The purpose of the study is to determine if patients wearing a CAM boot have a change in weight compared to patients who wear a CAM boot and are provided nutritional guidelines and perform upper body exercises.
This is a completely text-messaging based study and all data will be collected via surveys administered on a mobile phone. For this study, we will gather and analyze data on changes in body weight over a 6-month interval in individuals aged 12 and over. This will help us learn more about the normal variation in weight, over time, in the PWS population.
The purpose of this study is to learn if women gain weight using progestin-only methods of contraception and if so, how much. The investigators will look at users of two progestin-only methods: the levonorgestrel-containing intrauterine contraceptive (LNG-IUC) and the etonorgestrel (ENG) subdermal implant, and compare these users' weight change to that of users of a non-hormonal method, the copper intrauterine device. The primary hypothesis is that ENG implant and LNG-IUC users' weight and body composition will increase more than the copper-IUD users. The investigators will collect body composition data using dual-energy x-ray absorptiometry (DEXA), and collect information about diet and activity using validated questionnaires.
In this study, doctors want to find out more about why people who lose weight often regain the weight that they have lost once they resume a regular diet and whether hormones might play a role in weight regain. The study is divided into two parts, called the meal replacement period and the follow-up period. The meal replacement period will consist of drinking a shake for breakfast and lunch and eating a frozen meal for dinner that is calorie controlled. Individuals will also be asked to eat two servings of fruit and three servings of vegetables each day. The study will provide the shakes and the frozen entrees, participants are asked to supply the fruits and vegetables. Participation in this study will last for up to 35 weeks. There will be 10 in-person visits and 13 visits by phone or over Zoom over the 35 weeks.
Background: The indirect effects of the COVID-19 pandemic on mental health are of increasing concern. Perceived stress can lead to binge eating and weight gain. Researchers want to learn more about the relationship between eating behavior and the pandemic. Objective: To study how the stress of the COVID-19 pandemic is affecting eating behaviors and weight. Eligibility: English-speaking adults ages 18 and older who have access to a computer or smartphone connected to the internet. Design: This is an online study. Participants will answer surveys through the study website. Participants will complete a one-time survey. It will ask about their experiences throughout the COVID-19 pandemic, their socioeconomic standing, their mental and physical health, and their eating habits. They will have the option to repeat the survey once a month for the next 12 months. This will show changes in their thoughts and behaviors over time. They will provide their email address to get survey links. Participants will also have the option to complete a 2-minute survey on their smartphone. They will complete the survey daily for 7 days in a row. It will ask about their stress and eating behavior in real time, in their home environment. They will provide their phone number to get survey links via text message. If a participant has taken part in a previous NIH study on the Phoenix AZ campus, they will be asked to share their first and last name, date of birth, and email address. This information will be used to connect data from this study to their past data. Participation is typically 25 minutes but may last up to 1 year. \*\*\*To participate in this study go to the REDCap study link: https://redcap.link/nihcovidstudy.\*\*\*...
The purpose of this pilot proposal are the following: 1) to determine the feasibility and acceptability of integrating the TOPS weight loss program into underserved populations through an urban safety net clinic and 2) to gather preliminary data of weight change to inform the design of a future randomized, controlled trial to determine the efficacy of the TOPS program in safety net clinics. To achieve these goals, the investigators will pursue the following Specific Aims: Specific Aim 1. Assess the feasibility and acceptability of integrating the TOPS program into an urban safety net clinic, with process measures (i.e., recruitment/refusal rates and retention/dropout rates) and focus groups. Hypothesis 1. Integrating the TOPS program into an urban safety net clinic is feasible and acceptable to participants. Specific Aim 2. Assess the percent of participants in the TOPS intervention arm with clinically significant weight change (i.e., weight loss of ≥5% of initial body weight) at 12, 26, and 52 weeks. Hypothesis 2. 10%, 25%, and 33% of participants in the TOPS intervention arm will lose ≥5% of initial body weight at 12, 26, and 52 weeks, respectively.
The primary aim of this study is to examine the effect of applying a minimal contact technology-based intervention (TECH) at 1-year post-bariatric surgery on weight change compared to Standard Care. Forty participants at 1-year post bariatric surgery will be randomized to TECH or Standard Care for a period of 6 months (12 to 18 months post-surgery). Analyses will be conducted to compare these interventions for differences in body weight, body composition, fitness, physical activity, engagement, psychosocial measures, and intervention cost and cost-effectiveness of each approach. TECH will consist of a wearable monitor that provides feedback on energy expenditure and physical activity, electronic tracking of dietary intake, and integration of an electronic scale to provide comprehensive feedback to the participant on all components of weight management. TECH participants will receive a monthly telephone call from the intervention staff to provide guidance on their weight management efforts.
The purpose of the study is to determine if patients wearing a CAM walker boot have a change in weight compared to patients who wear a CAM boot and are provided nutritional and upper body exercise information.
Gestational diabetes mellitus (GDM) is associated with short-term and long-term complications for infants and mothers. The management of GDM during pregnancy focuses on reducing risks to the infant associated with hyperglycemia. The postpartum management of GDM focuses on reducing maternal risk of developing type 2 diabetes (T2DM). A diagnosis of GDM identifies up to 31% of parous women who will eventually develop T2DM and approximately 50% of women diagnosed with GDM will develop T2DM in the first 5 years postpartum. The perceived risk of developing short-term and/or long-term complications of GDM may influence women's likelihood of engaging in diet modification, the mainstay of treatment of GDM, both during and after pregnancy. If sustained after delivery, diet modifications introduced as treatment for GDM could affect maternal weight changes during and after pregnancy, which could in turn affect T2DM risk. It is unknown if and how women with GDM differ in their perceived risk of developing T2DM, dietary choices, or weight gain (and retention) during versus after pregnancy. Therefore, the project proposed in this application seeks to (1) characterize the perceived risk of developing T2DM among women with GDM during and after pregnancy, (2) characterize dietary choices of women with GDM during and after pregnancy, and (3) characterize weight changes of women with GDM during and after pregnancy as compared to women without GDM.
Examining the effect of daily self-weighing on the ability of student to prevent from gaining weight during their four years at Cornell.
This study focuses on lateral hypothalamic area (LHA) deep brain stimulation (DBS) for severe obesity. In a previous pilot study, three subjects were implanted with a DBS electrode into the LHA under an Investigational Device Exemption (IDE) and IRB approved study at West Virginia University. That study demonstrated the safety of DBS of the LHA in these patients. These patients, who met the enrollment criteria of having prior placement of LHA DBS in accordance with previous study protocol, were eligible for this study with a goal of determining optimal DBS settings.
This study will assess the effect of high protein (HP) and high carbohydrate (HC) diets on weight loss and other metabolic parameters. Rationale: The prevalence of obesity is on the rise in the US. The health hazards of obesity have been well established. The detrimental effects of obesity on cardiovascular, metabolic and psychological parameters as well as the excess cost to the national health budget are astounding. One way of treatment and prevention of obesity has been the use of diet and exercise. In the absence of well-established superiority of one diet over another, different scientifically unproven diets are in common use. A palatable diet providing satiety as well as all essential nutrients may go a long way in treating over-weight individuals. Another factor has been the long-term adherence to such weight loss regimens, which in general have been poor. Protein diets have been known to provide greater satiety and reduced energy intake than carbohydrate diets, but definite long-term studies are sparse. For this study the investigators will recruit and study 24 normal, pre-menopausal obese women (12 on HP diet and 12 on HC diet), and compare their weight loss and changes in metabolic parameters between the two diets.
The purpose of this study is to learn whether women who use progestin-only methods of birth control such as the contraceptive implant (Implanon), the levonorgestral-releasing IUS (Mirena), or depot medroxyprogesterone acetate(DMPA) will experience weight change compared to women using the non-hormonal copper IUC (ParaGard). The investigators primary hypothesis is that users of DMPA will gain excess weight and increase their BMI above the copper-IUC users; secondarily, the investigators will compare users' data in the LNG-IUC and ENG implant groups to the copper-IUC group.
This trial is conducted in Europe, and North and South America. The aim of this trial is to investigate if a dietary intervention has an effect on weight when initiating insulin treatment in subjects with type 2 diabetes currently treated with oral antidiabetic drugs (OADs).
SPECIFIC AIM The aim of this study is to determine if increasing calcium intake to recommended levels with dairy foods in adolescent females with habitually low calcium intake and above-the-median body mass index (BMI) for sex and age will decrease body fat gain compared to similar females who continue their low calcium intake. . HYPOTHESIS Post-menarcheal adolescent girls with habitually low calcium intake who consume dairy foods providing at least 1200 mg of calcium per day will have a smaller increase in percent body fat, as measured by dual energy absorptiometry, during one year than post-menarcheal adolescent girls on a usual diet of 600 mg of calcium per day or less.
The purpose of this study is to assess weight change in a population of Veterans with amputations. Little is known about the how weight changes following an amputation. It is widely believed that many patients experience weight gain following amputation. This study aims to identify magnitude of weight changes following amputation and determine characteristics associated with weight gain. Information on weight change trajectories would be useful to better understand long-term health consequences associated with amputation and to design and target interventions to encourage weight maintenance and general health promotion for groups at high risk of weight gain.
The primary objective of the study is to evaluate changes in weight short and long term with bifeprunox and quetiapine. Study participation for the subject is 57 weeks.
The overall aim of this project is to compare protein supplementation on performance, recovery, and body composition changes in adolescent soccer players between the whey protein and the control group in response to the 10-12-week intervention.
The purpose of this study is determine whether different antiretroviral therapy (ART) changes the effects on body fat and predict the weight change in Black and Hispanic females.
Protocol Number: VNI/121/TrimRox: A unique stimulant- and sugar-free TRCAP21 Prodosomed® nutraceutical formulation, TrimROXTM, has been developed in a cGMP and NSF-certified manufacturing facility that is CFR-111 A compliant as well as having a BRC A rating, ensuring compliance with the Global Food Safety Initiative (GFSI). The investigators developed a stimulant- and sugar-free TRCAP21 Prodosomed® nutraceutical technology that effectively addresses directly and indirectly all the contributing factors. The investigators will conduct a 90-day study investigation in 100 study participants to assess the efficacy of TRCAP21 on diverse anthropometric aspects including chest, upper arms, waist/belly, hips and thighs, body weight, height, body mass index (BMI), and overall health and well-being.
This research will test the efficacy of a weight management intervention through a three-group randomized trial: mHealth only, mHealth+Community Health Worker (CHW) support, versus control group, among residents of Boston's public housing developments. The mHealth group consists of a 1-year text messaging program to promote diet and physical activity behavior changes and the CHW support consists of monthly phone counseling delivered by a CHW to support the text messaging program. Our hypothesis is that the mHealth+CHW group will be more effective in bringing about weight loss compared to mHealth alone or the assessment only control group. The findings are expected to inform future health promotion efforts among residents in public housing developments.
This trial will evaluate a healthy eating and weight gain prevention intervention for delivery through calls to the 2-1-1 number.
Heart disease is the leading cause of death in the United States. The overall risk for heart disease is a composite measure of various modifiable factors including blood pressure, cholesterol, and tobacco use; which are exacerbated by a sedentary lifestyle, unhealthy diet, and being overweight. Approximately 32% of the adult U.S. population has high blood pressure and 46% of them have uncontrolled hypertension. Successful management of high blood pressure and other cardiovascular risk is a complex process that requires significant lifestyle changes but adopting and adhering to these changes is challenging. A promise approach to overcoming these challenges is utilizing health coaching. The purpose of this research study is to compare at home devices for blood pressure and weight measurements (DEV) group compared to not using any at home devices Group (NODEV). Both groups will be supported throughout this study by meeting with obesity medicine doctor monthly in office and have a virtual health coaching visits throughout the study duration.
Since severe obesity in youth has been steadily increasing. Specialized pediatric obesity clinics provide programs to aid in reducing obesity. Since the home environment and parental behavioral modeling are two of the strongest predictors of child weight loss during behavioral weight loss interventions, a family-based treatment approach is best. This strategy has been moderately successful in our existing, evidence-based pediatric weight management program, Brenner Families In Training (Brenner FIT). However, since programs such as Brenner Families in Training rely on face-to-face interactions and delivery, they are sometimes by the time constraints experienced by families. Therefore, the purpose of this study is to develop and pilot a tailored, mobile health component to potentially increase the benefits seen by Brenner FIT standard program components and similar pediatric weight management programs.
One in every three children ages 2-19 years is overweight or obese. Although multifactorial in nature, obesity is primarily attributed to a mismatch between energy intake and energy expenditure (EE). Daily EE (DEE) can be partitioned between resting metabolic rate (RMR), EE associated with physical activity, and the thermic effect of food (TEF). RMR corresponds to the energy needed to sustain the body functions at rest and is also related to body composition (i.e., ratio of skeletal muscle mass to fat mass). Skeletal muscle mass is a large contributor to RMR; the more skeletal muscle mass, the higher the RMR (i.e., more energy expended at rest). In addition, muscle plays a central role in whole body protein metabolism and disrupted muscle metabolism is associated with the development of many common chronic diseases associated with obesity such as type 2 diabetes and cardiovascular disease. Although the contribution of disrupted muscle metabolism to chronic disease is well-established in older adults, the potential impact in children is unknown. The overall objective for this primary project application is to determine the role of breakfast protein consumption in improving energy metabolism, energy balance and skeletal muscle health in obese, school-aged children.
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.
For the purpose of this pilot study, the investigators hypothesize that the use of the Step Up Your Game protocol will result in statistically significant improvements in health and athletic performance. The key to this is the coordination of resources from a supervising physician, physical therapist, trainer, dietitian, coach, competitor, role model, psychologist, and spiritual leader. Notably, Step Up Your Game provides resources which would allow patients to find or be their own physical therapist, trainer, dietitian, coach, competitor, role model, psychologist, and spiritual leader. The role of the supervising physician, however, is meant for a qualified professional, who follows the osteopathic approach to medicine, in which the body is treated as an integrated whole, while also working to prevent and treat injuries. Though not limited solely to osteopathic physicians, it is critical to take into account every health aim and injury in the context of the athlete and how these affect all aspects of participants lives.
The purpose of this study is to assess the effects of repeated periods of modified fasting in support of healthy weight management and prevention of weight gain over the winter holiday period (mid-November to early January) in comparison to regular diet and activity.
The study aims to randomize 400 participants to 1 of 3 arms: a) a weight stability intervention prior to smoking cessation (Group 1); b) a weight loss intervention prior to smoking cessation (Group 2); or c) a self-guided weight management prior to cessation (Group 3) and to determine the efficacy of the interventions on preventing weight gain at 12 month follow-up. All 3 conditions receive a highly efficacious behavioral smoking cessation program and 6 months of varenicline pharmacotherapy (ChantixTM), the most efficacious medication for smoking cessation.
This is a prospective, 24-month, longitudinal study of patients planning to undergo bariatric surgery (Roux-en-Y Gastric Bypass or Sleeve Gastrectomy) in which we aim to identify correlates and predictors of observed weight loss trajectories following bariatric surgery. This approach will expand current knowledge by examining the combined impact of empirically supported behavioral and biological data in a large sample over time. Intensive measurement of problematic eating behaviors, mood, and compliance with diet and exercise regimens post-surgery will be analyzed in the context of lterations in parallel with, or in response to, changes observed in the gut microbiota. Identifying these post-surgical predictors of weight loss and comorbidity resolution will allow for the development of individualized interventions to optimize surgery-related outcomes.
