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

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

longitudinal, prospective questionnaire based study.

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.

the participants were 125 pregnant women aged 22-44 years.

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.

psychosocial factors are significantly predictive of exclusive breastfeeding duration. Self-efficacy, psychological adjustment, body image, motivation and confidence are all important psychosocial factors implicated in a woman's ability to maintain exclusive breastfeeding over time.

Individualised antenatal breastfeeding education and support may be strengthened by strategies that build a woman's confidence to exclusive breastfeeding. Implementing psychosocial supports and methods providing positive feedback that increase a woman's self-efficacy to exclusively breastfeed to six months are also important two months postpartum.
