Active clinical trials for "Obesity"

Randomized, double blind, parallel study to assess the effect of a dietary supplement combining polyphenols (hydroxycinnamates from green coffee) and a soluble dietary fiber (oat beta-glucans) in obese/overweight subjects.

The present study aimed to investigate the effects of a single nutritional preventive session previous to a critical period linked to fat gain in university students with overweight and obesity, emulating a nutritional session of a public health system.

This study aims to compare, in subjects with obesity-hypoventilation syndrome (OHS) treated by long-term non-invasive ventilation (NIV), resting energy expenditure (REE) in spontaneous breathing and under NIV. The hypothesise of this study is that REE will be lower under NIV than under spontaneous breathing.

This is a multi-site, randomized, placebo-controlled clinical trial to examine the weight loss efficacy and cardiovascular safety of phentermine 15 mg daily plus lifestyle therapy versus placebo plus lifestyle therapy among 200 adolescents ages ≥10 to <18 years with obesity.

Prevention and early intervention are the most effective methods for influencing eating habits. This study helps fulfill the Department of Psychiatry's missions of clinical innovation and advancing science. Findings will inform future clinical practice, improve the care provided to patients in their important role as parents, and foster interdisciplinary collaborations.

Aims: The principal aim of this study is to evaluate a model of Child Centred Health Dialog (CCHD) in Child Health Services (CHS) aiming to promote a healthy lifestyle in families and prevent overweight and obesity in preschool children. The specific aims are to compare CCHD with usual care and to evaluate the effectiveness and cost-effectiveness of the CCHD for all children and specifically for children with overweight at the age of 4 years and to compare parents self-efficacy and feeding practices in families that received either CCHD or usual care Methods: A clustered non-blinded Randomised Control Trial was set up comparing usual care with a structured multicomponent child-centred health dialogue consisting of two parts: 1) a universal part directed to all children and 2) a targeted part for families where the child is identified with overweight.

The study will demonstrate the relation between muscle tone and viscoelastic properties with the body mass index.

Vitamin B3 has recently been found to be a potent modifier of energy metabolism, especially the function of mitochondria. Mitochondria power up all cells in our bodies, by generating fuel, ATP, for cellular functions. In previous studies, it has been discovered that mitochondrial biogenesis and oxidative metabolism in adipose tissue is severely impaired in obesity, already at a young adult age. Here the investigators describe a proposal where they use nicotinamide riboside (NR), a form of vitamin B3 naturally found in milk, to activate dysfunctional mitochondria, in particular the SIRT/NAD+ pathway, and to rescue signs of obesity-related diseases. The investigators use a unique human study design: monozygotic twins either discordant or concordant for obesity, to examine the effects of NR on mitochondrial function in muscle, adipose tissue and the metabolism of the whole body. The upcoming upcoming results are important for understanding the links between mitochondrial dysfunction and chronic metabolic diseases in humans, as well as for clarifying mechanisms of the novel nutritional therapeutic approaches.

The prevention of overweight and obesity in adolescents is a public health priority given the impact of obesity on both short- and long-term health. Scientific evidence has shown that interventions in diet and physical exercise can reduce the risk of obesity in children and young people since adolescence is an ideal stage for educating on a healthy lifestyle and correcting the habits that may have been acquired in childhood. Smartphone applications (apps) can provide a useful alternative to overweight and obesity prevention measures. The objective of this study was to evaluate, through a randomized controlled clinical trial, the effect of an intervention based on a mobile health application (m-Health) on improving the degree of sport and nutrition knowledge, eating habits, and level of physical activity of adolescents. The sample consists of 305 adolescents, 154 in the intervention group and 151 in the control group that are evaluated at the beginning and 6 months later regarding sociodemographic, eating habits, food knowledge, level of physical activity, body mass index, and waist circumference. The educational intervention was carried out using an m-Health tool, a mobile phone application. The outcomes were changes in the mentioned variables to a six-month follow-up between the two groups.

This study was conducted to compare the effectiveness of care based on the "Accelerated Recovery After Surgery (ERAS) Protocol" and the traditional method in bariatric surgery and demonstrate the difference the two methods based on evidence.
