    Sammanfattning : The overall aim of this thesis was to increase the knowledge about different aspects of body size and physical activity among Swedish children and young adults. Specific aims were: (i) to investigate how BMI-distributions (BMI=Body Mass Index) have changed among Swedish children over a 12 year period, (ii) to study effects of pre- and postnatal growth on body size and body composition in adolescence, (iii) to study associations between parents and children s physical activity, and (iv) to investigate genetic contributions to physical activity behavior.

    Sammanfattning : In recent developmental research, sleep-wake patterns and preferences, in other words Morningness-Eveningness, have been shown to be related to various kinds of problem behavior. Previous research on adolescents has demonstrated that individuals with a sleep-wake preference toward staying up late in the evening and arising late in the morning (i.e. LÄS MER
