研究问题
The current research explores whether childbirth type, the number of pregnancies, and natural aging correlate with PFMS in healthy, continent women.
方法
After the Research Ethics Committee of the Medical School of Botucatu Hospital approved the study under protocol number 61/07 and all subjects signed an informed consent form, healthy women were prospectively evaluated in a cross-sectional study.；Inclusion criteria: no urological complaints or clinical metabolic or reproductive diseases.；Exclusion criteria: comorbidity, medication use, incontinence, and complications that occurred during a delivery.；Demographic data, including age, body mass index (BMI), level of physical activity, and the number and type of childbirths, were collected using a clinical questionnaire [].
核心结论
BMI was significantly higher in Group 4 (G4) compared to Group 1 (G1) (27.9 ± 3.6 vs. 24.9 ± 4.1; p = 0.040).；There were no significant differences in BMI among the other groups.；We also found a positive linear relationship between age and BMI (r = 0.215; p = 0.011). ‖ 结论：Multicenter prospective studies including more diverse populations are warranted to confirm these results, and standardized multimodal obstetric documentation and imaging assessments before and after delivery are needed for a holistic and accurate understanding of PFMS, particularly in complex or incongruent cases [].
局限
Brazil’s unique mix of Indigenous, African, and European ancestry presents a distinct population whose risk factors, disease presentation, and treatment response may not align with findings from more homogeneous populations.；Moreover, research in healthy cohort controls for confounding variables such as comorbidities, prior surgeries, and medication use, enabling clearer interpretation of muscle function data.；This suggests that well-assisted vaginal delivery may not necessarily compromise the PFMS in healthy, continent women.

本文属人体研究证据，但需注意：观察性或小样本干预的结论不等于已证实临床获益；效应量与长期安全性仍需更大规模、更长随访的试验验证。
