目的:通过网状Meta分析比较有氧运动、抗阻运动、多元运动和身心运动(MBE)对主观记忆抱怨(SMCs)老年人认知功能的干预效果.方法:计算机检索Scopus、PubMed、Web of Science、Embase、The Cochrane Library、CNKI、VIP、CBM、Wanfang数据库,搜集探究运动干预对SMCs老年人影响的随机对照试验(RCT),检索时限从建库至2022年6月.结果:共纳入7项RCT,917例患者.网状Meta分析结果显示:4种运动方式对整体认知功能的影响差异均无统计学意义(P>0.05);MBE对记忆功能的效果优于其他组(P<0.05),且4种运动类型均优于对照组(P<0.05);MBE改善执行功能效果优于对照组(P<0.05).SUCRA概率排序结果显示:MBE增强SMCs老年人的整体认知功能、记忆功能、执行功能的效果最好.结论:MBE可能是改善SMCs老年人认知功能的最佳运动方式.受纳入研究数量和质量的限制,上述结论尚需更多高质量研究予以验证.
Effects of various exercise interventions on cognitive function in older adults with subjective memory complaints:A network meta-analysis
Objective:To compare the effects of aerobic exercise,resistance exercise,multi-component ex-ercise,and mind-body exercise(MBE)on cognitive function in older adults with subjective memory complaints(SMCs)using network meta-analysis.Methods:We searched the Scopus,PubMed,Web of Science,Embase,Cochrane Library,CNKI,VIP,CBM,and Wanfang databases to collect ran-domized controlled trials(RCTs)about the effects of exercise interventions on elderly with SMCs from inception to June 2022.Results:A total of 7 RCTs with 917 patients were included.Network meta-analysis results showed no significant difference in global cognitive function effects among four exercise types(P>0.05).MBE improved memory function better than other groups(P<0.05),and all four types of exercise were better than control group(P<0.05).MBE improved executive function better than the control group(P<0.05).The SUCRA probability sorting results showed that MBE had the most significant effect on cognitive function improvement among the elderly with SMCs.Conclusion:MBE may be the most effective exercise method to improve cognitive function for the el-derly with SMCs.Due to the limited quantity and quality of the included studies,the above conclu-sions need to be verified by more high-quality studies.
