Active clinical trials for "Overweight"

To investigate the effects of different amounts of exercise on both cardiorespiratory fitness and risk factors for cardiovascular disease in sedentary, overweight, mildly hypertensive, but healthy, postmenopausal women aged 45 to 75 years.

This is a retrospective, descriptive study that involves de-identified data consisting of weight changes, pertinent vital signs and laboratory values influenced by body weight, and healthcare utilization of patients prescribed lorcaserin at The Center for Weight Management at the Scripps Clinic in San Diego, CA.

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.

Behavioral obesity treatment (BOT) produces clinically significant weight loss and health benefits for many individuals with overweight/obesity and cardiovascular disease (CVD). Yet, about half of patients fall short of expected outcomes and most experience gradual weight regain, thus negating the benefits over time. Lapses (i.e., self-reported eating instances that deviate from the BOT prescribed diet) could explain poor outcomes, but the behavior is understudied because it is difficult to assess in-lab and via self-report. The investigators therefore propose to study lapses using a multimethod approach with the following tools: ecological momentary assessment (EMA; repeated sampling method via mobile device), a wrist-worn device that automatically detects eating behavior and various eating characteristics (frequency, rate, and duration of eating episodes), and 24-hour dietary recalls. The investigators will recruit participants (n=40) with overweight/obesity and one additional CVD risk factor to enroll in a 12-week BOT program and an additional 12-week period of weight loss maintenance. Participants will complete a biweekly 7-day EMA protocol to self-report on eating behavior, including the occurrence of dietary lapse. Participants will continuously wear the wrist-worn ActiGraph Link to characterize eating behavior. Lastly, participants will complete 24-hour dietary recalls via structured interview (split between days with and without lapses) at 6-week intervals to measure the composition of all food and beverages consumed. This study aims to 1) identifying characteristics of lapse behavior by measuring passively-sensed timing, duration, frequency, and rate of eating amongst known lapse episodes, 2) test the association between dietary lapse frequency and weight change, and 3) estimate nutrition composition of dietary lapses. The study approach is consistent with priorities of NHLBI to optimize clinical research and diagnostic strategies to improve CVD and related risk factors.

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.

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 purpose of this study is to test in overweight and inactive adults whether the new PAI eHealh APP leads to better adherence to a physical activity regimen than the wearable step counter App from the market leader FitBit, and to evaluate if improved adherence will be reflected in a better cardiovascular profile in this group.

The study was aimed at investigating the relationship between body composition and thyroid hormone levels in overweight and obese subjects (BMI≥25 Kg/m2)
