Why the study?
Do obesity indices correlate with altered heart rate variability at rest and in response to noise and standing in healthy adults?
Population
41 healthy persons ranging in age from 20 to 65 years, including normal and obese individuals
Comparison
Exposure to stress stimuli (noise and standing) vs Normal weight group
Design
Cross-sectional

Obesity may impair autonomic balance; hypothesis-generating and requires longitudinal studies to assess causality.
Do obesity indices correlate with altered heart rate variability at rest and in response to noise and standing in healthy adults?
Obesity indices are negatively correlated with heart rate variability parameters at rest, suggesting that obesity alters cardiac autonomic nervous responses.
