Treatment and study plan

Primary outcomes

  1. FEV1

    Time frame: measured at a single time point when recruited in the study (cross sectional). Study outcomes will be reported upon study completion, approximately 1 year from study onset.

    forced expiratory volume in one second

  2. ACT

    Time frame: measured at a single time point when recruited in the study (cross sectional). Study outcomes will be reported upon study completion, approximately 1 year from study onset.

    Asthma control test results in a score of 5-25, with a lower score indicating better asthma control.

  3. Skin Carotenoid Level

    Time frame: measured at a single time point when recruited in the study (cross sectional). Study outcomes will be reported upon study completion, approximately 1 year from study onset.

    Skin carotenoid level, measured with a non-invasive tool and is an indicator of fruit and vegetable intake. Skin carotenoid levels are shown as a score of 0-800, with a higher score representing a higher level of carotenoids.

  4. Diet Intake

    Time frame: measured at a single time point when recruited in the study (cross sectional). Study outcomes will be reported upon study completion, approximately 1 year from study onset.

    Nutrascreen diet questionnaire to assess nutritional intake. Specifically, quantity of fruits and vegetable intake will be assessed.
