title: Laboratory assessment of cardiometabolic risk in overweight and obese children.
abstract: Childhood obesity has been identified as one of the most important risk factors of developing cardiovascular diseases. The global prevalence of overweight and obesity among children shows an increasing tendency. Many of overweight or obese children will become obese adults with enhanced risk for cardiovascular diseases. Childhood obesity is often accompanied by serious consequences such as dyslipidemia, hypertension, diabetes, pro-inflammatory state and non-alcoholic fatty liver disease. Hypertension, high LDL-cholesterol and triglyceride concentrations, insulin resistance, inflammation and disturbances in adipocytokines secretion are associated with endothelial dysfunction which precedes the development of atherosclerosis. Obese children and adolescents with a clinically-proven non-alcoholic fatty liver disease, which is currently recognized as the hepatic component of metabolic syndrome, are at more severe cardiovascular risk compared with normal-weight. Obesity-related insulin resistance is highly prevalent in children and adolescents, and is associated with the increased lifetime risk of type 2 diabetes and cardiovascular disease. Adipokines contribute to obesity-atherosclerosis relationships yet among several recently discovered adipokines only few (adiponectin, resistin, chemerin, fibroblast growth factor 21, apelin) have been partly studied in obese pediatric population. The aim of this review was to describe the spectrum of cardiovascular abnormalities observed in children with overweight and obesity and the role of laboratory in the assessment of cardiometabolic risk in order to differentiate between healthy obese and those at risk to most effectively prevent progression of cardiovascular disease in childhood.
