太极拳对中老年人群血脂水平影响的Meta分析

Meta-Analysis of the Effect of Tai Chi on Blood Lipid Levels in Middle-Aged and Elderly Groups

目的:系统评价太极拳对中老年人群血脂水平的影响。方法:检索中国知网CNKI数据库、万方数据知识服务平台、维普中文期刊服务平台、PubMed、SCI-科学引文索引网络版、RSC电子期刊数据库,检索年限为2011年1月至2021年5月,收集太极拳对中老年人群血脂水平影响的随机对照实验,采用Revman5.3进行统计学分析。结果:本次实验共纳入了8项研究,分别针对总胆固醇(TC)、血浆甘油三酯(TG)、低密度脂胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C) 4项指标进行分析。根据Meta分析结果显示:总胆固醇(TC):[SMD = −0.23, 95%CI (−0.43,−0.03), P = 0.02];血浆甘油三酯(TG):[SMD = −0.33, 95%CI (−0.53, −0.13), P = 0.0010];低密度脂胆固醇(LDL-C):[SMD = −0.60, 95%CI (−0.99, −0.20);P = 0.003];高密度脂蛋白胆固醇(HDL-C):[SMD = 0.83, 95%CI (0.36, 1.30), P = 0.0006],其中以高密度脂蛋白胆固醇(HDL-C)为结局指标的研究对象均为中老年女性,表现为总胆固醇(TC)、血浆甘油三酯(TG)、低密度脂胆固醇(LDL-C)水平降低,高密度脂蛋白胆固醇(HDL-C)水平升高。干预组的4项结局指标结果均优于对照组,且其差异存在统计学意义。对纳入研究进行亚组分析发现:与中老年人群组相比太极拳对中老年女性总胆固醇(TC)、血浆甘油三酯(TG)、低密度脂胆固醇(LDL-C)水平的降低效果更为显著。结论:太极拳有助于降低中老年人群的血脂水平,且更有利于降低中老年女性的血脂水平,能够改善当前我国中老年人群健康状况。

Objective: To systematically evaluatethe effects of Taijiquan on blood lipid levels in middle-aged and elderly people. Methods: The CNKI database, WanfangData Knowledge Service Platform, Weipu Chinese Journal Service Platform,PubMed, SCI-Science Citation Index online version, and RSC electronic journal databasewere searched from January 2011 to May 2021. The randomized controlled trials onthe effects of Tai Chi on blood lipid levels in middle-aged and elderly people werecollected. Revman5.3 was used for statistical analysis. Results: A total of 8 studieswere included in this experiment, and four indexes of total cholesterol (TC), plasmatriglyceride (TG), low density fat cholesterol (LDL-C) and high density lipoproteincholesterol (HDL-C) were analyzed. According tothe Meta analysis results showed that total cholesterol (TC): [SMD = −0.23, 95%CI(−0.43, −0.03), P = 0.02);Plasma triglycerides (TG): [SMD = −0.33, 95%CI(−0.53, −0.13), P = 0.0010). Low density fat cholesterol (LDL-C): [SMD = −0.60,95%CI (−0.99, −0.20), P = 0.003);High-density lipoprotein cholesterol (HDL-C):[SMD = 0.83, 95%CI (0.36, 1.30), P = 0.0006]. Subjects with high density lipoproteincholesterol (HDL-C) as outcome index were all middle-aged and elderly women, withdecreased levels of total cholesterol (TC), plasma triglyceride (TG) and low densityfat cholesterol (LDL-C). Levels of high-density lipoprotein cholesterol (HDL-C)are elevated. The results of 4 outcome indicators in the intervention group werebetter than those in the control group, and the differences were statistically significant.Subgroup analysis of the included studies found that Tai Chi had a more significant effect on the reductionof total cholesterol (TC), plasma triglyceride (TG) and low density fat cholesterol(LDL-C) levels in middle-aged and elderly women compared with the middle-aged andelderly group. Conclusion: Tai Chi is helpful to reduce the blood lipid level ofmiddle-aged and elderly people, and more conducive to reduce the blood lipid levelof middle-aged and elderly women, and can improve the current health status of middle-agedand elderly people in China.
