Obesity and postprandial lipemia in adolescents: risk factors for cardiovascular disease

Abstract

In the last 50 years, obesity has become a global epidemic and is one of the main public health problems in many parts of the world. Adolescence is a critical period regarding weight control. The factors determining obesity include a complex group of interrelated biological, behavioral and environmental factors which reinforce each other. In children and adolescents, obesity is associated with premature cardiovascular diseases, diabetes mellitus type 2, acanthosis nigricans, respiratory and skeletal muscle problems, as well as psychological problems. The clinical manifestations of cardiovascular disease begin in middle age. Nevertheless, studies indicate that the atherosclerotic process begins to develop during childhood. Postprandial hyperlipemia is a physiological process that occurs several times a day after the complete absorption of a diet including lipids and has been suggested as a risk factor for coronary heart disease (CHD). New study areas include the effects of different fatty acids, lipid sources (endogenous and exogenous), and the effect ingesting alcoholic beverages during meals. Given the evidence that postprandial lipidemia is an independent risk factor for CHD, it is vital to establish normative values for children and adolescents such that more effective and efficient preventive and therapeutic measures can be adopted.
