- Waist-to-height ratio (WHtR) may be a better measure than BMI for identifying African-American adults at elevated risk for cardiovascular disease (CVD).
Why this matters
- Given the high rates of cardiovascular disease and metabolic risk factors in this population, it is important to develop validated, easy-to-measure indicators of CVD risk for clinical use, say researchers.
- Researchers examined data from African-American adults (n=4758), including measures of BMI, WHtR, and 5 CVD risk factors.
- C-statistics were computed and compared for BMI and WHtR to assess their associations with each risk factor.
- Funding: National Heart, Lung, and Blood Institute.
- WHtR was more strongly related than BMI to high-density lipoprotein cholesterol (C-statistic difference, −0.0129; P=.0002), triglycerides (C-statistic difference, −0.0199; P<.0001 diabetes difference p hypertension and multiple risk factors>
- The study was cross-sectional and could not show causality.
- The researchers did not examine relationships between BMI or WHtR and CVD events.
