Influence of the Mediterranean diet on carotid intima–media thickness in hypercholesterolaemic children: A 12-month intervention study

Abstract Background and aims The Mediterranean diet has been recognised as having a protective role on the cardiovascular system due to its low lipid and high antioxidant content. Lipid profile and oxidant status represent two important risk factors related to endothelial dysfunction, even at early stages of cardiovascular diseases. The aim of the study was to evaluate the influence of a 12-month Mediterranean diet on the variation of lipid profile and carotid intima–media thickness (cIMT) in pre-pubertal hypercholesterolaemic children. Methods and results We performed a cross-sectional study comparing lipid profile and cIMT in a group of 68 pre-pubertal children (36 with hypercholesterolaemia and 32 controls). In addition, in the hypercholesterolaemic children a 12-month intervention programme with a Mediterranean diet was started to evaluate the variation of lipid profile and cIMT. At baseline, hypercholesterolaemic children showed a significantly higher cIMT (both right and left carotid artery) compared to controls (both p p p Conclusion The Mediterranean diet represents a valid approach in the treatment of hypercholesterolaemia even during childhood.
