Introduction and Aims: People who use drugs (PWUD) face several mental health problems. This report aims to examine the prevalence of and factors associated with psychological distress among Cambodian PWUD., Design and Methods: Data used in our analysis were from the national survey of 1626 PWUD recruited through respondent-driven sampling method in Cambodia in 2012 to 2013. Distress was measured through self-report by using the 10-item Kessler Psychological Distress Scale (K10). All analyses were weighted., Results: Approximately half of PWUD had mild to severe psychological distress in the past four weeks (K10 ≥ 20). In the adjusted analysis, being female (odds ratio 1.60; 95% confidence interval 1.22, 2.12) and having experienced living in rehabilitation centres (odds ratio 2.46; 95% confidence interval 1.56, 3.87) were associated with a higher risk of having moderate or severe psychological distress (K10 ≥ 25)., Discussion and Conclusions: Psychological distress was prevalent among Cambodian PWUD. PWUD who were female or experienced living in rehabilitation centres were more likely to report distress. Policy makers should consider shifting further from compulsory institutionalised treatment model to community-based treatment program. Mental health assessment and mental health care services should be included in drug treatment programs and should be gender-sensitive. Further research investigating other mental disorders among PWUD are also needed., (© 2019 Australasian Professional Society on Alcohol and other Drugs.)

In Cambodia, HIV prevalence at 4% remains high among people who use drugs (PWUD). Complex and overlapping risk behaviors may enhance sexual transmission risk beyond PWUD. This study, therefore, aims to assess the factors associated with sexual risk behaviors among PWUD. Respondent Driven Sampling was used to recruit 1626 PWUD. Univariate and multivariate logistic regression analyses were used to identify factors associated with transmission risk including that high mental disorder scores were a strong predictor of sexual risk behaviors (odds ratio [OR] ranged from 1.9 to 2.8). Factors associated with sexual risk behaviors varied by gender: for men, these included geographical regions, non-married status, and heroin use; and for women, factors were age ≤20 years (OR = 5.4), living with friends (OR = 6.4), living in Central coastal region (OR = 6.1), and heroin use (OR = 4.8).

Background: Although HIV prevalence in Cambodia has declined to 0.6% among the general population, the prevalence remains high among female sex workers (14.0%) and men who have sex with men (2.3%). Over the past 10 years, the number of people who use drugs (PWUDs) has increased considerably. PWUDs, especially people who inject drugs (PWIDs), who have multiple sex partners or unprotected sex contribute to a higher HIV prevalence. This paper aims to estimate the prevalence of HIV across PWUD groups and to identify factors associated with HIV infection., Methods: Respondent-driven sampling (RDS) was used to recruit 1626 consenting PWUDs in 9 provinces in 2012. Questionnaires and blood specimens were collected. HIV prevalence estimates were calculated using RDSAT 7.1. Individual weightings for HIV were generated with RDSAT and used for a weighted analysis in STATA 13. Multivariate logistic regression was used to identify the independent factors associated with HIV prevalence., Results: Most of the PWUDs were men (82.0%), and 7.3% were PWIDs. Non-PWIDs, especially users of amphetamine-type stimulants (ATS), represented the larger proportion of the participants (81.5%). The median age for of the PWUDs was 24.0 years (IQR: 20-29). The HIV prevalence among the PWUDs was 5.1% (95% CI: 4.1-6.2), 24.8%, among PWIDs and 4.0% among non-PWIDs. The HIV prevalence among female PWIDs was 37.5, and 22.5% among male PWIDs. Four factors were independently associated with HIV infection: female sex, with AOR = 7.8 (95% CI: 3.00-20.35); age groups 21-29 and older (AOR = 10.3, 95% CI: 1.2-20.4); and using drugs for ≥12 months (AOR = 4.0, 95% CI: 1.38-11.35). Finally, injecting drugs remained a strong predictor of HIV infection, with an AOR = 4.1 (95% CI: 1.53-10.96)., Conclusion: HIV prevalence remains high among PWIDs. Harm reduction efforts, such as needle and syringe provision programs, must improve their coverage. Innovative strategies are needed to reach sub-groups of PWUDs, especially women who inject drugs. Furthermore, the large proportion of non-PWIDs, especially ATS users, should not be ignored. Therefore, combined HIV prevention and harm reduction programs should integrate ATS users.
