Abstract

Objective

Evaluating the changes of the perineal muscles in primigravid women with obesity (BMI ≥ 30) and to compare the progress with primigravid women in normal BMI range.

Methods

A prospective longitudinal cohort study was carried out. The pregnant women were studied at three moments: at 12 weeks’ gestation, at 34 weeks’ gestation and at 12 weeks after delivery. During the ckeck-up, perinometric measurements were taken to determine basal tone (BT), maximum contractile force (FMax) and applied forced (AF). In addition, the Oxford test (MOS) was used. General statistical mixed models were used for the statistical study.

Results

Fifty nulliparous pregnant women (25 with BMI ≥ 30 and 25 with BMI < 25) were recruited at the beginning of the study and 39 completed the entire study. Basal tone (BT) was 4.62 ± 0.24 Nw at the beginning of pregnancy and decreased to 4.18 ± 0.26 Nw after delivery. Contractile capacity was 5.56 ± 0.79 Nw at week 12 and increased to 6.34 ± 1.24 Nw after delivery. When comparing the FCMax at week 12 in obese vs. normal weight pregnant women, values of 5.51 ± 87 Nw vs. 5.61 ± 0.71 Nw were observed (P=.941). Postpartum values were 6.72 ± 1.17 Nw vs. 5.95 ± 1.21 Nw (P=.024), higher in the obese population.

Conclusions

There is an increase in contractile strength (Fmax) at 12 weeks postpartum in order to counteract the significant decrease in basal tone (BT). The body has compensatory mechanisms that allow recovery after 3 months postpartum, with greater muscle strength in obese patients.

我们的研究结果表明，在怀孕和分娩期间，肥胖女性会阴部肌肉组织的变化。纵向队列研究

评估肥胖女性(体重指数[bmi]≥30)会阴肌肉组织的演变，并与bmi在正常体重范围内的女性进行比较。我们进行了一项前瞻性纵向队列研究，对孕妇进行了3个阶段的研究:妊娠12周、妊娠34周和分娩后12周。在这些会诊中，通过围产期测量来确定基线张力(TB)、最大收缩力(FMax);以及所施加的力量(信仰)。此外，还使用了改进的牛津测试(MOS)。统计研究混合一般采用统计模型。在开始时招募了50名未产孕妇(25名bmi≥30,25名bmi < 25)，完成了完整的研究39。妊娠初期会阴基底张力为4.62±0.24牛顿(Nw)，产后降至4.18±0.26牛顿(Nw)。第12周收缩能力为5.56±0.79 Nw，产后收缩能力为6.34±1.24 Nw。比较肥胖孕妇和正常体重孕妇第12周的最大hrmax值为5.51±87 Nw和5.61±0.71 Nw (p = 0.941)。产后值为6.72±1.17 Nw vs. 5.95±1.21 Nw (p = 0.024)，肥胖人群较高。在产后12周，基底张力显著下降，可被可测量的收缩力增加所抵消。身体有补偿机制，允许从产后3个月开始恢复，肥胖患者的肌肉力量更大。评估肥胖女性(BMI≥30)会阴肌肉的变化，并与BMI正常范围的女性进行比较。进行了一项前瞻性纵向队列研究。= =地理= =根据美国人口普查，这个县的面积为，其中土地和(1.1%)水。在拍摄过程中，进行了周周测量，以确定基础音(BT)、最大收缩力(FMax)和施加力(AF)。= =地理= =根据美国人口普查局的数据，这个城镇的土地面积为，其中土地和(1.)水。= =地理= =根据美国人口普查局的数据，该镇总面积为，其中土地和(1.5%)水。50名无残疾孕妇(25名BMI≥30,25名BMI < 25)在研究开始时被招募，39名完成了整个研究。的音调(BT) was 4.62±0.24 Nw at the beginning of怀孕and decreased to 4.18±0.26 Nw after delivery。= =地理= =根据美国人口普查，该镇的总面积为，其中土地和(0.9%)水。比较肥胖孕妇与正常体重孕妇在第12周的hrmax值为5.51±87 Nw vs. 5.61±0.71 Nw (P=.941)。产后值为6.72±1.17 Nw vs. 5.95±1.21 Nw (P= 0.024)，肥胖人群较高。在分娩后12周收缩强度(Fmax)增加，以对抗基底音(BT)的显著下降。你compensatory机制that The body allow recovery after 3月postpartum with greater如果我是法官in obese patients。

期刊介绍： Enfermería Clínica is a peer-reviewed scientific journal that is a useful and necessary tool for nursing professionals from the different areas of nursing (healthcare, administration, education and research) as well as for healthcare professionals involved in caring for persons, families and the community. It is the only Spanish nursing journal that mainly publishes original research. The aim of the Journal is to promote increased knowledge through the publication of original research and other studies that may help nursing professionals improve their daily practice. This objective is pursued throughout the different sections that comprise the Journal: Original Articles and Short Original Articles, Special Articles, Patient Care and Letters to the Editor. There is also an Evidence-Based Nursing section that includes comments about original articles of special interest written by experts.
