Background and/or Objectives: Many women experience low back pain (LBP) at some point in their pregnancy. There are physiologic changes of pregnancy that contribute to LBP. It is often viewed as a normal part of pregnancy resulting in under-treatment. We assessed the association between demographic characteristics and likelihood of documented LBP diagnosis/referral for specialty treatment.

Design: We performed a retrospective cohort study using Health Data Compass data of subjects over a 5-year period (2015-2019).

Setting: A tertiary care center.

Participants: Subjects were 23,043 pregnant women aged 12-55 who established care at least 90 days prior to delivery.

Interventions: not applicable

Main Outcome Measures: LBP diagnosis, back pain type, specialty referral , referral department.

Results: 14.6% of subjects had LBP diagnosis (95% confidence interval [CI]: 14.1%, 15.1%). While women were 11% less likely (95% CI: -13%, -8%) to have a documented LBP diagnosis for each 5-year increase in age, they were 21% more likely (95% CI: 12%, 30%) to be referred for specialty treatment for each 5-year increase in age. Hispanic women were 15% more likely to be diagnosed (95% CI: 7%, 24%) than women of all other ethnicities, but were 20% less likely to be referred (95% CI: -37%, 0%). Compared to White women, Black women were 48% more likely to be diagnosed (95% CI: 35%, 64%), while Asian women were 25% less likely to be diagnosed (95% CI: -39%, -7%). Axial and neurogenic LBP were more likely to be referred to rehabilitation services including physical therapy and integrative medicine modalities. Sacrococcygeal and cervical/thoracic back pain were more likely to be referred to rehabilitation medicine (physical medicine & rehabilitation, spine, and pain medicine).

Conclusions: A small percent of women with diagnosed LBP during pregnancy were referred. There were discrepancies amongst referral and diagnosis in demographic domains. Sacrococcygeal and cervical/thoracic back pain were referred to different services than axial and neurogenic LBP.
