Key Takeaway
Note that ABA-feed peer support did not improve breastfeeding rates versus usual care in UK nulliparous women.

A randomised controlled trial was conducted across 17 localities in the UK offering breastfeeding peer support as part of usual care between January 2022 and April 2024. The study population consisted of 2475 nulliparous women recruited between 20 and 35 weeks of gestation. Participants were randomised to receive either the ABA-feed (Assets based feeding help Before and After birth-feed) peer support intervention or usual breastfeeding support alone. The primary outcome was any breastfeeding at eight weeks after birth, with secondary outcomes including breastfeeding initiation, exclusive breastfeeding, formula feeding practices, anxiety, social support, and healthcare utilisation.

The primary analysis revealed no difference in any breastfeeding at eight weeks between the groups. The adjusted risk difference was 0.01, with a 95% confidence interval ranging from -0.03 to 0.04. Specifically, 1013 of 1452 women (69.8%) in the intervention group breastfed at eight weeks, compared to 698 of 1015 women (68.8%) in the usual care group. High rates of breastfeeding initiation were observed in both groups, at 94.2% for the intervention and 92.5% for usual care, though statistical significance was not reported for this comparison.

Regarding secondary outcomes, the intervention group reported higher social support at eight weeks, but this difference was not sustained at 16 weeks. No differences were observed for other secondary outcomes such as exclusive breastfeeding, formula feeding practices, anxiety, or healthcare utilisation. Safety data, including adverse events, serious adverse events, discontinuations, and tolerability, were not reported in the study. The trial was unblinded, which represents a key limitation. Funding sources and potential conflicts of interest were not reported.

In the context of UK practice where breastfeeding peer support is part of usual care, this proactive, assets-based intervention did not improve breastfeeding rates compared with standard support. Clinicians should interpret these results as indicating that this specific intervention model may not offer additional benefit over existing usual care for this population.

OBJECTIVE: To assess the effect of a proactive, assets based, peer support infant feeding intervention in addition to usual care on breastfeeding rates, formula feeding practices, and other outcomes, compared with usual breastfeeding support alone. DESIGN: UK based, multicentre, parallel group, unblinded, randomised controlled trial. SETTING: 17 localities in the UK that offered breastfeeding peer support as part of usual care between January 2022 and 30 April 2024. PARTICIPANTS: 2475 nulliparous women between 20 and 35 weeks of gestation were randomised 1.43:1, to account for potential clustering by peer supporter: 1458 to the ABA-feed (Assets based feeding help Before and After birth-feed) peer support intervention and 1017 to usual care. INTERVENTIONS: The ABA-feed intervention comprised person centred proactive peer support for infant feeding underpinned by an assets based approach (focusing on the capabilities of, and resources available to, participants) and behaviour change theory delivered in person and remotely by text and telephone call. Usual care included universal care from midwives and health visitors and could also include services that provided reactive support such as peer supporters in breastfeeding groups, counselling, helplines, and social media support groups. MAIN OUTCOME MEASURES: The primary outcome was any breastfeeding at eight weeks after birth. Secondary outcomes at eight, 16, and 24 weeks after birth included breastfeeding initiation, any and exclusive breastfeeding, formula feeding practices, anxiety, social support, and healthcare utilisation. Analyses were based on the intention-to-treat principle. RESULTS: Rates of any breastfeeding at eight weeks did not differ between the intervention group (1013/1452; 69.8%) and usual care group (698/1015; 68.8%); adjusted risk difference 0.01, 95% confidence interval -0.03 to 0.04. Preplanned subgroup analyses showed no interactions between the intervention and age, prespecified feeding intentions, mother's education, index of multiple deprivation fifth, or relationship status. Breastfeeding initiation rates were high (intervention 94.2%; usual care 92.5%). At eight weeks the intervention group reported higher social support, but this was not sustained at 16 weeks. No differences were observed in other secondary outcomes. CONCLUSION: The ABA-feed peer support intervention did not improve breastfeeding rates compared with usual breastfeeding support in a UK context. TRIAL REGISTRATION: ISRCTN Registry ISRCTN17395671.
