A study published in Breastfeeding Medicine determined the factors associated with timely initiation of breastfeeding at immediate postpartum and the variables that assist with their maintenance 4 months after birth. Researchers used a longitudinal prospective design, 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). In all, 116 women were included in the study from the first trimester to 4 months after birth. Timely initiation of breastfeeding is linked with vaginal birth and with variables related to the absence of stress factors - lesser worries regarding childbirth, higher satisfaction during birth in relation to holding the baby, and meeting of expectations. These associations seem to disappear when the type of birth is introduced. Maintenance of breastfeeding appears to be associated with maternal personality and psychosocial variables: openness to experience, increased worries about coping with the baby, relationship with partner, and overt emotional expression. It was concluded that several factors are associated with initiation and maintenance of breastfeeding. Therefore, specific prevention strategies, aimed toward health care staff for improving breastfeeding initiation and empowering women during the pregnancy for breastfeeding maintenance are required.
