| Summary: | Executive functions are closely related to the prefrontal cortex, and inhibitory control is an important component of executive functioning. Previous studies have found that inhibitory control continues to develop after adolescence and that obesity is associated with executive functions. However, few studies have addressed whether obesity affects the development of inhibitory control. Hence, we focused on whether inhibitory control continues to develop after adolescence in obese individuals. We used a Stroop task to measure the inhibitory control of young obese subjects, and monitored accompanying brain activation by functional near-infrared spectroscopy technology. The findings suggest that brain activation due to Stroop interference does not increase with age in obese subjects and that early prevention of executive function deficit is recommended.
