Recommendations made by the USPSTF are independent of the U.S. government. They should not be construed as an official position of the Agency for Healthcare Research and Quality or the U.S. Department of Health and Human Services.
Familial hypercholesterolemia (FH) and multifactorial dyslipidemia are two conditions that cause abnormally high lipid levels in children, which can lead to premature cardiovascular events (e.g., heart attack and stroke) and death in adulthood. FH is rare, with prevalence in U.S. children and adolescents ranging from 0.2% to 0.4% (1 out of every 250 to 500 children and adolescents). Multifactorial dyslipidemia is much more common than FH, with prevalence in children and adolescents ranging from 7.1% to 9.4%.1
The U.S. Preventive Services Task Force (USPSTF) concludes that the current evidence is insufficient, and the balance of benefits and harms for screening for lipid disorders in asymptomatic children and adolescents age 20 years or younger cannot be determined.
See the Table for more information on the USPSTF recommendation rationale and assessment. For more details on the methods the USPSTF uses to determine the net benefit, see the USPSTF Procedure Manual.2
Patient Population Under Consideration
This recommendation applies to asymptomatic children and adolescents age 20 years or younger without a known diagnosis of a lipid disorder.
FH is a genetic disorder of cholesterol metabolism characterized by very high levels of low-density lipoprotein cholesterol (LDL-C) early in life. This cumulative exposure to abnormal lipid levels over time can lead to early atherosclerotic changes and premature cardiovascular morbidity and mortality. Diagnosis of FH is variably defined but generally includes substantially elevated lipid levels, a monogenic mutation, or both. There are several variants that can individually lead to the FH phenotype, so genetic testing includes examination for each of these variants.1
Multifactorial dyslipidemia is a condition of elevated lipid levels primarily associated with environmental factors such as excessive intake of saturated fat, sedentary lifestyle, and obesity; small additive polygenic variants may also contribute to multifactorial dyslipidemia. Abnormal lipid values associated with multifactorial dyslipidemia are generally lower than those associated with FH.1
A serum lipid panel has been studied to screen for both FH and multifactorial dyslipidemia. Lipid panels measure different components of cholesterol metabolism including total cholesterol (TC), LDL-C, non–high-density lipoprotein cholesterol (non–HDL-C), triglycerides, and high-density lipoprotein cholesterol (HDL-C).1
Treatment interventions to lower lipid levels generally include lifestyle modification (e.g., changes in diet and physical activity), pharmacotherapy (e.g., statins, bile acid sequestering agents, or cholesterol absorption inhibitors), and dietary supplements (e.g., plant sterols or fish oil). Statins are approved by the U.S. Food and Drug Administration for use in children age 8 years or older and are the first-line pharmacotherapy treatment for children with elevated LDL-C levels. Treatment algorithms for FH and multifactorial dyslipidemia differ because of the substantially higher lipid levels associated with FH.1
Suggestions for Practice Regarding the I Statement
Potential Preventable Burden
FH is generally asymptomatic in childhood and adolescence and is rarely associated with cardiovascular events in the first two decades of life. However, FH can cause early cardiovascular morbidity and mortality in adulthood from cumulative exposure to high LDL-C levels and atherosclerotic changes starting as early as age 8 years.1
Robust evidence from studies conducted primarily before statins were commonly used show that a diagnosis of FH substantially increases risk for cardiovascular events in adulthood. A meta-analysis of 68,565 adults from six U.S. cohorts found that the FH phenotype, defined by an LDL-C level of 190 mg/dL or greater, was associated with an adjusted hazard ratio of 4.1 (95% confidence interval [CI], 1.2 to 13.4) for cardiovascular disease events over 30 years of followup, compared with a reference group defined by an LDL-C level of 130 mg/dL or greater. Investigators also found that the FH phenotype accelerated coronary heart disease risk by 10 to 20 years in men and 20 to 30 years in women.3 Observational studies in adults with FH recruited from lipid clinics suggest that the prognosis of FH has improved substantially with the advent of statin treatment.4,5
Prognostic data for FH as determined by genotype is more limited. Data suggest that carriers of the FH genetic variant are at increased risk for coronary artery disease at any level of LDL-C. For example, the odds ratio for coronary artery disease was 5.2 (95% CI, 4.4 to 6.2) for an individual with an LDL-C level of 190 to 220 mg/dL or greater but without a genetic variant (compared with an individual with an LDL-C level less than 130 mg/dL and no genetic variant). However, the odds ratio for coronary heart disease was 17.0 (95% CI, 5.3 to 77.9) among individuals with this level of LDL-C in the presence of an FH genetic variant.6
Multifactorial dyslipidemia in adulthood is widely established as a risk factor for cardiovascular disease based on evidence showing strong associations between cholesterol levels in adulthood and ischemic heart disease mortality.7 Linking elevated lipid levels in children to adult cardiovascular outcomes requires long followup. A 2022 publication from the International Childhood Cardiovascular Cohorts (i3C) Consortium suggests that elevated lipid levels in childhood (ages 3 to 19 years) are associated with fatal cardiovascular events in adulthood with 35 years of followup; however, the evidence is complicated by the role of adult lipid levels and lack of control for other risk factors.8
Available pharmacotherapy trials and observational followup studies in children and adolescents showed no significant differences in harms between control and intervention groups. Abnormal liver and musculoskeletal laboratory values were reported with statin use; however, most trials were short term and small with few events, leading to imprecise estimates. Additionally, the clinical importance of transient elevations in these laboratory values is unknown.1
Lipid screening in U.S. pediatric populations varies. Recent studies investigating screening practices in large U.S. healthcare organizations found universal screening rates of 2% to 9% in children ages 9 to 11 years. Higher weight status, non-white race or ethnicity, and the presence of comorbid conditions were associated with higher screening rates in these studies.1
Screening based on risk factors can be unreliable, leading to underdiagnosis and undertreatment. The genetic disorder that causes FH is not related to obesity and studies show that patient reports of family history of lipid disorders or premature cardiovascular events are inaccurate. Higher body mass index is a risk factor for multifactorial dyslipidemia; however, screening guided by weight status alone could miss a significant number of children with multifactorial dyslipidemia who do not have overweight or obesity. Another approach sometimes used is universal screening in certain age groups.1,9,10
There are no universally accepted criteria for the diagnosis of FH. A combination of elevated lipid levels, physical findings, family history, or genetic tests are used to establish the diagnosis. Abnormal lipid value cutpoints for defining multifactorial dyslipidemia are based on population norms and correspond to approximately the 95th percentile of population-based cohorts. These thresholds, however, have not been validated as predictors for cardiovascular disease events and are not age- and sex-specific.1
Additional Tools and Resources
The National Heart, Lung, and Blood Institute’s Expert Panel on Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents developed comprehensive evidence-based guidelines addressing the known risk factors for cardiovascular disease to assist all primary care professionals in both the promotion of cardiovascular health and the identification and management of specific risk factors from infancy into young adult life (https://www.nhlbi.nih.gov/node/80308).9
The U.S. Department of Health and Human Services published the “Physical Activity Guidelines for Americans,” which provide evidence-based recommendations for how physical activity can help promote health and reduce the risk of chronic disease for Americans age 3 years or older (https://health.gov/our-work/nutrition-physical-activity/physical-activity-guidelines).11
The U.S. Departments of Agriculture and Health and Human Services published the “Dietary Guidelines for Americans,” which provide advice on what to eat and drink at every stage of life to build a healthy diet that can help prevent chronic diseases (https://www.dietaryguidelines.gov/).12
The Community Preventive Services Task Force recommends interventions promoting physical activity and healthy eating across the lifespan, including specific recommendations for youth (https://www.thecommunityguide.org/).13
Other Related USPSTF Recommendations
The USPSTF recommends that clinicians screen for obesity in children age 6 years or older and offer them or refer them to a comprehensive, intensive behavioral intervention to promote improvements in weight status (B recommendation).14 The USPSTF found insufficient evidence on screening for high blood pressure in children and adolescents to prevent subsequent cardiovascular disease in childhood or adulthood (I statement).15
In 2016, the USPSTF found insufficient evidence to assess the balance of benefits and harms of screening for lipid disorders in children and adolescents age 20 years or younger (I statement).16 This recommendation concurs with the previous I statement.
Scope of Review
The USPSTF commissioned a systematic review to evaluate the benefits and harms of screening for lipid disorders in asymptomatic children and adolescents.1 In 2016, separate reports were issued for FH and multifactorial dyslipidemia. This systematic evidence review presents updated evidence in a single report that clearly delineates the evidence specific to each condition. The review on FH focuses on heterozygous FH. Homozygous FH and secondary causes of dyslipidemia (such as diabetes, nephrotic syndrome, or hypothyroidism) are outside the scope of the review.
Accuracy of Screening Tests and Risk Assessment
No studies performed a confirmatory lipid or genetic test; thus, evidence is limited to screen-positivity (prevalence) rather than diagnostic yield of lipid screening for identifying FH and multifactorial dyslipidemia. Prevalence of any lipid abnormality in 6- to 19-year-olds was 19.2% based on 2013 to 2016 data from the National Health and Nutrition Examination Survey (n=4,381).1
The USPSTF reviewed three fair-quality U.S. studies (n=395,465) reporting prevalence of FH ranging from 0.2% to 0.4% (1/250 to 1/500) using diagnostic criteria exclusively based on lipid levels (LDL-C ≥190 mg/dL or TC ≥270 mg/dL).1 One study screening for cardiovascular risks among fifth graders (n=20,266) found that among 14,468 students with a positive family history of premature cardiovascular disease, 1.2% had a fasting LDL-C level of 160 mg/dL or greater; 1.7% of 5,798 students without a family history of premature cardiovascular disease had a fasting LDL-C level of 160 mg/dL or greater.17 These results show that targeted screening in children with a family history of hypercholesterolemia or premature cardiovascular disease would miss many cases of children with an elevated LDL-C level of 160 mg/dL or greater.
The USPSTF reviewed five fair-quality studies (n=142,257) reporting prevalence of multifactorial dyslipidemia. Prevalence ranged from 7.1% to 9.4% for elevated TC level (≥200 mg/dL), 6.4% to 7.4% for elevated LDL-C level (≥130 mg/dL), 12.1% to 22.2% for low HDL-C level (<40 mg/dL), 8.0% to 17.3% for elevated triglycerides level (using various thresholds), and 6.4% to 13.0% for elevated non-HDL-C level (≥145 mg/dL). Older age and higher body mass index were associated with higher prevalence of multifactorial dyslipidemia.1
Benefits of Early Detection and Treatment
No studies directly assessed the effectiveness of screening for FH or multifactorial dyslipidemia in children and adolescents to delay or reduce poor health outcomes (e.g., cardiovascular disease events or mortality) or improve intermediate outcomes (e.g., serum lipid levels and atherosclerotic markers).1
The USPSTF reviewed 22 fair- to good-quality trials (n=2,257) examining the effectiveness of lipid-lowering treatments in individuals with FH, including pharmacotherapy, behavioral counseling, and dietary supplements. Trials were generally small and short term, and none reported effects on cardiovascular events or mortality. The evidence was strongest for statins causing the highest reductions in TC and LDL-C levels. Pharmacological effect on triglycerides and HDL-C levels was mixed. The review included 10 fair- to good-quality randomized, controlled trials (n=1,230) of statins with followup for up to 2 years. Pooled analyses demonstrated that statins were associated with an 81 to 82 mg/dL greater mean difference in TC and LDL-C levels compared with placebo (TC: 7 studies, n=706, mean difference in change, -82.1 mg/dL [95% CI, -101.1 to -63.2 mg/dL]; LDL-C: 8 studies, n=742, mean difference in change, -81.3 mg/dL [95% CI, -97.6 to -65.0 mg/dL]). Other studies reporting lipid-lowering effects from bile acid sequestrant, ezetimibe, PCSK9 inhibitor, and statin plus ezetimibe combination drugs showed statistically significant reductions but none as substantial as statins alone; mean difference in TC and LDL-C levels from nonstatin drugs ranged from mid to upper 60s. Despite large changes in LDL-C levels associated with statins, many children with FH do not achieve LDL-C goals due to high baseline values. No more than 60% of participants in the statin group achieved goal in any trial.1
Evidence from a very small fair-quality behavioral counseling trial in an FH population (n=21) showed that this intervention was not effective in lowering lipid levels or changing physical activity or diet behaviors. Supplements showed mixed results, with the best evidence supporting plant sterol spreads. Two fair-quality plant sterol supplement trials (n=82) in FH populations showed statistically significant reductions of 20.5 to 30.5 mg/dL in TC level and 22.4 to 30.1 mg/dL in LDL-C level at 4 to 8 weeks. Two trials of omega-3 fatty acids did not show a statistically significant difference in lipid level changes between the intervention and control groups.1
No trials of drug interventions in children and adolescents with multifactorial dyslipidemia met inclusion criteria. The USPSTF reviewed four fair- to good-quality trials (n=1,008) examining the effectiveness of various nonpharmacologic lipid-lowering treatments for multifactorial dyslipidemia. Two behavioral counseling trials (n=934) with dietary interventions varying in intensity, duration, and followup showed a 3- to 6-mg/dL statistically significant reduction in TC and LDL-C levels and improvements in dietary intake in the intervention group compared with the control group; however, these findings did not persist at longer followup. Two small fair-quality supplement intervention trials (n=74) examining flaxseed and fish oil in populations with multifactorial dyslipidemia showed that these supplements did not improve lipid outcomes at 4 to 8 weeks.1
The USPSTF reviewed seven fair- to good-quality short-term supplement trials (n=288) in populations of children and adolescents with FH or multifactorial dyslipidemia. Results for various supplement interventions were limited, inconsistent, or showed no difference between intervention and control groups.1
Harms of Screening and Treatment
No studies reported on the harms of screening for FH or multifactorial dyslipidemia in children and adolescents.1
Overall, harms reported in pharmacotherapy trials were similar in the intervention and control groups; however, most studies were relatively short term and small, with few events, leading to imprecise estimates. Further, the clinical importance of transient elevations in liver enzyme or creatine kinase levels is unknown.
In the statin trials discussed above, elevated liver enzyme levels of 3 times or more the upper limit of normal occurred in 0% to 4.5% of participants in intervention groups and 0% to 1.9% of participants in control groups. The largest trial (n=214) with 2-year followup reported no cases in the statin group and only 2 cases meeting the more than 3 times the upper limit of normal threshold in the control group. In the 10-year observational followup of this trial, elevated liver enzyme levels at this threshold were similarly rare.1 Elevations in musculoskeletal laboratory values were also rare. Abnormal creatine kinase levels 10 times or greater the upper limit of normal ranged from 0% to 4.5% of participants in the statin group and 0% to 1.7% of participants in the control group; one trial’s 10-year observational followup reported no instances of elevated creatine kinase levels. There were no significant differences in Tanner staging or hormonal adverse events between statin and placebo groups in these trials or with longer observational followup. A fair-quality observational study (n=9,393) evaluating the association of statins and new-onset diabetes showed no difference in new diabetes diagnoses over up to 9 years of followup in individuals taking statins compared with control groups.1
Studies reporting adverse events in nonstatin trials were small and short term and showed similar harms between the control and intervention groups. The diet and physical activity counseling intervention trial did not mention harms and the three supplement trials in FH reported that there were no adverse events.1
The two behavioral counseling trials discussed above reported no harms associated with this intervention. One small flaxseed study (n=32) noted a worsening in HDL-C and triglycerides levels; however, the small study size and fluctuation of lipid laboratory values over time and in different age groups makes the clinical significance of this finding unknown. A small fish oil study (n=42) noted that gastrointestinal symptoms, fishy taste, and frequent nose bleeds were more common in the intervention group than in the control group.1
In studies including individuals with FH and multifactorial dyslipidemia, gastrointestinal side effects were observed with fiber supplements. However, these studies were limited and had short trial durations of 5 to 16 weeks.1
How Does Evidence Fit With Biological Understanding?
The association between elevated adult lipid levels and adult cardiovascular events is well established. Evidence linking abnormal lipid levels in childhood to adult cardiovascular disease requires studies with decades-long followup. Three robust analyses suggest that cumulative exposure to elevated lipid levels in childhood and young adulthood is associated with adult cardiovascular disease; however, the evidence has limitations. The i3C Consortium published a pooled analysis of seven prospective cohort studies (n=38,589) that followed participants who had cardiovascular risk factors measured in childhood over a mean of 35 years and evaluated subsequent cardiovascular events in adulthood. Hazard ratios for a fatal cardiovascular event in adulthood were 1.30 (95% CI, 1.14 to 1.47) per unit increase in the z-score for TC level (which describes standard deviations from the mean) and 1.50 (95% CI, 1.33 to 1.70) per unit increase in the z-score for triglycerides level. This increased risk, however, dissipates and becomes nonstatistically significant when a combined risk factor score for adults is considered, suggesting the effect occurs largely because childhood risk factors track to adult risk factors. Additionally, the analysis used combined risk factors so individual cardiovascular risk factors, like lipid levels exclusively, were not examined independently.8 A pooled analysis of 36,030 participants from six U.S.-based cohort studies examined the independent association between exposure to high lipid levels in young adulthood (ages 18 to 39 years) and later cardiovascular events with a median followup period of 17 years. Results showed that exposure to LDL-C levels of 100 mg/dL or greater in young adulthood was associated with an adjusted hazard ratio of 1.64 (95% CI, 1.27 to 2.11) for coronary heart disease compared with LDL-C levels of less than 100 mg/dL in young adulthood.18 Another study selected genes associated with lower LDL-C levels and through a meta-analysis quantified the association between long-term lower LDL-C levels and the risk of coronary heart disease. Results suggested that lower LDL-C levels throughout the lifespan were associated with substantially lower coronary heart disease in adulthood compared with initiating treatment for lipid lowering later in life.19 Limitations for applicability of these data include risk factors that were combined and not independently evaluated, generalizability to younger ages in studies where participants were young adults, and measurement of health outcome in the third or fourth decade of life, which may be too early to detect a cardiovascular event.
A new 20-year followup study (n=214) from a randomized, controlled trial of children and their parents identified with FH demonstrated that early initiation of statins in adolescence was associated with improved cumulative cardiovascular disease–free survival at age 39 years compared with their parents’ delayed treatment in adulthood. Children with confirmed FH who started statins in youth (mean statin initiation age, 14.0 ± 3.1 years) had higher rates of cardiovascular disease–free survival compared with their parents, for whom statins were not available until adulthood (99% vs. 74% cardiovascular disease–free survival; hazard ratio, 11.8 [95% CI, 3.0 to 107.0], adjusted for sex and smoking status).20 Although promising data, several study characteristics may make results hard to translate to a general screen-detected pediatric population, including small sample size; generalizability to a primary care pediatric population, as all participants were recruited from a lipid clinic and ultimately confirmed to have an FH genetic mutation; and applicability to the U.S. population where genetic testing for FH may not be widely available or easily accessible.
Studies are needed that provide the following information.
- Long-term data on the effectiveness of screening for and treatment of lipid disorders in children and adolescents to prevent premature cardiovascular events or death in adulthood.
- Measurement of diagnostic yield of lipid screening tests through confirmatory lipid and genetic testing to identify children and adolescents with FH and multifactorial dyslipidemia.
- Comparative effectiveness data assessing the optimal age at which to start lipid-lowering interventions for maximal benefit in children and adolescents diagnosed with FH or multifactorial dyslipidemia, including benefits and harms of starting pharmacologic treatment as a child (e.g., ages 8 to 10 years) vs. as a young adult (early 20s).
- Long-term data on the harms of screening and treatment.
The National Heart, Lung, and Blood Institute’s Expert Panel on Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents, the American Academy of Pediatrics’ Bright Futures program, and the multisociety Guideline on the Management of Blood Cholesterol recommend selectively screening children with a family history of cardiovascular disease or dyslipidemia or other risk factors as early as age 2 years. They also recommend universally screening children ages 9 to 11 years and again at ages 17 to 21 years.9,10,21 The American Academy of Family Physicians references the USPSTF’s 2016 conclusion of insufficient evidence to recommend for or against routine screening for lipid disorders in children and adolescents.22 International guidelines for lipid screening in children and adolescents vary.
