近年来，产妇就业率迅速上升，但人们对这如何影响妇女是否开始母乳喂养知之甚少。我们检查了千年队列研究的数据，以确定母亲的就业状况（全职，兼职，自营职业者，休假，不就业/学生）和就业特征是否与母乳喂养开始有关。这项分析包括来自英国和爱尔兰的14830名白色母亲（6917名就业人员），他们在2000年至2002年期间出生了独生子女。当婴儿9个月大时，我们获得了婴儿喂养史和母亲就业的信息。我们发现，全职工作的妇女比没有工作的母亲/学生开始母乳喂养的可能性更小，调整混杂因素后[调整率比（aRR）= 0.92; 95%置信区间（CI）0.89，0.96];然而，在开始母乳喂养方面，从事非全时工作、自营职业或休假的母亲与没有工作/学生的母亲之间没有差别。在有工作的母亲中，产后4个月内返回工作岗位的妇女开始母乳喂养的可能性低于产后5或6个月返回工作岗位的妇女[aRR = 0.95; 95%CI 0.92，0.99]，在产后前6周内返回工作岗位的妇女开始母乳喂养的可能性要低得多[aRR = 0.85; 95%CI 0.77，0.94]。与因其他原因返回的母亲相比，因经济原因返回的母亲也不太可能开始母乳喂养[aRR = 0.96; 95%CI 0.93，0.99]。增加母乳喂养的政策应解决母亲产后重返工作岗位的时间和情况如何影响她是否决定开始母乳喂养的问题。
Maternal employment rates have increased rapidly in recent years and little is known about how this influences whether women start breast feeding. We examined data from the Millennium Cohort Study to determine whether a mother's employment status (full-time, part-time, self-employed, on leave, not employed/student) and employment characteristics are related to breast-feeding initiation. This analysis comprised 14 830 white mothers from Britain and Ireland (6917 employed) with singleton babies, born from 2000 to 2002. Information was obtained on infant feeding history and mother's employment when the cohort child was 9 months old.We found that women employed full-time were less likely to initiate breast feeding than mothers who were not employed/students, after adjustment for confounding factors [adjusted rate ratio (aRR) = 0.92; 95% confidence interval (CI) 0.89, 0.96]; however, there were no differences in breast-feeding initiation between mothers employed part-time, self-employed, or on leave and mothers who were not employed/students. Among employed mothers, those who returned to work within 4 months postpartum were less likely to start breast feeding than women who returned at 5 or 6 months [aRR = 0.95; 95% CI 0.92, 0.99], and women who returned within the first 6 weeks were much less likely to start breast feeding [aRR = 0.85; 95% CI 0.77, 0.94]. Mothers returning for financial reasons were also less likely to initiate breast feeding [aRR = 0.96; 95% CI 0.93, 0.99] than those who returned for other reasons. Policies to increase breast feeding should address how both the time and circumstances of a mother's return to employment postpartum influence whether she decides to start breast feeding.
