Child Obesity

The purpose of this study is to determine the most effective family-centered intervention (FCI) for weight loss and obesity prevention in Hispanic families. FCI is a type of program that involves family (such as parents and caregivers) supporting their children to promote healthy habits.

This is a randomized pragmatic trial of the Community-AHF intervention to evaluate its effectiveness at decreasing body mass index in 5-12 year old children.

Canada's health care system has established numerous clinics over the past 20 years to treat childhood obesity. However, up to 80% of children at these clinics drop out before they finish treatment. This is one of the most difficult challenges in managing childhood obesity, since even the most effective treatments cannot help children who drop out. However, children who stay in treatment longer are more likely to manage obesity successfully. This randomized controlled trial will test whether Family Navigation (FN) helps reduce drop out from obesity treatment. Overall, this study will last 5 years. The investigators will enroll 252 children aged 6 to 17 with obesity. These children will receive treatment at obesity management clinics in Calgary, Mississauga, or Ottawa. For the 24-month intervention period, one group of children (half of those enrolled) will receive FN + Usual Care; the other group will receive only Usual Care. Navigators trained in motivational interviewing and bias/stigma reduction will work with children receiving FN and their families to overcome barriers that limit their access to health services and support. Navigators will offer additional services and resources, such as parking passes for clinic visits and supportive text messages between appointments. FN is designed to support the obesity management care received by children and their families. Better access to care may help children and their families working with navigators to stay engaged and attend more treatment appointments. Ultimately, they may be more likely to succeed in managing obesity.

This retrospective observational study aims to evaluate postoperative respiratory complications (PORC) after (adeno)tonsillectomy in children with OSA. In order to increase the number of patients available for analysis, we will merge data collected at UZA with data collected at the the Department of Sleep Laboratory and Sleep Surgery at the Heim Pal National Pediatric Institute, Hungary. These colleagues performed an identical prospective data collection.

More2Sleep is a randomized, controlled, parallel trial with two groups (sleep extension vs control) including 142 school-aged children (6-12 years) who have a BMI above average, defined as age- and sex-specific BMI Z-score above zero using WHO reference standards, and habitually sleep for ≤ 9 h/night. Data will be collected before and after a 3-month sleep extension intervention, and after a 6-month follow-up (at months 0, 3, and 9). The collection of data is mainly related to the main study. However, some optional examinations will be conducted on a first come, first serve basis, consisting of substudy-I (metabolic mechanisms, n=60) and substudy-II (learning mechanisms, n=142). The primary objective is to assess the effects of sleep extension by \~45 min/night, achieved by going to bed 60-90 min earlier, on adiposity and learning ability in school-aged children who have a BMI for age and sex above average, and sleep less than recommended for their age.

The purpose of this study is to examine the effects of the (Brighter Bites (BB) intervention compared to a wait-list control group 9 months after the intervention on changes in primary child outcomes (HbA1c, and vegetable intake), on changes in secondary outcomes (household food security status, parent and child dietary behaviors, and home access/availability of fruits and vegetables (FV)), and the mediational influence of changes in food security status, parent outcomes, and home environment measures on changes in child outcomes.

The goal of this study is to 1) use magnetic resonance imaging (MRI) to evaluate the effect of nutritious foods on inflammation in the human hypothalamus of children and 2) assess the feasibility and acceptability of nutritious food feeding intervention strategies in children with overweight or obesity.

The preschool age is a crucial period of growth and an optimal time to begin to establish healthy eating and physical activity habits leading to better food and activity choices into adulthood, thereby minimizing risk for obesity-related diseases and decreasing the cardiometabolic disparities in this Indigenous population. More Outside Your Door is a multi-level, randomized, stepped-wedge intervention trial designed to reduce the disparity of childhood obesity in Yup'ik Alaska Native children by increasing the proportion of nutrient-dense traditional and traditional-like foods offered and increasing physical activity, particularly outdoor activities related to traditional Yup'ik subsistence and lifestyle practices. This 5-year intervention trial targeting 3-5 year olds is conducted in partnership with Rural Action Community Action Program Head Start programs in 12 rural Alaskan communities, where each site is assigned annually to a wedge group to receive either a community-altered culturally-tailored 8-month traditional foods and activities curriculum intervention or the standard regional Head Start program intervention.

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.

The purpose of this study is to assess the effectiveness of the produce prescription program at improving weight status and obesity-related health outcomes of participants, to examine the impacts of the program on household food insecurity and nutrition security, to examine the impacts of the program on participating adolescents' dietary behavioral outcomes, their home nutrition environment and feeding practices and to examine the impacts of the program in reducing healthcare use and associated costs

The proposed research aims to assess how well a structured intervention is intended to reduce childhood obesity. The intervention addresses food and physical activity behaviors, important determinants of obesity, by concentrating on these elements. The goal of nutritional and physical education is to raise knowledge about the negative effects of obesity and encourage healthy eating habits in children and their caregivers. These educational campaigns will be delivered primarily through schools, guaranteeing a wide audience and consistent messaging.
