Beyond body mass index (BMI): the predictive value of body roundness index for cardiovascular mortality and related disparities: a national cohort study of US adults
Main finding · CV mortalityResult — go to the resultHazard ratio 1.54 95% CI 1.13–2.08Authors' conclusion
Higher BRI is independently associated with increased cardiovascular mortality, particularly among middle aged adults and those with normal BMI, underscoring its potential as a practical, noninvasive tool for cardiovascular risk stratification.

Main finding
As reported in the abstract
Hazard ratio
1.54
95% CI 1.13–2.08
P = 0.006
Q5vs Q3
HR 1.54 (95% CI 1.13–2.08); P = 0.006
Observational data: associations, not effects.
Secondary outcomes
CV mortality, normal BMI (subgroup)
- Risk remained high even among those with normal BMI
Shape of BRI–CV mortality association (restricted cubic spline (RCS))
- Modest U-shaped association
CV mortality by age and education (subgroups)
- Stronger effects among middle-aged adults (45-64 years) and those with higher educational attainment
