SECONDARY outcome

Timeframe: 2 month and approximately 9 month (end of school year) follow-up assessments

To test the effectiveness of the environmental tobacco smoke (ETS) reduction portion of the study, we will compare baseline cotinine values to 2 month (for smoke exposed participants) and final follow-up assessments (for all participants).

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: approximately 9 months (length of school year)

Cost-effectiveness will examine the net program costs to the number of symptom-free days gained. Benefits will be described as the net difference in medical and productivity costs between children in the treatment and control groups.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 1-9 months (Monthly Follow-up assessments)

We will look at additional asthma morbidity outcomes including symptom nights, days needing rescue medications, functional severity, days absent from school, and quality of life.
