The purpose of the study was to investigate the longitudinal relationship between physical activity and clustering of some cardiovascular disease (CVD) risk factors after 1-y follow-up.
The sample comprised 704 males and 770 females between the ages of 8 to 15 y. Clustering was defined as belonging to one or more sex and age-specific “high-risk” quartiles for biological risk factors. The longitudinal relationships were analyzed with multilevel analysis.
There was no longitudinal significant relationship between physical activity and individual biological risk factors. When biological risk factor clustering was considered, however, there was a significant longitudinal relationship with physical activity.
It can be concluded that even at a young age, physical activity can play an important role in developing a healthy lifestyle profile.
