Abstract
In connection with a survey of child nutrition in Finland a study was carried out on the serum cholesterol concentration in childhood and its relationship to dietary and other variables. The material consisted of 1496 children ages 5,9, and 13 years from 14 local districts in Finland. Total cholesterol was determined from nonfasted venous serum samples by a modification of the p-toluenesulfonic acid reaction. Food consumption was investigated by the 24-hr recall method and nutrient intakes determined from these results using food composition tables. For analysis, children in each age group were classified into low, medium, and high cholesterol groups. The serum cholesterol concentrations of the 5, 9, and 13 year olds were 6.03 ± 1.03, 6.16 ± 1.04, and 6.08 ± 1.01 mmole/liter (233 ± 40, 238 ± 40, and 235 ± 39mg/100 ml), respectively. Of the children 10% had serum cholesterol concentrations of 7.4 mmole/liter (286 mg/100 ml) or more. Serum cholesterol concentration was not correlated with sex, relative body weight, or systolic or diastolic blood pressure. High cholesterol concentrations appeared to be associated with traditional dietary habits and especially with a high proportion of saturated fats in the diet.
