Electro Encephalography and BMI The role of BETA Cortical Oscillations in Body Mass Index: A pilot study in human EEG related to BMI

Abstract

Body mass index (BMI) is a major indicator for diagnosing overweight and obesity. We aimed to explain the neural bases of BMI. Participants consisted of twenty-five undergraduate students (mean age of 21.36 years SD= 23.39) Beta band activity on electroencephalogram (EEG) was positively associated with BMI (P<0.05). Stepwise regression analysis showed that the central region of beta band could predict variances of BMI (P<0.05). In conclusion, increased beta activity on the EEG appears to be a neural markers for predicting overweight and obesity.
