目的 调查老年人服用维生素D和碳酸钙复方制剂(以下简称钙剂)与肾结石发病率的关系.方法 对556例经B超检查排除有肾结石的老年人进行长期随访,然后分析服用钙剂与肾结石发病率的关系.结果 平均随访3.8年后,老年人肾结石发病率为5.58%,其中男性(5.68%)与女性(5.38%)肾结石发病率无明显差异(P>0.05).老年人服用钙剂与肾结石的发病率无关(P>0.05).结论 老年人服用钙剂不会增加肾结石的发病率.

Objective To explore the relationship between supplement of calcium carbonate and vitamin D compound(calcium compound) and prevalence rate of kidney stone in persons aged 60 and over. Methods A cross-sectional survey was conducted in a cohort comprising 556 persons aged 60 and over. All participants underwent questionnaire survey on supplement of calcium compound. Ultrasound examination of double kidneys was conducted,and the relationship between supplement of calcium compound and prevalence rate of kidney stone were analyzed. Results Kidney stone was found in 5.58% persons aged 60 and over. The prevalence rate of kidney stone in men was not significantly higher than that in women(5.68% vs 5.38%,P>0.05),there was no significant relationship between supplying calcium compound and prevalence rate for kidney stone(P>0.05). Conclusion Calcium intake does not increase the incidence of kidney stones in the elderly.
