SUMMARY
Effect of breast feeding an psychosocial variables upon psychomotor development of 12 months old infants
This study evaluates the participation of psychosocial variables in the relation between breast feeding (BF) and psychomotor development (PMD) in dyads with different BF duration. Weassessed 138 mother- infant dyads, divided in two groups: 86 received BF as unique source of milk feeding for at least 6 months (prolonged BF group) and 52 were weaned before 45 days of age (early weaning group). General information about pregnancy, delivery and feeding was collected in a non experimental prospective designo At 6-7 months of age a milk feeding situation was observed at home, and mother-infant interactional patterns were recorded through a specially designed scale. At 12 months of age the PMD was assessed (Bayley Scales of Infant Development). Infant temperament, borne stimulation, mother depression and family stress were also measured. Similar family characteristics were observed in both study groups. Early bonding and first feeding experiences were different. both reported as better in the prolonged BF group. Moreover, dyads of this group showed a higher variety and quality of mother-infant interactional patterns during feeding, with a higher synchrony and reciprocity in the relationship. Mean Mental Development Index (MDI) and Psychomotor Developmental Index (PDI) were similar in both groups. Explicatory variables for MDI and PDI are different in both study groups. Dyads who attained prolonged BF conform from a psychosocial perspective- a different group than the early weaned.
Key words: Breast feeding, psychomotor development, mother- infant interaction, feeding.
