(1)背景资料：我们建议对居住在社区的50岁以上成年人的认知障碍患病率和发病率进行全球评估。(2)方法：于2019年1月使用MEDLINE/PubMed进行系统检索。如果文章涉及认知功能障碍、患病率、发病率、老年人、人口或社区研究，则选择这些文章。分析，汇总不同的方法学特征，进行。(3)结果：患病率（80项研究）范围为5.1%-41%，中位数为19.0%（第25百分位数= 12.0%;第75百分位数= 24.90%）。发生率（11项研究）范围为22 - 76.8/1000人-年，中位数为53.97/1000人-年（第25百分位数= 39.0;第75百分位数= 68.19）。除入选年龄外，未发现统计学显著性影响。(4)结论：我们建议，同质化和澄清的定义是什么构成认知障碍是必不可少的，以完善流行病学的理解，这一实体。本综述的结果强调了坚持认知测试的标准化截止分数以促进研究可比性的重要性。
(1) Background: We proposed to review worldwide estimates of cognitive impairment prevalence and incidence in adults older than 50 years of age living in the community. (2) Methods: Systematic searches were performed in January 2019 using MEDLINE/PubMed. Articles were selected if they referred to cognitive impairment, prevalence, incidence, elders, and population or community-based studies. Analysis, aggregated by different methodologic features, was performed. (3) Results: Prevalence (80 studies) ranged between 5.1% and 41% with a median of 19.0% (25th percentile = 12.0%; 75th percentile = 24.90%). Incidence (11 studies) ranged from 22 to 76.8 per 1000 person-years with a median of 53.97 per 1000 person-years (25th percentile = 39.0; 75th percentile = 68.19). No statistically significant effects were found except for inclusion age. (4) Conclusion: We propose that the homogenization and clarification of the definition of what constitutes cognitive impairment are essential to refine the epidemiological understanding of this entity. The results of this review reinforce the importance of adherence to standardized cut-off scores for cognitive tests to promote study comparability.
