The Influence of Water Intake on Food Intake at Meals Varying in Moisture

The primary purpose of this study is to investigate the influence of including water as a beverage at a meal on food intake, and if the influence of water consumption on food consumption is moderated by switching behavior. Additionally, other individual characteristics will be examined for their influence on the effects of simultaneous variety and portion size on meal intake.

Children s Growth and Behavior Study

Background: \- Studies show that many factors affect children's eating behavior and health. These include sleep, mood, thinking skills, and genetics. Studying children over time may identify children at higher risk for eating-related health concerns. Objective: \- To understand how genes and environment influence eating behavior and health over time. Eligibility: \- Children ages 8-17 in good general health. Design: * Screening visit 1: Medical history, physical exam, body measurements, and questions. * 14 days: Participants will wear a wrist monitor and answer smartphone prompts about eating and mood. They may give a stool sample. * Screening visit 2: * Body measurements. * Saliva, urine, and blood samples. * Heart tests. * Meals provided (after fasting overnight). * Questionnaires and interview. * Behavior, thinking, and exercise tests. * X-ray of left wrist and full body.\<TAB\> * Some parents may have medical history, physical exam, and questions at screening visits. They may answer questions at the yearly visits. * Participants will have up to 6 yearly visits. They will give a urine sample and body measurements, and repeat the X-rays. They will have questions and behavior and thinking tasks. They may give stool samples. Visits will range from 3 to 8 hours. * Participants may choose to participate in other studies: * Stress and Hormones, 1 visit: While resting, participants will give saliva samples and have their heart monitored. Then they will do math. They will repeat the resting part, then do a computer task. * Brain Imaging, 2 visits: Twice, participants will perform tasks with a magnetic cone on their head then answer questions. Once, they will have an MRI, lying still in a scanner with a coil on their head. Before the first visit, participants will collect at-home saliva samples once a day for three days. During both visits, participants will perform tasks and answer questions that gauge their thinking skills and mood. * Experiment 3 (sleep/fatigue): Participants will complete 2 additional visits. During these visits, participants will complete a task on the computer for 2 hours, or watch a movie for two hours. After completion of the task/movie, they will answer questions and be provided with food. Participants will be compensated for the time and inconvenience involved with completing study procedures.

Eating Behaviors in Children and Adolescents With/Without Celiac Disease

This observational study investigates the prevalence and severity of disordered eating behaviors in adolescents aged 11-17 years with celiac disease. Participants complete validated self-report questionnaires (Youth Eating Disorder Examination Questionnaire, YEDE-Q, and Parent Eating Disorder Examination Questionnaire, PEDE-Q) and a structured clinical form. A healthy control group, matched by age and sex, is included for comparison. A longitudinal sub-cohort diagnosed with celiac disease \<6 months prior will be followed at 6, 12, and 24 months to evaluate changes in eating psychopathology and associated clinical variables.

Addressing Weight Bias Internalization to Improve Adolescent Weight Management Outcomes: Randomized Pilot Trial

Weight stigma and weight bias internalization (WBI) are common among adolescents at higher weight statuses. WBI is associated with negative physical and mental health outcomes. The current study aims to test an intervention for weight stigma and WBI combined with an evidence-based adolescent weight management program. Eligible adolescents (13-17) will be assigned by chance to one of two groups: 1) a 4-week intervention focused on weight stigma and WBI followed by a 16-week behavioral weight management program; or 2) a 4-week health information control (to include non-weight-related health promotion topics such as smoking and skin cancer prevention) followed by the same 16-week weight management program but without the WBI and weight stigma content. Study outcomes will be assessed at the 4-week and post-treatment (20 week) timepoints.

Non-Diet Nutrition Education and Its Effects on Eating Behavior, Body Image, and Well-Being in Adult Women

The goal of this clinical trial is to evaluate whether a non-diet nutrition education program can improve eating behaviors, body image, and well-being in normal-BMI women aged 19-35 years. The main questions it aims to answer are: * Does participation in an 8-week non-diet nutrition education program improve eating behavior, body image, and well-being over time in the intervention group compared to the control group? * Is there a significant difference between the intervention and control groups in eating behavior, body image, and well-being after the intervention? Researchers will compare an intervention group receiving an 8-week non-diet nutrition education with a control group receiving no intervention, to see if the program leads to improvements in psychological and behavioral outcomes without focusing on weight loss. Participants will: * Complete pre- and post-intervention assessments, including validated questionnaires on eating behavior (DEBQ, FCQ, IES-2), body image (BAS, Stunkard Figure Rating Scale), and psychological well-being (WHO-5, Rosenberg Self-Esteem Scale), as well as a 3-day food diary. * Be randomly assigned to either the intervention group (8-week online non-diet nutrition education sessions) or the control group (no intervention). * Engage in 8 weekly, 60-minute sessions focused on intuitive eating, body acceptance, and health-promoting nutrition.

Nature for Body Image

Nature exposure has been found to be particularly beneficial for body image, as recent studies have identified a positive association between time spent in nature and positive body image. Positive body image, defined as the ability to accept and respect one's body, has been linked to greater life satisfaction and engagement in healthy behaviors. Conversely, negative body image is recognized as a public health concern due to its detrimental effects on both physical and mental health. It has been associated with symptoms of Body Image Disorders (BIDs), including Eating Disorders (EDs) and Body Dysmorphic Disorder (BDD). The Nature for Body Image (NBI) project aimed to examine the impact of a structured nature exposure intervention on improving body image among young women aged 18-35 years.

Pediatric Feeding Disorder Evolution in Amiens University Hospital

Pediatric feeding disorders (PFDss) affect children with age-inappropriate oral intakes lasting at least 2 weeks, associated with medical, nutritional, psychosocial or feeding skills dysfunction. Feeding is a complex function involving the digestive tract, and different structures. It evolves throughout the child's development. It involves the caregiver-child relationship. Dysfunction of one or more of these systems may be the cause of pediatric feeding disorders. PFDs affect 25% of children, 5% with severe forms. PFDs can have severe nutritional consequences. They often cause malnutrition, even undernutrition, and sometimes overweight.

Supper Heroes: Examining the Impact of an Online Eating Intervention for Families

This study will examine the effectiveness of the online family-based program focused on sustainable eating compared to weekly emails about environmentally friendly behaviours.

Yoga 4 Body Image (Y4BI): Investigating the Impact of Yoga on Body Image and Eating Behaviours

The practice of yoga can positively impact body image, a psychological construct encompassing perceptual, emotional, cognitive, and behavioral aspects, which can be either positive or negative. Negative body image manifests as extreme dissatisfaction with one's body-a condition particularly common among young women-that places them at significant risk for developing Body Image Disorders (BIDs). In contrast, positive body image is characterized by an overall respect for one's body. Current research on the impact of yoga on body image has several limitations, making it challenging to determine whether yoga practice truly has a positive effect on body image and to identify the mechanisms underlying this impact. To address these gaps, the present project aims to overcome the limitations of existing studies by investigating the impact of yoga on body image through quantitative methodologies and by exploring the mechanisms that drive this effect. The project consists of two phases: 1. Investigating the impact of yoga on body image (both positive and negative) and eating behaviours in a population characterized by high levels of body dissatisfaction-young women. 2. Examining the psychological mechanisms underlying yoga's impact on body image, including increased interoceptive awareness, embodiment, and self-compassion, as well as a reduction in self-objectification.

Improvements in Daily Activity and Exercise in School Children: the ActChild Study

The goal of this clinical trial is to assess the health-related effects of an exercise intervention in children aged 5-8 years. Main research questions: * Does a municipality-driven exercise intervention improve physical activity levels in children? * Does a municipality-driven exercise intervention improve sleep parameters in children? * Does a municipality-driven exercise intervention improve eating behaviors in children? * Does a municipality-driven exercise intervention improve quality of life in children? Study Design: Participants will be assigned to either: * Intervention group: Attend 1-2 weekly sessions of 45-60 minutes of child-friendly exercise for 1 year. * Control group: Receive no intervention. Data Collection: Participants will: * Complete questionnaires at baseline, and at 1-year, 3-year, and 5-year follow-ups. * Wear accelerometers for 7 consecutive days at baseline, and at 1-year, 3-year, and 5-year follow-ups.
