HIV/AIDS-related knowledge awareness and risk behaviors among injection drug users in Maanshan, China: a cross-sectional study.

BACKGROUND

Unsafe injection practices significantly increase the risk of human immunodeficiency virus (HIV) infection among injection drug users (IDUs). Little is known about how demographic characteristics of IDUs are linked to HIV-related risk behaviors in the central regions of China.

METHODS

A cross-sectional survey was conducted at Mandatory Detoxification Centers (MDCs) and the community in Maanshan, China.

RESULTS

Of the 916 IDUs, 96.4 % reported a history of heroin use during the past year, 93.4 % had HIV/AIDS knowledge, 16.8 % reported receptive syringe sharing and 12.2 % reported inconsistent condom use in commercial sex in the past year. Unsafe injection practice was associated with increased odds of minority ethnicity, lower level of education, and no peer education in the past year. Unsafe sex practice was associated with increased odds of being single, 18-30 years of age, non-local residence, and history of methamphetamine use in the past year.

CONCLUSIONS

Integrated interventions to promote safe injection and protected commercial sex practices targeting IDUs must also consider individual and socio-environmental factors.
