NEJM:非糖尿病患者血糖升高同样增加痴呆的发病风险

2013-08-09 NEJM dxy

糖尿病是痴呆的危险因素之一。对于非糖尿病患者来说,高血糖水平对痴呆的风险影响尚不明确。来自美国的Paul K. Crane等学者研究了糖尿病患者及非糖尿病患者的平均血糖水平与痴呆的相关性,发表在2013年8月8日的NEJM杂志上,结果显示:高血糖水平是痴呆的危险因素之一,这种危险性即使在非糖尿病人群中也存在。【原文下载】 该研究共纳入2067例参与者,搜集了35264份血糖检测标本和1020

该研究共纳入2067例参与者,搜集了35264份血糖检测标本和10208份糖化血红蛋白标本。入组人群初始时均无痴呆表现,通过随访观察血糖水平与痴呆风险的相关性。参与人群来源于ACTS研究,包括839例男性和1228例女性患者,平均年龄为76岁;232例糖尿病患者,1835例非糖尿病患者。采用Cox回归模型,根据血糖状态进行分层,对年龄、性别、研究队列、教育水平、锻炼情况、血压、心脑血管疾病、心房颤动、吸烟、高血压的治疗等因素进行调整分析。

在平均随访6.8年后,524例观察者发展为痴呆(其中74例糖尿病患者和450例非糖尿病患者)。在非糖尿病者中,在初始5年内的平均高血糖水平与痴呆风险增加相关;平均血糖水平115mg/dL(6.4mmol/L)与平均血糖水平100mg/dL(5.5mmol/L)相比,调整后痴呆危险比(OR)为1.18。糖尿病的患者中,高血糖同样与痴呆风险增加相关;平均血糖水平190mg/dL(10.5mmol/L)与160mg/dL(8.9mmol/L)相比,调整后的危险比为1.40。

该研究结果显示,高血糖水平是痴呆的危险因素之一,这种危险性即使在没有糖尿病的人群中也存在。
