Hazardous and harmful use of alcohol and/or other drugs and health status among South African patients attending HIV clinics.

There is growing recognition of the influence of substance use, particularly alcohol use, on HIV disease progression. This study investigated how hazardous/harmful use of alcohol and drugs impacts the health status of 1503 patients attending HIV clinics. Of the sample, 37 % indicated hazardous/harmful drinking and 13 % indicated a drug problem. Hazardous/harmful use of alcohol and drugs was significantly related to health status, with participants using substances more likely to have TB-positive status (χ(2) = 4.30, p < 0.05), less likely to be on ARVs (χ(2) = 9.87, p < 0.05) and having lower CD4 counts (t = 4.01, p < 0.05). Structural equation modelling confirmed the centrality of hazardous/harmful use of alcohol as a direct and indirect determinant of disease progression. Based on these findings it is recommended that patients attending HIV clinics be routinely screened for problematic alcohol and/or drug use, with strong emphasis on ensuring ARV adherence in those with problematic alcohol use.
