JAMA Neurol:肌萎缩侧索硬化患者发病前,新陈代谢或已改变

2015-08-27 徐媛媛 MedSci原创

由于高脂肪饮食会增加肌萎缩性脊髓侧索硬化症(ALS)患病风险,在ALS发病前,饮食摄入量与ALS发病风险之间的关系可能让我们更加了解ALS的病理生理过程。。本研究旨在确定发病前的饮食摄入量与ALS发病风险之间的关系。从2006年1月1日到2011年9月30日在荷兰进行以人群为基础的病例对照研究。研究人员通过食物频率问卷调查(199项)来评估发病前饮食摄入与散发性ALS风险之间的关系。研究人员收纳了

由于高脂肪饮食会增加肌萎缩性脊髓侧索硬化症(ALS)患病风险,在ALS发病前,饮食摄入量与ALS发病风险之间的关系可能让我们更加了解ALS的病理生理过程。。本研究旨在确定发病前的饮食摄入量与ALS发病风险之间的关系。

从2006年1月1日到2011年9月30日在荷兰进行以人群为基础的病例对照研究。研究人员通过食物频率问卷调查(199项)来评估发病前饮食摄入与散发性ALS风险之间的关系。研究人员收纳了986名患者,这些患者都是新近诊断的可能、很可能或确诊的ALS的。在986名患者中,其中674名患者返回完整的调查问卷。对照组有2093名年龄和性别与之相匹配的无ALS的人群。

研究结果,与对照组相比,ALS患者症状前摄入的总热量明显升高(平均2258 vs 2119 kcal/day; P <0.01),但是发生症状前BMI却显著低于对照者(25.7 vs 26.0; P=0.02)。发病前营养物质消耗与ALS风险优势比(95% CI),总脂肪的摄入量为1.14(1.07 - -1.23;P < .001),饱和脂肪为1.43(1.25 - -1.64;P < .001),反式脂肪酸为1.03(1.01 - -1.05;P < .001)和胆固醇为1.08(1.05 - -1.12;P < .001)与ALS发病风险增加相关联,摄入较多酒精0.91(0.84 - -0.99;P = 0.03)与ALS的风险下降有相关性。这些关联与总能量、年龄、性别、BMI、教育程度、吸烟和终身体育锻炼无关。没有发现显著的饮食摄入量和生存之间的关联。

以上研究结果提示,肌萎缩侧索硬化(ALS)患者在发病症状出现之前就已出现新陈代谢改变。发病前摄入较高的总脂肪、饱和脂肪、反式脂肪酸和胆固醇与ALS风险增加相关联,而摄入较多的酒精与ALS风险下降具有相关性。
