[Results of a 2-year intervention for the modification of atherosclerosis precursors in school children].

801 children aged 10-11 years were examined in 1984, before an allocation in two groups (intervention vs. control). The scope of the intervention was to modify mean values of blood pressure, total cholesterol and smoking through relevant modification of knowledge and behavior. An intermediate assessment, conducted 2 years after the first exam, showed better knowledge regarding cardiovascular diseases and more sport practice in the intervention group, although smoking habits were only slightly modified. Diet, body weight, blood pressure and blood lipid levels did not show any significative differences. The study is now ongoing.
