结局指标
主要结局
FEV1
时间窗: 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
ACT
时间窗: 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.
Skin Carotenoid Level
时间窗: 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.
Diet Intake
时间窗: 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.
