This clinical report replaces the 1998 policy statement from the American Academy of Pediatrics on cholesterol in childhood, which has been retired. This report has taken on new urgency given the current epidemic of childhood obesity with the subsequent increasing risk of type 2 diabetes mellitus, hypertension, and cardiovascular disease in older children and adults. The approach to screening children and adolescents with a fasting lipid profile remains a targeted approach. Overweight children belong to a special risk category of children and are in need of cholesterol screening regardless of family history or other risk factors. This report reemphasizes the need for prevention of cardiovascular disease by following Dietary Guidelines for Americans and increasing physical activity and also includes a review of the pharmacologic agents and indications for treating dyslipidemia in children. Pediatrics 2008;122:198-208 INTRODUCTION Cardiovascular disease (CVD) is the leading cause of death and morbidity in the United States. 1 Most of the clinical burden of CVD occurs in adulthood. However, research over the last 40 years has increasingly indicated that the process of atherosclerotic CVD begins early in life and is progressive throughout the life span. 2 It has also become clear that there is an important genetic component to the disease process that produces susceptibility but that environmental factors, such as diet and physical activity, are equally important in determining the course of the disease process.This statement replaces the outdated 1998 American Academy of Pediatrics (AAP) policy statement "Cholesterol in Childhood," which has been retired. 3 New data emphasize the negative effects of excess dietary intake of saturated and trans fats and cholesterol as well as the effect of carbohydrate intake, the obesity epidemic, the metabolic/insulin-resistance syndrome, and the decreased level of physical activity and fitness on the risk of adult-onset CVD. In addition, more data are now available on the safety and efficiency of pharmacologic agents used to treat dyslipidemia. Most of these data were not available at the time of the previous statement.A number of studies have identified potential risk factors for adult CVD. 4 The strongest risk factors include a high concentration of low-density lipoprotein (LDL), a low concentration of high-density lipoprotein (HDL), elevated blood pressure, type 1 or 2 diabetes mellitus, cigarette smoking, and obesity. Research in children and adolescents has demonstrated that some of these risk factors may be present at a young age, 5 and pediatricians must initiate the lifelong approach to prevention of CVD in their patients. The focus of this report is on improving lipid and lipoprotein concentrations during childhood and adolescence to lower the lifelong risk of CVD. The current obesity epidemic among children has increased the need for pediatric health care professionals to be knowledgeable of the risk factors for CVD and to implement the changes recommended in...
