    BACKGROUND: Poor HIV testing uptake by MSM may be attributable to unique challenges that are localized in Southeast Asia.

    OBJECTIVE: To characterize MSM who never tested for HIV, to identify correlates of never testing, and to elucidate the perceived barriers to HIV testing.

    METHODS: The present study used data from the Asian Internet MSM Sex Survey (AIMSS) and restricted the analysis to 4,310 MSM from the ten member countries of the Association of South East Asian Nations (ASEAN).

    RESULTS: Among MSM participants from ASEAN in our sample, 1290 (29.9%) reported having never been tested for HIV, 471 (10.9%) tested for HIV more than 2 years ago, and 2186 (50.7%) reported their last test date was between 6 months and two years ago, with only 363 (8.4%) of these men having been tested in the past 6 months. In multivariable logistic regression, younger MSM (age 15-22 years old [AOR: 4.60, 95% CI: 3.04-6.96]), MSM with lower education (secondary school or lower [AOR: 1.37, 95% CI: 1.03-1.83]), MSM who identify as bisexual or heterosexual (compared to gay-identified) (AOR: 1.94, 95% CI: 1.60-2.35), and MSM who had never used a condom with male partners (AOR: 1.61, 95% CI: 1.32-1.97) had higher odds of never been HIV tested. Main reason for not being tested was a low risk perception of HIV exposure (n = 390, 30.2%).

    CONCLUSION: Current HIV prevention response must not leave MSM "in the dark," but instead meet them where they are by utilizing the Internet creatively through social media and smart phones. As ASEAN Economic Community (AEC) is quickly becoming a reality, so must there be an equally fast and united response to slowing down the HIV epidemics among MSM in ASEAN.

    The number of people worldwide living with human immunodeficiency virus/ acquired immunodeficiency virus (HIV/AIDS) is more than 40 million, among them 17.7 millions are women (UNAIDS/WHO, 2006) The latest report from the Eastern Mediterranean Region shows that at least one million people are infected with HIV; among them 30% are women. The great majority of reported cases in the Region are men. However, the ratio of men to women cases varies in different countries. It ranges between “9:1 (as for example in Egypt), to 2:1” (as in Morocco and some parts of Yemen). Due to religious, social and cultural values regarding female purity, women and girls living with HIV and AIDS are subjected to greater discrimination than men. WHO reports show that a large percentage of the infected women in Arab countries have contacted the infection from their husbands especially migrants and drug abusers. In Arab countries, studies conducted show that 86% of women choose not to disclose their status of infection for the fear of abandonment, rejection, discrimination, violence, upsetting family members, and accusations of infidelity from their partners, families, and communities. As a result, many women only seek help at the last minute when they are already been terminally ill. Violence against women and girls in its different forms increases women's vulnerability to HIV infection and undermines AIDS control efforts. The fear of violence prevents many women from accessing HIV information, from getting testing and seeking treatment. Stigma and discrimination may also prevent them from carrying out their normal life activities. When women are blamed, this can lead to heightened levels of sexual and domestic violence, abandonment by families and communities, forced abortion or sterilization, dismissal from employment and loss of livelihood opportunities. A study of AIDS-related discrimination in Arab region found that over ten percent of women had lost financial support from family members since being diagnosed as HIV positive. There is a great deal of evidence to establish the significant link between gender-based violence and rising rates of HIV infection among women and girls throughout the world. HIV-positive women must be supported to make their own reproductive choices about whether and/or when to have children. Promote male involvement in sexual and reproductive health programmes. Finally the stigma, discrimination and violations must be stopped.

    We prospectively evaluated the effects of pulsed magnetic stimulation (PMS) on sexual function of couples with stress urinary incontinence (SUI) partners. Female SUI subjects received 16 or 32 biweekly PMS sessions, depending on treatment response. Prior to, immediately after, and at 6-months posttreatment, couples completed the Golombok Rust Inventory of Sexual Satisfaction (GRISS) questionnaire. Fifty-three (80.3%) of 66 couples completed reassessments. Based on the overall GRISS score, there were significant improvements in sexual function in both female subjects (Mdiff -5.05, SE 1.34, p = 0.001) and their partners (Mdiff -3.42, SE 1.24, p = 0.026). Our findings suggest that PMS improved sexual function of SUI patients and their partners.

    The U.S. female criminal justice (CJ) population is rapidly growing, yet large-scale studies exploring gender-specific HIV risk behaviors in the CJ population are lacking. This analysis uses baseline data on adults with a CJ history from eight U.S. studies in an NIH-funded "Seek, Test, Treat, Retain" harmonization consortium. Data were collected using a standardized HIV risk behavior assessment tool and pooled across studies to describe participants' characteristics and risk behaviors. Multilevel mixed-effects logistic regression models were used to test for gender-based behavior differences. Among 784 HIV-positive (21.4% female) and 5521 HIV-negative (8.5% female) participants, HIV-positive women had higher odds than HIV-positive men of engaging in condomless sexual intercourse (AOR 1.84 [1.16-2.95]) with potentially sero-discordant partners (AOR 2.40 [1.41-4.09]) and of sharing injection equipment (AOR 3.36 [1.31-8.63]). HIV risk reduction interventions targeting CJ-involved women with HIV are urgently needed as this population may represent an under-recognized potential source of HIV transmission.

    Despite the growing HIV threat among injecting drug users (IDUs) in Malaysia, there is a dearth of information on their HIV risk behaviour. This study focused on identifying specific risk behaviours that distinguished HIV positive IDUs from those who were not. For the first time, data on IDUs not in treatment were obtained through a cross-sectional survey of 526 subjects recruited from five selected cities across peninsular Malaysia. A structured questionnaire and face-to-face interviews were utilised to collect detailed information on their drug use practices and sexual behaviours. On-site serological testing determined their HIV and hepatitis C status. The findings indicated that ethnic Malays, who are also Muslims, form the majority of IDUs not in treatment. Bivariate analysis identified six risk factors associated with HIV seropositivity: being 44 years or younger; not holding a regular job; initiating drug use at age 23 or younger; being a morphine user; sharing injecting equipment and having multiple-sex partners. However, only the last two remained significant in multivariate analysis. That sharing contaminated injecting equipment is a significant risk factor strongly justifies the widening of the pilot needle and syringe exchange programme initiated hesitantly in late 2005 as a reaction to the worsening HIV/AIDS situation. Condom use, though not independently significant, remains important because consistent and wider use could neutralise the second risk factor--having multiple-sex partners. The finding that injecting drug use is increasingly occurring in groups underscores the need for outreach programmes that emphasise safe injecting practices in group settings. In addition, counsellors should endeavour to convince drug users to enter treatment since being in treatment appears to reduce risk behaviours. Finally, conservative Muslim unease about harm reduction must be assuaged quickly since Malay Muslims form the majority of IDUs not in treatment.

    BACKGROUND: High prevalence of substance use among men who have sex with men (MSM) may drive the HIV epidemic in Malaysia but patterns of substance use among Malaysian MSM have not been examined. Our study investigated specific Malaysian MSM risk groups to determine the association between their substance use and sexual risk behaviors.
    METHODS: Data from Malaysian respondents (n=1235) in a large, multinational online survey of Asian MSM in 2010 were used to identify latent classes of substance use. Subsequent covariates were included in a joint model to predict class membership.
    RESULTS: The 3-class model was identified as the best fitting model, which included: (1) 'negligible substance use' for those reporting none or using any substance sparingly; (2) 'soft substance use' for those using poppers, ecstasy and drinking before sex; and (3) 'amphetamine-type stimulant (ATS) use' for those using stimulants (methamphetamine, ecstasy), erectile dysfunction drugs and recreational drug use before sex. Men in the 'ATS use' category were significantly less likely to not know their HIV status (AOR: 0.30, 95%CI: 0.14,0.66), more likely to have had more than 6 male sex partners (AOR: 4.83, 95% CI: 1.92-12.2), to have group sex (AOR:4.07, 95% CI: 2.31-7.15), to report inconsistent condom use (AOR:2.01, 95% CI: 1.12-3.60), to be HIV-infected (AOR:3.92, 95% CI: 1.63-8.42) and to have had any sexually transmitted infections (AOR:3.92, 95% CI:1.70, 9.08), compared to men in the 'negligible substance use' category.
    CONCLUSIONS: Our study identified subgroups of Malaysian MSM with distinct substance use patterns and HIV-related risk profiles, which provides implication for targeting HIV prevention in this subpopulation.

    BACKGROUND: Late presentation of human immunodeficiency virus (HIV) is associated with heterosexual transmission, particularly among heterosexual men in Asia. Although data on HIV/sexually transmitted infection (STI) testing behaviour is increasing, information is still lacking among heterosexual men who receive far lesser attention and are generally invisible in HIV/ STI prevention, particularly in the Asian urban setting. The aim of this study was to assess the prevalence of HIV/STI testing among heterosexual men patronising entertainment establishments (EEs) who engaged in casual or paid sex in Singapore, and the factors associated with this behaviour.

    METHODS: This was a cross-sectional survey involving 604 participants using time location sampling between March and May 2015. For multivariable analysis, we used a mixed effects Poisson regression model with backward stepwise approach to account for clustering by venue and to obtain the adjusted prevalence ratio (aPR) for the association of various factors with HIV/STI testing.

    RESULTS: Among 604 at-risk participants, only 163 (27.0%) had gone for HIV or STI testing in the past 6 months. Of this, 83.4% of them specifically underwent HIV testing. In multivariable analysis, HIV/STI testing increased with being non-Chinese (aPR 1.50; 95% CI: 1.08-2.06), having engaged in anal sex with casual or paid partner in the past 6 months (aPR 1.80; 95% CI: 1.27-2.57), number of partners in the past 6 months (aPR 1.03; 95% CI: 1.01-1.05) and HIV knowledge score (aPR 1.11; 95% CI: 1.05-1.16). Among those who reported non-consistent condom use with casual or paid partner, almost half of them (47.9%) perceived that they were at low risk for HIV/STI. Sigmatisation and discrimination was another common barrier for non-testing.

    CONCLUSIONS: Despite being at risk of HIV/STI, the low prevalence of testing coupled with a high prevalence of risky sexual behaviour among this group of heterosexual men in Singapore calls for a need for HIV/STI prevention interventions in the EE setting. Other than promoting testing and safer sex, the interventions should address the discordance between perceived risk and actual sexual behaviour, in addition to the stigma and discrimination associated with testing for this group.

    BACKGROUND: Sex workers face a disproportionate burden of human immunodeficiency virus (HIV) and sexually transmitted infections (STI) worldwide. For cisgender women sex workers (CWSW), global HIV prevalence is over 10%, whereas transgender women sex workers (TWSW) face an HIV burden of 19% to 27%.

    METHODS: We used respondent-driven sampling to recruit 492 sex workers, including CWSW (n = 299) and TWSW (n = 193) in Greater Kuala Lumpur, Malaysia. Participants completed an in-depth survey and were screened for HIV, syphilis, Chlamydia trachomatis, and Neisseria gonorrhoeae. Sample characteristics stratified by gender identity and interview site are presented. Bivariate analyses comparing CWSW and TWSW were conducted using independent samples t tests for continuous variables and χ tests for categorical variables.

    RESULTS: Pooled HIV prevalence was high (11.7%; 95% confidence interval [CI], 8.8-14.5), and was similar for CWSW (11.1%) and TWSW (12.4%). Rates of syphilis 25.5% (95% CI, 21.6-29.5), C. trachomatis (14.8%; 95% CI, 11.6-18.0) and N. gonorrhoeae (5.8%; 95% CI, 3.7-7.9) were also concerning. Both groups reported lifetime HIV testing (62.4%), but CWSW were less likely to have ever been HIV tested (54.5%) than TWSW (74.6%). Median time since last HIV test was 24 months. Previous screening for STI was low. Inconsistent condom use and drug use during sex work were not uncommon.

    CONCLUSIONS: High HIV and STI prevalence, coupled with infrequent HIV and STI screening, inconsistent condom use, and occupational drug use, underscore the need for expanded HIV and STI prevention, screening, and treatment efforts among CWSW and TWSW in Malaysia.

    Hepatitis C infection is a global public health problem. This study was designed to identify the risk factors associated with hepatitis C infection among adult patients in Kedah state, Malaysia. A matched, hospital-based, case-control study was conducted at a tertiary hospital. Cases were adult (aged ≥ 18 years) patients with positive serology test results for hepatitis C virus antibody and detectable hepatitis C virus RNA from January 2015 to December 2018, and controls were age-, sex- and ethnicity-matched patients who were not infected with hepatitis C virus. Self-administered questionnaires were used to collect data on demographic characteristics and previous exposure to selected risk factors among the study participants. Associations between hepatitis C and demographic and risk factors were assessed using univariable and multivariable logistic regression analyses. A total of 255 case-control patient pairs were enrolled. The multivariable analysis indicated that having a history of blood or blood product transfusion before 1992 (adjusted odds ratio [AOR] = 6.99, 95% confidence interval [CI]: 3.73-13.81), injection drug use (AOR = 6.60, 95% CI: 3.66-12.43), imprisonment (AOR = 4.58, 95% CI: 1.62-16.40), tattooing (AOR = 3.73, 95% CI: 1.37-12.00), having more than one sexual partner (AOR = 2.06, 95% CI: 1.16-3.69), piercing (AOR = 1.71, 95% CI: 1.04-2.80), and having only secondary education (AOR = 1.92, 95% CI: 1.06-3.57) were independently associated with hepatitis C. No associations were found between health care occupation, needle-prick injury, surgical procedures, haemodialysis, acupuncture, cupping, or contact sports and hepatitis C infection. These findings demonstrate that hepatitis C risk is multifactorial. Having a history of blood or blood product transfusion before 1992, injection drug use, imprisonment, tattooing, having more than one sexual partner, piercing, and having only secondary education were associated with increased odds of hepatitis C.

    BACKGROUND: Men who have sex with men (MSM) continue to be disproportionately affected by HIV in Malaysia. Recent success has been observed within demonstration projects examining the efficacy of HIV pre-exposure prophylaxis (PrEP), an antiretroviral -based medication taken by HIV-negative men to prevent sero-conversion. In order for such promising findings to be translated in real-world settings, it is important to understand the acceptability of PrEP, including perceived barriers to access or uptake.

    METHODS: As part of a larger mixed-methods study exploring acceptability and willingness to use PrEP among MSM in Malaysia, 19 men took part in audio-recorded focus group discussions hosted by a community-based HIV organization and facilitated by a trained researcher. Discussions focussed on awareness and potential information management, general perceptions of PrEP and potential motivations or barriers to the use of PrEP, including those at the personal, social, health system or structural level. Data were transcribed verbatim and underwent a detailed thematic analysis.

    RESULTS: Rather than perceiving PrEP as a replacement for condoms in terms of having safer sex, many participants viewed it as an additional layer protection, serving as a crucial barrier to infection on occasions where condom use was intended, but did not occur. It was also perceived as more valuable to "at-risk" men, such as those in HIV sero-discordant relationships or those with a higher number of sexual partners. Elements of discussion tended to suggest that some men taking PrEP may be subject to stigma from others, on the assumption they may be promiscuous or engage in high-risk sexual behaviours.

    CONCLUSIONS: This qualitative study indicates that, broadly speaking, PrEP may be acceptable to MSM in Malaysia. However, in order for its potential to be realized, and uptake achieved, educative interventions are required to inform the target population as to the efficacy and potential, positive impact of PrEP. Given concerns for how those taking it may be stigmatized, it is crucial that the use of PrEP is presented as a responsible course of action, and one of a range of strategies that men can use to keep themselves safe from HIV.

    OBJECTIVE: We examined willingness to use pre-exposure prophylaxis (PrEP) for HIV prevention among men who have sex with men (MSM) in Malaysia.

    METHODS: An online survey of 990 MSM was conducted between March and April 2016. Eligibility criteria included being biological male, Malaysian citizen, 18 years of age or above, identifying as MSM, and being HIV negative or unknown status. Participants' demographics, sexual and drug use behaviors, attitudes towards PrEP, and preferences regarding future access to PrEP were collected. Bivariate analysis and logistic regression were performed to determine factors associated with willingness to use PrEP.

    RESULTS: Fewer than half of participants (44%) knew about PrEP before completing the survey. Overall, 39% of the sample were willing to take PrEP. Multivariate logistic regression indicated that Malay men (AOR: 1.73, 95% CI:1.12, 2.70), having 2 or more male anal sex partners in the past 6 months (AOR: 1.98, 95% CI: 1.29, 3.05), previous knowledge of PrEP (AOR: 1.40, 95%CI: 1.06, 1.86), lack of confidence in practising safer sex (AOR: 1.36, 95% CI: 1.02, 1.81), and having ever paid for sex with a male partner (AOR: 1.39, 95% CI: 1.01, 1.91) were independently associated with greater willingness to use PrEP, while men who identified as heterosexual were less willing to use PrEP (AOR, 0.36, 95% CI: 0.13, 0.97). Majority of participants preferred to access PrEP at affordable cost below 100 Malaysian Ringgit (USD25) per month from community based organisations followed by private or government hospitals.

    CONCLUSIONS: Overall, MSM in Malaysia reported a relatively low level of willingness to use PrEP, although willingness was higher among those previously aware of PrEP. There is a need to provide PrEP at affordable cost, increase demand and awareness of PrEP, and to provide access to this preventative medication via diverse, integrated and tailored sexual health services.
