Maternal Personality and Psychosocial Variables Associated with Initiation Compared to Maintenance of Breastfeeding: A Study in Low Obstetric Risk Women.

INTRODUCTION: The benefits of breastfeeding are well known for mother and child. Research about the predictive factors related to the initiation and maintenance of breastfeeding is of great interest to public health.

AIM: To analyze the factors associated with the timely initiation of breastfeeding at immediate postpartum and the variables that facilitate their maintenance 4 months after birth.

MATERIALS AND METHODS: A longitudinal prospective design was used, including four stages: first trimester of pregnancy (personality), third trimester (childbirth expectations, breastfeeding intention, pregnancy worries, and coping strategies), immediately after childbirth (initiation of breastfeeding and childbirth satisfaction), and 4 months after birth (continuation of breastfeeding).

RESULTS: A sample of 116 women took part in the study from the first trimester to 4 months after birth. Timely initiation of breastfeeding is associated with vaginal birth (p < 0.000) and with variables related to the absence of stress factors: fewer worries regarding childbirth (p = 0.009), higher satisfaction during birth in relation to holding the baby (p > 0.000), and the meeting of expectations (p = 0.017). These associations disappear when the type of birth is introduced. Maintenance of breastfeeding is associated with maternal personality and psychosocial variables: openness to experience (p = 0.007), increased worries about coping with the baby (p = 0.046), relationship with partner (p = 0.047), and overt emotional expression (p = 0.040).

CONCLUSION: Different factors are associated with initiation and maintenance of breastfeeding. Specific prevention strategies are needed, aimed toward health care staff for improving breastfeeding initiation and to empower women during the entire pregnancy for breastfeeding maintenance.
