Filter by:Recommendations for weight management in adolescents with obesity include setting small goals to improve eating behaviours. This frequently includes manually recording food intake over a few days. This is particularly challenging for adolescents as they do not enjoy writing down what they eat, leading to incomplete records. To address this, mobile applications (apps) can easily capture what is eaten through photos. Eating for wellness (E4W) is an app that analyzes photos of meals taken by the user and determines the nutritional profile. The investigators will conduct a pilot randomized controlled trial to determine whether E4W can be implemented successfully and its preliminary effectiveness and impact on dietary intake in adolescents with obesity participating in SickKids' weight management program.
The aim of this study is thus to assess the effect of a chewing gum containing fibres on body weight, metabolism and the oral and intestinal microbiomes in a population of obese children.
There is evidence that obesity prevention programs show positive effects on obesity and lifestyle parameters. However, the effect of the programs delivered by different implementers is unknown, and in Mexico, the available studies present methodological limitations. The aim of this study is to evaluate the feasibility and efficacy of a school-based obesity prevention program implemented by nutrition and physical activity advanced students compared to a control group and implemented by school teachers compared to a control group of Mexican schoolchildren. This is a cluster randomized controlled trial. Schoolchildren from different public schools in Hermosillo , Sonora will be invited to participate. The schools will be randomly assigned to one option:1) the Planet Nutrition Program (PPN) delivered by advanced students, 2) PPN by school teachers, or 3) a control group. A 6-month pilot study with a follow-up at 8 months (after the summer holidays), followed by a definitive study with a follow-up at 8 and 12 months will be conducted.The intervention will consist of nutrition education sessions, physical activity, and the provision of nutrition information for parents. The BMI Z-score, body fat, other obesity, and lifestyle parameters will be evaluated at baseline and at the end of the study. A mixed effects model will be used to evaluate the differences between the groups. The investigators expect that the program could be a model of obesity prevention with a high potential for dissemination in Mexican schools.
Children from rural communities are at greater risk for obesity than children from more urban communities. However, some children are resilient to obesity despite greater exposure to obesogenic influences in rural communities (e.g., fewer community-level physical activity or healthy eating resources). Identifying factors that promote this resiliency could inform obesity prevention. Eating habits are learned through reinforcement (e.g., hedonic, familial environment), the process through which environmental food cues become valued and influence behavior. Therefore, understanding individual differences in reinforcement learning is essential to uncovering the causes of obesity. Preclinical models have identified two reinforcement learning phenotypes that may have translational importance for understanding excess consumption in humans: 1) goal-tracking-environmental cues have predictive value; and 2) sign-tracking-environmental cues have predictive and hedonic value (i.e., incentive salience). Sign-tracking is associated with poorer attentional control, greater impulsivity, and lower prefrontal cortex (PFC) engagement in response to reward cues. This parallels neurocognitive deficits observed in pediatric obesity (i.e., worse impulsivity, lower PFC food cue reactivity). The proposed research aims to determine if reinforcement learning phenotype (i.e., sign- and goal-tracking) is 1) associated with adiposity due to its influence on neural food cue reactivity and 2) associated with reward-driven overconsumption and meal intake due to its influence on eating behaviors. The investigators hypothesize that goal-tracking will promote resiliency to obesity due to: 1) reduced attribution of incentive salience and greater PFC engagement to food cues; and 2) reduced reward-driven overconsumption. Finally, the investigators hypothesize reinforcement learning phenotype will be associated due to its influence on eating behaviors associated with overconsumption (e.g., larger bites, faster bite rat and eating sped). To test this hypothesis, the investigators will enroll 76, 8-9-year-old children, half with healthy weight and half with obesity based on Centers for Disease Control definitions. Methods will include computer tasks to assess reinforcement learning, dual x-ray absorptiometry to assess adiposity, and neural food cue reactivity from functional near-infrared spectroscopy (fNIRS).
The proposed project will test an implementation strategy (the "TrailGuide") for delivering an existing model of pediatric obesity treatment ("Fit Together") that has demonstrated ability to meet published recommendations for improving health outcomes of children with obesity.
The objective of this proposed study is to collect initial efficacy data on a telehealth family-based behavioral program for Latino children with overweight or obesity, which also includes additional caregiver support (PBT-AC), compared with health education (HE).
Black Girls Move is a school-linked daughter/mother physical activity and dietary behavior program, with 9th and 10th grade students. This program is designed to prevent obesity in Black adolescent females and thus aligns with the NIH mission to enhance health, lengthen life, and reduce illness and disability. This project is relevant to public health because it holds the potential to reduce population health disparities impacted by structural racism.
This study will randomize children who have difficulty maintaining a healthy weight to one of two treatment groups: lifestyle therapy plus lisdexamfetamine or lifestyle therapy plus placebo.
Our feasibility study will assess the feasibility and acceptability of Family Navigation (FN) to address attrition (dropout) in pediatric obesity management. Results from this study will help our team to plan a large randomized clinical trial to test the effectiveness of FN in reducing attrition. The investigators will enroll 108 6-to-17-year-olds enrolled in pediatric obesity management clinics in Calgary, AB and Mississauga, ON (Canada). One-half of the children will receive Family Navigation (FN) + Usual Care (UC) for 12 months; the other half will receive Usual Care only for 12 months. Overall, the study will take 2.5 years to complete. For children receiving FN, trained navigators will work with children and their families to reduce barriers that limit their access to health services and support. Navigators will offer extra services and resources, such as parking passes for clinic appointments and supportive text messages between appointments. FN is designed to complement the obesity management (Usual Care) received by children and their families. A Steering Committee with children, caregivers, clinicians, and researchers will be created to refine and improve our FN intervention throughout the study. By having better access to care, children and their families working with navigators may be less likely to drop out and more likely to attend more treatment appointments. Ultimately, the participants may be more likely to achieve success in managing obesity.
The aim of this study is to look at changes in diabetes-related risk factors in Black adolescent girls who are at risk for type 2 diabetes after participating in a 12-wk telehealth lifestyle program.
