AIM to Improve Asthma: Airflow Improvements During Meal-Prep

Study Overview
=================
Brief Summary
-----------------
The investigators propose a pilot trial of kitchen ventilation in the homes of children using a youth engaged research strategy.

Detailed Description
-----------------
In this trial of children ages 6-12, children and their households will receive an intensive home kitchen ventilation intervention after one week of baseline data collection. 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, and a final week after all remaining families receive the cooking ventilation intervention, to assess for changes within each household. 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), and reported symptoms after the baseline and 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.

Design Details

Primary Purpose: Prevention
Intervention Model: Single Group Assignment
Interventional Model Description: This is a trial with a single group, where they receive the intervention following one week of baseline data collection.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Other: Intervention after One Week<br>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 week. | Behavioral: Cooking Ventilation Intervention<br>* 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.<br>|
