Background: The prevention of cognitive impairment is a crucial public health issue, and leisure activities have been studied as the strategy of the cognitive preservation. The aim of the study was to explore the possible relationship between social activity and cognitive function among community-dwelling Chinese elderly in two big cities of Southern China.
Participants and methods: Altogether, 557 nondemented older adults aged 60 years and older (73.4±6.5 years) were recruited in the social centers in Hong Kong and Guangzhou. A leisure activity questionnaire was used to measure the social activity participation. Cognitive function was examined using a neuropsychological battery. The association between social activity and cognitive function was analyzed using the multiple linear regression analysis.
Results: Social activities had a weak relationship with cognitive performance when measured in terms of overall participation. Attending an interest class had significant association with the Cantonese version of Mini Mental State Examination, the word list learning test, the delayed recall test, and the trail making test. Religious activity showed significant association with the word list learning test and the digit vigilance test. Singing had significant association with the Category Verbal Fluency Test (CVFT) and the trail making test.
Conclusion: Some individual social activity items may be associated with better cognitive function among the community Chinese elderly independently of other factors.
