Active clinical trials for "Pediatric Obesity"

This study was a randomized, double-blind controlled protocol in children overweight aged 6-11 years. This study aimed to evaluate the effect of consuming fermented milk products containing Lactobacillus casei strain Shirota (LcS), as a probiotic enriched with prebiotic fructans from A. salmiana or inulin-like standard commercial prebiotic to improve the gut microbiota modulation. After providing detailed information, written informed consent was obtained from parents and written and oral assent from participants before the initial test day. Children were eligible for inclusion in the trial if they were overweight according to the World Health Organization (≥85th body mass index (BMI) percentile for overweight). The trial took place in three full-time elementary schools in San Luis Potosí, México, and the screening of the prospective participants took place up to 1 week prior to the randomization. Children were evaluated over a 6-week intervention period receiving different fermented milk products

In adolescents, conventional obesity treatment comprehensively addresses nutritional, activity, and behavioral topics. Due to limited resources in historically marginalized communities, implementation of nutrition-based interventions that require easy access to fresh food and ability to change the home environment is difficult, which may exacerbate health disparities. It is critical to find nutrition strategies and recommendations that are impactful, sustainable, and cost effective across all communities. There is growing interest in time-based interventions focusing on "when" food is consumed rather than on prescribed macronutrient composition. Time-restricted eating (TRE) is a type of meal-timing which involves fasting for at least 14-hours per day and eating over a 10-hour eating window initiated in the morning, mid-day, or afternoon. TRE recommendations are simple in merely dictating when eating occurs and thus may represent a more straightforward approach for adolescents than other caloric restriction regimens relying on numeracy (kilocalories and macronutrients) and goal setting. In adults, early-day TRE has been shown to reduce body weight, fasting glucose, and insulin resistance. By contrast, restricting food intake to the evening has produced mostly null results or even worsened post prandial glucose levels and β-cell responsiveness. To date, there has been no trial comparing early vs. late TRE on glycemic profiles in adolescents, and it is unclear how meal-timing impacts glycemic profiles in youth. The optimal timing of food intake for adolescents may be very different than adults due to increasing sex steroids and growth hormone levels overnight which may contribute to increased insulin resistance in the early morning. The proposed proof-of-concept study addresses this question by measuring metabolic response to a test meal consumed in the morning, afternoon, and evening among 30 adolescents with obesity using a within participant design. These findings will provide the needed research base for the refinement of TRE interventions in adolescence.

This evaluation evaluated Health Education England's NoObesity digital health app's usability and acceptability to undertake activities improving families' diet, physical activity and weight. The purpose of the study is to evaluate the app's influence on self-efficacy and goal setting and to determine what can be learned to improve its design for future studies, should there be evidence of adoption and sustainability.

This study is a randomized controlled study in a quasi-experimental design in the pre-test post-test design.The aim of this study is to examine the effect of motivational interview applied to obese adolescents on nutritional exercise behavior, anthropometric measurements and sedentary activity level.The data of this study were collected using a personal information form, Nutrition exercise behavior scale, Adolescent Sedentary Activity Questionnaire and anthropometric measurement form.In this study, nursing initiatives include a MG-based training program that will be given to obese adolescents in the experimental group in the form of 6 sessions after collecting preliminary test data. The final tests will be collected after 3 months of follow-up. Pre-test and post-test will be applied to the adolescents in the control group. Each training will take 30 minutes. Various training methods and techniques such as oral expression, question and answer, brainstorming, feedback and powerpoint presentations will be used within the scope of the training program

The overall objective is to explore the mechanisms by which macronutrients regulate food intake and weight gain in Prader Willi Syndrome (PWS). Previous studies from the investigators' labs suggest that the increased appetite of PWS may be triggered or maintained by an increase in the levels of ghrelin, an appetite-stimulating hormone produced primarily by the stomach. This study will compare the effects of low carbohydrate diet versus low fat diet on levels of ghrelin, appetite suppressing hormones and markers of insulin sensitivity in patients with PWS. The investigators hypothesize that the low carbohydrate diet will suppress plasma active ghrelin and increase appetite-suppressing hormones to a greater degree and for longer duration than the low fat diet and will thereby reduce hyperphagia and increase satiety. The investigators also hypothesize that the low carb diet will improve hormonal and metabolic markers (fatty acids, amino acids and organic acids) of insulin sensitivity and inflammatory cytokine profiles of children with PWS.

The goal of the Minnesota center is to integrate primary care, home, and community-based intervention strategies to promote sustained patterns of change in food intake, physical activity, and body weight among low income, ethnically diverse children. A culturally matched family connector will create linkages among the settings to support parents in making home environment and parenting behavior changes conducive to healthy growth and development in their children. Specific Aim 1 To evaluate the effects of a three-year multi-setting parent-targeted randomized controlled intervention on the primary outcome, child BMI, compared to a standard primary care-only intervention among 500 low income ethnic minority two to four year old children who are at or above the 50th percentile of BMI for age and gender. Hypothesis 1: Children in the multi-setting parent-targeted intervention will have a lower BMI at 24 and 36 months, compared with children in the standard primary care only control group. Specific Aim 2 To evaluate the effects of a three-year multi-setting parent-targeted intervention on secondary outcomes, including change in child energy intake and physical activity energy expenditure, compared to a standard primary care-only intervention. Hypothesis 2: Children in the multi-setting parent-targeted intervention will have lower energy intake and higher energy expenditure over the three-year period, compared with children in the standard primary care-only control group. Specific Aim 3 To evaluate the effects of the multi-setting parent-targeted intervention on hypothesized mediators of change in dietary intake, physical activity, and BMI. Hypothesis 3: It is hypothesized that changes in parenting behaviors and the home food and physical activity environment will mediate changes in child energy intake and expenditure, and body mass index (BMI).

The purpose of this 4 week pilot study is to test the use of a mobile application (also commonly referred to as an app) designed to help increase self-management strategies among youth that have asthma and obesity. The data obtained from this study will facilitate refinement of the app and interventional approaches for a future larger scale study to increase youth self-management of their clinical conditions, symptom management, and health maintenance as they transition to adulthood.

The overall objective of the study is to determine the pharmacokinetics of Vitamin D supplementation in children who have asthma and are overweight or obese.

The investigators long-term goal is to increase the number of Summer Day Camps (SDC) that meet the National Afterschool Association Healthy Eating and Physical Activity (HEPA) Standards. The objective is to evaluate the effectiveness of a multi-component intervention designed to increase children's PA levels and improve the quality of lunches and snacks children consume in SDCs. The HEPA intervention is designed to target children, parents, staff, program leaders, and the SDC environment and uses a train-the-trainer model with SDC leaders to train their staff to deliver and integrate the intervention into routine practice. In the proposed study, the investigators will evaluate these HEPA strategies, using a 4-year randomized controlled trial with 20 SDCs. An important feature of the study will be the evaluation of maintenance of the intervention after the removal of research support (e.g., training, boosters) during the final year, as well as costs associated with implementation. The investigators hypothesize that intervention SDCs will achieve significantly greater increases in HEPA, compared to control SDCs. The investigators expect the study to support the cost-effectiveness and maintenance of our strategies for promoting HEPA that will facilitate SDCs meeting newly-established HEPA standards for this setting.

The investigators long-term goal is to advance the adoption and successful implementation of policies that promote PA and nutrition in after school programs (ASP) nationwide. The investigators objective here is two fold. First, the investigators will test the effectiveness of two promising strategies designed to 1) increase the amount of PA children accumulate while attending an ASP and 2) promote changes in the nutritional quality of the snacks served. This represents a fundamental step in establishing practice-based guidelines (best practices) for the uptake and achievement of public health policy goals (CA and Harvard). Second, the investigators will examine the barriers and facilitators to implementing these strategies. The expected outcome of this study is evidence supporting best practices for ASPs to employ to meet policy goals.
