Multicomponent perinatal breastfeeding support in women with BMI >25: The Latch On multi-centre randomised trial.

OBJECTIVE: To investigate the effectiveness of a multicomponent breastfeeding support intervention on breastfeeding prevalence at 3 months among women with a body mass index (BMI) >25 kg/m2. DESIGN: Multicentre multicomponent randomised controlled trial. SETTING: Four maternity centres in Ireland. POPULATION: A total of 225 primiparous women and their nominated support partners. Participants were aged 18 years and over, with BMI ≥25 kg/m2, carrying a singleton pregnancy and without contraindication for breastfeeding. METHODS: The intervention included an antenatal group breastfeeding education session for participants and their support partners, followed by a planned postnatal breastfeeding assessment and telephone support for up to 6 weeks by a lactation consultant. MAIN OUTCOME MEASURES: Any breastfeeding at 3 months postpartum. RESULTS: Any breastfeeding prevalence was 68.7% (n = 68) in the intervention group and 62.1% (n = 59) in the control group at 3 months postpartum (odds ratio 1.33, 95% confidence interval 0.72-2.46, p = 0.36). Any and exclusive breastfeeding rates did not significantly differ at any other time point. More women in the control group accessed support from private lactation consultants (intervention 23.5% [n = 12], control 45.3% [n = 24], p = 0.02). CONCLUSIONS: The control group had higher than expected breastfeeding rates, and the study found no evidence of effect on the primary outcome. Providing comprehensive education and support for women intending to breastfeed remains of paramount importance.

Latch On: A protocol for a multi-centre, randomised controlled trial of perinatal support to improve breastfeeding outcomes in women with a raised BMI.

INTRODUCTION: Breastfeeding is associated with improved maternal and child outcomes. Women with a higher body mass index (BMI), who comprise about 50% of the population, are at increased risk of poorer breastfeeding practices and are a population who would benefit from breastfeeding. METHODS: This protocol is for a multi-centre, randomised controlled trial of perinatal breastfeeding support among primiparous women with a BMI >25 kg/m2, using a previously-tested, multi-component intervention. The primary outcome is any breastfeeding at 3 months. The intervention will support mothers and their partners and spans from late pregnancy to six weeks postpartum. Intervention components include group antenatal breastfeeding education, individual face-to-face education in the immediate postnatal period, professional support to six weeks' postpartum and weekly phone calls in the immediate postpartum period from an International Board Certified Lactation Consultant (IBCLC). The intervention will target attitudes towards breastfeeding, breastfeeding self-efficacy, and subjective norms around infant feeding with the aim to normalise the behaviour. RESULTS: We anticipate that the intervention will be well-accepted and feasible to carry out within four maternity units in the East of Ireland. Furthermore, essential formative qualitative work has been conducted to inform the intervention design and to ensure that it is contextually appropriate. CONCLUSION: The proposed intervention will be invaluable to policy-makers in providing insights into what specific interventions are effective in improving breastfeeding rates for women with a raised BMI.

Antenatal breastfeeding self-efficacy and breastfeeding outcomes among mothers participating in a feasibility breastfeeding-support intervention.

BACKGROUND: Breastfeeding rates in Ireland are among the lowest worldwide. A feasibility study of a breastfeeding-support intervention explored maternal characteristics associated with antenatal breastfeeding self-efficacy and with infant-feeding mode at 6 weeks postpartum among women giving birth in Ireland. METHODS: We conducted a prospective study across two sites, urban and rural: The National Maternity Hospital (NMH), Dublin and Wexford General Hospital (WGH), Wexford. Nulliparous, pregnant women were recruited at approximately 32 weeks gestation from the hospitals' antenatal out-patient departments. Participants attended an antenatal class with a support partner, received a one-to-one session with a lactation consultant after delivery and had access to a breastfeeding-support clinic and telephone advice postpartum. Our aim was to understand maternal variables associated with breastfeeding self-efficacy and infant-feeding mode. We explored associations between continuous and categorical variables and any breastfeeding and exclusive breastfeeding using t tests and Chi-squared analyses. RESULTS: One hundred mothers provided baseline data; 64 provided follow-up data. Lower maternal age and non-Irish nationality were associated with higher antenatal breastfeeding self-efficacy. At the rural unit, mothers with tertiary education were more likely to be exclusively breastfeeding than those with secondary education. Though not statistically significant, more normal-weight mothers from the urban unit were exclusively breastfeeding at 6 weeks than overweight/obese mothers. CONCLUSIONS: Breastfeeding outcomes differed by maternal education. Future interventions should target mothers with lower education and possibly also overweight and obese mothers. Increasing breastfeeding self-efficacy, particularly among older and Irish-born mothers, may be a mechanism for improving breastfeeding outcomes.

A feasibility study of a multidimensional breastfeeding-support intervention in Ireland.

BACKGROUND: Breastfeeding is the optimum mode of infant feeding. Despite this, most global populations do not achieve the World Health Organisation's recommendation of exclusive breast milk for the first 6 months of life. Irish breastfeeding rates are among the lowest in Europe, necessitating a well-designed breastfeeding-support intervention. AIM: To evaluate the feasibility and acceptability of a multidimensional breastfeeding intervention in a rural and an urban maternity setting in Ireland. DESIGN: A feasibility study of a breastfeeding-support intervention. SETTING: Participants were recruited from The National Maternity Hospital (Dublin, urban) and Wexford General Hospital (Wexford, rural). Questionnaires were completed antenatally, at 6 weeks postpartum and at 3 months postpartum to assess acceptability of the intervention and determine breastfeeding status. PARTICIPANTS: Pregnant women were recruited in the 3rd trimester, alongside a support partner. INTERVENTION: The intervention consisted of an antenatal class (including the physiology and practical approaches to breastfeeding), a one-to-one breastfeeding consultation with a lactation consultant after birth, access to a breastfeeding helpline, online resources, and a postnatal breastfeeding support group which included a one-to-one consultation with the lactation consultant. RESULTS: One hundred women from The National Maternity Hospital, Dublin and 27 women from Wexford General Hospital were recruited. The antenatal class was attended by 77 women in Dublin and 23 in Wexford; thus, 100 women participated in the intervention. Seventy-six women had a one-to-one postnatal consultation with a lactation consultant in Dublin and 23 in Wexford. Fifty and 45 women in Dublin, and 15 and 15 in Wexford responded to the 6-week and 3-month questionnaires, respectively. At 3 months postpartum, 70% of respondents from Dublin and 60% from Wexford were breastfeeding. Mothers perceived the one-to-one consultation with the lactation consultant during postnatal hospitalization as the most helpful part of the intervention. Inclusion of a support partner was universally viewed positively as a means to support the mother's decision to initiate and continue breastfeeding. CONCLUSION: This multidimensional intervention is well-accepted and feasible to carry out within an Irish cohort, in both urban and rural areas. Data from this feasibility study will be used to design a randomized controlled trial of a breastfeeding-support intervention.
