Effectiveness of a home-based peer support programme for Chinese mothers with low breastfeeding self-efficacy to increase the exclusivity and duration of breastfeeding: study protocol of a randomised control trial.

Abstract

Breastfeeding is associated with many health benefits for both women and their newborns. Exclusive breastfeeding has been recommended for at least 6 months to optimise infant growth, development and health. In addition to standard care, community-based peer support is recommended to help mothers improve breastfeeding. A recent survey reveals that the rate of exclusive breastfeeding at 6 months post partum in Hong Kong is low, and half of all breastfeeding mothers never exclusively breastfeed. Taking into account the local practice for women to stay home during the first month post partum and social isolation during and post-COVID-19 pandemic, a home-based peer support programme with the aid of Zoom or Facetime is proposed. This study aims to evaluate the effectiveness of a home-based breastfeeding peer support programme in improving breastfeeding practices and achieving exclusive breastfeeding rate among women with low breastfeeding self-efficacy. The study is a two-armed randomised control trial and will include a total of 442 participants. Potential cases will be recruited and screened at four postnatal wards in Hong Kong public hospital. Eligible and consented cases will be randomly allocated into intervention or control groups at a 1:1 ratio. Control group (n=221) will receive standard care, while the intervention group (n=221) will receive home-based peer support as well as standard care. Trained peer counsellors will provide breastfeeding-related support through Zoom or Facetime at 10 days and 1 month post partum. Telephone follow-ups will be conducted at 1 month, 2 months, 3 months and 6 months post partum. Breastfeeding status, mother's breastfeeding self-efficacy and postpartum depression will be assessed and compared between the two arms. The study has been reviewed and approved by the Institutional Review Board of the University of Hong Kong and Hospital Authority Hong Kong West Cluster (UW 20-564). The findings will be updated in trial registries and disseminated in peer-reviewed journals and academic conferences. NCT04621266.
