This paper aims to explore the assumptions concerning the dynamics of human action underpinning breastfeeding promotion campaigns in the UK. Drawing on qualitative interviews with mothers, the ways in which three problematic assumptions shape both the promotion and experience of contemporary breastfeeding promotion campaigns are explored, in the light of Joas’s theorisation of action’s creativity and pragmatism. Public health efforts to establish breastfeeding as a rational standard against which good mothering can be judged, in ways which rely on a de-contextualised understanding of human action as instrumentally rational, where bodies are imagined as pliable instruments of human intentions, are explored as they play out in the experiences of women embarking on motherhood. The paper concludes that a target-driven health-promotion policy, relying on a mechanistic account of social and emotional life, is contributing to the burden of early motherhood in ways that are not conducive to infant and maternal health and attachment.

Pregnancy and the postpartum period is a time of increased vulnerability for retention of excess body fat in women. Breastfeeding (BF) has been shown to have many health benefits for both mother and baby; however, its role in postpartum weight management is unclear. Our aim was to systematically review and critically appraise the literature published to date in relation to the impact of BF on postpartum weight change, weight retention and maternal body composition. Electronic literature searches were carried out using MEDLINE, EMBASE, PubMed, Web of Science, BIOSIS, CINAHL and British Nursing Index. The search covered publications up to 12 June 2012 and included observational studies (prospective and retrospective) carried out in BF mothers (either exclusively or as a subgroup), who were 2 years postpartum and with a body mass index (BMI) >18.5 kg m(-2), with an outcome measure of change in weight (including weight retention) and/or body composition. Thirty-seven prospective studies and eight retrospective studies were identified that met the selection criteria; studies were stratified according to study design and outcome measure. Overall, studies were heterogeneous, particularly in relation to sample size, measurement time points and in the classification of BF and postpartum weight change. The majority of studies reported little or no association between BF and weight change (n=27, 63%) or change in body composition (n=16, 89%), although this seemed to depend on the measurement time points and BF intensity. However, of the five studies that were considered to be of high methodological quality, four studies demonstrated a positive association between BF and weight change. This systematic review highlights the difficulties of examining the association between BF and weight management in observational research. Although the available evidence challenges the widely held belief that BF promotes weight loss, more robust studies are needed to reliably assess the impact of BF on postpartum weight management.International Journal of Obesity advance online publication, 20 August 2013; doi:10.1038/ijo.2013.132.

Background: The postpartum period is a vulnerable time for excess weight retention, particularly for the increasing number of women who are overweight at the start of their pregnancy and subsequently find it difficult to lose additional weight gained during pregnancy. Although postpartum weight management interventions play an important role in breaking this potentially vicious cycle of weight gain, the effectiveness of such interventions in breastfeeding women remains unclear. Our aim was to systematically review the literature about the effectiveness of weight management interventions in breastfeeding women.

Methods: Seven electronic databases were searched for eligible papers. Intervention studies included were carried out exclusively in breastfeeding mothers, ≤2 years postpartum and with a body mass index greater than 18.5 kg/m2, with an outcome measure of change in weight and/or body composition.

Results: Six studies met the selection criteria, and were stratified according to the type of intervention and outcome measures. Despite considerable heterogeneity among studies, the dietary-based intervention studies appeared to be the most efficacious in promoting weight loss; however, few studies were tailored toward the needs of breastfeeding women.

Conclusions: Weight management interventions which include an energy-restricted diet may play a key role in successful postpartum weight loss for breastfeeding mothers.

BACKGROUND: Ireland continues to rank among countries with the lowest breastfeeding initiation rates. National and regional studies also show that few women in Ireland who initiate exclusive breastfeeding continue to breastfeed for the recommended 6 months.

AIM: To assess the rate of exclusive and partial breastfeeding in Ireland at three time periods: birth to 48 h, 3-4 months following birth, and when the infant was 6-7 months old.

METHODS: A longitudinal national cohort survey of 2527 mothers.

RESULTS: Findings show that just 56 % (n = 1002) of mothers initiated breastfeeding at birth and, at 48 h, 42 % (n = 1064) of women were exclusively breastfeeding their babies. At 6-7 months, only 2.4 % of the 2527 mothers who took part, reported exclusive breastfeeding. Irish women were less likely to initiate breastfeeding (52.6 %) compared with Polish (82.2 %), British (64.5 %), and other nationalities (74.6 %). Multivariate analysis also revealed significant relationships between initiation and socio-economic variables, with mothers' health insurance status being of particular importance.

CONCLUSION: The results highlight the necessity to support the initiation and maintenance of breastfeeding in Ireland, in order to reduce rates of infant morbidity.

Breastfeeding rates in Northern Ireland are substantially lower in Northern Ireland compared to the rest of the United Kingdom (McAndrew et al, 2012). Midwives carry a responsibility within their health promotion activities to reiterate the benefits of breastfeeding and support women to make empowered decisions with regard to feeding their baby. This poster explores some of the challenges faced by midwives in relation to supporting women to make empowered choices and explores how midwives can help normalise breastfeeding within the clinical practice setting

The importance of father involvement in the young family is increasingly evident. This research was conducted using the theory of planned behaviour to understand important aspects contributing to father invo lvement in the breastfeeding process. Eighty mothers and 65 fathers of one-year-old children completed a questionnaire regarding father involvement (FI) in breastfeeding. Measures included attitudes, subjective norms, and perceived behaviour control regarding FI and the extent to which fathers demonstrated involvement by advocating for and affIrming breastfeeding, being present during breastfeeding, providing household help, and being responsive to their partners' needs. Results suggest that mothers and fathers experience FI differently. Mothers' perceptions are motivated by intrinsic attitudinal considerations, whereas fathers' involvement is primarily motivated by the opinions of others. Interventions should focus on increasing fathers' perception of societal approval through approaches such as peer-led groups, and increasing mothers' approval through information of the value of fathers' involvement in the breastfeeding process.
