Objective: The aims of this study were to (1) examine if the location of pregnancy-related back pain impacts activities of daily living and absence from work and (2) determine which types of pain were more likely to persist postpartum.

Methods: This was a secondary analysis of data from an observational cohort study. Data were collected in Ontario between 2013 and 2014. Four pain location groups were identified, including low back pain (LBP), pelvic girdle pain (PGP), combined pain, and mixed pain. Logistic regression models were used to examine the impact of pain location on activity and absence from work. Descriptive analyses explored the association between pregnancy pain location and postpartum pain patterns.

Results: We surveyed 305 pregnant participants and followed up with 80 of these participants up to 6 months postpartum. Data analysis showed approximately a 2-fold increase in interference with employment (outside the home) and self-grooming for those with combined pain compared to those only experiencing LBP. Respondents with PGP and combined PGP and LBP had approximately a 5-fold increased likelihood of absence from work compared to respondents with only LBP; those with a mixture of LBP and PGP had a 13-fold increase in likelihood. Approximately 50% of respondents reported being pain-free, 16% experienced lingering pain, and 38% experienced persistent pain within 6 months postpartum. Those with combined pain during pregnancy continued to have persistent pain up to 6 months postpartum.

Conclusion: The results suggest that the location of pregnancy-related back pain is associated with interference in daily activities, an increase in absence from work, and the persistence of postpartum pain. For this cohort, back pain did not always resolve after delivery, and those experiencing pregnancy-related combined pain continued to experience symptoms postpartum.
