Relationships between maternal overweight prior to pregnancy, feeding mode and infant feeding beliefs and practices

This study aimed to examine whether pre-pregnancy weight status was associated with maternal feeding beliefs and practices in the early post-partum period.

This study uses secondary analysis of longitudinal data from Australian mothers. Participants (n = 486) were divided into two weight status groups based on self-reported pre-pregnancy weight and measured height: healthy weight (body mass index (BMI) <25 kg/m(2) ; n = 321) and overweight (BMI > 25 kg/m(2) ; n = 165). Feeding beliefs and practices were self-reported via an established questionnaire that assessed concerns about infant overeating and undereating, awareness of infant cues, feeding to a schedule and using food to calm.

Infants of overweight mothers were more likely to have been given solid foods in the previous 24 h (29% vs. 20%) and fewer were fully breastfed (50% vs. 64%). Multivariable regression analyses (adjusted for maternal education, parity, average infant weekly weight gain, feeding mode and introduction of solids) revealed that pre-pregnancy weight status was not associated with using food to calm, concern about undereating, awareness of infant cues or feeding to a schedule. However, feeding mode was associated with feeding beliefs and practices.

Although no evidence for a relationship between maternal weight status and early maternal feeding beliefs and practices was observed, differences in feeding mode and early introduction of solids were observed. The emergence of a relationship between feeding practices and maternal weight status may occur when the children are older, solid feeding is established and they become more independent in feeding.
