All models adjust for baseline values. Additionally, models adjust for smoking (weight); self-reported physical activity, smoking, weight loss attempt over previous 6 months (waist circumference); education, heart condition, weight loss attempt over previous 6 months (walking for exercise); BMI, self-reported physical activity, education, employment, heart condition, musculoskeletal condition (fruit intake); BMI, ethnicity, heart condition (vegetable intake); age, BMI, heart condition, mental illness (FFBQ fat); previously diagnosed cancer (FFBQ Fibre); previously diagnosed cancer, heart condition (FFBQ Total).
