The overall aim of this study is to determine if the calcium intake recommended during pregnancy is sufficient to provide for the high calcium requirements of two groups of high-risk pregnancies, adolescent singleton gestation and adult multiple gestations. The study will determine whether specific abnormalities of calcium and of the calcium regulating hormone, parathyroid hormone (PTH) and 1,25 (OH)2 Vitamin D, the active metabolite of vitamin D (calcitriol), are related to calcium intake in adolescent pregnancies and adult multiple gestation. This study may provide important information that could lead to the understanding of the possible increased calcium needs of these two highly important groups of pregnancies, and provide important information that could lead to the reduction of high blood pressure during pregnancy. This project utilizes the resources of the CRC Core Laboratory only for the above-mentioned determinations. There are no inpatient or outpatient visits.

本研究的总体目的是确定怀孕期间建议的钙摄入量是否足以满足两组高风险妊娠（青少年单胎妊娠和成人多胎妊娠）的高钙需求。 该研究将确定钙和钙调节激素、甲状旁腺激素 (PTH) 和 1,25 (OH)2 维生素 D（维生素 D（骨化三醇）的活性代谢物）的特定异常是否与青少年妊娠和成人多胎妊娠中的钙摄入量有关。 这项研究可能提供重要信息，帮助人们了解这两个非常重要的妊娠群体可能增加的钙需求，并提供有助于降低妊娠期间高血压的重要信息。 本项目仅利用CRC核心实验室的资源进行上述测定。 没有住院或门诊就诊。
