摘要：

目的 了解重庆市部分敬老院老年人吸烟和认知功能的基本现状，探讨吸烟对老年人认知功能的影响。方法 采用分层随机抽样的方法，根据相应的纳入、排除标准，从重庆市11家各型敬老院中抽取≥60岁老年人230名，使用自编老年人营养健康情况调查表和简易智能状态量表(MMSE)进行调查，采用χ2检验和Fisher确切概率法对结果进行分析。结果 对符合条件的230名老年人完成了MMSE测定，有认知功能异常率的为151人（65.65%）；结果显示，现在是否吸烟与认知功能障碍具有统计学意义（χ2=12.897 7，P=0.000 3），而过去吸烟与认知功能障碍差异无统计学意义（χ2=1.330 0，P=0.248 8）；现在吸烟时间长短，与老年人认知功能异常具有统计学意义(χ2=16.887 9,P<0.000 1）。结论 现在吸烟是老年人认知状况减退的危险因素，并且吸烟时间越长危险性越大，尽早的戒烟可能是降低老年人认知功能发生的有效措施。

Abstract:

Objective To investigate the smoking and cognitive function of elderly people in some geracomiums of Chongqing city and to explore the effects of smoking on the cognitive function. Methods The stratified random sampling method was adopted. According to the inclusion and exclusion criteria, 230 old people (age≥60 years) from 11 geracomiums of Chongqing city were selected and surveyed by the nutrition health questionnaire for old people and Minimum Mental State Examination (MMSE). The results were analyzed by the χ2 test and Fisher exact probability method. Results MMSE was performed for 230 qualified old people. Among them, 151 people (65.65%) were with the cognitive impairment. The relationship of current smoking and cognitive impairment was statistically significant (χ2=12.897 7，P=0.000 3), while the relationship of past smoking and cognitive impairment was no statistically significant (χ2=1.330 0, P=0.248 8). The relationship of the period of current smoking and the cognitive impairment was statistically significant (χ2=16.887 9, P<0.000 1). Conclusion Current smoking is a risk factor of cognitive impairment of old people. The risk increases with the period of smoking. Quitting smoking is an effective measure to decrease the incidence of cognitive impairment.
