The development of peer educator-based harm reduction programmes in Northern Vietnam

Introduction. Injecting drug use remains an important risk factor for transmission in Vietnam, with an estimated 50% of the 290 000 people living with HIV/AIDS reporting injecting drug use as a risk factor. Despite this, effective harm reduction interventions are generally lacking. This paper describes the implementation of peer-based harm reduction programmes in two rural provinces of Vietnam. Design and Methods. Peer educators were trained in basic HIV prevention, including harm reduction. After significant preparation work with the Provincial AIDS Committees of Bac Giang and Thanh Hoa and other relevant national, provincial and local authorities, the interventions were commenced. Harm reduction interventions were delivered through outreach as well as on-site. This included needle and syringe distribution and collection. Results. Community advocacy occurred throughout the life of the project. Local authorities and peers believed that while there was a general reduction in stigma and discrimination, legal barriers associated particularly with the carrying of injecting equipment remained. This impacted upon the ability of peer educators to work with their clients. Conclusion. Peer-based delivery of harm reduction intervention is acceptable. Harm reduction interventions, including needle and syringe programmes, are feasible and acceptable in these two rural Vietnamese provinces. Community acceptance and uptake of these interventions is key to successful expansion across the region. Active participation by families of drug users seems crucial. This initiative demonstrates that despite a difficult policy environment, peer-delivered needle and syringe programmes are feasible within a rural Asian environment as long as there is adequate local political and community support.

Predictors of HIV Sexual Risk Behaviors in a Community Sample of Injection Drug-Using Men and Women

Injection risk practices and unprotected sex between injection drug users (IDUs) and their sexual partners are responsible for a high proportion of AIDS cases and new HIV infections in the United States. The purpose of this study was to investigate the links between drug use behaviors and psychosocial factors with high-risk sexual behaviors among male and female IDUs. Understanding the determinants of sexual risk practices among drug users can lead to the development of more effective programs to prevent sexual HIV and STD transmission. This study enrolled a community sample of 101 IDUs (males = 65, females = 36), primarily African American and unemployed, who injected drugs and had unprotected sex in the past 3 months. The sample was categorized into highest sexual risk (multiple partners and intercourse without condoms) and lower sexual risk subgroups. Univariate analyses showed that IDUs at highest sexual risk had lower sexual risk reduction self-efficacy (p =.01) and were more likely to be African American (p =.02). Drug users at highest sexual risk also used noninjected cocaine and crack more frequently (p =.05), were less likely to inject heroin (p =.04), and tended to more often inject cocaine (p =.05). IDUs at highest sexual risk also tended to more often use crack and methamphetamines. Logistic regression analyses showed that injecting cocaine or crack, sexual risk reduction self-efficacy, and race were independent predictors of sexual risk behavior levels. Sexual risk reduction programs for this population are needed, with HIV prevention programs tailored to specific IDU risk reduction needs.     

Performance and coverage of HIV interventions for injection drug users: Insights from triangulation of programme, field and surveillance data from Pakistan

Introduction

Nearly 20% of the estimated 84,000 injecting drug users in Pakistan are HIV infected. Non-governmental organisations have implemented HIV interventions for IDUs in 7 cities in Pakistan. Here we report on the performance, coverage and costs of these interventions.

Methods

National HIV bio-behavioural surveillance data were used to measure effectiveness of interventions by comparing HIV prevalence and behavioural trends in intervention and non-intervention cities. Coverage was measured by comparing the supply of syringes with the total syringe need and intervention cost per IDU served per year was calculated.

Results

The NGOs registered 20,640 IDUs (original targets: <10,000); provided 66% of new syringes for all registered IDUs and 75% for all estimated street-based IDUs. This compared to a national coverage of about 13%. Intervention cities had higher baseline HIV prevalence, reflecting their choice as intervention sites. More IDUs from intervention cities (59% vs. 27%) reported always using a clean syringe. Condom use with last sexual partner (24% vs. 11%) and HIV prevention knowledge were also higher amongst this group (all at p < 0.001). HIV prevalence in intervention cities remained unchanged in Faisalabad (13%) and Quetta (10%) but increased in Karachi (26-30%) and Lahore (4-7%). Coverage of sterile syringes for intervention cities was 30% compared to 13% nationwide. However within city, coverage varied from 30 to 99%. The costs of services varied widely by NGOs from USD 146 to 403.

Conclusions

IDUs interventions are performing well in some Pakistani cities. However, considerable expansion is needed to increase nationwide coverage.     

2008年柳州市艾滋病监测结果分析

目的了解柳州市2008年艾滋病流行现状,为采取有效控制措施提供科学依据。方法采用哨点监测、综合监测、自愿咨询检测、重点人群筛查和专题流行病学调查等方法,收集全市艾滋病病毒感染资料和艾滋病病例报告资料。结果2008年全市共筛查监测各类重点人群178565人,检出HIV抗体（初筛）阳性者2356人,检出率1．32％。年龄最小0．5岁,最大84岁,20—44岁者占72．38％,传播途径经静脉吸毒占19．53％,性传播占58．98％,母婴0．89％。结论柳州市HIV流行已经由静脉吸毒人群经性乱人群向一般人群蔓延,静脉吸毒、性乱人群为该市艾滋病传播的重要因素。
