Pupils were asked to indicate the frequency of eating fruit and drinking coke or other soft drinks that contain sugar by ticking one of the following seven responses: ‘never’, ‘rarely/less than once a week’, ‘once a week’, ‘2–4 times a week’, ‘5–6 times a week’, ‘once a day, every day’ and ‘more than once a day, every day’. Response options were recoded into dichotomous outcome variables (1=daily, 0=less than daily).
