Weakness of the pelvic floor is quite common among women, and may occur following childbirth. The aim of this study was to compare pelvic floor muscle strength in women of reproductive age who were nulliparous or who had a cesarean section or normal vaginal delivery.
In this cross-sectional study, 341 women including 96 nulliparous women, 73 women with a history of normal vaginal delivery with and without episiotomy, and 172 women with a history of elective or emergency cesarean section were recruited randomly from public health centers in Ahvaz, Iran. Data were collected using a sociodemographic questionnaire and a checklist was used to record weight, height, body mass index, and pelvic floor muscle strength. Pelvic floor muscle strength was measured with the woman in the lithotomy position using a Peritron 9300 V perineometer. Data were analyzed using one-way analysis of variance, the least significant difference test and the chi-squared test.
The nulliparous women had the highest mean pelvic muscle strength (55.62 ± 15.86 cm HO). Women who had vaginal delivery with episiotomy had the lowest pelvic muscle strength (32.71 ± 14 cm HO). In nulliparous women pelvic floor muscle strength was higher than in women who had normal vaginal delivery with episiotomy (p < 0.001), but was not significantly different from that in women with normal vaginal delivery without episiotomy or in women with cesarean section (elective or emergency, p = 0.245).
Nulliparous women had the highest pelvic floor muscle strength and there was no significant difference in pelvic floor muscle strength between women with normal vaginal delivery and those with cesarean section.
盆底功能薄弱在女性中相当常见，且可能在分娩后出现。本研究的目的是比较未生育、剖宫产或顺产的育龄女性的盆底肌肉力量。
在这项横断面研究中，从伊朗阿瓦士的公共卫生中心随机招募了341名女性，包括96名未生育女性、73名有顺产史（有或无会阴切开术）的女性以及172名有择期或急诊剖宫产史的女性。使用社会人口统计学调查问卷收集数据，并使用清单记录体重、身高、体重指数和盆底肌肉力量。让女性处于截石位，使用Peritron 9300 V会阴测量仪测量盆底肌肉力量。采用单因素方差分析、最小显著差检验和卡方检验对数据进行分析。
未生育女性的平均盆底肌肉力量最高（55.62±15.86 cm H₂O）。有会阴切开术的顺产女性的盆底肌肉力量最低（32.71±14 cm H₂O）。未生育女性的盆底肌肉力量高于有会阴切开术的顺产女性（p<0.001），但与无会阴切开术的顺产女性或剖宫产女性（择期或急诊，p=0.245）相比无显著差异。
未生育女性的盆底肌肉力量最高，顺产女性和剖宫产女性的盆底肌肉力量无显著差异。
