174 Development of an Individualized Responsive Feeding Coaching Intervention

Abstract

OBJECTIVES/GOALS: Responsive infant feeding (RIF) promotes healthy dietary patterns and infant weight gain. Research is needed to assist caregivers recognize infant hunger/satiety cues and overcome barriers to using RIF. The Learning Early Infant Feeding Cues (LEIFc) intervention was designed to fill this gap by using a validated coaching approach to promote RIF. METHODS/STUDY POPULATION: Guided by the Obesity-Related Behavioral Intervention Trials (ORBIT) model, this proof-of-concept study tests the feasibility and fidelity of the LEIFc intervention in mother-infant dyads (N=25). Study visits from the 3rd trimester of pregnancy to 4 months postpartum (PP) are conducted in family homes. Use of RIF via subjective (survey) and objective (video) measures is collected at 1 and 4 months PP. Prenatally written and video material on infant feeding and infant hunger/satiety cues is provided. At 2 and 3 months PP, coaching during a feeding session is provided by a trained interventionist using the SS-OO-PP-RR (super, Setting the Stage, Observation & Opportunities, Problem Solving & Planning, Reflection & Review) approach. Qualitative data on LEIFc are provided by the interventionist and participants. RESULTS/ANTICIPATED RESULTS: To date 25 dyads have been enrolled and 4 have completed all study visits. Preliminary analyses showed that subjective measure of awareness of infant cues increased post intervention (pre, M=4.38 vs post, M=4.63). LEIFc has been well accepted by participants including use of the SS-OO-PP-RR approach. Data suggests refinement to LEIFc is needed to include breastfeeding and mental health support as well as a longer duration of intervention through at least 6 months PP. An experienced interventionist is key to success of the research. All lost to follow-up (n=7) have occurred before the first PP visit suggesting that at study visit closer to birth is needed. Enrollment will continue through December 2022 and data collection through April 2023. DISCUSSION/SIGNIFICANCE: After refinement, the LEIFc intervention will be tested in a pilot RCT. The long-term goal is to implement LEIFc in the curricula of federally funded maternal-child home visiting programs who serve vulnerable populations; those that often have infant feeding practices that do not align with recommendations and are less likely to use RIF.
