Front Nutr. :高咖啡消费量与脑灰质体积减少相关:孟德尔随机化研究

咖啡是全球主要消费饮料之一。一项研究表明,即使在怀孕期间,近一半的受访样本每天至少喝一杯咖啡。因此,咖啡消费对健康结果的影响是值得关注和重要的。

先前对 201 项观察性研究的荟萃分析的综述得出的结论是,喝咖啡的益处多于害处。仅发现在女性骨折和胎儿骨折上存在有害关联。至于中风,在观察性研究中也观察到有益效果。最近的一项审查发现,喝咖啡与中风风险之间存在显着的负相关。然而,痴呆症的影响尚无定论。

由于观察性研究的推论经常受到混杂因素的影响,因此一种新的两样本孟德尔随机化 MR 方法已被广泛用于评估因果关系。最近发表的使用双样本MR方法的研究表明,基因预测的咖啡摄入量可能与阿尔茨海默病和脑出血的风险增加有关,但与小血管缺血性中风的风险降低有关。

众所周知,脑小血管疾病的磁共振成像 MRI 标志物与中风、认知障碍和痴呆的风险增加有关。此外,脑容量是脑储备的替代指标之一,这一概念与认知功能和阿尔茨海默病有关。为了提供更多关于咖啡消费对脑血管疾病和认知功能影响的证据,本研究使用双样本 MR 方法进一步研究基因预测的咖啡消费对脑小血管疾病MRI标志物和脑容量的影响(图1)。

每天消耗量

基于 IVW 方法的 MR 分析表明,咖啡消耗量与灰质体积呈负相关(β = -0.37195% CI = -0.596 -0.147p = 0.001)(图2,3)。基于加权中位数法(beta = -0.352, 95% CI = -0.632 -0.072, p = 0.014)和加权模式法(beta = -0.372, 95% CI = -0.635 -0.109, p = 0.018)的MR分析显示了类似的结果。MR-PRESSO 检验未发现异常值(整体检验p值:0.726)。基于 IVWQ统计量的p值为0.652。多变量MR分析针对饮酒、低密度脂蛋白胆固醇、收缩压、2 糖尿病和吸烟逐一或全部进行调整,都显示出相似的结果(图4)。

使用来自另一项独立研究的四个SNP的复制分析证实了咖啡消费对灰质体积的影响。主要分析和复制分析都没有发现咖啡消费对其他结果的影响。

vs./无咖啡消费

基于 IVW 方法的 MR 分析表明,高咖啡消费量与灰质体积减少有关(β = -0.06195% CI = -0.109 -0.013p = 0.013)(图3)。基于 IVWQ统计量的p值为0.691。基于加权中位数法(β = -0.059, 95% CI = -0.113 -0.005, p = 0.032)的 MR 分析显示了类似的结果。然而,基于加权模式方法的影响(β = -0.044, 95% CI = -0.105 0.016, p = 0.289)减弱至不显着。在调整饮酒、收缩压和 2 型糖尿病时这种影响是显著的,但在调整低密度脂蛋白胆固醇和体重指数时影响不显着(图4)。所有其他分析均未发现高咖啡消费量对其他结果的影响。

这项包含两个样本的 MR 研究表明,每天饮用的咖啡杯数与大脑的灰质体积呈负相关。此外,与低/不喝咖啡相比,高咖啡消费与灰质体积减少有关。并未发现证据表明基因预测的咖啡消耗量与 WMH 体积、平均扩散率、分数各向异性、BMB、总脑体积、白质体积或海马体积相关。
