Recent research among postpartum women has considered body image and eating attitudes as well as exclusive breastfeeding within common theoretical models. However, these efforts have so far neglected to include partner-related constructs, which constitutes an important gap. Thus, the aim of this study was to examine an integrated model of body image and eating concerns, and exclusive breastfeeding among mothers of infants six months and younger, that included partner appearance influences as well as general postpartum support.
