Abstract

The objective was to determine the effects of the National Cholesterol Education Program (NCEP) step 11 diet on LDL and HDL particle size in dyslipidaemic adolescents. Forty-four dyslipidaemic adolescents, aged 10-18 years, participated in this case-control study. The control diet was a diet similar to what most Tehranian adolescents eat. NCEP step 11 diet was a diet with 30 % of energy as total fat, less than 7 % saturated fat, less than 200 mg cholesterol/d, less than 15 % of energy as MUFA and less than 10 % as PUFA. Lipoprotein particle size was the major outcome variable, which was measured after 3 months of intervention. Comparison was made by the repeated measurement ANOVA. The mean BMI was 26 center dot 3 (SD 4 center dot 2) kg/m(2). There were no significant changes in weight or physical activity in the two groups during the study. The NCEP diet resulted in higher reduction in total cholesterol (- 13 (SD 4) v. -2 (SD 0 center dot 3) mg/dl, P<0 center dot 001) and LDL (-9 (SD 2) v. 3 (SD 0 center dot 6) mg/dl, P<0 center dot 01), and higher increase in size of the LDL (1 center dot 7 (SD 0 center dot 4) v. 0 center dot 1 (SD 0 center dot 4) nanometer, P<0 center dot 001). HDL particle size did not change significantly. NCEP step 11 diet had a favourable effect on the LDL particle size. The related mechanism needs to be studied in future experimental designs.
