Body size and lifestyle in an urban population entering adulthood: the 'Grow up Gothenburg' study.

AIM: To present data on body size, lifestyle and health status in students in their final year in high schools in Gothenburg area, Sweden, with specific attention to origin and gender.
METHODS: Weight, height and waist circumference were measured by standardized procedures. Self-administered questionnaires described dietary habits, sleep, physical activity, body image, country of origin and general health.
RESULTS: Eighty-six percent of participants, (2600 girls, 2714 boys, mean age 18.6 years) were of Nordic origin, 86% reported no chronic health problems and 14%/19% of girls/boys were overweight or obese. Girls consumed more vegetables and fruits and fewer sweet drinks than boys, while breakfast consumption was most common in Nordic groups. Boys reported more positive answers than girls regarding body image. Nordic girls had more negative body image and higher morbidity compared with other groups.
CONCLUSION: Within this generally healthy cohort, boys were more likely to be overweight/obese than girls, although paradoxically boys were more satisfied with their appearance. Nordic girls constitute a group with particularly high risk of reporting low body self-esteem and chronic morbidity. In the longer term, the current cross-sectional data on body size, lifestyle and health will provide important baseline information for future follow-up studies of health outcomes in later life. ©2012 The Author(s)/Acta Paediatrica ©2012 Foundation Acta Paediatrica.
