Key result
Higher ABSI is linked to reduced vagal heart rate variability regardless of baseline BMI.
Why the study?
One third of the Indian population suffers from chronic energy deficiency with increased risk of chronic diseases, and A Body Shape Index (ABSI) may better predict premature mortality risk.
Is A Body Shape Index (ABSI) associated with heart rate variability in healthy Indian males with low BMI compared to normal BMI?
Cross-Sectional (n=178)
Is A Body Shape Index (ABSI) associated with heart rate variability in healthy Indian males with low BMI compared to normal BMI?
ABSI is negatively correlated with high-frequency heart rate variability in both low and normal BMI healthy Indian males, suggesting increased cardiovascular risk with slight BMI increases in low BMI individuals.
Hypothesis-generating for ABSI-HRV links in healthy Indians; leaves open clinical utility beyond BMI or WC.
Background. One third of Indian population is said to be suffering from chronic energy deficiency (CED), with increased risk of developing chronic diseases. A new anthropometric measure called A Body Shape Index (ABSI) is said to be a better index in predicting risks for premature mortality. ABSI is also in part said to be a surrogate of visceral fat. Objective. The present study aimed to explore the association between indices of HRV (heart rate variability), BMI, WC, and ABSI in healthy Indian males with low BMI (BMI < 18.5 kg/m(2)) and to compare with normal BMI group (BMI 18.5 to 24.9 kg/m(2)). Methodology. ABSI and BMI were derived from anthropometric parameters, namely, height, weight, and waist circumference in 178 males aged 18 to 78 years. Subjects were categorized into two groups based on their BMI. Results and Conclusions. Power spectral analysis of HRV demonstrated a significant negative correlation between Log HF (high frequency) and ABSI in both low BMI [-24.2 (9.4), P < 0.05] and normal BMI group [-23.41 (10.1), P < 0.05] even after controlling for age. Thus even with slight increase in BMI among low BMI individuals, there could be a greater risk of cardiovascular morbidity and mortality.

Sharma et al. (2014) conducted a cross-sectional in Healthy (n=178). A Body Shape Index (ABSI) was evaluated on Correlation between Log HF (high frequency) heart rate variability and ABSI (p=<0.05). A Body Shape Index (ABSI) was significantly negatively correlated with Log HF heart rate variability in both low BMI (P<0.05) and normal BMI (P<0.05) healthy Indian males.
