Correlation between maternal eating disorder and early infant feeding regulation: a cross -sectional study

BACKGROUND: The post-partum period is a vulnerable time for mothers in terms of eating disorder symptoms and is critical for the establishment of feeding patterns in infants. This study aimed to investigate the relationships between maternal eating disorder symptoms and objective indices of feeding regulation at 3 months, as well as perceived breastfeeding self-efficacy. METHODS: A sample of n = 73 full-term mother-child dyads (44% female) participated in the study. Mothers self-reported eating disorder symptoms and breastfeeding self-efficacy and objective indices of infant feeding regulation were obtained in the home. RESULTS: Findings revealed the existence of relationships between higher maternal eating disorder symptoms, and objective indices of infant feeding regulation with substantial gender differences in the patterns emerging. Among mother-daughter dyads, maternal weight and shape concerns were associated with higher infant transfer volume and rate during bottle feeding. In contrast, among mother-son dyads, higher maternal eating disorder symptoms, including weight, shape, and eating concern, were associated with lower infant transfer volume and rate as well as lower levels of proficiency while taking their bottle. CONCLUSION: Relationships emerged between higher maternal eating disorder symptoms and feeding regulation with substantial gender differences in these patterns. Additional research clarifying the underlying mechanisms of these associations is warranted and further efforts should be directed towards supporting mothers during the postpartum period.
