Maternal Work and Infant Feeding Practices in the First 6 Months.

Abstract

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.
