This secondary analysis aims to describe, over time, the relationship between HIV disease progression and intention to quit cigarette smoking among current monocigarette users with and without a lifetime history of polytobacco use. Participants completed a baseline assessment at the time of HIV care initiation and four follow-up assessments (3, 6, 9, and 12-months). Assessments included biochemically verified smoking status and audio computer-assisted self-interviews assessing psychosocial, substance use, and clinical variables known to influence smoking behaviors. Using linear and generalized linear fixed-effects models, we modeled the covariance structure for the repeated outcome measures (intention to quit and 7-day point prevalence smoking abstinence) across the study time points and included a three-way interaction term to examine the effects of disease stage and tobacco product use. Participants (N = 357) were 73.1% male, 67.3% black/African American, and had a mean (SD) age of 38.7 (10.6) years. At baseline, lifetime polytobacco users reported significantly worse HIV-related symptoms and burdens, illness perception, social support, and nicotine dependence. Intention to quit, but not smoking abstinence, was predicted by a three-way interaction between time from HIV care initiation, disease progression, and tobacco product use (p = .04). Overall, progressive HIV was associated with greater intention to quit smoking cigarettes. However, the relationship differed over time between the two tobacco product groups. Future studies should consider tailoring the timing of cessation interventions upon disease stage and lifetime history of polytobacco use.
