title: Cardiovascular consequences of childhood obesity.
abstract: Childhood and adolescent overweight and obesity is an important and increasingly prevalent public health problem in Canada and worldwide. High adiposity in youth is indicated in clinical practice by plotting body mass index on appropriate percentile charts normed for age and sex, although waist measures might be a further tool. High adiposity can lead to adiposopathy in youth, with associated increases in inflammation and oxidative stress, changes in adipokines, and endocrinopathy. This is manifest as cardiometabolic risk factors in similar patterns to those in noted in obese adults. Obesity and cardiometabolic risk factors have been shown to be associated with vascular changes indicative of early atherosclerosis, and ventricular hypertrophy, dilation, and dysfunction. These cardiovascular consequences are evident in youth, but childhood obesity is also predictive of similar consequences in adulthood. Childhood obesity and risk factors have been shown to track into adulthood and worsen in most individuals. The result is an exponential acceleration of atherosclerosis, which can be predicted to translate into an epidemic of premature cardiovascular disease and events. A change in paradigm is needed toward preventing and curing atherosclerosis and not just preventing cardiovascular disease. This would necessarily create an imperative for preventing and treating childhood obesity. Urgent attention, policy, and action are needed to avoid the enormous future social and health care costs associated with the cardiovascular consequences of obesity in youth.
