BACKGROUND/AIM: This study explored the correlation between maternal muscle mass and strength and the mode of delivery in childbirth. Specifically, it focused on full-term nulliparous pregnant women, analyzing ultrasonographic measurements of the quadriceps femoris muscle together with serum myostatin levels and muscle strength as determined by a handgrip test. The aim was to discern whether these factors could influence the likelihood of delivering vaginally or via cesarean section.
This study included 86 healthy nulliparous women at term, categorizing them into two groups based on their mode of delivery: vaginal delivery (58 women, Group 1) and cesarean section (28 women, Group 2). Comparative analyses of demographic information, delivery characteristics, ultrasonographic measurements of the quadriceps femoris, limb circumferences, handgrip strength, and serum myostatin concentrations were conducted.
The findings revealed that women in Group 1 had less gestational weight gain but greater handgrip strength compared to Group 2. Additionally, women who underwent cesarean section due to nonprogressive labor had greater arm and calf circumferences relative to those who had vaginal deliveries.
The data of this study suggest a trend whereby lower maternal muscle strength and mass are associated with a decreased likelihood of vaginal delivery in pregnant women.
背景/目的：本研究旨在探讨产妇肌肉质量和力量与分娩方式之间的相关性。具体而言，本研究聚焦于足月初产妇，通过超声测量股四头肌，并结合血清肌肉生长抑制素水平和握力测试评估肌肉力量，旨在探讨这些因素是否会影响阴道分娩或剖宫产的可能性。
本研究纳入了 86 名健康的足月初产妇，根据分娩方式将其分为两组：阴道分娩组（58 名妇女，第 1 组）和剖宫产组（28 名妇女，第 2 组）。对比分析两组的人口统计学资料、分娩特征、股四头肌超声测量值、四肢周径、握力和血清肌肉生长抑制素浓度。
研究结果显示，第 1 组孕妇的体重增加量较少，但握力较大。此外，因产程无进展而进行剖宫产的产妇的手臂和小腿周径大于阴道分娩的产妇。
本研究数据表明，产妇肌肉力量和质量较低与阴道分娩可能性降低相关。
