The surprising influence of family history to type 2 diabetes on anaerobic performance of young male élite athletes

2014

Aims/Hypothesis It is known that family history to type 2 diabetes induces anthropometric changes in various populations. Regular physical activity can induce adaptations in these subjects regularizing body composition and anthropometric parameters. The aim of this study is therefore to understand if family history to type 2 diabetes affects anaerobic performance in young male élite athletes. Methods Forty six young male élite athletes were tested. Thirty three without family history to type 2 diabetes (FH-) and thirteen with family history to type 2 diabetes (FH+). Anthropometric parameters, body composition, physiological parameters and athletic performance were assessed. Results Weight (…

P2‐289: PREVALENCE AND CORRELATES OF SUBJECTIVE MEMORY IMPAIRMENT IN A RURAL ITALIAN POPULATION OF SUBJECTS AGED 50 YEARS AND OVER: DATA FROM THE ZAB…

2014

Background: Neuropathology related to dementia slowly accumulates over decades. Consequently, identifying persons at a higher risk of dementia could postpone or prevent dementia by timely targeting modifiable risk factors. In this light, mild cognitive impairment (MCI) has been identified as the transitional stage between normal aging and dementia. So far, the understanding of MCI in thegeneral population remains limited. Therefore,we investigated determinants, MRI-correlates, and prognosis of MCI within the populationbasedRotterdamStudy.Methods:A total of 4198 participants were included in this study. Firstly, we studied age, APOE4 carriership, waist circumference, hypertension, diabetes m…

Distribution of Intraocular Pressure and Its Association with Ocular Features and Cardiovascular Risk Factors

2013

Purpose To describe the distribution of intraocular pressure (IOP) and its association with ocular features and cardiovascular risk factors in an adult European cohort. Design Population-based, cross-sectional study. Participants This analysis was based on a Gutenberg Health Study (GHS) cohort that included 4335 eligible enrollees from among 5000 subjects who participated in the survey from 2007 through 2008. The age range was 35 to 74 years at enrollment. Methods Participants underwent a standardized protocol with a comprehensive questionnaire; ophthalmic examination including slit-lamp biomicroscopy, noncontact tonometry, fundus photography, central corneal thickness measurement, and visu…

Aerobic Fitness Does Not Modify the Effect of FTO Variation on Body Composition Traits

2012

Purpose Poor physical fitness and obesity are risk factors for all cause morbidity and mortality. We aimed to clarify whether common genetic variants of key energy intake determinants in leptin (LEP), leptin receptor (LEPR), and fat mass and obesity-associated (FTO) are associated with aerobic and neuromuscular performance, and whether aerobic fitness can alter the effect of these genotypes on body composition. Methods 846 healthy Finnish males of Caucasian origin were genotyped for FTO (rs8050136), LEP (rs7799039) and LEPR (rs8179183 and rs1137101) single nucleotide polymorphisms (SNPs), and studied for associations with maximal oxygen consumption, body fat percent, serum leptin levels, wa…

Serum leptin is associated with serum uric acid concentrations in humans.

1999

This cross-sectional study aimed to evaluate the relationship between leptin and the cluster of abnormalities often referred to as the metabolic syndrome. The serum leptin concentration, body mass index (BMI), percent body fat, total fat mass (FM), waist and hip circumference, waist to hip ratio (WHR), prevalence of hypertension, and triglyceride (TG), lipoprotein, and uric acid concentration were determined in 86 type 2 diabetic (n = 59) and healthy (n = 27) subjects. Multiple regression analyses showed that the estimates of total body obesity (BMI, percent body fat, and total FM), sex, and serum uric acid concentration are independently associated with the serum leptin concentration. The …

The relationship between adipokines and the onset of type 2 diabetes in middle-aged men: The PRIME study

2016

Abstract Aims Epidemiological evidence suggests that adipokines may be associated with the onset of type 2 diabetes, but the evidence to date is limited and inconclusive. This study examined the association between adiponectin and leptin and the subsequent diagnosis of type 2 diabetes in a UK population based cohort of non-diabetic middle-aged men. Methods Baseline serum levels of leptin and adiponectin were measured in 1839 non-diabetic men aged 50–60 years who were participating in the prospective population-based PRIME study. Over a mean follow-up of 14.7 years, new cases of type 2 diabetes were determined from self-reported clinical information with subsequent validation by general prac…

Are body mass index, waist circumference and waist-to-hip ratio associated with leptin in 90-year-old people?

2013

Data on how body mass index (BMI), waist circumference (WC) and waist-to-hip ratio (WHR) are associated with body fat in the oldest-old people are scarce. The purpose of this study was to examine if BMI, WC or WHR are associated with leptin, a biological surrogate measure of body fat in 90-year-old people. The data comes from the Vitality 90+ Study, a prospective population-based study of people living in Tampere, Finland. BMI, WC, WHR and plasma concentration of leptin were available for 160 women and 54 men aged 90 years. BMI and WC had a strong significant positive association with leptin both in women and in men, but WHR was associated with leptin only in men. In conclusion, based on th…

Metabolic syndrome and severity of fibrosis in nonalcoholic fatty liver disease: An age-dependent risk profiling study

2017

Background & Aims: Metabolic syndrome (MS) and its individual components are associated with the severity and progression of nonalcoholic fatty liver disease (NAFLD). We sought to evaluate the relationship between MS components and the risk of severe hepatic fibrosis in NAFLD patients discriminated by age. Methods: We considered 863 consecutive patients with biopsy-proven NAFLD, who had been fully evaluated for components of MS. Results: Multivariate logistic regression analysis showed that F3-F4 was associated with visceral obesity, IFG/diabetes, and low high-density lipoprotein (HDL) cholesterol, but not triglycerides >150 or arterial hypertension. A significant interaction was found betw…

Time course of insulin resistance during antiviral therapy in non-diabetic, non-cirrhotic patients with genotype 1 HCV infection

2009

Background Genotype 1 (G1) hepatitis C virus (HCV) is associated with insulin resistance (IR) and its clearance seems to improve insulin sensitivity. We aimed to evaluate the time course of IR in response to antiviral therapy in non-diabetic, non-cirrhotic G1 HCV patients and to assess the effect of metabolic factors on sustained virological response (SVR). Methods A total of 83 consecutive treatment-naive G1 chronic hepatitis C (CHC) patients were evaluated by anthropometric and metabolic measurements, including IR using the homeostasis model assessment (HOMA). Patients were considered to have IR if HOMA was >2.7. All cases had a liver biopsy scored for staging, grading and steatosis. A…
