微量营养素补充剂在降低老年人的死亡率或改善老年人的脆弱性方面没有明显的好处. 需要更多的研究来确定维生素和矿物质是否可以有效地对抗虚弱.
科学领域:
- 老年学是一门学科.
- 营养科学 营养科学
- 临床试验 临床试验
背景情况:
- 维生素和矿物质水平较低与脆弱性增加有关.
- 微量营养素补充剂对脆弱个体的有效性尚未得到充分证实.
研究的目的:
- 系统地审查对脆弱个体的微量营养素补充的随机对照试验.
- 评估补充剂对所有原因死亡率和脆弱性水平的影响.
主要方法:
- 在PubMed和Embase的系统文献搜索,截至2025年6月10日.
- 包括21个随机对照试验,涉及脆弱人群的补充剂.
- 对结果的元分析,包括全因死亡率和脆弱性的变化.
主要成果:
- 维生素D补充剂没有显著影响所有原因的死亡率 (合并RR:1.04,95%CI:0.83至1.31) 具有中等的确定性.
- 多组分补充剂对脆弱水平没有显著影响 (汇总的MD = -0.28,95%CI: -0.71至0.16),确定性非常低.
- 对于其他微量营养素,如尼古丁胺胺,数据有限.
结论:
- 目前的证据不支持对脆弱个体进行微量营养素补充的常规处方.
- 未来的研究应该优先考虑对脆弱性,认知功能和功能性措施的纵向评估.
