摘要
背景:慢性肾脏疾病(CKD)是一个日益严重的全球公共卫生问题。体育锻炼减轻了几种与肾脏相关的病理生理途径,但其对肾功能的影响仍未得到充分探讨。我们研究了体育锻炼对老年人肾功能保护的剂量反应效应。方法:对2012年至2018年在挪威特隆赫姆进行的一项为期5年的开放标签、随机、平行组临床试验“Generation 100 Study”进行回顾性分析。所有70-77岁的居民被邀请(n=6,966)。主要排除标准为痴呆;严重的、未控制的心血管疾病或高血压;或妨碍运动的条件。对照组(n=385)接受国家体育活动建议信息。干预组接受有监督的中等强度连续训练(峰值心率的70%),每次50分钟(n=380),每周2次,持续5年;或接受高强度间歇训练(峰值心率的90%),每次4分钟× 4 (n=391),每周2次,持续5年。主要结局是基于胱抑素c的eGFR快速下降(每年0.5 ml /min/1.73m2)。结果:共有1156名参与者被随机分组,中位年龄(四分位间距)为72(3)岁,eGFR为95 (20)mL/min/1.73 m2。对照组、中等强度组和高强度组的摄氧量分别增加了1.8、2.3和3.3 mL/kg/min。eGFR快速下降分别发生在117名(30%)、108名(28%)和92名(23%)参与者中。与对照组相比,中等强度组的相对危险度(RR)为0.93(0.75-1.16),高强度组的相对危险度(RR)为0.75 (95% CI 0.59-0.95),显示出显著的剂量-反应关系(P为趋势值0.02)。在观察性分析中,在调整基线年龄、性别、vo2峰值和eGFR后,中高强度运动(> +20分钟/周)减少的参与者与稳定运动(> +20分钟/周)相比,eGFR快速下降的RR为1.30 (95% CI 0.93-1.83),而运动增加的参与者(> +20分钟/周)的RR为0.73(0.53-0.99)。结论:高强度间歇训练可显著降低老年人eGFR快速下降的风险。
期刊介绍:
The Journal of the American Society of Nephrology (JASN) stands as the preeminent kidney journal globally, offering an exceptional synthesis of cutting-edge basic research, clinical epidemiology, meta-analysis, and relevant editorial content. Representing a comprehensive resource, JASN encompasses clinical research, editorials distilling key findings, perspectives, and timely reviews.
Editorials are skillfully crafted to elucidate the essential insights of the parent article, while JASN actively encourages the submission of Letters to the Editor discussing recently published articles. The reviews featured in JASN are consistently erudite and comprehensive, providing thorough coverage of respective fields. Since its inception in July 1990, JASN has been a monthly publication.
JASN publishes original research reports and editorial content across a spectrum of basic and clinical science relevant to the broad discipline of nephrology. Topics covered include renal cell biology, developmental biology of the kidney, genetics of kidney disease, cell and transport physiology, hemodynamics and vascular regulation, mechanisms of blood pressure regulation, renal immunology, kidney pathology, pathophysiology of kidney diseases, nephrolithiasis, clinical nephrology (including dialysis and transplantation), and hypertension. Furthermore, articles addressing healthcare policy and care delivery issues relevant to nephrology are warmly welcomed.
