ABSTRACT
Objective To explore the main influence factors of ederly people's cognitive function and provide the countermeasures. Methods A cross-sectional study was performed in the elderly volunteers who were sampled from halves of the counties of 22 provinces in China.Modified minimental state examination(MMSE)scale was adopted to investigate the 6819 Chinese elderly people who were investigated in the Chinese elderly health questionnaire in 2002.Simple Chi-square test and multiple logistic regressions were applied in the analysis. Results The results showed that the perfect rate of cognition function was 85.0%in male,and 80.43%in female.The rate was 97.7%in people at age of 60-69 years,94.8%,70-79 years,85.0%,80-89 years,71.11%,90-99 years,55.7%,100-111 years,94.8%.There existed significant cognitive function differences in gender,age,education,born place,marital status,1iving status,smoking history,drinking history,physical exercise,self-satisfaction with life,affective state and healthy status(all P＜0.01).Non-conditional logistic regression analysis showed that influence factors of cognitive function of the elderly were age,education level,marital status,physical exercise and optimistic state. Conclusions The risk factors for cognitive function are aging and widowhood.Higher education,regular physical exercise,optimistic state are protective factors for cognitive function.
