Allostatic Load and Biological Aging Indicators in the MIDUS National Survey
Researchers reviewed literature utilizing measures of allostatic load and biological aging to highlight the differences with respect to biological markers employed and approach toward scale construction. Opportunities where allostatic load indices might be improved by adopting analytical features of biological aging measures were outlined by researchers. Amongst other results, researchers found that all measures were significantly associated with chronological age. In conclusion, indices of allostatic load and biological age approximate similar processes when constructed with comparable biomarkers and rigor, in line with their conceptual overlap as proxies of cumulative wear and tear.
