Active clinical trials for "Obesity"

Obesity is a major cardiovascular disease (CVD) risk factor that is rising fastest in children. Prevention of its damaging effects should begin earlier before they become irreversible. Pilot data identified novel markers of cardiometabolic dysfunction that may be better than body mass index at stratifying risk and as targets for CVD prevention in the young. Advanced imaging, blood tests and a meal-challenge will be used to comprehensively characterise how early metabolic dysfunction (liver and muscle fat, insulin resistance) affects cardiovascular health (arterial stiffness, myocardial energetics, gut vasoreactivity, diastolic function, blood pressure trajectory, left ventricular hypertrophy) in 210 adolescents (110 obese, 50 sedentary normal-weight, 50 high-activity). Reversibility of this phenotype will be tested in the obese by randomised controlled trial, comparing 8-week supervised exercise to a low-activity sham intervention. This study will provide the platform for developing practical, effective CVD prevention in children that is not simply focused on weight-loss.

The obesity epidemic continues to be a major public health concern, impacting nearly one-fifth of US children. One of the most robust predictors of childhood obesity risk is parental obesity and children who are overweight by age 5 are at increased risk for future obesity. A healthful diet is a significant part of preventing overweight and obesity and the home food environment can be a predictor of children's dietary intake. The goal of the proposed pilot study is to examine the feasibility and efficacy of a new family-based approach to early childhood obesity prevention, using optimal defaults in the form of pre-filled, default online grocery shopping carts to promote healthier grocery shopping among families with young children at risk for obesity, potentially influencing the home food environment and dietary intake.

The ambition of the ABEL feasibility study is to test new "green prescription" follow-up models that can get more women with obesity, regularly active, with improved health and physical fitness. The project will evaluate the effect on exercise behavior, total physical activity level and mental and physical health outcomes by four different follow-up models by an exercise professional: HIGH-dosage in-person exercise coaching (four session monthly), MEDIUM- dosage in-person exercise coaching (two sessions monthly) LOW-dosage in-person exercise coaching (one session monthly). The main aim of this study is to evaluate which of these follow-up models is most effective on improving women's exercise adherence, total physical activity level, physical fitness, and mental and physical health. This will be weighed against the cost of each of the follow-up models, in order to identify the best model from a socioeconomic cost-effectiveness perspective. Moreover, the study will identify potential barriers among patients, General Practitioners and exercise professionals that prevents optimal outcome from the current green prescription model.

The goal of this clinical trial is to test a responsive parenting obesity prevention program with infants and caregivers of color (e.g., non-White; Hispanic/Latinx) and/or who are economically marginalized (i.e., publicly insured), delivered via Integrated Behavioral Health (IBH) in pediatric primary care. The main questions it aims to answer are: 1) Is the obesity prevention intervention delivered via IBH in pediatric primary care feasible and acceptable to families of color and/or families who are economically marginalized? 2) Will it prevent rapid weight gain during infancy? Participants will complete baseline (newborn), post-treatment (9 months), and follow-up assessments (12 months). Participants assigned to treatment will receive 4 prevention sessions as part of their typical well-child visit in pediatric primary care. Researchers hypothesize that infants in the obesity prevention intervention will have stable weight gain compared to infants in the control group (treatment as usual) will experience more rapid weight gain.

The aims of this randomized controlled trial are to determine the effects of a lifestyle program that supports weight maintenance and fat mass loss during pregnancy in women with obesity on changes in 1) maternal weight, fat mass, and cardiometabolic risk factors; 2) safety measures, including fetal and neonatal growth; 3) the mediators and moderators of the fat mass loss intervention and 4) the effects gestational fat mass loss has on reducing incidence of adverse obstetrical outcomes, including non-elective cesarean delivery, gestational diabetes, hypertension, and pre-eclampsia.

Maternal and childhood obesity have dramatically increased and continue to present a significant health problem. Studies show that offspring of overweight (body mass index, BMI >25-29.9) and obese (BMI ≥30) women are at increased risk of newborn and age 1-year adiposity, and infant adiposity predicts childhood and adult obesity. The investigators hypothesize that infants of overweight/obese (OW/OB) mothers have both relative hyperphagia and are provided human milk with increased caloric composition, leading to obesity. The investigators propose an intervention study to calibrate milk or formula intake in infants of OW/OB mothers so as to avoid overweight infants at 6 months of age.

Chronic illness is a public health issue and mobility loss is frequent in this population. Among its' multiple physical and psychological consequences, increased mortality and cardiovascular morbidity seem the main concern. Therefore, the exploration of locomotor deficiencies, physical capacities and metabolism of patients with chronic illnesses constitutes a major challenge both for the treatment of causal pathologies, as well as for evaluating the impact of therapeutic interventions, the benefit of which will be an improvement in physical capacities and ultimately mobility. In view of the hypothesis of an increase in the prevalence of mobility disorders in this population, this approach is part of a logic of screening and improving the effectiveness of the care of these patients with a multidisciplinary evaluation of individual risks. The EVALMOB protocol was designed in order to try to determine a standard profile of "dysmobility" in patients with chronic illness

This is a randomized clinical controlled trial (RCT) to investigate the impact of a personalized nutritional intervention on functional and clinical outcomes the first year after traumatic spinal cord injury. The long term goal is to prevent gain of body fat mass and obesity.

Obesity could increase the risk of many chronic diseases, including hypertension, cardiovascular diseases, high lipid level, diabetes, stroke, endometrial cancer and certain types of cancer which could benefit by secondary prevention through screening programs. The World Cancer Research Fund of the American Institute for Cancer Research has reviewed all the studies about the link between obesity and cancer. Studies shown that obesity is an independent risk factor for colorectal, breast and prostate cancer. These three cancers (will be named as "obesity-related cancers" thereafter) demonstrate a rapidly increasing trend of incidence in Asia in the past decade. Among Chinese adults of Hong Kong in 2014, 39% were overweight or obese (compared with 20.9% reported in European adults in the same year) and up to 69.7% reported that they did not perform any measures to achieve optimal weight control. Men (49.6%) had a higher proportion of overweight or obesity than females (29.5%). Adults who are aged 45-54 had the highest rate (50.5%) of overweight or obesity than other age groups. In addition, there were 62.5% whose physical activity level did not meet the recommendations from the World Health Organization (WHO). Only 18.7% consumed at least 5 portions of fruit and vegetables per day; yet about 30% were alcoholic drinkers; and more than 10% were daily or occasional smoker. These figures imply that the incidence of obesity and obesity-related cancers will further escalate - and urgent actions at the community level are needed to combat the rising incidence and mortality of these conditions. According to Hong Kong Cancer Registry, the discrepancy between the number of new cases (incidence) and number of deaths (mortality) is much higher for colorectal, breast and prostate cancer as compared to other cancers. It is well recognized that screening could effectively reduce mortality for these three obesity-related cancers when they are detected at an earlier stage. The concept of a one-stop approach to screen for multiple cancers was found to be feasible, with an ability to detect a wide range of neoplastic lesions at an early stage. In the recent decade, there are also emerging centres that have been established as multi-cancer screening clinics worldwide. Nevertheless, there is a scarcity of studies that have highlighted the outcomes of these multi-cancer screening programs.

This study will evaluate what is the impact of laparoscopy and Trendelenburg position on lung regional ventilation distribution in obese patients, focusing on the differences between the different phases of surgery.
