Abstract

Preobesity and obesity are among the leading causes of preventable deaths worldwide. Decreased vagal activities and high basal heart rate (BHR) observed in obesity have been reported to be associated with the future cardiovascular events. Therefore, in the present study, the difference in BHR and time domain indices (TDI) among preobese and obese subjects has been assessed. Body mass index, BHR, and TDI of heart rate variability were assessed in overweight (n = 50) and obese (n = 50) group subjects. BHR and TDI, which primarily reflect the parasympathetic cardiac modulation, were not found to be significantly different between the preobese and obese subjects. To conclude, high BHR and decreased TDI observed in the studied population suggest that there was no difference in vagal activities between the preobese and obese subjects.
