Outcome Measures

Primary Outcomes (4)

  • Continuously-Measured Home PM2.5 (Fine Particulate Matter) Levels Prior to Intervention

    Home PM2.5 levels were measured in real-time with eLichens sensors.

    1-2 weeks

  • Continuously-Measured Home PM2.5 (Fine Particulate Matter) Levels Following Intervention

    Home PM2.5 levels were measured in real-time using the eLichens sensors

    1-2 weeks

  • Continuously-Measured Home NO2 (Nitrogen Dioxide) Levels Prior to Intervention

    Home NO2 levels were measured in real-time using eLichens sensors

    1-2 weeks

  • Continuously-Measured Home NO2 (Nitrogen Dioxide) Level Following Intervention

    Home NO2 levels were measured with eLichens sensors

    1-2 weeks

Secondary Outcomes (8)

  • Spirometry- Forced Vital Capacity (FVC)

    measured at the end of the pre-intervention interval

  • Spirometry- Forced Expiratory Volume in One Second (FEV1)

    measured at the end of the pre-intervention interval

  • Spirometry-Forced Vital Capacity (FVC)

    measured at the end of the post-intervention interval

  • Spirometry- Forced Expiratory Volume in One Second (FEV1)

    measured at the end of the post-intervention interval

  • Fractional Exhaled Nitric Oxide (FeNO)

    measured at the end of the pre-intervention interval

  • +3 more secondary outcomes

Study Arms (1)

Intervention after One Week

OTHER

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

Interventions

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 One Week
