Background AIDS-related stigma and mental disorders are the most common conditions in people living with HIV (PLHIV). We therefore conducted this study to examine the association of AIDS-related stigma and discrimination with mental disorders among PLHIV in Cambodia. Methods A two-stage cluster sampling method was used to select 1,003 adult PLHIV from six provinces. The People Living with HIV Stigma Index was used to measure stigma and discrimination, and a short version of general health questionnaire (GHQ-12) was used to measure mental disorders. Multivariate logistic regression analysis was conducted. Results The reported experiences of discrimination in communities in the past 12 months ranged from 0.8% for reports of being denied health services to 42.3% for being aware of being gossiped about. Internal stigma was also common ranging from 2.8% for avoiding going to a local clinic and/or hospital to 59.6% for deciding not to have (more) children. The proportions of PLHIV who reported fear of stigma and discrimination ranged from 13.9% for fear of being physically assaulted to 34.5% for fear of being gossiped about. The mean score of GHQ-12 was 3.2 (SD = 2.4). After controlling for several potential confounders, higher levels of mental disorders (GHQ-12≥ 4) remained significantly associated with higher levels of experiences of stigma and discrimination in family and communities (AOR = 1.9, 95% CI = 1.4–2.6), higher levels of internal stigma (AOR = 1.7, 95% CI = 1.2–2.3), and higher levels of fear of stigma and discrimination in family and communities (AOR = 1.5, 95% CI = 1.1–2.2). Conclusions AIDS-related stigma and discrimination among PLHIV in Cambodia are common and may have potential impacts on their mental health conditions. These findings indicate a need for community-based interventions to reduce stigma and discrimination in the general public and to help PLHIV to cope with this situation.

Background In Cambodia, HIV prevalence is high while HIV testing rates remain low among transgender women (TG women), men who have sex with men (MSM), and female entertainment workers (FEW). Introducing self-testing for HIV to these key populations (KPs) could potentially overcome the under-diagnosis of HIV and significantly increase testing rates and receipt of the results, and thus could decrease transmission. Therefore, this study aimed to determine the acceptability of HIV self-testing (HIVST) among these three categories of KPs. Methods This study was conducted through focus group discussions (FGDs) with TG women, MSM, and FEW in Phnom Penh city, Kampong Cham, Battambang, and Siem Reap provinces of Cambodia. Convenience sampling was used to recruit the participants. Two FGDs (six participants in each FGD) were conducted in each target group in each study site, totaling 24 FGDs (144 participants). Thematic analysis was performed to identify common or divergent patterns across the target groups. Results Almost all participants among the three groups (TG women, MSM, and FEW) had not heard about HIVST, but all of them expressed willingness to try it. They perceived HIVST as confidential, convenient, time-saving, and high-tech. Barriers to obtaining HIVST included cost, access, administration technique, embarrassment, and fear of pain. The majority preferred counseling before and after testing. Conclusions Participants showed high willingness to use and acceptability of HIVST due to its confidentiality/privacy and convenience even if it is not linked to a confirmatory test or care and treatment. Notwithstanding, to increase HIVST, the target groups would need affordable self-test kits, education about how to perform HIVST and read results, assurance about accuracy and reliability of HIVST, and provision of post-test counseling and facilitation of linkage to care and treatment.

Background Compared to the general population, men who have sex with men (MSM) are at greater risk for HIV and less understood due to their more hidden and stigmatized nature. Moreover, the discrepancy in findings in the literature merits further investigations in MSM populations from different cultures and settings. We therefore conducted this study to explore factors associated with inconsistent condom use among high-risk MSM in Cambodia. Methods This cross-sectional study was conducted in 2014 among 367 MSM randomly selected from Battembang and Siem Reap using a two-stage cluster sampling method. A structured questionnaire was used for face-to-face interviews to collect information on characteristics of respondents, HIV testing history, self-perception of HIV risk, substance use, sexual behaviors, mental disorders, and HIV knowledge. Multivariable logistic regression analysis was performed to identify factors independently associated with inconsistent condom use. Results On average, 62.3% of respondents reported that they always used condoms over the past three months. The rates varied with types of sexual partners; the proportion of respondents who reported always using condoms was 55.1%, 64.2%, 75.9%, 73.0%, 78.1%, and 70.3%, for sexual partners who were girlfriends, boyfriends, female sex workers, male sex workers, female clients, or male clients, respectively. After adjustment, inconsistent condom use was significantly associated with age of ≥25 (AOR = 1.77, 95% CI = 1.09–2.86), self-rated quality of life as good or very good (AOR = 4.37, 95% CI = 1.79–5.67), self-perception of higher HIV risk compared to the general population (AOR = 2.37, 95% CI = 1.35–4.17), illicit drug use in the past three months (AOR = 5.76, 95% CI = 1.65–10.09), and reported consistent lubricant use when selling anal sex to men in the past three months (AOR = 2.85, 95% CI = 1.07–8.12). Conclusions We found risky sexual behaviors to be considerably high among MSM in this study, especially among those who used illicit drugs or were older than 25. HIV education and social marketing should be expanded and specifically designed for MSM to better educate on the increased risk of HIV with unprotected anal sex and illicit drug use as risk factors, and the importance of the use of both condoms and lubricant during anal intercourse.

Objective To explore risk factors associated with induced abortion among sexually active female entertainment workers (FEWs) in Cambodia. Design Cross-sectional study. Setting Phnom Penh and Siem Reap, Cambodia. Participants This study included 556 FEWs aged 18–47 years randomly selected from entertainment establishments in the two cities in 2014 using a two-stage cluster sampling method. Data were collected through face-to-face interviews using a structured questionnaire. Primary outcome measure History of induced abortion during the time working as a FEW. Results Of the total sample, 45.6% reported currently using a contraceptive method with condom (42.4%) being the most common method, followed by pills (25.6%). One-fourth (25%) of the respondents reported having been pregnant at least once, and 21.4% reported having at least one induced abortion during the time working as a FEW. After controlling for other covariates in a multivariate logistic regression model, FEWs with a history of induced abortion remained significantly more likely to be currently working in a karaoke bar (AOR=1.75, 95% CI 1.10 to 2.78), to have worked longer as a FEW (AOR=1.42, 95% CI 1.06 to 1.43), to have had a greater number of sexual partners in the past 12 months (AOR=1.86, 95% CI 1.02 to 1.54), to be currently using a contraceptive method (AOR=1.52, 95% CI 1.01 to 2.29), to be able to find condoms when they needed them (AOR=2.03, 95% CI 1.09 to 3.82), and to report inconsistent condom use with non-commercial partners in the past 3 months (AOR=1.62, 95% CI 1.06 to 3.44). Conclusions This study highlights the high rates of unwanted pregnancies that ended in induced abortions among FEWs in Cambodia. Access of FEWs to quality sexual and reproductive healthcare services is deemed a high priority. Integrated interventions to improve sexual and reproductive health among these vulnerable women should be tailored to reach the most-at-risk groups.

BACKGROUND Compared to the general population, drug users are at increased risk of both poor mental health and HIV infection. The aim of this study was to determine the prevalence and correlates of high psychological distress among drug users in Cambodia. METHODS In April 2014, a two-stage cluster sampling method was used to randomly select 169 drug users from hotspots in Phnom Penh. Psychological distress was measured using General Health Questionnaire (GHQ-12). Bivariate and multivariable analyses were conducted to identify factors associated with levels of psychological distress among this population. RESULTS Our study found high prevalence of attempted suicide (15.3%), drug related arrests (46.2%), and incarceration (31.4%). Of the 169 participants, 42.0% were found to have high levels of psychological distress, indicating poor mental health. After adjustment, high levels of psychological distress were independently associated with suicidal ideation (p<0.001), higher frequency of drug use (p=0.02), sharing of needles or syringes (p=0.005), and having been sent to a rehabilitation centre (p=0.02). In addition, participants who perceived their overall health as being poor or very poor were more likely to have high levels of psychological distress (p=0.002). CONCLUSION Integration of mental health within HIV and needle and syringe exchange programmes is required to address psychological distress among drug users in Cambodia. Health system interventions, such as screening, referral, and training of health providers, need to be strengthened. In addition, interventions addressing social determinants of mental health and mitigation of frequent arrests and improving conditions in rehabilitation centres are required.

Objective To examine factors associated with HIV infection among transgender women in Cambodia. Design Cross-sectional study. Settings HIV high-burden sites including the capital city and 12 provinces. Participants This study included 1375 sexually active transgender women with a mean age of 25.9 years (SD 7.1), recruited by using respondent-driven sampling for structured questionnaire interviews and rapid finger-prick HIV testing. Primary outcome measure HIV infection detected by using Determine antibody test. Results HIV prevalence among this population was 5.9%. After adjustment for other covariates, participants living in urban areas were twice as likely to be HIV infected as those living in rural areas. Participants with primary education were 1.7 times as likely to be infected compared with those with high school education. HIV infection increased with age; compared with those aged 18–24 years, the odds of being HIV infected were twice as high among transgender women aged 25–34 years and 2.8 times higher among those aged ≥35 years. Self-injection of gender affirming hormones was associated with a fourfold increase in the odds of HIV infection. A history of genital sores over the previous 12 months increased the odds of HIV infection by threefold. Transgender women with stronger feminine identity, dressing as a woman all the time, were twice as likely to be HIV infected compared with those who did not dress as a woman all the time. Having never used online services developed for transgender women in the past six months was also associated with higher odds of being HIV infected. Conclusions Transgender women in Cambodia are at high risk of HIV. To achieve the goal of eliminating HIV in Cambodia, effective combination prevention strategies addressing the above risk factors among transgender women should be strengthened.

Karl Peltzer; Siyan Yi; Supa Pengpid

A large data gap remains on suicidal behaviors among youth in the Association of Southeast Asian Nations (ASEAN) countries, despite the increasing rates of suicide in Asian cultures that may be related to rapid economic changes and the loss of social stability. This study was therefore conducted to explore the prevalence of and factors associated with suicidal ideation and suicide attempts among university students in six ASEAN member states. Data were collected in a cross-sectional survey of 4675 undergraduate university students, mean age 20.6 years (SD=2.7), range of 18-30 years, from Cambodia, Indonesia, Malaysia, Myanmar, Thailand and Vietnam. The overall prevalence of ever suicidal ideation and ever suicide attempt among students in this study was 11.7% and 2.4%, respectively. Different rates of these suicidal behaviors were observed across the countries. In multivariable logistic regression models, suicidal ideation was significantly associated with psychosocial factors including childhood sexual abuse, depressive symptoms, involvement in physical fights, and poor academic performance as well as socio-environmental factors including living with parents or guardians and low involvement in organized religious activity. Suicide attempt was significantly associated with childhood sexual abuse, depressive symptoms, low involvement in organized religious activity and being underweight or overweight. Our findings suggest that individual-level strategies for suicide prevention should be targeted toward students with poor academic performance, mental health problems and a history of adverse childhood experiences. Particular attention should be paid to the role of families that could be a potential stressor in the lives of university students.

BackgroundDespite the success in promoting condom use in commercial relationships, condom use with regular, noncommercial partners remains low among key populations in Cambodia. This study explores factors associated inconsistent condom use with sweethearts among unmarried sexually active female entertainment workers (FEWs).MethodsIn 2014, the probability proportional to size sampling method was used to randomly select 204 FEWs from entertainment venues in Phnom Penh and Siem Reap for face-to-face interviews. Multivariate logistic regression analysis was conducted to examine independent determinants of inconsistent condom use.ResultsOf total, 31.4% of the respondents reported consistent condom use with sweethearts in the past three months. After adjustment, respondents who reported inconsistent condom use with sweethearts remained significantly less likely to report having received any form of sexual and reproductive health education (AOR = 0.49, 95% CI = 0.22–0.99), but more likely to report having been tested for HIV in the past six months (AOR = 2.19, 95% CI = 1.03–4.65). They were significantly more likely to report having used higher amount of alcohol in the past three months (AOR = 1.29, 95% CI = 1.01–1.99) and currently using a contraceptive method other than condoms such as pills (AOR = 4.46, 95% CI = 1.34–10.52) or other methods (AOR = 9.75, 95% CI = 2.07–9.86).ConclusionsThe rate of consistent condom use in romantic relationships among unmarried FEWs in this study is considerably low. The importance of consistent condom use with regular, non-commercial partners should be emphasized in the education sessions and materials, particularly for FEWs who use non-barrier contraceptive methods.

Background Preparing adolescents for transition into adult care and supporting their acquisition of self-health care management skills is a critical determinant of their post-transition HIV care outcomes. However, there is a scarcity of research on effective transition strategies. This study explores factors associated with adolescent preparedness for transition into adult care in Cambodia. Methods In August 2016, a cross-sectional study was conducted among 223 adolescents living with HIV aged 15–17, randomly selected from 11 antiretroviral therapy clinics, utilizing a structured questionnaire. The level of preparedness was determined using a pre-existing scale, and adolescents were categorized as having a high- or low level of preparedness for transition. Bivariate and multivariate analyses were conducted. Results Of 223 adolescents, 55.2% were male, and their mean age was 15.8 years. Overall, 53.3% had a high level of preparedness for transition. As part of the transition protocol, 2.7% had completed a transfer form, 24.7% had a transition case manager, 29.6% had been counselled about the transition, and 19.7% had visited an adult ART clinic. In multivariate analysis, a higher level of preparedness for transition was independently associated with older age (AOR 2.44, 95% CI 1.34–4.46; p = 0.004), family having received social support for their health (AOR 5.32, 95% CI 1.97–14.36; p = 0.001), knowing the kind of treatment they received (ART) (AOR 12.67, 95% CI 2.91–15.19; p = 0.001), trust in friends or family for HIV treatment (AOR 7.82, 95% CI 1.13–8.89; p = 0.008), receiving counseling on transition (AOR 3.17, 95% CI 1.15–8.76; p = 0.03), having a ‘Case Manager’ identified to support them during the preparation process for transition (AOR 3.89, 95% CI 1.08–13.96; p = 0.04), and satisfaction with preparation process for transition in general (AOR 0.35, 95% CI 0.03–0.87; p = 0.01). Conclusions A range of individual, social and health system and services factors may determine successful transition preparedness among adolescents in Cambodia. Strengthening implementation of age-appropriate and individualized case management transition at all sites, while creating supportive family, peer, and healthcare environments for adolescent transition is required.
