目的 探讨大学生的尿钠、钾、钙与骨密度及骨矿物含量的关系。方法 随机抽样调查１０５ 名大学生，用骨密度仪测定左前臂骨密度和骨矿物含量，同时收集４ 小时尿液，测定尿 Ｎａ、 Ｋ、 Ｃａ 含量。结果 尿钙与尿钠为显著性正相关（ Ｐ＜ ０．０１），而尿钙与尿钾为负相关，但未出现显著性（ Ｐ＞ ０．０５），说明尿钙排出可能与膳食中的食盐消耗有关系。尿钙与骨密度及骨矿物含量为负相关（ Ｐ＜ ０．０１），但尿钠、尿钾与骨密度未呈现显著性的负相关，可能与本人群膳食差异较小有关。结论 膳食的钠可能影响钙代谢，从而可能影响骨骼的矿物含量。
Objective To investigate the relationship between urinary sodium, potassium, calcium and bone mineral density in college students. Methods A total of 105 college students were randomly sampled. BMD and bone mineral content of the left forearm were measured by bone densitometry. Urinary Na, K and Ca contents were measured after urine collected for 4 hours. Results Urinary calcium was positively correlated with urinary sodium (P <0.01), while urinary calcium was negatively correlated with urinary potassium, but no significant difference was found (P> 0.05), indicating that urinary calcium excretion may be correlated with dietary The consumption of salt is related. There was a negative correlation between urinary calcium and bone mineral density and bone mineral content (P <0.01). However, there was no significant negative correlation between urinary calcium, urinary potassium and bone mineral density. Conclusion Dietary sodium may affect calcium metabolism, which may affect bone mineral content.
