSWs (aged ≥16 years; reported receiving payment for sex in previous 6 months) working at 58 selected commercial sex establishments (level 1 [>¥300 per transaction], level 2 [¥100-300], or level 3 [<¥100]) completed a questionnaire and provided blood samples for testing. RESULTS Of 622 participating FSWs, 7 (1.1%) had HIV infection, 67 (10.8%) syphilis, and 44 (7.1%) HCV infection. Consistent condom use during commercial sex encounters in the past month was reported by 412 (66.2%) FSWs. Inconsistent condom use was most likely in FSWs working in level 3 establishments (odds ratio [OR] 1.85; 95% CI 1.02-3.39), with a regular partner (OR 1.65; 95% CI 1.12-2.45), and who used illicit drugs (OR 2.10; 95% CI 1.24-3.54). Inconsistent condom use was least likely in FSWs with high HIV awareness (OR 0.29; 95% CI 0.18-0.48) and who had had a previous HIV test (OR 0.51; 95% CI 0.34-0.76). CONCLUSION Further prioritized and combined programs aimed at FSWs are needed to prevent HIV transmission in China.

Abstract
BACKGROUND Studies on the transmission of human immunodeficiency virus (HIV) and sexually transmitted diseases in female sex workers (FSWs) have been limited primarily to inferences drawn by focusing on defined geographical areas. METHODS AND FINDINGS This serial cross-sectional study was conducted in mainland China from 2008 through 2012. Data for 827 079 participants was analyzed. We classified venues such as karaoke bars and hotels as high tier and venues such as hair salons and barbershops, massage parlors, and other public outdoor venues as low tier based on the participants' socioeconomic status. FSWs who worked at the venues and those who were present on the days of the survey were recruited. The prevalence of HIV decreased from 0.6% in 2008 to 0.3% in 2012, the syphilis prevalence ranged from 2.4% to 3.2% between 2008 and 2012, and hepatitis C virus (HCV) prevalence decreased from 0.9% in 2008 to 0.8% in 2012. Further, we found that HIV, syphilis, and HCV prevalence proportions were high in FSWs from low tiers. CONCLUSIONS HIV, syphilis, and HCV prevalence among FSWs in our study decreased during the study period. Comprehensive intervention strategies, particularly those that focus on low-tier and older FSWs, are needed in order to decrease the disease burden in this population.

Gender inequality and HIV transmission: a global analysis. J Int AIDS Soc 2014; 17:19035.

Abstract
Introduction The HIV pandemic disproportionately impacts young women. Worldwide, young women aged 15–24 are infected with HIV at rates twice that of young men, and young women alone account for nearly a quarter of all new HIV infections. The incommensurate HIV incidence in young – often poor – women underscores how social and economic inequalities shape the HIV epidemic. Confluent social forces, including political and gender violence, poverty, racism, and sexism impede equal access to therapies and effective care, but most of all constrain the agency of women. Methods HIV prevalence data was compiled from the 2010 UNAIDS Global Report. Gender inequality was assessed using the 2011 United Nations Human Development Report Gender Inequality Index (GII). Logistic regression models were created with predominant mode of transmission (heterosexual vs. MSM/IDU) as the dependent variable and GII, Muslim vs. non-Muslim, Democracy Index, male circumcision rate, log gross national income (GNI) per capita at purchasing power parity (PPP), and region as independent variables. Results and discussion There is a significant correlation between having a predominantly heterosexual epidemic and high gender inequality across all models. There is not a significant association between whether a country is predominantly Muslim, has a high/low GNI at PPP, has a high/low circumcision rate, and its primary mode of transmission. In addition, there are only three countries that have had a generalized epidemic in the past but no longer have one: Cambodia, Honduras, and Eritrea. GII data are available only for Cambodia and Honduras, and these countries showed a 37 and 34% improvement, respectively, in their Gender Inequality Indices between 1995 and 2011. During the same period, both countries reduced their HIV prevalence below the 1% threshold of a generalized epidemic. This represents limited but compelling evidence that improvements in gender inequality can lead to the abatement of generalized epidemics. Conclusions Gender inequality is an important factor in the maintenance – and possibly in the establishment of – generalized HIV epidemics. We should view improvements in gender inequality as part of a broader public health strategy.

Abstract
Background Guangxi has become one of the provinces with the most severe HIV-1 epidemic in China, where heterosexual contact is the dominant transmission route. However, data of acute HIV infections and HIV incidence among female sex workers (FSWs) from low-grade venues are scant. Methods A cross-sectional survey was performed among FSWs from low-grade venues in Guangxi. HIV antibody screening was performed by rapid testing (RT). HIV antibody–negative specimens were screened by pooled nucleic acid amplification testing (NAAT) for acute HIV infections. HIV antibody-positive specimens were further analyzed by Western blot (WB), followed by an HIV-1 BED capture enzyme immunoassay (BED-CEIA) to identify the recent infections. HIV-1 incidence was estimated by the data of pooled NAAT and BED-CEIA, respectively. Results A total of 7936 FSWs were recruited and answered the questionnaires. We successfully collected the blood samples from 6469 (81.5%) participants, of which 139 (2.1%) were HIV antibody–positive and 6330 (97.9%) were HIV antibody-negative by RT. With pooled NAAT, 7 cases were found to be HIV RNA positive, representing an additional 5.0% of HIV-infected persons and an estimated HIV incidence of 1.45 (95% CI: 1.17–1.76) per 100 person years. There were 137 positive and 2 indeterminate by WB, of which 124 (90.5%) positive specimens were subjected to BED-CEIA testing identifying 28 recent infections. The HIV incidence determined by BED-CEIA testing was 1.04 (95% CI: 0.65–1.43) per 100 person years. The overall prevalence of HIV among FSWs from low-grade venues in Guangxi was 2.2% (95% CI: 1.9–2.6). Conclusions We found that the addition of HIV RNA screening to routine HIV antibody testing significantly improved the detection of HIV infection among FSWs from low-grade venues in Guangxi. Our findings also provided the useful baseline data of HIV incidence among this population for targeting local HIV prevention, intervention, monitoring and treatment.

Abstract
The field of HIV prevention has indeed progressed in leaps and bounds, but with major limitations of the current prevention and treatment options, the world remains desperate for an HIV vaccine. Sadly, this continues to be elusive, because more than 30 years since its discovery there is no licensed HIV vaccine. Research aiming to define immunological biomarkers to accurately predict vaccine efficacy have focused mainly on systemic immune responses, and as such, studies defining correlates of protection in the genitorectal mucosa, the primary target site for HIV entry and seeding are sparse. Clearly, difficulties in sampling and analysis of mucosal specimens, as well as their limited size have been a major deterrent in characterizing the type (mucosal antibodies, cytokines, chemokines, or CTL), threshold (magnitude, depth, and breadth) and viral inhibitory capacity of HIV-1-specific immune responses in the genitorectal mucosa, where they are needed to immediately block HIV acquisition and arrest subsequent virus dissemination. Nevertheless, a few studies document the existence of HIV-specific immune responses in the genitorectal mucosa of HIV-infected aviremic and viremic controllers, as well as in highly exposed persistently seronegative (HEPS) individuals with natural resistance to HIV-1. Some of these responses strongly correlate with protection from HIV acquisition and/or disease progression, thus providing significant clues of the ideal components of an efficacious HIV vaccine. In this study, we provide an overview of the key features of protective immune responses found in HEPS, elite and viremic controllers, and discuss how these can be achieved through mucosal immunization. Inevitably, HIV vaccine development research will have to consider strategies that elicit potent antibody and cellular immune responses within the genitorectal mucosa or induction of systemic immune cells with an inherent potential to home and persist at mucosal sites of HIV entry.

Abstract
OBJECTIVES Behavioral interventions are effective strategies for HIV/AIDS prevention and control. However, implementation of such strategies relies heavily on the accurate estimation of the high-risk population size. The multiplier method and generalized network scale-up method were recommended to estimate the population size of those at high risk for HIV by UNAIDS/WHO in 2003 and 2010, respectively. This study aims to assess and compare the two methods for estimating the size of populations at high risk for HIV, and to provide practical guidelines and suggestions for implementing the two methods. METHODS Studies of the multiplier method used to estimate the population prevalence of men who have sex with men in China published between July 1, 2003 and July 1, 2013 were reviewed. The generalized network scale-up method was applied to estimate the population prevalence of men who have sex with men in the urban district of Taiyuan, China. RESULTS The median of studies using the multiplier method to estimate the population prevalence of men who have sex with men in China was 4-8 times lower than the national level estimate. Meanwhile, the estimate of the generalized network scale-up method fell within the range of national level estimate. CONCLUSIONS When high-quality existing data are not readily available, the multiplier method frequently yields underestimated results. We thus suggest that the generalized network scale-up method is preferred when sampling frames for the general population and accurate demographic information are available.

Abstract
Background Sexually transmitted infections (STIs), including Hepatitis B and C virus, are emerging public health risks in China, especially among men who have sex with men (MSM). This study aims to assess the magnitude and risks of STIs among Chinese MSM. Methods Chinese and English peer-reviewed articles were searched in five electronic databases from January 2000 to February 2013. Pooled prevalence estimates for each STI infection were calculated using meta-analysis. Infection risks of STIs in MSM, HIV-positive MSM and male sex workers (MSW) were obtained. This review followed the PRISMA guidelines and was registered in PROSPERO. Results Eighty-eight articles (11 in English and 77 in Chinese) investigating 35,203 MSM in 28 provinces were included in this review. The prevalence levels of STIs among MSM were 6.3% (95% CI: 3.5–11.0%) for chlamydia, 1.5% (0.7–2.9%) for genital wart, 1.9% (1.3–2.7%) for gonorrhoea, 8.9% (7.8–10.2%) for hepatitis B (HBV), 1.2% (1.0–1.6%) for hepatitis C (HCV), 66.3% (57.4–74.1%) for human papillomavirus (HPV), 10.6% (6.2–17.6%) for herpes simplex virus (HSV-2) and 4.3% (3.2–5.8%) for Ureaplasma urealyticum. HIV-positive MSM have consistently higher odds of all these infections than the broader MSM population. As a subgroup of MSM, MSW were 2.5 (1.4–4.7), 5.7 (2.7–12.3), and 2.2 (1.4–3.7) times more likely to be infected with chlamydia, gonorrhoea and HCV than the broader MSM population, respectively. Conclusion Prevalence levels of STIs among MSW were significantly higher than the broader MSM population. Co-infection of HIV and STIs were prevalent among Chinese MSM. Integration of HIV and STIs healthcare and surveillance systems is essential in providing effective HIV/STIs preventive measures and treatments. Trial Registration PROSPERO No: CRD42013003721

Abstract
Bisexual behaviours are relatively common among men who have sex with men in China. This pilot study aims to reveal the complex processes through which such men manage their sexuality, family responsibilities and sexual behaviours in a rural Chinese setting. A total of 15 men who have sex with men were recruited by purposive sampling. Face-to-face in-depth interviews were conducted to explore participants' views about their sexual experiences and practices. The Chinese traditional moral code, family values and gender roles that form the crucial components of Confucianism were reflected in the participants' efforts to maintain familial and social harmony through a compromised form of sexual partnership. Most study participants demonstrated a mixed experience of social stigma, sexual naiveté and ignorance of HIV and sexually transmitted infections (STIs). Under cultural and family pressure, men who have sex with men entered heterosexual marriages with the intention of maintaining a balance between their collectivist (familial) obligations and their individualistic (same-sex sexual) desires. However, the opaque nature of their concurrent sexual relationships may endanger their personal health and accelerate HIV and STI transmission. Reducing the stigma and social prejudice associated with male same-sex sexual relations is essential for any culturally sensitive HIV-prevention programme to succeed in rural China.

Abstract
Few data exist on HIV disease progression and antiretroviral treatment (ART) impact among men who have sex with men (MSM) in China. Using data from the national case reporting system from 2004 to 2010, we describe changes in CD4 cell count before and after ART initiation, disease progression, and mortality among MSM in Jiangsu province compared with other persons living with HIV/AIDS. Median CD4 cell count among MSM at HIV diagnosis was 432 and decreased rapidly in 12 months to below the level of heterosexuals (slope: MSM -38.0, heterosexuals -15.5, injection drug users [IDU] -8.0, blood donors -10.5). Among those initiating ART, median CD4 cell count among MSM was 157, yet the increase in count was slower than for other groups (slope: MSM 26.9, heterosexuals 31.9, IDU 29.0, blood donors 35.0). Progression to AIDS was faster among MSM than heterosexuals and IDU. For the present, the mortality rate was lower for MSM compared with heterosexuals and blood donors; however, against a backdrop of more recent infection (ie, MSM had younger age, and 93.8 % were diagnosed after 2008), findings suggest a survival rate for MSM that will fall behind other groups. Improved medical and psychosocial supportive care is needed for this stigmatized population lest disparities become greater.

Abstract
Although the number of older people living with HIV/AIDS (PLWHA) has increased substantially, few studies have focused on older PLWHA in developing countries. Based on a sample of 866 rural PLWHA in Henan, Anhui and Yunnan provinces in China, this study compares the characteristics of PLWHA aged 50 or older (n=185) with younger PLWHA (n=681). Most of the older PLWHA were female (n=112), illiterate, married and at the clinical stage of HIV. Over 90% of older people with HIV/AIDS lived in Henan and Anhui provinces. The severe epidemic in Henan and Anhui provinces was caused by commercial blood and plasma donation. Older PLWHA were less educated, received less social support and were more likely to live alone than younger PLWHA. The results underline the importance of developing programs and policy initiatives targeted at older people infected with HIV/AIDS. The policy and program recommendations include using a gender sensitive strategy, designing specific AIDS education and prevention programs suitable for low-literacy older adults and social support interventions for older PLWHA.

Trends in high-risk sexual behaviors among general population groups in China: a systematic review. PLoS One 2013; 8:e79320. [PMID: 24236121 PMCID: PMC3827370 DOI: 10.1371/journal.pone.0079320] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2013] [Accepted: 09/20/2013] [Indexed: 11/23/2022] Open
Abstract
Background The objective of this review was to investigate whether Chinese population groups that do not belong to classical high risk groups show an increasing trend of engaging in high-risk sexual behaviors. Methods We systematically searched the English and Chinese literature on sexual risk behaviors published between January 1980 and March 2012 in PubMed and the China National Knowledge Infrastructure (CNKI). We included observational studies that focused on population groups other than commercial sex workers (CSWs) and their clients, and men who have sex with men (MSM) and quantitatively reported one of the following indicators of recent high-risk sexual behavior: premarital sex, commercial sex, multiple sex partners, condom use or sexually transmitted infections (STIs). We used generalized linear mixed model to examine the time trend in engaging in high-risk sexual behaviors. Results We included 174 observational studies involving 932,931 participants: 55 studies reported on floating populations, 73 on college students and 46 on other groups (i.e. out-of-school youth, rural residents, and subjects from gynecological or obstetric clinics and premarital check-up centers). From the generalized linear mixed model, no significant trends in engaging in high-risk sexual behaviors were identified in the three population groups. Discussion Sexual risk behaviors among certain general population groups have not increased substantially. These groups are therefore unlikely to incite a STI/HIV epidemic among the general Chinese population. Because the studied population groups are not necessarily representative of the general population, the outcomes found may not reflect those of the general population.

High prevalence of HIV, HCV and tuberculosis and associated risk behaviours among new entrants of methadone maintenance treatment clinics in Guangdong Province, China. PLoS One 2013; 8:e76931.

Abstract
Background Methadone maintenance treatment (MMT) has been available in Guangdong province, China since 2006. This study aims to estimate the prevalence levels of HIV, Hepatitis C (HCV), Tuberculosis (TB) and their co-infections and associated demographic and risk behaviours among MMT entrants. Method A total of 2296 drug users at the time of their MMT enrolment were recruited from four clinics during 2006-2011. Participants’ demographic characteristics, infection status and self-reported high-risk drug-use and sexual behaviours were surveyed. Log-linear contingency analysis was employed to investigate the demographic and behavioural differences between gender and drug-user type, while multivariate regression analysis was used to identify the associated factors of HIV, HCV and TB infections. Results Female drug users demonstrate significantly higher frequency of daily drug consumption (Log-linear contingency analysis, G2=10.86, p=0.013) and higher proportion of having had sex in the past three months (G2=30.22, p<0.001) than their male counterparts. Among injecting drug users, females also inject (χ2=16.15, p=0.001) and share syringes (χ2=13.24, p=0.004) more frequently than males. Prevalence of HIV, HCV and TB among MMT entrants are 6.3%, 78.7% and 4.4% respectively. Co-infections of HIV/HCV, HIV/TB, HCV/TB and HIV/HCV/TB reportedly infect 5.6%, 0.5%, 3.8% and 0.3% of study participants. Infection risks of HIV, HCV and TB are consistently associated with increasing length of drug use, injecting drugs, financial dependence and reduced sexual activities. Conclusion Injecting drug use is the major contributing factor in prevalence levels of HIV, HCV and TB among MMT entrants. Female drug users are more disadvantaged in their social status and risk-taking in their drug use behaviours than males.
