OBJECTIVE: Drug adherence is crucial to the success of highly active antiretroviral therapy (HAART) in the treatment of HIV disease. Adherence to HAART and its determinants may, however, differ across HIV/AIDS populations. METHODS: We retrospectively studied drug adherence by self-report in HIV-1 infected Chinese patients who have been on HAART for at least 1 year as at the end of year 2000. HAART is defined as three or more antiretrovirals with at least one protease inhibitor or non-nucleoside analogue reverse transcriptase inhibitor. RESULTS: The last drug adherence level assessed by self-report in 161 Chinese patients were: grade A (100%) - 130, 80.7%; grade B (95-99%) - 25, 15.5%; grade C (90-94%) - three, 1.9% and grade D (< 90%) - three, 1.9%. Patients with full adherence were more likely to have undetectable (< 500 copies/mL) plasma virus level (adjusted OR, 4.22; 95% CI, 1.75-12.33). Patients' demographics, HIV disease status and antiretroviral regimen did not affect adherence. Partial drug adherence was, however, independently associated with the psychosocial factors of missing clinic appointments (adjusted OR, 3.13; 95% CI, 1.23-8.33), forgetfulness (adjusted OR, 4.55; 95% CI, 1.64-12.5) and a busy work life (adjusted OR, 6.67; 95% CI, 1.75-25). CONCLUSION: There were similarities and differences in determinants affecting HAART adherence in Chinese compared with other patients. Psychosocial factors rather than HIV disease or treatment were more important factors in our Chinese patients. The relevance of patient populations and care setting for adherence to HAART shall be further studied.
