Trends and determinants of HIV transmission among men who inject drugs in the Pokhara Valley, Nepal: analysis of cross-sectional studies.

ABSTRACT:

Background

HIV is a major public health issue around the world, especially in developing countries. Although the overall prevalence of HIV in Nepal is relatively low, there are specific sub-populations where the prevalence is far higher than the national average. One of these sub-groups is male people who inject drugs (male PWIDs). In order to understand the reasons for the differences in prevalence, a series of socio-demographic, behavioural and knowledge-based risk factors need to be assessed.

Methods

The study used a series of 7 cross-sectional survey datasets from Pokhara (Nepal), collected between 2003 and 2017 (N?=?2235) to investigate trends in HIV prevalence among male PWIDs by socio-demographic and behavioural and knowledge-based risk factors. A series of logistic regression models were conducted to investigate the association between study factors and HIV.

Results

HIV prevalence decreased from the levels seen in 2003 (22.0%) and 2005 (21.7%), with the lowest prevalence recorded in 2015 (2.6%), however prevalence has increased in the most recent period (4.9%). A lower risk of HIV was associated with younger age (<=24?years compared to >?24?years, OR?=?0.17, 95% CI?=?0.10-0.31), being married (OR?=?1.91, 95% CI?=?1.25-3.02) and shorter duration of drug use (<=4?years compared to >?4?years, OR?=?0.16, 95% CI?=?0.09-0.29). A higher risk of HIV was associated with low (compared to secondary or higher) education level (OR?=?2.76, 95% CI?=?1.75-4.36), a lack of addiction treatment (OR?=?2.59, 95% CI?=?1.64-4.08), and recent use of unsterilized injection equipment (OR?=?2.22, 95% CI?=?1.20-4.11).

Conclusion

The prevalence of HIV in male PWIDs in Pokhara has been variable, but overall has reduced in recent years to 2.6% before increasing in 2017 to 4.9%. The main determinants which increase the risk of HIV among male PWIDs in Pokhara are low education level, a lack of treatment for drug addiction and the recent use of unsterilised equipment. Each of these indicate the need to improve addiction treatment and education programs for intra-venous drug use to aid this key population in avoiding risk-taking behaviours.

Project description:ObjectivesTo estimate the prevalence of anxiety and depression and identify the associated factors among people with type 2 diabetes mellitus (T2DM) visiting diabetes clinics of Pokhara Metropolitan, Nepal.DesignCross-sectional study.SettingThree diabetes clinics in Pokhara Metropolitan, Nepal, from May to July 2021.Participants283 people with T2DM visiting selected diabetes centres of Pokhara Metropolitan.Outcome measuresAnxiety and depression were the outcome measures. Face-to-face interviews were conducted using a structured questionnaire comprising information related to participants' sociodemographic profile and several factors along with Hospital Anxiety and Depression-Anxiety subscale and Patient Health Questionnaire-9 to assess the levels of anxiety and depression, respectively. Pearson's Χ2 tests and binary logistic regression were performed to examine association between dependent and independent variables at 5% level of significance.ResultsThe prevalence of anxiety and depression was 31.4% (95% CI 26.2% to 37.5%) and 36.4% (95% CI 30.8% to 42.0%), respectively. Anxiety was found to be associated with a lower level of perceived social support (adjusted OR (AOR) 2.442, 95% CI 1.020 to 5.845), multiple complications (AOR 2.758, 95% CI 1.015 to 7.334) and comorbidities (AOR 2.110, 95% CI 1.004 to 4.436), severe COVID-19 fear (AOR 2.343, 95% CI 1.123 to 4.887) and sleep dissatisfaction (AOR 1.912, 95% CI 1.073 to 3.047). Economical dependency (AOR 1.890, 95% CI 1.026 to 3.482), no insurance (AOR 2.973, 95% CI 1.134 to 7.093), lower perceived social support (AOR 2.883, 95% CI 1.158 to 7.181), multiple complications (AOR 2.308, 95% CI 1.585 to 6.422) and comorbidities (AOR 2.575, 95% CI 1.180 to 5.617), severe COVID-19 fear (AOR 2.117, 95% CI 1.009 to 4.573), alcohol use (AOR 2.401, 95% CI 1.199 to 4.806) and sleep dissatisfaction (AOR 1.995, 95% CI 1.093 to 3.644) were found to be associated with depression.ConclusionThis study showed high prevalence levels of anxiety and depression among people with T2DM. Strengthening social support and focusing on people with diabetes suffering from comorbidity and complications could help to reduce their risk of mental health problems.

Project description:Injection drug use is prevalent in northwestern Bangladesh. We sought to explore the context of needle/syringe sharing among persons who inject drugs (PWID), examining risk exposures to blood-borne infections like the human immunodeficiency virus (HIV) and hepatitis in a region where these dual epidemics are likely to expand.We used a qualitative research approach to learn about injection practices, conducting 60 in-depth interviews among PWID. We then conducted 12 focus group discussions (FGDs) that generated a checklist of salient issues, and followed up with personal observations of typical days at the drug-use venues. Content and interpretative frameworks were used to analyze qualitative information and socio-demographic information, using SPSS software.We found that needle/syringe-sharing behaviours were integrated into the overall social and cultural lives of drug users. Sharing behaviours were an central component of PWID social organization. Sharing was perceived as an inherent element within reciprocal relationships, and sharing was tied to beliefs about drug effects, economic adversity, and harassment due to their drug user status. Carrying used needles/syringes to drug-use venues was deemed essential since user-unfriendly needle-syringe distribution schedules of harm reduction programmes made it difficult to access clean needles/syringes in off-hours. PWID had low self-esteem. Unequal power relationships were reported between the field workers of harm reduction programmes and PWID. Field workers expressed anti-PWID bias and judgmental attitudes, and also had had misconceptions about HIV and hepatitis transmission. PWID were especially disturbed that no assistance was forthcoming from risk reduction programme staff when drug users manifested withdrawal symptoms.Interventions must take social context into account when scaling up programmes in diverse settings. The social organization of PWID include values that foster needle-syringe sharing. Utilization and impact of risk reduction programmes might be improved with expanded clean needle/syringe distribution at times and venues convenient for PWID, better trained and non-judgmental staff, and medical assistance for health problems, including drug withdrawal symptoms.

Project description:Hepatitis C virus (HCV) chronically infects over 180 million people worldwide, with over 350,000 estimated deaths attributed yearly to HCV-related liver diseases. It disproportionally affects people who inject drugs (PWID). Currently there is no preventative vaccine and interventions feature long treatment durations with severe side-effects. Upcoming treatments will improve this situation, making possible large-scale treatment interventions. How these strategies should target HCV-infected PWID remains an important unanswered question. Previous models of HCV have lacked empirically grounded contact models of PWID. Here we report results on HCV transmission and treatment using simulated contact networks generated from an empirically grounded network model using recently developed statistical approaches in social network analysis. Our HCV transmission model is a detailed, stochastic, individual-based model including spontaneously clearing nodes. On transmission we investigate the role of number of contacts and injecting frequency on time to primary infection and the role of spontaneously clearing nodes on incidence rates. On treatment we investigate the effect of nine network-based treatment strategies on chronic prevalence and incidence rates of primary infection and re-infection. Both numbers of contacts and injecting frequency play key roles in reducing time to primary infection. The change from "less-" to "more-frequent" injector is roughly similar to having one additional network contact. Nodes that spontaneously clear their HCV infection have a local effect on infection risk and the total number of such nodes (but not their locations) has a network wide effect on the incidence of both primary and re-infection with HCV. Re-infection plays a large role in the effectiveness of treatment interventions. Strategies that choose PWID and treat all their contacts (analogous to ring vaccination) are most effective in reducing the incidence rates of re-infection and combined infection. A strategy targeting infected PWID with the most contacts (analogous to targeted vaccination) is the least effective.
