Wellness Intervention for Smoking and HIV

• Status: Not yet recruiting
• Trial end date: 2025-03-01
• Target enrollment: 0
• Participant gender: All

Summary

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 [weeks 1, 2, 3 (target quit date), 5, 7, 9, 11, 13]. At each in-person counseling session, 30-45 minutes of Approach 1 or Approach 2 counseling will be provided as well. While receiving varenicline, liver function tests will be monitored at least monthly, and blood pressure at each study visit for safety reasons. Study measures are collected at all time points including EOT (week 13), and 6-month follow-up (6MFU).
