Active clinical trials for "Overweight"

The goal of this study is to test the feasibility and utilization of a redesigned mobile app and health coaching platform (Vira) in youth (aged 18-25 years) with elevated depressive symptoms who are overweight/obese and/or self-report parental history of overweight/obesity. Eligible participants will be randomly assigned to one of two groups: one group will use the Vira mobile app intervention with support from a health coach, and the other group will use the Vira mobile app intervention without coaching. Both groups will use the app for 12 weeks.

This trial compares two treatment methods: Orlistat 60 mg to be taken three times daily one capsule; indicated for weight loss in overweight adults. Important is also that it is taken along with a reduced-calorie and low-fat diet. Polyglucosamine tablets to be taken two times daily two tablets, taken with the two main meals with the highest fat content, indicated for weight maintenance and weight loss.

The study will use a comprehensive behavioral intervention adapted for pregnant women to change dietary intake, eating behavior and physical activity. The central hypothesis of this study is that the intervention will reduce excess gestational weight gain and achieve clinical and metabolic benefits in obese and overweight pregnant women and their infants over the first year of life.

The purpose of this study is to examine the impact of a lifestyle intervention on gestational weight gain, postpartum weight loss, and other secondary outcomes relative to a usual care control group.

Previous studies suggest self-regulatory techniques including self-monitoring, and SMS text-messaging as an intervention modality, can modify health behaviors including physical activity (PA). The primary purpose of this study was to examine change in objectively measured PA in a randomized controlled pilot trial that tested a wearable sensor/device (Fitbit One) for self-monitoring and SMS text-messaging prompts to promote PA in overweight/obese adults. In a 2-group design, 67 participants were provided the Fitbit One and half were randomized to receive 3 daily SMS-based PA prompts. A Fitbit One was provided to facilitate self-monitoring with a wearable tracker for instant feedback and website of daily PA summaries. Outcome measures were number of steps and minutes of PA by intensity-level using two accelerometers: Actigraph GT3X+ (primary) at baseline and 6-week follow-up and Fitbit One (secondary) at baseline and weeks 1-6. The main hypothesis was that text messaging plus the Fitbit One would show a greater increase in steps and minutes of PA compared to only the Fitbit One at 6-week follow-up.

The purpose of this study is to investigate whether stimulating physical activity during the first year of life influences growth and body composition, and stimulates motor activity and motor development

The purpose of this study is to design and assess the impact of an electronic alert and tool set to assist with physician identification and counseling of overweight patients.

The aim is to investigate the development of overweight and obesity from infancy to school age, and to evaluate an intervention to prevent further development of overweight and obesity among children. A follow-up study will be conducted on 267 children and will allow comparison between children that developed overweight with the ones who did not. Subjects will be requited at 10 years of age from a previous project. These children have been studied when they were 6-18 months old and a follow-up was conducted at 4 years of age. Sixteen percent of the children were overweight at 4 years of age and retrospective data of e.g. food intake, blood lipids and anthropometric measurements exists. In the present follow-up data regarding food and physical activity habits, anthropometric measurements and blood samples of e.g. blood lipids, IGF1 will be collected. An intervention study will be conducted on 80-120 overweight children that will be randomized into one intervention and one control group. An intervention during two years will encourage long term healthy habits regarding diet and physical activity through group meetings and supervision. Information about food habits will be collected through questionnaires, interviews and diaries. Measurement of physical activity and energy expenditure will be made with Sense Wear and double labeled water, and will be used to validate reported food intake. Further, anthropometric measurements and blood samples will be collected.

The purpose of this research is to increase community awareness about the relationship between physical activity, screen time, and nutrition and how these factors influence healthy weight management. The problem of obesity is at epidemic proportions and has become the most important public health problem confronting the United States today. Of greatest concern is the 300% increase in obesity rates among children and youth over the past twenty years. Childhood obesity is a precursor of adult obesity.

Dietary fructose potently exacerbates the dyslipidemia associated with obesity, insulin resistance and accelerated atherosclerosis. In a randomized crossover outpatient study of 15 overweight adults, we will measure the increase over 4 hours in serum VLDL triglyceride palmitate made by the liver from each single oral dose of fructose (0.5 g/kg), fructose:glucose 1:1 (1 g/kg) or fructose:glucose 1:1 (2 g/kg). Our hypotheses are that the synthesis of palmitate from dietary fructose will be 1) greater when consumed with glucose and 2) show a dose-response. The lipogenic responses will be compared and correlated with markers of carbohydrate and lipid flux measured after fasting and post-fructose. The results will serve as a guide to the development of a new outpatient probe of the de novo lipogenic pathway in subjects who vary in their lipogenic response to oral fructose. These studies should ultimately yield valuable new information about the mechanisms linking dietary carbohydrate to elevated triglycerides, diabetes and cardiovascular disease.
