Table 2 Characteristics of clinical parameters and cardiovascular risk score of the study cohort stratified by level of physical activity (low to moderate versus high).

From: Association between Physical Activity and Cardiovascular Risk in Chinese Youth Independent of Age and Pubertal Stage

  1. Data marked with ψ were presented as frequencies (%), all others were presented as means (standard deviations).
  2. # The cutoff threshold was identified using the approach of Walter et al [24]
  3. Overweight and obesity were defined respectively by body mass index > 85th and 95th percentiles (age and sex specific based on a local population survey [23]).
  4. * Cardiovascular Score = Sum of components' z score: components of cardiovascular risk score include z-score of sex-specific, age-adjusted waist circumference, systolic blood pressure (also height-adjusted), fasting plasma glucose, triglyceride and total cholesterol (TC)/high-density lipoprotein cholesterol (HDL-C) ratio.
