Influence of cholesterol screening and nutritional counseling in reducing cholesterol levels in children. The American Heart Association.

The purpose of this study was to determine whether cholesterol screening and nutritional counseling can reduce cholesterol concentrations in populations of otherwise unrecognized hypercholesterolemic children. A large pediatric practice in Parma Heights, Ohio, has conducted cholesterol surveillance of children over 2 years of age since 1986. The importance of cholesterol and other recognized risk factors for the progression of atherosclerosis is discussed with all families, and the American Heart Association's Step-One diet is recommended. The present study examines data from a cohort of 894 children (473 boys, 421 girls) who had cholesterol concentrations above 185 mg/dL (4.79 mmol/L) (the 90th percentile) at baseline and, after counseling, had a repeat measurement an average of 2.2 years later. Their mean ages were 7 years at the first testing and 9.2 years at the second. Children who had cholesterol concentrations above 200 mg/dL (5.18 mmol/L) (the 95th percentile) had lipoprotein profiles done, and if their LDL cholesterol exceeded 130 mg/dL (3.37 mmol/L) (the 95th percentile), they were referred to a nutritionist, and family members were advised to have their blood lipids analyzed. Mean cholesterol concentration for all 894 children over this time period decreased by 9.4% (19.5 mg/dL [0.51 mmol/L]; 95% CI = 17.5 mg/dL [0.45 mmol/L] to 21.5 mg/dL [0.56 mmol/L]; P < 0.001). A similar decrease of 8.6% (16.6 mg/dL [0.43 mmol/L); 95% CI = 14.0 mg/dL [0.36 mmol/L] to 19.3 mg/dL [0.50 mmol/L); P < 0.001) was observed for the 463 children who had initial cholesterol concentrations between 185 and 200 mg/dL (4.79 and 5.18 mmol/L) and who therefore received a less intense intervention. Cholesterol concentrations in groups of otherwise unidentified hypercholesterolemic children can be significantly reduced as a result of cholesterol screening and nutritional counseling in a pediatric practice setting.
