Heart rate variability during deep breathing as an index of autonomic dysfunction in obese medical students -A cross sectional study

Abstract

Background: Obesity, a global health concern, exerts significant cardiovascular implications. 
Autonomic dysfunction is a recognized risk factor for cardiovascular diseases. This study 
explores the potential of heart rate variability (HRV) during deep breathing as an index for 
assessing autonomic dysfunction in obese medical students. 
Materials and Methods: A cross-sectional study was conducted on medical students with 
obesity (n=150). Demographic information, anthropometric measurements, and HRV data were 
collected. Participants also completed questionnaires regarding stress, physical activity, and diet. 
Correlations between BMI and HRV parameters, as well as the influence of lifestyle factors on 
HRV, were analyzed.
