Prevalence and factors associated with postpartum pelvic girdle pain among women in Poland: a prospective, observational study.

Pelvic girdle pain (PGP) is a type of pregnancy-related lumbopelvic pain. This study aimed to examine the prevalence, severity, and factors associated with postpartum PGP in a selected group of postpartum women in Poland. This was a prospective, observational study. In phase 1, 411 women were recruited 24-72 h postpartum. The prevalence of PGP was assessed by a physiotherapist using a series of dedicated tests. Pelvic floor muscle function and presence of diastasis recti were assessed via palpation examination. Age, education, parity, mode of delivery, infant body mass, body mass gain during pregnancy, the use of anesthesia during delivery and were recorded. In a phase 2, 6 weeks postpartum, the prevalence of PGP and its severity were assessed via a self-report. In phase 1 (shortly postpartum), PGP was diagnosed in 9% (n = 37) of women. In phase 2 (6 weeks postpartum), PGP was reported by 15.70% of women (n = 42). The univariable analyses showed a higher likelihood of PGP shortly postpartum in women who declared PGP during pregnancy (OR 14.67, 95% CI 4.43-48.61) and among women with abdominal midline doming (OR 2.05, 95% CI 1.04-4.06). The multivariable regression analysis showed significant associations in women with increased age (OR 1.12, 95% CI 1.01-1.21) and declaring PGP during pregnancy (OR 14.83, 95% CI 4.34-48.72). Although the prevalence of postpartum PGP among women in Poland is lower than reported in other countries, it is experienced by almost every tenth women shortly postpartum and every sixth can report similar symptoms 6 weeks later. Age, PGP during pregnancy and abdominal midline doming were associated with experiencing PGP shortly postpartum.
