Regular articleDoes early physical activity predict body fat change throughout childhood? Lynn L. Moore D.Sc. a Section of Preventive Medicine and Epidemiology, Boston University School of Medicine, Boston, MA 02118, USA Available online 26 April 2003. AbstractBackgroundDeclining levels of physical activity in the population at large may be responsible in part for the rising rates of childhood obesity. Studies to date, however, have not consistently demonstrated such a protective effect. We used longitudinal data from the Framingham Children's Study (FCS) to address this important question. MethodsWe used 8 years of activity monitoring (Caltrac electronic motion sensors) and repeated anthropometry measures for 103 children to examine the effect of activity on body fat change from preschool to early adolescence. Longitudinal data analysis methods were employed to account for the use of repeated measures on these children. ResultsChildren in the highest tertile of average daily activity from ages 4 to 11 years had consistently smaller gains in BMI, triceps, and sum of five skinfolds throughout childhood. By early adolescence (age 11), the sum of five skinfolds was 95.1, 94.5, and 74.1 for the low, middle, and high tertiles of activity, respectively (P for TREND = 0.045). This protective effect of activity was evident for both girls and boys. ConclusionThis longitudinal study adds strong support for the hypothesis that higher levels of physical activity during childhood lead to the acquisition of less body fat by the time of early adolescence.

 "A foolish faith in authority is the worst enemy of truth." -- Albert Einstein, letter to a friend, 1901 "I know of no safe depository of the ultimate powers of the society but the people themselves, and if we think them not enlightened enough to exercise control with a wholesome discretion, the remedy is not to take it from them, but to inform their discretion by education." -- Thomas Jefferson, letter to William C. Jarvis, September 28, 1820 "What's the point of vaccination if it doesn't protect you from the unvaccinated?" -- Sandy Gottstein "Who gets to decide what the greater good is and how many will be sacrificed to it?" -- Sandy Gottstein |
