摘　　要：[目的]研究绝经期女性日常饮食中摄入大豆异黄酮的量与尿液中钙、镁排泄量的相关关系.[方法]选择绝经期女性共162名(实验组为87名,对照组为75名),进行体格检查、骨密度测定、饮食摄入量调查及尿液中钙和镁排泄量测定.[结果]实验组和对照组在身高、体重、体重指数、闭经年龄和收缩压和舒张压等方面差异均无统计学意义(P>0.05).对照组豆类摄入量为50.70g,实验组为36.11g,相比较差异具有统计学意义(P<0.001);对照组异黄酮的摄入量为48.56mg,实验组为29.19mg(P<0.001),其中对照组和实验组4,7-二羟基异黄酮和染料木黄酮的摄入量分别为21.84mg和13.64mg,26.72mg和15.55mg,相比较差异具有统计学意义(P<0.001).对照组尿液中每日钙的排泄量为177.05mg,实验组为200.16mg,对照组每日镁的排泄量为133.58mg,实验组为147.97mg,实验组均明显高于对照组,差异具有统计学意义(P<0.05).[结论]绝经期女性日常饮食中异黄酮摄入量与尿液中的钙、镁的排泄量有相关性.OBJECTIVE To analysis the relationship between isoflavone intake and excretion of calcium and magnesium in postmenopausal women.METHODS 162 of postmenopausal women,including 87 cases in experimental group and 75 in control group,were selected,and body examination,bone density measurement,dietary intake investigation,and measurement of calcium,magnesium and deoxypyridinoline excretion were implemented.RESULTS There were no significant differences of the height,weight,BMI,amenorrhea age,DBP,and SBP between two groups（P0.05）.The intake of beans（50.70 g vs 36.11 g）,isoflavone（48.56 mg vs 29.19 mg）,4,7-dihydroxyisoflavone（21.84 mg vs 13.64 mg） and genistein（26.72 mg vs 15.55 mg） of the control group were all significantly higher than the experimental group（P0.001）.And the daily magnesium excretion（133.58 mg vs 147.97 mg） and calcium excretion（177.05 mg vs 200.16 mg）of the control group was lower in the experimental group（P0.05）.CONCLUSION The acceptable daily intake of isoflavone in the postmenopausal women is closely related to the excretion of calcium and magnesium from urine.
