HIV prevention for injection drug users in China and Vietnam: policy and research considerations.

A pattern of serious injection drug user (IDU) driven HIV epidemics in Asia, with emerging evidence of generalization through heterosexual transmission, indicates the need for interventions focusing on both drug- and sex-related risk reduction. In a cross-border HIV prevention project for IDUs in northern Vietnam and southern China, peer educators disseminated risk reduction information to IDUs in the community and provided 20,000-25,000 sterile needles/syringes and 4,000-6,000 condoms per month. Since implementation of these interventions, the frequency of both injecting and sexual risk behaviours fell significantly, HIV prevalence among IDUs declined or stabilized, and HIV incidence dropped. There is official support for harm reduction interventions in both countries but this appears precarious in view of persistently powerful political and financial support for a law enforcement approach. Moreover, the simultaneous pursuit of inconsistent policies can have negative effects on the implementation of interventions. A harmonized and consistent policy environment is needed. Most of the evidence for efficacy of community-based HIV prevention comes from the developed world, but well-designed evaluations of such interventions in Asia and elsewhere in the developing world would have a better chance to influence policy decisions there. A synergistic approach to research, policy development, and service delivery is best calculated to achieve positive results in the struggle against HIV/AIDS in developing countries.

Acceptability of formulations and application methods for vaginal microbicides among drug-involved women: results of product trials in three cities.

BACKGROUND AND OBJECTIVES: Female-controlled methods of HIV prevention, such as vaginal microbicides, are urgently needed, particularly among drug-involved women. Acceptability research is critical to product development. GOAL: To assess the acceptability of forms and application methods for future microbicides. DESIGN: Eighty-four drug-involved women were introduced in groups to three lubricant products, asked to try each for 3 weeks, and scheduled for individual follow-up interviews. RESULTS: Participants and their partners felt positive about the products, and expressed willingness to use microbicides if they were shown to be effective against HIV. Women agreed on product characteristics that influenced their reactions (e.g. ease of insertion, degree of "messiness"), but often disagreed on whether their reactions to these characteristics were positive or negative. CONCLUSION: Development of acceptable and effective HIV-prevention products depends on understanding the interaction between characteristics of the products and the characteristics and perceptions of women. Levels of sexual risk and acceptability factors based on drug-use patterns, race and ethnicity, culture, age, and types and attitudes of male partners suggest that a "one size fits all" approach will not win broad acceptance among drug-involved women.

Drug-involved women as potential users of vaginal microbicides for HIV and STD prevention: a three-city survey.

We wished to obtain potential users' perspectives on vaginal microbicides from a population of women at high risk for HIV. We conducted a face-to-face survey of convenience samples (total n = 743) of drug-using women and female sexual partners of male injection drug users in Bridgeport, Connecticut, Providence, Rhode Island, and San Juan, Puerto Rico. Ninety percent of respondents said that they would be very likely to use microbicides with paying partners and 78% with primary partners (p = 0.001). High hypothetical likelihood of use was expressed even after several potential product characteristics (e.g., causes minor vaginal irritation or burning) were rated as unacceptable. Latinas had significantly higher predicted likelihood of use with primary (p = 0. 001) and paying partners (p = 0.018) than blacks and whites. Eighty percent of respondents preferred products that enhance sexual pleasure by providing additional lubrication or "wetness." More than 80% of respondents said that they would want their primary partners to know of their microbicide use, and 42% (p = 0.001) said that they would want their paying partners to know. Women's concern about a paying partner's violent response to suggested use of risk reduction measures was inversely related to predicted likelihood of microbicide use (p = 0.045). Microbicides should be assessed in the context of the potential users' actual relationships and cultures. Achieving broad acceptability among drug-involved women will require a range of products.

Reaching seriously at-risk populations: health interventions in criminal justice settings.

More than 6 million people are under some form of criminal justice supervision in the United States on any given day. The vast majority are arrested in and return to urban, low-income communities. These are men, women, and adolescents with high rates of infectious diseases such as HIV/AIDS, other sexually transmitted diseases (STDs), and tuberculosis (TB), as well as substance abuse and other health problems. A review of recent literature indicates that an increasing problem for these populations is that they have had little prior access to primary health care or health interventions, and many are returning to their communities without critical preventive health information and skills, appropriate medical services, and other necessary support. Periods of incarceration and other criminal justice supervision offer important opportunities to provide a range of health interventions to this underserved population, and general evaluations show the potential for this strategy. Public health and criminal justice agencies have the expertise and should collaborate to provide interventions needed by incarcerated populations. Moreover, many recently released inmates require primary care for HIV/AIDS, other STDs, and TB. Consequently, timely discharge planning is essential, as are linkages with community-based organizations and agencies that can provide medical care, health education, and necessary supportive services.
