Drug use, sexual behaviours and practices among female sex workers in Hanoi, Viet Nam a qualitative study

摘要

To examine the causes of a rapid increase of HIV infection among female sex workers (FSWs) in Hanoi, Viet Nam, a qualitative study of sex workers was conducted there in June 2001 to study their risk characteristics, their relationships with drug users, and to identify potential factors playing a role in the recent rise of HIV. Thirty-seven FSWs in different districts were recruited for in-depth interviews and group discussions about drug use and sexual behaviour. They reported higher condom use with irregular clients, although use was still low with regular clients and their love mates. Drug use is common, and many FSWs inject, especially street-based sex workers. There are interactions between drug users and FSWs through both injecting and unsafe sexual contact. Drug-injecting street-based FSWs are the highest risk sex worker group for HIV infection, and potentially serve as a major bridge through their clients to the general population. Prevention of HIV transmission will depend on the risk behaviour of the general population and the success of intervention strategies targeting FSWs, especially street-based FSWs and those injecting drugs.
