Incidence of Elder Abuse in a U.S. Chinese Population: Findings From the Longitudinal Cohort PINE Study.

backgroundElder abuse (EA) is a global public health issue. However, no prior longitudinal research has quantified the incidence of EA, which is critical to understand risk factors and future prevention strategies.

methodsThe study is based on a longitudinal cohort design. We followed 2,713 U.S. Chinese older adults who agreed to participate in the study within 2011 to 2015. A structured questionnaire was used to collect data regarding the 2-year incidence of EA and its subtypes. We employed multiple logistic regression analyses to examine the associations between the sociodemographic characteristics and incident EA.

resultsThe incidence of overall EA was 8.8% with 4.8% for psychological, 2.9% for financial, 0.5% for physical, 0.1% for sexual abuse, and 1.1% for caregiver neglect. Age, gender, duration of residence, language preference and health status change were associated with incident EA. Self-perceived worsened health was positively associated with overall EA (odds ratio [OR] 1.28 (1.01, 1.62). Women (OR 2.98 [1.10, 8.11]) and older individuals (OR 1.06 [1.00, 1.13]) had an increased risk of caregiver neglect. Older adults who have lived in the U.S. longer had a higher risk of financial exploitation (OR 1.02 [1.00, 1.05]). Individuals who prefer to speak Mandarin or English were more likely to experience EA (OR 2.08 [1.21, 3.58]) and sexual or physical abuse (OR 3.91 [1.01, 15.17]). No significant association was observed between education, income, marital status, number of children, country of origin, overall health, life quality, and incident EA.

conclusionThis study presents the first illustration of EA incidence in a longitudinal cohort study, the findings of which verify and challenge prior fundamental assumptions of risk factors associated with EA, and are relevant to future prevention strategies.
