Abstract

BACKGROUND: Based on the knowledge on beneficial effects of physical activity (PA) on health and fitness, we hypothesized that PA in adolescence is related to high education and socio-economic position (SEP) in adulthood. Improved school performance may mediate the hypothesized relationship. METHODS: The Adolescent Health and Lifestyle Surveys (AHLS), collected biennially in 1981-89 (baseline) and representing 14- and 16-year-old Finns were individually linked with national registries of the highest educational level and SEP. Of the sample, 10 498 (78%) responded the surveys and were followed till the end of 2001 (age group of 28-38 years). Multinomial logistic regression analysis was used to study the associations between the outcomes (highest attained educational level, SEP) and PA (sports clubs, spontaneous, intensity). RESULTS: Participating in sports club or spontaneous PA and practicing with high intensity in adolescence were associated with higher educational levels and SEP in adulthood. Childhood socio-economic background only slightly influenced the associations and largely, PA predicted the outcomes independently of background. Particularly among girls, school performance partly accounted for the associations between PA and the highest educational level and the highest SEP. CONCLUSIONS: Participation in PA in adolescence and particularly its high intensity, predicts higher educational levels and SEP in early middle age. School performance to some degree mediates the impact of PA. PA behaviours in adolescence-or possibilities to participate in PA-are a potential mechanism in generating better health of higher socio-economic and educational groups in adult age.
