Nutrients:老年人中,膳食纤维摄入能否降低耳鸣发病率?

2021-12-12 AlexYang MedSci原创

调查了老年人中,膳食纤维摄入能否降低耳鸣发病率。

耳鸣是耳朵或头部对声音的幻觉感知,随着年龄的增长,其发病率也会增加。已有有强有力的证据支持膳食纤维对血管健康和听力损失具有益处,因此,膳食纤维的摄入可能对预防耳鸣症状也有作用。

近期,来自澳大利亚的研究人员在《Nutrients》上发表文章,调查了老年人中,膳食纤维摄入能否降低耳鸣发病率

研究为纵向设计,确定了膳食纤维摄入量和其他碳水化合物营养变量,包括血糖指数(GI)、血糖负荷(GL)和碳水化合物总摄入量与10年内发生的耳鸣之间的关系。研究包括了来蓝山听力研究的1730名参与者(年龄≥50岁),他们均有完整的耳鸣症状和碳水化合物摄入量的基线数据,其中536名(31%)耳鸣病例因不符合纳入标准排除在进一步的发病率分析之外。使用半定量食物频率调查表收集了饮食数据,确定总膳食纤维的摄入量和来自谷物、蔬菜和水果的纤维贡献情况。使用了一个基于澳大利亚GI值的专用数据库来计算平均GI。

在基线符合标准的1194名参与者中,有222人(19%)在10年内报告了新发耳鸣状况。研究结果发现,与较高的水果纤维(>3.6克/天)和谷物纤维(>4.2克/天)摄入量相比,较低的水果纤维(≤3.6克/天)和谷物纤维(≤4.2克/天)分别与10年内耳鸣风险增加65%(HR=1.65;95%CI:1.15-2.36)和54%(HR=1.54;95%CI:1.07-2.22)显著相关。其他碳水化合物的摄入量与发生耳鸣之间的关联大多不显著。

谷物和水果纤维摄入均值与10年耳鸣发病率的相关性

综上所述,膳食纤维的摄入量与发生耳鸣之间具有一定的相关性。纤维的保护作用,特别是不溶性纤维,可能是相关性的基础,它可以通过减少心血管疾病等血管风险因素来降低耳鸣的风险。同时也需要进一步的纵向研究来评估不同类型和来源的纤维与耳鸣风险,从而证实上述研究结果。
