Diet, exercise, obesity, smoking and alcohol consumption in cancer survivors and the general population: a comparative study of 16 282 individuals.

Background: Cancer survivors may be particularly motivated to improve their health behaviours.
Methods: We compared health behaviours and obesity in cancer survivors with the general population, using household survey and cancer registry data.
Results: Cancer survivors were more likely than those with no history of cancer to eat fruit and vegetables (ORadj 1.41, 95% CI 1.19-1.66), less likely to engage in physical activity (ORadj 0.79, 95% CI 0.67-0.93) and more likely to have stopped smoking (ORadj 1.25, 95% CI 1.09-1.44).
Conclusions: Most health-related behaviours were better in cancer survivors than the general population, but low physical activity levels may be amenable to health promotion interventions.
