识别可修改的风险因素,如抑郁症,低教育和糖尿病,是预防轻度认知障碍 (MCI) 的关键. 分层化这些因素有助于针对MCI风险较高的个体进行干预.
科学领域:
- 神经学 神经学
- 公共卫生 公共卫生
- 老年学是指老年学的学科.
背景情况:
- 识别轻度认知障碍 (MCI) 的危险因素对于有效的预防策略至关重要.
- 这项研究对认知不受损 (CU) 人群中可修改和不可修改的风险因素进行了分层分层,以预测MCI发病.
研究的目的:
- 在一个没有认知障碍的人群中分层11个可修改的和2个不可修改的风险因素.
- 根据这些风险因素,预测轻度认知障碍 (MCI) 的出现.
主要方法:
- 分析来自46个阿尔茨海默氏症疾病研究中心 (ADRC) 的国家阿尔茨海默氏症协调中心 (NACC) 数据 (2005-2023) 的分析.
- 评估11个可修改的风险因素 (听力损失,高血压,BMI,抑郁,视力损失,教育,高脂血症,TBI,酒,吸烟,糖尿病) 和两个不可修改的因素 (年龄,性别).
- 卡普兰-梅尔生存分析和考克斯比例危险模型用于风险分层,将因素分为低风险和高风险类别.
主要成果:
- 包括12,322个认知正常 (CU) 个体,其中2,655个转化为MCI.
- 在越来越多的危险因子四分位数 (Q2: 1.33,Q3: 1.33,Q4: 1.36) 中观察到MCI发病的危险比率 (HRs) 增加.
- 导致MCI进展的关键可修改因素包括抑郁症 (HR 1.86),低教育程度 (HR 1.30),滥用酒精 (HR 1.20) 和糖尿病 (HR 1.21). 年龄增加风险 (HR 1.06),而女性性别是保护性的 (HR 0.83).
结论:
- 风险因素分层显示MCI风险的异质性,受可修改和不可修改因素的影响.
- 抑郁症,低教育和糖尿病成为MCI进展的最重要因素.
- 为预防MCI,建议针对高风险个体的有针对性的干预措施,重点关注可改变的因素.
