Modality of physical exercise and cognitive function in Hong Kong older Chinese community.

ABSTRACT

OBJECTIVE: We reported the association between modality of Physical Exercise and cognitive function in 782 older Chinese adults assessed in the second phase of a population survey for dementia in Hong Kong. METHODS: Profiles of physical exercise was measured by a questionnaire (no exercise, stretching, aerobic and mind-body exercise). Cognitive Assessments included the CMMSE, ADAS-Cog, and Category Verbal Fluency Test (CVFT). RESULTS: The aerobic and mind body exercise groups with longer exercise habits (>5 years) had higher scores in most cognitive tests (Kruskal Wallis tests, p < 0.01). Beneficial effects were more significant in the young old group from 65- 75 years. CONCLUSIONS: Possible age related specific effects of aerobic and mind body exercise on cognitive reserve are worthy of further exploration.
