Serum calcium, phosphate and alkaline phosphatase, and urinary calcium excretion were examined during the second trimester of uncomplicated normal pregnancy in Asian immigrants to Britain and in local Caucasians. The mean serum calcium was significantly lower in Asians than in Caucasians, and the mean serum alkaline phosphatase was significantly higher in Asians. The geometric mean of the urinary calcium excretion was highly significantly lower in Asians than in Caucasians. The variances of the serum calcium, serum alkaline phosphatase, and urine calcium excretion did not differ significantly in the two populations. This indicates that there is a shift in values of immigrant Asians as a group compared with Caucasians. A comparison with figures obtained on normal nonpregnant persons of both suggests that the shift is not an inherent feature of the Asian population.
对移居英国的亚洲移民和当地白种人的正常非复杂妊娠中期孕妇进行了血清钙、磷、碱性磷酸酶以及尿钙排泄检测。亚洲人的血清钙均值显著低于白种人,而血清碱性磷酸酶均值显著高于白种人。亚洲人的尿钙排泄几何均值显著低于白种人。血清钙、血清碱性磷酸酶和尿钙排泄的方差在两组人群中无显著差异。这表明与白种人相比,亚洲移民群体的各项数值发生了偏移。与正常非妊娠人群的数值比较表明,这种偏移并非亚洲人群的固有特征。
