Body roundness index ( body roundness index (BRI) ) and obesity‐related anthropometrics: Relationship to visceral adiposity, insulin sensitivity index and cardiometabolic risk
Authors' conclusion
BRI, while strongly correlated with visceral adiposity and ISI, does not outperform simpler measures like WC or percentage body fat. Bioimpedance, being non-invasive, demonstrates utility in assessing visceral adiposity in clinical settings. Ethnic-specific thresholds for BRI and WC may improve precision in obesity-related health assessments.
Study context
- Population
- Young, healthy, normoglycemic adult males of multiethnic cohorts in Asia; mean ages 28.4 ± 6.0, 27.6 ± 5.1 and 26.0 ± 4.8 years
- Participants
- 101 / 85 / 82
- Exposure
- BRI vs body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR) and % body fat as measures of visceral adiposity and insulin sensitivity
- Chinesen = 101
- Malayn = 85
- South Asiann = 82
- Outcome
- Correlation of BRI with MRI-measured VAT, SAT and clamp ISI
Methodological detailsmultiethnic
- Multiethnic
Main finding
As reported in the abstract
BRI correlation with VAT (r)
0.72
BRI correlation with SAT (r)
0.85
BRI correlation with insulin sensitivity index (ISI) (r)
−0.51
Observational data: associations, not effects.
Further findings
BRI by ethnic group
- BRI showed consistent results across ethnic groups; highest VAT correlation in Malays (r)
- 0.76
Other measures
- % body fat by bioimpedance as effective as Magnetic Resonance Imaging (MRI) in predicting adiposity
- WHR had the weakest correlation with VAT
