摘要
对447份不同泌乳期的乳汁进行了钙含量测定,并对其中35例乳母同时进行了血钙、碱性磷酸酶及尿钙的测定,发现初乳(7.37mmol/L)、过渡乳(7.60mmol/L)钙含量显著低于35～60天的成熟乳(8.34mmol/L)(P<0.05).冬季母乳钙含量显著低于春夏秋三季(P值均<0.05);依据单侧95%的参考范围,推荐以7.0mmol/L作为母乳钙含量的低限,并发现71.4%的乳母低于此值,有缺钙.提示母乳钙定量测定,既可推算出婴儿对钙的摄入量,又可了解乳母的钙营养状况,是对母婴补钙的科学依据.
The calcium contents of breast milk (BM) in 447 mothers during their various lactation periods were measured. Meanwhile, in 35 of them the serum calcium, alkaline phosphokinase and uric calcium were also measured. The result revealed that the calcium contents of colostrum (7. 37 mmol/L) and transition BK (7. 60 mmol/L) were significantly lower than that of mature BK (8. 34 mmol/L) 36-60 days postnataly (P<0. 05) , and in winter the calcium content of BK was also obviously lower than that in spring、 summer and autumn (P<0. 05). According to the reference values of one-sided test 95% ,we recommened 7. 0 mmol/L as the low limit of calcium content of BK. We found that the mothers whose calcium content of BK were lower than the limit were short of calcium. Our study suggested that with the measurement of calcium content of BK we can evaluate the calcium amount intaked by infant, and find out the mother's nutritional status of calcium. Therefore the means will be used as the scientific basis for calcium supplement of the mother and baby.
