Health behaviours will be measured by means of self-reported questionnaires in individuals aged 12, 15 and 18 years or when necessary, with support from parents. To identify clusters, we will consider smoking as current/past/never, alcohol use as hazardous/moderate/abstainer, physical activity as inactive/moderately active/sufficiently active and consumption of fruit and vegetables as sufficient/insufficient.
