Obesity is an epidemic that rapidly rose within the last few decades. Since 1980 obesity has doubled among adults and tripled in teenagers, contributing to a large number of health problems for overweight individuals. Obesity has been linked with reduced inhibitory control which may lead to overeating. We attempted to explore this association in students at an HBCU. Volunteers were assessed on multiple measures of obesity (BMI, hip to waist ratio, and waist circumference) and inhibitory control was measured using a go-nogo task. We predicted that that overweight or subjects with higher BMIs will have a lower inhibitory control than average weighted individuals. Our preliminary results suggest that our hypothesis was not supported; however, our current pool of subjects is low on obese participants. This project is ongoing and a broader range of participants is being recruited.
