| 目的 <\b>探讨饮茶与骨质疏松性髋骨骨折的关系.方法 <\b>采用1∶1配对病例对照方法,于2008年1月至2012年6月通过面对面访问,对广东省4家医院581例55～80岁中老年骨质疏松性髋骨骨折新发病例及性别、年龄(±3岁)配对的581名对照进行问卷调查.调查内容包括一般情况、详细的饮茶及其他饮食情况、健康相关行为和骨折家族史等.结果 <\b>单因素条件logistic分析显示,饮茶显著降低髋骨骨折风险.饮茶年限越长,每周饮茶次数越多,每年饮茶量越多,饮茶总量越多,或饮茶越浓,骨折发生的危险就越低(趋势检验P＜O.05).与不饮茶者相比,饮茶及不同时间、频率、剂量及不同茶叶类型者的OR值为0.54 ～ 0.74(P＜0.05).在校正年龄、能量、BMI、文化程度、父母骨折病史、“二手烟”暴露史、是否服用钙补充剂及体力活动能量消耗当量等因素后,上述关联仍具显著的线性趋势,但关联的强度略微降低.分层分析显示饮茶的效应仅在男性中有统计学意义,在不同文化程度人群亚组中的差异无统计学意义.结论 <\b>规律性饮茶可降低中老年男性骨质疏松性髋骨骨折的风险. |

| Objective <\b>To assess the impact of tea consumption on the risk of osteoporotic hip fractures.Methods <\b>Between January 2008 and June 2012,581 (148 males,433 females) incident cases of hip fractures were enrolled from four hospitals in Guangdong province,with 581 sex-and age-matched (± 3 years) controls from either hospitals or communities.Face-to-face interviews wer conducted to collect data pertaining to tea drinking and various covariates.Results <\b>Results <\b>from univariate conditional logistic analyses showed that an inverse association was observed in tea drinking and hip fracture risk.Longer time,greater frequency and dosage of tea consumption were dose-dependently associated with lower risk of hip fractures (P-trend ＜0.05).Compared to non drinkers,the odd ratios related to regular tea drinkers,subgroups with different length,frequency,dosage,type of tea consumption were ranged between 0.54 and 0.74 (all P＜0.05).After adjustment for factors as age,daily energy intake,BMI,education levels,passive smoking,calcium supplement and physical activity,the dose-dependent associations among above said factors still remained significant.However,the strength of the association lowered slightly.The beneficial effect of tea was significant only in men but not in women.Similar effects were found in subjects with different education levels.Conclusion <\b>Regular tea drinking habit might decrease the risk of osteoporotic hip fractures in the elderly males. |
