摘要: 目的 将特定转移Cox模型应用于老年人阿尔茨海默病(alzheimer's disease,AD)进程研究中,探讨AD不同阶段转归的影响因素。方法 利用太原市三个社区2010年10月~2014年10月的9次随访数据,根据AD进程中的五个状态结构,包括轻度认知损害(mild cognitive impairment,MCI)、AD、失访或删失、死于AD(DEATH)和死于其他原因,拟合特定转移Cox模型,分析AD进程中各状态向其他状态转移的影响因素。结果 按照α=0.05水准,年龄(HR=0.68,95% CI:0.52~0.90)、性别(HR=2.13,95% CI:1.32~3.43)、吸烟(HR=1.93,95% CI:1.25~2.98)、高血压(HR=2.51,95% CI:1.55~4.08)、高血脂(HR=2.03,95% CI:1.25~3.30)、糖尿病(HR=1.71,95% CI:1.10~2.67)对MCI→AD转移有统计学意义;亲属痴呆情况(HR=4.11,95% CI:1.33~12.69)对MCI→DEATH转移有统计学意义;亲属痴呆情况(HR=5.88,95% CI:1.91~18.06)、高血压(HR=7.06,95% CI:1.60~31.26)对AD→DEATH转移有统计学意义。结论 根据AD进程中各状态间转移的主要影响因素,采取疾病分状态的重点防治措施,延缓疾病进展。Abstract: Objective To apply the transition-specific Cox model in Alzheimer's disease(AD) progression among the elders and to explore factors influencing each transition during different AD progression stages. Methods Data were collected from nine follow-up visits in three communities in Taiyuan City from October 2010 to October 2014. Based on the five state structures in AD progression, including mild cognitive impairment(MCI), AD, loss to follow up, die of AD(DEATH) and die of other else causes, the transition-specific Cox model was fitted to identify influencing factors for every possible transition in AD progression. Results At the significance level of 0.05, age (HR=0.68, 95% CI:0.52-0.90), sex(HR=2.13, 95% CI:1.32-3.43), smoking(HR=1.93,95% CI:1.25-2.98), hypertension(HR=2.51,95% CI:1.55-4.08), high cholesterol(HR=2.03,95% CI:1.25-3.30), and diabetes(HR=1.71,95% CI:1.10-2.67) were statistically significant for transition from MCI to AD; relatives with dementia (HR=4.11, 95% CI: 1.33-12.69)was statistically significant for transition from MCI to DEATH;relatives with dementia (HR=5.88, 95% CI: 1.91-18.06)and hypertension(HR=7.06, 95% CI:1.60-31.26) were statistically significant for transition from AD to DEATH. Conclusions Prevention measures should be taken based on the main factors of each transition in AD progression to delay the disease deterioration.
