Filter by:The study design is a prospective observational study in adolescents who are at risk for developing Type 2 Diabetes (T2D), to evaluate the effectiveness of sparkling water to reduce dietary intake of added sugars and thereby improve glycemia. Study data on consumption and the flavor profile of sparkling water will serve as a measure of acceptability. The study intervention will be to provide carbonated flavored sparkling water for 12 weeks to adolescents (and their families) who have a usual intake of 2 or more servings of sugar sweetened beverages (SSB) per day and are at a high risk for developing type 2 diabetes. Study measures will be obtained before and after the exposure to carbonated flavored sparkling water and each participant will serve as his/her own control. To encourage the participants to substitute the carbonated flavored sparkling water, study personnel will send them weekly iMessages through the Technology Assisted Dietary Assessment (TADA) app. In addition, investigators will monitor the participants' diet, using the TADA app, every two weeks, for 4 days. Study measurements will be obtained at baseline, before the intervention, during and at the end of the 12 week intervention. Objective: Determine the effect of reducing added sugars intake by substituting carbonated sparkling water on T2D risk in adolescents. Hypothesis: Adolescents who decrease consumption of SSB by substituting sparkling water will experience decreased blood glucose concentrations and increased insulin sensitivity during an oral glucose tolerance test and decreased glucose excursions during continued glucose monitoring, compared to those who do not decrease consumption of SSB.
The significant increase in the prevalence of obesity can also be attributed to various social changes, in which the environment (political, economic, social, cultural), and not only the individual and his choices, takes a strategic place in the analysis of the problem and proposed interventions. The food environment can influence the choice and consumption of foods that promote obesity, such as ultra-processed foods (UPA). It is suggested that to intervene to effectively change behavior and eating habits, intensive interventions are needed that consider multiple levels that include the family, school, and community rather than one-off interventions that may not be effective in changing behavior and lifestyle. Regarding the family environment, parents or guardians can assist in the adoption of obesity-related behavioral patterns. It is known that the context of Primary Health Care (PHC) is ideal for actions to prevent diseases and promote children's health, since the PHC professional team is closest to the reality of life of the child, family, and community. We emphasize the importance of this study from the perspective of treatment of childhood obesity, in order to generate scientific evidence and practical subsidies for the implementation of interventions focused not only on the individual, but also in the context of the Unified Health System (SUS). The hypothesis of the study is that there will be a decrease in the consumption of ultra-processed foods (UPA) among children, aged 6 to 10 years, living with obesity and who are treated in primary health care. In addition to encouraging healthy habits such as physical activity and the consumption of in natura and minimally processed foods. The management of childhood obesity is one of the priority topics on the national agenda of SUS's food, nutrition, and health promotion policies.
Childhood obesity condition has increased 10 times in the last 40 years, representing one of the most important public health challenges of our century. The overweight and obesity in children are conditions associated with several determinants, mostly related to dietary habits, physical activity, and environmental behavior. To counteract childhood obesity, several prevention programs have been promoted, however evidence concerning their efficacy was contrasting, especially among the younger population and in the long term. Moreover, due to the wide variety of interventions administered it is not clear which specific strategy (or combinations of strategies) was the most effective. The LIVELY study aims 1) to assess the prevalence and the factors associated to childhood overweight and obesity; 2) to develop multidimensional strategies for prevention of childhood obesity by involving families and recognizing the role of schools as an environment for raising awareness on healthy and sustainable dietary patterns and lifestyle.
Obesity in adolescents is associated with the development of cardiovascular disease and type 2 diabetes mellitus. In order to detect early development of cardiovascular disease, early detection of the endothelium of obese adolescents is needed. Endothelium dysfunction is an early stage of developing atherosclerosis, which can be a predictor of cardiovascular disease development in the future. Flow mediated dilatation (FMD) is a non-invasive method that can measure endothelium function and predict the risk of cardiovascular disease, which is not only able to measure artery diameter, but also provides function index of nitric oxide (NO) in the endothelium. FMD is negatively related to BMI. Meanwhile, Endothelin-1 (ET-1) is thought to play a role in the pathogenesis of insulin resistance, because when its levels increase, ET-1 can cause a condition of hyperinsulinemia. ET-1 was found to be high in patients with cardiovascular disorders, as well as in obese and diabetic subjects. Alternative methods for assessing endothelial function by measurement of biomarkers of activation and endothelial dysfunction such as soluble intercellular adhesion molecule-1 (sICAM-1). Levels of sICAM-1 have been found to be related positively to age, systolic and diastolic blood pressure, hypercholesterolemia, hypertriglyceridemia and inversely to estrogen. Furthermore, associations have been found between sICAM-1 and cardiovascular mortality in both healthy individuals and populations at high risk. The aim of the study was to evaluate FMD, concentrations of ET-1 and sICAM-1 in adolescents with a presence of obesity and hypertension and to compare these with controls (obesity and non hypertension), as well as to analyze the correlations between FMD, ET-1, sICAM-1 and blood pressure values.
This project aims to move what is currently a specialty-care model for the management of obesity of children and adolescents into the primary care setting.
This is single-center cross-sectional mechanistic study in lean and obese children with moderate-severe asthma, followed by a randomized, SHAM-controlled trial of Inspiratory Training (IT). The primary outcome is to describe the contributions of inspiratory muscle dysfunction (IMD) and Small Airway Dysfunction (SAD) to obesity-related versus non-obesity-related asthma. The study will involve training (IT) for 8 weeks at three intensity levels (SHAM, low and high). Target dose: 150 inspirations three times weekly. The population includes 6 to 17-year-old children with moderate to severe asthma and with a body mass index qualifying as normal habitus (BMI 5th to 84th CDC percentile) or obese habitus (≥95th percentile BMI and less than 170% of the 95th CDC percentile). Participants will be involved for 10 weeks. The investigators will use analysis of covariance (ANCOVA) to estimate and test the difference in mean values of baseline measures between obese and non-obese cohorts. Covariates will include age, sex (male/female), race/ethnicity, baseline asthma severity (NAEPP step 2 vs ≥3), and atopy status
The GHK intervention was developed according to the United Kingdom Medical Research Council's framework for developing and evaluating complex interventions. A pilot- and feasibility study was conducted during December 2022-April 2023, and the intervention was subsequently adapted and adjusted. The GHK main trial is a two-school-year cluster-randomized school- and community trial designed to investigate the effect of the multi-setting, multi-component GHK intervention program on weight development, health and wellbeing in Danish children aged 6-11 years. The trial will include 24 schools in Denmark (12 intervention and 12 control). The primary aim of the cluster-randomized trial is to investigate whether the GHK intervention program can promote healthy body composition as measured by fat mass (FM) in the intervention group compared with the control group. We hypothesize that the intervention will result in less FM gain in the intervention group compared with the control group over the two school-year study period.
About 380 million children and adolescents suffer from overweight and obesity at the global level. Obesity results from the interplay between biological (sex, age, fetal programming, gut microbiota, epigenetics, and genetics) and environmental factors (e.g., unhealthy diet, physical inactivity, stress). Mutations in genes from leptin melanocortin pathway are involved in "non syndromic monogenic obesity", characterized by severe early onset obesity, hyperphagia and endocrine deficiencies. Exact frequencies of mutation in these genes are not precisely evaluated in french children with severe obesity. Moreover new treatment, such seltmelanotide are avalaible in case of certain mutation, leading to a significative weight loss in treated patients.
The goal of this clinical trial is to evaluate a new way of providing healthcare to children with an unhealthy weight. Families who participate will be assigned by chance to one of two groups. One group will see their child's primary care provider to talk about healthy lifestyles for 6 months. The other group will be in our Healthy Lifestyle program for 6 months. This will include: - Check-ins with lifestyle specialists and community health workers, - A mobile app to help support a healthy lifestyle, and - Access to community programs and activities. The main questions the study aims to answer are: - Do children in the Healthy Lifestyle program have better weight outcomes? - Do more families in the Healthy Lifestyle program stay in the study? - Does the Healthy Lifestyle program work better for families from certain communities?
Participants 13-18 years of age with extra fat stored in the liver will be randomly assigned to a protein supplement or placebo "fake supplement" for 2 months to see if the participants who get the protein supplement have less fat in the liver compared to participants who were in the placebo group.
