在中国人口迅速老龄化的背景下，本研究旨在研究中国65岁以上人群认知障碍患病率的趋势。我们的样本是72821名年龄在65-105岁之间的成年人，来自中国纵向健康寿命调查的七波，这是一个全国性的混合纵向队列。使用中文版的简易精神状态测验来测量CI。采用多水平回归模型检验危险因素调整后的患病率趋势。认知障碍年龄标准化患病率由1998年的11.00%上升至2008年的11.84%，2014年下降至8.88%。年龄较大、女性、受教育程度较低、居住在农村、未婚、缺乏身体和认知活动、患有中风、视力和听力障碍、日常生活障碍活动与认知障碍呈负相关。我们的研究表明，中国的认知障碍患病率呈下降趋势。然而，鉴于人口老龄化，降低患病率是否有助于减轻认知障碍负担尚不清楚。
In the context of a rapidly ageing Chinese population, this study aims to examine trends in the prevalence of cognitive impairment among people >= 65 y of age in China. Our sample is 72 821 adults aged 65-105 y from the seven waves of the Chinese Longitudinal Healthy Longevity Survey, a national mixed longitudinal cohort. The Chinese version of the Mini-Mental State Examination was used to measure CI. Risk factor-adjusted prevalence trend was examined using multilevel regression models. Age-standardized prevalence of cognitive impairment increased from 11.00% in 1998 to 11.84% in 2008 and decreased to 8.88% in 2014. Older age, female gender, less education, rural residence, not married, lack of physical and cognitive activities, suffering from stroke, vision and hearing impairment, and activities of daily living disability were negatively associated with cognitive impairment. Our study suggests a decreasing trend of cognitive impairment prevalence in China. However, whether decreasing prevalence will contribute to a reduced burden of cognitive impairment given the ageing of the population is unknown.
