  • Anthropometric and physiologic descriptors at baseline. No significant differences between intervention and control participants. HDL, high-density lipoprotein; LDL, low-density lipoprotein.

  • a High or borderline was defined as systolic or diastolic blood pressure >the 90th percentile for age, sex, and height.
