Abstract

Context: In China, the social stigma of both substance use and HIV remains major barriers. HIV+ individuals have been demonstrated to have higher psychosocial distress in the literature. To ensure quality of life among HIV+ Chinese individuals, self-efficacy in HIV-related management including substance use and anxiety is the key to suppress viral load and maintain healthy lives.

Objectives: We examine the mediation relationship among substance use, anxiety, and self-management efficacy.

Method: A cross-sectional study design was used. 137 HIV+ individuals were recruited from two premier Chinese hospitals: Beijing's Ditan Hospital and Shanghai's Public Health Clinic Center (SPHCC).

Results: HIV+ substance users had significantly lower HIV-management efficacy and higher anxiety scores. About a third of the relations between substance use and anxiety was mediated by HIV-management self-efficacy. Those who used substances in the previous week had higher anxiety levels suggesting the presence of a recent effect. Their higher levels of anxiety could be largely explained by their lower HIV-management efficacy.

Conclusion: It is useful for healthcare providers to assess substance use behaviors in HIV+ individuals as well as provide support in managing anxiety in this population. Meanwhile, enhancing self-management efficacy to ensure healthy lifestyles may support achieving optimal lives with HIV.
