The hair and serum levels of calcium, iron, copper, and zinc levels were measured in a group of 70 healthy pregnant women and in 66 age-matched healthy controls living in the Tianjin city of the People's Republic of China. The study subjects were classified into three subgroups according to gestational age. The hair concentrations were measured by X-ray fluorescence spectrometry, whereas those in sera were established by atomic absorption spectrometry. The hair concentrations of Ca, Fe, Cu, and Zn in the three groups of gravida were lower or significantly lower than those in controls. In sera, the differences did not show statistical significance in most cases. A deficiency of calcium was observed in subjects in the last trimester of gestation. This reinforces the importance of supplementation with calcium during pregnancy.
对居住在中华人民共和国天津市的70名健康孕妇和66名年龄匹配的健康对照者进行了头发和血清中钙、铁、铜和锌水平的测量。研究对象根据孕周分为三个亚组。头发浓度通过X射线荧光光谱法测量，而血清中的浓度通过原子吸收光谱法测定。三组孕妇头发中钙、铁、铜和锌的浓度低于或显著低于对照组。在血清中，大多数情况下差异无统计学意义。在妊娠晚期的受试者中观察到钙缺乏。这强化了孕期补钙的重要性。
