Acculturation and functional impairment among older Chinese and Vietnamese in San Diego County, California.

Level of acculturation and the relationship to functional impairment was examined among a group of Chinese (n = 50) and Vietnamese (n = 50) 45 years and older in San Diego County, California. Prevalence of functional impairment and level of acculturation, one-way analysis of variance and Pearson correlations were utilized to examine differences between ethnicity, gender and age groups, as well as significant relationships between various dimensions of impairment and levels of acculturation. Findings indicated that lack of English language skills and lack of use and exposure to English were associated with social and economic resource impairment, mental and physical health impairment, and ADL impairment, as measured by a modified OARS instrument. Data suggested that the visibility and extensiveness of the Vietnamese community may serve to buffer the negative effects associated with the acculturation process for the Vietnamese.
