 The food and physical activity environments of homes and child care centers will be assessed using the Home Self-administered Tool for Environmental assessment of Activity and Diet HomeSTEAD Hales 2014 and the Environment and Policy Assessment and Observation EPAO Ward 2008. HomeSTEAD is a self-administered survey that assesses characteristics of the home environment that influence childrens diet and physical activity behaviors. The EPAO is an observation protocol that will provide similar data about the food and physical activity environments at child care centers. EPAO observations will be completed during the center visit by trained and certified data collectors. Data from HomeSTEAD and EPAO will be used to calculate scores for home and center nutrition and physical activity environments.
