Podium presentations starting now... #ABM2022 First up: #breastfeeding disparities and #SUID

Study included 4 years of births in US and linked SUID deaths #ABM2022
liebertpub.com/doi/10.1089/bf…

Mediation analysis estimated the extent to which breastfeeding disparities explained differences in SUID rates #ABM2022

Mediation analysis quantified the extent to which not #breastfeeding contributes to disparities - accounts for ~2% of increased rate of SUID for NH Black infants #ABM2022

Discussion: competing risks are likely more important to SUID risk than not breastfeeding, at least in NHB infants #ABM2022

Next presentation: Passing on Protection: Frequency of Breastfeeding and Protection Against COVID‐19 in Young Children of Vaccinated Mothers. #ABM2022 liebertpub.com/doi/10.1089/bf…

Context for research: pregnant and lactating women were excluded from clinical trials of mRNA COVID-19 vaccines... and no CDC registry was created for lactating people 🤦‍♀️ #ABM2022

Study aim: estimate a minimum number of feeds needed for some passive immunity, and whether maternal boosters provided increased protection to breastfed children #ABM2022

Non-blinded observational prospective cohort study of women physicians and their breastfed children assessing maternal COVID-19 mRNA vaccination effects; one-year self-reported outcome surveys were used for this analysis. #ABM2022

Take-away: weaning to ≤2 feeds per day was associated with increased risk of child COVID diagnosis #ABM2022

More than 2 feeds per day and receiving a boosters were both associated with reduced risk of COVID diagnosis in breastfed children #ABM2022

TBD: does being breastfed by a vacinated person confer additional protection for chidren who've been vaccinated? #ABM2022

Last plenary of the day: Peer to Peer Milk Sharing among physician co-worders in an Academic Institution #ABM2022 by Abigail Liberty #GoHeels @UNCObGynRes

While FDA opposes milk sharing, @BFMedicine focuses on shared decision-making #ABM2022

Physician are a high risk group for #breastfeeding - less likely to reach their feeding goals than the general population #ABM2022

To what extent do physicians practice informal milk sharing, and how does their experience influence how they counsel their patients? #ABM2022

From 2014 to present, 19 dyads reported sharing milk - love the network analysis! #ABM2022

Most sharing events were milk from an older infant being shared with a younger infant #ABM2022

Love this work! Kudos @abbyliberty1 ! #ABM2022

@abbyliberty1 Department culture: small amounts of informal donor milk shared "just in case" a supplement is needed in the early postparutm period. #ABM2022
