Filter by:The aim of this pilot feasibility and acceptability, randomized clinical trial will be to examine the effects of two-time restricted eating (TRE) interventions on weight loss maintenance (WLM). This study will be conducted in 40 individuals with non-surgical weight loss of ≥5% initial body weight recruited from the NYU Langone Health Weight Management Program and NY-MOVE! Weight Management Clinic at the Manhattan VA. Measurements will occur at baseline, 4 and 12 weeks. Participants will be randomized with equal allocation to 2 groups: (1) TRE6 or (2) TRE10. The TRE6 will restrict their eating window to 6 hours per day and the TRE10 to 10 hours per day.
This study aims to examine the comparative effectiveness of different exercise frequencies (once-a-week vs. thrice-a-week) for reducing liver fat in centrally obese adults with non-alcoholic fatty liver disease (NAFLD), with weekly exercise volumes aligned with the World Health Organization's physical activity recommendations.
The objective of this proposed study is to collect initial efficacy data on a telehealth parent-based behavioral program for children with autism and overweight or obesity (PBT-A), compared with health education (HE).
Croatia is according to statistical data one of the countries in the European Union with the highest percentages of overweight and obese inhabitants. Since the nature of obesity is multifactorial, a multidisciplinary team should treat it in a comprehensive way. A healthy lifestyle, based on the promotion of a particular dietary pattern, regular physical activity, psychological support, education, and small group intervention results in weight loss. We are aiming to develop a five-days small group-based lifestyle modification program on weight loss that would be appropriate in the general practice and outpatient setting facilities. A structured 5-day lifestyle modification program led by endocrinologists-diabetologists together with a nutritionist, a psychologist, and a kinesiologist is aiming to educate on lifestyle modification necessary to lose weight.
Many adolescents find it challenging to adhere to conventional treatment for pediatric obesity because they require daily calorie counting, easy access to fresh food, and the ability to change the home environment. As such, adherence is poor which limits efficacy. One simpler and promising approach is limiting the timing of eating, instead of changing the food quality or quantity. This approach is called, Time-restricted eating (TRE) and involves eating over an 8- to 10-hour eating window and fasting for the remainder of the day.
The purpose of this research is to gather information on the safety and effectiveness of Endoscopic Sleeve Gastroplasty (ESG) for weight loss in a population of obese ulcerative colitis (UC) patients undergoing colectomy with eventual Ileal Pouch Anal Anastomosis (IPAA) compared to counseling on diet and lifestyle interventions alone.
Sarcopenic obesity (SO) has synergistic detrimental effects on elderlies' health. It greatly increases the risk of cardio-metabolic diseases, physical impairment, institutionalization, and mortality when compared with sarcopenia or obesity alone. Effective interventions to simultaneously increase muscle mass and decrease fat mass are challenging but highly warranted. Research showed that exercise tends to produce better outcomes in SO than nutritional interventions. Inconsistent effects of nutritional interventions may be due to a short intervention duration and participants' poor compliance with nutritional advice. Participants' adherence to a dietary regimen is essential to the success of nutritional interventions. Behavior change techniques grounded in a tested effective theoretical model - the Health Action Process Approach [HAPA] model at improving participants' self-efficacy should be incorporated in a diet modification intervention.This project aims to investigate the effects of a HAPA-based individualized dietary behavior change (IDBC) intervention and exercise training, in combination and separately, for elderly with SO, to improve their body composition and physical functions. In this four-armed randomized controlled trial, investigators will recruit and randomize 380 elderly with SO to one of the following four groups: the combined (COMB) group, receiving the 24-week combined intervention consisting of the IDBC program and exercise training, the EXER-only group, receiving only the exercise training, the IDBC-only group, receiving a combination of the IDBC program and health talks, and the control group, receiving only health talks with no other intervention. Investigators will use health talks to control the group and social interaction effects of the group exercise training for the COMB and the EXER-only groups. Investigators hypothesize that participants in the COMB, EXER-only, and IDBC-only groups will have significantly better outcome measures middle of the intervention (T1), immediately (T2), at 3-months (T3), and 6-months (T4) post-intervention than those in the control group when compared to baseline (T0). Investigators will use mixed-effects modeling to compare changes in all outcome variables at the three post-tests among the four groups. If our intervention is effective at mitigating or preventing such occurrences, the impact on public health will be significant. A similar intervention for other populations.
Rationale: Weight loss therapies should aim to reduce fat mass while preserving both muscle mass and muscle strength. Consequently, there is a need for validated methods to measure muscle mass and strength. Current methods are either expensive and require trained technicians, or have not been validated in populations with class II/III obesity (BMI > 35 kg/m2). In our previous studies (MUST-MOP and MUSCLE study), we have validated the use of ultrasound (US) for the measurement of lean mass (a proxy for muscle mass) in a population with obesity. These studies showed that the use of US for the measurement of lean mass was feasible, reliable and valid. The aim of the current study is to validate the use of US for the measurement of lean mass after weight loss in a population of bariatric surgery patients. Objective: Primary objective: To assess the validity of US to measure lean mass after weight loss in a population of bariatric surgery patients. Secondary Objectives: - To assess de differences in lean mass between DXA and US in this study compared to the MUSCLE-study. - To assess how the lean mass has changed after bariatric surgery and the effects of lean mass on total weight loss and resolution of comorbidities - To assess whether the change in lean mass has an effect on serum levels of markers for muscle mass. Study design: This study is an observational follow-up study of the MUSCLE study and will take place in the Centre Obesity Northern-Netherlands (CON) at the Medical Centre Leeuwarden (MCL). Study population: The population will consists of participants, who have participated in the MUSCLE study and have received bariatric surgery at the CON / MCL. Main study parameters/endpoints: The main parameters of this study are: lean mass measured by DXA and US. The main endpoint of this study is the validity of the US measurement of lean mass compared to DXA. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: There are no direct benefits for the participants. However, the results of this study can help to further validate the ultrasound as a cheaper and more accessible method to measure muscle mass. This can potentially be used in standard clinical care to assess muscle mass of patients during weight loss. • The additional time investment: during first year follow-up appointment approximately 30 minutes. The risks of most test are minor, even the small amount of radiation exposure, which means the risks and burden of this study outweigh the potentially obtainable knowledge.
The goal of this observation study is to assess whether endoscopic ultrasound shear wave elastography (EUS-SWE) may be a useful tool for liver fibrosis screening in patients with elevated body mass index and non alcoholic fatty liver disease as compared to other non-invasive screening modalities, which have traditionally had less accurate results in this population. The main questions it aims to answer are: - Determine accuracy of EUS-SWE for liver fibrosis screening compared to other non-invasive scoring systems, such as the FIB-4 score and Fibroscan in patients with elevated body mass index - Establish optimal stiffness (kPa) cutoffs for liver fibrosis grading for EUS-SWE for this patient population in reference to the gold standard liver biopsy, as no standard cutoffs currently exist. Participants will undergo routine endoscopic ultrasound as part of their standard clinical care and indication. Participants are consented for the procedure and undergoing the shear wave elastography. In addition to their standard ultrasound test, it takes on average an extra 2-3 minutes to perform the shear wave elastography. The procedure itself adds no additional risk to the patient and does not expose them to radiation.
The purpose of this study is to determine the effectiveness of mobile health applications in improving health outcomes in patients with overweight and obesity. This study will involve a 6-month long commitment where participants will be expected to use an mHealth app daily, weigh themselves and check their fasting blood glucose levels every morning.
