The effectiveness and cost-effectiveness of Assets-based feeding help Before and After birth (ABA-feed) for improving breastfeeding initiation and continuation: protocol for a multicentre randomised controlled trial (Version 3.0)

Abstract

Introduction
Breastfeeding has health benefits for infants and mothers, yet the UK has low rates with marked social inequalities. The Assets-based feeding help Before and After birth (ABA) feasibility study demonstrated the acceptability of a proactive, assets-based, woman-centred peer support intervention, inclusive of all feeding types, to mothers, peer supporters and maternity services. The ABA-feed study aims to assess the clinical and cost-effectiveness of the ABA-feed intervention compared to usual care in first-time mothers in a full trial.
Methods and analysis
A multicentre randomised controlled trial with economic evaluation to explore clinical and cost-effectiveness, and embedded process evaluation to explore differences in implementation between sites.
We aim to recruit 2730 primiparous women, regardless of feeding intention. Women will be recruited at 10-15 sites from antenatal clinics and various remote methods including social media and invitations from midwives and health visitors. Women will be randomised at a ratio of 1.43:1 to receive either ABA-feed intervention or usual care. A train the trainer model will be used to train local Infant Feeding Coordinators to train existing peer supporters to become ‘Infant Feeding Helpers’ in the ABA-feed intervention.
Infant feeding outcomes will be collected at 3 days, and 8, 16 and 24 weeks post-birth. The primary outcome will be any breastfeeding at 8 weeks post-birth. Secondary outcomes will include breastfeeding initiation, any and exclusive breastfeeding, formula feeding practices, anxiety, social support and health care utilisation. All analyses will be based on the intention-to-treat principle.
Ethics and dissemination
The study protocol has been approved by the East of Scotland Research Ethics Committee. Trial results will be available through open-access publication in a peer-reviewed journal and presented at relevant meetings and conferences.
