Return to work is often cited as a reason for early cessation of breastfeeding (BF). Our objectives were to study the time span during which women employed prior to pregnancy returned to work according to BF duration category, and to identify sociodemographic, behavioral and pregnancy characteristics of women who continued BF after returning to work.
Information on BF mode and work status was prospectively collected in a French nation-wide birth cohort up to 1 year after delivery. Time of return to work according to BF category was addressed using Kaplan-Meier curves and Poisson regression adjusted on co-variates. Multiple logistic regression enabled to identify characteristics associated with the combination of BF with work.
Among 2480 women holding jobs prior to pregnancy, 82.0% returned to work within a year postpartum. Women who breastfed > 4 months returned at median of 6.5 months, whereas those who did not breastfeed at all returned to their jobs at 4.0 months, those who had breastfed for less than 1 month returned at 4.5 months, and those who had breastfed for 1 to 4 months returned at 4.0 months. Around one-third of women (34.5%) combined BF and work, and breastfed for a longer duration (median: 213 days, vs. 61 days for women who stopped BF before returning to work). Women born outside of France or who were self-employed were more likely to combine BF and work, while intermediate employees, manual workers, women who quitted smoking during pregnancy, who had smoked before and during pregnancy, or who had given birth by cesarean section were less likely to combine BF and work.
Women who had breastfed for less than 4 months, or not at all, returned to their jobs at comparable times. This suggests that working women should be encouraged to breastfeed, even for a short duration. Moreover, only one-third of working women succeeded in combining BF and work, highlighting the need for a support system that would encourage flexibility.
重返工作岗位常被认为是早期停止母乳喂养(BF)的原因之一。我们的目的是研究在怀孕前就业的女性根据 BF 持续时间分类返回工作岗位的时间跨度,并确定在返回工作岗位后继续 BF 的女性的社会人口学、行为和妊娠特征。
在法国全国性的出生队列中,前瞻性地收集了产后 1 年内 BF 模式和工作状况的信息。使用 Kaplan-Meier 曲线和调整协变量的泊松回归来解决 BF 类别与工作的时间关系。多因素逻辑回归用于确定与 BF 与工作相结合相关的特征。
在 2480 名怀孕前有工作的女性中,82.0%的人在产后一年内返回工作岗位。母乳喂养时间超过 4 个月的女性中位数在 6.5 个月时返回工作岗位,而完全不母乳喂养的女性在 4.0 个月时返回工作岗位,母乳喂养时间少于 1 个月的女性在 4.5 个月时返回工作岗位,母乳喂养时间为 1 至 4 个月的女性在 4.0 个月时返回工作岗位。约三分之一的女性(34.5%)将 BF 和工作相结合,并且母乳喂养时间更长(中位数:213 天,而对于在返回工作前停止 BF 的女性为 61 天)。在法国境外出生或自营职业的女性更有可能将 BF 和工作结合起来,而中等收入员工、体力劳动者、在怀孕期间戒烟、在怀孕期间吸烟或经剖宫产分娩的女性则不太可能将 BF 和工作结合起来。
母乳喂养时间少于 4 个月或根本没有母乳喂养的女性在相近的时间返回工作岗位。这表明,应该鼓励工作女性进行母乳喂养,即使是短时间的母乳喂养。此外,只有三分之一的工作女性成功地将 BF 和工作结合起来,这突显了需要一个支持系统来鼓励灵活性。
