evidence: Analysis of weight change in those successful at stopping smoking was underpowered (66%) but indicated greater mean weight gain in intervention subjects (3.9 (SD 3.1) vs. 2.7 (SD 3.7) kg). Between group differences were not significant (p = 0.23, 95% CI −0.9 to 3.5) however the confidence interval is wide and includes a loss of −0.9 kg, thus the possibility of an effect in favour of the intervention cannot be excluded.
intervention: 24-week intervention focussed on improving food choice and minimising weight gain
comparator: Usual care comprised of 7?weeks of group support sessions
outcome: Smoking cessation
