Well-being, Body Perception and Weight Status in Young Swedes – The Grow Up Studies

Well-being, Body Perception and Weight Status in Young Swedes – The Grow Up Studies

weight status in an adolescent Swedish population growing up in a changing society with increasing obesity prevalence. The major aims were to document secular changes in, and investigate factors related to, well-being. A well-being scale was adopted for use in adolescents and three childhood BMI classification systems for identifying children at risk of overweight and obesity were assessed.
About 5000 Gothenburg-area students in their final year of high-school (mean age 18.6 years) were included in the Grow Up 1990 birth cohort study. Height and weight were measured and information about well-being, body perception and lifestyle were self-reported. Health records from birth to the final school grade were obtained. Well-being in the Grow Up 1974 birth cohort served as comparison.
Overweight, including obesity, was more prevalent in boys (19%) than in girls (13.4%). However, half of the boys, compared to one-third of the girls, were often satisfied with their body size. The well-being scale developed in this thesis, consisting of five dimensions (mood, self-esteem, physical condition, energy and stress balance), revealed that boys experienced higher well-being than girls across all dimensions. Objective body measurements accounted for less of the well-being variance than sub-jective satisfaction with body size. Regular physical activity, resilience and a happy event during the last year were positively related to well-being, whereas reporting little sleep, dissatisfaction with body size and a sad event during the last year were nega-tively related to well-being. Well-being was lower, and in particular stress levels were higher, in the later-born cohort than in the 1974 birth cohort. These differences were not explained by the shift in weight status. Girls, however, reported higher self-esteem in the later-born cohort, compared to girls born in 1974. The childhood BMI classifi-cation systems varied in ability to predict overweight and obesity at age 18, related to weight status at age 10, although they all mainly correctly identified those without overweight or obesity.
This thesis documents interrelations among well-being, body satisfaction and weight status in Swedish adolescents. These studies identified important factors and interrelations to consider when designing interventions to promote well-being and physical health in adolescents.
