Experimental: Food-Body-Mind intervention

Guided by the Actor-Partner Interdependence Model, the Allostatic Load Model, and the Transactional Theory of Stress and Coping, the proposed 16-week Food-Body-Mind intervention includes: 1) a school-based mindfulness component delivered to equip preschoolers with knowledge and skills in mindful eating and movement (e.g., yoga, deep breathing exercises); 2) a home-based mindfulness component to increase caregivers' skills in practicing mindful eating, movement, and parenting behaviors at home to foster a more positive, mindful, and healthy home environment; and 3) a school learning and home practice connection component to improve caregiver-preschooler relationships.

No_intervention: Usual care control

Like those in the intervention group, preschoolers assigned to the control group will receive usual Head Start activities during the intervention period. After the 12-month follow-up data collection from both intervention and control participants in each year, each control family will receive all intervention supplies including the Tasty Healthy Cookbook, MyPlate plates, and a breathing ball, as well as the program manual on how to use the intervention supplies. These intervention supplies will be distributed to control families at the end of in-person data collection appointments. Moreover, a virtual caregiver meeting on mindful eating, movement, and parenting will be provided to all caregivers who are interested.
