The mean age of the studied children was 8.27 years, 55.5% were male The weight measurements were performed on a digital anthropometric scale. The body mass index was calculated for each child and the Food Frequency Questionnaire was applied. The peripheral blood was collected for lipid profile analysis. Stata 12.0 statistical package was used to analyze the data, considering a significance level of p < 0.05.
Results: The prevalence of hypercholesterolemia based on the serum cholesterol from low density lipoprotein fraction was 14.6%. It was observed that children in the group who consumed the lower difference of risky and protective foods on a daily basis were not less likely to have a high cholesterol from low density lipoprotein level as a criterion for hypercholesterolemia (p = 0.218).
