Timeframe: Change from baseline in Healthy Eating Index at the end of the school year (SY2).

Population: The number of participants does not match that the the flow chart, and we were not able to to get post (SY2) HEI measures in all of the enrolled students.

Change in the total Healthy Eating Index score from baseline to SY2. The Healthy Eating Index (HEI) score is a measure of diet quality. HEI scores can range from 0 to 100, with 0 representing the least overall healthy diet, and 100 representing the most overall healthy diet

OTHER_PRE_SPECIFIED outcome

Timeframe: Change in perceived support from baseline at the end of the school year (SY2)

Change in social support from baseline to SY2. Assessment of social support for breakfast was measured by asking the students to consider a typical month and record how often the following people encouraged them to eat or continue to eat breakfast at school: (1) parent/guardian, (2) friend, (3) other kids at my school, (4) teacher, and (5) other school staff. A 4-point Likert-type scale (disagree to agree, 0-4) for each of the categories was used. The total scale summed the five categories. The scale ranged from 0-20, a higher score indicates more social support.
