Although it is rare for cardiovascular disease (CVD) to manifest in children and adolescents, risk factors and behaviors do start in childhood. Evidence indicates that reducing risk can slow the progression of CVD; therefore, the National Heart, Lung, and Blood Institute (NHBLI) Expert Panel on Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents developed guidelines to help health care professionals promote cardiovascular health and to identify and manage risk factors in children and adolescents. These guidelines were based on evidence that atherosclerosis begins, and its risk factors can be identified, in childhood; that atherosclerosis development and progression are associated with these risk factors; that risk factors track from childhood into adulthood; and that there are options for managing these risk factors.

Prevention goals in young persons should be separate from prevention goals in older persons in whom atherosclerosis is well established. Historically, preventing the development of risk factors and preventing CVD through effective management of risk factors have been the two main goals in young persons. Research supports the theory that childhood populations with lower levels of cardiovascular risk factors will have less atherosclerosis and CVD as adults.

Table 1 provides the integrated cardiovascular health schedule.

BMI = body mass index; CHILD = cardiovascular health integrated lifestyle diet; CVD = cardiovascular disease; HDL = high-density lipoprotein.

Lipid and lipoprotein levels in childhood are predictive of levels in adulthood, with the strongest relationship occurring between levels in late childhood and at age 20 to 40 years. Table 2 lists normal lipid and lipoprotein distributions in children and adolescents. Total and low-density lipoprotein (LDL) cholesterol levels can decrease by 10 to 20 percent or more during puberty. Based on this, a stable time for lipid evaluation would be 10 years of age, which is before puberty in most children.

Acceptable, Borderline-High, and High Plasma Lipid, Lipoprotein, and Apolipoprotein Concentrations for Children and Adolescents

Category		Low (mg per dL)*	Acceptable (mg per dL)	Borderline-high (mg per dL)*	High (mg per dL)*
Total cholesterol		—	< 170	170 to 199	≥ 200
LDL cholesterol		—	< 110	110 to 129	≥ 130

HDL cholesterol		< 40	> 45	40 to 45	—
Apolipoprotein A-1		< 115	> 120	115 to 120	—

note: Values for plasma lipid and lipoprotein levels are from the National Cholesterol Education Program Expert Panel on Cholesterol Levels in Children. Non-HDL cholesterol values from the Bogalusa Heart Study are equivalent to the National Cholesterol Education Program Pediatric Panel cut points for LDL cholesterol. Values for plasma apolipoprotein B and apolipoprotein A-1 are from the National Health and Nutrition Examination Survey III. Note that values shown are in mg per dL; to convert to SI units, divide the results for total cholesterol, LDL cholesterol, HDL cholesterol, and non-HDL cholesterol by 38.6; for triglycerides, divide by 88.6.

HDL = high-density lipoprotein; LDL = low-density lipoprotein.

*—Low cut points for HDL cholesterol and apolipoprotein A-1 represent approximately the 10th percentile. The cut points for high and borderline-high represent approximately the 95th and 75th percentiles, respectively.

HDL = high-density lipoprotein; LDL = low-density lipoprotein.

To reduce total and LDL cholesterol levels, children should eat a diet made up of 25 to 30 percent of calories from fat, with less than 10 percent from saturated fat, and less than 300 mg of cholesterol per day (e.g., CHILD-1 [cardiovascular health integrated lifestyle diet]). Some evidence indicates that this type of diet also reduces total and LDL cholesterol levels if started in infancy and continued through adolescence. A diet that has no more than 7 percent of calories from saturated fat and less than 200 mg of cholesterol per day (CHILD-2-LDL) has been shown to decrease LDL cholesterol levels in children diagnosed with hypercholesterolemia and an elevated LDL cholesterol level. Table 3 briefly summarizes the various recommended diets.

†—Consideration of drug therapy is based on the average of at least two fasting lipid profiles, obtained at least 2 weeks but no more than 3 months apart.

¶—If the child is obese, nutrition therapy should include calorie restriction and increased activity beyond that recommended for all children.

In children with familial hypercholesterolemia, up to 20 g per day of a dietary supplement (e.g., plant sterol or stanol esters) can augment LDL cholesterol–lowering effects in the short term. Long-term trials have not been performed; therefore, these types of dietary supplements are typically used only for children in whom LDL cholesterol goals cannot be achieved with dietary therapy alone, with the hope that they may lower LDL cholesterol levels enough to avoid using medication. Consuming a diet with fewer simple carbohydrates (and with more complex carbohydrates and less saturated fat) and losing weight are associated with lower triglyceride levels. Children with elevated triglyceride levels and obesity should eat fewer calories, with the CHILD-2–TG being the recommended diet. It is also important that these children get more physical activity.

Table 3 provides the recommendations for pharmacologic treatment of dyslipidemia.
