Influence of dietary intervention on growth in children with hypercholesterolaemia

Abstract

Aim: To determine whether a moderately reduced fat diet affects longitudinal growth in children with hypercholesterolaemia with a mean duration of 7.42 +/- 1.93 y.

Methods: Subjects with hypercholesterolaemia, total cholesterol above 5.18 mmol/L and LDL-cholesterol above 3.49 mmol/L (n = 144; 69 males and 75 females) from 2 to 13 y of age were studied. Patients were seen in our outpatient department for regular health check-ups. Weight and height were measured every year. At the same time, cholesterol, triglycerides, LDL-C, HDL-C, A-apoprotein and B-apoprotein levels were analysed. Furthermore, degrees of compliance at 1 mo, 6 mo and each year after starting the dietary treatment were determined.

Results: No significant change in height or weight was found after fat restriction. In contrast, significant reductions in total cholesterol, LDL cholesterol and B-apoprotein levels of 19%, 24% and 14%, respectively, were detected. Finally, no significant differences were seen in HDL-cholesterol, A-apoprotein or triglycerides.

Conclusions: These data support the hypothesis that growth is not influenced by moderate fat restriction in healthy children who otherwise have normal nutrition.
