The influence of psychological factors on post-partum weight retention at 9 months

ObjectivesPost-partum weight retention (PWR) has been identified as a critical pathway for long-term overweight and obesity. In recent years, psychological factors have been demonstrated to play a key role in contributing to and maintaining PWR. DesignTherefore, the aim of this study was to explore the relationship between post-partum psychological distress and PWR at 9months, after controlling for maternal weight factors, sleep quality, sociocontextual influences, and maternal behaviours. MethodPregnant women (N=126) completed a series of questionnaires at multiple time points from early pregnancy until 9months post-partum. ResultsHierarchical regression indicated that gestational weight gain, shorter duration (6months or less) of breastfeeding, and post-partum body dissatisfaction at 3 and 6months are associated with higher PWR at 9months; stress, depression, and anxiety had minimal influence. ConclusionInterventions aimed at preventing excessive PWR should specifically target the prevention of body dissatisfaction and excessive weight gain during pregnancy.
