Although the deleterious effects of HIV stigma are well documented, less is known about how various types of stigma impact older adults living with HIV disease and what factors exacerbate or lessen the effects of HIV stigma. Using cross-sectional data from the OHTN cohort study (OCS), we undertook multiple linear regression to determine the predictors of overall HIV stigma, and enacted, anticipated, and internalized stigma subscales in a sample of OCS participants age 50 and over (n=378). Being female, heterosexual, engaging in maladaptive coping, and having poor self-rated health were associated with greater overall stigma while being older, having greater mastery, increased emotional-informational social support, and a longer time since HIV diagnosis were associated with lower levels of stigma. The final model accounted for 31% of the variance in overall stigma. Differences in these findings by subscale and implications for practice are discussed.
