Red cell distribution width (RDW), a novel biomarker, and anthropometric measures have been shown to be independent predictors of cardiovascular (CVD) events. We sought to explore the effect of anthropometric measures on predictive value of RDW for CVD, coronary heart disease (CHD) and all-cause mortality in a nationally representative population free of clinical CVD and diabetes mellitus (DM) at baseline.
The study cohort included 14,005 adults enrolled as a part of the Third National Health and Nutrition Examination Survey (NHANES). Formal statistical analyses of the interaction term between anthropometric measures and RDW for outcomes were performed followed by stratified multivariate Cox proportional hazard analyses.
A significant interaction between RDW and anthropometric measures with higher hazard ratios for mortality, in particular CVD mortality, was observed among those with abnormal measures of anthropometry.
