Comprehensiveness vs Efficiency: A Cross-Sectional Analysis of the Association Between Allostatic Load and the Frailty Index Using the CLSA

The goal of this study was to investigate the associations between the frailty index (FI) and allostatic load (AL) to determine if allostatic load contains “key” biomarkers of frailty. If so, AL may offer a more concise health measure using only routine, administrative data.
