RESUMO
In China, female injection drug users who are also sex workers (IDUFSW) have a high prevalence of HIV and low prevalence of HIV testing. They are concerned about HIV infection and may be subjected to the risk of suicidal ideation if they become infected, due to stress and discrimination. During 2005-2006, we recruited 199 IDUFSW who self-reported negative/unknown HIV sero-status in Dazhou, Sichuan, China, to investigate the prevalence of and factors associated with suicidal ideation if they became HIV positive. Among the participants, 40.7% responded affirmatively to the question "Whether you would commit suicide if you were infected with HIV in the future?" In multivariate analyses, hatred toward oneself, perception of dying within 2-3 years, perceived nonavailability of HIV-related treatment, inability to cope with HIV-related trauma, and inclination to leave one's family if one contracted HIV were significant factors related to anticipated suicidal ideation under the hypothetical situation of HIV infection. The odds ratios (OR) ranged from 2.38 to 10.36 (p < .05). These findings can facilitate the planning of primary suicidal prevention services targeting high-risk, non-HIV-positive IDUFSW. Such programs may enhance psychosocial support, empowerment, cultivation of positive coping strategies, and perceived accessibility to treatment, and be integrated with HIV testing.

Both drug injection and sexual transmission are the primary drivers of the HIV epidemic in China. This study investigated the prevalence and associated factors of intention of consistent condom use during sexual intercourse with female regular partners (RP), non-regular partners (NRP) and sex workers (FSW) among male people who inject drugs (PWID)in China. A total of 529 male non-institutionalized PWID aged 18-45 years with negative/unknown HIV status were recruited by multiple methods in Dazhou and Hengyang, China. The constructs of the pre-intention phase of the Health Action Process Approach (HAPA) Model, including partner-specific HIV risk perception, condom use positive outcome expectancies, condom use negative outcome expectancies, and self-efficacy of condom use, were assessed. The prevalence of behavioral intention of consistent condom use with RP, NRP, and FSW was 32.1%, 49.1%, and 63.6%, respectively. In multivariate stepwise analysis, conditional risk perception of HIV transmission via unprotected sex with RP/NRP/FSW was associated with intention of consistent condom use with these types of female sex partners (multivariate odds ratio (ORm) = 3.25-7.06). Condom use negative outcome expectancies were associated with intention of consistent condom use with RP and NRP (ORm = 0.30-0.46), while condom use self-efficacy was associated with intention of consistent condom use with RP and FSW in the next six months (ORm = 2.24-3.81). Male PWID are at high risk of HIV transmission through sexual behaviors. The pre-intention phase of the HAPA model may be applied to plan interventions to increase behavioral intention of consistent condom use with various types of female partners. Such interventions are warranted.

Compulsivity is defined as "an insistent, repetitive, intrusive, and unwanted urge to perform specific acts often in ritualized or routinized fashions." Sexual compulsivity has been shown to be associated with some high risk sexual behaviors related to HIV and sexually transmitted infection (STI). In some Western countries, the 10-item Sexual Compulsivity Scale (SCS) has been developed to assess people's sexual compulsivity but no Chinese version has been validated. This study validated the Chinese version of the SCS and investigated its associations with specific sexual behaviors. In 2008, a random telephone survey was conducted in the sexually active male general population in Hong Kong, interviewing 1,048 participants. The Chinese version of the SCS was found to be internally consistent (Cronbach's α = 0.88 for the overall scale), with a mean total score of 20.7 (SD = 4.7). An exploratory factor analysis procedure extracted two factors that were named Controllability and Functional Consequences. Higher SCS scores were associated with multiple female sexual partnerships in the last 6 months, having had sex with either non-regular partner(s) or female sex worker(s) in the last 6 months, having contracted STI in the last 6 months, and inconsistent condom use with either non-regular partner(s) or female sex worker(s) in the last 6 months. The scale can be used to assess sexual compulsivity among sexually active Chinese men in Hong Kong. It can potentially be used in other Chinese communities. Further confirmatory studies are warranted.

This study investigated the associations between sexual dysfunction and unprotected anal intercourse among adult Chinese men who have sex with men; 519 participants who had had anal sex (past 12 months) were recruited from gay venues (Hong Kong and Shenzhen) and from the Internet (Hong Kong). Respectively, 48.9% and 59.6% (p< .05) of the Hong Kong and Shenzhen participants had had at least one type of sexual dysfunction for 3 consecutive months (past 12 months); the difference may be explained by differential income levels or other factors. After adjustment for significant background variables, three variables related to sexual dysfunction (premature ejaculation, erectile dysfunction, and experienced at least one sexual dysfunction) were significantly associated with unprotected anal intercourse in the Hong Kong (adjusted odds ratio = 1.65-2.80) and Shenzhen samples (adjusted odds ratio = 5.46-6.41). Anxiety about sex was significant only in the Shenzhen sample (adjusted odds ratio = 8.67). The associations may be results of coping toward sexual dysfunction. Sexual dysfunction is prevalent and may contribute to unprotected anal intercourse among men who have sex with men in China. Physiological damages of receptive anal sex may contribute to some types of sexual dysfunction. However, one limitation is that participants were not asked about insertion/receptive anal sex. HIV interventions targeting men who have sex with men in China need to take counseling related to sexual dysfunction into account.

OBJECTIVE: We investigated the prevalence and associated factors of men who have sex with men (MSM) and had never participated in Human Immunodeficiency Virus (HIV) voluntary counseling and testing (VCT) but intended to do so in the next six months. METHOD: An anonymous cross-sectional survey interviewed 577 MSM in Hong Kong, China, face-to-face or through an electronic questionnaire. RESULTS: We identified 245 MSM who had never participated in VCT (never-testers), among whom 12.7% intended to do so in the next six months. Factors associated positively with high behavioral intention were: 1) perceived necessity to participate in HIV test regularly (multivariate odds ratios (ORm)=4.54, 95% confidence interval (CI): 1.30-15.83), 2) perception that >20% of the local MSM had participated in VCT (ORm=17.86, 95% CI: 1.89-169.08) and 3) perceived higher chance to have sex with people living with HIV (PLWH) in the next six months (ORm=2.92, 95% CI: 1.08-7.93). Negatively associated factors were: local residency (ORm=0.06, 95% CI: 0.01-0.34) and perceived higher chance of having unprotected anal intercourse (UAI) in the next six months (ORm=0.27, 95% CI: 0.09-0.84). In addition, no interaction term between the independent variable and UAI status was found to be statistically significant. CONCLUSION: Many sampled never-testers had low intention to take up VCT and were in the pre-contemplation stage of the Transtheoretical Model. Stage-matched promotions are warranted.

Female condom is an effective means of HIV prevention. Monogamous female sexually transmitted infection (STI) patients are exposed indirectly to high risk of contracting HIV/STI via their sole male sex partners. There are few interventions to protect such women whilst female condom use is a potential means of self-protection. With informed consent, this cross-sectional study investigated the prevalence of awareness and acceptability of female condoms among 335 Chinese monogamous female STI patients attending a government STI clinic in Hong Kong. Among those who were aware of female condoms (66.9 % of the sample), 68.3 % were willing to use free female condoms. Awareness was associated with having the sex partner being a boyfriend (OR = 3.76, P < 0.001), knowledge about asymptomatic property of HIV (OR = 2.14, P = 0.006) and no immunity for STI (OR = 2.14, P = 0.011), experience of HIV antibody testing (OR = 2.21, P = 0.004) and unemployment (OR = 0.50, P = 0.011). Among those who had heard of female condoms, acceptability was associated with knowledge about possibility to contracting two STI concomitantly (OR = 2.26, P = 0.03) and perceived chance of contracting STI from the sex partner in the coming 6 months (OR = 2.27, P = 0.04). Awareness is relatively low but the prevalence of acceptability is encouraging. Female condoms have been underused and should be promoted among monogamous female STI patients as a means of empowerment as an option for sex protection.

In China, the HIV prevalence among men who have sex with men (MSM) has been increasing sharply. A total of 195 Hong Kong MSM having had sex with men in Shenzhen, a mainland China city separated from Hong Kong by a border, were recruited from some randomly selected gay venues in Shenzhen. Participants were face-to-face and anonymously interviewed. The results showed that in the last six months, respectively 62.1, 84.6, and 31.3 % of the participants from Hong Kong had had sex with commercial sex partners (CSP), non-regular partners (NRP) and regular partners (RP) in Shenzhen. The prevalence of unprotected anal intercourse (UAI) with these three types of sex partners was respectively 29.8, 27.9, and 78.7 %. Factors associated with UAI with any MSM in Shenzhen in the last six months included perceived chances of contracting HIV, perceived non-availability of condoms, giving money/gifts to Shenzhen MSM sex partners, and perception that MSM partners in Shenzhen would not always insist on condom use (multivariate OR = 2.9-13.90, p < 0.05), whilst factors of inverse associations included university education, having had sex with NRP but not with CSP and RP in Shenzhen and self-efficacy of insisting on condom use (multivariate OR = 0.04-0.22, p < 0.05). In sum, the prevalence of having multiple types of male sex partners and UAI was high. This was especially true when anal sex with RP was involved. Cross-border HIV prevention is greatly warranted. It should ensure condom availability and modify perceptions toward UAI.

HIV is a serious health threat among men who have sex with men (MSM). A 2-month pilot network-based peer intervention was conducted among Chinese MSM in Hong Kong. Eight MSM peer educators were randomized into the Intervention or the Control Groups and recruited 36 and 33 peers to join the program, respectively. The educators of the Intervention Group delivered standardized and theory-based preventive messages to their peers via daily social interactions. The Control Group received education materials. Baseline between-group differences were non-significant. At post-intervention, intervened participants were more likely than controlled participants to intend to use condoms consistently during anal sex with men in the next 6 months [94.4% versus 60.6%; Relative Risk (RR): 1.56 (95% Confidence Interval (CI): 1.17, 2.08)] and to perceive behavioral control over taking up voluntary HIV testing and counseling [97.2% versus 72.7%; RR: 1.34 (95% CI: 1.08, 1.66)]. Large scale randomized trials are warranted.

BACKGROUND: The impact of influenza on young children can be severe and even fatal. Influenza vaccination (IV) has been shown to be effective in reducing complications of influenza among children. This study investigated the prevalence and factors of IV among children aged 6-23 months in Hong Kong. METHODS: A sample of 401 Chinese parents of children aged 6-23 months were interviewed at local Maternal and Child Health Centers. Socio-demographic information, variables related to Health Belief Model, including perceptions about the child's chance of contracting influenza, perceived harm of influenza on children, perceived benefits and side-effects of IV, having received recommendations from health professionals to uptake IV, and IV behaviors of the children were measured. Multivariate analysis was used to examine factors associated with IV behaviors of children. RESULTS: Only 9% of the children had ever been vaccinated. Among those parents who had heard of IV (92.0%), substantial proportions perceived that IV could reduce the risk of influenza-induced complications (70.5%), hospitalization (70.5%) and death (65.9%). Relatively few of the participants believed that IV had no side effects (17.1%) and even less had been recommended by health care professionals to uptake IV (10.6%). Results from multivariate analysis showed that physician recommendations were associated with a higher likelihood for IV among younger children, whilst parental perceptions of the side effects of IV was associated with a lower likelihood for IV. CONCLUSION: The prevalence of IV among children aged 6-23 months in Hong Kong was very low. Promotion of IV with the component of physician recommendations and parents' knowledge about IV safety for this group is warranted.

INTRODUCTION: Monogamous female sexually transmitted infection (STI) patients are at high risk of recurrent STI, but there is no study investigating their risk behaviors. AIM: We investigated the prevalence of male condom use and associated factors among monogamous STI female patients. MAIN OUTCOME MEASURES: Independent variables included socio-demographic characteristics, STI history, nature of relationship, and cognitions (Health Belief Model). Dependent variables included the use of male condoms in the past two months and intention to use male condoms consistently in the future 6 months. METHODS: A cross-sectional survey using a structured questionnaire was conducted among STI female patients with only one male sex partner in the last 12 months and attended a major government STI clinic in Hong Kong. RESULTS: Among the 538 participants, 25.1% used condoms consistently (every time) during sex in the past 2 months, while 35.2% intended to do so in the next 6 months. A multiple stepwise logistic regression model identified three statistically significant factors associated with lower likelihoods of consistent condom use in the past 2 months: type of sole sex partner (cohabitant vs. husband: OR = 0.29, 95% CI = 0.12 to 0.70; regular boyfriend vs. husband: OR = 0.52, 95% CI = 0.30 to 0.91), being financially dependent (OR = 0.45, 95% CI = 0.27 to 0.75), and partner's dislike of condom use (OR = 0.23, 95% CI = 0.15 to 0.39). In a similar model, the same three factors were found to be significantly associated with the intention to use condoms consistently in the next 6 months. The low prevalence of intention to use condoms consistently in the future suggested that our study population might be victimized again. The impact of financially dependent relationships and men's dislike of using condoms on condom use may operate through imbalanced gender power. CONCLUSIONS: Interventions are greatly warranted and should increase risk awareness and empower this vulnerable population.

The HIV epidemic among men who have sex with men (MSM) in China is becoming very serious. Unprotected anal intercourse (UAI) among MSM during cross-boundary commercial sex spread HIV across geographic areas. This study interviewed 186 Chinese male sex workers (MSW) in Shenzhen, China, serving cross-boundary Hong Kong male clients; 49.5% had had UAI with their Hong Kong male clients (last six months) and 24.2% intended to do so (future six months). Multivariate analyses showed that perceived efficacy of condom use for HIV prevention, perceived prevalence of HIV among Hong Kong MSM (>4%), and perceived ability to convince Hong Kong male clients to use condoms during anal sex were associated with lower likelihoods of UAI with such clients (OR = 0.04-0.09); the reverse was true for those who left the decision of condom use to their Hong Kong male clients (OR = 6.44). Perceived condom efficacy, self-efficacy in protection against HIV infection, and perceived control over condom use were associated with an intention for UAI (OR = 0.06-80.44). Adjusting for background variables, the scales representing contextual (Clients Characteristics, Substance Use, or Environmental Influences) and affective factors (Fear of Diseases) were associated with UAI (adjusted OR = 0.44-32.61). Except the Fear of Diseases scale, other scales were associated with an intention for UAI (adjusted OR = 4.59-43.32). MSW are at high risk of HIV transmission. Various factors are associated with UAI with male cross-boundary clients; these factors and the context of sex work need to be considered when designing HIV prevention programs.

BACKGROUND: Human immunodeficiency virus (HIV)/sexually transmitted disease (STD)-related interventions rely on self-reported risk behavioral data, which are biased toward social desirability. It is warranted to develop methods for data triangulation. METHODS: Some questions on HIV/STD-related behaviors that were asked in 5 face-to-face (FTF) surveys were repeated at the end of the surveys, using the newly developed bean method (BM), which requested participants to transfer a bean of a particular color from a large jar to a smaller one, depending on whether the answer was affirmative (yellow, white, green, or red) or not (black); both jars contained 500 mixed-up colored beans. At the end of each day, the number of beans for each color was counted and was compared with the results of the FTF interviews. Participants were ensured that the researchers would not trace their responses. RESULTS: Among female sex workers who were noninjecting drug users, the BM as compared with the FTF interviews, reported higher prevalence of inconsistent condom use in the last 6 months, unprotected sex with the last client, and STD in the last 6 months. Among men who have sex with men in Hong Kong, the BM as compared to the FTF interviews, reported higher prevalence of unprotected sex with another man and having >3 sex partners in the last 12 months. No statistically significant between-method differences were reported among injecting drug users. CONCLUSIONS: Results of HIV/STD-related behaviors are dependent on mode of data collection. The simple BM can be used regularly to triangulate self-reported HIV-related behavioral data obtained from FTF interviews.

Behavioral surveillance data of 1422 sexually active female injecting drug users (IDU) in Sichuan China were analyzed. The prevalence of syringe-sharing was 43.5%. Respectively, 59.0%, 38.5% and 55.7% had regular, non-regular, and commercial sex-partner (RP, NRP, and CSP); 44.3% had multiple types of sex partners; 23.6 and 36.2% of those with RP had NRP and CSP. The prevalence of unprotected sex (last episode) with RP, NRP and CSP were respectively 75.4%, 50.7% and 39.3%; these three variables were associated with each other and with syringe sharing (univariate OR = 1.58-30.13). About 85% of the participants had attempted quitting drug use; the experience was not associated with condom use. HIV voluntary counseling and testing was associated with lower likelihood of unprotected sex with RP, NRP and CSP (multivariate OR= 0.44-0.60); the coverage was only 40.7%. Potential bridging of HIV transmission from IDU to non-IDU populations is a serious concern.

BACKGROUND: Existing surveillance systems for sexually transmitted diseases (STD) and reproductive tract infections (RTI) are important but often ineffective, as they tend to omit cases diagnosed by private-practice doctors METHODS: During a 15-day study period, 277 private-practice doctors and all public-practice doctors of all the eight local Social Hygiene Clinics (SHC) in Hong Kong filled out daily a standard log-form, recording the number of patients diagnosed with particular types of STD/RTI. Projections for all local private-practice and public-practice doctors were made by the stratification method. RESULTS: Data showed that 0.75% of private patients and 40.92% of public patients presented the listed STD/RTI syndromes. It is projected that 12,504 adults were diagnosed with such syndromes by all local private-practice (10,204) or public-practice doctors (2,300); 0.22% (male: 0.26%; female: 0.18%) of the local adult population would fall into this category. The ratio of STD/RTI cases, diagnosed by private-practice versus public-practice doctors, was 4:1. Of the participating private-practice doctors, 96% found the process easy to administer and 75% believed that it was feasible for such a STD/RTI surveillance system to be implemented annually. CONCLUSIONS: Surveillance of STD/RTI based only on data obtained from the public health system is inadequate. Data obtained from public-practice and private-practice doctors are very different and the majority of the patients presented their STD/RTI syndromes to private-practice doctors. The proposed, improved surveillance system is feasible and has the strengths of involving both private-practice and public-practice medical practitioners and being well accepted by private-practice doctors.

Mobile populations are vulnerable to contracting HIV. The present study aims to evaluate the relative efficacy of the voluntary counseling and testing plus information dissemination (VCT-ID) approach versus the information dissemination (ID) approach for promoting HIV preventive behaviors in a mobile population, cross-border truck drivers. A total of 301 adult male cross-border truck drivers who self-reported having had sex with female sex workers (FSW) or non-regular sex partners (NRPs) in mainland China in the last 12 months were recruited and randomized into the VCT-ID intervention group (Group I) or ID control group (Group C). Anonymous structured questionnaires, administered through a computer-assisted method, were used to collect data. At the follow-up survey (about 8-9 weeks since the baseline survey), Group I participants, as compared to Group C participants, were more likely to be consistent condom users when having sex with FSW (85.5% versus 68.5%, p<0.05) and with NRP (54.8% versus 36.4%, p<0.1), more knowledgeable about HIV, and were less likely to have contracted sexually transmitted diseases (STD) in the last two months. The VCT-ID approach is shown to be more efficacious than the ID approach in promoting safer sex and HIV-related knowledge among local cross-border truck drivers. Feasibility of providing voluntary counseling and testing (VCT) services at locations which are convenient to the target population is demonstrated. It also shows that VCT services can be used as a means of HIV prevention. The findings of this study resulted in up-scaled VCT services for the local target population.

BACKGROUND: During the SARS pandemic in Hong Kong, panic and worry were prevalent in the community and the general public avoided staying in public areas. Such avoidance behaviors could greatly impact daily routines of the community and the local economy. This study examined the prevalence of the avoidance behaviors (i.e. avoiding going out, visiting crowded places and visiting hospitals) and negative psychological responses of the general population in Hong Kong at the initial stage of the H1N1 epidemic. METHODS: A sample of 999 respondents was recruited in a population-based survey. Using random telephone numbers, respondents completed a structured questionnaire by telephone interviews at the 'pre-community spread phase' of the H1N1 epidemic in Hong Kong. RESULTS: This study found that 76.5% of the respondents currently avoided going out or visiting crowded places or hospitals, whilst 15% felt much worried about contracting H1N1 and 6% showed signs of emotional distress. Females, older respondents, those having unconfirmed beliefs about modes of transmissions, and those feeling worried and emotionally distressed due to H1N1 outbreak were more likely than others to adopt some avoidance behaviors. Those who perceived high severity and susceptibility of getting H1N1 and doubted the adequacy of governmental preparedness were more likely than others to feel emotionally distressed. CONCLUSIONS: The prevalence of avoidance behaviors was very high. Cognitions, including unconfirmed beliefs about modes of transmission, perceived severity and susceptibility were associated with some of the avoidance behaviors and emotional distress variables. Public health education should therefore provide clear messages to rectify relevant perceptions.

BACKGROUND: The objective of this study is to estimate the incidence of genital warts in Hong Kong and explore a way to establish a surveillance system for genital warts among the Hong Kong general population. METHODS: A total of 170 private doctors and all doctors working in the 5 local Social Hygiene Clinics (SHC) participated in this study. During the 14-day data collection period (January 5 through 18, 2009), the participating doctors filled out a log-form on a daily basis to record the number of patients with genital warts. The total number of new cases of genital warts presented to private and public doctors in Hong Kong was projected using the stratification sampling method. RESULTS: A total of 721 (0.94%) adults presented with genital warts to the participating doctors during the two-week study period, amongst them 73 (10.1%) were new cases. The projected number of new cases of genital warts among Hong Kong adults was 442 (297 male and 144 female) during the study period. The incidence of genital warts in Hong Kong was estimated to be 203.7 per 100,000 person-years (respectively 292.2 and 124.9 per 100,000 person-years for males and females). CONCLUSIONS: The incidence of genital warts is high among adults in Hong Kong. The study demonstrates the importance of collecting surveillance data from both private and public sectors.

BACKGROUND: Increasingly more men who have sex with men (MSM) are using the internet to seek sex partners, and many HIV-related studies targeting MSM collect data from gay venues in order to inform the design of prevention programs. However, internet-based MSM may have different HIV risk behaviors and associated factors from those attending venues. This study examined differences in risk behaviors and socio-cultural profiles between MSM recruited from venues (e.g., gay bars/saunas) and from the internet respectively. METHODS: An anonymous cross-sectional survey was conducted. A total of 566 Chinese MSM (340 recruited from gay-venues and 226 recruited from the internet) who self-reported having had anal or oral sex with another man in the last 12 months completed a structured questionnaire. RESULTS: Internet-based MSM were more likely than venue-based MSM to have engaged in unprotected anal intercourse (53.3% vs. 33.8%) or commercial sex (as clients: 12.8% vs. 5.3%; as sex workers: 6.2% vs. 1.5%), to have sought MSM partners from the internet (51.3% vs. 20.9%), and to have contracted sexually transmitted diseases (STD) in the last 12 months (4.4% vs. 0.3%). On the other hand, internet-based MSM were less likely to have multiple sex partners (58.4% vs. 75.6%) and to have used psychoactive substances (7.1% vs. 15.6%) or drunk alcohol before sex (8.8% vs. 16.2%). Moreover, internet-based MSM reported poor acceptance of their own sexual orientation, felt more discriminated against, and received less social support than venue-recruited MSM. CONCLUSIONS: Significant differences were observed between the two groups of MSM. Segmentation and targeted interventions are recommended when designing preventive interventions.

Male sex workers serving Hong Kong male clients in Shenzhen were surveyed (n = 199); 98.9% had been in Shenzhen for < or =3 years; 83.4% served local male clients; 82.8% had no family members/relatives in Shenzhen; 58.3% depended exclusively on sex work; 73% were bothered by one's sex work; and 81.7% found financial support unavailable when needed. About 29.1% had had unprotected anal intercourse (UAI) with Hong Kong male clients in the last month. UAI behavior was associated with exposure to HIV prevention services (OR = 0.08) and poor social support, being bothered by the sex work, substance use, and type of sex work venue (OR = 2.92-5.96).

INTRODUCTION: Limited data are available on sexual dysfunction (SD) in men who have sex with men (MSM) population. AIMS: The study investigates the prevalence and associated sociocultural factors of SD in MSM. METHODS: With an informed consent, 324 MSM respondents were interviewed by trained peer workers in certain gay venues, and another 87 MSM self-administered the same questionnaire via a gay website. MAIN OUTCOME MEASURES: Self-reported pain during intercourse, premature ejaculation, anxiety about sex, erectile dysfunction, no pleasure from sex, no orgasm, and hypoactive sexual desire were evaluated. RESULTS: Of all respondents, 42.5% had at least one of the seven studied SD for at least three consecutive months in the last 12 months (pain during sex, 13.8%; premature ejaculation, 10.4%; anxiety, 18.7%; erectile problems, 6.3%; no pleasure, 13.8%; no orgasm, 5.6%; hypoactive sexual desire, 8.3%), whereas 11.4% were dissatisfied with their sexual life. Except for erectile dysfunction, age had no significant effects on individual SD. The results of the multivariate analyses show that unemployment, venue of recruitment, substance use, number of HIV-related behaviors practiced, unprotected anal sex, self-perceived discrimination against MSM, self-identity of sexual orientation, experience of being discriminated because of one's MSM status, uneasy or shame feeling about one's sexual orientation/status, and the count variable of social support received regarding one's MSM status were associated with SD (multivariate OR=1.68-5.57), whereas having no or few MSM friends and exposure to HIV-related education were associated with lower chances of having some SD problems (multivariate OR=0.16-0.46). Only associations with P<0.05 were considered statistically significant. CONCLUSIONS: The prevalence of SD among MSM in Hong Kong is relatively high. SD in this group is associated with HIV-related behaviors as well as sociocultural factors related to social support and acceptance of one's MSM status. A more supportive environment is essential for the promotion of sexual health in MSM.
