The prevalence of childhood obesity has increased remarkably within the past ten years with black youth disproportionately affected. Childhood obesity is linked to cardiovascular risk. Purposes of this study were to explore relationships between cardiac autonomic risk factors of heart rate variability (HRV), QT corrected (QTc) Interval duration, and Cornell voltage measures for left ventricular hypertrophy (LVH) to body mass index (BMI), relative body mass index (RBMI), and blood pressure (BP) measures, and to examine the effects of impaired glucose tolerance (IGT), hypertension, and race on these cardiac autonomic risk factors in overweight-obese adolescents.
Methods: Overweight and obese adolescents (N …
