| 目的 了解北京市社区老年人痴呆患病率和死亡率及老年综合征（GS）对其影响。方法 2013-2015年采用多阶段抽样的方法确定调查地区和研究对象，对抽取的≥65岁老年人进行横断面调查，采用简易智力状态检查量表（MMSE）中国修订版对老年人认知功能进行初筛，随后对MMSE低分者进行神经精神科检查。收集所有调查对象GS患病情况，并在调查后收集死亡数据（截至2019年12月31日）。以2010年第六次全国人口普查北京市数据对痴呆患病率进行标化。采用logistic回归模型分析GS与痴呆及各亚型痴呆患病风险的关系，采用Cox比例风险回归模型估计各亚型痴呆老年人的死亡风险比（HR）及其95%CI。结果 2013-2015年共有2 935名老年人完成痴呆调查和诊断，其中167名诊断为痴呆。痴呆标化患病率为5.9%（95%CI：5.0%~17.4%），阿尔茨海默病（AD）和血管性痴呆（VaD）分别占总痴呆患者人数的58.7%和28.1%。增龄、低文化程度、尿失禁、跌倒是AD的危险因素，日常生活活动能力完全丧失、高血压、脑卒中是VaD的危险因素，居住在农村与AD和VaD患病风险增加均相关。经过5.44人年随访（中位随访时间），共有399名死亡。AD和VaD老年人5年死亡风险是非痴呆老年人的2.87（95%CI：1.92~4.17）倍和4.93（95%CI：3.23~7.53）倍；在控制社会学人口因素、GS和心脑血管危险因素后，AD老年人死亡风险与非痴呆老年人无明显差异（HR=1.32，95%CI：0.89~1.97），VaD老年人的死亡风险是非痴呆老年人的2.46（95%CI：1.49~4.05）倍。结论 北京市痴呆患病率随人口老龄化而明显增加，特别是AD；AD和VaD患病和死亡风险均与GS相关，在痴呆防治中需要关注GS的管理。 |

| Objective To investigate the prevalence and mortality of dementia and assess the impact of geriatric syndromes (GS) on the risk for dementia and death in elderly population in Beijing. Methods A cross-sectional survey was conducted in the elderly population aged ≥65 years and selected by a multi-stage sampling in Beijing during 2013-2015. Cognitive function was screened using the Chinese Revised Version of the Mini-Mental State Examination (MMSE). Then, neurological examination and psychiatric assessment were performed for those with the MMSE score lower than the cut-off value. The information about GS prevalence was also collected. The study also collected death records for all individuals from baseline until December 31, 2019. Based on the age and gender distribution from Beijing data of the 2010 Sixth National Population Census, the dementia prevalence in the study population was directly standardized. Logistic regression analysis was used to evaluate the association of different forms of dementia with GS, and Cox proportional hazards regression model was used to estimate the hazard ratio (HR) and 95%CI of death. Results During 2013-2015, a total of 2 935 individuals completed dementia assessments, of which 167 were diagnosed with dementia. The standardized prevalence of dementia was 5.9% (95%CI: 5.0%-17.4%). The individuals with Alzheimer's disease (AD) and vascular dementia (VaD) accounted for 58.7% and 28.1% of total individuals with dementia, respectively. Aging, lower education level, urinary incontinence, and fall were risk factors for AD, while disability of activity of daily life dependence, hypertension, and stroke were found to be risk factors for VaD. After a median follow-up of 5.44 person-years, 399 deaths were recorded. The 5-year mortality risk was 2.87 (95%CI: 1.92-4.17) times and 4.93 (95%CI: 3.23-7.53) times higher for the elderly individuals with AD and VaD, respectively, compared to non-demented individuals. After adjusting for demographic, GS, and cardiovascular risk factors, the mortality risk in the elderly individuals with AD showed no significant difference compared with non-demented individuals (HR=1.32, 95%CI: 0.89-1.97), while the mortality risk in those with VaD was 2.46 (95%CI: 1.49-4.05) times higher than that in non-demented individuals. Conclusions The prevalence of dementia in Beijing increased significantly in the context of population aging, especially the prevalence of AD. The presence of GS increased the risks for AD and VaD, as well as the risk for death. Close attention needs to be paid to GS management in dementia prevention in elderly population. |
