Successful Aging Cognitive Function And Related Factors

This article is to evaluate the cognitive function of successful aging by neuropsychological test through the cross-sectional study and case-control study, and to approach the related factors of cognitive function for successful aging.In order to evaluate the cognitive function, 293 retired veterans over 60 years were divided into 4 groups: 60～69 years; 70～79 years; 80～89 years; 90～99 years by cross-sectional study according to the criteria of successful aging compared with both 162 usual ages and 74 mild cognitive impairment (MCI). The results show that successful aging has better cognitive and physical function and psychology and mental health than usual aging and MCI. There are significant differences in cognitive function for different ages of successful aging, mainly in visual space skill, executive function, cognitive processing speed, memory, attention. With age increasing, the above-mentioned tends to be declined and there are differences in marriage, habitation, smoke, HBP, diabetes, coronary artery disease, hyperlipemia , COPD, tumor and chronic disease numbers. The univariate analysis between successful aging and usual aging shows that marriage, diet, somnus conduce to successful aging; smoke, HBP, diabetes, arthritis don't conduce to successful aging. The multivariate analysis shows that marriage, habitation, diet, exercise, somnus conduce to successful aging and smoke, diabetes, arthritis do not conduce to successful aging .The univariate analysis between successful aging and MCI shows that education, marriage ,diet , exercise, somnus conduce to successful aging; drink ,smoke ,HBP , diabetes, COPD ,arthritis don't conduce to successful aging .The multivariate analysis show that education, marriage ,diet ,exercise ,somnus conduce to successful aging; drink ,arthritis don't conduce to successful aging.According to the results, cognitive function has substantial heterogeneity and different crowd have respective characteristics. Age-associated losses in cognitive abilities are in different ages of successful aging, but the level of cognitive function maintains better. Extrinsic factors conduce to successful aging.
