Overview

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.

After consenting to join the study, all participants enter a single cohort, cross-sectional study to assess pulmonary function, asthma control, carotenoid level, and diet intake.

Outcomes

Primary Outcomes

FEV1

forced expiratory volume in one second

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.

ACT

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

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

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.

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.

Diet Intake

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

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.
