Disordered eating from pregnancy to the postpartum period: The role of psychosocial and mental health factors.

The postpartum period has been identified as high-risk period for the increase of disordered eating. This study examined the psychosocial factors-attitudes to motherhood, self-compassion and relationship satisfaction- and mental health factors-depressive and anxiety symptoms-associated with this increase. One hundred and fourteen women completed online questionnaires about their eating behaviours between: 18-24 weeks gestation (T1), 30-32 weeks gestation (T2) and 8-10 weeks postpartum (T3). A cluster analysis examined the change of disordered eating from T2 to T3. Multinomial logistic regressions examined which demographic, psychosocial and mental health factors were associated with disordered eating cluster groups, as individual factors and as a combined model of predictors at T1, T2 and T3. Four cluster groups were identified: 'lower disordered eating', 'increasing risk', 'sub-clinical' and 'clinical'. All psychosocial and mental health predictors were individually associated with a risk group, when compared to the lower disordered eating group. However, when combined, only multiparity and higher depressive symptoms were associated with the sub-clinical group. Multiparity, higher pre-pregnancy body mass index and lower self-compassion were associated with the increasing risk group. This study introduces self-compassion as a psychosocial factor worthy of further investigation and application in the field of perinatal disordered eating, with promising avenues for antenatal intervention.
