本研究用全钙摄入和不同水平的钙摄入比较了老年男性和女性尿钠与钙之间的关系，并检测了同一人群尿钠排泄与骨矿物质密度之间的关系。结论是，健康的老年男性和女性于中等和高钙摄入时，尿钠和钙排泄是有关联的，而于低钙摄入时则无关联。对于一个给定的钠排泄而言，老年男性的排钙量高于女性。 In this study, the relationship between urinary sodium and calcium in elderly men and women was compared with total calcium intake and different levels of calcium intake, and the relationship between urinary sodium excretion and bone mineral density was examined in the same population. In conclusion, urinary sodium and calcium excretion were associated with moderate and high calcium intake in healthy elderly men and women, but not in low calcium intake. For a given sodium excretion, elderly men have higher levels of calcium than women.
