Abstract
The association between hypertension in adulthood and cardiovascular morbidity and death is well known. Based on that association, a diagnosis of elevated blood pressure in children has been clinically interpreted as early cardiovascular disease. The objective of this review is to discuss historical data and new research on the relationship between elevated blood pressure and early preclinical and later adult cardiovascular disease. After summarizing the evidence, we will address the gaps in knowledge around Pediatric hypertension in an effort to stimulate research into the important role that control of blood pressure in youth may play in preventing adult cardiovascular disease.

Pyles LA, Lilly CL, Joseph A, Mullett CJ, Neal WA. Cardiometabolic risk factors in siblings from a statewide screening program. J Clin Lipidol 2020; 14:762-771. [PMID: 33067145 DOI: 10.1016/j.jacl.2020.09.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2020] [Revised: 09/08/2020] [Accepted: 09/09/2020] [Indexed: 11/28/2022]
Abstract
BACKGROUND The Coronary Artery Risk Detection in Appalachian Communities (CARDIAC) Project is a state-wide risk factor screening program that operated in West Virginia for 19 years and screened more than 100,000 5th graders for obesity, hypertension, and dyslipidemia. OBJECTIVES We investigated siblings in the CARDIAC Project to assess whether cardiometabolic risk factors (CMRFs) correlate in siblings. METHODS We identified 12,053 children from 5752 families with lipid panel, blood pressure, and anthropometric data. A linkage application (LinkPlus from the U.S. Centers for Disease Control and Prevention) matched siblings based on parent names, addresses, telephone numbers, and school to generate a linkage probability curve. Graphical and statistical analyses demonstrate the relationships between CMRFs in siblings. RESULTS Siblings showed moderate intraclass correlation coefficient of 0.375 for low-density lipoprotein cholesterol (LDL-C), 0.34 for high-density lipoprotein cholesterol (HDL-C), and 0.22 for triglyceride levels. The body mass index (BMI) intraclass correlation coefficient (0.383) is slightly better (2%) than LDL-C or HDL-C, but the standardized beta values from linear regression suggest a 3-fold impact of sibling LDL-C over the child's own BMI. The odds ratio of a second sibling having LDL-C < 110 mg/dL with a first sibling at that level is 3.444:1 (Confidence Limit 3.031-3.915, P < .05). The odds ratio of a sibling showing an LDL-C ≥ 160 mg/dL, given a first sibling with that degree of elevated LDL-C is 29.6:1 (95% Confidence Limit: 15.54-56.36). The individual LDL-C level correlated more strongly with sibling LDL-C than with the individual's own BMI. Seventy-eight children with LDL-C > 160 mg/dL and negative family history would have been missed, which represents more than half of those with LDL-C > 160 mg/dL (78 vs 67 or 54%). CONCLUSIONS Sibling HDL-C levels, LDL-C levels, and BMIs correlate within a family. Triglyceride and blood pressure levels are less well correlated. The identified CMRF relationships strengthen the main findings of the overall CARDIAC Project: an elevated BMI is not predictive of elevated LDL-C and family history of coronary artery disease poorly predicts cholesterol abnormality at screening. Family history does not adequately identify children who should be screened for cholesterol abnormality. Elevated LDL-C (>160 mg/dL) in a child strongly suggests that additional siblings and parents be screened if universal screening is not practiced.

Abstract
Obesity, a chronic inflammatory disease, is the most prevalent modifiable risk factor for cardiovascular disease. The mechanisms underlying inflammation in obesity are incompletely understood. Recent developments have challenged the dogma of immunological memory occurring exclusively in the adaptive immune system and show that the innate immune system has potential to be reprogrammed. This innate immune memory (trained immunity) is characterized by epigenetic and metabolic reprogramming of myeloid cells following endogenous or exogenous stimulation, resulting in enhanced inflammation to subsequent stimuli. Trained immunity phenotypes have now been reported for other immune and non-immune cells. Here, we provide a novel perspective on the putative role of trained immunity in mediating the adverse cardiovascular effects of obesity and highlight potential translational pathways.

Abstract
This review presents a retrospective analysis of the significance of the contributions of pathologists and kindred investigators in the latter half of the twentieth century to the advancement of understanding of atherosclerosis, a major disease and affliction of humankind. These outstanding investigators contributed importantly to the development of a large body of evidence encompassing population-based autopsy studies, experimental animal studies and cell biological investigations that, coupled with insights from epidemiological studies, serve as the underpinning for the current dominant response to injury theory of atherogenesis. Their collective contributions have been highly meritorious and will remain seminally important into the future.

Abstract
Background: There is growing evidence that non-alcoholic fatty liver disease (NAFLD) is a disease affecting not only the liver but also extrahepatic organs. Aim: To investigate whether in youths NAFLD is associated with extrahepatic complications such as subclinical atherosclerosis, cardiac abnormalities, hypertension, type 2 diabetes, decreased bone mineral density, renal dysfunction, obstructive sleep apnea, and polycystic ovary syndrome. Methods: We systematically reviewed PubMed; Scopus; Embase; and the Cochrane Library databases up to 28 February 2019 and assessed the quality of studies using the Newcastle-Ottawa Scale. Results: Thirty-five articles were selected for this systematic review: fifteen (4627 participants) evaluated the association of NAFLD with subclinical atherosclerosis; four (969 participants) with cardiac abnormalities; two (550 participants) with hypertension; four (1328 participants) with diabetes; six (523 participants) with low bone mineral density; two (865 participants) with renal dysfunction; one with obstructive sleep apnea; and one with polycystic ovary syndrome. Most studies found that youths with NAFLD have increased features of subclinical atherosclerosis; as well as of cardiac alterations. Limited data were available to endorse a solid estimate of the prevalence of diabetes; low mineral density and renal dysfunction in the pediatric NAFLD population. Conclusion: NAFLD-related intermediate CVD outcomes can occur and be detected early in young populations.

Abstract
OBJECTIVE The development of these guidelines is mandated by the American Association of Clinical Endocrinologists (AACE) Board of Directors and American College of Endocrinology (ACE) Board of Trustees and adheres with published AACE protocols for the standardized production of clinical practice guidelines (CPGs). METHODS Recommendations are based on diligent reviews of the clinical evidence with transparent incorporation of subjective factors, according to established AACE/ACE guidelines for guidelines protocols. RESULTS The Executive Summary of this document contains 87 recommendations of which 45 are Grade A (51.7%), 18 are Grade B (20.7%), 15 are Grade C (17.2%), and 9 (10.3%) are Grade D. These detailed, evidence-based recommendations allow for nuance-based clinical decision-making that addresses multiple aspects of real-world medical care. The evidence base presented in the subsequent Appendix provides relevant supporting information for Executive Summary Recommendations. This update contains 695 citations of which 203 (29.2 %) are EL 1 (strong), 137 (19.7%) are EL 2 (intermediate), 119 (17.1%) are EL 3 (weak), and 236 (34.0%) are EL 4 (no clinical evidence). CONCLUSION This CPG is a practical tool that endocrinologists, other health care professionals, health-related organizations, and regulatory bodies can use to reduce the risks and consequences of dyslipidemia. It provides guidance on screening, risk assessment, and treatment recommendations for a range of individuals with various lipid disorders. The recommendations emphasize the importance of treating low-density lipoprotein cholesterol (LDL-C) in some individuals to lower goals than previously endorsed and support the measurement of coronary artery calcium scores and inflammatory markers to help stratify risk. Special consideration is given to individuals with diabetes, familial hypercholesterolemia, women, and youth with dyslipidemia. Both clinical and cost-effectiveness data are provided to support treatment decisions.

Cardiovascular events in patients under age fifty with early findings of elevated lipid and glucose levels - The AMORIS study. PLoS One 2018; 13:e0201972.

Abstract
Background The long-term trajectories of lipid and glucose levels in subjects who experience a major cardiovascular (CV) event at a young age has not been well studied. Our objective was to investigate lipid, lipoprotein, apolipoprotein (apo), and glucose levels in individuals experiencing a CV event before 50 years of age. Methods and findings A first CV event [non-fatal myocardial infarction (MI), coronary revascularisation, or CV related death] before age 50 was recorded in 2,939 (cumulative incidence 1.2% in males and 0.3% in females) of 361,353 individuals included in the prospective Swedish AMORIS (Apolipoprotein-related MOrtality RISk) study with health examinations 1985–1996 and follow-up through 2011. In a nested case-control analysis, cases with a CV event were matched to randomly selected controls. Population risk factor trajectories were calculated up to 20 years prior to an event. Total cholesterol (TC), triglyceride (TG), and glucose levels were higher in cases than in controls as early as 20 years prior to the event with differences increasing over time. Low density lipoprotein, apoB, and the apoB/apoA-1 ratio were higher and increased over time, while HDL and apoA-1 were lower in cases compared to controls. The odds ratio was 2.5 (95% confidence interval 1.6–3.7) for TC ≥5 mmol/L and TG ≥1.7 mmol/L in cases versus controls. The adjusted population-attributable fractions including lipids, glucose, diabetes, smoking, hypertension, and obesity indicated that about 50% of CV events before age 50 may be associated with elevated lipid and glucose levels. Conclusions Elevated TC, TG, LDL, apoB, and glucose levels and high apoB/apo A-1 ratio documented two decades before a CV event in subjects younger than 50 years may account for about half of CV events before age 50, which calls for early recognition and possibly treatment of modifiable CV risk factors in young individuals.

Abstract
Short stature is associated with increased LDL-cholesterol levels and coronary artery disease in adults. We investigated the relationship of stature to LDL levels in children in the West Virginia Coronary Artery Risk Detection in Appalachian Communities (CARDIAC) Project to determine whether the genetically determined inverse relationship observed in adults would be evident in fifth graders. A cross-sectional survey of schoolchildren was assessed for cardiovascular risk factors. Data collected at school screenings over 18 years in WV schools were analyzed for 63,152 fifth-graders to determine relationship of LDL to stature with consideration of age, gender, and BMI. The first (shortest) quartile showed an LDL level of 93.6 mg/dl compared with an LDL level of 89.7 mg/dl for the fourth (tallest) quartile. Each incremental increase of 1 SD of height lowered LDL by 0.049 mg/dl (P < 0.0001). Multivariate analysis showed LDL to vary inversely as a function of the first (lowest) quartile of height after controlling for gender, median age, BMI percentile for age and gender, and year of screening. The odds ratio for LDL ≥ 130 mg/dl for shortest versus tallest quartile is 1.266 (95% CL 1.162-1.380). The odds ratio for LDL ≥ 160 mg/dl is 1.456 (95% CL 1.163-1.822). The relationship between short stature and LDL, noted in adults, is confirmed in childhood.

Abstract
OBJECTIVES: The number of deaths from vascular diseases is incredibly high worldwide, and reliable markers for major events are still needed. The current cross-sectional study investigated the association of Klotho haplotypes and Klotho serum levels with classic risk factors and a clinical history of vascular events. METHODS: Clinical, anthropometric, biochemical and nutritional assessments were conducted with 168 older adults, complemented by genotyping (rs9536314 and rs9527025) and the detection of serum Klotho (ELISA). RESULTS: Klotho levels and haplotypes did not associate with most classic risk factors for vascular events, including markers such as C-reactive protein and homocysteine. A positive association was only found between Klotho levels and the previous occurrence of a myocardial infarction by both correlational (p=0.006) and variance analyses (p<0.001), and these associations were independent of the context. CONCLUSION: Our results suggest that serum Klotho is higher in individuals with a clinical history of myocardial infarction but not with a history of coronary artery disease or stroke. None of the Klotho haplotypes were associated with the variables investigated herein.

Abstract
The cardiometabolic syndrome is highly prevalent among overweight youth. The risk of developing the cardiometabolic syndrome is likely triggered or exacerbated by concurrent obesity, unhealthy lifestyle/eating habits, and hormonal changes (puberty). Current screening recommendations include measurement of blood pressure, fasting insulin and glucose, and total cholesterol. However, limiting assessments to these measures underestimates cardiometabolic risk in overweight youth, particularly minorities. Early identification of cardiometabolic risk in its incipient stages may justify early and more aggressive intervention to prevent progression and complications. This review provides rationale for additional assessments to determine cardiometabolic risk in overweight youth and recommends treatment options.

Abstract
Second-generation antipsychotics (SGAs) are increasingly being used to treat children for a range of mental health conditions, for example, anxiety disorder, attention deficit hyperactivity disorder and bipolar disorder. SGA treatment is associated with weight gain and cardiometabolic side effects such as dyslipidemia, insulin resistance and elevated blood pressure, in some, but not all children. This review provides an overview of the potential role of pharmacogenomics in predisposing a child to unhealthy weight gain and cardiometabolic side effects with SGA treatment. Specifically, the review includes a synopsis of the evidence for cardiometabolic side effects in SGA-treated children, illustrating the extent and depth of the problem; summarizes the potential long-term consequences of developing cardiometabolic risk during childhood and highlights genetic variants that may be useful in predicting cardiometabolic side effects in SGA-treated children.

Abstract
Elevated blood pressure has been demonstrated to track from youth to adulthood and some have demonstrated an association between early-life blood pressure and subsequent atherosclerosis and cardiovascular disease. In addition, reports regarding the strength of tracking are inconsistent and the modifiable risk factors that affect the trajectory of blood pressure from youth to adulthood remain unclear. This paper comprehensively evaluated the existing classifications of youth hypertension and the current trends of youth hypertension. Further, evidence for the consequences of hypertension in youth has been comprehensively evaluated. Importantly, a review of the studies examining tracking from youth to adulthood has been performed and a number of studies investigating the factors affecting tracking has also been investigated. The overall consideration of this body of literature highlights the vital importance of identifying hypertension in youth to prevent complications in adulthood. Adiposity is regarded to be a factor affecting the progression of hypertension from youth to adulthood yet there is little evidence available for other modifiable factors. It is apparent that further research is necessary within this field in order to create effective preventative strategies to target youth hypertension.

Abstract
The epidemic of childhood obesity worldwide has led to increased incidence of the metabolic syndrome and type 2 diabetes in the pediatric and adolescent population. As such, there is increasing concern that this large population of children is at risk for the long-term complications of diabetes, specifically cardiovascular disease. With cardiovascular disease remaining the leading cause of death in adults, this presents a significant public health concern as these children age. In this article, we discuss cardiovascular disease and risk in children and adolescents with type 2 diabetes, including the epidemiology of type 2 diabetes, atherosclerotic cardiovascular disease, obesity, hypertension, and left ventricular function.

Abstract
Obesity-related cardiovascular disease in children is becoming more prevalent in conjunction with the rise in childhood obesity. Children with obesity are predisposed to an increased risk of cardiovascular morbidity and mortality in adulthood. Importantly, research in children with obesity over the last decade has demonstrated that children may exhibit early signs of cardiovascular dysfunction as a result of their excess adiposity, often independent of other obesity-related comorbidities such as dyslipidemia and insulin resistance. The clinical evidence is accumulating to suggest that the cardiovascular damage, once observed only in adults, is also occurring in obese children. The objective of this review is to provide a synopsis of the current research on cardiovascular abnormalities in children with obesity and highlight the importance and need for early detection and prevention programs to mitigate this potentially serious health problem.

Abstract
In recent years, childhood obesity is becoming an epidemic health problem. It is now evident from many studies that childhood obesity is correlated with adult excess weight status and the development of risk factors for cardiovascular diseases in adulthood, including hypertension, type 2 diabetes mellitus, dyslipidemia, and metabolic syndrome. The exposure to obesity and to the above risk factors during childhood subsequently lead to atherosclerotic development, such as altered vascular structure and function, although the mechanisms are still unclear. Several non-invasive, and thus easy-to-obtain measures of arterial structure and function, have been shown to be clinically useful in providing information about vasculature early in the course of atherosclerosis, including measurement of endothelial function, carotid intima media thickness, and arterial stiffness. The early detection of cardiovascular abnormalities is essential because the control of the atherogenic process is more effective during its early stages. The present review focuses on the cardiovascular consequences of obesity, on the mechanisms and the methods of measurement of endothelial dysfunction in obese children and adolescents, and on the ways of intervention for the improvement of vascular health.

Abstract
BACKGROUND The American Heart Association recently developed definitions and metrics for monitoring the spectrum of cardiovascular health in adolescents and children. Current nationally representative prevalence estimates according to sex and race/ethnicity are unavailable. METHODS AND RESULTS We examined the components of cardiovascular health in 4673 participants aged 12 to 19 years (representing ≈33.2 million US adolescents) from the 2005-2010 National Health and Nutrition Examination Surveys. Population prevalence of individual cardiovascular health behaviors and factors was estimated according to American Heart Association criteria for poor, intermediate, and ideal levels. Ideal blood pressure was most prevalent (males, 78%; females, 90%), whereas a dramatically low prevalence of ideal Healthy Diet Score was observed (males, <1%; females, <1%). Females exhibited a lower prevalence of ideal total cholesterol (65% versus 72%, respectively) and ideal physical activity levels (44% versus 67%, respectively) yet a higher prevalence of ideal blood glucose (89% versus 74%, respectively) compared with males. Approximately two thirds of adolescents exhibited ideal body mass index (males, 66%; females, 67%) and ideal smoking status (males, 66%; females, 70%). Less than 50% of adolescents exhibited ≥5 ideal cardiovascular health components (45%, males; 50%, females). Prevalence estimates according to sex were consistent across race/ethnic groups. CONCLUSIONS The low prevalence of ideal cardiovascular health behaviors in US adolescents, particularly physical activity and dietary intake, will likely contribute to a worsening prevalence of obesity, hypertension, hypercholesterolemia, and dysglycemia as the current US adolescent population reaches adulthood. Population-wide emphasis on establishment of ideal cardiovascular health behaviors early in life is essential for maintenance of ideal cardiovascular health throughout the lifespan.

Abstract
Background Atherosclerosis (AT) is a chronic inflammatory disease characterized by the accumulation of inflammatory cells, lipoproteins and fibrous tissue in the walls of arteries. AT is the primary cause of heart attacks and stroke and is the leading cause of death in Western countries. To date, the pathogenesis of AT is not well-defined. Studies have shown that the dedifferentiation of contractile and quiescent vascular smooth muscle cells (SMC) to the proliferative, migratory and synthetic phenotype in the intima is pivotal for the onset and progression of AT. To further delineate the mechanisms underlying the pathogenesis of AT, we analyzed the early molecular pathways and networks involved in the SMC phenotype transformation. Methods Quiescent human coronary artery SMCs were treated with minimally-oxidized LDL (moxLDL), for 3 hours and 21 hours, respectively. Transcriptomic data was generated for both time-points using microarrays and was subjected to pathway analysis using Gene Set Enrichment Analysis, GeneMANIA and Ingenuity software tools. Gene expression heat maps and pathways enriched in differentially expressed genes were compared to identify functional biological themes to elucidate early and late molecular mechanisms of moxLDL-induced SMC dedifferentiation. Results Differentially expressed genes were found to be enriched in cholesterol biosynthesis, inflammatory cytokines, chemokines, growth factors, cell cycle control and myogenic contraction themes. These pathways are consistent with inflammatory responses, cell proliferation, migration and ECM production, which are characteristic of SMC dedifferentiation. Furthermore, up-regulation of cholesterol synthesis and dysregulation of cholesterol metabolism was observed in moxLDL-induced SMC. These observations are consistent with the accumulation of cholesterol and oxidized cholesterol esters, which induce proinflammatory reactions during atherogenesis. Our data implicate for the first time IL12, IFN-α, HGF, CSF3, and VEGF signaling in SMC phenotype transformation. GPCR signaling, HBP1 (repressor of cyclin D1 and CDKN1B), and ID2 and ZEB1 transcriptional regulators were also found to have important roles in SMC dedifferentiation. Several microRNAs were observed to regulate the SMC phenotype transformation via an interaction with IFN-γ pathway. Also, several “nexus” genes in complex networks, including components of the multi-subunit enzyme complex involved in the terminal stages of cholesterol synthesis, microRNAs (miR-203, miR-511, miR-590-3p, miR-346*/miR- 1207-5p/miR-4763-3p), GPCR proteins (GPR1, GPR64, GPRC5A, GPR171, GPR176, GPR32, GPR25, GPR124) and signal transduction pathways, were found to be regulated. Conclusions The systems biology analysis of the in vitro model of moxLDL-induced VSMC phenotype transformation was associated with the regulation of several genes not previously implicated in SMC phenotype transformation. The identification of these potential candidate genes enable hypothesis generation and in vivo functional experimentation (such as gain and loss-of-function studies) to establish causality with the process of SMC phenotype transformation and atherogenesis.

Abstract
OBJECTIVE To estimate the prevalence of metabolic syndrome among adolescents attending school in the Jammu region, India. MATERIALS AND METHODS This is a cross-sectional study conducted between November 2009 and December 2010, among a total of 1160 school-going adolescents of both sexes aged 10-18 years. Relevant metabolic and anthropometric variables were analyzed and criteria suggested by National Cholesterol Education Program Adult Treatment Panel Third (NCEP-ATP III) modified forage was used to define metabolic syndrome. RESULTS The overall prevalence of metabolic syndrome was 2.6%. Prevalence of metabolic syndrome was higher in males (3.84%) than in females (1.6%) and slightly higher in urban area (2.80%) than in rural area (2.52%), whereas prevalence of metabolic syndrome among centrally obese subjects was as high as 33.33%. High density lipoprotein cholesterol was the most common and high blood pressure was the least common constituent of metabolic syndrome. Metabolic syndrome was most prevalent in 16-18 years age group (4.79%). CONCLUSION This study demonstrates that metabolic syndrome phenotype exists in substantial number (up to 3%) of adolescent population in the Jammu region, India, and particularly 33% of obese adolescents are at risk to develop metabolic syndrome. These findings pose a serious threat to the current and future health of these young people.

Abstract
OBJECTIVE To establish normative data for lipoprotein subfractions using a novel ion mobility assay in healthy lean children and to compare their data with those of obese children preselected with normal glucose, blood pressure, and relatively normal lipids. STUDY DESIGN Fasting blood samples in 162 children aged 7.0-18.9 years (75 lean [body mass index: 18.6 ± 6.6 kg/m(2)] and 87 obese [body mass index: 31.7 ± 5.4 kg/m(2)]) were analyzed. Correlation of lipoprotein subfractions with anthropometric and laboratory markers was performed. Principal component analysis was used to avoid using correlated variables. RESULTS Normative data for lipid subfractions were obtained in healthy children. Lean children had higher high-density lipoprotein (HDL)-large (76%), HDL-small (13%), and HDL-total (27%) compared with obese (P < .01), and lower low-density lipoprotein (LDL)-medium (-30%, P < .01) and medium + small (-21%, P = .02) as well as LDL-total (-13%, P = .035). In both groups, the LDL component was higher in males and pubertal children (P < .01). Prepubertal children had a higher HDL component than pubertal ones (P < .004). Adjusting for sex and pubertal status LDL component was positively, and HDL component negatively, correlated with obesity (P < .004). CONCLUSIONS Despite relatively normal triglycerides and cholesterol measured with standard assays at screening, ion mobility analysis showed significant differences in lipid and apolipoprotein subfractions between lean and obese children, even those prepubertal. Long-term, prospective follow-up may better characterize the predictability of lipid subfractions for future cardiovascular disease risk in children.

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.

Abstract
In the last 50 years, obesity has become a global epidemic and is one of the main public health problems in many parts of the world. Adolescence is a critical period regarding weight control. The factors determining obesity include a complex group of interrelated biological, behavioral and environmental factors which reinforce each other. In children and adolescents, obesity is associated with premature cardiovascular diseases, diabetes mellitus type 2, acanthosis nigricans, respiratory and skeletal muscle problems, as well as psychological problems. The clinical manifestations of cardiovascular disease begin in middle age. Nevertheless, studies indicate that the atherosclerotic process begins to develop during childhood. Postprandial hyperlipemia is a physiological process that occurs several times a day after the complete absorption of a diet including lipids and has been suggested as a risk factor for coronary heart disease (CHD). New study areas include the effects of different fatty acids, lipid sources (endogenous and exogenous), and the effect ingesting alcoholic beverages during meals. Given the evidence that postprandial lipidemia is an independent risk factor for CHD, it is vital to establish normative values for children and adolescents such that more effective and efficient preventive and therapeutic measures can be adopted.

Abstract
OBJECTIVES Several studies have shown that causes of adult hypertension arise in childhood, and obesity may be a potential cause or at least a mitigating factor in this development. Body mass index is a well studied obesity metric, yet other potential adiposity measures such as percent body fat and waist circumference have been somewhat less considered. The purpose of this study is to determine associations between these alternative serial childhood adiposity measures and adulthood blood pressure. METHODS Measurements from participants in the Fels Longitudinal Study were used to summarize childhood adiposity, represented by childhood measurements of percent body fat and height-adjusted waist circumference. These subjects also provided systolic and diastolic blood pressure as adults. Childhood adiposity levels were categorized as high or low as compared to the respective upper quartile, and associations with adult blood pressure were measured using Poisson regression to estimate the number of expected occurrences of elevated adiposity during childhood. Adult lifestyle covariates and adiposity were accounted for using multiple linear regression. RESULTS Summary indices of the childhood adiposity measures were significantly associated with both adult blood pressure metrics in men and women, though some of these associations were altered or reduced in the presence of adult lifestyle characteristics and adult adiposity measures. CONCLUSIONS Childhood measures of percent body fat and height-adjusted waist circumference have an effect on adult blood pressure, though the effect can be mitigated by adult lifestyles.

Abstract
Background Risk factors in childhood create a life-long burden important in the development of cardiovascular (CV) disease in adulthood. Many risk factors for CV disease (e.g., hypertension) also increase the risk of renal disease. However, the importance of childhood risk factors on the development of chronic kidney disease and end-stage renal disease (ESRD) is not well characterized. Methods The current observations include data from Bogalusa Heart Study participants who were examined multiple times as children between 1973 and 1988. Results Through 2006, fifteen study participants subsequently developed ESRD in adulthood; seven with no known overt cause. Although the Bogalusa Heart Study population is 63% white and 37% black and 51% male and 49% female, all seven ESRD cases with no known overt cause were black males (p < 0.001). Mean age-adjusted systolic and diastolic blood pressure in childhood was higher among the ESRD cases (114.5 mmHg and 70.1 mmHg, respectively) compared to black (103.0 mmHg and 62.3 mmHg, respectively) and white (mean = 103.3 mmHg and 62.3 mmHg, respectively) boys who didn't develop ESRD. The mean age-adjusted body mass index in childhood was 23.5 kg/m2 among ESRD cases and 18.6 kg/m2 and 18.9 kg/m2 among black and white boys who didn't develop ESRD, respectively. Plasma glucose in childhood was not significantly associated with ESRD. Conclusion These data suggest black males have an increased risk of ESRD in young adulthood. Elevated body mass index and blood pressure in childhood may increase the risk for developing ESRD as young adults.

Abstract
BACKGROUND The American Academy of Pediatrics (AAP) criterion for screening for hypercholesterolemia in children is family history of hypercholesterolemia or cardiovascular disease or BMI > or =85th percentile. This paper aims to determine the sensitivity, specificity, and positive predictive value (PPV) of dyslipidemia screening using AAP criteria along with either family history or BMI. METHODS Height, weight, plasma total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides, and family history were obtained for 678 children aged 8, 11, and 14 years, enrolled from 1991 to 1993 in Project HeartBeat!. Sensitivity, specificity, and PPV screening of each lipid component using family history alone, BMI > or =85th percentile alone, or family history and/or BMI > or =85th percentile, were calculated using 2008 AAP criteria (total cholesterol, LDL-C, and triglycerides > or =90th percentile; HDL-C <10th percentile). RESULTS Sensitivity of detecting abnormal total cholesterol, LDL-C, HDL-C, and triglycerides using family history alone ranged from 38% to 43% and significantly increased to 54%-66% using family history and/or BMI. Specificity significantly decreased from approximately 65% to 52%, and there were no notable changes in PPV. In black children, cholesterol screening using the BMI > or =85th percentile criterion had higher sensitivity than when using the family history criterion. In nonblacks, family history and/or BMI > or =85th percentile had greater sensitivity than family history alone. CONCLUSIONS When the BMI screening criterion was used along with the family history criterion, sensitivity increased, specificity decreased, and PPV changed trivially for detection of dyslipidemia. Despite increased screening sensitivity by adding the BMI criterion, a clinically significant number of children still may be misclassified.

Abstract
BACKGROUND Associations among dietary intake, physical activity, and cardiovascular disease (CVD) risk factors are inconsistent among male and female youth, possibly from lack of adjustment for pubertal status. The purpose of this report is to describe the associations of CVD risk factors among youth, adjusted for sexual maturation. METHODS Data analyzed in 2007 from a sumsample of 556 children aged 8, 11, and 14 years in Project HeartBeat!, 1991-1993, provide cross-sectional patterns of CVD risk factors by age and gender, adjusting for sexual maturation, within dietary fat and physical activity categories. RESULTS Girls consuming moderate- to high-fat diets were significantly less physically active than those consuming low-fat diets. Boys and girls consuming high-fat diets had higher saturated fat and cholesterol intakes than children in low-fat categories. Boys had no significant differences in physical activity, blood pressure, waist circumference, or plasma cholesterol levels across fat categories. Girls' plasma cholesterol levels showed no significant differences across fat categories. Dietary intake did not differ across moderate-to-vigorous physical activity (MVPA) categories within gender. There were no differences in BMI by fat or MVPA categories for either gender. Girls' waist circumference differed significantly by fat category, and systolic blood pressure differed significantly across fat and MVPA categories. Boys' fifth-phase diastolic blood pressure was significantly different across MVPA categories. CONCLUSIONS Girls consuming atherogenic diets were significantly less physically active than those with low fat intakes, whereas boys consuming high-fat diets did not show differences in physical activity measures. With the prevalence of overweight rising among youth, the impact of atherogenic diets and sedentary lifestyles on CVD risk factors is of concern to public health professionals.

Am J Prev Med 2009; 37:S56-64.

Abstract
BACKGROUND Longitudinal data on the normal development of blood lipids and its relationships with body fatness in children and adolescents are limited. Objectives of the current analysis were to estimate trajectories related to age for four blood lipid components and to examine the impact of change in body fatness on blood lipid levels, comparing estimated effects among adiposity indices, in children and adolescents. METHODS Three cohorts, with a total of 678 children (49.1% female, 79.9% nonblack) initially aged 8, 11, and 14 years, were followed at 4-month intervals (1991-1995). Total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglyceride levels were determined in blood samples taken following fasting. Body fatness was measured by five adiposity indices-BMI; percent body fat (PBF); abdominal circumference; and the sums of six and of two skinfold thicknesses. Trajectories of change in blood lipid levels from ages 8 to 18 years were estimated by gender and race. The impact of change in body fatness on lipid levels was evaluated for each index, adjusting for gender, race, and age. RESULTS All lipid components varied significantly with age. Total cholesterol decreased by approximately 19 mg/dL from ages 9 to 16 years in girls and more steeply from ages 10 to 17 years in boys. LDL-C decreased monotonically, more steeply in boys than in girls. It was higher among nonblacks than among blacks. HDL-C increased monotonically in girls, mainly from ages 14 to 18 years, but fluctuated sharply among boys. Levels of HDL-C were higher among blacks than among nonblacks. The levels of triglycerides increased from ages 8 to 12 years among girls and, almost linearly, from ages 8 to 18 years among boys. The levels of triglycerides were higher among nonblacks than among blacks. Increase in body fatness was significantly associated with increases in total cholesterol, LDL-C, and triglyceride levels. Significant interactions between the adiposity indices (except for BMI) and gender indicated smaller impacts of change in body fatness on total cholesterol and LDL-C in girls than in boys. The estimated impact on triglycerides was weaker among blacks than among nonblacks, except for PBF. Change in body fatness was negatively associated with HDL-C. The results remained essentially unchanged after adjustments for energy intake, physical activity, and sexual maturation. CONCLUSIONS Patterns of change with age in blood lipid components vary significantly among gender and racial groups. Increase in body fatness among children is consistently associated with adverse change in blood lipids. Evaluation of blood lipid level should take into account variation by age, gender, and race. Intervention through body-fat control should help prevent adverse lipid levels in children and adolescents.

Abstract
OBJECTIVE We assessed the prevalence, socioeconomic distribution and clustering of five major chronic disease behavioral risk factors (physical inactivity, sedentary behavior, tobacco smoking, alcohol drinking and high body mass index) in a representative sample of Canadian children and adolescents aged 10-17 years. METHODS Cross-sectional data (n=4724) from Cycle 4 (2000/2001) of the National Longitudinal Survey of Children and Youth were used. Clustering was assessed using an observed to expected ratio method. RESULTS Overall, 65% of Canadian youth had two or more behavioral risk factors compared to only 10% with none of the five risk factors. The prevalence of having multiple behavioral risk factors was greater among older youth and those from low socioeconomic status families. Behavioral risk factors clustered in multiple combinations. Specifically, the simultaneous occurrence of all five risk factors was 120% greater in males (Observed/Expected ratio: 2.20; 95% CI: 1.31-3.09) and 94% greater in females (Observed/Expected ratio: 1.94; 95% CI: 1.24-2.64) than expected. Ever smoking and ever drinking showed the strongest association among the pairwise clusters. CONCLUSIONS Multiple chronic disease behavioral risk factors are frequent and occur more often than expected among Canadian children and adolescents. Early prevention programs targeting clusters of behavioral risk factors in youth are needed.

Abstract
Objective: This paper reports the frequency, type, and degree of dyslipidemia in obese children before therapeutic intervention. The relationships between lipid values and weight status, as well as lipid values and physical fitness, of these children were also investigated. Design and methods: The initial examination of the Freiburg Intervention Trial for Obese Children (FITOC) measured the values of triglycerides (TG), total cholesterol (C), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) in 546 obese children aged 7–12 (body mass index [BMI] > 97th percentile), and compared these values with those of the age- and sex-specific reference group in the Lipid Research Clinics Population Studies Data Book (LRC). Four groups were selected according to the following scheme: A, Normolipidemia; B, Hyper-LDL-cholesterolemia alone; C, Hypo-HDL-C + hypertriglyceridemia; D, Combined hyperlipidemia = Hyper-LDL-C + hypertriglyceridemia. Body mass index, BMI-SDS (corrected BMI), and physical performance in watt/kg body weight were measured. Results: A total of 45.8% of the overweight children showed an abnormal lipid profile. Ten percent of the children had high LDL-C levels (group B), while 15% had increased LDL-C and increased TG (group D) (higher prevalence in boys). In 18.9% we found increased TG, combined with decreased HDL-C values (group C). Conclusion: Obese children are at risk of dyslipoproteinemia and related diseases. Children with the highest BMI-SDS and lowest physical fitness have the lowest HDL-C values and increased TG, indicating a higher risk for the metabolic syndrome.

Abstract
OBJETIVOS: Avaliar a associação entre obesidade e dislipidemias em adolescentes do ensino público e privado de Campina Grande-PB, Brasil. MÉTODOS: Estudo transversal com 180 adolescentes de 14 a 17 anos matriculados no ensino público e privado de Campina Grande-PB. O estado nutricional foi classificado segundo os percentis do Índice de Massa Corporal para sexo e idade. Foi realizada coleta sangüínea para avaliação do perfil lipídico (colesterol total, frações HDL-colesterol, LDL-colesterol e triglicerídeos). Considerou-se dislipidemia a existência de alteração em pelo menos um dos exames. As análises estatísticas foram realizadas a partir do Epi Info 3.3 e Stata 7.0. RESULTADOS: A prevalência de sobrepeso foi de 14,4% enquanto que 83,9% dos estudantes eram eutróficos e 1,7% apresentavam baixo peso. Não foram encontradas diferenças estatisticamente significantes para o estado nutricional quando estratificado por sexo e tipo de escola. Todas as taxas bioquímicas investigadas mostraram algum nível de alteração. Chamou à atenção a prevalência de dislipidemia, observada em 66,7% dos estudantes, e a alteração do HDL-colesterol, verificada em 56,7% destes. Registrou-se associação estatisticamente significante (p<0,05) do Índice de Massa Corporal, categorizado em tercis, com o colesterol total e sua fração LDL, inclusive quando estratificados por sexo e tipo de escola. CONCLUSÕES: Considerando-se a faixa etária estudada, foram elevados os achados de sobrepeso e dislipidemia. Recomenda-se a adição de medidas preventivas, a fim de evitar que cada vez mais crianças e adolescentes venham a se tornar adultos portadores de obesidades e outras doenças crônicas.

Abstract
RATIONALE In adults, obstructive sleep apnea (OSA) is associated with metabolic dysfunction that improves with treatment of OSA. No equivalent studies exist in children. OBJECTIVE To examine the relationship between metabolic markers and OSA with time and treatment in children. METHODS Metabolic markers measured on a fasting morning blood sample at diagnostic polysomnography and follow-up 1.3 +/- 0.6 yr later. MEASUREMENTS AND MAIN RESULTS Forty-five children (34 males), aged 6.9 +/- 3.5 yr, and including 12 obese subjects, were in the final analysis. There were no differences in metabolic markers between children with and without OSA at initial study; however, obese children had significantly higher insulin (106.1 +/- 72.1 vs. 66.7 +/- 37.6 pmol/L; p = 0.028), insulin/glucose ratio (23.7 +/- 14.3 vs. 14.7 +/- 8.0; p = 0.02), and significantly lower high-density lipoprotein cholesterol (1.3 +/- 0.2 vs. 1.6 +/- 0.4 nmol/L; p = 0.005) than nonobese children. Twenty children underwent surgical removal of adenotonsillar tissue, whereas 12 children with OSA elected not to have treatment. OSA persisted after treatment in five children, and resolved in 27. Thirteen children did not have OSA on initial or follow-up studies. At follow-up, there was a small but significant improvement in total cholesterol in those children whose OSA was resolved (4.8 +/- 0.8 to 4.7 +/- 0.6 nmol/L; p = 0.005) and a trend for obese children with persisting OSA to have elevated insulin levels compared with obese children without OSA (p = 0.07). CONCLUSION Obesity appears to be the major influence on metabolic dysfunction in children with OSA, but these preliminary data also suggest that resolution or persistence of OSA may affect changes in metabolic function over time.

Abstract
OBJECTIVES Our goal was to report the prevalence of elevated blood pressure and lipid levels among eighth-grade adolescents from 3 US locations and differences by gender, ethnicity, and overweight percentile group. METHODS Fasting blood samples and blood pressure levels were obtained from 1717 eighth-grade students from 12 predominantly minority schools in 3 states (Texas, California, and North Carolina) during spring 2003. Age, gender, ethnicity, weight, and height were ascertained and BMI calculated. The presence of abnormal total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and triglycerides, prehypertension, hypertension, at risk for overweight, and overweight were calculated and compared with the findings of previous youth studies. We examined whether prevalence differed by gender, ethnicity, or BMI group. RESULTS A total of 23.9% of participants had high blood pressure, 16.7% had borderline total cholesterol, 4.0% had high total cholesterol, 10.5% had borderline low-density lipoprotein cholesterol, 3.9% had high low-density lipoprotein cholesterol, 13.3% had low high-density lipoprotein cholesterol, and 17.2% had high triglycerides. A total of 19.8% of participants were at risk of overweight (BMI > or = 85th percentile, < 95th percentile) and 29% were overweight (BMI > or = 95th percentile). The prevalence of risk factors was associated (P < .05) with the overweight group and differed by age and gender. CONCLUSIONS Prevalence of elevated blood pressure was higher in this sample than in previous national surveys in which subjects were less overweight. Associations between overweight and both elevated lipid and blood pressure levels suggest that adolescents overweight or at risk for overweight should be screened for elevated blood pressure and lipid levels.

Abstract
BACKGROUND The aim of the current study was to examine the interrelationship between certain cardiovascular disease (CVD) risk factors and overweight, as well as to provide some indication on the prevalence of underweight, overweight and obesity in primary schoolchildren in urban Turkey. METHODS 1044 randomly selected children aged 12 and 13 years old from the urban areas of Istanbul, Ankara and Izmir were examined. The main variables of interest were fatness determined by body mass index and sum of skinfolds, lipid profile, dietary intake, physical fitness and habitual physical activity. RESULTS Both overweight boys and girls were found to have lower cardiovascular fitness levels compared to their normal weight peers. Overweight boys reported lower energy and macronutrient intake than their normal weight counterparts. Regarding biochemical indices, overweight boys were found to have higher total cholesterol (TC), Low Density Lipoprotein-cholesterol (LDL-C), triglycerides (TG) and LDL-C/HDL-C ratio compared to normal weight boys, while overweight girls were found to have lower High Density Lipoprotein-cholesterol (HDL-C) and higher TG compared to their normal weight peers. Finally, the prevalence of underweight, overweight and obesity for the overall population was found to be 12%, 12% and 2%, respectively. CONCLUSIONS The study revealed that overweight and obesity in children coexisted with more unfavorable lipid profiles and lower cardiovascular fitness levels. This finding points out the emergent need for suitable measures to be implemented in order to identify and counteract these health and social problems early in life.

Abstract
The epidemic of childhood overweight continues to grow at staggering rates, increasing nearly four-fold between 1963 and 2000. Children that are overweight are more apt to be overweight adults and are more likely to suffer adverse health consequences associated with excess weight. Nurses have a unique presence in the healthcare environment to assess children for overweight, provide parent/child nutritional education, and conduct obesity-related research. This article provides an overview of the current body of literature surrounding the definition and measurement of overweight and the morbidity association with childhood overweight.

Abstract
Hypertension, as in adults, is a frequent complication found in children with chronic kidney disease (CKD). Indeed, hypertension has now become one of the most prevalent chronic diseases of childhood. The most recent data available (2003) indicate that at least 38% of children with CKD in the United States are receiving antihypertensive therapy. Only recently has it been shown in children that hypertension, traditionally considered a marker for disease severity in children, is additionally a significant and independent risk factor for accelerated deterioration of kidney function and progression of CKD and a significant risk factor for cardiovascular disease. The following review outlines the differences and similarities of childhood versus adult hypertension with respect to measurement, diagnosis, treatment, and consequence in CKD. The definition of hypertension changes continually as a child grows with or without CKD. Despite numerous guidelines, the diagnosis of childhood hypertension continues to be based on epidemiologic data rather than evidence. For children, the current definition includes 2 categories: high normal, which is blood pressure (BP) between the 90th and 95th percentile, and hypertensive, which is BP above the 95th percentile. The evaluation of all hypertensive children should include a complete assessment of end-organ damage, including eyes, cardiovascular system (including blood vessels), kidneys, and nervous system. For children with CKD and end-stage renal disease (ESRD), a high percentage have left ventricular hypertrophy (LVH). The finding of end-organ damage or comorbidity (CKD, diabetes) in any child is an absolute indication for immediate pharmacologic therapy, whereas the presence of hypertension above the 95th percentile in children without CKD warrants initial intervention such as life style modification. The guidelines for measurement of BP in children with CKD are similar to those in children without CKD and include casual BP measurement, self-measured BP, and ambulatory BP monitoring. The recommendation for BP measurement in children is, when permitted, by auscultative method with a well-calibrated mercury manometer. Most casual BP measurements are performed with an automated oscillometric device whose validation has not been confirmed in children with CKD. The ambulatory BP monitor (ABPM) has 2 advantages: it significantly correlates with the presence of end-organ damage, and it identifies abnormal BP patterns that are frequently present in CKD patients, such as hypertension during the sleep period. An abnormal ABPM pattern can also be predictive of the development of end-organ damage. Treatment of hypertension in children, with and without CKD, is based on 3 factors: degree of BP elevation, the presence of cardiovascular risk factors, and the presence of end-organ damage. Additionally, the initial antihypertensive agent may be selected on available and age-appropriate formulations (eg, suspension and dosage selection). A physician treating a hypertensive child with CKD faces multiple challenges. They include selecting the convenience of available automated devices and the ABPM versus traditional auscultatory techniques upon which all normative standards have been based. Current research initiatives propose to develop pharmacokinetic and pharmacodynamics properties of antihypertensive medications and to study the effect of early intervention on end-organ damage.
