The Cardiovascular Risk in Young Finns Study (YFS) is one of the largest follow-up studies into cardiovascular risk from childhood to adulthood. The main aim is to determine the contribution made by childhood lifestyle, biological, and psychological measures to the risk of cardiovascular diseases in adulthood. Over 3500 children and adolescents participated in the first cross-sectional survey that was conducted in 1980. In the latest follow-up in 2011/12 a total of 2,063 subjects were examined (57% of the original cohort). Irinja Lounassalo'’s study for a doctoral thesis is part of the YFS. The study aims to discover the role and meaning of physical activity (PA) in healthy lifestyle and find out whether PA is a gateway to healthier lifestyle. The objective is to examine whether childhood and adolescence PA history predicts other health-protective behaviors (healthy diet, adequate sleeping and reasonable television viewing) in young and mid-adulthood. Also the associations between changes in PA and changes in diet, sleeping and television viewing from childhood to mid-adulthood will be studied. PA history is determined here as different PA trajectories from childhood to adulthood. Latent class growth modeling is used for identifying the diverse trajectories of PA.
