What the trial is, and whether it could suit you
The investigators propose to use a parallel group, randomized controlled trial to test the efficacy of a 13-week personalized approach to reducing smoking intervention versus a second approach using a different health intervention on smoking cessation, healthy sleep metrics, and biomarkers of cardiovascular risk in a sample of 200 treatment-seeking smokers who are adults living with HIV (ALHIV). To enroll in the study, treatment-seeking ALHIV smokers will undergo phone and in-person study eligibility assessments, including a history, physical examination, screening laboratory tests, and an overnight in-home objective sleep assessment. Eligible subjects (N=200) will be randomized to the 13-week Approach 1 (N=100) or Approach 2 (N=100) condition. All subjects will receive a 12-week course of varenicline (beginning in week 2) and 8 individual 15-minute smoking cessation counseling sessions
