Exploring maternal hydration status for safe and healthy pregnancy outcomes

这项前瞻性队列研究探讨了评价母体水合状态的指标。这些指标包括使用多频生物电阻抗分析仪评估的生物阻抗值。对332名健康单胎孕妇的资料进行分析，发现在“疑似早产”和“低出生体重”组中，存在较高的抵抗力（R）值或较高的血红蛋白（Hb）值，表明较低的水合状态和较低的血浆容量。较低的R值和较高的Hb值，表明较高的水合状态和较低的血浆容量，被发现在“血压升高后，34-36周的妊娠通过交付（EBP）”组。在这项研究中发现，可能的相关性的指标，有关产妇的水合状态，与负面的妊娠结局。未来的研究需要探索评价产妇水化状态和指示健康妊娠结局的指标。

This prospective cohort study explored indices for evaluating maternal hydration status. The indices included bioimpedance values that were evaluated using a multifrequency bioelectrical impedance analyzer. Data from 332 participants, who were healthy singleton pregnant women, were analyzed.Higher resistance (R) values or higher hemoglobin (Hb) values, suggesting lower hydration status and lower plasma volumes, were found in a "suspected preterm labor (SPTL)" and a "low birth weight (LBW)" groups. Lower R values and higher Hb values, suggesting higher hydration status and lower plasma volumes, were found in a "elevated blood pressure after 34-36 weeks of gestation through to delivery (EBP)" group. Possible correlations of indices, related to maternal hydration status, with negative pregnancy outcomes were found in this study. Future studies are needed to explore the indices for evaluating maternal hydration status and for indicating healthy pregnancy outcomes.
