A study of the STD/AIDS related attitudes and behaviors of men who have sex with men in Hong Kong

A random population based study was carried out to understand HIV-related attitudes and behaviors and self-reported sexually transmitted diseases (STDs) among men who have had sex with men (MSM) in Hong Kong. A special computerized telephone survey method was used and 85 MSM were identified (from a total sample of 2,074 men), 47.1% of whom had at least one male sex partner in the past 6 months. Among these 85 MSM, 29.4% had multiple partners and 37.5% had had anal sex in the last 6 months (67% of them were inconsistent condom users). MSM were more likely to have contracted at least one STD in the last 6 months (10.6%) and were less likely to perceive susceptibility for contracting HIV (62.4%) than those other respondents who visited a female sex worker (FSW) in the past 6 months (4.3% and 43%, respectively). About 45% of the MSM did not perceive condom use to be efficacious for HIV prevention (vs. 30% for male clients of FSW). The study is limited by its small number; however, it suggests that MSM in Hong Kong may be at high risk of contracting HIV. Prevention programs should attempt to change attitudes (e.g., perceived efficacy of condom use, perceived susceptibility, awareness of risk involved, etc.) as well as behaviors. The feasibility for establishing a behavioral surveillance system for this population was demonstrated.     

Prevalence of induced abortion and associated factors among Chinese female sex workers in Hong Kong

In this study, we interviewed 293 Chinese female sex workers (FSW) in Hong Kong of them, 55.6% of had experienced induced abortion 52.0% of which were accomplished in registered clinics. Those who were older, married, with frequent insomnia, did not use condom in the last episode of serving a client, and would agree not to use condom if paid more, were more likely than others to have had induced abortion (multivariate OR = 2.34 to 3.64). Those who were younger, had harmed herself, and drank at least 5 cans of beer per day (OR = 0.36 to 3.02) were more likely than others to have the induced abortion performed via improper means.     

Sexual Practices and Psychosocial Correlates of Current Condom Use Among Chinese Gay Men in Hong Kong

This study examined sexual practices, condom use, and psychosocial correlates of condom use in a convenience sample of 187 Chinese gay men in Hong Kong. Among those who were sexually active and answered the item on condom use (n = 164), 22% never used condoms, 39% were inconsistent condom users, and 39% used condoms every time they engaged in sexual activities in the past 6 months. Compared to inconsistent and noncondom users, consistent condom users had more positive feelings toward condom use, perceived greater vulnerability to STD/AIDS infections, showed greater self-acceptance and disclosure of their homosexual sexual orientation, were more involved with local gay communities, endorsed more favorable attitudes toward coming out, and had a lower level of perceived discrimination because of their homosexual sexual orientation. The two groups did not differ significantly on perceived partner reaction to condom use. Results of a logistic regression analysis showed that positive feelings toward condom use were the most salient correlate of consistent condom use.     

贵州省艾滋病高流行区汉族与少数民族女性性服务者艾滋病流行病学研究

目的了解贵州省铜仁市汉族与少数民族商业女性性服务者（FSW）艾滋病相关知信行及艾滋病病毒（HIV）感染率。方法对246名汉族和173名少数民族FSW开展横断面匿名问卷调查及HIV抗体检测。结果汉族与少数民族FSW在年龄、工作场所、婚姻状况、月收入等方面差异无统计学意义,但汉族FSW中外县市户籍者比例较少数民族者高,而少数民族FSW的文化程度较汉族者低。FSW均具备一定的艾滋病知识,但少数民族FSW的艾滋病知晓率较汉族者低。研究对象最近一次及最近一个月商业性行为时安全套使用率分别为95%和87.5%,而最近一次及最近一个月与固定性伴性行为时安全套使用率分别为70.3%及56.7%,少数民族FSW与汉族FSW安全套使用率差异均无统计学意义。少数民族FSW接受艾滋病咨询及性病诊疗服务方面的比例低于汉族FSW。未发现HIV感染者。结论贵州省铜仁市各民族FSW中商业性行为中安全套使用率高,HIV流行率低,但仍需加强针对该人群的艾滋病宣传教育和行为干预,尤其要重点关注少数民族FSW。     

Inconsistent condom use among socially excluded heroin users

The study focused in sexual behaviour among socially excluded heroin users, identifying factors associated with inconsistent condom use. Data was collected in the cities of Granada and Seville between July and October 2000, through a structured questionnaire, to 391 participants. Twenty two and 15% of participants have made consistent use of condoms in vaginal sex in the last year with occasional and regular partners respectively. There is a greater likelihood of inconsistent condom use with occasional partners among users who had had oral sex, and who does not know if their partner(s) inject or injected drugs. For regular partners those who have an injecting partner and do not speak with their sexual partners about AIDS have a higher probability to do not use always a condom. For both groups, when always the partner is who propose the use of condoms (when used) and not themselves, the risk not to use it is near 4 times more than when themselves propose to use it. Speaking about condoms and AIDS with mate, partners and family, and learning to negotiate the use of condoms seems to be the most important strategies to be approached for this sample, from the social and health care system in order to promote a protected sex.     

Between ‘0’ and ‘1’: safer sex and condom use among young gay men in Hong Kong

Young men who have sex with men are becoming the most at-risk subgroup for HIV incidence in Hong Kong. To understand how young gay men in Hong Kong interpret and implement safer sex and condom use, focus-group discussions and individual in-depth interviews were held. The 74 participants were nearly all ethnic Chinese gay men aged between 18 and 25 years. Findings indicate that the challenge for health intervention lies in young gay men’s inconsistent condom use despite their high level of HIV-related knowledge. Participants described using condoms, testing for HIV and abstaining from anal sex as measures undertaken to prevent HIV infection. However, sociocultural norms and expectations pertaining to ‘0’ (docile, bottom) and ‘1’ (assertive, top) roles and trust between partners complicate the consistent implementation of risk-reduction measures. Influenced by heteronormative and romantic beliefs, sexual behaviours such as condomless anal sex and internal ejaculation hold symbolic meanings – exclusivity, commitment, intimacy, possession – for young gay men in Hong Kong, which override health concerns. These findings support more empowerment-driven HIV programming for young gay men.     

Cross-boundary Substance Uses Among Hong Kong Chinese Young Adults

The study documents the characteristics of Hong Kong residents who used substances in mainland China. Characteristics of such users were compared with those using substances elsewhere. A cross-sectional survey was used. Data analyses were stratified by gender, and multivariate analyses were performed. Respondents, Hong Kong adults aged 18–30 (n = 6,528), were interviewed using a mixed interviewer and computerized mobile phone method, at the Hong Kong-mainland China boundary. Cross-border substance users and other types of substance users had characteristics that were quite different (e.g., education level, perceived harmfulness of substance use in general, having friends who frequently used substances in mainland China). Cross-boundary substance users also found it easier to obtain substances in mainland China than in Hong Kong (males: 60.5%, females: 39.6%) and perceived no chance of being arrested in mainland China because of substance use (men: 28.8%, women: 24.5%). They tended to use substances in discos/rave parties together with friends (men: 77%, women: 81%), and substances were often obtained for free (men: 63.2%, women: 78%). Ecstasy and ketamine were often used (men: 86.5% & 79.4%, women: 81% & 70.2%), and multiple uses of different substances were common (men: 81.3%, women: 68.6%). Lower price, peer influence, and better availability were reasons behind cross-boundary substance use behaviors. Cross-boundary substance users have specific characteristics. Prevention policies should take these characteristics into account. Regional collaborations are highly warranted.     

Methamphetamine Use,Attitudes About Condoms,and Sexual Risk Behavior Among HIV-Positive Men Who Have Sex with Men

This study examined attitudes about condoms as a moderator of the relationship between methamphetamine use and sexual risk behavior in a sample of 297 HIV-positive, methamphetamine-using men who have sex with men (MSM). To test for a moderating effect of attitudes towards condoms, an interaction term was included in multiple regression analysis along with age, income, negative condom attitudes, frequency of methamphetamine use, and Beck depression score. A post hoc analysis was conducted to determine the relations between methamphetamine use and unprotected sex for persons with more vs. less negative attitudes toward condoms. These analyses indicated that when individuals had more negative attitudes toward condoms, the relation between methamphetamine frequency and unprotected sex was significant, while among participants with less negative attitudes toward condoms, no significant association was found. Addressing methamphetamine-using MSM’s attitudes about condoms can serve as a form of harm reduction for those who are not yet ready or willing to discontinue methamphetamine use.     

暗娼与性伴之间安全套协商使用情况分析

目的 了解暗娼与嫖客或固定性伴之间安全套协商和使用情况，为暗娼的艾滋病综合干预措施的制定提供参考依据。方法 采用横断面调查，于2018年4－6月在云南省红河哈尼族彝族自治州蒙自市、建水县，依托娱乐服务场所招募≥16岁暗娼，估算样本量需476人，问卷调查收集其人口学特征、安全套协商及使用情况信息。采用logistic回归模型分析暗娼与不愿使用安全套的嫖客协商后安全套使用的影响因素。结果 共调查暗娼852人，年龄（24.29±8.44）岁。最近1个月性行为，有58.6%（499/852）的暗娼每次都要求嫖客使用安全套但嫖客不愿使用，协商后有88.4%（441/499）的暗娼每次与嫖客都使用安全套。有14.4%（99/687）的暗娼每次都要求固定性伴使用安全套，但固定性伴不愿使用，经协商后，54.5%（54/99）暗娼与固定性伴每次都使用安全套。最近1个月，暗娼说服不愿使用安全套的嫖客时，53.3%（266/499）的采用“强制要求”策略，19.4%（97/499）的采用“风险说服”策略，23.1%（115/499）的采用“强制要求及风险说服”策略，4.2%（21/499）的采用其他策略协商。4.4%（22/499）的暗娼感觉说服嫖客使用安全套困难。多因素logistic回归分析结果显示，和感觉说服嫖客使用安全套困难的暗娼相比，难度适中（OR=4.00，95% CI：1.55～10.32）、容易（OR=30.17，95% CI：3.22～282.44）的暗娼更容易成功协商嫖客每次都使用安全套。和采用其他策略与嫖客协商使用安全套的暗娼相比，采用“强制要求”策略者（OR=4.44，95% CI：1.41～14.01）、采用“强制要求及风险说服”策略者（OR=5.52，95% CI：1.55～19.73）更容易成功协商嫖客每次都使用安全套。结论 通过安全套协商策略，可促使不愿使用安全套的嫖客使用安全套。采用“强制要求”策略更容易成功协商嫖客每次都使用安全套，结合“风险说服”策略更有利于成功协商。

Female condom use among women at high risk of sexually transmitted disease

CONTEXT: Whereas the female condom has been evaluated in many hypothetical acceptability or short-term use studies, there is little information about its suitability for the prevention of sexually transmitted diseases (STDs) or HIV over extended periods of time. METHODOLOGY: As part of a six-month prospective follow-up study of 1,159 STD clinic patients, clients were interviewed during their initial visit, exposed to a behavioral intervention promoting condoms, given a physical examination and provided with instructions on completing a sexual diary. Potential predictors of trying the female condom were evaluated using logistic regression, and three condom-use groups (exclusive users of female condoms, exclusive users of male condoms and users of both types of condoms) were compared using multinomial regression. RESULTS: Among 895 women who reported having engaged in vaginal intercourse during the study period, one-half had sex with only one partner, while one-quarter each had two partners or three or more partners. A total of 731 women reported using the female condom at least once during the follow-up period--85% during the first month of follow-up. Multiple logistic regression analyses indicated that employed women and those with a regular sexual partner at baseline were significantly more likely to try the female condom. By the end of the follow-up period, 8% of participants had used the female condom exclusively, 15% had used the male condom exclusively, 73% had used both types of condom and 3% had used no condoms. Twenty percent of women who tried the female condom used it only once and 13% used it twice, while 20% used 5-9 female condoms and 32% used 10 or more. Consistent condom users (N=309) were predominantly users of both types of condom (75%), and were less often exclusive users of the male condom (18%) or the female condom (7%). According to a multivariate analysis, women who used the female condom exclusively or who mixed condom types were more likely to be black, were more likely to be employed and were more likely to have a regular partner than were users of the male condom. CONCLUSIONS: Women at risk of STDs find the female condom acceptable and will try it, and some use it consistently. Mixing use of female condoms and male condoms may facilitate consistent condom use. The female condom may improve an individual's options for risk reduction and help reduce the spread of STDs.     

Changes in sexual behavior and condom use among teenaged males: 1988 to 1995.

OBJECTIVES: This study examines shifts in sexual experience and condom use among US teenaged males. METHODS: Results from the 1988 and 1995 National Surveys of Adolescent Males were compared. RESULTS: The proportion of never-married 15- to 19-year-old males who had had sex with a female declined from 60% to 55% (P = .06). The share of those sexually active using a condom at last intercourse rose from 57% to 67% (P < .01). Overall, the proportion of males who had sex without condoms last year declined from 37% to 27% (P < .001). CONCLUSIONS: Although protective behaviors among teenagers have increased, significant proportions of teenagers--especially Black and Hispanic males--remain unprotected.     

Everywhere you go, everyone is saying condom, condom. But are they being used consistently? Reflections of South African male students about male and female condom use

Young men in South Africa can play a critical role in preventing new human immunodeficiency virus (HIV) infections, yet are seldom targeted for HIV prevention. While reported condom use at last sex has increased considerably among young people, consistent condom use remains a challenge. In this study, 74 male higher education students gave their perspectives on male and female condoms in 10 focus group discussions. All believed that condoms should be used when wanting to prevent conception and protect against HIV, although many indicated that consistent condom use was seldom attained, if at all. Three possible situations for not using condoms were noted: (i) when sex happens in the heat of the moment and condoms are unavailable, (ii) when sexual partnerships have matured and (iii) when female partners implicitly accept unprotected sex. Men viewed it as their responsibility to have male condoms available, but attitudes about whose decision it was to initiate condom use were mixed. Almost all sexually active men had male condom experience; however, very few had used female condoms. Prevention initiatives should challenge traditional gendered norms that underpin poor condom uptake and continued use and build on the apparent shifts in these norms that are allowing women greater sexual agency.

Depressive symptoms and condom use with clients among female sex workers in China

This study examines the association between depressive symptoms and condom use with clients among 278 female sex workers (FSW) in Guangxi, China. About 62% of these FSW had a high level of depressive symptoms (CES-D total score >or=16). Multiple logistic regression analyses indicated that FSW with high level of depressive symptoms were less likely to use condoms consistently (aOR = 0.50, 95% CI: 0.28-0.89) or use condoms properly (aOR = 0.44, 95% CI: 0.20-0.99). The findings suggested that HIV prevention programs targeted at FSW should take into consideration the level of depression they experience.     

北京市男男性行为者HIV新发感染率与高危行为及接受暴露前后预防用药服务情况调查

目的 了解北京市MSM的HIV新发感染率与高危行为及接受暴露前后预防（PrEP/PEP）用药服务情况。方法 采用Epi Info7.0软件计算参加横断面调查和队列调查样本量分别为1 227人和207人年。采用方便抽样法通过手机微信公众号招募MSM参加自填式网络问卷调查，收集其社会人口学、高危行为及接受PrEP/PEP用药服务利用情况，MSM自行采集干血斑样本邮寄到指定实验室进行HIV核酸检测。建立HIV核酸阴性受检者开放式队列，随访观察至研究终点。采用非条件logistic回归分析MSM最近1个月无保护肛交行为、最近1个月同性多性伴的影响因素。结果 共招募MSM 1 147人，其中HIV核酸阴性者956人观察236人年。HIV新发感染率为1.3/100人年（3/236）。最近1个月肛交和口交每次都使用安全套者分别占50.7%（238/469）和4.9%（23/469）。最近1个月与HIV感染者发生性行为的比例为5.9%（43/723）。分别有9.8%（103/1 049）和8.7%（91/1 049）的研究对象曾接受PrEP/PEP用药服务。PrEP/PEP用药期间发生性行为每次使用安全套的比例分别为34.3%（24/70）和72.2%（39/54）。多因素logistic回归分析结果显示，接受PrEP/PEP用药服务者的最近1个月发生无保护肛交行为和有同性多性伴的可能性均较高（aOR=3.16，95%CI：1.45~7.18；aOR=2.64，95%CI：1.19~6.30）；最近1个月使用毒品或Rush Popper者的最近1个月发生无保护肛交行为和有同性多性伴的可能性均较高（aOR=2.34，95%CI：1.67~3.30；aOR=2.42，95%CI：1.76~3.33）。结论 应在MSM中倡导坚持使用安全套及开展常见滥用药物危害的健康教育。在PrEP/PEP用药服务咨询中，需提示MSM坚持使用安全套的重要性。     

Prevalence and correlates of sexual risk among male and female sex workers in Tijuana, Mexico

We investigated prevalence and correlates of sexual risk behaviours among male and female sex workers in Tijuana, Mexico, the busiest border crossing area on the US - Mexico border, analysing survey data from a purposive, cross-sectional sample of male and female sex workers who worked in a range of indoor and outdoor settings. Logistic regression was used to determine factors that were associated with sexual risk-taking, defined as failing to use a condom with last client. In bivariate regression models, gender, work setting (e.g., indoor vs. outdoor), poverty, engaging in survival sex, marital status and perceived drug addiction were correlated with sexual risk. When controlling for work location, housing insecurity, poverty, survival sex, marital status and perceived drug addiction, male sex workers were still 10 times more likely than female sex workers (FSW) to engage in sex without a condom during their last encounter with a client. And, although FSW were significantly more likely than males to have used a condom with a client, they were significantly less likely than males to have used a condom with their regular partner. Future research should further examine how gender shapes sexual risk activities in both commercial and non-commercial relationships.

Sexualized Drug Use Among Female Sex Workers from Eight Cities in China: A Cross-Sectional Study

There is a rich literature on sexualized drug use (i.e., drug use before or during sex) for men who have sex with men but less data from female sex workers (FSW), particularly from low- and middle-income countries. We describe the sexual and reproductive health outcomes in FSW reporting sexualized drug use. In 2019, we conducted a cross-sectional study in eight cities from seven provinces in China. We recruited FSW through community organizations working with sex workers and included those aged 18 years or above, exchanged sex at least once for money or goods in the past three months, and had traded sex for longer than a year. Multivariable logistic regression models were used. In total, 650 women participated: average age was 38.8 years (SD 10.2), 57.1% reported a monthly income over 5000 RMB ($USD 707), and 12.8% completed high school or above. Among participants, 65 (10.0%, 95% confidence interval (CI) 7.8–12.6) reported a history of sexualized drug use. Compared to FSW who never reported a history of sexualized drug use, FSW who reported a history of sexualized drug use had greater odds of working for a manager compared to being self-employed (adjusted odds ratio (AOR) 4.04, 95% CI 2.12–7.69), work in a sauna (AOR 2.43, 95% CI 1.09–5.41), charging a higher price for vaginal sex (AOR 2.15, 95% CI 1.14–4.06), and ever diagnosed with STIs (AOR 4.51, 95% CI 2.61–7.80). One in ten FSW reported sexualized drug use. Although they had similar risk profiles in terms of consistency of condom use and reproductive health outcomes, these women were more likely to report past STIs than those who reported no sexualized drug use. Health workers who work with substance users should devote attention to the sexual practices of their clients to make sure that they have safer sex.
