RECOMMENDATIONS

MAJOR RECOMMENDATIONS

TABLE: Cardiovascular Risk Profile

Assessment: Risk Factors/Risk Indicators Recommendations
Family history Integrate with well-child care; update regularly: multigenerational family history of cardiovascular disease (CVD), diabetes, obesity, hypertension, dyslipidemia, cigarette smoking (Kavey et al., 2003; Williams et al., 2002)
Lipids and lipoproteins: levels of concern (National Cholesterol Education Program, 1991; Kavey et al., 2003)  

Total cholesterol: borderline, >170 milligrams per deciliter (mg/dL); elevated, >200 mg/dL

Targeted screening of fasting lipids in children ≥2 years of age with family history of premature CVD, diabetes, dyslipidemia; screen children with other risk factors (i.e., overweight) and children whose family history of CVD, diabetes, and/or dyslipidemia is unknown (National Cholesterol Education Program, 1991; Kavey et al., 2003; McCrindle et al., 2007)

Low-density lipoprotein cholesterol (LDL-C): borderline, >110 mg/dL; elevated, >130 mg/dL

Triglycerides: >110 mg/dL

High-density lipoprotein cholesterol (HDL-C): <40 mg/dL

Note: LDL-C should be <100 mg/dL in children with diabetes

Averaged results of 2 fasting lipid profiles guide treatment decisions (see Table below)
Systolic and diastolic blood pressure (SBP and DBP): levels of concern  

SBP and DBP >90th percentile for age, gender, and height

BP measurements should be interpreted on the basis of age, gender, and height (National High Blood Pressure Education Program Working Group, 2004) (BP percentiles are available at http://www.nhlbi.nih.gov/guidelines/hypertension/child_tbl.pdf)

Note: Hypertension is defined as average SBP and/or DBP that is >95th percentile for gender, age, and height on >3 separate occasions; BP levels that are >90th percentile and <95th percentile are now termed prehypertension (National High Blood Pressure Education Program Working Group, 2004)

BP should be measured beginning at age 3 years and in accordance with recent guidelines (National High Blood Pressure Education Program Working Group, 2004) (see Table below for clinical management)
Body size: levels of concern  

Risk of overweight, body mass index (BMI) >85th percentile; overweight, >95th percentile

Body size should be charted by BMI (norms for BMI percentiles are available at http://www.cdc.gov/growthcharts)
Health behaviors: areas of concern

Tobacco use and/or exposure to second-hand smoke: any

Physical activity: <60 minutes/day moderate to vigorous physical activity; >2 hours/day sedentary activities

Dietary intake: excess sugar, excess soft drinks and fruit juices, saturated fat, and salt; <5 servings/day of fruits and vegetables; <3 servings/day of dairy; <6 servings/day of whole grain and grain products; skipping breakfast; few family meals; large portion sizes

Assess health behaviors at every visit, including tobacco use and exposure to second-hand smoke by child/family/peers; advise participation in 60 minutes/day moderate to vigorous physical activity such as active outdoor play, walking/biking to school and sports activities, active school recess; resistance training (10-15 repetitions at moderate intensity) can be combined with aerobic activity in an overall activity program for older school-age children and adolescents; assess patterns of dietary intake at every visit; match energy intake with energy needs for growth and developmental processes (Kavey et al., 2003; Williams et al., 2002; Gidding et al., 2005; Council on Sports Medicine and Fitness, 2006)

TABLE: Guidelines for CVD Risk Reduction Intervention for Children and Adolescents With Identified Risk*

Risk Intervention Recommendations
Blood cholesterol management If LDL-C is above goals, initiate additional therapeutic lifestyle changes, including diet (<7% of calories from saturated fat; <200 mg cholesterol/day), in conjunction with a trained dietitian.

Goals

Consider LDL-C–lowering dietary options (increase total dietary fiber with emphasis on viscous fibers (i.e., oat bran, pectin) by using age (in years) plus 5 g up to age 20, when the total remains at 25 g/day (William, Bollella, & Wynder, 1995) in conjunction with a trained dietitian.

LDL-C <160 mg/dL (<130 mg/dL is better)

Emphasize weight management and increased physical activity.

For patients with diabetes, LDL-C <100 mg/dL

If LDL-C is persistently above goals, evaluate for secondary causes (thyroid-stimulating hormone, liver function tests, renal function tests, urinalysis).

Consider pharmacological therapy for individuals with LDL-C >190 milligrams per deciliter (mg/dL) with no other risk factors for CVD; or >160 mg/dL with other risk factors present (BP elevation, diabetes, overweight, strong family history of premature CVD); or if treatment goals not realized after adequate trial of therapeutic lifestyle change.
Other lipids and lipoproteins Pharmacological intervention for dyslipidemia should be accomplished in collaboration with a physician experienced in treatment of disorders of cholesterol in pediatric patients.

Goals

Elevated fasting triglycerides and reduced HDL-C are often seen in the context of overweight with insulin resistance. Therapeutic lifestyle change should include weight management with appropriate energy intake and expenditure. Decrease intake of energy-dense snack food high in sugar and sugar beverages such as soft drinks, fruit juices, and sports drinks.

Fasting triglycerides <150 mg/dL

If fasting triglycerides are persistently elevated, evaluate for secondary causes such as diabetes, thyroid disease, renal disease, and alcohol abuse. No pharmacological interventions are recommended in children for isolated elevation of fasting triglycerides unless this is very marked (treatment may be initiated at triglycerides >400 mg/dL to protect against postprandial triglycerides of ≥1000 mg/dL, which may be associated with an increased risk of pancreatitis).

HDL-C >35 mg/dL

 
Management of BP elevation  

Goal

Promote achievement of appropriate weight.

SBP and DBP <95th percentile for age, sex, and height; with comorbidities, <90th percentile for age, gender, and height

Reduce sodium in the diet. Emphasize increased consumption of fruits and vegetables.
  If BP is persistently >95th percentile, consider secondary causes (i.e., renal disease, coarctation of the aorta).

Consider pharmacological therapy for individuals >95th percentile if lifestyle modification brings no improvement and there is evidence of target organ changes (left ventricular hypertrophy, microalbuminuria, renal vascular abnormalities). Start BP medication individualized to other patient requirements and characteristics (i.e., age, race, need for drugs with specific benefits) and in collaboration with specialist in pediatric hypertension.
Weight management and treatment goals based on BMI percentile and health status  

BMI: <85th percentile (normal weight for height)

Guiding principles

Goal: Maintain BMI percentile to prevent overweight

Establish individual treatment goals and approaches based on the child's age, degree of overweight, and presence of comorbidities.

BMI: 85th to 95th percentile for age and gender (at risk for overweight)

Involve the family or major caregivers in treatment.

Goal: Maintain BMI with aging to reduce BMI to <85th percentile; if BMI >25 (kg/m2, weight maintenance

Provide assessment and monitoring frequently.

BMI: >95th percentile (overweight)

Consider behavioral, psychological, and social correlates of weight gain in the treatment plan.

Goal: Weight maintenance (younger children) or gradual weight loss (adolescents) to reduce BMI percentile

Provide recommendations for dietary changes, increasing daily physical activity and decreasing sedentary activities. Recommendations should be tailored to the characteristics, needs, and resources of the child and family, able to be implemented within the family environment, and designed to foster optimal child/family health, growth, and development.

BMI: >30 kg/m2 (adult obesity cut point)

 

Goal: Gradual weight loss (1-2 kg per month [kg/mo]) to achieve healthier BMI

 

BMI: >95th percentile and comorbidity present (overweight with comorbidity)

 

Goal: Gradual weight loss (1-2 kg/mo) to achieve healthier BMI; assess need for additional treatment of associated conditions

Ask about the behavior at every healthcare visit.

Involve the parents/family as partners in the behavioral change process.

Provide information in multiple developmentally and culturally appropriate venues.

Specific Strategies

Assess, monitor, and document patterns of behavior change at every healthcare visit.

Provide developmentally appropriate behavior-specific information tailored to the child's and family's cultural background, needs, and resources.

Identify realistic goals for behaviors with the child and family.

Include activities to assist families to monitor behaviors targeted for change.

Mobilize family and social support.

Provide self-efficacy enhancement and an atmosphere of clinical empathy.
