Evaluation of lactation support in the workplace or school environment on 6-month breastfeeding outcomes in Yolo County, California.

Six-month breastfeeding outcomes (almost exclusive breastfeeding, partial breastfeeding, and not breastfeeding) were analyzed for 201 infants born to Yolo County, California, mothers who returned to work or school. Twenty-two percent of workplaces and 17% of schools did not provide a lactation room. Although part- or full-time status, knowledge of breastfeeding rules, and support from colleagues were independently associated with the outcome, they were not significant in the multivariate analysis. In the selected model, maternal age (odds ratio [OR] = 2.3; 1.3-3.9 for a 10-year difference), college or above versus <or= high school education (OR = 9.1; 4.2-19.6), and exclusive breast milk feeding in the hospital (OR = 2.1; 1.1-4.0) were associated with better breastfeeding outcomes at 6 months postpartum. Receipt of discharge gift packs containing formula (OR = 0.5; 0.3-1.0) was inversely associated with the degree of breastfeeding exclusivity. The 2 latter findings underscore the importance of hospitals adhering to specific guidelines of the Baby-Friendly Hospital Initiative.
