Filter by:1. To test whether chronic intermittent cold exposure is more effective in programmed body weight loss when compared to conventional programmed weight loss. 2. To measure the metabolic responses (e.g. in the white and brown adipose tissue, muscle and circulating markers) of treatment with chronic intermittent cold exposure and conventional treatment 3. To measure tissue specific changes of weight loss and the treatment with chronic intermittent cold exposure in glucose uptake rate in adipose organ (white and brown adipose tissue), liver, myocardium, skeletal muscle and brain 4. To measure tissue specific biochemical indicators before and after treatment with chronic intermittent cold exposure from white adipose tissue and skeletal muscle. 5. To compare changes in body composition and fat distribution after weight loss using chronic cold exposure or using conventional method
The global epidemic of obesity in childhood continues to evolve and threaten future health and life expectancy primarily due to the increased incidence of cardiovascular disease. Obesity is strongly related to high blood pressure (hypertension) and both conditions pose a risk for target organ damage, which can follow a subject from childhood into adult life. The AORTA study will investigate central hemodynamics and organ damage in 100 obese children and adolescents in order to gain insight to the complex interplay of hypertension, obesity and subclinical damage in order to intensify more precise prevention, thereby reducing the future development of cardiovascular disease.
This project will evaluate an Internet delivery strategy to address weight loss and maintenance among rural midlife and older women.
The study investigated the effectiveness and cost-effectiveness of a cognitive and behavioral weight management program, complemented by an interactive Web site and brief telephone coaching, implemented among TRICARE non-active-duty beneficiaries. A total of 1,755 participants from four Midwestern states were randomized to one of three randomized controlled trial groups with increasing intervention intensity: mailed material and basic Web access (RCT1), plus an interactive Web site (RCT2), plus brief phone- and Web-based coaching support from health lifestyle coaches (RCT3). The study assessed changes in participants' weight, blood pressure, diet, and physical activity from baseline to 6, 12, and 15 to 18 months. Analyses estimated overall cost savings and calculated the cost-effectiveness ratio of each randomized controlled trial compared with a "do-nothing" alternative as the cost per quality-adjusted life year.
This study will evaluate the potential beneficial cardiometabolic effect of moderate (5%) weight loss and progressive (5%, 10%, and 15%) weight loss in obese adults without diabetes. Participants will be randomly assigned to one of 2 groups. Group 1: supervised weight loss group (low-calorie diet). Group 2: supervised weight maintenance group (normal diet). Of those assigned to group 1, half of the participants will lose 5% of their body weight and the other half will lose 5%, 10%, and 15% of their weight over time under the guidance of a dietitian. Research testing will be repeated at each time point (5%, 10%, and 15% weight loss). In group 2, research testing will be repeated after six months.
The main objectives of this study are to collect pilot data to assess feasibility (accrual, retention, compliance), to estimate the variability of outcome measures, and to obtain preliminary estimates of treatment efficacy based on group differences in body composition (decreases in ectopic fat stores while maintaining lean mass), cardio-metabolic risk factors including glucoregulatory function (glucose, insulin), inflammation (C-reactive protein, IL-6), blood pressure and lipids (HDL, LDL, TC, TG), and measures of physical function and muscle strength. While this is just a pilot study, randomization will be used so that the investigators can obtain a realistic estimate of accrual (which is often less in a randomized trial) and an unbiased estimate of treatment efficacy. The investigators will accomplish these objectives by conducting a 2-arm, 3-month randomized, clinical trial in 24 older (60-79), abdominally obese (BMI ≥30 kg/m2 and waist circumference ≥ 102 cm and ≥ 88 cm in men and women, respectively) men and women. Participants will be randomized to a soy-based or animal-based, 3-month, hypocaloric dietary intervention to achieve our specific aims: Primary Aim: To determine our ability to recruit and retain older, obese adults to a 3 month soy-based meal replacement weight loss intervention and assess the study participant's ability to adhere to the intervention protocol (weight, compliance logs, serum isoflavones). Secondary Aims: 1. To estimate the variability of and obtain preliminary estimates of the effect of the soy-based meal replacement on measures of body composition, including abdominal (total, subcutaneous and visceral fat), liver, and pericardial fat; anthropometrics (body weight, waist/hip circumference); and whole body fat and lean mass. 2. To estimate the variability of and obtain preliminary estimates of the effect of the soy-based meal replacement on biomarkers of cardiometabolic risk including glucoregulatory function (glucose, insulin), inflammation (C-reactive protein, IL-6), blood pressure and lipids (HDL, LDL, TC, TG). 3. To estimate the variability of and obtain preliminary estimates of the effect of the soy-based meal replacement on physical function (short physical performance battery, 400-m walk) and muscle strength (grip and knee extensor strength) and size (CT thigh muscle). 4. To document any adverse events associated with the soy-based meal replacement.
The overall objective of this pilot project is to test in 50 women with a history of gestational diabetes mellitus (GDM), the effectiveness and feasibility of an 8 month intensive lifestyle intervention to reduce the rate of metabolic abnormalities within 1 year after delivery.
The purpose of this pilot study is to demonstrate the anatomical modulation of subcutaneous fat across the waist and hips that occurs through application of the Erchonia® ML Scanner (MLS) Laser manufactured for non-invasive body contouring of the waist and hips.
Military personnel face many physiological challenges, including sustained physical activity and prolonged periods of negative energy balance. Chronic energy deficiency often results in a loss of skeletal muscle mass and can reduce overall bone health. Recent evidence suggests that dietary interventions that provide protein in excess of the current national dietary recommendation may confer protection against the negative effects of energy deficiency on the musculoskeletal system. The primary objective of this randomized, controlled study is to assess the effects dietary protein intake spanning the current acceptable macronutrient distribution range on musculoskeletal health following prolonged energy deficiency. Findings from this investigation will improve current understanding of dietary conditions necessary to reduce the damaging effects of caloric deficiency on musculoskeletal health in warfighters. Furthermore, given the rise in obesity in military populations, findings may aid in the development of nutritional weight management strategies that promote healthy weight loss without compromising musculoskeletal health.
A whole of school intervention with daily physical activity and healthy food for students with intellectual disabilities. The aim is to provide plenty of concrete examples of healthy life style choices and using school personnel and peers as role models. This will presumably result in healthier weight, better fitness and not least in new familiar healthy habits.
