N95 Masks for Lung Health While Golfing During Wildfire Season

Lung health is negatively affected during wildfire season by increased smoke pollution. Wearing N95 masks protects lung health in the short-term. The purpose of our study is to assess whether wearing of N95 facemasks on days with moderate to high air pollution in people who go outside to golf on a regular basis (two or more times per week) for two months during the wildfire season projects lung health.

About this study

Wildfire smoke negatively affects lung health. Across North American, millions of people are exposed to wildfire smoke most summers. The purpose of our study is to determine whether people who golf regularly (two or more times per week) can use N95 masks to protect their lungs from wildfire smoke. Forty regular golfers will be randomized to receive N95 masks or not to receive masks. All participants will be told to follow guidelines for outdoor activity based on Air Quality Health Index readings. Those randomized to wear N95 facemasks will be asked to wear these on days they golf where Air Quality Health Index indicates moderate risk or higher. The main outcome is compliance with wearing the N95 mask. Secondary outcomes include changes in lung function, blood pressure, and respiratory symptoms over two months.

Treatment and study plan

N95 mask

Device

N95 mask to be worn outside when golfing when Air Quality Health Index reading indicates moderate risk or higher

Primary outcomes

  1. Change in compliance with wearing of N95 masks (number of times divided by days with moderate or higher air pollution)

    Time frame: 8 weeks

    compliance with wearing the N95 masks

Secondary outcomes

  1. Change in forced expiratory volume in one second (L)

    Time frame: 8 weeks

    Force expiratory volume in one second measured with spirometry

  2. Change in forced vital capacity (mL)

    Time frame: 8 weeks

    Forced vital capacity measured by spirometry

  3. Change in forced expiratory flow at 25% to 75% of vital capacity (mL)

    Time frame: 8 weeks

    forced expiratory flow at 25% to 75% of vital capacity measured by spirometry

  4. Change in respiratory symptoms (score out of 12)

    Time frame: 8 weeks

    Respiratory symptoms determined by the Dyspnoea-12 questionnaire

  5. Change in systolic blood pressure (mmHg)

    Time frame: 8 weeks

    Systolic blood pressure measured by an automatic sphygmomanometer

  6. Change in diastolic blood pressure (mmHg)

    Time frame: 8 weeks

    Diastolic blood pressure measured by an automatic sphygmomanometer
