Factors affecting aging cognitive function among community-dwelling older adults

Aim The study purpose was to determine factors affecting aging cognitive function of 3,645 community-dwelling older adults in Korea. Methods The Hasegawa Dementia Scale assessed aging cognitive function, blood analyses and anthropometrics assessed cardio-metabolic risk factors, and the Geriatric Depression Scale Short Form Korean Version assessed depressive symptoms. Results Participants with poor aging cognitive function were more likely to be in the late age group (75y) and currently smoking and have a medical history of stroke, high body mass index, and high level of depressive symptoms; they were also less likely to engage in regular meals and physical activities. Conclusion Regular meals and physical activities may be primary factors for clinical assessment to identify older adults at risk for aging cognitive function. With aging, depressive symptoms and other unhealthy lifestyle behaviours should be managed to prevent cognitive function disorders.
