1. Multilevel psychological, social, and
environmental factors, and their interactions were all important
correlates of obesity-related behaviours (physical activity, sedentary
behaviour, and dietary behaviours) and body mass index in Hong Kong
adolescents.
2. Parents may influence adolescents’ obesity-related behaviours by being good role models, establishing appropriate rules about eating and providing material and emotional support for obesity-preventive behaviours.
3. Schools and communities may provide opportunities for engagement in physical activity and healthy eating, as well as for reducing sedentary behaviour and intake of unhealthy foods.
4. Environmental correlates of adolescents’ obesity-related behaviours somewhat varied by sex, age, and level of enjoyment of specific behaviours.
