Abstract
Breastfeeding is important for infant and maternal physical and mental health. Despite this, the United Kingdom (UK) and Ireland have the lowest breastfeeding rates in the world with between 34% and 52% of women breastfeeding partially or exclusively at 6-8 weeks across the nations. This is driven by complex biological, social, psychological and economic factors. However, a significant body of evidence shows that mothers who receive skilled breastfeeding support are more likely to breastfeed for longer. Effective breastfeeding support can be delivered by a range of trained professionals and peer supporters depending on need. The highest specialist support is provided by International Board Certified Lactation Consultants (IBCLCs). Research from the USA has shown the positive impact of IBCLC support upon breastfeeding duration and experience. However, there is limited data on this topic from the UK and Ireland. Given significant differences in IBCLC access and health care systems, this review therefore aimed to explore the impact of IBCLCs in the UK and Ireland. Of 5169 papers retrieved, only four studies met the eligibility criteria. Four themes were identified; breast milk feeding rates increased, breastfeeding duration increased, lack of specialised IBCLC support available outside of study and format of support delivery, including group based or 1-1 support. The findings show increased access to IBCLC support may increase breastfeeding rates in the UK and Ireland. However, the findings are limited due to poor quality studies and recruitment bias. The paucity of evidence highlights the need for further research on this topic.
