为了解青州市儿童的尿钙含量,以掌握儿童的缺钙情况,制订相应的补钙措施,我们于1997年8～11月对市内5所幼儿园、两所小学的儿童进行了尿钙测定.1 对象与方法1.1 对象 选取青州市5所幼儿园的学龄前儿童及两所小学的学生为调查对象,分学龄前组、小学生组,总计1778名.其中,男938名,女840名.1.2 方法 采用南京康得医药生物保健公司生产的尿钙/乳钙试剂盒,按说明用EDTA化学滴定法.取当天晨尿或者禁水1h之后的尿液送检.尿钙含量≥160mg/L判定为正常.2 结果2.1 在调查的1778名儿童中,缺钙710人,平均缺钙率39.93%,学龄前儿童缺钙率49.48%,小学生缺钙率35.31%,两者差异有非常显著性(X~2=43.75,P<0.005).见表1.学前组中,各幼儿园之间儿童缺钙率差异有非常显著性(X~2=55.18,P<0.005).见表2.小学生组中,各年级之间儿童缺钙率差异无显著性(X~2=3.69,P>0.05).见表3.
In order to understand the urinary calcium content of children in Qingzhou, calcium deficiency in children to grasp the situation, to formulate the corresponding calcium measures, we in August to November 1997 in the city five kindergartens, two primary school children were measured urinary calcium .1 Subjects and Methods 1.1 Subjects Preschool children and two primary school students from five kindergartens in Qingzhou City were selected as survey subjects, divided into preschool group and primary school pupils group, totaling 1778. Among them, 938 were male and 840 were female.1.2 Methods The calcium-calcium / lactate calcium kit produced by Nanjing Kangde Biomedical Health Care Company was used according to the instructions of EDTA chemical titration method, urine samples were taken after morning urine or water for 1h, urinary calcium content ≥ 160mg / L Normal.2 Results 2.1 Of the 1778 children surveyed, calcium deficiency was 710, the average calcium deficiency rate was 39.93%, preschool children calcium deficiency rate was 49.48%, primary calcium deficiency rate was 35.31%, the difference was significant X ~ 2 = 43.75, P <0.005) .Table 1. Pre-school group, the kindergarten children between the calcium deficiency rate differences were significant (X ~ 2 = 55.18, P <0.005) In children, there was no significant difference in calcium deficiency rate among all grades (X ~ 2 = 3.69, P> 0.05).
