Needle sharing and sex-related risk behaviours among drug users in Shenzhen, a city in Guangdong, southern China

Abstract

Intravenous drug users (IDUs) are at high risk of contracting HIV, but there is a geographic bias in such research efforts in China. The aim was to study the pattern of needle sharing and sex-related risk behaviours among drug users in southern China. About 260 drug users in a detoxification centre completed an anonymous questionnaire (response rate=87.3%). The results show that needle sharing among IDUs was prevalent (60.6% and 45.3% for male and female IDUs, respectively); the sharers were often friends, spouses, and acquaintances. Few IDUs sterilized the used needles properly. Commercial sex behaviours (males: 44%; females: 60%) as well as multiple partnership (males: 60%; females: 53%) were also prevalent among all male and female drug users studied. Inconsistent condom use with commercial sex partners, spouses, and regular sex partners was also very common. Yet, few of all drug users studied perceived the susceptibility of contracting HIV (11%) or sexually transmitted diseases (24%) in the future. A better HIV-related knowledge level was associated with lower levels of risk behaviours. It is concluded that harm reduction programmes are urgently warranted in China.
