Background: Schools are an ideal setting in which to involve children in research. Yet for investigators wishing to work in these settings, there are few method papers providing insights into working efficiently in this setting. Objective: The aim of this paper is to describe the five strategies used to increase response rates, data quality and…

The current state of physical fitness in American youth is unknown. While evidence exists that obesity levels are increasing in children and youth, data on declines in physical fitness measures (i.e., cardiorespiratory and musculoskeletal fitness) are lacking. Tracking of physical fitness components has been poorly done. Surveillance of behaviors…

The present analysis aimed to describe the degree of tracking of physical activity over an 8-year follow-up period among a cohort of 557 adolescents in western Norway (13 years of age at baseline). Frequency and time spent in leisure-time physical activity were assessed at ages 13, 14, 15, 16, 18, 19 and 21 years through self-report…
