ABSTRACT
BACKGROUND: Despite scientific recommendations for exclusive breastfeeding until 6 months of age and complementary breastfeeding to 2 years of age, breastfeeding abandonment rates increase with time, and one of the main reasons is that women go back to work. AIM: To analyze the perception of support of breastfeeding workers to continue breastfeeding at two Spanish universities, and associated factors. METHODS: A multicenter retrospective cross-sectional comparative study conducted in a population of 777 female workers at the Universidad de Sevilla (US) and the Universitat Jaume I (UJI) in Spain using an online questionnaire. RESULTS: The response rate was 38.74% (n = 301). Of all the participants, 57.8% continued breastfeeding after returning to work. The factors associated with continuing breastfeeding for longer were the university having a breastfeeding support policy and special accommodation (p < 0.001); participating in breastfeeding support groups (p < 0.001); intending to continue breastfeeding after returning to work (p < 0.001); knowing the occupational legislation in force (p = 0.009); having a female supervisor (p = 0.04). CONCLUSION: Breastfeeding support initiatives and having special accommodation to pump and preserve breast milk after returning to work are associated with a longer duration of female workers' breastfeeding.
