In order to study changes in the calcium depots of the body during pregnancy and lactation, bone mineral deteminations were performed on fourteen pregnant women and eighteen mothers post partum by X-ray spectrophotomeyry. Pregnant women exhibited a loss in trabecular bone but not in cortical bone when measured once during late first or early second trimester and again one week post partum. Lactating women who nursed less than three months lost mineral during the first three months and than regained it while those who nursed for longer than three months had no losses during six months of study.
为了研究妊娠和哺乳期身体钙库的变化，通过X射线分光光度法对14名孕妇和18名产后母亲进行了骨矿物质测定。在妊娠早期末或妊娠中期初测量一次，产后一周再测量一次，结果显示孕妇小梁骨有丢失，但皮质骨无丢失。哺乳少于三个月的哺乳期妇女在头三个月矿物质流失，之后恢复，而哺乳超过三个月的妇女在六个月的研究期间没有矿物质流失。
