Defining and assessing evidence for the effectiveness of technical assistance in furthering global health.

In an era when health resources are increasingly constrained, international organisations are transitioning from directly managing health services to providing technical assistance (TA) to in-country owners of public health programmes. We define TA as: 'A dynamic, capacity-building process for designing or improving the quality, effectiveness, and efficiency of specific programmes, research, services, products, or systems'. TA can build sustainable capacities, strengthen health systems and support country ownership.

Focusing HIV prevention on those most likely to transmit the virus.

Despite some success in reducing HIV incidence, the global epidemic continues to grow. For every person with AIDS in developing countries placed on treatment in 2005, many others were newly infected. We need more effective prevention programs that focus interventions on those most at risk for HIV transmission (MART), particularly those with 1) high behavioral risk and 2) high viral loads due to acute or recent infection, co-infections with other diseases, high viral set points, or untreated AIDS.

Factors associated with HIV testing, condom use, and sexually transmitted infections among female sex workers in Nha Trang, Vietnam.

This study examined predictors of HIV testing, successful condom negotiation with clients, and self-reported sexually transmitted infections (STIs) among Vietnamese female sex workers (FSW). Data were collected by using face-to-face interviews from a community sample of 610 FSW from Nha Trang city during October-December, 2000. Having had an HIV test was associated with having spent time in a rehabilitation center.

Sex workers in Vietnam: how many, how risky?

Because of concerns for HIV risks and need to plan effective programs, we assessed the number and risks of sex workers in Nha Trang City, Vietnam. Sex workers were contacted in streets, beaches, bars, and restaurants, and a capture-recapture method was used to estimate their number. An estimated 444 women worked on the streets and beach ("direct" sex workers) and 486 worked in bars and restaurants or other facilities ("indirect" sex workers).

Peer education for HIV prevention in the Socialist Republic of Vietnam: a national assessment.

In 2000, the government of Vietnam conducted the first assessment of its national peer education program for HIV prevention. Twenty (32%) of Vietnam's 61 provinces and urban areas had functioning peer education programs, and program coordinators of all 20 were interviewed regarding their programs. In addition, on-site reviews were done for 10 of the 20 programs, including interviews of peer educators and high-risk persons in each program.
