ASSESSMENT OF HEART RATE VARIABILITY IN INTERRELATIONSHIP WITH EATING BEHAVIOR DISORDERS IN WOMEN WITH DIFFERENT TYPE OF OBESITY AND TYPE 2 DIABETES
Objective: to research features of vegetative regulation and their relation to eating behavior in women with different types of obesity and type 2 diabetes. Methods. 106 women were examined; survey of women included anthropometric measurements, study and calculation of heart rate variability were performed with “VNS-micro” (Neurosoft, Russia); recording of food consumption in 24hs were assessed. The types of eating disorders (ED) were detected with DEBQ. Results and discussion. Adipose tissue topography (ATT) among women is associated with vegetative regulation, as well with ED. So, the spectrum of both high-frequency (HF) and low-frequency (LF) oscillations are increased in women with gynoid type of ATT. Conversely, android type of ATT is characterized by overall decline of LF and HF oscillations with residual dominance of the sympathetic part. An increase in the relative contribution to the total power of the very low-frequency (VLF) spectrum among women has been revealed. Emotional and compulsive eating behavior disorders were prevalent in women with gynoid type of ATT, external type of ED prevailed among women with android type of ATT. Women with android type of ATT and type 2 diabetes had minimal severity of eating behavior disorders. The increase in activity of the sympathetic and parasympathetic parts of the autonomic nervous system in women with gynoid type of ATT was combined with sympathoadrenal and vagoinsular reactions, which is confirmed by a positive correlation of emotional ED with HF and LF, and there was a negative correlation of restrictive ED with LF. A negative correlation of emotional ED with VLF among women with android type ATT was detected. There are no correlation of ED indices and activity of the autonomic nervous system among women with android type of ATT and type 2 diabetes. It can be associated with manifestations of diabetic vegetative neuropathy.
