Low Back Pain during Pregnancy and Delivery Outcomes

Aim To evaluate low back pain (LBP) incidence and impact throughout pregnancy in terms of women’s well-being and delivery outcomes. Material and methods Cross-sectional prospective study conducted on singleton pregnancies at ≥37th gestational age admitted for delivery. Localization of LBP, intensity and frequency as well as derived functional disability status were assessed with a self-reported questionnaire. Main delivery outcomes including mode of delivery, and maternal or neonatal complications were recorded. Results A total of 229 women participated in the study. LBP prevalence amounted to 55.9%, with the pain already present before pregnancy in 14.0% of the cases. The pain was mostly localized in the lower back (40.6%), symphysis (23.3%), and coccyx (20.5%). Both the frequency and intensity of pain gradually increased significantly during pregnancy, reaching 20 days/month (IQR=10–30) and 6/10 points (IQR=5–8) on a visual analog scale in the 3rd trimester (p Conclusions LBP is a common issue in pregnant women, accounting for increasing morbidity and invalidity, and leading to an increased cesarean section risk during labor.
