Purpose
Persistent low back and pelvic pain (LBPP) is a postpartum-specific health problem. Sleep disturbances’ association with persistent LBPP is not yet clear. We aimed to examine the cross-sectional association between sleep disturbance and persistent LBPP at 4 months postpartum.
Methods
We enrolled 120 women with LBPP during pregnancy (mean age, 31.8; standard deviation, 4.9 years). The primary outcome was persistent LBPP. We assessed LBPP severity at 4 months postpartum using the Numerical Rating Scale (NRS), where women with an NRS score of ≥ 4 at 4 months postpartum were allocated to the persistent LBPP group. We assessed sleep disturbance at 4 months postpartum using the Japanese version of the Pittsburgh Sleep Quality Index with a total score of ≥ 6 indicating sleep disturbance. Moreover, we performed univariate and multiple logistic regression analyses to examine the cross-sectional association of sleep disturbance with persistent LBPP. The relevant confounding variables were age, body mass index, parity, and history of LBPP before pregnancy.
Results
Among the 120 women, 45 women had persistent LBPP (37.5%) with 32 (71.1%) of them reporting sleep disturbance. There was a significant association of sleep disturbance with persistent LBPP (odds ratio [OR], 2.81; 95% confidence interval [95% CI], 1.28–6.19), which remained after adjustments for confounding variables (OR, 2.98; 95% CI, 1.31–6.75).
Conclusion
Our findings indicate that sleep disturbance is associated with persistent LBPP at 4 months postpartum; therefore, it should be taken into consideration in postpartum women with persistent LBPP.
