NCT04258709

Brief Summary

The purpose of this randomized controlled trial is to examine the impact of a remotely-delivered antenatal milk expression (AME) intervention versus an attention control condition on breastfeeding outcomes among a sample of 280 nulliparous, non-diabetic women with pre-pregnancy body mass indices ≥ 25. AME involves milk expression and collection in the third pregnancy trimester and is theorized to address multiple barriers to breastfeeding among women with higher BMI, including impaired breastfeeding self-efficacy, insufficient milk supply (critical period endocrine modulation of milk volume), and early formula supplementation in the context of a medically complex birth (availability of banked antenatal milk). Participants will be enrolled in their third trimester of pregnancy and allocated into one of two study arms: 1) AME instruction delivered by remote, live International Board Certified Lactation Consultants via an innovative app-based telelactation platform; or 2) an attention control condition (video-based infant care education unrelated to infant feeding). Video-based education for both groups will occur in weekly study visits from 37 to 40 weeks gestation, with women in the intervention group continuing AME 1-2 times per day at home. Measured outcomes of interest will include short and long-term breastfeeding practices (e.g., breastfeeding duration, exclusivity) and participants' experiences with and perceptions of AME.

Study Arms (2)

Antenatal Milk Expression (AME) Intervention Group

EXPERIMENTAL

Weekly video interactions (weeks 37-40 of pregnancy) with International Board Certified Lactation Consultants (IBCLCs) to teach and reinforce antenatal milk expression. At-home practice of hand expression and collection of any expressed milk.

Behavioral: AME

Video-based Infant Care Education Control Group

ACTIVE COMPARATOR

Weekly video education (weeks 37-40 of pregnancy) on various topics related to infant care (e.g., safe sleep, car seat safety, etc.).

Behavioral: Video-based infant care education

Interventions

AMEBEHAVIORAL

Participants receive education on AME and feedback on technique with a remotely-based IBCLC via live streaming video.

Antenatal Milk Expression (AME) Intervention Group

Participants view a standard set of web-based streamed videos addressing evidence-based infant care, unrelated to feeding/breastfeeding.
