This study was conducted to determine 1) the incidence of diastasis recti abdominis among women during the childbearing year and 2) the location of the condition along the linea alba. Clinicians have long noted its presence, prenatally and postnatally, but the magnitude of the problem is currently unknown. A cross-sectional design was used to test 71 primiparous women placed in one of five groups, based on placement within the childbearing year. A commonly accepted test for diastasis recti abdominis was performed. Palpation for diastasis recti abdominis at the linea alba was performed 4.5 cm above, 4.5 cm below, and at the umbilicus. Diastases were observed at all three places, but most often at the umbilicus. A significant relationship (p less than .05) was found between a woman's placement in her childbearing year and the presence or absence of the condition. Diastasis recti abdominis was observed initially in the women in the second trimester group. Its incidence peaked in the third trimester group; remained high in the women in the immediate postpartum group; and declined, but did not disappear, in the later postpartum group. These findings demonstrate the importance of testing for diastasis recti abdominis above, below, and at the umbilicus throughout and after the childbearing year.
1）育龄期女性腹直肌分离的发生率；2）腹直肌分离沿白线的位置。临床医生长期以来一直注意到其在产前和产后的存在，但目前尚不清楚该问题的严重程度。采用横断面设计，根据在育龄期内的所处阶段，对71名初产妇进行分组测试，分为五组。采用一种普遍认可的腹直肌分离测试方法。在白线处分别于脐上4.5厘米、脐下4.5厘米及脐部进行腹直肌分离触诊。在所有三个部位均观察到了腹直肌分离，但最常出现在脐部。发现女性在其育龄期内的所处阶段与腹直肌分离情况的有无之间存在显著关系（p小于0.05）。腹直肌分离最初在孕中期组的女性中被观察到。其发生率在孕晚期组达到峰值；在产后即刻组的女性中仍保持较高水平；在产后后期组有所下降，但并未消失。这些发现表明，在整个育龄期及产后，对脐上、脐下及脐部进行腹直肌分离测试具有重要意义。
