Abstract

Objective

The impact of tea on bone health in postmenopausal women has generated conflicting opinions. The current study pooled previous research to evaluate the relationship between tea consumption and bone health in postmenopausal women.

Methods

Relevant papers published before October 2024 were included by conducting a comprehensive literature search in the Embase, PubMed, Scopus, and The Cochrane Library databases. Observational studies reporting the association between tea consumption and bone mineral density (BMD) or the risk of osteoporosis and fractures in women after menopause were deemed eligible. The weighted mean difference (WMD) for BMD and the pooled odds ratio (OR) for osteoporosis and fractures were calculated, together with their corresponding 95% confidence intervals (CIs).

Results

The meta-analysis examined 18 studies with a total of 48,615 individuals. The combined results indicated that postmenopausal women who consumed tea had higher BMD at several skeletal sites, including the lumbar spine (WMD, 0.02; 95% CI, 0.01–0.04; P < 0.001), greater trochanter (WMD, 0.02; 95% CI, 0.02–0.03; P < 0.001), femoral neck (WMD, 0.01; 95% CI, 0.00–0.02; P = 0.049), and ward’s triangle (WMD, 0.02; 95% CI, 0.01–0.03; P = 0.002). Additionally, these women had a lower risk of osteoporosis (OR, 0.41; 95% CI, 0.26–0.67; P < 0.001) and fracture (OR, 0.81; 95% CI, 0.67–0.98; P = 0.031).

Conclusions

The findings of this meta-analysis suggest that postmenopausal women who regularly consumed tea saw an increase in BMD and a decreased likelihood of developing osteoporosis and experiencing fractures. Future research should give priority to conducting prospective cohort studies with a more stringent methodology to verify the dose–response connection between tea consumption and the risk of osteoporosis or fracture in postmenopausal women.

绝经后妇女饮茶与骨骼健康：系统回顾和荟萃分析

目的茶对绝经后妇女骨骼健康的影响产生了相互矛盾的观点。目前的研究汇集了之前的研究，以评估绝经后妇女喝茶与骨骼健康之间的关系。方法综合检索Embase、PubMed、Scopus和Cochrane图书馆数据库，纳入2024年10月前发表的相关论文。报告饮茶与绝经后女性骨密度（BMD）或骨质疏松和骨折风险之间关系的观察性研究被认为是合格的。计算骨密度的加权平均差（WMD）和骨质疏松症和骨折的合并优势比（OR）及其相应的95%置信区间（ci）。结果荟萃分析检查了18项研究，共48,615人。综合结果表明，绝经后喝茶的妇女在几个骨骼部位的骨密度更高，包括腰椎(WMD, 0.02；95% ci, 0.01-0.04；P < 0.001)，大转子(WMD, 0.02；95% ci, 0.02-0.03；P < 0.001)，股骨颈(WMD, 0.01；95% ci, 0.00-0.02；P = 0.049)， ward三角形(WMD, 0.02；95% ci, 0.01-0.03；p = 0.002)。此外，这些女性患骨质疏松症的风险较低(OR, 0.41；95% ci, 0.26-0.67；P < 0.001)和骨折(OR, 0.81；95% ci, 0.67-0.98；p = 0.031)。这项荟萃分析的结果表明，经常喝茶的绝经后妇女的骨密度增加，患骨质疏松症和骨折的可能性降低。未来的研究应优先考虑采用更严格的方法进行前瞻性队列研究，以验证饮茶与绝经后妇女骨质疏松或骨折风险之间的剂量-反应关系。系统评审注册：PROSPERO注册号CRD42019112196。

期刊介绍： Archives of Osteoporosis is an international multidisciplinary journal which is a joint initiative of the International Osteoporosis Foundation and the National Osteoporosis Foundation of the USA. The journal will highlight the specificities of different regions around the world concerning epidemiology, reference values for bone density and bone metabolism, as well as clinical aspects of osteoporosis and other bone diseases.
