Perceived threat of Alzheimer's disease and related dementias in Chinese older adults: The role of knowledge and perceived stigma

Abstract

OBJECTIVES: This study focused on perceived threat of Alzheimer's disease and related dementias (ADRD) in Chinese older adults and investigated its associations with their perceived stigma and knowledge of ADRD. METHODS: We examined Chinese older adults' perceived threat of ADRD and its associations with perceived stigma, knowledge of ADRD, family variables and health variables. Data for this cross-sectional study were collected by student interviewers in 2016. The participants (N = 754) were recruited from two urban communities in mainland China and their ages ranged from 60 to 89 (M = 69.54, SD = 7.35). RESULTS: Hierarchical regression analyses indicated that those who are younger, have more depressive symptoms and lower levels of family cohesion are more likely to worry about ADRD. More ADRD knowledge and higher levels of perceived stigma are significantly associated with perceived threat of ADRD. Community site moderated the relationship between stigma and perceived threat of ADRD. CONCLUSIONS: Intervention or service programs need to promote ADRD knowledge and awareness in a culturally sensitive way as well as address stigma and fear toward ADRD in the older population. Future studies are needed to incorporate more cultural and environmental factors to fully understand Chinese older adults' attitudes toward and literacy of ADRD.
