Active clinical trials for "Obesity"

This study seeks a better understanding of the pathogenesis of asthma in early life. The aim of this project is to determine whether the offspring of obese mothers at 3 years of life have increased the risk of asthma compared to children whose mothers were not obese and whether this increased risk is associated with a programming altered immune reactivity at birth.

the aims of the present study is to test the PEGASO system in real life conditions in Lombardy (Italy), England and Scotland (UK) and Catalonia (Spain), as well as to assess changes in teen-agers' awareness and lifestyles after the use of PEGASO system. Specifically, the investigators aim to: To test the usability of PEGASO platform To pilot approaches to testing the effectiveness of the system to: Evaluate the increase of knowledge/awareness about healthy habits Assess behavioural change in lifestyle, and specifically on target behaviours In particular, the pilot study will help to assess likely recruitment and retention in a controlled trial, to test the acceptability and utility of assessment procedures, to obtain estimates of effect size and variability to power a future substantive study

This study is designed to investigate the impact of weight loss achieved with the IGB on NASH with early fibrosis in a select cohort of patients with obesity preselected to have a high pre-test probability of having NASH with early fibrosis based on magnetic resonance elastography (MRE)-Hepatogram. In addition, this study will explore potential non-invasive imaging criteria for NASH and early fibrosis using EUS-Elastography.

The investigators hypothesize that compared to the provision of population-based lifestyle advice, providing DNA-based lifestyle advice via personalized nutrigenomics testing (PNT) to two distinct patient populations (Family Health Team patients receiving a lifestyle counselling intervention and transplant recipients) will lead to greater reductions in percent body fat. In addition, it will motivate them to adopt healthier dietary and physical activity habits through changes in attitudes and/or subjective norms and/or behavioural control, lead to greater fat loss (kg), increased percent lean mass and therefore improve health and quality of life outcomes for both patient populations. In addition, it is hypothesized that dietary strategies related to the intake of one or more dietary components of interest will mitigate post-transplant weight gain associated with three SNPs of interest. This is a randomized clinical intervention trial involving a total of four groups of patients (n = 400). The two main patient groups include overweight or obese, stable transplant recipients and overweight or obese patients who are attending group counselling sessions at the East Elgin Family Health Team. Within these two main groups, there will be two sub-groups. Patients will be randomized to receive either PNT or standard nutrition intervention (SNI). Baseline data will be conducted consisting of a food frequency questionnaire and three-day food records using a validated multiple pass method. Bioelectrical Impedance Analysis (BIA) will be conducted to assess body composition and to derive percent body fat and lean mass. Weight and height will be measured using a weigh scale and stadiometer. Attitudes, subjective norms and behavioural control will be assessed using a Theory of Planned Behaviour Questionnaire. Those patients randomized to the PNT group will be instructed on a tailored nutrition care plan and physical activity recommendations based on their individual genetic profile. At the same time, the SNI group will be instructed on general nutrition and physical activity recommendations for weight loss, which include the use of dietary strategies from the standard tool ('Just the Basics') used by registered dietitians for transplant patients and the GLB program for patients attending the East Elgin Family Health Team sessions. Monthly email reminders or phone calls (depending on patient preference) will be sent to transplant recipients as a reminder of their nutrition and physical activity plan. Reminders of nutrition and physical activity goals for the Family Health Team participants are incorporated into the GLB program. Three months, six months and twelve months after baseline data collection and individual nutrition interventions, baseline data will be repeated. After the study is complete, participants in the SNI group will be offered a nutrigenomics report and consultation with a registered dietitian. A paired t-test or repeated measures ANOVA will be used to assess within group change from baseline to each follow-up time point for: BMI, body fat, lean mass, and dietary intake. A repeated measures ANOVA will be used to test between group differences from baseline to each follow-up time point for: BMI, body fat, lean mass, and dietary intake. If significant mean differences are detected, a Tukey's post hoc test will be used to compare differences by group. Statistical significance will be determined by P < 0.05. General linear regression models will be used to assess interactions between each genotype of interest and each dietary component of interest on BMI and body composition from baseline to each follow-up time point.

The current study is designed to measure and evaluate the pharmacokinetic profiling of acetaminophen in the young obese patient population.

1.Objective The investigators aim to determine the effect of brisk walking prescription (> 10000 steps, > five days, per week) on body components and metabolic risk factors among patients with overweight/obesity. The objectives are as follow: The body components changes before/after the brisk walking prescription (> 10000 steps, > five days per week) intervention in overweight/obesity population; The metabolic risk factors changes before/after the brisk walking prescription (<10000 steps or <five days per week) intervention in overweight/obesity population 2.Study design This study is a prospective 4-month follow-up scheme in which patients were treated with the following intervention: > 10000 steps, > five days, per week. For individual follow-up, body components and metabolic risk factors will be tested before and after the study. Every participants will be followed up in community visits every month. 3. Statistical analysis Statistical analysis will be performed using SPSS 16.0 version package (SPSS Inc., Chicago, IL.). Numerical data will be presented as mean ± standard deviation for normal distribution or otherwise median (interquartile range). Two-sided independent t-test is adopted for between-group comparison on end-points with normal distribution, otherwise non-parametric test. Row-Column table will be analyzed through chi-square test. P<0.05 is taken as statistical significant.

The effect of overweight and obesity on IVF outcomes is still questionable. The purpose of this study was to determine if overweight/obesity in women with PCOS were associated with an adverse IVF outcome compared to those with normal weight. Design: Retrospective cohort study.

Background: Obesity is associated with multiple diseases. Bariatric surgery is the most effective therapy for severe obesity that cannot only reduce body weight but also obesity-associated morbidity. Objective: The metabolic alterations associated with obesity and respective changes after bariatric surgery are incompletely understood. Design: In the longitudinal observational study, the investigator applied a 1H-NMR-based global, untargeted metabolomics strategy on human serum samples that were collected before and repeatedly up to one year after distinct bariatric procedures (sleeve gastrectomy, proximal and distal Roux-en Y gastric bypass; RYGB). For comparison, the investigator also analyzed serum samples from normal-weight and less obesity obese subjects that were matched for 1-year postoperative BMI values of the surgical groups.

The purpose of this study is to learn more about why some obese persons are resistant to developing obesity-related metabolic diseases (such as diabetes and cardiovascular disease), while others are prone to developing these conditions. We will do this by studying obese persons before and after a 5% body weight gain. Subjects will be asked to increase their current diet for a period of 8-12 weeks in order to increase their current body weight by 5%. Each will then be asked to maintain this weight increase for 3 weeks. We will monitor subjects throughout this time period with weekly medical evaluations. At the completion of the study, we will provide each subject with a 6-month weight loss program.

RATIONALE: Overweight and obesity have been associated with multiple types of disease, including cancer. Living in a smart growth community may encourage behaviors that would reduce the risk of obesity. PURPOSE: This research study is looking at the effect of a smart growth community on prevention of obesity in middle-, moderately low- and low-income families.
