对于无并发症妊娠和分娩的母亲所生的成熟婴儿，出生第一天低钙血症的发生率为 1.2%。
在我们对在怀孕和/或分娩期间出现并发症的母亲所生的一系列婴儿中，每个婴儿在出生第一天都出现低钙血症。
因头盆不称或“重复”剖腹产的婴儿低钙血症发生率为13.7%，而因母亲孕期出现病理状态剖宫产的婴儿低钙血症发生率为36.8%。
当我们研究早产儿出生第一天低钙血症的发生率时，妊娠和/或分娩期间并发症的影响并不明显。我们注意到，出生途径或怀孕和/或分娩期间是否存在并发症并不会显着影响出生第一天低钙血症的发生率。
早产儿体重与血浆钙总浓度呈显着正相关。
所研究的早产儿血清中蛋白质和钙的平均浓度之间不存在显着的统计相关性。
我们推测，由于早产发生在妊娠晚期，肾上腺皮质类固醇在此期间在母体血清中达到最高浓度，可能会对婴儿血浆中钙的浓度产生抑制作用。
The incidence of hypocalcemia on the first day of life in mature infants born to mothers per vias naturales who had uncomplicated pregnancies and labors is 1.2%.
In our series of infants born to mothers who had complications during pregnancies and/or labors, every one had hypocalcemia on the first day of life.
Infants delivered by cesarean section because of cephalopelvic disproportion or because of "repeat" section had an incidence of hypocalcemia of 13.7% while those infants delivered by section because their mothers had pathologic states during pregnancy had an incidence of 36.8%.
The effect of complications during pregnancy and/or labor was not apparent when we studied the incidence of hypocalcemia in premature infants on the first day of life. We noted that the avenue of birth or the presence or absence of complications during pregnancy and/or labor did not affect significantly the incidence of hypocalcemia on the first day of life.
There is a significant positive correlation between weight of the premature infant and the total concentration of calcium in the plasma.
There was no significant statistical correlation between the mean concentrations of protein and of calcium in the serums of the premature infants studied.
We have speculated that, because premature births occur during the third trimester of pregnancy, the adrenocorticosteroids, which attain their highest concentration in the maternal serum during this period, may exercise a depressing effect on the concentrations of calcium in plasma of infants.
