The aim of this study was to use constructs common to dominant health behaviour theories to determine if predisposing, reinforcing and enabling factors for healthy eating, physical activity and weight gain differed between healthy and overweight pregnant women. Methods Pregnant women (n = 664) aged 29 ± 5 (mean ± SD) years were recruited at 16 ± 2 weeks gestation. Measures were self-reported pre-pregnancy weight, psychosocial constructs for healthy eating, physical activity and GWG and demographic data. Height was measured at 16 weeks. Psychosocial constructs were compared between women with pre-pregnancy weight status of healthy (BMI < 25 kg/m.sup.2) and overweight (BMI [greater than or equal to] 25 kg/m.sup.2). Results Health behaviour intentions, positive outcome expectations and social support for healthy eating and physical activity were not different between healthy (66 %) and overweight (34 %) women. Overweight women had lower self-efficacy for healthy eating, physical activity and GWG (p < 0.001), higher negative outcome expectations for GWG (p = 0.004), and higher barriers to healthy eating (p = 0.002), and physical activity (p = 0.006). Conclusions for practice Both healthy and overweight women appear motivated to follow a healthy diet, exercise and avoid excess gestational weight during pregnancy. However many psychosocial factors associated with achieving these goals were different between healthy and overweight women. Health behaviour interventions tailored to overweight pregnant women should consider improving self-efficacy, providing support to overcome perceived barriers, validate positive changes made, and assist in managing negative expectations.

Early parenting is critical to effective attachment and a range of positive developmental outcomes for children. Feeding is a key task of early parenting and increasing evidence indicates that early feeding practices are important for the development of self-regulation of intake and food preferences which in turn are predictors of later obesity risk. However, relatively little is known about the mother-infant interaction at the transition to solids among typically developing children. This study aimed to describe parenting strategies used by mothers at the transition from milk feeding to solid food. Twenty mother-infant dyads were video-taped during a feeding interaction and data were analysed to describe maternal use of parenting strategies. It was predicted that positive feeding strategies would be correlated with lower levels of infant food refusal (IFR), higher maternal sensitivity, and better overall parenting scores. The opposite was predicted for negative feeding strategies. It was found that positive strategy use and general parenting scores were significantly correlated in the predicted direction, however maternal instruction, aversive contact, and ineffective strategy use were significantly correlated with and predictive of IFR. Additionally, it was hypothesised that maternal strategy use would deteriorate towards the end of the interaction, and this hypothesis was partially supported: significantly more negative strategy use was observed in the last third of the interaction, whilst positive strategy use remained consistent through the feeding interaction. The findings have important implications for early feeding parent education and intervention programmes.

There is increasing evidence that parenting and feeding interact to influence children's eating behaviour and weight status. Interpretation of existing research is complicated by the lack of consensus in the conceptualisation and measurement of both "parenting" and "feeding", particularly the distinction between "styles", "dimensions" and "practices". In addition, the lack of validated tools to concurrently assess feeding practices in infancy limits the capacity to examine the relationships between parenting and feeding in infancy and their short- and long-term influence on weight status. In this paper, we provide an overview of the constructs examined in this emerging area of research, highlight the conceptual, definitional and measurement challenges and propose a unifying model to aid design and the interpretation of intervention studies. Progress on these methodological issues will contribute to the robust evidence required to justify investment in interventions that focus on parenting and feeding in the context of child obesity prevention.
