Effect of relative weight group change on nuclear magnetic resonance spectroscopy derived lipoprotein particle size and concentrations among adolescents. J Pediatr 2014; 164:1091-1098.e3. [PMID: 24508445 PMCID: PMC3992168 DOI: 10.1016/j.jpeds.2013.12.029] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/19/2013] [Revised: 10/24/2013] [Accepted: 12/13/2013] [Indexed: 12/14/2022]
Abstract
OBJECTIVE To examine whether longitudinal changes in relative weight category (as indicated by change in body mass index [BMI] classification group) were associated with changes in nuclear magnetic resonance (NMR)-derived lipoprotein particles among US youth. STUDY DESIGN Secondary analysis of data from a clustered randomized controlled trial. BMI and fasting blood samples were obtained from 2069 participants at the start of the 6th grade and end of the 8th grade. BMI was categorized as normal weight, overweight, or obese at both time points. Lipoprotein particle profiles were measured with NMR spectroscopy at both time points. Regression models were used to examine changes in relative weight group and change in lipoprotein variables. RESULTS A total of 38% of participants changed relative weight category (BMI group) during the 2.5-year study period. Low-density lipoprotein (LDL) cholesterol and non-high-density lipoprotein (HDL) cholesterol decreased almost universally, but more with improved BMI category. There were adverse effects on LDL size and total LDL particles, HDL size, and cholesterol for participants who remained obese or whose relative weight group worsened. Changes in relative category had no impact on HDL particles. CONCLUSION Improvement in relative weight group from 6th to 8th grade was associated with favorable changes in non-HDL cholesterol, very low-density lipoprotein size, LDL size, HDL size, and LDL particles but had no effect on HDL particles. Findings indicate that an improvement in relative weight group between 6th and 8th grade had an effect on NMR-derived particles sizes and concentrations among a large group of adolescents, which overrepresented low-income minorities.

Abstract
PURPOSE OF REVIEW To detail recent developments linking modifiable youth risk factors with preclinical markers of cardiovascular disease such as carotid artery intima-media thickness, pulse-wave velocity (PVW) and large artery stiffness, brachial artery flow-mediated dilatation, left ventricular geometry, and coronary artery calcification in adulthood. RECENT FINDINGS Population-based data from prospective cohort studies beginning in youth with follow-up into adulthood have shown that the modifiable youth risk factors of elevated blood lipids, blood pressure, and adiposity, smoking (active and passive), metabolic disorders, physical inactivity, low cardiorespiratory fitness, and diet associate with preclinical markers of cardiovascular disease in adulthood. The data suggest that, in some instances, those who amend their trajectory by not maintaining these risk factors into adulthood experience reductions in preclinical markers to levels associated with never having had the risk factor. SUMMARY Though avoidance of risk factors in youth is ideal, there is still a window for intervention where long-lasting cardiovascular effects might be avoided. Health-enhancing changes in the rates of active and passive smoking, adiposity, increased physical activity, accentuated fitness, modified diet, and socioeconomic position in the transition from youth to adulthood might be important in modifying an individual's trajectory from high risk in youth to low risk in adulthood.

Abstract
AIM Recent evidence suggests that the exposure of children to their parents' smoking adversely effects endothelial function in adulthood. We investigated whether the association was also present with carotid intima-media thickness (IMT) up to 25 years later. METHODS AND RESULTS The study comprised participants from the Cardiovascular Risk in Young Finns Study (YFS, n = 2401) and the Childhood Determinants of Adult Health (CDAH, n = 1375) study. Exposure to parental smoking (none, one, or both) was assessed at baseline by questionnaire. B-mode ultrasound of the carotid artery determined IMT in adulthood. Linear regression on a pooled dataset accounting for the hierarchical data and potential confounders including age, sex, parental education, participant smoking, education, and adult cardiovascular risk factors was conducted. Carotid IMT in adulthood was greater in those exposed to both parents smoking than in those whose parents did not smoke [adjusted marginal means: 0.647 mm ± 0.022 (mean ± SE) vs. 0.632 mm ± 0.021, P = 0.004]. Having both parents smoke was associated with vascular age 3.3 years greater at follow-up than having neither parent smoke. The effect was independent of participant smoking at baseline and follow-up and other confounders and was uniform across categories of age, sex, adult smoking status, and cohort. CONCLUSIONS These results show the pervasive effect of exposure to parental smoking on children's vascular health up to 25 years later. There must be continued efforts to reduce smoking among adults to protect young people and to reduce the burden of cardiovascular disease across the population.

Abstract
BACKGROUND The American Heart Association recently defined ideal cardiovascular health by simultaneous presence of seven health behaviors and factors. The concept is associated with cardiovascular disease incidence, and cardiovascular disease and all-cause mortality. To effectively promote ideal cardiovascular health already early in life, childhood factors predicting future ideal cardiovascular health should be investigated. Our aim was thus to comprehensively explore childhood determinants of adult ideal cardiovascular health in population based cohorts from three continents. METHODS The sample comprised a total of 4409 participants aged 3-19 years at baseline from the Cardiovascular Risk in Young Finns Study (YFS; N = 1883) from Finland, Childhood Determinants of Adult Health Study (CDAH; N = 1803) from Australia and Princeton Follow-up Study (PFS; N = 723) from the United States. Participants were re-examined 19-31 years later when aged 30-48 years. RESULTS In multivariable analyses, independent childhood predictors of adult ideal cardiovascular health were family socioeconomic status (P < 0.01; direct association) and BMI (P < 0.001; inverse association) in all cohorts. In addition, blood pressure (P = 0.007), LDL-cholesterol (P < 0.001) and parental smoking (P = 0.006) in the YFS, and own smoking (P = 0.001) in CDAH were inversely associated with future ideal cardiovascular health. CONCLUSIONS Among several lifestyle and clinical indicators studied, higher family socioeconomic status and non-smoking (parental/own) in childhood independently predict ideal cardiovascular health in adulthood. As atherosclerotic cardiovascular diseases are rooted in childhood, our findings suggest that special attention could be paid to children who are from low socioeconomic status families, and who smoke or whose parents smoke, to prevent cardiovascular disease morbidity and mortality.

Abstract
The report of the National Heart, Lung and Blood Institute Expert Panel on Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents collects into one document atherosclerotic disease prevention in pediatric age groups. The guidelines summarize the evidence base and make recommendations that encourage universal adoption of healthier lifestyles, identification of children with cardiovascular disease risk factors, and treatment of those risk factors using targeted lifestyle modification and rarely pharmacotherapy. These recommendations highlight childhood as a frontier for cardiovascular disease prevention. The guideline recommendations are controversial and not universally embraced, but at the very least, they suggest directions for important research. This article explores key facets of the guidelines, controversies and future directions in preventive cardiology for children.

Abstract
BACKGROUND Goals for cardiovascular (CV) disease prevention were set by the American Heart Association in 2010 for the concept of CV health. Ideal CV health is defined by 7 CV health metrics: blood pressure, glucose, cholesterol, body mass index, and physical activity on recommended levels; nonsmoking; and a healthy diet. We studied the prevalence of ideal CV health and its associations with ultrasonographically measured carotid intima-media thickness (cIMT) cross-sectionally in 5 international populations. METHODS AND RESULTS Prevalence of ideal CV health was assessed among 5785 young adults (age, 36.6 ± 3.2 years) comprising 335 participants from the Minneapolis Childhood Cohort Studies (Minnesota), 723 from the Princeton Follow-up Study, 981 from the Bogalusa Heart Study (BHS), 1898 from the Cardiovascular Risk in Young Finns Study (YFS), and 1848 from the Childhood Determinants of Adult Health Study (CDAH). Only 1% of the participants had all 7 ideal CV health metrics. The number of ideal CV health metrics associated inversely with cIMT in the 4 cohorts in which cIMT was available: for each additional ideal CV health metric, cIMT was 12.7 μm thinner in Minnesota (P=0.0002), 9.1 μm thinner in BHS (P=0.05), 10.4 μm thinner in YFS (P<0.0001), and 3.4 μm thinner in CDAH (P=0.03). CONCLUSIONS The number of ideal CV health metrics was inversely associated with cIMT in the cohorts in which cIMT was available, indicating that ideal CV health metrics are associated with vascular health at the population level. Ideal CV health was rare in this large international sample of young adults, emphasizing the need for effective strategies for health promotion.

Abstract
BACKGROUND Elevated blood pressure (BP) levels in childhood have been associated with subsequent atherosclerosis. However, it is uncertain whether this risk is attenuated in individuals who acquire normal BP by adulthood. The present study examined the effect of child and adult BP levels on carotid artery intima-media thickness (IMT) in adulthood. METHODS AND RESULTS The cohort consisted of 4210 participants from 4 prospective studies (mean follow-up, 23 years). Childhood elevated BP was defined according to the tables from the National High Blood Pressure Education Program. In adulthood, BP was classified as elevated for individuals with systolic BP ≥120 mm Hg, diastolic BP ≥80 mm Hg or with self-reported use of antihypertensive medications. Carotid artery IMT was measured in the left common carotid artery. High IMT was defined as an IMT ≥90th percentile according to age-, sex-, race-, and cohort-specific levels. Individuals with persistently elevated BP and individuals with normal childhood BP, but elevated adult BP had increased risk of high carotid artery IMT (relative risk [95% confidence interval]) 1.82[1.47-2.38] and 1.57[1.22-2.02], respectively) in comparison with individuals with normal child and adult BP. In contrast, individuals with elevated BP as children but not as adults did not have significantly increased risk (1.24[0.92-1.67]). In addition, these individuals had a lower risk of increased carotid artery IMT (0.66[0.50-0.88]) in compared with those with persistently elevated BP. The results were consistent when controlling for age, sex, and adiposity and when different BP definitions were applied. CONCLUSIONS Individuals with persistently elevated BP from childhood to adulthood had increased risk of carotid atherosclerosis. This risk was reduced if elevated BP during childhood resolved by adulthood.

Abstract
This is a consortium of large children's cohorts that contain measurements of major cardiovascular disease (CVD) risk factors in childhood and had the ability to follow those cohorts into adulthood. The purpose of this consortium is to enable the pooling of data to increase power, most importantly for the follow-up of CVD events in adulthood. Within the consortium, we hope to be able to obtain data on the independent effects of childhood and early adult levels of CVD risk factors on subsequent CVD occurrence.

Abstract
We evaluate the relationship between different lipoproteins and atherogenic indices with pre-hypertension in 297 obese and 942 non-obese children with Tanner stage 1 enrolled in a multicentre, community-based cross-sectional study. Height, weight, fasting glucose and insulin levels, total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c), non-HDL-c, LDL/HDL-c, triglycerides/cholesterol and total cholesterol/HDL-c ratios were measured. Mean age was 8.4 ± 1.2 years; pre-hypertension was identified in 104 (8.4%) participants, 46 (15.5%) obese and 58 (6.1%) non-obese children. The pre-hypertensive non-obese children show a high proportion of family history of hypertension (41.6 and 24.7%, p = 0.002) and elevation of insulin at a relatively low body mass index. The triglycerides:HDL-c ratio, but not other lipoproteins or atherogenic indices, was associated with pre-hypertension in obese (1.15, 95% confidence intervals 1.06-1.26) and non-obese children (1.38 95% confidence intervals 1.22-1.57). The triglycerides:HDL-c ratio is related to pre-hypertension in children; the family history of hypertension seems to be a risk factor in developing pre-hypertension.

Abstract
Purpose. Ready-to-eat cereal (RTEC) consumption has been associated with better nutrient intakes and anthropometric end points compared with breakfast skipping and other breakfasts. Our objective was to evaluate RTEC breakfast type (presweetened and nonpresweetened) on physiological end points. Methods. National Health and Nutrition Examination Survey 2003-2006 data were analyzed using SUDAAN. Participants (n = 6729; 2-17 years) were separated into groups based on breakfast habits as follows: presweetened RTEC (PS-RTEC); nonpresweetened RTEC (NPS-RTEC); breakfast skippers (SKs); other breakfasts (OBs). Presweetened was defined as ≥9 g of added sugars per serving. Results. No differences were found for weight, BMI, waist circumference, blood pressure, or lipids in children consuming PS-RTECs or NPS-RTECs. In children 12 to 17 years old, BMI and percentage of children overweight or obese were lower for consumers of PS-RTECs at breakfast compared with SK or OB groups. Skinfolds were significantly lower in PS-RTEC versus SK or OB groups. SK and OB children (12-17 years old) were nearly twice as likely to be overweight or obese as compared with children consuming PS-RTECs (odds ratio of 1.87 and 2.12, respectively). Conclusion. Consumption of breakfast cereal with higher or lower added sugar was not associated with unhealthy physiological end points in children. The study confirms the association between RTEC consumption and healthier body weights compared with children and adolescents skipping or consuming a non-RTEC breakfast.

Abstract
This review provides an up-to-date summary of findings from two ongoing population-based, prospective studies conducted in Finland: The Cardiovascular Risk in Young Finns Study, and the Special Turku Coronary Risk Factor Intervention Project (STRIP), which have contributed significantly to the scientific literature concerning the childhood origin of cardiovascular disease, and whether prevention efforts in adults can be expanded to young people. From the Young Finns Study, we summarize evidence demonstrating childhood risk factors to be associated with both risk factors and preclinical markers of atherosclerosis in adulthood, and from STRIP, we summarize evidence showing that supervised dietary counseling of a low saturated fat diet effectively decreases exposure to cardiovascular risk factors without affecting growth and development of healthy children and adolescents. The evidence available from these studies supports that the ability to prevent or delay the risk of premature atherosclerosis and its clinical sequelae later in life lies in maintaining a low lifetime risk by preventing the development of risk factors in early life.

[PMID: 22937812 PMCID: PMC3477115 DOI: 10.1186/1476-511x-11-107] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2012] [Accepted: 08/19/2012] [Indexed: 11/01/2022] Open
Abstract
BACKGROUND To compare the predictive ability of adolescent lipoprotein classification using the National Examination Survey (NHANES) cut points and those of the National Cholesterol Education Program (NCEP) for predicting abnormal levels in adulthood. METHOD From 1032 adolescents, aged 14-19 years, participants of the Tehran Lipid and Glucose Study, all lipid measures were determined at baseline and again after 6 years. Multivariable Odds Ratios (ORs) were calculated for borderline and high categories of lipids to predict dyslipidemia in adulthood, considering the normal level as a reference. Area under the receiving characteristics curve (AUC) was used to assess the predictive ability of each adolescent lipid classification. RESULT Applying the NCEP classification, the prevalences of high total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglycerides and low high density lipoprotein cholesterol (HDL-C) in males were 12.1%, 12.9%, 26.1% and 34.2% respectively; in females the corresponding prevalences were 15.4%, 17.9%, 21.4% and 25.0%, respectively. Using NHANES cut points, the prevalence of high TC, LDL-C and triglycerides were lower, than those defined by NCEP; the ORs of high categories of lipids (defined by NHANES) were higher than ORs based on the NECP classification, except for HDL-C. For all lipid measures, both classifications had similar predictive abilities, except for TC/HDL-C, which had higher predictive power applying the NHANES classification rather than the NCEP one (AUC 71% vs. 68%, respectively). CONCLUSION No differences were found between NCEP and NHANES classifications for prediction of adult dyslipidemia, except for TC/HDL-C. Because of their simple application, NCEP cut points can be used in clinical settings.

Abstract
Background Pediatric risk factors predict adult cardiovascular disease (CVD) and type 2 diabetes (T2DM), but whether they predict events independently of adult risk factors is not fully known. Objective Assess whether risk factors for CVD and T2DM retained from childhood to adulthood predict CVD and T2DM in young adulthood. Study design 770 schoolchildren, ages 5–20 (mean age 12), 26-yr prospective follow-up. We categorized childhood and adult risk factors and 26-year changes (triglycerides [TG], LDL cholesterol, BMI, blood pressure [BP] and glucose ≥, and HDL cholesterol < pediatric and young adult cutoffs). These risk factors and race, cigarette smoking, and family history of CVD and T2DM were assessed as predictors of CVD and T2DM at mean age 38. Results Children who had high TG and retained high TG as adults had increased CVD events as adults (p = .0005). Children who had normal BMI and retained normal BMI as adults had reduced CVD events as adults (p = .02). Children who had high BP or high TG and retained these as adults had increased T2DM as adults (p = .0006, p = .003). Conclusions Risk factors for CVD and T2DM retained from childhood to adulthood predict CVD and T2DM in young adulthood and support universal childhood screening.

Metabolism 2012; 61:531-41. [PMID: 22001337 PMCID: PMC3324938 DOI: 10.1016/j.metabol.2011.08.010] [Citation(s) in RCA: 74] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2011] [Revised: 08/26/2011] [Accepted: 08/30/2011] [Indexed: 01/03/2023]
Abstract
The objective was to assess whether pediatric risk factors predict cardiovascular disease (CVD), impaired fasting glucose (IFG) + type 2 diabetes mellitus (T2DM), and high blood pressure (HBP) in young adulthood. We performed a prospective follow-up of 909 public-parochial suburban schoolchildren first studied at ages 6 to 18 years and 26 years later at a mean age of 38 years. Pediatric triglycerides (TGs), blood pressure, low-density lipoprotein cholesterol, body mass index, and glucose above and high-density lipoprotein cholesterol below established pediatric cutoffs, along with race, cigarette smoking, family history of CVD, T2DM, and HBP, were assessed as determinants of young adult CVD, a composite variable including IFG + T2DM and HBP. By stepwise logistic regression, adult CVD (19 yes, 862 no) was associated with pediatric high TG (odds ratio [OR], 5.85; 95% confidence interval [CI], 2.3-14.7). High TG in pediatric probands with young adult CVD was familial and was associated with early CVD in their high-TG parents. Adult IFG + T2DM (114 yes, 535 no) was associated with parental T2DM (OR, 2.2; 95% CI, 1.38-3.6), high childhood glucose (OR, 4.43; 95% CI, 2-9.7), and childhood cigarette smoking (OR, 1.64; 95% CI, 1.03-2.61). Adult HBP (133 yes, 475 no) was associated with pediatric high body mass index (OR, 2.7; 95% CI, 1.7-4.3) and HBP (OR, 2.5; 95% CI, 1.5-4.3). Pediatric risk factors are significantly, independently related to young adult CVD, IFG + T2DM, and HBP. Identification of pediatric risk factors for CVD, IFG + T2DM, and HBP facilitates initiation of primary prevention programs to reduce development of adult CVD, IFG + T2DM, and HBP.

Abstract
Objective—
Passive smoking has been associated with increased cardiovascular morbidity. The present study aimed to examine the long-term effects of childhood exposure to tobacco smoke on endothelium-dependent vasodilation in adults.
Methods and Results—
The analyses were based on 2171 participants in the population-based Cardiovascular Risk in Young Finns (N=2067) and Childhood Determinants of Adult Health (N=104) studies who had measures of conventional risk factors (lipids, blood pressure, adiposity, socioeconomic status) and self-reported parental smoking status when aged 3 to 18 years at baseline. They were re-examined 19 to 27 years later when aged 28 to 45 years. Brachial artery flow-mediated dilatation was measured at follow-up with ultrasound. In analyses adjusting for age, sex, and childhood risk factors, flow-mediated dilatation was reduced among participants who had parents that smoked in youth compared to those whose parents did not smoke (Young Finns: 9.2±0.1% (mean±SEM) versus 8.6±0.1%,
P
=0.001; Childhood Determinants of Adult Health: 7.4±0.6% versus 4.9±0.9%,
P
=0.04). These effects remained after adjustment for adult risk factors including own smoking status (Young Finns,
P
=0.003; Childhood Determinants of Adult Health,
P
=0.03).
Conclusion—
Parental smoking in youth is associated with reduced flow-mediated dilatation in young adulthood measured over 20 years later. These findings suggest that passive exposure to cigarette smoke among children might cause irreversible impairment in endothelium-dependent vasodilation.

Abstract
OBJECTIVE To evaluate children's cardiovascular disease (CVD) risk factors as predictors of parents' subsequent CVD, type 2 diabetes mellitus (T2DM), and high blood pressure (HBP). STUDY DESIGN We conducted a 26-year prospective follow-up of 852 5- to 19-year-old black and white schoolchildren (mean age, 12 years; Lipid Research Clinics, 1973-8), and parents (mean age, 40 years) from 519 families in Princeton Schools, Cincinnati, Ohio. Schoolchildren were reassessed in the Princeton Follow-up study 1999-2003 at mean age 39 years; CVD, T2DM, and HBP history of their 1038 parents were reassessed by mean age 66 years. We assessed relationships of childhood risk factors with parental CVD, T2DM, and HBP. Child-probands identified with triglyceride (TG) levels, blood pressure, low-density lipoprotein cholesterol levels, body mass index (BMI), and glucose level greater than and high-density lipoprotein cholesterol levels less than established cutoff points. RESULTS Pediatric HBP (P=.006) and low high-density lipoprotein cholesterol (P=.018) were predictive of parental CVD at age ≤50 years. Pediatric HBP (P=.02) and high TG (P=.03) were predictive of parental CVD at age ≤60 years. Pediatric high TG (P=.009) and high low-density lipoprotein cholesterol (P=.04) were predictive of parental CVD by age 66 years. Pediatric high BMI (P=.0006) were predictive of parental T2DM. Pediatric high BMI (P=.003) and black race (P=.004) were predictive of parental HBP. CONCLUSIONS Pediatric risk factors identify families with parents at increased risk for CVD, T2DM, and HBP, emphasizing the usefulness of the child as proband.

Abstract
BACKGROUND The American Heart Association (AHA) defined a new concept, cardiovascular health, and determined metrics needed to monitor it over time as part of its 2020 Impact Goal definition. Ideal cardiovascular health is defined by the presence of both ideal health behaviors and ideal health factors. The applicability of this concept to a cohort of children and its relationship with cardiometabolic outcomes in adulthood has not been reported. METHODS AND RESULTS The sample comprised 856 participants aged 12 to 18 years (mean age 15.0 years) from the Cardiovascular Risk in Young Finns Study cohort. Participants were followed up for 21 years since baseline (1986) and had data available concerning health factors and behaviors in childhood and cardiometabolic outcomes in adulthood (2007). The number of ideal cardiovascular health metrics present in childhood was associated with reduced risk of hypertension (odds ratio [95% confidence interval] 0.66 [0.52-0.85], P<0.001), metabolic syndrome (0.66 [0.52-0.77], P<0.001), high low-density lipoprotein cholesterol (0.66 [0.52-0.85], P=0.001), and high-risk carotid artery intima-media thickness (0.75 [0.60-0.94], P=0.01) in adulthood. All analyses were age and sex adjusted, and the results were not altered after additional adjustment with socioeconomic status. CONCLUSIONS The number of ideal cardiovascular health metrics present in childhood predicts subsequent cardiometabolic health in adulthood. Our findings suggest that pursuit of ideal cardiovascular health in childhood is important to prevent cardiometabolic outcomes in adulthood.

Abstract
Familial hypercholesterolaemia is a disorder of low-density lipoprotein (LDL) cholesterol metabolism, which is associated with the onset of vascular changes associated with coronary heart disease in childhood. This disorder has co-dominant transmission with a prevalence of one in 500 in the general population. Cascade screening is the most effective method of identifying children. Children in the at-risk group should have their cholesterol levels checked between the age of 2 and 10 years. Children with LDL cholesterol levels ≥ 3.4 mmol/L are likely to suffer from this disorder, although at this level there is a significant false positive rate. Molecular genetic testing is available for the LDL receptor gene, APOB gene and the PCSK9 gene. This is the most specific test for familial hypercholesterolaemia but has a false negative rate of 20-50%. Once diagnosed, treatment should be considered in children with an LDL cholesterol level ≥ 4.9 mmol/L. If the child has two other risk factors or a positive family history, this threshold should be lowered to ≥4.1 mmol/L. Guidelines recommend that treatment should be commenced by the age of 10 years, although some advise waiting until menarche in females. Statin therapy is currently recommended as first line treatment. Randomised placebo trials have shown that statin therapy reduces LDL cholesterol levels by 25% and is not associated with increased risk of adverse events. These are short-term studies, and longer follow-up will be required to definitively prove efficacy and safety.

Abstract
OBJECTIVE To evaluate whether the high triglyceride-to-HDL cholesterol (TG-to-HDL-C) ratio is associated with cardiometabolic risk (CMR) factors and preclinical signs of organ damage in an outpatient population of white children and adolescents. RESEARCH DESIGN AND METHODS The study population included 884 subjects (aged 6-16 years), of whom 206 (23%) were normal weight, 135 (15%) were overweight, and 543 (61%) were obese. Biochemical variables were analyzed in the whole sample, whereas homocysteine and left ventricular (LV) geometry and function were evaluated in 536 and 258 children, respectively. RESULTS The percentage of pubertal children (P < 0.001), as well as measurements of BMI, waist circumference, homeostasis model assessment of insulin resistance, white blood cell count, alanine aminotransferase (ALT), systolic blood pressure (P < 0.0001, for all), creatinine (P < 0.001), and diastolic blood pressure (P < 0.02), increased from the lowest to the highest tertile of the TG-to-HDL-C ratio. Age, sex, homocysteine, and glomerular filtration rate did not change. Moreover, interventricular septum thickness, relative wall thickness, and LV mass index (P = 0.01 to P < 0.0001) increased across tertiles of the TG-to-HDL-C ratio. Children with a TG-to-HDL-C ratio ≥2.0 showed a two- to threefold higher risk of elevated ALT levels and concentric LV hypertrophy than those with a TG-to-HDL-C ratio <2.0, independent of confounding factors. CONCLUSIONS The high TG-to-HDL-C ratio is associated with several CMR factors and preclinical signs of liver and cardiac abnormalities in the outpatient, white pediatric population. Thus, a TG-to-HDL-C ratio ≥2.0 may be useful in clinical practice to detect children with a worsened CMR profile who need monitoring to prevent cardiovascular disease in adulthood.

Abstract
An awareness of the presence of cardiovascular disease risk factors since childhood is essential to guide health promotion policies. The aim of this paper is to present, together with the main results, a methodological proposal to estimate both incidence and prevalence of these factors over time and their associated socio-demographic aspects in a population attending a primary health care unit, within Brazilian Unified National Health System. An open cohort design was adopted, starting in 2004 with a sample of 356 children aged between 5 and 9. In the second wave, in 2008, 126 children were enrolled and 205 were reevaluated. Socioeconomic variables, food intake, physical activity, anthropometric measures (weight, height and waist size), lipidogram and glycemia were collected. Results indicate a high prevalence of dyslipidemia, and an increase of excess weight and sedentary activity between both surveys. Some 55% of children were found to have lower values of HDL-cholesterol. The methodological proposal was considered adequate for the monitoring of cardiovascular disease predictors in poor urban populations.

Abstract
BACKGROUND Obesity in childhood is associated with increased cardiovascular risk. It is uncertain whether this risk is attenuated in persons who are overweight or obese as children but not obese as adults. METHODS We analyzed data from four prospective cohort studies that measured childhood and adult body-mass index (BMI, the weight in kilograms divided by the square of the height in meters). The mean length of follow-up was 23 years. To define high adiposity status, international age-specific and sex-specific BMI cutoff points for overweight and obesity were used for children, and a BMI cutoff point of 30 was used for adults. RESULTS Data were available for 6328 subjects. Subjects with consistently high adiposity status from childhood to adulthood, as compared with persons who had a normal BMI as children and were nonobese as adults, had an increased risk of type 2 diabetes (relative risk, 5.4; 95% confidence interval [CI], 3.4 to 8.5), hypertension (relative risk, 2.7; 95% CI, 2.2 to 3.3), elevated low-density lipoprotein cholesterol levels (relative risk, 1.8; 95% CI, 1.4 to 2.3), reduced high-density lipoprotein cholesterol levels (relative risk, 2.1; 95% CI, 1.8 to 2.5), elevated triglyceride levels (relative risk, 3.0; 95% CI, 2.4 to 3.8), and carotid-artery atherosclerosis (increased intima-media thickness of the carotid artery) (relative risk, 1.7; 95% CI, 1.4 to 2.2) (P ≤ 0.002 for all comparisons). Persons who were overweight or obese during childhood but were nonobese as adults had risks of the outcomes that were similar to those of persons who had a normal BMI consistently from childhood to adulthood (P>0.20 for all comparisons). CONCLUSIONS Overweight or obese children who were obese as adults had increased risks of type 2 diabetes, hypertension, dyslipidemia, and carotid-artery atherosclerosis. The risks of these outcomes among overweight or obese children who became nonobese by adulthood were similar to those among persons who were never obese.

Abstract
OBJECTIVE We analyzed the magnitude of the association between cardiovascular disease (CVD) risk factors and various measures of overweight among adolescents, to determine which indicator of overweight is most relevant for risk assessment. METHODS 5,546 boys and girls aged 11-17 years participating in the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) were studied. Overweight was assumed when different anthropometric variables exceeded age- and sex-specific 90th percentiles. Blood pressure was measured and blood samples were analyzed for serum total cholesterol, lipoproteins, high-sensitivity C-reactive protein, and glycosylated hemoglobin (HbA1c). RESULTS In both sexes, overweight was significantly associated with adverse levels of CVD risk factors, except HbA1c. These associations were most pronounced for overweight as defined by waist circumference (WC), waist-to-height ratio (WHtR), or BMI. Between 11% and 37% of the overweight children exceeded the defined cut-offs for individual CVD risk factors, with age- and puberty-adjusted significant odds ratios (95% confidence interval (CI)) in comparison to normal-weight age mates ranging from 1.7 (1.0-3.0) to 6.1 (4.5-8.2). CONCLUSIONS The findings of this population-based survey suggest that, among adolescents, WC, WHtR, and BMI are easily applicable measures of overweight that appear to be relevant for CVD risk assessment.

Abstract
OBJECTIVES To examine tracking and predictiveness of childhood lipid levels, blood pressure, and body mass index for risk profile in adulthood and the best age to measure the childhood risk factor levels. STUDY DESIGN Study subjects were participants of the longitudinal Cardiovascular Risk in Young Finns Study, started in 1980 (age 3, 6, 9, 12, 15, and 18 years). A total of 2204 subjects participated to the 27-year follow-up in 2007 (age, 30 to 45 years). RESULTS In both sex groups and in all age groups, childhood risk factors were significantly correlated with levels in adulthood. The correlation coefficients for cholesterol levels and body mass index were 0.43 to 0.56 (P < .0001), and for blood pressure and triglyceride levels, they were 0.21 to 0.32 (P < .0001). To recognize children with abnormal adult levels, the National Cholesterol Education Program and the National High Blood Pressure Education Program cutoff points for lipid and blood pressure values and international cutoff points for overweight and obesity were used. Age seemed to affect associations. The best sensitivity and specificity rates were observed in 12- to 18-year-old subjects. CONCLUSIONS Childhood blood pressure, serum lipid levels, and body mass index correlate strongly with values measured in middle age. These associations seemed to be stronger with increased age at measurements.

Abstract
BACKGROUND BMI is one factor that is used to determine a child's eligibility for lipid screening and treatment. BMI, which is an indirect measure of body fat, may inadequately represent the biological effect of body fat percentage on lipid concentrations. OBJECTIVE We examined the relation between directly measured body fat percentage and lipid concentrations in a representative sample of US youths. DESIGN Data from 7821 participants aged 8-19 y from the 1999-2004 NHANES were analyzed. Body fat percentage was measured by dual-energy X-ray absorptiometry. Total and HDL-cholesterol concentrations were measured in serum. Serum triglyceride and LDL-cholesterol concentrations were measured in a subsample of 2661 fasting NHANES participants aged 12-19 y. Prevalences of adverse total cholesterol (>200 mg/dL), LDL cholesterol (>130 mg/dL), triglycerides (>150 mg/dL), and HDL cholesterol (<35 mg/dL) were measured. RESULTS Approximately 10.0% [±0.7% (SE)] of participants had high total cholesterol, 7.0 ± 0.4% of participants had low HDL cholesterol, 9.7 ± 1.0% of participants had high triglycerides, and 7.6 ± 0.7% of participants had high LDL cholesterol. Prevalence of adverse total cholesterol, HDL cholesterol, triglycerides, and LDL cholesterol in US youths with high adiposity (greater than or equal to the age- and sex-specific 75th percentile of body fat percentage) was significantly greater (P < 0.01) than for participants without high adiposity. In multiple linear regressions adjusted for age, survey period, and race-ethnicity, the variance in lipid concentrations explained by body fat percentage was 2-20% (P < 0.001). CONCLUSION Adverse lipid concentrations and high adiposity are significantly associated in youths.

Abstract
The prevalence and severity of pediatric obesity have dramatically increased since the late 1980s, raising concerns about a subsequent increase in cardiovascular outcomes. Strong evidence, particularly from autopsy studies, supports the concept that precursors of adult cardiovascular disease (CVD) begin in childhood, and that pediatric obesity has an important influence on overall CVD risk. Lifestyle patterns also begin early and impact CVD risk. In addition, obesity and other CVD risk factors tend to persist over time. However, whether childhood obesity causes adult CVD directly, or does so by persisting as adult obesity, or both, is less clear. Regardless, sufficient data exist to warrant early implementation of both obesity prevention and treatment in youth and adults. In this Review, we examine the evidence supporting the impact of childhood obesity on adult obesity, surrogate markers of CVD, components of the metabolic syndrome, and the development of CVD. We also evaluate how obesity treatment strategies can improve risk factors and, ultimately, adverse clinical outcomes.

Abstract
ABSTRACTThis review was undertaken for the Faculty and Institute of Actuaries as part of their programme to encourage research collaborations between health researchers and actuaries in order to understand better the factors influencing mortality and longevity. The authors presented their findings in a number of linked sessions at the Edinburgh conference (Joining Forces on Mortality and Longevity) in October 2009 and contributed to this overview. The purpose is to review evidence for the impact on adult mortality of characteristics of the individual's lifetime socioeconomic or psychosocial environment or phenotype at the behavioural; multi-system (e.g. cognitive and physical function); or body system level (e.g. vascular and metabolic traits) that may be common risk factors for a number of major causes of death. This review shows there is growing evidence from large studies and systematic reviews that these individual characteristics, measured in pre-adult as well as the adult life, are associated with later mortality risk. The relative contribution of lifetime environment, genetic factors and chance, whether these contributions change with age, and the underlying social and biological pathways are still to be clarified. This review identifies areas where further life course research is warranted.

Abstract
OBJECTIVE To determine the prevalence of pediatric dyslipidemia in a large US medical insurance claims database and to compare the resulting estimate to the prevalence from the National Health and Nutrition Examination Survey (NHANES). PATIENTS AND METHODS Children 10-18 years old who had laboratory-defined dyslipidemia were identified from the Integrated Healthcare Information Services (IHCIS) database 2003-2006. For comparison purposes, the corresponding prevalence among the US children of same age was estimated from the NHANES 1999-2004 data. RESULTS Among the 273 064 children with at least one laboratory lipid value in the IHCIS database, 22.9% (n = 62 451) had laboratory-defined dyslipidemia. This prevalence was the same as the NHANES estimate (23.9%, 95%CI: 21.6-26.3). Elevated triglyceride (TG) was the most common type of dyslipidemia, detected among 13.2% of the IHCIS children and 14.2% of the US children, followed by elevated total cholesterol (TC), 7.7 and 9.6%, respectively. Among IHCIS dyslipidemic children, older teenage boys had higher rates than younger boys for high-density lipoprotein cholesterol (HDL-C) abnormality, but lower rates for elevated TC and low-density lipoprotein cholesterol (LDL-C). These age-related trends were also seen among NHANES dyslipidemic children. CONCLUSIONS Analyses of a population-based claims database revealed the same prevalence of pediatric dyslipidemia as that among the US children assessed in the NHANES data. Among dyslipidemic children in the claims database, the occurrence of specific dyslipidemias appeared to vary by age and gender, a trend that was also seen among the dyslipidemic children in the US.

Abstract
OBJECTIVE The purpose of this study was to examine the association between adiposity measures, ultrasound image quality, and preclinical markers of atherosclerosis in young adults. METHODS B-mode ultrasound was used to obtain common carotid intima-media thickness and common carotid artery distensibility of 2265 and 1313 adults aged 24 to 39 years in two population-based studies: the Cardiovascular Risk in Young Finns and Childhood Determinants of Adult Health studies. Qualitative assessments of ultrasound image quality were obtained from each study (scored as 1, excellent; 2, average; and 3, poor) based on the ability to detect arterial interfaces and the amount of noise present in the image. RESULTS Increased adiposity was associated with significantly increased odds (all P < .05) of average or poor carotid ultrasound image quality. Reduced image quality was associated with lower intima-media thickness in Young Finns (regression coefficient = -0.029; P = .01) and higher intima-media thickness in Childhood Determinants of Adult Health (regression coefficient = 0.013; P = .03) and lower distensibility levels in both studies (Young Finns, β = -.494; P < .01; Childhood Determinants of Adult Health: β = -.195; P < .01). We observed no differences (bias) in the association between adiposity measures and carotid intima-media thickness by image quality, but there was some evidence suggesting that the association between adiposity measures and carotid distensibility differed by image quality. CONCLUSIONS Adiposity affects ultrasound image quality and has the potential to bias associations between adiposity and preclinical markers of atherosclerosis. Studies examining adiposity and ultrasound-derived measures of atherosclerosis should consider taking steps during the design and analysis phase to adequately account for variations in image quality to avoid any potential bias.

Abstract
BACKGROUND Atherosclerosis has its roots in childhood. Therefore, defining the age when childhood risk exposure begins to relate to adult atherosclerosis may have implications for pediatric cardiovascular disease prevention and provide insights about the early determinants of atherosclerosis development. The aim of this study was to investigate the influence of age on the associations between childhood risk factors and carotid artery intima-media thickness, a marker of subclinical atherosclerosis. METHODS AND RESULTS We used data for 4380 members of 4 prospective cohorts-Cardiovascular Risk in Young Finns Study (Finland), Childhood Determinants of Adult Health study (Australia), Bogalusa Heart Study (United States), and Muscatine Study (United States)-that have collected cardiovascular risk factor data from childhood (age 3 to 18 years) and performed intima-media thickness measurements in adulthood (age 20 to 45 years). The number of childhood risk factors (high [highest quintile] total cholesterol, triglycerides, blood pressure, and body mass index) was predictive of elevated intima-media thickness (highest decile) on the basis of risk factors measured at age 9 years (odds ratio [95% confidence interval] 1.37 [1.16 to 1.61], P=0.0003), 12 years (1.48 [1.28 to 1.72], P<0.0001), 15 years (1.56 [1.36 to 1.78], P<0.0001), and 18 years (1.57 [1.31 to 1.87], P<0.0001). The associations with risk factors measured at age 3 years (1.17 [0.80 to 1.71], P=0.42) and 6 years (1.20 [0.96 to 1.51], P=0.13) were weaker and nonsignificant. CONCLUSIONS Our analyses from 4 longitudinal cohorts showed that the strength of the associations between childhood risk factors and carotid intima-media thickness is dependent on childhood age. On the basis of these data, risk factor measurements obtained at or after 9 years of age are predictive of subclinical atherosclerosis in adulthood.

Abstract
BACKGROUND The clinical utility of identifying pediatric metabolic syndrome (MetS) is controversial. This study sought to determine the status of pediatric MetS as a risk factor for adult subclinical atherosclerosis (carotid intima-media thickness [cIMT]) and type 2 diabetes mellitus (T2DM) and compare and contrast this prediction with its individual components. METHODS AND RESULTS Using data from the population-based, prospective, observational Bogalusa Heart and Cardiovascular Risk in Young Finns studies, we examined the utility of 4 categorical definitions of youth MetS and their components in predicting adult high cIMT and T2DM among 1781 participants aged 9 to 18 years at baseline (1984 to 1988) who were then examined 14 to 27 years later (2001-2007) when aged 24 to 41 years. Youth with MetS were at 2 to 3 times the risk of having high cIMT and T2DM as adults compared with those free of MetS at youth. Risk estimates with the use of high body mass index were similar to those of MetS phenotypes in predicting adult outcomes. Comparisons of area under the receiver operating characteristic curve and net reclassification index suggested that prediction of adult MetS, high cIMT, and T2DM in adulthood with the use of youth MetS was either equivalent or inferior to classification based on high body mass index or overweight and obesity. CONCLUSIONS Youth with MetS are at increased risk of meaningful adult outcomes; however, the simplicity of screening for high BMI or overweight and obesity in the pediatric setting offers a simpler, equally accurate alternative to identifying youth at risk of developing adult MetS, high cIMT, or T2DM.

Abstract
OBJECTIVE A 2008 report from the American Academy of Pediatrics recommended both population and individual approaches (including pharmacologic interventions) for adolescents who had low-density lipoprotein (LDL) cholesterol levels above various cutoff points (130, 160, and 190 mg/dL). However, the tracking and variability of these very high levels have not been investigated. METHODS A total of 6827 subjects underwent multiple LDL cholesterol determinations in childhood and adulthood in the Bogalusa Heart Study. The total number of determinations was 26748, and the median interval between examinations was 3 years. RESULTS Correlations between initial and subsequent LDL cholesterol levels ranged from r approximately 0.8 for measurements made within the same year to r approximately 0.5 for periods of > or = 20 years. Most children who had very high LDL cholesterol levels, however, had substantially lower levels at the next examination. LDL cholesterol levels between 160 and 189 mg/dL (n = 201) decreased, on average, by 21 mg/dL at the next examination, whereas levels of > or = 190 mg/dL (n = 44) decreased by 34 mg/dL. In contrast, the mean increase for LDL cholesterol levels of <70 mg/dL was 13 mg/dL. These changes were equal to those expected on the basis of regression to the mean. CONCLUSIONS There can be large changes in extreme levels of LDL cholesterol because of regression to the mean, and practitioners should be aware that very high levels may decrease substantially in the absence of any intervention.

Abstract
PURPOSE OF REVIEW To review the recent findings on evaluation and management of dyslipidemia in childhood and adolescence, giving a critical view on new therapeutic approaches. RECENT FINDINGS In 2008, the American Academy of Pediatrics released an updated policy statement recommending more frequent screening to detect dyslipidemia in childhood and the first-line use of statins in children with dyslipidemia who did not respond to lifestyle intervention and who were more than 8 years of age. These recommendations have caused a lot of controversy within the medical community and media. This debate is also sharpened by the fact that only few trials have investigated the long-term efficacy of statins on prevention of adult cardiovascular disease, their application in dyslipidemias other than familial hypercholesterolemia and the use of new pharmacological tools. SUMMARY The purpose of our paper could not be achieved clearly without a review of the physiology of cholesterol metabolism together with an analysis of causes of primary and secondary dyslipidemia affecting children. Moreover, recent knowledge on lipid-lowering therapy is reviewed.

Abstract
PURPOSE OF REVIEW Adolescence is a common time for the identification of cardiovascular disease risk factors, including elevated cholesterol. Guidelines for the detection and treatment of hypercholesterolemia differ for children and adults. This review highlights these differences and discusses special considerations for cholesterol management in the adolescent population. RECENT FINDINGS Several longitudinal studies have confirmed that the number of cardiovascular risk factors present in adolescence, including elevated cholesterol, lead to atherosclerosis in adults. There is increased awareness that other chronic medical conditions, including diabetes, congenital heart disease, inflammatory diseases, and childhood cancer, can accelerate this process. There is a move to screen and treat more young patients with elevated cholesterol to prevent future cardiovascular disease. New markers of atherosclerosis are being used to quantify cardiovascular disease risk in adolescents in research populations. The safety and efficacy of several interventions, including drug therapy, is increasingly established. SUMMARY Comprehensive cardiovascular risk assessment is important for adolescent health and includes assessment of family history and tobacco use along with measurement of body mass index and blood pressure. Additionally, cholesterol screening is recommended for overweight adolescents or those with an unknown family history and for all patients by the age of 20. Providers caring for adolescents should be familiar with both the pediatric and adult cholesterol screening and treatment guidelines as well as how common adolescent conditions affect cholesterol levels.

METHODS This retrospective cohort study used the claims data from the Integrated Healthcare Information Services (IHCIS), for the years 2003-2006. Two study cohorts consisted of children with laboratory-defined and diagnosis/treatment-defined dyslipidemia, respectively. They were compared to age- and gender-matched children without dyslipidemia, with respect to co-morbidities during the 6-month prior to and 12-month after the first dyslipidemic laboratory value or diagnosis/treatment. RESULTS Seven per cent of the children who had laboratory values available in the database had a cholesterol test during the study period. Only 15% of laboratory-defined children (n = 23,475) had a dyslipidemia diagnosis. Cholesterol-modifying medications were rarely prescribed. Substantially more laboratory-defined children than their comparators were obese (8 times), had diabetes mellitus (10 times), or had hypertension (5 times). These co-morbidities were even higher among diagnosis/treatment-defined children. CONCLUSIONS The rate of lipid testing among children was low. The ICD-9-CM diagnostic codes showed low sensitivity against laboratory definitions. Though only a small proportion of dyslipidemic children were diagnosed or treated with a medication, co-morbidities associated with dyslipidemia were common.

Abstract
PURPOSE OF REVIEW Nearing the end of the first decade of this new century, the challenges and changes in the field of outpatient pediatric cardiology continue to accelerate. RECENT FINDINGS To help the general pediatrician and family practice physician become aware of several new care guidelines and practice trends as well as the controversies surrounding them this article reviews recent publications and places them in a larger context. Current guidelines and policy statements for cardiovascular monitoring for children with attention deficit disorder, subacute bacterial endocarditis prophylaxis and follow-up of adults with congenital heart disease are discussed. Trends regarding use of echocardiograms, changing drug therapy for Marfan syndrome, follow-up of infant with complex coronary heart disease, and treatment of obesity are reviewed. SUMMARY It is important for the practicing pediatrician to be aware of these developments, so they can be incorporated into current patient care and increase the physician's ability to answer patient and family questions about these guidelines.

Abstract
Metabolic consequences of obesity including insulin resistance, type 2 diabetes mellitus, hyperlipidemia, hypertension, polycystic ovarian syndrome, and non-alcoholic fatty liver infiltration are rapidly emerging in the pediatric population. Identifying effective strategies for identifying and treating these obesity related comorbidities in children are crucial to the prevention of future cardiovascular disease and poor health outcomes.This review discusses the pathophysiologic connections between obesity, metabolic disease and cardiovascular risk. Current evidence and recommendations for screening and treatment for the metabolic consequences of pediatric obesity are reviewed.

Abstract
OBJECTIVE To examine how fitness in both childhood and adulthood is associated with adult obesity and insulin resistance. RESEARCH DESIGN AND METHODS A prospective cohort study set in Australia in 2004-2006 followed up a cohort of 647 adults who had participated in the Australian Schools Health and Fitness Survey in 1985 and who had undergone anthropometry and cardiorespiratory fitness assessment during the survey. Outcome measures were insulin resistance and obesity, defined as a homeostasis model assessment index above the 75th sex-specific percentile and BMI >or=30 kg/m(2), respectively. RESULTS Lower levels of child cardiorespiratory fitness were associated with increased odds of adult obesity (adjusted odds ratio [OR] per unit decrease 3.0 [95% CI 1.6-5.6]) and insulin resistance (1.7 [1.1-2.6]). A decline in fitness level between childhood and adulthood was associated with increased obesity (4.5 [2.6-7.7]) and insulin resistance (2.1 [1.5-2.9]) per unit decline. CONCLUSIONS A decline in fitness from childhood to adulthood, and by inference a decline in physical activity, is associated with obesity and insulin resistance in adulthood. Programs aimed at maintaining high childhood physical activity levels into adulthood may have potential for reducing the burden of obesity and type 2 diabetes in adults.

Abstract
OBJECTIVES This study was designed to determine which of the National Cholesterol Education Program or National Health and Nutrition Examination Survey low- and high-density lipoprotein cholesterol classifications of dyslipidemia status in adolescents is most effective at predicting high common carotid artery intima-media thickness (IMT) in adulthood. BACKGROUND Two classifications of pediatric dyslipidemia status have been proposed. No study has assessed which of these is most effective for predicting adolescents who will develop preclinical atherosclerosis in adulthood. METHODS Three population-based, prospective cohort studies collected lipoprotein measurements on 1,711 adolescents age 12 to 18 years who were remeasured as young adults age 29 to 39 years. Lipoproteins in adolescence were classified according to National Cholesterol Education Program and National Health and Nutrition Examination Survey cut points, and high IMT in adulthood was defined as those at or above the age-, sex-, race-, and cohort-specific 90th percentile of IMT. RESULTS Independent of the classification employed, adolescents with dyslipidemia were at significantly increased risk of having high IMT in adulthood (relative risks from 1.6 to 2.5). Differences in predictive capacity between both classifications were minimal. Overweight or obese adolescents with dyslipidemia had increased carotid IMT (males: 0.11 mm; females: 0.08 mm) in adulthood compared with those who did not have both risk factors. Adolescent dyslipidemia status was more strongly associated with high IMT in adulthood than change in dyslipidemia status. CONCLUSIONS Pediatric dyslipidemia classifications perform equally in the prediction of adolescents who are at increased risk of high IMT in young adulthood. Our data suggest that dyslipidemia screening could be limited to overweight or obese adolescents.
