Weight gain (mean ± SE) from baseline (Y0) to Year 1 (Y1) by Y1 quit status (point-prevalence abstinence) and steps/day status (low or high) at Y0 and again at Y1. Data analyzed for participants from a randomized controlled trial comparing the efficacy of different smoking cessation pharmacotherapies (Wisconsin, 2005-2008). Adjusted for age, sex, Y0 weight, education, income, cigarettes/day, and caloric intake. Steps/day were split at the median value at Y0 (7161 steps/day) and at Y1 (7250 steps/day), and participants were classified as low or high at each time point. pinteraction=0.33, pquit≤0.0001, psteps=0.002.
