NCT ID: NCT03524521 Not yet recruiting - Physical Activity Clinical Trials

Body Weight-Based Interval Training in Sedentary Overweight and Obese Adults

Start date: June 4, 2018
Phase: N/A
Study type: Interventional

Body-weight based interval training (IT) performed 3 times per week will lead to reductions in abdominal adiposity and reduce overall body fat percentage in overweight and obese sedentary adults more effectively than moderate intensity continuous training (MICT). Body-weight interval training will improve exercise capacity (peak VO2) in overweight/obese adults.

Online Obesity Treatment in Primary Care (Rhode Island, USA)

Start date: April 9, 2018
Phase: N/A
Study type: Interventional

Behavioral obesity treatment produces clinically significant weight loss; for the greatest impact, it should be made available in the primary care setting where it can reach the many patients with overweight/obesity. The investigators developed a 3-month automated online behavioral weight loss program, Rx Weight Loss (RxWL), and showed that it produces clinically significant weight losses among primary care patients. The investigators' early efforts at pragmatic implementation of RxWL have been promising, and have shed light on challenges associated with implementation, and the need to study longer-term effectiveness. The investigators will therefore conduct a pragmatic study to improve the implementation and effectiveness of this behavioral obesity intervention delivered in routine and representative healthcare settings. The investigators are partnering with the Rhode Island Primary Care Physicians Corporation (RIPCPC), a large primary care network of 58 practices with 100 physicians and 16 nurse care managers. Using the framework for Effectiveness-Implementation Hybrid Designs, the investigators will simultaneously target effectiveness and implementation to maximize the public health impact of the research. Half of the 16 nurse care managers, and the practices they serve, will be randomized to either Basic Implementation (alerts generated using the electronic medical record [EMR] to direct eligible patients to RxWL), or to the Enhanced Implementation (alerts, clinician skills training to motivate and support weight loss, clinician dashboard with reports on patient progress and tools to facilitate patient engagement and behavior change). The investigators will test the hypothesis that the Enhanced Implementation will increase the proportion of patients directed to, enrolling, and completing the weight loss program. Because maintenance of weight loss is a critical problem, this project will also involve randomization of 600 patients with overweight/obesity and type 2 diabetes, hypertension, and/or hypercholesterolemia to the 3 month RxWL intervention followed by one of three maintenance conditions: (a) Control- 9 monthly online education sessions; (b) Monthly Lessons and Feedback- 9 monthly online video lessons teaching self-regulation with automated feedback on the self-monitoring record; (c) Refresher Campaigns- 9 monthly on-line video sessions, teaching self-regulation and providing two 4-week courses with novel strategies and behavioral challenges to improve long-term outcomes. The investigators will test the hypothesis that 12-month weight losses are better with Refresher Campaigns than Monthly Lessons and Feedback, and both are better than Control. Secondary outcomes include changes in weight, CVD risk factors, and medication use over a full 24 months. The project is significant and innovative because: it uses an empirically validated approach to obesity treatment that is integrated into the primary care setting, leveraging existing staff and EMR capabilities; it has a dual focus on improving effectiveness and implementation; it has a pragmatic design in partnership with a large primary care network that treats a diverse patient population; and it has potential to it provides a scalable, sustainable approach that can serve as a model for broader dissemination of obesity treatment intervention.

NCT ID: NCT03482193 Completed - Clinical trials for Overweight and Obesity

Health Literacy and Overweight in Adolescents

Start date: January 2017
Study type: Observational

Obesity in children and adolescents has become a major public health problem in recent years. In Belgium, 20% of people aged between 2 and 17 are overweight and 7% suffer from obesity. While studies often associate this overweight with socio-economic level, other factors, such as health literacy (HL), may also play a role. Among adolescents, some studies have shown an association between the level of HL and the Body Mass Index (BMI). Our study aims to investigate the association between HL of adolescents and their BMI. This is a cross-sectional survey among 9 high schools in a medium city of Belgium, including 254 high school students aged between 12-17 years. Health literacy was assessed by the Health Literacy Measure for Adolescents (HELMA). Student's age, sex, weight, size and parental socio-economic status are gathered in the medical file during the medical examination organized by the schools after obtaining the informed consent of the students and their parents.

NCT ID: NCT03465800 Recruiting - Physical Activity Clinical Trials

Understanding Mechanisms of Exercise Behavior Change

Start date: February 26, 2018
Phase: N/A
Study type: Interventional

This research seeks to examine psychological factors that may impact relationship between incentives and health behavior engagement, specifically physical activity. Additionally, it will compare the impact of two different incentive schedules on behavior engagement, one providing immediate rewards (i.e. rewards received on a daily basis) and another providing delayed rewards (i.e. rewards received at the end of the study period), with an active self-monitoring intervention condition in which no rewards are offered. Study participants will provide reports of their physical activity each day for three weeks, and in the two incentive conditions, they will receive small monetary rewards for their physical activity. Following the three week reporting and reward period, participants will complete two additional assessments, measuring psychological constructs and behavior engagement following the cessation of rewards. The study will also examine how cognitive and anthropomorphic factors may contribute to intervention response and the effects on psychological constructs.

NCT ID: NCT03458533 Recruiting - Metabolic Syndrome Clinical Trials

Changes in the Hypotalamic-pituitary Region of Patients With Metabolic Syndrome and Obesity

Start date: November 2016
Phase: N/A
Study type: Observational

This study aims to identify new morphological and quantitative magnetic imaging parameters of pituitary gland and sellar region in overweight and obese patient at baseline and after 3 years, dividing patients in 3 groups (weight loss through diet and lifestyle changes, weight loss through bariatric surgery, no weight loss)

Adapting an Evidenced-based Weight Management Intervention and Testing Strategies to Increase Implementation in Community Mental Health Programs

Start date: March 2018
Phase: N/A
Study type: Interventional

This is a pilot randomized clinical trial testing an implementation intervention to support delivery of a behavioral weight loss program at community mental health programs.

NCT ID: NCT03448094 Recruiting - Clinical trials for Overweight and Obesity

The Effects of Resveratrol Supplementation on Cognition, Cerebral Blood Flow, Microbiota and Systemic Inflammation.

Start date: February 6, 2018
Phase: N/A
Study type: Interventional

Previous research shows that a diet high in fat has harmful effects on gut health. This increases the chance of developing obesity-related diseases (such as type 2 diabetes) and disrupts cognition and mood. Research has suggested that gut health can be improved by taking certain supplements, including resveratrol (a polyphenol found primarily in red grape skins). Resveratrol has also been shown to improve brain blood flow and possibly brain function - however, there is limited research studying this. This study will investigate the effects of 12 weeks daily consumption of resveratrol on cognitive function, cerebral blood flow, gut microbiota and systemic inflammation in overweight and obese healthy adults.

NCT ID: NCT03447600 Recruiting - Clinical trials for Overweight and Obesity

Diet-Induced Variability in Appetite (DIVA)

Start date: March 1, 2018
Phase: N/A
Study type: Interventional

The aim of this study is to test the hypothesis that dietary weight loss (WL) through alternate day fasting (ADF) will enhance appetite control, health markers and wellbeing following WL compared to standard daily calorie restriction (CR).
