Outcome Measures

Primary Outcomes (2)

  • fruits and vegetables (FV) selection

    Amount of FV selection will be calculated based on digital photographs of student's lunch trays before consumption

    Baseline to up to 6 weeks after salad bars installed

  • FV consumption

    Amount of FV consumed will be calculated by subtracting amount of FV remaining after lunch is consumed from amount of FV selected based on digital photographs of student's lunch trays before and after consumption.

    Baseline to up to 6 weeks after salad bars installed

Secondary Outcomes (6)

  • energy intake (kcal)

    Baseline to up to 6 weeks after salad bars installed

  • dietary quality (Healthy Eating Index)

    Baseline to up to 6 weeks after salad bars installed

  • fruits and vegetables (FV) selection post-COVID-19

    4-6 weeks after salad bars re-installed

  • FV consumption post-COVID-19

    4-6 weeks after salad bars re-installed

  • energy intake (kcal) post-COVID-19

    4-6 weeks after salad bars re-installed

  • +1 more secondary outcomes
