The Impact of Food Advertisements on Brain Response and Eating Behavior in Children
11 januari 2021 uppdaterad av: Kathleen Loralee Keller, Penn State University
The purpose of this project is to examine the impact that television food advertisements have on brain responses and eating behavior in children.
Food advertisements enhance children's liking and intake of foods that tend to be high in energy content and low in nutritional value.
Although several studies have measured the differences in children's food intake after watching advertisements, none have shown the brain mechanisms associated with this change in behavior.
In order to clarify the relationship between food advertising and eating behavior, the investigators have assembled a team with expertise in functional imaging, eating behaviors, and clinical pediatric research.
First, the investigators will observe the differences in children's eating behaviors after being exposed to food commercials or non-food commercials.
Second, the investigators will measure the difference in child brain response to high and low energy foods after being exposed to food commercials or non-food commercials.
These data will allow us to identify which areas of the brain are specifically affected by exposure to food commercials and correlate activity in these areas with children's measured food intake in the laboratory.
Children ages 7-9 will participate in this 5-visit study which will be completed over the course of 12 months.
Understanding how food advertisements impact children's brain responses and subsequent eating behaviors will have implications for understanding why some children respond differently to these cues than others.
These outcomes may also inform the development of more effective programs and policies to prevent childhood obesity.
