Health behaviours of school-aged children in Luxembourg

This report provides information on the health behaviours and health outcomes of adolescents aged 11 to 18 years old attending Luxembourg public and private schools whose teaching is based on the national curriculum in 2022. Family affluence showed an association with all health behaviours. Adolescents from a low family affluence background reported less often to: have breakfast every day, brush their teeth at least twice a day, eat fruits and vegetables daily and practise physical activity; in addition, they reported more often to consume soft drinks daily and a higher prevalence of overweight/obesity is observed, when compared to their peers with a high affluence family background. Age and gender also presented associations with health behaviours, but they were not systematic, and its direction varied. Moreover, this report analyses the relationship between physical activity, on the one hand, and overweight/obesity and well-being, on the other hand. Independently of the consumption of fruits, vegetables, soft drinks and sweets, the higher the frequency of physical activity, the lower the chances of being overweight and obese. In addition, higher levels of physical activity were associated with higher levels of well-being.
