Objective
To test the effects of kangaroo care (KC) on breastfeeding outcomes in preterm infants compared to two control groups and to explore whether maternal-infant characteristics and the mother’s choice to use KC were related to breastfeeding measures.
Design
Secondary analysis of a multisite, stratified, and randomized 3-arm trial. The treatment groups used KC, auditory-tactile-visual-vestibular (ATVV) intervention, or preterm infant care information.
Setting
Neonatal intensive care units from 4 hospitals in the United States from 2006–2011.
Participants
Racially diverse mothers (N=231) and their preterm infants born weighing < 1750 grams.
Methods
Mothers and their infants were enrolled once the infants were no longer critically ill, weighed at least 1000 grams, and could be safely held outside of the incubator by parents. Participants were instructed by study nurses; those allocated to either KC or ATVV were asked to engage in these interactions for a minimum of 3 times a week in the hospital and at home until 2 months adjusted age.
Results
Feeding at the breast during hospitalization, the duration of post-discharge breastfeeding, and breastfeeding exclusivity after hospital discharge did not differ statistically among the treatment groups. Regardless of group assignment, married, older, and more educated women were more likely to feed at the breast during hospitalization. Mothers who practiced KC, regardless of randomly allocated group, were more likely to provide their milk than those who did not practice KC. Breastfeeding duration was greatest among more educated women.
Conclusion
As implemented in this study, assignment to KC did not appear to influence the measured breastfeeding outcomes.
