Families enrolled in Chicago Park District programs will be offered the opportunity to participate in the BUILT family lifestyle program. Using a single group design, measures will be taken within two weeks of program start and two weeks after completion. Additional feasibility measures will be taken during the program itself to inform refinements across iterations. The BUILT program will occur largely on-line and consist of weekly home challenges related to food, sleep, and exercise that add up to form a comprehensive home routine--the routine will optimize neurocognitive development and home structure. The program will be co-facilitated by UIC students and Chicago Park District staff. For more information visit the program website: https://built.ahs.uic.edu.
