Smoking status was based on one question with the following options: never, ex-regular smoker, ex-occasional smoker, current smoker. Alcohol use was derived from the question “On how many days in the last 7 days did you have an alcoholic drink?”. Long standing illness included at least one illness from a list of body systems (ie, nervous system, heart and circulatory system). The definition of psychological distress was based on the General Health Questionnaire (GQH) comprising 12 questions related with psychological health.
BMI, body mass index; MVPA, moderate-to-vigorous physical activity; max, maximal; y, years.
