Purpose: This study was to identify relationships of maternal psychosocial factors including mother's mood state,childcare stress, social support and sleep satisfaction with breastfeeding adaptation and immune substances inbreast milk, especially secretory immunoglobulin A (sIgA) and transforming growth factor-beta 2 (TGF-β2). Methods:Data were collected from 84 mothers who delivered full-term infants by natural childbirth. Structured questionnairesand breast milk were collected at 2~4 days and 6 weeks postpartum. Data were analyzed using descriptive statistics,Pearson's correlation, multiple linear regression, and generalized estimating equation (GEE). Results: Scores forthe breastfeeding adaptation scale were significantly related with child care stress, mood state and social support. Mother’s anger was positively correlated with the level of sIgA in colostrum (p<.01). Immune substances of breastmilkwas significantly influenced by time for milk collection (p<.001) and the type of breastfeeding (sIgA, p<.001,TGF-β2, p=.003). Regression analysis showed that breastfeeding adaptation could be explained 59.1% by the typeof breastfeeding, childcare stress, the Profile of Mood States, emotional support and sleep quality (F=16.67, p<.001). Conclusion: The findings from this study provide important concepts of breastfeeding adaptation program and explanationof psychosocial factors by immune substances in breast milk. Future research, specially, bio-maker researchon breast milk should focus on the ways to improve breastfeeding adaptation. Key Words: Breastfeeding, Human milk, Adaptive behavior, Immunologic factors, Psychosocial factors
