Abstract
Six to seven per cent of school children 6 to 14 years of age may have serum cholesterol concentrations above 220 mg. per 100 ml. by the Huang method. This is especially characteristic of children 9, 10, and 11 years old, and is less frequent in children who are younger or older. The serum cholesterol does not differ according to sex; it is not correlated with serum protein-bound iodine, body surface area, beta or pre-beta lipoprotein percentages, or triglyceride values. There is a low but significant correlation of the serum cholesterol values of the parents with those of their children. Using the Harlan nomogram, the hypercholesterolemic children may be classified as Frederickson Types II or III.
