Objective To assess the characteristics of the community-dwelling elderly through a variety of objective evaluation and subjective evaluation tools and provide basis for cognitive function intervention in the community-dwelling elderly. Methods This study evaluated the global cognitive function, memory, executive function and attention and subjective memory feeling of 74 community-dwelling healthy elderly in Beijing. Results The study included 74 community-dwelling healthy elderly. The score of overall cognitive function was (27.28 ± 1.30) points. Less than 80% of participator did not acquire the total score in abstract, language, visual space and executive function. And only 9.8% acquired the total score in the delayed memory .The average score of the memory satisfaction questionnaire was (38.28 ± 9.40) points.In addition, there was no significant correlation between the scores of memory satisfaction of the elderly and the scores of cognitive function scale(r =0.038, P>0.05). The community elderly with normal general cognitive function also showed a relative decline in various cognitive areas, especially in delayed memory. In addition, there was no significant correlation between subjective memory perception and cognitive function scale (r=-0.116-0.157, P>0.05). Conclusions The community-dwelling elderly with normal global cognitive function have cognitive decline in some cognitive function domains. And the cognitive function training needs to be carried out in community. There is no relationship between subjective memory assessment and objective cognitive function. More researches about the relationship between subjective memory assessment and objective cognitive function should be carried out in the future.

Objective To understand the current status of dysphagia among community elderly of Dongcheng District of Beijing Municipality and to explore its related factors.Methods From May 2016 to February 2017, the International Resident Assessment Instrument Home Care (InterRAI HC) was used for data of home care needs assessment of community elderly (≥60 years old) to carry out the focused analysis of dysphagia. The evaluation result of the term "nutrition intake patterns" of InterRAI HC was taken as the standard to determine whether to be with or without dysphagia. The chi-square test and Logistic regression were used to analyze the influencing factors of dysphagia among community elderly.Results Among 229 community elderly, there were 49 cases with dysphagia with 21.4％ for the incidence. The related factors of dysphagia among community elderly included the impaired balanced capacity (OR=4.913, 95％CI: 1.772-13.618, P=0.002), yield of drinking water<1000 ml/d (OR=2.600, 95％CI: 1.253-5.396,P=0.010), ages (OR=1.048, 95％CI: 1.004-1.095,P=0.024), body mass index<18.5 kg/m2 (OR=4.576, 95％CI: 1.220-17.172,P=0.024) and history of Parkinson's disease (OR=2.505, 95％CI: 1.015-6.180,P=0.046).Conclusions The current status of dysphagia in community elderly of Dongcheng District of Beijing Municipality is worth attaching importance to. The dysphagia of the aged should be prevented, discovered and treated early by active measures such as paying close attention to related factors and effective screening.
