J Renal Nutr:饮食酸负荷过重可增加肾结石风险

2021-11-04 MedSci原创 MedSci原创

高潜在酸负荷饮食与草酸钙结石风险增加相关。

现有文献表明,饮食摄入对肾结石形成风险的影响是通过改变饮食的酸负荷。饮食依赖性净酸负荷可能通过影响钙和柠檬酸盐的排泄而增加肾结石风险。然而,迄今为止,很少有研究调查饮食酸负荷与肾结石之间的关系。因此,本研究试图评估潜在酸负荷高的饮食是否与草酸钙结石形成相关。

430名受试者(包括215名新诊断草酸钙结石患者和215名性别和年龄匹配的对照组)进行病例对照研究。在前一年中,使用经验证的食物频率问卷对饮食摄入进行评估。根据潜在肾酸负荷(PRAL)和净内源酸产生量(NEAP)估算膳食酸负荷。采用多变量logistic回归分析了膳食酸负荷指数与肾结石之间的相关性。

研究结果发现病例组的平均PRAL(标准误差)显著低于对照组,NEAP测定的高潜在酸负荷饮食与草酸钙结石形成的高风险相关,与钾和蛋白质摄入无关。前瞻性纵向研究可以证实结果的准确性。

病例组和对照组的一般特征以及饮食摄入量

总的来说,与对照组相比,这些病例更有可能患有高血压、糖尿病,并可能经常吸烟和饮用酒精饮料。相比之下,对照组的钙补充剂消耗率高于病例组。对照组摄入更多的蛋白质、钙、镁、磷、蔬菜和乳制品,但钠、水果、软饮料和SSB的摄入量较低。对照组的NEAP和PRAL得分显著高于病例组。

参与者在三个膳食酸负荷指数中的膳食摄入量

PRAL和NEAP得分越高,碳水化合物、镁、钾、维生素C、水果、蔬菜、坚果和茶的摄入量越低,但蛋白质、胆固醇、磷、钠、肉类以及全麦和精制谷物的摄入量越高。钙和乳制品的消费量在PRAL的三分位数之间没有显著差异,但在NEAP的三分位数之间呈下降趋势。较高的PRAL分数与较低的坚果摄入量相关,但在NEAP的三分位数中未发现差异。在PRAL和NEAP的三分位数中,脂肪、纤维和豆类的消耗量相似。

总的来说,在目前的病例对照研究中,研究发现由NEAP确定的高潜在酸负荷饮食与草酸钙结石风险增加相关。然而,在原始模型中,PRAL仅与草酸钙结石风险增加显著相关。此外,NEAP与草酸钙结石之间的关系与膳食蛋白质或钾摄入量无关。
