Active clinical trials for "Obesity"

Obesity represents one of the most important public health issues according to the World Health Organization and it has reached epidemic proportions globally. The prevalence of childhood obesity has rapidly increased over the past decade and is associated with multiple co-morbid disease states . It is estimated that approximately 15.5% of children and adolescents are obese with a body mass index of ≥95th percentile for age . This not only poses health concerns for the patient, but also places increased demands on our healthcare system that is already overwhelmed by burgeoning costs. Moreover, obese children and adolescents who maintain excessive weight as adults are predisposed to cardiovascular disease and premature death. In carefully selected patients who have failed to lose weight by diet and exercise, bariatric surgery provides an option to obtaining a healthy weight. It is increasingly becoming an attractive option, with the number of adolescents undergoing bariatric surgery in the United States tripling between 2000 and 2003. Obese patients are often afflicted with multi-organ dysfunction and obstructive sleep apnea, which presents unique challenges to the anesthesiologist managing their perioperative care . Bariatric surgery in obese adolescents may be associated with significant postoperative pain. Potent intravenous opioids such as fentanyl and morphine are at the mainstay of perioperative pain management. Unfortunately, respiratory depression and airway obstruction can often occur following administration of opioids in obese patients . This makes providing a safe analgesic regimen difficult during the perioperative setting. As opioids can be associated with respiratory depression and upper airway obstruction, surgeons and anesthesiologists alike must reconcile the adequacy of pain control with the risk of respiratory complications after surgery in obese adolescents.

The primary aim of this study was to examine weight reduction in primary care in obese or overweight subjects with a comorbidity that would benefit from weight loss during 1-year comprehensive lifestyle management programme including medical examinations, personalized dietary and exercise advice, guidance on shopping behaviour and food preparation, and group discussions.

Guidelines from the American Thoracic Society strongly recommend interval warm-up exercise before planned exercise to reduce exercise-induced bronchoconstriction severity. However, no empirical data on the effects of interval warm-up exercise on exercise-induced bronchoconstriction severity are available in obese asthmatic children, where excess fat exerts such an unfavorable burden on the respiratory system, particularly during exercise. The objective of this study is to investigate the effects of interval warm-up exercise on exercise-induced bronchoconstriction severity in obese and nonobese asthmatic children. Our approach will be to investigate exercise tolerance, respiratory function, and exercise-induced bronchoconstriction severity and the effects of (1) 8x30sec interval warm-up & (2) pretreatment with a bronchodilator compared with a no-treatment control on exercise-induced bronchoconstriction severity in 8-12 yr, prepubescent, obese and nonobese asthmatic children. [Aim]: To investigate the effects of interval warm-up exercise on exercise-induced bronchoconstriction severity. [Hypothesis]: Interval warm-up exercise will reduce exercise-induced bronchoconstriction severity after an exercise challenge test to a similar extent as bronchodilator and better than control.

This is a single site, double-blind, randomized, crossover study designed to compare the effects of dietary supplementation with flax oil rich in alpha-linolenic acid (ALA) and fish oil rich in docosahexaenoic acid (DHA) on oxylipin profiles over time (0 to 4 weeks) and among obese females varying in their inflammatory state. Additional assessments will include plasma fatty acid composition, adipokines, markers of adipocyte dysfunction and inflammation; immune cell/monocyte fatty acid composition, and functional properties including their metabolism and oxylipin production; and vascular function.

Approximately 17% of US children have obesity resulting in significant childhood co-morbidities and increased lifetime risk of adult obesity, diabetes, cardiovascular disease and cancer. Guidelines recommend intensive lifestyle programs as first-line treatment, yet few pediatric practices are equipped to provide this. Clinical-community partnerships are well-positioned to address this care gap. This proposal aims to assess whether a community-delivered lifestyle program offered in adjunct to primary care obesity management is feasible, acceptable, effective, and easily implemented in a rural care setting. In this study, approximately 40 children aged 7-13 years old and their caregiver pairs will be recruited from a primary care pediatric clinic. Child-adult dyads will participate in a 24-week program that includes 2 phases, a 12-week usual care phase and a 12-week intervention phase. The intervention phase will include bi-weekly meetings of a community intensive lifestyle program which focuses on healthy diet, daily physical activity, self-esteem and support for individual and family behavior change. A mixed-methods approach using qualitative interviews and study questionnaires, combined with objective measures of adiposity and fitness will assess study outcomes.

It is well known that steam onion have benefit effects on controlling the blood sugar, triacylglycerol (TG) and total cholesterol (TC). In this study, the jeju steam onion examined whether it has beneficial effects on reducing body fat of overweight or obesity subjects.

Childhood obesity is a global health issue. Mexico has been considered as the country with the higher number of children with obesity. There are not approved drugs to support diet and exercise as the first step to lose weight. Animal models and clinical trials in adults have provided evidence about safety and efficacy of interventions such as: prebiotics, curcumin, and omega- 3 fatty acids. The hypothesis of this study is: that non-pharmacological alternatives could support diet and exercise to decrease the weight of children with obesity.

The investigators propose a study to evaluate the success of a bicycle distribution program in increasing physical activity level, decreasing sedentary activity levels and positively affecting body-mass index (BMI) in participants aged 6 to 12 years old with overweight or obesity, who do not already own a bicycle, and are patients at the Children's Hospital Colorado Child Health Clinic (CHC), Lifestyle Medicine Clinic, or Rocky Mountain Youth Clinics. The investigators anticipate that the receipt of a bicycle will increase physical activity level, decrease sedentary activity time and decrease or stabilize patients' BMI. The investigators will answer this research question by distributing bicycles to 525 children and conducting follow up visits over the course of a year to measure the outcomes of interest.

The objective of the present study was to examine the effectiveness of a computerised decision-support tool, developed to assist paediatric clinicians in delivering personalised nutrition and lifestyle optimization advice to children and their families, as a means of childhood obesity management.

To initiate a low-carbohydrate, high-fat (LCHF) or ketogenic dietary (KD) intervention among a cohort of outpatients with either schizophrenia or bipolar illness who also have metabolic abnormalities, overweight/obesity, and/or are currently taking psychotropic medications experiencing metabolic side effects.
