Brief Summary

The purpose of this study is to assess the use of a practical tool to objectively measure the fruit and vegetable intake in people with asthma.

Conditions

Asthma

Outcome Measures

Primary Outcomes (4)

• 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.
