Active clinical trials for "Obesity"

Regular exercise is a cornerstone in the prevention and the management of cardio-metabolic risk factors. Some of the beneficial effect of exercise training occurs through metabolic flexibility' enhancement. Metabolic flexibility is the ability to respond or adapt to conditional changes in metabolic demand, and previous literature has shown that individuals living with obesity have an impaired metabolic flexibility compared to lean individuals. However, there is a lack of empirical evidence on the impact of sprint interval training on metabolic flexibility and whether this translates into clinically meaningful outcomes. This study will evaluate the impact of 4-week sprint interval training in normal weight individuals as well as individuals living with obesity on acute and chronic metabolic flexibility, irisin secretion and insulin sensitivity.

The ToyBox proposal addresses Knowledge-Based Bio-Economy (KBBE)-2009-2-1-03 - Behavioural models for prevention of obesity, with a particular focus on children. It will primary aim to influence children's behaviours and prevent obesity in early childhood. The proposal will identify key behaviours related to early childhood obesity and their determinants and evaluate behavioural models and educational strategies. Based on the obtained insights at a local level, a multidisciplinary team will develop and implement a school based family involved intervention programme that could be applied on a European scale. Process, impact, outcome and cost-effectiveness evaluation will be conducted to support decision making for European Public Health Policy. The combined use of Precede-Proceed Model and Intervention Mapping will provide the framework for the development, implementation and evaluation of the ToyBox intervention. To achieve this, the project will be subdivided into 10 Work Packages (WPs). This carefully planned stepwise approach will include systematic reviews, secondary analyses of existing data sets, focus group research and school policies overview. The ToyBox project consortium spans the necessary multidisciplinary variety of experts such as public health experts, epidemiologists, nutritionists, physical activity experts, pedagogists, psychologists, behavioural scientists, nutritionists, paediatricians, early childhood psychologists, health economists, totalling 15 partners, from 10 countries. The consortium, consists of 11 universities, 1 research institute, 2 advocacy groups and a small to medium enterprise (SME) representing all regions of Europe. The consortium has ample experience in conducting and coordinating multi-centre international research as well as undertaking dissemination activities to all relevant stakeholders.

The purpose of the study is to pilot-phase test the effectiveness of the microclinic social induction model and its effects on behavioral and metabolic outcomes in different levels of social and familial relationships in Qatar. The investigators novel microclinic model is based on the principle that both healthy and unhealthy behaviors spread through preexisting social networks. A microclinic is a small group of approximately 2-8 friends or family members who are taught to modify their own behaviors as well as the behaviors of those around them, with a particular focus on the four "M's": Meals, Movement, Monitoring, and Medication. More than social support groups or peer-to-peer interventions, the microclinic model is unique in its focus on the long-term propagation of healthy behaviors throughout a participant's entire social network. Qatar is uniquely positioned (with its central geographic location in the Gulf region and its leadership in science and education) to spearhead a regional intervention focused on managing and preventing diabetes in the Gulf region.

The investigators long term-goal is to help YMCA programs across the nation successfully acheive the Y of USA "Healthy Eating and Physical Activity Standards". Our objective here is threefold. First, the investigators will work with South Carolina YMCA leadership to achieve the "Healthy Eating and Physical Activity Standards" and implement our HEPA Strategies in YMCA programs across the state, evaluate the uptake of and adherence to the standards and strategies, and identify factors that influence their implementation. Second, the investigators will evaluate the impact of acheiving the standards on children's MVPA and the serving and consumption of FV and water during the programs. Third, the investigators will evaluate the costs associated with and the cost-effectiveness of meeting the standards in terms of improvements in activity and healthy eating.

The objectives are to test the acute effects of different extruded pulse snacks on: 1) aerobic endurance and substrate oxidation during exercise 2) response of blood glucose, insulin and appetite on an aerobic exercise session, and 3) food intake two hours following the exercise session. The investigators hypothesize that consumption of food products containing pulse ingredients 60 minutes before exercise will increase aerobic endurance (lower oxygen consumption), decrease carbohydrate oxidation (greater respiratory quotient), and a reduction in lactate production during compared to the same exercise session following the ingestion of a non-pulse food. The investigators also hypothesize that consumption of extruded pulse snacks will lead to lower blood glucose, insulin, appetite and food intake, suggesting lower calorie compensation, following a 60-minute aerobic exercise session compared to the same exercise session following the ingestion of a non-pulse food.

This is a pilot study examining the effect of dietary supplements that contain soy products. The purpose of this study to find out if soy supplementation can help to reduce the storage of a certain kind of fat on the body, visceral fat. Visceral fat is fat found deep in the abdomen; it has the potential to increase the risk of certain health problems.

Adolescents nowadays is having most of their times other than school hours spending on screen by playing games, watching the movies and surfing the internet. Thus, it was suggested that Internet-based interventions have the potential for establishing healthy dietary style and physical activity that may persist in adulthood and reduce the risk of chronic disease. Preventing adolescent obesity requires an attitude of willingness by adolescents to implement healthy behaviors. By providing the health related activities in website, it would help the adolescents to spend time on screen by having something which can benefit them and improve their knowledge and attitudes.

The purpose of this social media group randomized trial (GRT) is to test the feasibility of our Baby Dayr for Teen Moms intervention to increase maternal responsiveness to infant cues and implement healthy feeding practices through development of a healthy feeding style. Aim 1: Evaluate the feasibility and acceptability of the Baby Dayr intervention administered to the target population as it relates to their acceptance and satisfaction with the content, format, delivery, and use of social media. Aim 2: Explore efficacy of the Baby Dayr intervention administered to adolescent mothers of infants 4 months of age or less as assessed by maternal responsiveness, feeding style, and feeding practices evaluated at the completion of the intervention using self-report methods.

The purpose of this study is to find out whether a technology-base healthy lifestyle program is an acceptable and effective way for African-American mothers to improve their eating and activity during pregnancy, compared to usual obstetric care. The goal of the program is to enhance the health of African-American mothers and their babies.

This randomized controlled study evaluates the effect of individualized physical activity on prescription (PAP) in older overweight adults. The primary hypothesis is that an individualized prescription of physical activity increases physical activity level in overweight older adults after 6 months. Secondary hypothesis are that the increased physical activity level will improve cardio metabolic risk factors and quality of life. 200 women and men, aged 65 with low physical activity level, overweight, and abdominal obesity, will be randomized to an intervention group or a control group. The control group receives general information about physical activity and registration of physical activity level for one week. The intervention group receives in addition an individualized physical activity on prescription with patient-centered counseling. After six months both groups go through the same health check-up as at baseline and follow-ups take place after 12 and 24 months.
