Abstract
This study sought to determine the prevalence of needle sharing and high HIV risk sexual behaviors and to identify characteristics associated with these practices in southern Thailand. Data were obtained using a structured questionnaire from 298 male intravenous drug users (IVDUs) seen in a methadone clinic during the previous year. The prevalence of HIV was 37%, and that of needle-sharing in the preceding 6 months was 45%, although only 10% claimed to have had unsafe sex with a casual partner or prostitute in the same period. Determinants for needle sharing included shorter duration of drug injection, diminished knowledge of HIV prevention, a carefree attitude toward the risk of HIV infection, and lower levels of income. Young single IVDUs with a low knowledge of HIV prevention were most likely not to use a condom. In conclusion, needle sharing among the study subjects was still a common practice, whereas high HIV risk sexual behavior was not. Attitudinal change may be necessary to reduce needle-sharing behavior and not just information on disease transmission.
