Abstract
Abstract
Objective Lipid abnormalities during childhood might be associated with a higher risk of atherosclerosis development in adulthood. In Ethiopia, there were no data on this area. The present work was aimed at assessing the lipid profile abnormalities among children and adolescents aged between 5 and 17 years, in Addis Ababa, Ethiopia.
Materials and Methods The present school-based cross-sectional study was done from March 2019 to October 2019 in the capital city, Addis Ababa. A total of 504 students were randomly recruited for this study. The total cholesterol, triglyceride, low-density lipoprotein, and high-density lipoprotein-cholesterol levels were determined using the Cobas c501 automated chemistry analyzer. The prevalence of lipid abnormalities was described in percentages. Bivariate and multivariate analyses were performed, and data with p-value less than 0.05 was considered statistically significant.
Results Dyslipidemia in at least one of the lipid profiles was observed in 322 (63.9%) school children, whereas only one of the participants had an abnormality in all four lipid profile tests. The prevalence of total cholesterol 200 mg/dL or higher, low-density lipoprotein 130 mg/dL or higher, high-density lipoprotein less than 40 mg/dL, and triglycerides 130 mg/dL or higher was in 14 (2.8%), 16 (3.2%), 294 (58.4%), and 46 (19.1%) participants, respectively.
Conclusion In the current work, the majority of the study participants had a normal lipid profile except increased prevalence of a reduced concentration of high-density lipoprotein-cholesterol. The overall prevalence of serum lipid abnormalities was 63.9%. Serum lipid levels did not show significant differences with sex, age, fasting habits, or obesity.

Front Physiol 2022; 13:1098408. [PMID: 36685213 PMCID: PMC9852907 DOI: 10.3389/fphys.2022.1098408] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Accepted: 12/19/2022] [Indexed: 01/07/2023] Open
Abstract
Introduction: Rodent models of cardiovascular disease have uncovered various types of lymphatic vessel dysfunction that occur in association with atherosclerosis, type II diabetes and obesity. Previously, we presented in vivo evidence for impaired lymphatic drainage in apolipoprotein E null (ApoE -/- ) mice fed a high fat diet (HFD). Whether this impairment relates to the dysfunction of collecting lymphatics remains an open question. The ApoE -/- mouse is a well-established model of cardiovascular disease, in which a diet rich in fat and cholesterol on an ApoE deficient background accelerates the development of hypercholesteremia, atherosclerotic plaques and inflammation of the skin and other tissues. Here, we investigated various aspects of lymphatic function using ex vivo tests of collecting lymphatic vessels from ApoE +/+ or ApoE -/- mice fed a HFD. Methods: Popliteal collectors were excised from either strain and studied under defined conditions in which we could quantify changes in lymphatic contractile strength, lymph pump output, secondary valve function, and collecting vessel permeability. Results: Our results show that all these aspects of lymphatic vessel function are altered in deleterious ways in this model of hypercholesterolemia. Discussion: These findings extend previous in vivo observations suggesting significant dysfunction of lymphatic endothelial cells and smooth muscle cells from collecting vessels in association with a HFD on an ApoE-deficient background. An implication of our study is that collecting vessel dysfunction in this context may negatively impact the removal of cholesterol by the lymphatic system from the skin and the arterial wall and thereby exacerbate the progression and/or severity of atherosclerosis and associated inflammation.

Proteomics and metabolomics analyses reveal the full spectrum of inflammatory and lipid metabolic abnormalities in dyslipidemia. Biomed Chromatogr 2021; 35:e5183.

Abstract
Dyslipidemia is a common, chronic metabolic disease associated with cardiovascular complications. Due to the multiplicity of etiological factors, the pathogenesis of dyslipidemia is still unclear. In this study, we combined proteomics and metabolomics methods to analyze the plasma of patients with dyslipidemia and healthy subjects. isobaric tags for relative and absolute quantification (iTRAQ) markers, combined with LC-MS/MS proteomics technology and the UHPLC/Orbitfast-X Tribrid system, were used to establish the metabolite profile in clinical dyslipidemia. A total of 137 differentially expressed proteins, mainly related to biological processes such as protein activation cascades, adaptive immune responses, complement activation, acute inflammatory responses, and regulation of acute inflammatory responses, were identified. These proteins are involved in the regulation of important metabolic pathways, such as immunity and inflammation, coagulation and hemostasis, lipid metabolism, and oxidation and antioxidant defenses. The analysis of clinical metabolites showed there were 69 different metabolites in plasma, mainly related to glycerolipid, sphingolipid, porphyrin, α-linolenic acid, linoleic acid, and arachidonic acid metabolism, suggesting that the regulation of inflammation and lipid metabolism may be disturbed in patients with dyslipidemia. Among these, significant changes were observed in indole-3-propionic acid (IPA), which is considered as a potential biomarker of dyslipidemia. The combined analysis of proteins and metabolites showed that arachidonic acid, linoleic acid, and lipid metabolic pathways were closely related to dyslipidemia. IPA may be a potential biomarker. The information provided in this study may provide new insights into the pathogenesis of animal models of dyslipidemia and related disease models, as well as potential intervention targets.

Abstract
The lymphatic system has many functions, including macromolecules transport, fat absorption, regulation and modulation of adaptive immune responses, clearance of inflammatory cytokines, and cholesterol metabolism. Thus, it is evident that lymphatic function can play a key role in the regulation of a wide array of biologic phenomenon, and that physiologic changes that alter lymphatic function may have profound pathologic effects. Recent studies have shown that obesity can markedly impair lymphatic function. Obesity-induced pathologic changes in the lymphatic system result, at least in part, from the accumulation of inflammatory cells around lymphatic vessel leading to impaired lymphatic collecting vessel pumping capacity, leaky initial and collecting lymphatics, alterations in lymphatic endothelial cell (LEC) gene expression, and degradation of junctional proteins. These changes are important since impaired lymphatic function in obesity may contribute to the pathology of obesity in other organ systems in a feed-forward manner by increasing low-grade tissue inflammation and the accumulation of inflammatory cytokines. More importantly, recent studies have suggested that interventions that inhibit inflammatory responses, either pharmacologically or by lifestyle modifications such as aerobic exercise and weight loss, improve lymphatic function and metabolic parameters in obese mice. The purpose of this review is to summarize the pathologic effects of obesity on the lymphatic system, the cellular mechanisms that regulate these responses, the effects of impaired lymphatic function on metabolic syndrome in obesity, and the interventions that may improve lymphatic function in obesity.

Abstract
OBJECTIVE To identify determinants for the development of "normal weight metabolically unhealthy" (NWMU) profiles among previously metabolically healthy normal weight children. METHODS The QUALITY cohort comprises youth 8-10 years of age with a parental history of obesity (n = 630). Of these, normal weight children with no metabolic risk factors were identified and followed up 2 years later (n = 193). Children were classified as NWMU if they remained normal weight but developed at least one cardiometabolic risk factor. They were classified as normal weight metabolically healthy otherwise. Multivariable logistic regression models were used to identify whether adiposity (anthropometrics and DXA), lifestyle habits (physical activity, screen time, vegetables, and fruit- and sugar-sweetened beverages intake), fitness, and family history of cardiometabolic disease were associated with new onset NWMU. RESULTS Of the 193 normal weight and metabolically healthy children at baseline, 45 (23%) became NWMU 2 years later (i.e., 48% had elevated HDL cholesterol, 13% had elevated triglycerides, and 4% had impaired fasting glucose). Changes in adiposity between baseline and follow-up were associated with an increased risk of NWMU for all adiposity measures examined (e.g., for ∆zBMI OR = 3.95; 95% CI: 1.76, 8.83). Similarly, a 2-year change in screen time was associated with incident NWMU status (OR = 1.24; 95% CI 1.04, 1.49). CONCLUSIONS Children who increase their adiposity levels as they enter puberty, despite remaining normal weight, are at risk of developing cardiometabolic risk factors. Studies examining long-term consequences of NWMU profiles in pediatrics are needed to determine whether changes in screening practice are warranted.

ACTA ACUST UNITED AC 2019; 55:medicina55070392. [PMID: 31330902 PMCID: PMC6681190 DOI: 10.3390/medicina55070392] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2019] [Revised: 07/11/2019] [Accepted: 07/18/2019] [Indexed: 02/06/2023]
Abstract
Background and Objectives: Dyslipidaemia and its associated complications have been reported to increase mortality among type 2 diabetes mellitus (T2DM) patients. However, there is a dearth of data on the incidence of dyslipidemia among Ghanaian patients with T2DM. This study evaluated dyslipidemia among newly diagnosed T2DM patients at Dormaa Presbyterian Hospital, Ghana. Materials and Methods: This cross-sectional study recruited a total of 215 participants at the Presbyterian Hospital, Dormaa-Ghana. A well-structured questionnaire was administered to collect demographic data. Predisposing factors of dyslipidemia such as BMI, hypertension, and family history of diabetes were also obtained. Lipid profile was performed on the serum obtained from each respondent. Dyslipidaemia was defined as total cholesterol (TC) >200 mg/dL, triglyceride (TG) >150 mg/dL, low density lipoprotein cholesterol (LDL-c) >100 mg/dL, and high-density lipoprotein cholesterol (HDL-c) <40 in males and <50 mg/dL in females. Combinations of the individual parameters of dyslipidaemia were further evaluated. Results: Of the total (215) participants, 86 (40%) were males and 129 (60%) were females, representing a ratio of 1:1.5. High total cholesterol was more prevalent in females (69.0%) than males (53.5%). Generally, dyslipidaemia was predominant among those aged >40 years, with the exception of increased LDL-c (25.1%), which was higher among the 20–40 years age group. The male participants exhibited significantly (p < 0.001) higher percentages of all combined measures of dyslipidaemia—such as high TG and reduced HDL-c (77.9%), high TG and elevated LDL-c (75.6%) and high LDL and low HDL (65.1%). BMI was significantly associated with HDL levels (p = 0.02), whereas family history of diabetes was associated with TC (p = 0.004) and TG levels (p = 0.019). Conclusion: Combined dyslipidaemia is relatively high among newly diagnosed T2DM patients in Ghana, and in those >40 years. Gender is significantly associated with combined dyslipidaemia in T2DM, and males may be at a higher risk than females. BMI and family history of diabetes are potential risk factors of dyslipidaemia in T2DM.

Abstract
AIM to elucidate predictors of high level of basal triglycerides (TG) in blood of children of persons with early (onset: men ≤55, women ≤60 years) ischemic heart disease (EIHD). MATERIALS AND METHODS We examined 316 families: patients (probands) (n=295; 77.9 % after MI) with EIHD, their spouses (n=219; 83.1 % women) and native children of probands (n=413; 55.7 % men) aged 5-38 years. In children aged 5-17 and 18-38 years proband's spouse was mother in 88 and 77 % of cases, respectively. Hypertriglyceridemia in children (HTG) was defined in persons aged 5-17 years as ≥90 percentile (Lipid Research Clinics), ≥18 years - ≥1.7 mmol / l or HTG drug treatment. Predictors of HTG were selected by binary logistical regression with adjustment for age, sex and drugs. RESULTS HTG was found in 31 / 158 children aged 5-17 years. Its independent predictors were systolic arterial pressure (odds ratio [OR] of top [>108] vs. two bottom [≤108 mm Hg] tertiles 3.85, 95 % confidence interval [CI] 1.38-10.7, р=0.010), heart rate (HR, OR of top [>78] vs. two bottom [≤78 bpm] tertiles 2.94, 95 % CI 1.20-7.23, р=0.019), and high density lipoprotein cholesterol (HDL-C, OR 0.35, 95 % CI 0.13-0.94; р=0.038) of their children; HR (OR of top [>72] vs. two bottom [≤72 bpm] tertiles 3.56, 95 % CI 1.38-9.11, р=0.008), low density lipoprotein cholesterol (OR 2.49, 95 % CI 1.12-5.52, p=0.025]), and type 2 diabetes (OR 25.9, 95 % CI 1.01-665.3; p=0.049) of the parent - proband's consort. HTG was found in 35 / 255 children aged 18-38 years and was associated with own age (OR 1.10, 95 % CI 1.02-1.19, р=0.012) and male sex (OR 6.21, 95 % CI 2.45-15.8; р=0.000). HTG was independently associated with body mass index (OR top [>25.4] vs. two bottom [≤25.4 kg / m2] tertiles 4.94, 95 % CI 2.13-11.4, р=0.000); basal glycemia (OR top [5.1] vs. two bottom [≤5.1 mmol / l] tertiles 2.52, 95 % CI 1.17-5.43, р=0.019); HDL-C (OR 0.17, CI 0.04-0.81, 0.027); alcohol consumption (OR consuming more than once vs. once a week and less 2.27, 95 % CI 1.02-5.02, p=0.044) of these children; HDL-C (OR 0.19, 95 CI 0.04-0.94; p=0.041) of the proband-parent. CONCLUSIONS HTG in children aged 5-38 years with parental early IHD was independently associated mainly with own characteristics, forming components of metabolic syndrome. Attention should be paid to the dominance of maternal transmission in children and adolescents (age group 5-17 years).

Abstract
METHODS The incidence of obesity is increasing worldwide, especially in countries with accelerated economic growth. We determined the prevalence of and associations between overweight/obesity and cardiovascular risk factors in pre-pubertal (seven- to 11-year-old) schoolchildren (both genders, n = 198) in Luanda, Angola. Biochemical (fasting blood) and clinical examinations were obtained in a single visit. Data are reported as prevalence (95% confidence intervals) and association (r, Pearson). RESULTS Prevalence of overweight/obesity was 17.7% (12.4- 23.0%), high blood pressure (BP > 90% percentile) was 14.6% (9.7-19.5%), elevated glucose level was 16.7% (11.5-21.9%) and total cholesterol level > 170 mg/dl (4.4 mmol/l) was 69.2% (62.8-75.6%). Significant associations between body mass index (BMI) and systolic and diastolic BP (r = 0.46 and 0.40, respectively; p < 0.05) were found. No association between BMI and elevated glucose or cholesterol levels was found. CONCLUSION The prevalence of cardiovascular risk factors was high in pre-pubertal schoolchildren in Angola and fat accumulation was directly associated with blood pressure increase but not with other cardiovascular risk factors.

Abstract
Childhood overweight and obesity are worldwide public health problems and risk factors for chronic diseases. The presence of SNP in several genes has been associated with the presence of obesity. A total of 580 children (8-13 years old) from Queretaro, Mexico, participated in this cross-sectional study, which evaluated the associations of rs9939609 (fat mass obesity-associated (FTO)), rs17782313 (melanocortin 4 receptor (MC4R)) and rs6548238 (transmembrane protein 18 (TMEM18)) SNP with obesity and metabolic risk factors. Overweight and obesity prevalence was 19·8 and 19·1 %, respectively. FTO, MC4R and TMEM18 risk allele frequency was 17, 9·8 and 89·5 %, respectively. A significant association between FTO homozygous and MC4R heterozygous risk alleles and obesity was found (OR 3·9; 95 % CI 1·46, 10·22, and OR 2·1; 95 % CI 1·22, 3·71; respectively). The FTO heterozygous subjects showed higher systolic and diastolic blood pressures, compared with the homozygous for the ancestral allele subjects. These results remain significant after considering adiposity as a covariate. The FTO and MC4R genotypes were not significantly associated with total cholesterol, HDL-cholesterol and insulin concentration. No association was found between TMEM18 risk allele and obesity and/or metabolic alterations. Our results show that, in addition to a higher BMI, there is also an association of the risk genotype with blood pressure in the presence of the FTO risk genotype. The possible presence of a risk genotype in obese children must be considered to offer a more comprehensive therapeutic approach in order to delay and/or prevent the development of chronic diseases.

Prediction of Preadolescent Overweight and Poor Cardiometabolic Outcome in Children up to 6 Years of Age: Research Protocol. JMIR Res Protoc 2016; 5:e85. [PMID: 27339755 PMCID: PMC4937175 DOI: 10.2196/resprot.5158] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2015] [Revised: 01/22/2016] [Accepted: 01/22/2016] [Indexed: 12/27/2022] Open
Abstract
Background Dynamic risk estimations may enable targeting primary prevention of overweight and overweight-related adverse cardiometabolic outcome in later life, potentially serving as a valuable addition to universal primary prevention. This approach seems particularly promising in young children, as body mass index (BMI) changes at a young age are highly predictive of these outcomes, and parental lifestyle interventions at a young age are associated with improved long-term outcome. Objective This paper describes the design of our study, which aims to develop digitized tools that can be implemented in the Dutch Child Health Care (CHC) system or by pediatricians for children up to 6 years of age. These tools will enable (1) dynamically predicting the development of overweight, hypertension or prehypertension, low high-density lipoprotein cholesterol (HDL-C) values, and high total cholesterol to HDL-C ratio by early adolescence and (2) identifying children who are likely to have poor cardiometabolic outcome by the age of 5-6 years and by the age of 10 years. Methods Data will be obtained from the Generation R (n=7893) and Prevention and Incidence of Asthma and Mite Allergy (PIAMA; n=3963) cohorts, two Dutch prenatally recruited cohorts. We will select candidate predictors that can be assessed during the first visit and/or during subsequent visits to the CHC center or pediatrician, including sex; parental age, education level, and BMI; smoking exposure; ethnicity; birth weight; gestational age; breastfeeding versus formula feeding; and growth data through the age of 6 years. We will design dynamic prediction models that can be updated with new information obtained during subsequent CHC visits, allowing each measurement to be added to the model. Performance of the model will be assessed in terms of discrimination and calibration. Finally, the model will be validated both internally and externally using the combined cohort data and then converted into a computer-assisted tool called ProCOR (Prediction Of Child CardiOmetabolic Risk). Results This is an ongoing research project financed by the Dutch government. The first results are expected in 2016. Conclusions This study may contribute to the national implementation of digitized tools for assessing the risk of overweight and related cardiometabolic outcome in young children, enabling targeted primary prevention, ultimately yielding relevant health gains and improved resource allocation.

Abstract
OBJECTIVE To evaluate the association of hypomagnesemia with prehypertension (preHTN) and hypertension in children. STUDY DESIGN A total of 3954 apparently healthy Mexican children were enrolled in a cross-sectional study. Exclusion criteria were type 2 diabetes; hepatic, renal, or endocrine disease; impaired fasting glucose; chronic diarrhea; and intake of vitamins or magnesium supplements in the previous 6 months. preHTN was defined by systolic and/or diastolic blood pressure ≥90th to <95th percentile and hypertension by systolic and/or diastolic blood pressure ≥95th percentile, according to age, sex, and height percentile. Hypomagnesemia was defined by serum magnesium concentration <1.8 mg/dL (<0.74 mmol/L). To control for potential sources of bias related to age, participants were allocated into 2 groups, aged 6-10 years and 11-15 years. RESULTS The prevalence of preHTN and hypertension was 12.2% and 6.4%, respectively, in children aged 6-10 years and 13.9% and 10.6% in those aged 11-15 years. Hypomagnesemia was identified in 59 children with preHTN (27.3%) and 52 (45.6%) with hypertension in the 6-10 year age group, and in 115 children with preHTN (36.0%) and 109 (49.6%) with hypertension in the 11-15 year age group. Adjusted multiple logistic regression analysis showed that in children in both age groups, hypomagnesemia was associated with both preHTN (6-10 years: OR, 2.18, P < .0005; 11-15 years: OR, 1.38, P = .018) and hypertension (6-10 years: OR, 4.87, P < .0005; 11-15 years: OR, 1.83, P = .0002). CONCLUSION Our results indicate that serum magnesium level <1.8 mg/dL is significantly associated with preHTN and hypertension in apparently healthy children.

Abstract
The prevalence of childhood obesity has reached alarming rates world-wide. The aetiology seems to be an interplay between genetic and environmental factors, and a surrogate measure of this complex interaction is suggested as familial predisposition. Familial predisposition to obesity and related cardiovascular disease (CVD) complications constitute the presence of obesity and/or obesity-related complications in primarily blood-related family members. The approaches of its measurement and applicability vary, and the evidence especially of its influence on obesity and obesity treatment in childhood is limited. Studies have linked a familial predisposition of obesity, CVD (hypertension, dyslipidaemia and thromboembolic events), and type 2 diabetes mellitus to BMI as well as other adiposity measures in children, suggesting degrees of familial aggregation of metabolic derangements. A pattern of predispositions arising from mothers, parents or grandparents as being most influential have been found, but further comprehensive studies are needed in order to specify the exact implications of familial predisposition. In the scope of childhood obesity this article reviews the current literature regarding familial predisposition to obesity and obesity-related complications, and how these familial predispositions may impact obesity in the offspring.

Abstract
BACKGROUND The dyslipidemia associated with excess weight is a risk for cardiovascular disease. Worldwide and in South Africa adolescent obesity has been reported. OBJECTIVES To determine the association between dyslipidemia and anthropometric indices in black and white adolescents. METHODS The study involved 129 black and 69 white adolescents aged 12 to 16 years. Data collected included height, weight, waist circumference (WC) and skinfolds, blood pressure and blood for glucose, insulin, total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), triglycerides (Trig) and C - reactive protein (CRP). RESULTS WC correlated negatively with HDL in both blacks (p=0.042) and whites (p=0.008) and in whites it correlated positively with LDL (p=0.006); TC/HDL (p=<0.001) and LDL/HDL ratio (p<0.0001). WC/Hgt correlated negatively with HDL (p=0.028) and positively with LDL/HDL (p=0.026 and p<0.0001) in both races. In whites positive correlations were between WC/Hgt and TC (p=0.049); LDL (p=0.003) and TC/HDL (p<0.0001). BAZ correlated positively with TC/HDL ratio (p=0.004) and LDL/HDL ratio (p=0.002). The most common abnormalities were HDL and LDL. CONCLUSION Whites exhibited more associations between dyslipidemia and anthropometric indicators as compared to Blacks, suggesting that there might be differences in the lipid metabolism or even susceptibility to risk factors in adolescents.

Abstract
Non-obese children with elevated serum insulin levels and metabolic disorders such as, hyperglycemia, hypertension, and/or hypertriglyceridemia are a subset of children in high risk of developing cardiovascular disease later in life. Since usually the health policies for the prevention of the obesity associated disorders in children are based on the screening focused on the obese, frequently the metabolically obese normal-weight (MONW) children are not identified in primary care setting. Given that characterization of the MONW children is an important public health issue, and that a large amount of resources might be unnecessarily used in the screening of metabolic risk of nonobese children; we review data regarding criteria for the early recognition of this subset of children in high risk of developing cardiovascular disease. Results of our review suggests that the presence of family history of type 2 diabetes and/or hypertension, the elevated percentage of body fat, and the high birth-weight should be taken into account as criteria of high cardiovascular risk, irrespective of obesity.

Abstract
OBJECTIVE To determine whether the association between family history of diabetes (FHD) and impaired fasting glucose (IFG) is independent of body mass index (BMI) in children and adolescents. METHODS In all 443 (11.9%) children and adolescents with FHD, and 3280 (88.1%) without FHD were enrolled in a population-based cross-sectional study. Eligible subjects to participate were apparently healthy children and adolescents aged 7-15 yr from Middle and Northern Mexico. Obesity was defined by age- and gender-specific BMI >or= 95th percentile. FHD was defined as positive if at least one first degree relative had diabetes. The IFG was defined by fasting plasma glucose >or= 100 mg/dL and < 126 mg/dL. RESULTS IFG was identified in 390 (88.0%) and 62 (1.9%) children and adolescents with and without FHD, respectively. In the group with positive FHD, IFG was diagnosed in 146 (37.4%), 79 (20.2%), and 165 (42.3%) children and adolescents who were obese, overweight, and normal-weight, respectively. On the other hand, in the group without FHD, IFG was identified in 21 (33.9%), 14 (22.6%), and 27 (43.5%) children and adolescents who were obese, overweight, and normal-weight, respectively. In the overall population, the age-, sex-, and BMI-adjusted logistic regression analysis showed a strong and independent association between FHD and IFG [odds ratio (OR) -11.7; 95% CI 9.5-21.2]. This association remained strong for girls and boys in a subsequent analysis stratified for BMI category. CONCLUSIONS The presence of FHD in a first degree relative is associated with IFG, even in the absence of obesity.

Abstract
BACKGROUND To determine the relationship between family history of hypertension (FHH) and cardiovascular risk factors (CVRF) in healthy prepubertal children. METHODS DESIGN Cross-sectional, population-based study. SETTING Elementary schools from San Luis Potosi and Durango, cities in middle and northern Mexico. PARTICIPANTS A total of 358 randomly enrolled, healthy boys and girls aged 6-10 years in Tanner stage 1, with and without FHH. OUTCOME MEASURES Odds ratio (OR) that estimates the relationship between FHH and CVRF. RESULTS FHH was identified in 72 (20.1%) children; 212 (59.2%) children had at least one CVRF, where low high-density lipoprotein (HDL)-cholesterol (36.3%), elevated waist circumference (WC) (29.3%), and hypertriglyceridemia (28.8%) were the most frequent; high-blood pressure (HBP) and hyperglycemia were recognized in 10 (3.3%) and 1 (0.3%) children. Metabolic syndrome and hyperinsulinemia were identified in 36 (10.0%) and 48 (13.4%) children. In all subjects, hyperinsulinemia (OR 2.0; 95% confidence interval (CI) 1.2-8.4), but not other CVRF was significantly associated with FHH. Subsequent analysis stratified by WC showed that FHH was not associated with CVRF in children with elevated WC. Among children with nonelevated WC, FHH in the maternal branch, but not in the paternal branch, was associated with hyperinsulinemia (OR 1.5; 95% CI 1.1-5.5), HBP (OR 4.0; 95% CI 1.3-30.1), hypertriglyceridemia (OR 1.6; 95% CI 1.1-7.2), and low HDL-cholesterol (OR 1.3; 95% CI 1.1-3.0). CONCLUSION Results show that FHH in the maternal branch is associated with CVRF in children with nonelevated WC.

Abstract
AIM Since the mortality rate due to cardiovascular disease continues to increase, research into dyslipidemia has been emphasized in not only adults but also paediatric populations. We aimed to study the risk factors of dyslipidemia in Chinese children. METHODS Nine hundred and sixty-two children, aged 6-18 years, in Beijing were enrolled. For each child, data were collected on body height (cm), body weight (kg), sitting height (cm), waist circumference, upper arm circumference, serum lipid levels, as well as familial history of dyslipidemia and early onset cardiovascular disease. Subgroups were determined on the basis of age and sex. RESULTS The prevalence rate of dyslipidemia was 11.1% (107/962). Children with dyslipidemia differed significantly from those without, in sitting height, upper arm circumference, body mass index (BMI), waist-to-height ratio (WHR) and diastolic and systolic blood pressure (p < 0.05). Logistic regression analysis suggested that WHR, diastolic blood pressure and positive familial history were risk factors for dyslipidemia in children. CONCLUSION Sitting height, upper arm circumference, BMI, WHR, diastolic pressure and systolic pressure were significantly higher in dyslipidemic children than in normal subjects in China. BMI, WHR, diastolic pressure and familial history of dyslipidemia and early-onset cardiovascular disease were risk factors for dyslipidemia in Chinese children.

Abstract
BACKGROUND Epidemiological data on impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) based on a representative Mexican sample are not available; thus, the objectives of this study were to determine the prevalence and distribution of IFG and IGT, and to establish its relationship with obesity in Mexican adults. METHODS We performed a cross-sectional population-based study on a representative sample of Mexican adults aged 30 to 65 years. Anthropometric measurements of obesity that included waist circumference (WC) and total body fat percentage were collected and the body mass index calculated. All subjects also underwent an oral glucose tolerance test. Diagnosis of glucose metabolism disorders was based on criteria of the American Diabetes Association. RESULTS Prevalence of IFG, IGT, and IFG+IGT was 24.6%, 8.3%, and 10.3%, respectively. The age-adjusted prevalence of IFG (49.5% and 50.5%), IGT (49.1% and 50.9%), and IFG+IGT (57.3% and 42.7%) was similar in men and women. Prevalence of obesity was 45.9% with predominance in women (48.8% versus 42.1%, P = 0.01). A total of 394 (31.0%) individuals were overweight. Among the 550 prediabetic normal weight subjects, 70 (22.4%), 15 (14.2%), and 7 (5.3%) had IFG, IGT, or IFG+IGT. The odds ratio (OR) between WC and IFG (OR 3.1, CI(95%) 1.4-9.7), IGT (OR 3.2, CI(95%) 1.2-9.1), and IFG+IGT (OR 2.8, CI(95%) 1.3-8.2) was higher than the OR of other measurements of obesity. CONCLUSIONS Prevalence of prediabetes in the Mexican adult population is high. WC is the measure of obesity more strongly associated with metabolic glucose disorders. A high proportion of subjects with normal weight exhibit prediabetes.

Abstract
Elevated low-density lipoprotein cholesterol (LDL-C) level in childhood is an increasing problem, mainly due to a rising prevalence secondary to the childhood obesity epidemic and better recognition and screening. Vascular changes and impaired endothelial function associated with elevated LDL-C are apparent even in early childhood. Secondary adiposity-related cases are at higher risk due to the clustering of risk factors besides overweight, such as the atherogenic lipid triad, change in the atherogenic properties of the LDL-C particle itself, and the presence of insulin resistance. Prevention should focus on maintaining a healthy lifestyle, including a restricted fat and cholesterol diet, encouraging physical activity, and decreasing sedentary pursuits to maintain an appropriate weight in children. For children and adolescents found to have elevated LDL-C, management should focus on the pursuit of a healthy lifestyle mirroring that for prevention for at least 6 months. Additional dietary therapy, such as plant stanol and sterol esters, have also been shown to modestly reduce LDL-C levels. If the adoption of a healthy lifestyle is not sufficient to reduce LDL-C, lipid-lowering drugs should be considered in selected patients. Current drugs of choice are statins and potentially ezetimibe. Long-term treatment with statins has been shown to markedly reduce carotid intima-media thickness in children and adolescents, particularly when started early. Current evidence supports early and efficient treatment for affected children.
