Tracking of overweight from mid-adolescence into adulthood: consistent patterns across socio-economic groups.

Socially differentiated tracking of health and health behaviours may contribute to health inequalities in adulthood. The modifying effect of socio-economic position on the tracking of overweight from mid-adolescence (age 15 years) into adulthood (age 27 years) was assessed in a randomly sampled Danish cohort (n = 561). The tracking was studied by prediction analyses conducted by logistic regression analyses. Strong tracking patterns were found to be independent of socio-economic background.
