Abstract
This meta-analysis included 16 studies, involving seven cohort studies and nine case-control studies, and the results indicated that tea consumption may be associated with a reduced the risk of fractures. INTRODUCTION: Regarding relationship of tea consumption with the risk of fractures remains controversial. We performed a meta-analysis to elucidate the association between tea consumption and the risk of fractures. METHODS: Relevant articles were identified up to March 2019 by searching PubMed, Web of Science, and Embase databases. The pooled relative risks (RRs) with 95% confidence intervals (CIs) were computed utilizing fixed or random effects model based on heterogeneity. RESULTS: Altogether 16 studies (seven cohort and nine case-control studies) were included in this meta-analysis, involving 772,707 participants with 37,166 fracture cases. The RRs (95% CIs) of fracture for the highest versus lowest category of tea consumption were 0.86 (0.78-0.94). Subgroup analysis indicated significant associations in cohort studies (0.90 (0.86-0.94)) and case-control studies (0.77 (0.69-0.85)). CONCLUSIONS: The current meta-analysis indicates that tea consumption may be associated with a reduced the risk of fractures.
