| Measure | Description | Time Frame |
|---|---|---|
| FEV1 | forced expiratory volume in one second | 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. |
| ACT | Asthma control test results in a score of 5-25, with a lower score indicating better asthma control. | 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 | 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. | 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. |
| Diet Intake | Nutrascreen diet questionnaire to assess nutritional intake. Specifically, quantity of fruits and vegetable intake will be assessed. | 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. |
