Association of physical activity with body mass index, waist circumference and incidence of obesity in older adults
2018
Background There is limited, and inconsistent, data on the prospective association between physical activity and surrogate markers of adiposity in older adults. We aim to determine the prospective association of leisure time physical activity (LTPA) with body mass index (BMI), waist circumference (WC) and the incidence of obesity. Methods This prospective analysis included 7144 individuals with a mean age of 67 ± 6.2 years, from the PREvencion con DIeta MEDiterranea (PREDIMED) study. BMI and WC were measured and LTPA was recorded using the Minnesota Leisure Time Physical Activity Questionnaire. Exposure and outcome variables were calculated as cumulative average of repeated measurements. Re…
Profiling children longitudinally: A three-year follow-up study of perceived and actual motor competence and physical fitness.
2020
Longitudinal designs enhance our understanding of children's development and its influence on movement behaviors and health. This three-year follow-up study aimed to develop profiles according to perceived and actual motor competence (MC) (locomotion, object control, and overall) and physical fitness in boys and girls longitudinally including children's temporal migrations among clusters in terms of profiling trends. A secondary aim was to compare physical activity participation and weight status at each time point according to these profiles. One hundred and four typically developing Spanish children (45.8% girls) between 4 and 9 years old at baseline participated in this study. Data were …
Accuracy of different cutoffs of the waist‐to‐height ratio as a screening tool for cardiometabolic risk in children and adolescents: A systematic rev…
2021
The present systematic review with meta-analysis sought to estimate the accuracy of different waist-to-height ratio (WHtR) cutoff ranges as risk indicators for cardiometabolic health in different populations of children and adolescents. Systematic searches were undertaken to identify studies in apparently healthy participants aged 3–18 years that conducted receiver operating characteristic curve analysis and reported area under the receiver operating characteristic curves for WHtR with any cardiometabolic biomarker. Forty-one cross-sectional studies were included in the meta-analysis, including 138,561 young individuals (50% girls). Higher area under summary receiver operating characteristi…
Effects of Chitosan on Plasma Lipids and Lipoproteins
2014
Chitosan can favorably modulate plasma lipids, but the available data are not conclusive. We evaluated the effect of chitosan on plasma lipids and lipoproteins in 28 patients with plasma triglyceride levels >150 mg/dL (mean age: 63 ± 12 years), not taking other lipid-lowering agents. All patients received a chitosan derived from fungal mycelium (Xantonet, Bromatech, Italy) at a fixed dose of 125 mg/d in addition to their current medications for 4 months. Polyacrylamide gel electrophoresis was used to measure low-density lipoprotein (LDL) subclasses. After treatment, total cholesterol reduced by 8%, LDL cholesterol by 2%, and triglycerides by 19%, with a concomitant 14% increase in high-…
Sport disciplines, types of sports, and waist circumference in young adulthood – a population-based twin study
2017
Purpose: The benefits of physical activity (PA) in preventing abdominal obesity are well recognized, but the role of different sport disciplines remains open. We aimed, therefore, to investigate how participation in different sport disciplines, and the number and types of sports engaged in are associated with waist circumference (WC) in young adulthood. Methods: This population-based cohort study comprised 4027 Finnish twin individuals (1874 men), with a mean age of 34 y (32-37), who answered a survey, including self-measured WC. We extracted the number and identified the types (aerobic, power, and mixed) of the different sport disciplines respondents reported participating in. Results: The…
Nitric oxide production is increased in severely obese children and related to markers of oxidative stress and inflammation
2011
Nitric oxide (NO) is the major endothelium-derived relaxing factor. The aim of the present study was to evaluate NO synthesis and metabolism in severely obese children with different degrees of metabolic risk and to ascertain their relation with the parameters of oxidative stress and inflammation.The study involved 60 obese children evaluated with respect to metabolic risk factors (MRFs) (324 MRFs and 28 ≥ 4 MRFs) and 50 normal weight children between 7 and 14 years of age. Nutritional status was assessed by clinical and anthropometric examination. MRFs (serum lipid profile, insulin resistance indexes, blood pressure) in addition to uric acid, homocysteine, leptin, and inflammatory markers …
Serum ionized magnesium levels in relation to metabolic syndrome in type 2 diabetic patients
2006
Objective: To evaluate circulating serum ionized magnesium (i-Mg) concentrations in patients with type 2 diabetes mellitus, and to investigate its relationship with the components of the metabolic syndrome. Design: cross-sectional study. Setting: Outpatients' service for diabetic patients at the University Hospital of Messina, Italy. Subjects: 290 patients with type 2 diabetes mellitus. Measures of Outcome: Serum i-Mg was measured by ion selective electrode. Age, gender, body mass index (BMI), waist circumference, blood pressure, fasting glucose, HbA1c, HDL cholesterol, triglycerides, and urinary albumin excretion rate (UAER) were considered in the analyses. Patients with hypomagnesemia, de…
Cross-sectional associations of objectively-measured sleep characteristics with obesity and type 2 diabetes in the PREDIMED-Plus trial.
2018
Study Objectives: To examine independent and combined associations of sleep duration and sleep variability with body composition, obesity and type 2 diabetes (T2D) in elders at high cardiovascular risk. Methods: Cross-sectional analysis of 1986 community-dwelling elders with overweight/obesity and metabolic syndrome from PREDIMEDPlus trial. Associations of accelerometry-derived sleep duration and sleep variability with body mass index (BMI), waist circumference (WC) and body composition were assessed fitting multivariable-adjusted linear regression models. Prevalence ratios (PR) and 95% confidence intervals (CI) for obesity and T2D were obtained using multivariable-adjusted Cox regression w…
Eight-year-old children with high cardiorespiratory fitness have lower overall and abdominal fatness.
2008
1) To examine whether cardiorespiratory fitness (CRF) is associated with waist circumference (WC) and overall and abdominal fatness in eight-year-old girls and boys. 2) To determine whether children with high CRF have lower WC, overall and abdominal fatness within the same body mass index (BMI) category compared with those with low CRF.A cross-sectional study of 304 eight-year-old children in Tampere, Finland whose parents responded to a postal invitation and participated in measurements.Total body fat percentage (BF%), abdominal region fat percentage (AF%), and fat-free mass (FFM) were assessed by dual-energy X-ray absorptiometry (DXA). WC, height and weight were measured. International BM…
Associations between body mass index, waist circumference and erectile dysfunction: a systematic review and META-analysis
2020
Growing evidence reports that obesity might play a role in erectile dysfunction (ED), but limited knowledge is available. We conducted a meta-analysis to estimate the prevalence of ED in overweight men and men with obesity. We performed a systematic review up to 01/04/2019 to investigate the associations between obesity and ED. Applying a random-effect model, we calculated the prevalence of ED, the odds ratio (OR) for the presence of ED by Body Mass Index (BMI) categories and the mean differences between ED and controls in BMI and Waist Circumference (WC). Among 3409 studies, we included 45 articles with 42,489 men (mean age = 55 years). Taking normal weight men as reference, the prevalence…
