Active clinical trials for "Overweight"

The results from this study may help to explain if incorporating mixed nuts in a reduced calorie diet will lead to weight loss.

Dipeptidyl peptidase 4 (DPP4) is a serine exopeptidase able to inactivate various oligopeptides involved in inflammation, immunity and vascular function. Our aim was to investigate the associations between constitutive levels of DPP4 activity and inflammatory biomarkers, skin microvascular reactivity, gut peptides, insulin resistance indexes, heart rate and blood pressure variability, and measures of adiposity in subjects with different grades of glucose tolerance.

A method has been developed to measure in vivo adipose kinetics and turnover rates, which is a substantive departure from previous indirect and in vitro approaches. This technique involves drinking deuterium (2H)-labeled water, with an initial ramp-up to increase body water 2H enrichment, followed by daily intake to maintain enrichment values. The 2H from the heavy water is incorporated into the DNA of the dividing cells, as well as the lipid component, providing measures of cell formation, lipid synthesis, and adipose turnover. The objective of the proposed study is to enroll women who are overweight (sedentary or physically active) in order to collect 2H-enriched adipose tissue specimens that will be utilized to establish this innovative 2H-labeling protocol at Pennington Biomedical Research Center. This study will also assess adipose kinetics in individuals with different levels of physical activity to better understand the association between in vivo adipose cell kinetics, physical activity, and metabolic health in humans.

The aim of this pilot project is to disseminate multiprofessional group programs (*MGP*) for therapy of the estimated 119'140 overweight/obese children in Switzerland. Family-based behavioral MGPs have been implemented from 2009 to 2013 to determine changes of health and family behaviours, after the intensive phase (*T1*), at 1 and 2 years after start (*T2*, *T3*). MGP costs are reimbursed in Switzerland: 1) if 116 sessions are provided by experts in physical activity, nutrition and psychology; 2) if parents are included and if their adherence is higher than 85%. In the nationwide "Evaluation of Multiprofessional Group Programs for Paediatric Obesity Therapy" (*KIDSSTEP*) study, multiple psychosocial and physical parameters were assessed at T0, T2 and T3 . Out of 33 certified centers, 25 were active and only 19 were re-certified in 2013/2014. Obese children suffer from major co-morbidities and therefore, only one third of referred patients can be treated in MGPs and their beneficial effects on obesity as well as physical and mental health outcomes are sustained over 2 years.

Women with pre-pregnancy obesity, women who exceed recommended weight gain during pregnancy, and children who experience rapid and excess growth during the first year of life are all at risk for subsequent obesity. The purpose of this study is to examine creative cognitive strategies to promote healthy weight gain during pregnancy, creating a sound substrate of metabolic programming for the critical first six months of life. A trans-disciplinary approach utilizing a patient- and family-centered intervention and active patient engagement with counseling for positive gain will work with women to shape lifestyle during pregnancy and postpartum, and when feeding their infants in the first 6 months of life. It is hypothesized patient engagement with counseling for positive gains will successfully mitigate excess weight gain in both pregnancy and infancy compared to usual care. Moreover, data will be examined to assess whether psychological variables, work and school climate, and social support factors influence body weight gain trajectories and/or weight loss during and after pregnancy.

The aim of this study is to acquire impedance measurements of the adult human body with a novel bioimpedance device housed inside a watch case and to compare derived estimates of body composition measured by dual-energy x-ray absorptiometry (DXA) and other bioimpedance analysis (BIA) systems.

The purpose of this study is to estimate antihypertensive effect of azilsartan medoxomil (Edarbi®) therapy on blood pressure in participants with overweight or obesity in routine clinical practice of hypertension (HTN) treatment in the Russian Federation and in the Republic of Kazakhstan..

Aim: The overall aims of this study to look at what changes are seen overweight and obese (very overweight) children, as they get thinner. Specifically the investigators are interested in the chemicals and bacteria that children pass in their urine and stool because looking at how these change as it tells us about how their gut and other bodily systems are adapting. Hypothesis: Metabolic profiling is a useful and accurate tool for observing and monitoring weight loss in children Study plan: To observe this weight loss process in children, the investigators will be attending a commercial weight loss camp called 'MORElife' which takes place every year in Leeds. This camp is attended by children age 8-17years who are overweight or obese, for between two and five weeks. It aims to help them lose weight through a structured diet, exercise, education and support program. The investigators plan to, with the consent of the parent and agreement the child ask if they would kindly give us a urine sample at the beginning and end of their time on the camp. For those staying longer than 2 weeks the investigators will also ask for a sample in the middle if possible. In addition for those children who consent, the investigators will also ask for a small stool (poo) sample at these same time points although there is no obligation to participate at all in the study and it will not affect their time on the camp whatever they decide. Any children who will be attending the MORElife reunion (arranged by the camp at around 10-12 months after) who agree will be asked for a final urine and stool sample to look at the long-term effects. Each sample is given a code so as to remain anonymous, frozen and transported to the university laboratory to be analyzed. With permission and consent the investigators will also collect some information about the children such as, weight and height from the camp coordinators as well as samples of the diet that they will be fed and example of exercise activities to give a full picture so that results can be as accurate as possible.

Patients who are overweight or obese, diabetic or not, share with those who are suffering from uric stones the same way to remove abnormal acidity of the body in urine, ie a kidney ammoniogenesis default. This results in an overly acidic urine pH which is directly pathogenic in people predisposed to develop uric stones because the precipitation of urate soluble uric acid is accelerated in acid medium. Excess visceral fat, particularly perirenal, this defect may promote formation of renal ammonium. Indeed, the perirenal fat is adjacent to the renal cortex and shares with it a common arterial supply via the plexus Turner. Adipokines and fatty acids of the perirenal fat are predisposed to gain the renal cortex, seat of the ammoniogenesis. In humans the pathogenic role of the perirenal fat is demonstrated in chronic kidney disease and essential hypertension. However, the amount of fat and perirenal that of intra-abdominal fat are positively correlated. Investigators hypothesis is that the perirenal fat also exert a pathogenic role in uric because of anatomical links between kidney stones and greasy environment and because excess fatty acids reaching the renal cortex decreases ammoniogenesis in an animal model metabolic syndrome. For the test, the investigators will compare the amount of fat and perirenal renal ability to form ammonium in patients with uric or calcium lithiasis taking into account the amount of intra-abdominal fat.

To determine whether reducing loss of control eating (LOC) with Interpersonal Psychotherapy-Weight Gain (IPT-WG) will be effective for adolescent military-dependents who report such behavior. The investigators will examine whether IPT-WG influences body weight gain trajectories and prevents worsening disordered eating, psychosocial problems, and metabolic functioning among military dependents at heightened risk for adult obesity and disordered eating. This study will provide key efficacy data for a new promising obesity prevention program for youth from military families.
