Assessed by multiple linear regression, reporting beta coefficients. Vigorous physical activity includes walking, cycling and sport. All models are adjusted for baseline PA; the adjusted model is also adjusted for age, sex, randomisation group, marital status, income level, education level and occupation type
95% CI 95% confidence interval, h/w hours per week
