Mixed results have been reported regarding whether habitual tea intake affects bone health. This study investigated the relationship between green tea intake and bone mineral density (BMD) in postmenopausal Korean women. We used data from the Korean National Health and Nutrition Examination Surveys from 2008 to 2011 and divided the participants into three groups according to their frequency of green tea intake over the past 12 months. BMD of the lumbar spine, total femur, and femur neck was measured using dual-energy X-ray absorptiometry. The odds ratios (ORs) and 95% confidence intervals (CIs) of osteoporosis and osteopenia according to green tea consumption were analyzed. Participants who did not consume green tea or consumed less than one cup per day were more likely to have osteopenia of the lumbar spine or femur than those who consumed it once to three times a day (OR 1.81 and 1.85, 95% CI, 1.20-2.71; and 1.23-2.77). Moreover, ORs for osteoporosis were 1.91 (95% CI 1.13-3.23) and 1.82 (95% CI 1.09-3.05) in non-consumers and consumers who drank less than one cup per day, respectively, compared with the reference group. These results support that green tea consumption may have benefits on bone health.
关于习惯性饮茶是否影响骨骼健康，研究结果喜忧参半。本研究调查了绿茶摄入量与绝经后韩国女性骨密度（BMD）之间的关系。我们使用了 2008 年至 2011 年韩国国家健康和营养检查调查的数据，并根据过去 12 个月内绿茶的摄入频率将参与者分为三组。使用双能 X 射线吸收法测量腰椎、全股骨和股骨颈的 BMD。分析了根据绿茶消费情况骨质疏松症和骨量减少的比值比（OR）和 95%置信区间（CI）。与每天饮用 1 次至 3 次绿茶的人相比，不饮用或每天饮用少于 1 杯绿茶的人更有可能出现腰椎或股骨骨量减少（OR 1.81 和 1.85，95%CI，1.20-2.71；1.23-2.77）。此外，与对照组相比，不饮用绿茶和每天饮用少于 1 杯绿茶的人的骨质疏松症的 OR 分别为 1.91（95%CI 1.13-3.23）和 1.82（95%CI 1.09-3.05）。这些结果支持绿茶摄入可能对骨骼健康有益。
