A district wants to measure the impact of a new adolescent nutrition intervention targeting peer influence and family meals. Which set of outcome metrics would best capture nutrition-related changes over one school year?

Frequency of family meals per week, percent of students reporting fast-food consumption twice or more per week, change in average fruit and vegetable servings per day, and BMI percentile changes and self-reported disordered eating screening scores.

Only academic test scores and teacher-reported classroom behavior, since nutrition programs primarily affect cognition without measurable dietary or anthropometric outcomes.

Number of vending machines in the district and annual cafeteria revenue, but not any student-reported dietary intake or BMI measures, because revenue is the primary proxy for diet quality.

Monthly counts of missed school buses and average sleep duration, as these are direct indicators of adolescent dietary intake changes following interventions.
