title: Physical activity, stress, and metabolic risk score in 8- to 18-year-old boys.
abstract: BACKGROUND
  We examined whether physical activity modifies the relationship between stress and the metabolic risk score in 8- to 18-year-old males (n = 37).
  
  
  METHODS
  Physical activity (PA) and television (TV)/videogame (VG) use were assessed via accelerometer and questionnaire, respectively. Stress was determined from self-report measures. A metabolic risk score (MRS) was created by summing age-standardized residuals for waist circumference, mean arterial pressure, glycosylated hemoglobin, and high-density lipoprotein cholesterol.
  
  
  RESULTS
  Correlations between PA and MRS were low (r < -.13), and TV and VG were moderately associated with MRS (r = .39 and .43, respectively). Correlations between stress-related variables and MRS ranged from r = .19 to .64. After partitioning by PA, significant correlations were observed in the low PA group between school- and sports-related self-esteem and anxiety with the MRS.
  
  
  CONCLUSIONS
  The results provide suggestive evidence that PA might modify the relationship between stress and MRS in male adolescents.
