Weight gain (mean ± SE) from baseline (Y0) to year 1 (Y1) by Y1 quit status (point-prevalence abstinence) and quartile of “averaged” mean steps/day (the mean of the Y0 and Y1 scores). 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 for quartiles 1 through 4 respectively are: < 5341, 5341-7137, 7138-9721, and >9721 steps/day. pinteraction=0.63, pquit≤0.001, psteps=0.06
