Study name	Design and methodology of a cluster‐randomized trial in early care and education centers to meet physical activity guidelines: Sustainability via Active Garden Education (SAGE)
Methods	Aim: the primary objective of the SAGE C‐RCT is to determine the impact, transfer, and delivery of a garden‐based early care and education centres' physical activity and fruit and vegetables promotion intervention to improve health habits in Hispanic or Latino children aged 3–5 years. Secondary objectives are to investigate the process of delivery by measuring the reach, adoption, and implementation of the intervention. Design: cross‐over, C‐RCT, implemented in 28 early care and education centre sites in 3 cohorts over 3 years
Participants	Hispanic or Latino children aged 3–5 years attending participating 20 early care and education centres
Interventions	A garden‐based early care and education centre physical activity and fruit and vegetables promotion intervention for young children aged 3–5 years in 20 sites. The SAGE curriculum uses the plant lifecycle as a metaphor for human development. Children learn how to plant, water, weed, harvest, and do simple food preparation involving washing, cleaning, and sampling fruit and vegetables along with active learning songs, games, science experiments, mindful eating exercises, and interactive discussions to reinforce various healthy lifestyle topics. Parents will receive newsletters and text messages linked to the curriculum, describing local resources and events, and to remind them about activities and assessments.
Outcomes	Primary outcomes 1. Change physical activity; sedentary time (time frame: 4 assessment periods: baseline, 4 months, 8 months weeks, and 12 months) assessed by ActiGraph accelerometers 2. Fruit and vegetable consumption (time frame: 4 assessment periods: baseline, 4 months, 8 months weeks, and 12 months) 24 h diet recalls
