目的探讨吸烟对老年人认知功能障碍的影响。方法 :采用随机整群抽样的方法从重庆市高新区、渝北区、渝中区中分别抽取了两个居委会≥ 6 0岁老年人做为调查对象 ,用简易智能量表 (MMSE)进行认知功能测定 ,采用Logistic回归多因素分析方法对测定结果进行分析。结果 :对 30 12人完成了MMSE测定 ,重庆市老年人认知功能异常率为 11.95 % ;结果显示吸烟人群中现在吸烟者对老年人认知功能障碍的危险性较大 (RR=2 .33,95 %CI=1.37～ 2 .0 2 ) ,文化程度 (RR =3.6 4 ,95 %CI =0 .88～ 2 .0 9)和年龄 (RR =3.11,95 %CI =1.2 3～ 3.75 )对老年人认知功能障碍亦有不同程度的影响。结论 :吸烟是老年人认知功能减退的重要危险因素 ,戒烟可能是降低老年人认知功能障碍发生的有效策略。
Objective To explore the effect of smoking on cognitive dysfunction in the elderly. Methods: A random cluster sampling method was used to select two elderly residents ≥60 years of age from Chongqing High-tech Zone, Yubei District, and Yuzhong District as subjects for investigation, and to use the MMSE Function determination, using Logistic regression multivariate analysis method to analyze the results. Results: MMSE was completed in 3012 people, and the abnormal rate of cognitive function in the elderly in Chongqing was 11.95%. The results showed that current smokers in smokers had a higher risk of cognitive impairment in the elderly (RR = 2.33 , 95% CI = 1.37-2.02), education level (RR = 3.6 4, 95% CI = 0.88-2.09) and age (RR = 3.11, 95% CI = 1.2 3-3.75) Cognitive dysfunction in the elderly also have varying degrees of influence. Conclusion: Smoking is an important risk factor for cognitive decline in the elderly. Smoking cessation may be an effective strategy to reduce cognitive impairment in the elderly.
