Background: Hypercholesterolemia is a risk factor of cardiovascular diseases and metabolic syndrome. Cholesterol level in childhood is related to the development of cardiovascular diseases in adulthood. This study aimed to
investigate cholesterol levels of first grade students in elementary school, to analyze the relationship between the children’s cholesterol levels and those of parents’ and to evaluate the factors influencing children’s cholesterol levels.
Methods: In 2004, a sample of 108 first-graders in elementary school in Gwacheon city and their 216 parents
were included in this study. Height, weight, body mass index, waist and hip circumference and blood pressure were measured and bio-chemical data were obtained. The children’s birth weight, eating habits, physical activity, occupation, educational background, married status, mean monthly income of each family were obtained by questionnaire.
Results: The correlation coefficient between children’s cholesterol and fathers’ cholesterol was 0.331 (P＜0.001).
The correlation coefficient between children’s cholesterol and mothers’ cholesterol was 0.364 (P＜0.001). The mean
total cholesterol level in children differed significantly according to mother’s smoking status, mother’s overeating
due to stress and mother’s diet restriction tendency for weight control. In multiple linear regression analysis
of children’s cholesterol as dependent variable, the explanation power (R2) of the model including children’s sex,
father’s age and cholesterol levels, mother’s age and cholesterol levels was 0.281. The explanation power (R2)
of the other model including variables of the previous model and children’s fruit consumption, parent’s eating
out tendency, mother’s smoking status, mother’s other behavior during mealtime, mother’s overeating due to
stress and mother’s diet restriction tendency for weight control was 0.388. In final model, only the parent’s
cholesterol levels had significant effect on children’s cholesterol levels.
Conclusion: It was parent’s cholesterol level that affected significantly on the children’s cholesterol level.
