Obesity and lipoprotein disorders are the two main pediatric diseases which are associated with later major health problems (cardiovascular, diabetes, skeletal abnormalities etc.). Nutrition dependent diseases like the former are declared to be the most serious health problems in the European region by WHO. Moreover, prevention of preventable diseases early in childhood and adolescence must be the main goal of modern medicine. The coming Symposium organized by EAROC and the Austrian Academic Institute of Nutritional Sciences deals with these topics. Our message should be “deal with lipids and obesity in the young in order to prevent cardiovascular and other problems in adulthood”.
