Cardiovascular Health in Childhood A Statement for Health Professionals From the Committee on Atherosclerosis, Hypertension, and Obesity in the Young (AHOY) of the Council on Cardiovascular Disease in the Young, American Heart Association

Coronary heart disease remains the leading cause of death in the United States, responsible for close to half a million deaths each year. During the past two decades, convincing evidence has emerged that links defined risk factors in adults with an accelerated atherosclerotic process. Pathological data have shown that atherosclerosis begins in childhood and that the extent of atherosclerotic change in children and young adults can be correlated with the presence of the same risk factors identified in adults. It thus seems eminently reasonable to initiate healthful lifestyle training in childhood to promote improved cardiovascular health in adult life. The goal of this document is to provide strategies for promoting cardiovascular health that can be integrated into the comprehensive pediatric care of children. The following critical areas are reviewed: physical activity, obesity, insulin resistance and type II diabetes mellitus, hypertension, high blood cholesterol, and cigarette smoking. Background information, methods of assessment, and means for intervention are discussed for each major area. A cardiovascular health schedule has been developed to help the practitioner implement these suggestions within the framework of comprehensive pediatric care. Rather than labeling specific children as abnormal, strategies are directed toward promoting optimal cardiovascular health for all children. ### Background The health benefits associated with a physically active lifestyle in children include weight control, lower blood pressure, improved psychological well-being, and a predisposition to increased physical activity in adulthood. Increased physical activity has been associated with an increased life expectancy and decreased risk of cardiovascular disease (CVD). Healthy levels of physical fitness require regular (4 to 5 times per week) participation in activities that generate energy expenditures significantly above the resting level and ideally ≥50% to 60% of maximal exertion. Activities that result in significant energy expenditures in children may include both recreational and organized or competitive sporting activities. Physical …

Obesity, Insulin Resistance, Diabetes, and Cardiovascular Risk in Children: An American Heart Association Scientific Statement From the Atherosclerosis, Hypertension, and Obesity in the Young Committee (Council on Cardiovascular Disease in the Young) and the Diabetes Committee (Council on Nutrition, Physical Activity, and Metabolism)

This statement was reviewed by the American Diabetes Association. The recommendations contained herein are consistent with the American Diabetes Association’s Clinical Practice Recommendations. Atherosclerotic cardiovascular disease is the No. 1 killer in the adult population of Western societies,1 but the pathological processes and risk factors associated with its development have been shown to begin during childhood.2 Obesity plays a central role in the insulin resistance syndrome, which includes hyperinsulinemia, hypertension, hyperlipidemia, type 2 diabetes mellitus, and an increased risk of atherosclerotic cardiovascular disease. The incidence of type 2 diabetes reported in children has increased alarmingly.3,4 Resistance of the body to the actions of insulin results in increased production of this hormone by the pancreas and ensuing hyperinsulinemia. Obesity beginning in childhood often precedes the hyperinsulinemic state. Other components of the insulin resistance syndrome are also present in children and adolescents.5,6 An association between obesity and insulin resistance has been reported in the young, as has the link between insulin resistance, hypertension, and abnormal lipid profile. There is an increasing amount of data showing that being overweight during childhood and adolescence is significantly associated with insulin resistance, dyslipidemia, and elevated blood pressure in young adulthood. Weight loss by obese youngsters results in a decrease in insulin concentration and improvement in insulin sensitivity. Moreover, it has been determined that increased left ventricular mass, which is an independent risk factor for cardiovascular disease in adults, is present in childhood. Recent research has found that left ventricular hypertrophy is related to other risk factors, including obesity and insulin resistance in children and adolescents.7 The specifics of the transition from risk factors in childhood to diabetes and cardiovascular disease are not clear, but compelling evidence points to their association with overt disease in adults. On the basis of current knowledge …

Dietary Recommendations for Children and Adolescents: A Guide for Practitioners

Since the American Heart Association last presented nutrition guidelines for children, significant changes have occurred in the prevalence of cardiovascular risk factors and nutrition behaviors in children. Overweight has increased, whereas saturated fat and cholesterol intake have decreased, at least as percentage of total caloric intake. Better understanding of childrens cardiovascular risk status and current diet is available from national survey data. New research on the efficacy of diet intervention in children has been published. Also, increasing attention has been paid to the importance of nutrition early in life, including the fetal milieu. This scientific statement summarizes current available information on cardiovascular nutrition in children and makes recommendations for both primordial and primary prevention of cardiovascular disease beginning at a young age.

Drug Therapy of High-Risk Lipid Abnormalities in Children and Adolescents A Scientific Statement From the American Heart Association Atherosclerosis, Hypertension, and Obesity in Youth Committee, Council of Cardiovascular Disease in the Young, With the Council on Cardiovascular Nursing

Despite compliance with lifestyle recommendations, some children and adolescents with high-risk hyperlipidemia will require lipid-lowering drug therapy, particularly those with familial hypercholesterolemia. The purpose of this statement is to examine new evidence on the association of lipid abnormalities with early atherosclerosis, discuss challenges with previous guidelines, and highlight results of clinical trials with statin therapy in children and adolescents with familial hypercholesterolemia or severe hypercholesterolemia. Recommendations are provided to guide decision-making with regard to patient selection, initiation, monitoring, and maintenance of drug therapy.

Severe Obesity in Children and Adolescents: Identification, Associated Health Risks, and Treatment Approaches A Scientific Statement From the American Heart Association

Severe obesity afflicts between 4% and 6% of all youth in the United States, and the prevalence is increasing. Despite the serious immediate and long-term cardiovascular, metabolic, and other health consequences of severe pediatric obesity, current treatments are limited in effectiveness and lack widespread availability. Lifestyle modification/behavior-based treatment interventions in youth with severe obesity have demonstrated modest improvement in body mass index status, but participants have generally remained severely obese and often regained weight after the conclusion of the treatment programs. The role of medical management is minimal, because only 1 medication is currently approved for the treatment of obesity in adolescents. Bariatric surgery has generally been effective in reducing body mass index and improving cardiovascular and metabolic risk factors; however, reports of long-term outcomes are few, many youth with severe obesity do not qualify for surgery, and access is limited by lack of insurance coverage. To begin to address these challenges, the purposes of this scientific statement are to (1) provide justification for and recommend a standardized definition of severe obesity in children and adolescents; (2) raise awareness of this serious and growing problem by summarizing the current literature in this area in terms of the epidemiology and trends, associated health risks (immediate and long-term), and challenges and shortcomings of currently available treatment options; and (3) highlight areas in need of future research. Innovative behavior-based treatment, minimally invasive procedures, and medications currently under development all need to be evaluated for their efficacy and safety in this group of patients with high medical and psychosocial risks.

Long-Term Follow-Up of Patients After Coarctation of the Aorta Repair

Late cardiovascular complications after operative repair of coarctation of the aorta include systemic hypertension, premature coronary artery disease, aortic valve abnormalities, aortic aneurysm, and recoarctation. We report the outcome in 274 subjects greater-than-or-equal50 years after coarctation repair. Operative repair of simple coarctation was performed on 274 patients at the University of Minnesota Hospital between 1948 and 1976. Twenty patients (7%) died in the immediate postoperative period. Of the 254 survivors, 2 were lost to follow-up, 45 (18%) died at a mean age of 34 years, and 207 (81%) were alive greater-than-or-equal50 years after the original operation. Coronary artery disease and perioperative deaths at the time of a second cardiac operation accounted for 17 of the 45 late deaths. Predictors of survival were age at operation and blood pressure at the first postoperative visit. Of the 207 long-term survivors, 92 (48%) participated in a clinical cardiovascular evaluation. Thirty-two of the 92 subjects had systemic hypertension that was predicted by age at operation, blood pressure at the first postoperative visit, and paradoxic hypertension at operative repair. New cardiovascular abnormalities detected at follow-up evaluation included evidence of a previous myocardial infarction, cardiomyopathy, atrial fibrillation, moderate to severe left ventricular outflow tract obstruction, moderate aortic valve regurgitation, recoarctation, and ascending aortic dilation. Thus, long-term survival is significantly affected by age at operation, with the lowest mortality rates observed in patients who underwent surgery between 1 and 5 years of age. More than 1/3 of the survivors developed significant late cardiovascular abnormalities.

Relation of Body Mass Index and Insulin Resistance to Cardiovascular Risk Factors, Inflammatory Factors, and Oxidative Stress During Adolescence

Background—This study assessed the relation of fatness and insulin resistance and their interaction with cardiovascular risk factors, inflammatory factors, and oxidative stress in thin and heavy adolescents. Methods and Results—Euglycemic insulin clamp studies were performed on 295 (169 male, 126 female) adolescents (mean±SE age, 15±0.1 years). Comparisons were made between (1) heavy and thin adolescents; (2) insulin-sensitive and insulin-resistant adolescents; and (3) thin insulin-sensitive (T-IS), thin insulin-resistant (T-IR), heavy insulin-sensitive (H-IS), and heavy insulin-resistant (H-IR) adolescents. Summed z scores were used to determine clustering of risk factors (fasting insulin, triglycerides, HDL-C, and systolic blood pressure [SBP]) among the groups. SBP, triglycerides, and fasting insulin were significantly higher and HDL-C significantly lower in the heavy adolescents. Fasting insulin and triglycerides were significantly higher and HDL-C significantly lower in the insulin-resistant adolescents. Among the 4 groups, the risk factors and cluster score followed a pattern of risk as follows: T-IS<T-IR<H-IS<H-IR, with H-IR significantly greater than the other groups and showing an interaction between fatness and insulin resistance. Conclusions—These results show the significant association of both fatness and insulin resistance and their significant interaction with cardiovascular risk factors in adolescence. The finding that insulin resistance may be acting interactively with fatness suggests that interventions directed at insulin resistance in addition to weight loss may be required to alter early development of cardiovascular risk.
