为了解妇女乳钙、尿钙和儿童尿钙水平，找出低钙的原因和防治因缺钙引起的一系列疾病，用EDTA滴定法对375名妇女和1169名3～6岁儿童尿钙进行检测，对66名产妇初乳钙及其所生新儿尿钙进行检测，对50名低钙儿童补钙后的尿钙进行复测。结果表明，孕妇（包括正常与非正常孕妇）尿钙低钙率74．8％，其中正常孕妇尿钙低钙率71．2％，妊高征妇女尿钙低钙率92．9％，非孕妇尿钙低钙率64．5％，产妇初乳钙低钙率68．2％．相应新生儿尿钙低钙率54．6％，散居和集体儿童尿钙低钙率分别为73．1％和69．3％，低钙儿童经补钙后尿钙明显升高，有88％达到正常水平。提示妇女、儿童普遍低钙，尤其孕妇缺钙严重；母乳钙含量的变化直接影响新生儿尿钙含量的变化，并呈正相关关系；合理饮食或药物补钙可以纠正低钙，正确补充钙营养对防治缺钙引起的一系列疾病有重要作用。
In order to understand women’s milk calcium, urinary calcium and urinary calcium levels in children, to find out the causes of low calcium and prevention and treatment of calcium deficiency caused by a series of diseases, EDTA titration of 375 women and 1169 children aged 3-6 urinary calcium Detection, 66 maternal colostrum calcium and urine of newborn urine tests were carried out on 50 low calcium children calcium calcium after retest. The results showed that pregnant women (including normal and abnormal pregnant women) 74.8% of urinary calcium low calcium, including normal pregnant women urinary calcium low calcium rate 71.2%, PIH women urinary calcium low calcium rate 92.9% Pregnant women urinary calcium low calcium rate 64.5%, maternal colostrum calcium low calcium rate 68.2%. Correspondingly, the rate of urinary calcium and calcium in newborns was 54.6%, urinary calcium and calcium in diaspora and collective children were 73.1% and 69.3%, urinary calcium in low calcium children was obviously increased after calcium supplement, 88% Reach normal level Prompted that women, children generally low calcium, especially pregnant women, calcium deficiency; changes in breast milk calcium directly affect the changes in urinary calcium, and a positive correlation; reasonable diet or drug calcium can correct low calcium, correct calcium nutrition Prevention of calcium deficiency caused by a series of diseases have an important role.
