Elder abuse and mortality: the role of psychological and social wellbeing.
BACKGROUND
Elder abuse is a pervasive human right and public health issue.


OBJECTIVE
We aimed to examine the mortality associated with elder abuse across levels of psychological and social factors.


METHODS
The Chicago Health and Aging Project (CHAP) is a prospective population-based cohort study that began in 1993. A subset of these participants enrolled between 1993 and 2005 had elder abuse reported to social services agencies (n = 113). Mortality was ascertained during follow-up and with the National Death Index. Psychosocial factors (depression, social network and social engagement) were assessed during the CHAP interview. Cox proportional hazard models were used to assess the mortality of elder abuse across levels of psychosocial factors using time-varying covariate analyses.


RESULTS
The median follow-up time for the cohort (n = 7,841) was 7.6 years (interquartile range 3.8-12.4 years). In multivariate analyses, those with highest (hazard ratio (HR) 2.60, 95% CI 1.58-4.28) and middle levels (HR 2.18, 95% CI 1.19-3.99) of depressive symptoms had an increased mortality risk associated with elder abuse. For social network, those with lowest (HR 2.50, 95% CI 1.62-3.87) and middle levels (HR 2.65, 95% CI 1.52-4.60) of social network had increased mortality risk associated with elder abuse. For social engagement, those with lowest (HR 2.32, 95% CI 1.47-3.68) and middle levels (HR 2.59, 95% CI 1.65-5.45) of social engagement had increased mortality risk associated with elder abuse. Among those with lowest levels of depressive symptoms, highest levels of social network and social engagement, there was no significant effect of reported or confirmed elder abuse on mortality risk.


CONCLUSIONS
Mortality risk associated with elder abuse was most prominent among those with higher levels of depressive symptoms and lower levels of social network and social engagement.
