内蒙古包头蒙古族、汉族轻度认知障碍患病率及危险因素的民族差异性研究

The epidemiological study of ethnic disparity in risk factors for mild cognitive impairment between Mongolia and Han population in baotou,Inner Mongolia

目的对内蒙古包头蒙古族和汉族轻度认知障碍(MCI)者的流行现状、影响因素进行对照分析,了解其民族差异性。方法采用多级整群随机抽样方式,结合集中和入户调查,对内蒙古包头的11个旗县区65岁以上的人群进行MCI的流行病学调查。结果 (1)蒙古族老年人MCI组患病率10.98%,标化患病率11.00%较汉族老年人MCI组患病率9.90%,标化患病率10.60%略高,但差异无统计学意义(P>0.05)。(2)两民族均呈现出随年龄增加MCI患病率呈逐渐增高的趋势(P<0.05)。民族间差异无统计学意义(P>0.05)。(3)同民族不同性别间比较、同性别不同民族间比较,MCI患病率之间的差异均无统计学意义(P>0.05)。(4)两民族均呈现出教育水平越低,MCI患病率越高(P<0.05)。民族间差异无统计学意义(P>0.05)。结论内蒙古包头地区蒙古族和汉族的MCI患病率均无明显性别差异,均随年龄增长及教育水平降低而增高,两民族间无差异。

Objective To investigate the differences of risk factors for mild cognitive impairment from the perspective of epidemiology Mongolia and Han population in baotou,Inner Mongolia. Methods Investigation on the mild cognitive impairment epidemiological survey of population who ≥65 years old and living in the 11 Qixian County of Baotou,Inner Mongolia by multistage random-cluster sampling combined with site questionnaires and home-visit methods.

There was significance in the rate of mild cognitive impairment in each age group（ all P〈0. 05）. there was no statistical significance between mild cognitive impairment and Han populations,P〉0. 05.（ 3） Different sex and different ethnic groups gottaked no effect on the prevalence rate of mild cognitive impairment,P〉0. 05.（ 4） According to different education degree,the prevalence rate of mild cognitive impairment increased as the education level decreased in both of ethnic groups（ P〈0. 05）.There was no significant difference between Mongolian and Han populations（ P〉0. 05）.
