Brief Summary:
The investigators propose a pilot, randomized trial of kitchen ventilation in the homes of children with asthma using a youth engaged research strategy.

Condition or disease Intervention/treatment Phase
Asthma in Children Pollution; Exposure Behavioral: Cooking Ventilation Intervention Not Applicable

Detailed Description:
In this trial of 60 children ages 6-12 with asthma, the investigators will randomize 30 children and their households to receive an intensive home kitchen ventilation intervention after one week of baseline data collection and the other 30 to receive the intervention after two weeks of baseline data collection. This design will allow for analysis as both a randomized controlled trial, and as a before/after trial, allowing for the benefits of both designs. The intervention includes education regarding improving ventilation in their homes during cooking and replacement of their range hood if it has inadequate flow or an intolerable noise level. During baseline data collection periods the households will be encouraged to continue their regular cooking patterns. The investigators will measure home particulate matter <2.5 microns (PM2.5) and nitrogen dioxide (NO2) levels for one week at baseline, one week after 30 families have received the intervention and a final week after all remaining families receive the cooking ventilation intervention, to assess for changes within each household as well as between groups. The investigators will also examine changes in airways inflammation (as measured by the exhaled fraction of nitric oxide, FeNO), lung function (as measured by spirometry), reported symptoms, and asthma quality of life after the baseline and each intervention period. Members of the research team have successfully conducted youth participatory action research in the low-income, high asthma prevalence community of Richmond, California (CA) as well as extensive youth participatory action research on other environmental health concerns in the low income city of Salinas, CA; using a similar model, the investigators aim to teach research methods to a new group of Richmond youth.

Arm Intervention/treatment
Intervention after One Week
This arm will have baseline data on air pollutant levels, stove use and range hood use collected for one week prior to receiving an educational intervention aimed at increasing use of the range hood. Data following the intervention will be collected for an additional two weeks.
Behavioral: Cooking Ventilation Intervention
An educational video presentation for the families regarding the importance of ventilation use during and after cooking, and strategies for improving the ventilation during cooking, has been created by Dr. Holm, with input from Youth Research Assistants (YRAs) The youth involvement will help to ensure that the information is presented in a way that will resonate with the local community and will also provide the youth with exposure to developing health education tools. The educational video will be shown to families at the time of the intervention visit and they will receive printed reminder materials of what they have learned.

Intervention after Two Weeks
This arm will have baseline data on air pollutant levels, stove use and range hood use collected for two weeks prior to receiving an educational intervention aimed at increasing use of the range hood. Data following the intervention will be collected for an additional one week.
