Description

411 adolescents born in 1978 or 1979 in two socioeconomically different cities are included in the study. Collection of the material has occurred three times for each youth, at 15, 17 and 20 years of age. 103 boys and 106 girls in Uppsala, and 90 boys and 112 girls in Trollhättan participated in the study.

In Part 1 of the longitudinal study, adolescents were examined at 15, 17 and 20.5 years of age. Lifestyle factors such as nutrition, physical activity, smoking and alcohol habits were studied to later be able to determine whether these are associated with health problems in adulthood such as cardiovascular disease, obesity, osteoporosis, diabetes and cancer. The idea is also to analyze whether differences in adolescents’ socio-economic background correlates with lifestyle factors, health and development of disease in adulthood.

Serum and in some cases whole blood from 15, 17 and 20.5 years of age are stored in Uppsala Biobank, in addition to measurement data and questionnaire responses.

There is an opportunity to continue with Part 2 of the study, since the adolescents are now more than 3
