A randomized controlled trial to reduce post-cessation weight gain
Authors' conclusion
Results indicated the Stability and the Loss interventions were effective for preventing post-smoking cessation weight gain, with the Loss group having the benefit of sustained weight loss. These interventions may be helpful to implement to combat weight gain and potentially facilitate smoking cessation.
Study context
- Population
- Adults smoking ≥5 cigarettes/day for the last year and interested in quitting, initially recruited from Memphis, TN, USA, expanded nationally with COVID-19 onset; 2018–2022276 completed 12-month follow-up
- Participants
- 305 adults
- Comparison
- Weight stability and weight loss interventions vs self-guided bibliotherapy weight management
- Primary endpoint
- Weight change
- Follow-up
- 12-month follow-up
