(P42-31-26) Design of Micro Lessons for Remote Healthy Pregnancy Support in Arkansas: A Behavioral Intervention Support Tool for the GEM Study as a Protocol Design Element

Objectives: To translate the Dietary Guidelines for Americans and healthy pregnancy lifestyle recommendations into accessible, low-burden micro-lessons for delivery in de-centralized settings.

Methods: Micro-lesson development was guided by formative focus group findings identifying gaps in nutrition literacy and behavioral self-efficacy. Lessons were designed using 7taps™ (7taps OpCo LLC, West Palm Beach, FL, USA), a mobile-first microlearning platform designed for short, interactive educational content. Iterative revisions were made based on peer and faculty feedback to meet predefined educational and usability standards. Twenty interactive micro-lessons were developed and organized into six thematic clusters: (1) Glucose and metabolic health (2) Physical activity, (3) Healthy Eating in Pregnancy, (4) hydration, sleep, and stress management, (5) Individualized goal-setting and self-monitoring, and (6) Food safety. Lessons were designed to be concise, culturally relevant and behaviorally focused.

Results: The micro-lesson intervention is expected to improve nutrition literacy, self-efficacy, and confidence among pregnant women living in decentralized settings in and beyond Arkansas.

Conclusions: This partner-informed micro-lesson tool provides a scalable, low-burden approach to addressing knowledge gaps and supports future testing of its impact on behavior change and GWG outcomes.
