Active clinical trials for "Obesity"

The purpose of this feasibility study is to provide safety data on the implantable Exilis gastric electrical stimulation (GES) system, to individually adjust stimulation parameters to levels that are comfortable for implanted subjects during chronic daily treatment, and to collect data on acute gastrointestinal function and food intake responses to GES during in-clinic testing.

Given the prevalence of overweight and obesity, worksite-based health promotion programs have been recommended due to their potential reach and social support impact. Within worksite contexts, many strategies to prevent and treat obesity have focused on educational programs delivered in person or to small groups that target knowledge acquisition and strategies targeted at individuals to improve their dietary and activity practices. These programs have been criticized because they typically reach a small percentage of workers-and seldom those that could benefit most, are of short duration, and have typically small effects that are not sustained. They have also typically been conducted in large worksites that have the greatest resources. The lack of success of these programs may be due to: 1) inadequate intervention intensity, 2) implementation challenges, and 3) a lack of theoretical models as the bases for intervention development. To overcome the limitations of previous research we will conduct a 2 group randomized controlled trial to determine the reach and effectiveness of an extensive intervention that: (a) is based upon sound theory, (b) is delivered primarily through scalable interactive technologies, and (c) leverages the existing organizational and environmental context of the workplace.

The purpose of the trial is to assess the effects of combining regular, generous intakes of high quality protein (primarily from lean pork and other animal source proteins) with calorie restriction on functional status and lean muscle mass in frail, obese, women who participate in a 6 month intervention and 9 month intervention.

The main goal of this project is to develop, implement and evaluate the 5As Team intervention (5AsT)for healthcare practitioners to improve their weight management patient encounters and improve patient health outcomes. The 5As of Obesity Management suite of tools is a robust, evidence-based approach to weight management, however its implementation and uptake has been heterogeneous in primary care. This project was co-created by, and will be implemented with, our partners the Southside Primary Care Network (SSPCN). A needs assessment on weight management by the SSPCN revealed the need to change provider practice to increase the number of weight management visits. Despite a robust didactic training session on weight management for all providers, which includes the 5As, the uptake in practice has been highly heterogeneous. Thus, the 5AsT intervention to address the implementation of the 5As of Obesity Management in clinical practice was developed by the collaborative team. The SSPCN consists of 25 autonomous groups of multidisciplinary professionals that provide service to a defined group of patients within the SSPCN. The 5As Team consists of multidisciplinary providers (Registered Nurse/ Nurse Practitioner, dietician, mental health worker) who work collaboratively. The intervention is a learning collaborative where these 12 different 5AsTs get together to work to address facilitators and barriers to weight management in their settings over a 6 month period. Half of the teams (N=12) will remain as controls and deliver usual care. They serve as a comparison group for the 5AsTs. This mixed methods study's primary outcomes will assess the change in provider practice and the effectiveness of the intervention and implementation. To assess the impact of 5AsT on patients, we will recruit patients presenting to the central SSPCN programming, We will not intervene directly on patients; we will observe the impact of the 5AsT and SSPCN programming on their health outcomes for a minimum of 6 months, and where possible for 18 months. Data collected includes demographics, weight (BMI), waist circumference, vital signs,and Short Form-12 (SF-12,these measures are routinely measured in the SSPCN), EuroQol-5 dimensions 5 Level (EQ-5D-5L), modified patient assessment of chronic illness (PACIC), and observed adherence to routine clinical care for guideline recommended laboratory monitoring (cholesterol panel, fasting glucose, HbA1c, where appropriate).

The proposed study aims to investigate the effects of laparoscopic gastric plication (LGP) on excess body weight, body mass index, and weight-related medical and psychological co-morbidities in obese adolescents. Additionally, we will evaluate the safety and efficacy of this procedure (implemented within a multidisciplinary comprehensive lifestyle modification program) on changes in the patients' medical status, psychosocial and psychological functioning, physical fitness, and health-related quality of life. Study hypothesis: Laparoscopic gastric plication performed on carefully selected obese adolescents within a multidisciplinary treatment program providing pre and post-surgical behavioral and psychological support and education will result in: a) initial and sustained reductions in excess body weight and body mass index, b) improvements in psychological functioning, physical fitness, and health-related quality of life, and c) reduction in weight-related comorbidities. LGP will be a safe procedure, with complication rates that are comparable to or lower than what has been found in other published reports of surgical weight loss procedures used in obese adolescents.

Specific Aims: The primary aims of this study are to conduct formative interviews with teen mothers to inform a targeted adaptation of empirically based weight management and parent training programs for teen mothers for their preschoolers. To conduct a small pilot and post-pilot focus group of the feasibility and acceptability of recruitment and retention methods & the intervention. Study Hypotheses: Given the small sample size and fact that this is a pilot study, focus will be on estimating effect sizes rather than statistical hypothesis testing. However, the investigators exploratory hypotheses are as follows: (a) The adapted intervention will be more feasible compared to the wellness control condition, with a participant retention rate of ≥80% and an average adherence (attendance at weekly treatment sessions; homework completion 5 weekdays weekly) is ≥ 75%; (b) The adapted intervention will be more acceptable compared to the wellness control condition, based on the Consumer Satisfaction Scale and Therapy Assessment Inventory with ≥90% of the participants responding to the item, "In general how satisfied were you with the intervention?" by choosing "unsatisfied" to "very satisfied." (a) The adapted intervention will result in greater improvements in child behavior and parent-child connectedness compared to the control condition; (b) the adapted intervention versus wellness control condition will result in greater increases in child and teen mother individual as well as joint physical activity and physically active play and greater reductions in individual and joint teen mother and child sedentary behavior (television viewing) from baseline to post-intervention; (c) the greater teen mother and child fruit and vegetable consumption; and reduced child juice and sugar-sweetened beverage consumption from baseline to post-intervention; (d) the adapted intervention versus wellness control condition will result in smaller increases in child BMI percentile and teen mother BMI from baseline to post-intervention; (e) participants who attend higher numbers of intervention sessions will show greater improvements in target outcomes (child behavior, parent-child connectedness, and teen mother and child physical activity, sedentary behavior and BMI); with participants receiving the adapted intervention versus wellness control showing the greatest dose-based improvements.

The purpose of the current study is to determine whether an intensive lifestyle intervention was as effective as surgery to treat morbid obesity nine years post-intervention.

The aim of this study was to compare the effect of a hospital group-based vs. home-based combined exercise-diet program for the treatment of childhood obesity.

The REDUCE Pivotal Trial is a pivotal clinical study designed to develop valid scientific evidence regarding the safety and effectiveness of the ReShape Duo® as an adjunct to diet and exercise in the treatment of obese subjects with one or more obesity-related comorbid conditions.

Childhood obesity is highly prevalent and is associated with both short- and long-term adverse outcomes. Despite availability of guidelines for nearly a decade and more recent comparative effectiveness research (CER) evidence, the health care system has been slow to adopt recommended practices. Although pediatric health care providers often cite barriers such as limited time, skill, and resources, a frequently overlooked barrier is the lack of data systems to efficiently and accurately assess guideline implementation and to improve quality of care for childhood obesity. Health information technology (HIT) offers potential for accelerating the adoption of CER evidence regarding childhood obesity screening and management, for establishing treatment benchmarks, and for supporting patients and their clinical teams in care improvement. Incorporation of HIT may be especially effective if augmented by outreach to parents and children. The goal of this study is to develop and test system-level interventions to accelerate the adoption of CER evidence on childhood obesity screening and management, and ultimately improve obesity-related health care quality and outcomes. To achieve this goal, the investigators will work with two health care systems in Massachusetts with strong track records of research collaboration: Cambridge Health Alliance (CHA), an integrated academic public health system, and Harvard Vanguard Medical Associates (HVMA), a large multi-site group practice. Both systems use an electronic medical record for all aspects of ambulatory care, including point of care services such as electronic order entry and centralized functions such as patient scheduling. In these settings of innovation and commitment to improving quality of care, the investigators will develop and test two systematic strategies for adoption of CER evidence. The first incorporates computerized point of care decision alerts to pediatric primary care providers during routine office visits, linked to CER-based algorithms of care. The second augments this HIT approach with direct-to-parent communication of child's body mass index (BMI) along with recommended evaluation and management. The specific aims of this study are: In 18 community health centers of CHA, to identify barriers to and facilitators of adoption of an existing set of computerized point of care decision alerts for childhood obesity screening and management. The investigators will achieve this aim through in-depth interviews and surveys with primary care clinicians, which will inform the design of the investigators proposed intervention. In 14 practices of HVMA, to conduct a cluster-randomized controlled trial to examine the extent to which computerized point of care decision alerts to pediatric primary care providers, with or without direct-to-parent communications, will increase adoption of CER evidence on childhood obesity for children 6 to 12 years of age with a BMI ≥ 95th percentile. The investigators will determine the extent to which each of the 2 intervention conditions, compared with the usual care control condition and with each other, results in: Increased screening and assessment of childhood obesity at the point of care, including BMI, blood pressure, and laboratory screening, and provision of nutrition and physical activity counseling, A smaller age-associated increase in BMI over a 1-year period, and, Improved specific dietary, physical activity, and sedentary behaviors over a 1-year period. To evaluate each intervention's costs (including clinician and family time) and cost-effectiveness in terms of children's change in BMI and weight-related behaviors. To develop a detailed dissemination guide to further accelerate adoption of CER evidence on childhood obesity in practices and communities interested in implementing similar interventions. To achieve the investigators aims, the investigators have assembled a research team with extensive experience in obesity prevention, clinician and child behavior change, clinical informatics, statistical methodology in cluster randomized controlled trials, cost-effectiveness analyses, and dissemination science. If successful, this project will provide new and sustainable approaches for accelerating adoption of CER evidence for childhood obesity screening and management and for improving quality of care for childhood obesity in pediatric primary care.
