JAMA Intern Med:九因素增加男性早发型痴呆风险

2013-09-04 郝帅 中国医学论坛报

一项瑞典研究显示,大部分男性早发型痴呆(YOD)可归因于9个独立危险因素。这些危险因素间呈倍增关系,且大部分具有潜在可变性,并可追溯至患者的青少年时期。该研究8月12日在线发表于《美国医学会杂志·内科学》(JAMA Intern Med)。

研究队列来自于1969年1月1日至1979年12月31日瑞典军事服务征兵登记,共纳入逾48万名应征入伍的男性,平均年龄18岁。在征兵过程中,对潜在危险因素(如认知功能及不同生理特征)进行评估。研究者同时通过国家注册联网,收集其他危险因素。

结果为,随访时间中位数为37年,共诊断YOD487例,年龄中位数为54岁。在多变量Cox回归分析中,具有显著性(P<0.05)的危险因素包括酒精中毒、脑卒中、使用抗精神病药物、抑郁、父亲患有痴呆、除酒精外的药物中毒、征兵中检测出认知功能低和征兵中检测身高较低。人群归因风险(PAR)与上述9个危险因素之间相关性为68%。随访研究显示,具有上述至少2个危险因素及整体认知功能处于最低1/3区间的男性,其发生YOD的风险增加20倍。
