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.
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.
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.
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.
本研究旨在：(1) 探讨妊娠相关腰痛的位置是否会影响日常生活活动和缺勤；(2) 确定哪些类型的疼痛更有可能在产后持续存在。
这是一项观察性队列研究数据的二次分析。数据于 2013 年至 2014 年在安大略省收集。确定了 4 种疼痛位置组，包括下腰痛（LBP）、骨盆带疼痛（PGP）、联合疼痛和混合疼痛。使用逻辑回归模型来检查疼痛位置对活动和缺勤的影响。描述性分析探讨了妊娠疼痛位置与产后疼痛模式之间的关系。
我们调查了 305 名孕妇，并对其中 80 名进行了随访，直到产后 6 个月。数据分析显示，与仅出现 LBP 的孕妇相比，出现联合疼痛的孕妇在工作（外出）和自我护理方面的干扰大约增加了两倍。出现 PGP 和联合 PGP 和 LBP 的孕妇与仅出现 LBP 的孕妇相比，缺勤的可能性增加了大约 5 倍；出现 LBP 和 PGP 混合的孕妇的可能性增加了 13 倍。大约 50%的受访者报告无疼痛，16%的受访者报告有持续疼痛，38%的受访者在产后 6 个月内出现持续疼痛。在怀孕期间出现联合疼痛的受访者在产后 6 个月内仍有持续疼痛。
结果表明，妊娠相关腰痛的位置与日常生活活动的干扰、缺勤的增加以及产后疼痛的持续存在有关。对于这一队列，背部疼痛在分娩后并不总是缓解，那些经历妊娠相关联合疼痛的人在产后仍会出现症状。
