背景:绝经后妇女的骨骼状况正在恶化。事实上,绝经后是骨质疏松和跌倒的高发阶段。值得注意的是,最近的一项研究指出,运动可以改善绝经后妇女的骨骼健康。然而,太极拳运动对绝经后妇女的影响存在争议。因此,一项荟萃分析旨在分析太极拳运动对绝经后女性骨骼健康和预防跌倒的影响.
方法:2023年8月31日前太极拳改善绝经后妇女骨骼健康的研究从中英文数据库收集,比如PubMed,Embase,和WebofScience,等。使用Cochrane偏倚风险工具对纳入研究的偏倚风险进行随机试验评估。此外,采用R软件4.3.1对meta分析中的效应大小进行分析,总结太极拳对椎体骨密度的影响,血清钙,临床平衡评分,跌倒的次数,总跌幅,绝经后妇女的健康状况评分。
结果:本荟萃分析最终纳入了12项研究。共有1272名绝经后妇女参与,其中实验组628例(采用太极拳运动干预),对照组644例(不采用任何干预)。简而言之,绝经后妇女练习太极拳表现出椎体骨密度的显着增加[标准化平均差(SMD)=0.37,95%置信区间(CI)(0.04-0.71),P=0.03]和健康状况评分[SMD=0.25,95%CI(0.01-0.49),P=0.04]。相比之下,两组绝经后妇女在血清钙方面没有显着差异[SMD=-0.01,95%CI(-0.39,0.36),P=0.77],临床平衡[SMD=0.17,95%CI(-0.01,0.46),P=0.23],跌倒次数[SMD=-0.61,95%CI(-1.24,0.02),P=0.06]和总跌倒[赔率=0.35,95%CI(0.11-1.12),P=0.07]。
结论:太极拳锻炼能提高绝经后妇女的骨密度,从而保持骨骼健康。因此,太极拳运动是预防骨质疏松症的必要条件。
BACKGROUND: The bone status of postmenopausal women is worsening. In fact, postmenopausal period is the high incidence stage of osteoporosis and falls. Notably, a recent study has pointed out that exercise can improve bone health in postmenopausal women. However, the effect of Tai Chi exercise on postmenopausal women is controversial. Therefore, a meta-analysis was designed to analyze the effect of Tai Chi exercise on bone health and fall prevention in postmenopausal women.
METHODS: The researches on Tai Chi improving the bone health of postmenopausal women before August 31, 2023 were collected from Chinese and English databases, such as PubMed, Embase, and Web of Science, etc. The risk of bias of the included studies was assessed using the Cochrane risk-of-bias tool for randomized trials. Besides, R software 4.3.1 was employed to analyze the effect sizes in the meta-analysis to summarize the impact of Tai Chi on vertebral bone mineral density, serum calcium, clinical balance scores, the number of falls, total falls, and health status scores in postmenopausal women.
RESULTS: There were 12 studies eventually included in this meta-analysis. A total of 1,272 postmenopausal women were involved, including 628 in the experimental group (intervention with Tai Chi exercise) and 644 in the control group (without any intervention). Briefly, postmenopausal women practicing Tai Chi presented a significant increase in vertebral bone density [standardized mean difference (SMD) = 0.37, 95% confidence interval (CI) (0.04-0.71), P = 0.03] and health status score [SMD = 0.25, 95% CI (0.01-0.49), P = 0.04]. In contrast, there were no significant differences for postmenopausal women between the two groups in terms of serum calcium [SMD = -0.01, 95% CI (-0.39, 0.36), P = 0.77], clinical balance [SMD = 0.17, 95% CI (-0.01, 0.46), P = 0.23], number of falls [SMD = -0.61, 95% CI (-1.24, 0.02), P = 0.06] and total falls [odds ratio = 0.35, 95% CI (0.11-1.12), P = 0.07].
CONCLUSIONS: Tai Chi exercise can improve the bone mineral density of postmenopausal women, thereby maintaining bone health. Hence, Tai Chi exercise is necessary to prevent osteoporosis.
