UNLABELLED The rapid rising prevalence of childhood obesity is related to increased risk of obesity-related diseases during adulthood. The aim of the present study was to review the data concerning the prevalence of metabolic syndrome (MS) in European children and adolescents (Part 1) and to determine and compare the prevalence of MS among overweight and(More)
Genetic variability in the FADS1-FADS2 gene cluster [encoding delta-5 (D5D) and delta-6 (D6D) desaturases] has been associated with plasma long-chain PUFA (LCPUFA) and lipid levels in adults. To better understand these relationships, we further characterized the association between FADS1-FADS2 genetic variability and D5D and D6D activities in adolescents.(More)
OBJECTIVE Apolipoprotein A5 (APOA5) gene variants have been shown to be associated with elevated TG levels; the T-1131C (rs662799) variant has been reported to confer risk for the metabolic syndrome in adult populations. Little is known about the APOA5 variants in pediatric population, no such information is available for pediatric obesity at all. Here we(More)
OBJECTIVE Recently, the association of the natural variants rs1260326 and rs780094 of the glucokinase regulatory protein (GCKR) gene with increased fasting triglycerides and decreased fasting plasma glucose in diabetic adults was reported; the minor alleles were also found to reduce the risk of type 2 diabetes. The present study examined the possible(More)
OBJECTIVE Genetic variability in the NR1H3 gene (encoding LXRα) and in several of its target genes is associated with serum HDL-cholesterol (HDL-C) concentrations. We sought to assess if these associations could be detected in adolescents. METHODS Thirty-nine polymorphisms in NR1H3, ABCA1, APOE, CETP, PLTP and LPL were analysed in the HELENA study (n =(More)
CD36 is a membrane receptor with a wide variety of functions, including the regulation of energy metabolism, fat storage, and adipocyte differentiation. To assess the relationship between CD36 gene single-nucleotide polymorphisms (SNPs) and obesity in adolescents, we evaluated the relationship between CD36 SNPs and the risk of obesity in a case-control(More)
OBJECTIVE The peroxisome proliferator-activated receptor-gamma2 (PPARG2) Pro12Ala polymorphism has been associated with a higher BMI and a lower risk of type 2 diabetes in adulthood. The association between adiposity and PPARG variants can be influenced by environmental factors such as early growth, dietary fat, and (as recently shown) breast-feeding. The(More)
OBJECTIVE Gln223 Arg polymorphism of the leptin receptor (LEPR) gene is one of the most frequently examined polymorphisms of this gene and has been suggested to be associated with energy expenditure (EE). The aim of the present study was to investigate the association of this variant on indicators of EE-resting metabolic rate (RMR), postabsorptive and(More)
OBJECTIVE To examine whether physical activity attenuates the effect of the FTO rs9939609 polymorphism on body fat estimates in adolescents. DESIGN Cross-sectional study. SETTING Athens, Greece; Dortmund, Germany; Ghent, Belgium; Heraklion, Greece; Lille, France; Pécs, Hungary; Rome, Italy; Stockholm, Sweden; Vienna, Austria; and Zaragoza, Spain, from(More)
INTRODUCTION Metabolic syndrome affects 15-30 percentage of the population. It is characterized by obesity, hypertension, diabetes mellitus, insulin resistance, hypercholesterolemia and hypertriglyceridemia. AIMS In a recent study metabolic syndrome was shown to be transmitted on maternal lineage in a large family; an uridine to cytidine transition was(More)
