摘要
To examine the associations between breastfeeding intensity and underexplored features of maternal-child interaction quality over and above the influence of breastfeeding initiation.The current study leveraged an on-going, multisite randomized controlled trial of a tiered parenting program for 462 Medicaid-eligible mothers and their infants in the United States. We examined whether breastfeeding intensity and exclusivity was associated with observed maternal sensitivity, intrusiveness, and detachment, as well as self-reported maternal verbal responsiveness, 6 months infant age. Analyses controlled for breastfeeding initiation, demographics, and early parenting experiences.Higher intensity breastfeeding at 6 months was significantly related to higher maternal sensitivity (β = 0.12, p = 0.004) and lower maternal intrusiveness (β = -0.10, p = 0.045). There was no significant association between breastfeeding intensity at 6 months and detachment (β = -0.02, no significant [ns]) or self-reported verbal responsiveness (β = 0.11, ns). Results were the same when intensity was measured as a dichotomous indicator for exclusive breastfeeding. Effect sizes were small-to-moderate, ranging from Cohen's d = 0.26 to 0.31. Associations did not vary by site, race/ethnicity, infant difficultness, or household poverty.The finding that breastfeeding intensity was significantly and independently associated with maternal sensitivity and intrusiveness is novel in the literature on low-income families from the United States. These findings have implications for breastfeeding promotion strategies and indicate that future research should explore synergistic or spillover effects of interventions aimed at maternal-child interaction quality into the infant feeding domain, particularly in the primary care setting.
