Development of a sex-specific visceral fat area estimation using discrete multi-wavelength near-infrared spectroscopy measurements in Korean individuals
Authors' conclusion
This study suggested that lipid density can be used as a valid, noninvasive method to determine visceral obesity.
Study context
- Population
- Korean individuals undergoing both discrete multi-wavelength NIR spectroscopy (DMW-NIRS) measurement and abdominal computer tomography (CT) scan
- Participants
- 290 individuals
- Comparison
- DMW-NIRS-estimated visceral fat area (VFA) vs CT-measured VFA
- Outcome
- Prediction of CT-measured VFA by DMW-NIRS-estimated VFA (lipid density, age, body mass index (BMI))
Methodological detailsmodel development by multiple linear regression, sex-specific
- Model development by multiple linear regression
- Sex-specific
Performance
As reported in the abstract
Prediction of VFA by DMW-NIRS model
| Test or model | Akaike Information Criterions (AIC) | Root Mean Squared Errors (RMSE) | R2 |
|---|---|---|---|
| Female | 1199 | 29.5 | 0.544 |
| Male | 1714 | 41.3 | 0.504 |
