Summary
A portable Omron bioelectrical impedance analysis (BIA) device accurately estimates total body fat in adults with obesity and diabetes, similar to a clinical standard. However, visceral fat measurements showed variability in certain groups, indicating its best use for general monitoring.
Area of Science:
- Obesity research
- Metabolic disorders
- Medical device validation
Background:
- Rising obesity rates in India necessitate accurate body fat assessment for risk stratification and treatment monitoring.
- Bioelectrical impedance analysis (BIA) offers a practical alternative to costly imaging methods like DEXA or MRI.
- Portable BIA devices present an accessible solution, but require validation against established standards like the InBody 770.
Purpose of the Study:
- To validate the accuracy of a portable Omron HBF-702T BIA device against the clinical reference standard InBody 770.
- To assess the agreement between the two devices for measuring total body fat and visceral fat in an adult population with obesity and diabetes.
- To evaluate performance across different subgroups, including gender and body mass index (BMI).
Main Methods:
- A cross-sectional study involving 343 adults at a specialized clinic in New Delhi.
- Simultaneous measurement of body and visceral fat using the portable Omron HBF-702T and the InBody 770.
- Statistical analysis using Pearson correlation coefficients and Bland-Altman plots, with subgroup analyses.
Main Results:
- The Omron HBF-702T showed excellent correlation (r=0.91) with the InBody 770 for total body fat percentage.
- High correlations for total body fat were consistent in males (r=0.87) and individuals with BMI ≥30 (r=0.90).
- Visceral fat estimation by Omron correlated well overall (r=0.73) but showed weaker performance in females (r=0.68) and those with BMI <30 (r=0.40).
Conclusions:
- The portable Omron HBF-702T reliably estimates total body fat in individuals with obesity and diabetes, comparable to the InBody 770.
- Visceral fat estimation accuracy varies in specific subgroups, particularly females and individuals with lower BMI.
- The Omron device is a practical and affordable tool for routine monitoring of body composition in clinical and home settings.
