A
symmetry of spectral power (SP) of frontal EEG α-activity (FAA=(SP(F4)-SP(F3)/(SP(F4)+SP(F3)) is a marker of an
individual’s emotional background and of his/her reward (RS) and punishment sensitivity (PS) in motivational processes.
A positive FAA value (FAA>0) points at greater left-hemispheric frontal cortex activity in relation to the right-brain and
speaks of a positive emotional background of the individual, his/her RS and tendency toward goal approach behavior.
Greater activity of the right-brain frontal cortex is associated with vulnerability to depression and anxiety and a PS as well as
avoidance behavior. Healthy RS subjects have enhanced mental flexibility (MF). On the other hand, it is assumed that FAA
points at the motivational orientation of behavior (approach
vs.
withdrawal) irrespectively to associated emotions. To explore
interrelationships amongst anthropometric markers of obesity, school anxiety (SA), school performance (SP), MF, emotional
eating (EE) and FAA, girls aged 9-10 without psycho-neurological diagnoses were studied: 27 with obesity and 23 with normal
weight. The obese girls had lower scours for SP. Positive link between the waist-to-hip ratio and SA was established. No links
were found among FAA, SA and BMI. However, a split correlation analysis revealed, that in the lean girls, the BMI is inversely
related with FAA (p=0.06) and FAA has a negative correlation with SA and EE. In the obese girls, to the contrary, BMI positive
liked to FAA, while FAA had an inverse correlation with FM, which perhaps speaks of RS in obese girls and of their reduced
ability to inhibit desirable but risky behavior like over-eating.
Biography
Gaukhar Datkhabayeva has completed her PhD in Human Physiology. She has worked at the Kazakh Academy of Nutrition as a Senior Researcher and has carried
out investigations on food and behavioral factors contributing to childhood obesity, as well as the influence of obesity on children’s cognitive functions, as part of a
program of prevention of pediatric obesity in school-age children in Kazakhstan. Her interests cover popularization of healthy nutrition and elaboration of effective
strategies for the promotion of healthy nutrition choices.
