AbstractLifestyle changes are important factors for managing dyslipidemia before considering blood lipid-lowering drugs. However, genetic factors can influence the response outcome.We aimed to determine a dyslipidemia management strategy in obese adolescents.: A total of 60 dyslipidemic obese adolescents received physical exercise and the NCEP step II diet for 28 days. Apolipoprotein E (apo E) genotypes and blood lipid levels were compared before and after interventions.The apoApo E alleles might influence improvement in lipid profiles after diet and exercise interventions. These results could inform personalized dyslipidemia management in obese adolescents, to determine which subjects would benefit from blood lipid-lowering drugs.
