The Social Vulnerability Index: Assessing Replicability in Predicting Mortality Over 27 Years

With advancing age, the impact of social and living conditions is still greater.1, 2A decade ago Andrew et al operationalized social vulnerability according to a deficit accumulation approach, and they showed that greater social vulnerability is strongly associated with increased mortality in older adults.3 Beyond the Canadian context where the Social Vulnerability Index (SVI) has been computed, its predictive value has been replicated in only two studies.4, 5 The present study takes advantage of the PAQUID survey involving 27 years of follow‐up to assess the replicability of the SVI by confirming its association with mortality in the context of a French population‐based study.
