The purpose of this study was to examine the relationship between maternal work and infant feeding practices and explore the moderating impact of parental stress.
Prospective data on categorical hours worked and infant feeding practices were collected at 3 and 6 months postpartum in a prospective prenatal cohort of 95 women. Chi-square tests were used to compare change in proportion of exclusive breastfeeding from birth to 6 months and maternal work status.
Rates of exclusive breastfeeding significantly decreased from birth to 6 months, while the percent of mothers working outside of the home significantly increased from 3 to 6 months. At 6 months, mothers who worked full time pumped significantly more than their non-working counterparts. Multivariate logistic regression models were used to test the prediction of exclusive breastfeeding by maternal work, including sociodemographic covariates, and the moderating impact of parental stress. Results indicated that maternal education, paternal education, and maternal work significantly predicted exclusive breastfeeding at 6 months. Full time work (OR = 0.09, 95% CI = 0.01, 0.62) was associated with a decreased odds of exclusive breastfeeding. Additionally, higher maternal (OR = 1.44, 95% CI = 1.05, 1.97) and paternal (OR = 1.28, 95% CI = 1.00, 1.66) education was associated with an increased odds of exclusive breastfeeding. Maternal stress did not predict exclusive breastfeeding, nor did it have a moderating effect on the relationship between maternal work and breastfeeding.
Future studies should investigate maternal work in more diverse birthing populations to better understand how families can incorporate breastfeeding as a primary infant feeding practice.
本研究旨在探讨母亲工作与婴儿喂养方式之间的关系，并探讨父母压力的调节作用。
在一项前瞻性产前队列研究中，于产后 3 个月和 6 个月收集了 95 名女性的分类工作时间和婴儿喂养方式的前瞻性数据。卡方检验用于比较从出生到 6 个月时纯母乳喂养比例的变化和母亲的工作状态。
纯母乳喂养的比例从出生到 6 个月显著下降，而外出工作的母亲比例从 3 个月到 6 个月显著增加。在 6 个月时，全职工作的母亲泵奶量明显多于不工作的母亲。多变量逻辑回归模型用于测试母亲工作对纯母乳喂养的预测，包括社会人口统计学协变量和父母压力的调节作用。结果表明，母亲教育、父亲教育和母亲工作显著预测了 6 个月时的纯母乳喂养。全职工作（OR=0.09，95%CI=0.01，0.62）与纯母乳喂养的可能性降低相关。此外，母亲（OR=1.44，95%CI=1.05，1.97）和父亲（OR=1.28，95%CI=1.00，1.66）的教育程度较高与纯母乳喂养的可能性增加相关。母亲压力既不能预测纯母乳喂养，也不能调节母亲工作与母乳喂养之间的关系。
未来的研究应该在更多样化的分娩人群中研究母亲工作，以更好地了解家庭如何将母乳喂养作为主要的婴儿喂养方式。
