A substantial number of women have postpartum lumbopelvic pain (LBPP). Additionally, many postpartum women stay for long inactivity. Therefore, we examined the impact of sedentary behavior on persistent postpartum LBPP and the difference in this impact due to parity. This cohort study followed up women who had reported LBPP at 4 months postpartum and divided them into the presence or absence of LBPP at 10 months postpartum. Sedentary time and physical activity were assessed at 4 months postpartum using the International Physical Activity Questionnaire short form. Univariate and multivariate logistic regression analysis was used to calculate persistent LBPP odds ratios (ORs) according to sedentary times, followed by stratification analysis by parity. The institutional review board approval was obtained. A total of 182 women (32.1 ± 5.1 years old) were included for analysis and 112 (61.5%) participants had persistent LBPP at 10 months postpartum. Those with persistent LBPP at 10 months postpartum had increased sedentary time (5.0 [3.0-7.0] hours vs. 3.5 [2.0-6.0] hours, = 0.05) at 4 months compared with those without LBPP. Even after adjusting for confounding factors, longer sedentary time at 4 months postpartum affected persistent LBPP at 10 months postpartum in primiparas (adjusted OR [95% confidence interval, CI] = 1.28 [1.05-1.55]), but longer sedentary time at 4 months postpartum did not affect persistent LBPP at 10 months postpartum in multiparas (adjusted OR [95% CI] = 0.96 [0.86-1.07]). Sedentary behavior after childbirth is associated with persistent postpartum LBPP in primiparas, but not multiparas. Reducing sedentary time might be beneficial to prevent persistent postpartum LBPP for primiparas.
大量女性在产后会出现腰骶部疼痛（LBPP）。此外，许多产后女性会长期处于不活动状态。因此，我们研究了久坐行为对产后持续 LBPP 的影响，以及因产次不同而导致的这种影响的差异。这项队列研究随访了在产后 4 个月报告有 LBPP 的女性，并将她们分为在产后 10 个月时是否仍有 LBPP。在产后 4 个月使用国际体力活动问卷短表评估久坐时间和体力活动。使用单变量和多变量逻辑回归分析，根据久坐时间计算持续 LBPP 的比值比（OR），然后按产次进行分层分析。该研究获得了机构审查委员会的批准。共纳入 182 名女性（32.1±5.1 岁）进行分析，112 名（61.5%）参与者在产后 10 个月时仍有 LBPP。与没有 LBPP 的参与者相比，在产后 10 个月仍有 LBPP 的参与者在产后 4 个月时的久坐时间更长（5.0[3.0-7.0]小时 vs. 3.5[2.0-6.0]小时，=0.05）。即使在校正了混杂因素后，在初产妇中，产后 4 个月的久坐时间与产后 10 个月的持续 LBPP 相关（校正后的 OR[95%置信区间，CI]为 1.28[1.05-1.55]），但在经产妇中，产后 4 个月的久坐时间与产后 10 个月的持续 LBPP 无关（校正后的 OR[95%CI]为 0.96[0.86-1.07]）。产后久坐行为与初产妇持续产后 LBPP 相关，但与经产妇无关。减少久坐时间可能有益于预防初产妇持续产后 LBPP。
