Active clinical trials for "Overweight"

The study represents the first effort to prospectively investigate the Melcap's bio-electrical ingestible ODC system in human. The study goal is to evaluate the safety and feasibility of GES treatment in stomach and in the small and large bowel during and following the ingestion of the bio-electrical capsule under tight and controlled conditions.

The goal of this clinical trial is to compare de effect of vitamin K2 in young adults with overweight or obesity. The main questions to answer are: What is the effect of Vitamin K2 supplementation on methylation, serum concentration of ucOC, cOC, Gas6, leptin, inflammatory markers, cardiometabolic risk factors, and cardiovascular risk in overweight or obese young adults? Participants will be assigned to one of two intervention groups where they will consume Vitamin K2 100 µg per day or cornstarch 500 mg per day for 90 days. If there is a comparison group: Investigators will compare the supplementation group (Vitamin K2) with the placebo group (cornstarch) to see if vitamin K2 supplementation modifies methylation, increases serum vitamin K, osteocalcin, growth arrest-specific 6 protein serum concentration, decreases serum leptin concentration, inflammatory markers and reduces cardiometabolic risk factors and cardiovascular risk.

Approximately one half of adults and one-fifth of children have obesity, including 14% of 2-5-year-olds. Early obesity prevention is essential as children who are overweight by age 5 are at increased risk for later obesity. Dietary intake is inextricably linked to weight status, and the majority of young children fail to meet intake recommendations, with socioeconomically disadvantaged and racial/ethnic minority children at increased risk of poor diet quality. However, children's liking of healthier foods predicts their intake, and children can learn to like healthier foods via experience. The current study brings together evidence from the parenting and learning literatures to: 1) examine effects of a novel learning strategy leveraging positive parent-child interactions on 3-5-year-old children's vegetable acceptance and dietary intake, as well as to explore 2) individual differences in learning strategy effects.

The purpose of this study is to assess the effects of an 8-week supervised high-intensity interval training (HIIT) program (vs. physical activity recommendations according to current guidelines) on a comprehensive panel of circulating sphingolipids in middle-aged females and males at elevated cardiometabolic risk.

Data from Abu Dhabi's Department of Health document that the leading cause of death among the population of the emirate of Abu Dhabi is cardiovascular disease (CVD). Even with significant investment of time and resources, this has not improved over time. CVD was the cause of death in over 39% of deaths occurring in patients above 45 years of age. In those older than 60 years of age, CVD causes more deaths than cancer, respiratory diseases, and infectious disease combined. Eating an unhealthy diet is the leading risk factor for CVD-related deaths and one study estimated that the current diet accounted for 72% of CVD-related deaths in the United Arab Emirates (UAE). Interestingly, the limited intake of whole grains was associated with 22% of CVD-related deaths in the UAE. Other risk factors include consumption of processed meat, red meat, and sugar sweetened beverages. Despite recognition of what constitutes healthy diet and exercise practices by survey participants, barriers exist to lifestyle change. In one UAE study of patients with type 2 diabetes, only 3% of the 390 individuals surveyed met numerous guidelines' weekly recommendations for 150 minutes of moderate intensity aerobic activity or 90 minutes of vigorous aerobic activity. The most common reasons given in that study for not exercising included cultural reasons (29.2%), "exercise is boring" (20.3%), and lack of family support (4.1%). Widespread availability and access to outpatient dieticians has not lowered rates of obesity, overweight, and cardiovascular disease risk factors. To the investigators' knowledge, this would be the first study investigating the effect of a package of family based lifestyle interventions guided by a health coach. This package of interventions would be supported by technology such as a smartphone application to record dietary intake and the use of wearable fitness trackers to track physical activity. The nationals of the UAE (called Emiratis),have retained traditional cultural values, including strong ties to extended family, which may lead to better adherence to family based rather than individual appointments and interventions, which could lower CVD risk.

Adverse childhood experiences (ACEs), referring to traumatic experiences occurring before 18 years of age (e.g., abuse/neglect), are associated with a 30-70% increased risk of developing adolescent and adult obesity and obesity-related cardiometabolic comorbidities, which may be due to dysregulation in stress-related physiology and engagement in stress-related behaviors. While adolescents with ACEs have a 2.25 times increased risk of obesity, standard-of-care lifestyle (e.g., nutrition/physical activity) interventions do not typically incorporate trauma-informed care, including assessment and therapeutic attention to effects of ACEs. Heart rate variability (HRV) biofeedback is an evidence-based, relatively brief, mind-body intervention targeting the stress physiology that can be dysregulated in adolescents with ACEs. The objective of this proposal is to adapt and test a 4-session HRV biofeedback protocol for 12-17-year-olds with BMI>85th percentile and ACEs. First (Phase 1), we will iteratively adapt a 4-session HRV biofeedback facilitator protocol with n=3-5 adolescents with overweight/obesity and ACEs, using adolescent quantitative and qualitative feedback to hone and optimize HRV biofeedback for this population (Aim 1). Next (Phase 2), we will conduct a randomized waitlist-controlled pilot study of n=30 adolescents with overweight/obesity and ACEs to assess acceptability and feasibility (Aim 2) and to describe changes in theorized targets of biofeedback (Aim 3).

The purpose of this research is to better understand how people's background, habits, and other factors influence their diets and health.

Today's children are increasingly facing metabolic-related health issues, among which the worldwide prevalence of overweight and obesity is rising at an alarming pace. Childhood obesity is associated with the early onset of chronic diseases including an emergence of prediabetes and diabetes mellitus type 2. The decline of insulin sensitivity already years before puberty, exposes children to long- term complications prior the appearance of clinical symptoms and time of diagnosis. The shortened life expectancy and large economic burden imposed underlines the need for the identification of metabotypes at risk at an early stage. One's genetics, microbial gut composition and every aspect of the environment in which children are raised have been implicated in diet-related obesity rendering metabolomics a very powerful tool towards precision medicine. Yet, the excellence of stool in reflecting the intertwining thereof is completely unexplored for pediatric purposes, whereas blood sampling causing pain and stress for child and parent only captures a narrow fraction of the metabolome. As such, rectal sampling using a customised medical swab for optimal gut metabolome coverage is envisioned. Ambient laser desorption ionisation will be hyphenated to high-resolution mass spectrometry-based metabolomics to provide a framework for elucidating predictive and/or prognostic biomarkers for ever-increasing pediatric metabolic diseases such as obesity and (pre)diabetes.

The prevalence of obesity in the United States has reached alarming proportions with 33% of adults over the age of 20 being overweight. Obesity is more than twice as prevalent, however, in the Pima Indians of Arizona. Although there have been a number of advances in our understanding of the genetics of obesity, the environmental influences on the genetic expression of obesity requires further investigation. In an effort to understand some of the influences on the high prevalence of obesity in the Pima Indians, the present study was designed to investigate eating behaviors and food preferences, most especially the preference for high fat foods, in sib-pairs of Pima Indians who have been previously genotyped in our genomic scan for loci linked to diabetes/obesity. Most specifically, we will utilize several questionnaires and methods of assessing eating behavior and the preference for high fat foods to create a food intake phenotype. In addition, we will study Caucasians so that comparisons can be made between these two groups. We will make these evaluations by assessing eating behavior, food preferences including usual fat intake and preferences for high fat foods, body image perceptions, and energy expenditure. It is hoped that the data gathered from this study will elucidate some of the risk factors for the development of obesity among the Pima Indians.

The IWCR is a global scientific study aimed at better understanding the opportunities and barriers for reducing the prevalence of obesity by collecting information from people who have experience with weight management in their everyday lives. The investigators seek to gather information on a wide range of weight management experiences, ranging from weight loss and weight loss maintenance to weight gain and inability to lose weight.
