Understanding Children's Resilience to Food Advertising
This observational study aims to understand why some children are less affected by food advertising, which often encourages overeating and can lead to obesity. Researchers are looking for children aged 7 to 9 years old who are generally healthy and do not have certain medical conditions or allergies to study foods. The study will look at how children's brains react to food and toy commercials using fMRI (functional magnetic resonance imaging, a type of brain scan), and how much food they eat after not watching commercials. The goal is to identify specific brain, thinking, and behavior patterns that help children resist overeating caused by food ads, especially in families with a higher risk of obesity. The study plans to enroll 200 children, but its current status is unclear.
- Study design
- This is an observational study, meaning researchers will watch and collect information without giving any specific treatments. It plans to enroll 200 participants.
- What's involved
- Not specified in the trial record.
- Compensation
- Not stated in the trial record.
- Follow-up
- The primary endpoints, such as fMRI responses and food intake, are measured at baseline (the start of the study).

- Video recording of meal and EAH snack buffetbaseline
A digital recording of the Child eating the Test Meal and the EAH snack buffet will be saved. We have developed a behavior coding technique to count specific behaviors while the child eats. We will also be transcribing the audio.
