Filter by:Overweight and obesity have become an increasing problem in patients on hemodialysis. However, in virtually all observational studies in chronic kidney disease(CKD) and dialysis patients , using body mass index(BMI) as metric fat mass is associated inversely with death rate. Nevertheless, it is questionable that obesity can be considered an unequivocal protective factor in chronic diseases as increase body fat mass appears to be a potential cause of the chronic inflammation frequently present in these patients. The consequences of this inflammation are impaired nutritional status, accelerated atherosclerosis, and increased mortality. In the present study, by using dual-energy X-ray absorptiometry (DEXA) and bioimpedance spectroscopy (BIS) to evaluated the contributions of fat mass to outcomes in an observational cohort of hemodialysis patients. Besides, we aim to assess the relationship between body fat composition, clinical metabolic risk profiles, measures of adiposity, such as waist circumference (WC), visceral adiposity index, waist-to-hip ratio (WHR), and waist-to-height ratio (WHtR), markers of inflammation and adipocytokines in these maintenance hemodialysis patients.
Background and aims: The purpose of this study was to evaluate the effect of high intensity interval training (HIIT) on body composition, physical fitness, metabolic fitness and muscle histology in men with overweight or obesity compared to continuous aerobic training (CAT). Material and methods: 16 male participants with overweight/obesity (age range: 42 - 57 years, body mass index: 28 - 36 kg/m²) were randomized to HITT (n=8) or CAT (n=8). HIIT was composed of two sprint blocks of 10 minutes at ventilatory threshold (VT), within between a continuous block of 10 minutes, twice a week for 15 weeks. CAT was composed of three blocks of 10 minutes continuous endurance training at VT. After 5 weeks, intensity was increased to 110% of VT. Changes in body composition, physical fitness (peakVO2 and anaerobic threshold (AT)), basal respiratory exchange ratio (bRER) and insulin sensitivity by oral glucose tolerance test were evaluated. Mitochondrial content was evaluated by transmission electron microscopy (TEM) in muscle biopsies.
The objectives of this clinical study are to determine the tolerance of dietary supplement Valedia (blend of plant extracts) through the evaluation of several parameters : - Various blood biological parameters for tolerance (preprandial): blood glucose, insulin, fructosamine, total cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol, oxidized LDL, us-CRP, creatinine, ASAT, ALAT, gGT, phosphatase alcaline, bilirubine, urea. - Urinary parameters: urea, creatinine. - Hemodynamic parameters: heart rate and blood pressure. - Cardiac function: ECG. - Weight.
The purpose of this study is to develop, implement, and evaluate a behavioral weight management intervention with a communication training component for Mexican-American women. The study has three specific aims. Aim 1: Develop a behavioral weight loss intervention that modifies evidence-based behavioral weight loss treatment using results from formative data collected from Mexican-American mother-daughter dyads. The adapted intervention will focus on improving dyadic communication and collaboration for providing reciprocal support for healthy eating and physical activity behaviors. Aim 2: Implement and evaluate a pilot weight management program adapted for mother-daughter dyads. Dyads will be randomly assigned to partner-based treatment with or without communication skills training. Aim 3: Evaluate associations between changes in weight, weight-related behaviors, and psychosocial variables with changes in measures assessing interpersonal communication.
The investigators propose to 1) assess the feasibility, acceptability and preliminary efficacy of a gender- and culturally-sensitive weight loss intervention in 48 overweight/obese Hispanic males ages 18-64 over 12 weeks; 2) assess participant characteristics and process measures related to the uptake of mobile-health (mHealth) technology in overweight/obese Hispanic males over 12 weeks; and 3) assess pathologic changes in the liver in Hispanic men enrolled in a 12-week weight loss intervention using a non-invasive MRI as a therapeutic response biomarker.
World Health Organization (WHO) defined body mass index (BMI) as the ratio of weight in kilograms to the square of the height in meters (kg/m2). BMI has been used widely to diagnose obesity as it is a simple method to be carried out and is also inexpensive. According to WHO, there were 1.9 billion overweight individuals in 2014 with the age of 18 years old or above. Of 1.9 billion overweight individuals, there were 600 million obese adults. The prevalence of cardiovascular disease is higher among the overweight and obese individuals compared to individuals with normal body mass index. This probably is due to altered cardiovascular autonomic regulation. The risk of getting cardiovascular diseases is also higher among physically inactive individuals. As much as 60% of American adults are not regularly active and 25% of them are not active at all. Obese and overweight individuals tend to be physically inactive and it has been shown that there is a negative relationship between BMI and heart rate recovery (HRR). HRR is defined as difference in heart rate between maximum exercise and 1 minute later during recovery period after stopping of exercise. HRR after exercise stress is due to withdrawal of sympathetic nervous system and the reactivation of parasympathetic nervous system. Parasympathetic nervous system is altered in obese individuals therefore leading to poor HRR after exercise. Aerobic training not only can reduce the body composition but also improves the autonomic cardiovascular control. There is limited literature support for any study which shows that potential of 4 weeks aerobic training can influence the heart rate recovery in sedentary healthy adults. Most of studies conducted were using minimum of 6 to 8 weeks of aerobic training. The potential of 4 weeks of aerobic training in improving the autonomic nervous system among sedentary adults is still unclear. Therefore, we hypothesized in our study that there will be effect of 4 weeks of aerobic training on vagal modulation.
Effects of foods or food substances on energy expenditure are of particular interest, because of the increasing prevalence of obesity and its consequent metabolic diseases like type II diabetes and fatty liver disease, all risk factors for the development of cardiovascular diseases (CVDs). Recently, the Goji berry (Lycium Barbarum, wolfberry) was introduced into the Western diet. L. Barbarum originates from Asia, where it is used to improve the health of several organs. Although L. Barbarum is promoted as a super food with many beneficial effects, consistent scientific evidence for these effects is lacking. In one study, it was found that short-term intake of L. Barbarum polysaccharides - equal to 150 g of fresh berries - increased postprandial oxygen consumption. This indicates that L. Barbarum might exert beneficial effects on energy expenditure. Furthermore, long-term intervention trials have shown beneficial effects of L. Barbarum on lipid and glucose metabolism in mice and type II diabetic patients and on inflammatory status in healthy elderly. Altogether, L. Barbarum has the potential to be used as a functional food to increase metabolic health, but detailed information on the postprandial effects of L. Barbarum is missing. We therefore propose this double-blinded, randomized, placebo controlled intervention trial to investigate the effect of a single dose of L. Barbarum on postprandial energy expenditure substrate oxidation, metabolic flexibility, lipid and glucose metabolism and inflammatory markers.
Introduction Overweight and obesity are characterised by excess fat, which results in weight gain and is identified by the Body Mass Index (BMI). Studies show that overweight and obesity are the result of a complex interaction between genetic and environmental factors, which begins prenatally. Various studies have shown that physical exercise is an important component of weight loss programmes and that it also benefits the metabolic profile. Other authors have reported that greater weight loss is achieved by a programme that includes both diet and exercise, rather than either of these alone. Aim The aim of this study is to analyse an intervention based on play as a means of improving the body composition of children with overweight or obesity. Design / Method The design of the Kids-Play study is based on cases and controls. The study was conducted in Granada (Spain) The analysis sample of 98 children was divided into two groups: cases, consisting of 49 children, who participated in an intervention programme based on physical activity, play and nutritional advice (to both the child and the parents); and controls, another 49 children, who received only nutritional advice.
The present study is designed to examine the effect of changes in body weight and related parameters associated with a commercially-available, low-carbohydrate diet plan. A parameter proposed to be studied here is the impact of fructose restriction and weight loss on serum uric acid concentrations and arterial stiffness.
The purpose of this study is to test in overweight and inactive adults whether the new PAI eHealh APP leads to better adherence to a physical activity regimen than the wearable step counter App from the market leader FitBit, and to evaluate if improved adherence will be reflected in a better cardiovascular profile in this group.
