Abstract:
To determine longitudinal risk factors for elder abuse and neglect, an established cohort of community-dwelling older adults (n = 2,812) was linked with elderly protective service records over a 9-year follow-up period. Protective services saw 184 (6.5%) individuals in the cohort for any indication, and 47 cohort members were seen for corroborated elder abuse or neglect for a sampling adjusted 9-year prevalence of 1.6% (95% CI 1.0%, 2.1%). In pooled logistic regression, age, race, poverty, functional disability, and cognitive impairment were identified as risk factors for reported elder mistreatment. Additionally, the onset of new cognitive impairment was also associated with elder abuse and neglect. Because the mechanism of elder mistreatment case-finding in this study was a social welfare system (protective services), the influence of race and poverty as risk factors is likely to be overestimated due to reporting bias.
