A longitudinal study of the effect of psychosocial factors on exclusive breastfeeding duration

Objective
to examine the effect of psychosocial factors on exclusive breastfeeding duration to six months postpartum

Design
longitudinal, prospective questionnaire based study.

Setting
participants were recruited from a publically funded antenatal clinic located in the western metropolitan region of Melbourne, Victoria, Australia and asked to complete questionnaires at three time points; 32 weeks pregnancy, two months postpartum and six months postpartum.

Participants
the participants were 125 pregnant women aged 22–44 years.

Measurements and findings
psychosocial variables such as breastfeeding self-efficacy, body attitude, psychological adjustment, attitude towards pregnancy, intention, confidence and motivation to exclusively breastfeed and importance of exclusive breastfeeding were assessed using a range of psychometrically validated tools. Exclusive breastfeeding behaviour up to six months postpartum was also measured. At 32 weeks gestation a woman׳s confidence to achieve exclusive breastfeeding was a direct predictor of exclusive breastfeeding duration to six months postpartum. At two months postpartum, psychological adjustment and breastfeeding self-efficacy were predictive of exclusive breastfeeding duration. Finally, at six months postpartum, psychological adjustment, breastfeeding self-efficacy, confidence to maintain and feeling fat were directly predictive of exclusive breastfeeding duration.
