| Objective: Mild cognitive impairment is an early performance of Alzheimer's disease, and it has a high possibility in changing to dementia.Therefore, identifying MCI patients early and finding effective intervention approaches can delay or even prevent the occurrence of dementia. The recent study indicated that life style was related to changes of cognitive functions. In order to study the correlation between cognitive level and life style in MIC patients, this study enrolled a total of 300 MCI patients whose age were above 60 years old for demography and life-style concerned questionnaire investigation, and achieved data was processed statistically for exploratory factor analysis and for constructing structural equation model, descripting features of life style in community aged MCI patients in Wuhan City and constructing the structural equation model for the relation between life style and cognition in MCI patients. The study will provide reference for establishment of systemic and comprehensive nursing intervention pattern for aged MCI patients in the future, slowing down cognitive function decline in MCI patients and improving their qualities of life styles.Method: The method of cluster sampling was adopted. A total of 10 representative communities were selected, including communities in central urban area of three Wuhan towns(Wuchagn, Hankou and Hanyang), suburb communities and rural-urban communities; diagnostic criteria concerning mild cognitive impairment in Tian Jinzhou-edited Chinese Guidelines for the Diagnosis and Treatment of Alzheimer's Disease and Other Dementias(2012) was taken as reference; Mini-Mental State Examination(MMSE), Montreal Cognitive Assessment(Mo CA), Activity of Daily Living Scale(ADL) and other assessments concerning cognitive function were adopted to screen out a total of 300 mild cognitive impairment patients, whose ages were above 60 years old and in which general information and life-style concerned questionnaire investigations were conducted. SPSS 18.0 software was used for descriptive statistics, explorative factor analysis, reliability test, T-test and F test, and Amos21.0 software was used to construct structure equation models.Results:1.Explore factor analysis extracted six factors: liquor and tobacco consumption behavior, heavy activity, mild activity, walking, sleep, tea-drinking, together explain the total variance of the 82.288% original variables.2.Male patients with MCI in mild activity score was significantly lower than that of females(t=-2.380,P<0.05),MCI patients of different ages and different occupations in heavy activities exist significant difference(P<0.05). Professional and technical personnel in the heavy activity score was significantly higher than that in other occupations(F=6.434,P<0.05,?2=0.103; MCI patients with 80 years of age and older in heavy activity score was significantly higher than that of 61-80 years(F=3.665,P<0.05, ?2=0.037).3.The different educational level of elderly patients with MCI at tea-drinking exist the significant differences(P<0.05),the college degree and above and senior high school / technical school/ College group liquor behavior is significantly higher than that in primary school, junior high school group(F=3.058,P<0.05, ?2=0.041).4.Aged MCI patients with different dwelling states in liquor and tobacco consumption behavior, mild activity, heavy activity,walking, sleep and tea-drinking was not significant on the difference(P>0.05)5.Married and divorced, solitary senile MCI patients in liquor and tobacco consumption behavior, mild activity, heavy activity, walk, sleep and tea-drinking does not exist significant difference(P>0.05).6.The Structural equation model verified the results show that it exists the significant correlation between the lifestyle of the MCI patients and the cognitive level of the MCI patients, the main factors are liquor and tobacco consumption behavior(direct effect 0.124,P<0.05), mild activity(direct effect 0.121,P<0.05), sleep(direct effect of 0.337,P<0.05) and tea-drinking(direct effect of 0.204,P<0.05), together explaining the cognitive level of 57.3% of the variance.Conclusion:1.The amount of heavy activities was higher in daily lives of senior patients aged 80 years old or above, which might be related to body function degradation in senile ones with advanced ages and indicated that the advanced ages tended to be tired, intervention concerning physical training in the advanced ages should be conducted early to avoid to miss the optimum opportunity.2.The life style in divorced or solitary senile MCI patients showed no significant difference, indicating that higher risk of cognitive impairment in this group might be caused by psychological trauma factors; therefore, nursing intervention for this group should emphasize the psychological nursing.3.Liquor and tobacco consumption behaviors, mild activities, sleep and tea-drinking these four kinds of lifestyle factors have protective effect on cognitive function. When constructing a corresponding model of cognition protection-oriented nursing intervention, liquor and tobacco consumption behaviors, mild activities, sleep and tea-drinking factors should be concerned with especially emphasis on guarantee of night sleep and formation of tea-drinking habit in the aged; in order to achieve favorable intervention outcomes.4.Although it was suggested that smoking protected cognitive functions, smoking was not the best choice for interventions as it caused heart, brain, lung and other injuries. Administration of nicotine by instillation, oral, skin permeation and other approaches could be adopted to promote cognitive functions. |
