title: Weight status, physical activity, and vascular health in 9- to 12-year-old children.
abstract: BACKGROUND
  The purpose of this study was to determine the independent and joint association of weight status and physical activity on resting blood pressure and C-reactive protein in children.
  
  
  METHODS
  Participants were 174 (71 males, 103 females) children (mean age = 10.5 ± 0.4 yrs). Physical activity was self-reported, body mass index was calculated from measured height and body mass, and blood pressure was measured according to standard procedures. A subset of 91 children had C-reactive protein measured by fingerstick blood sample. Four weight/physical activity groups were created by cross tabulation of weight status classification and physical activity level.
  
  
  RESULTS
  The prevalence of low physical activity (< 5 days/wk moderate-vigorous activity) did not differ between overweight and normal weight children (50%). Physical activity was not correlated with C-reactive protein (r = 0.01; P = 0.91) and C-reactive protein was not significantly different between physical activity groups (P = 0.87). Physical activity did not modify the difference in blood pressure or C-reactive protein within weight categories.
  
  
  CONCLUSIONS
  Fatness (specifically overweight and obesity), but not physical activity, was shown to be associated with blood pressure and C-reactive protein levels in children. Physical activity did not attenuate blood pressure or C-reactive protein in overweight and obese children.
