Regular walking activity amount (walking bout step count, walking duration) and intensity (90thpercentile (P90) and average walking speed) was measured at baseline for seven days                      <jats:italic>via</jats:italic>                      single wearable devices. Residential concentrations of particulate matter<2.5µm (PM                      <jats:sub>2.5</jats:sub>                      ), black carbon (BC), nitrogen dioxide (NO                      <jats:sub>2</jats:sub>                      ) and ozone (O                      <jats:sub>3</jats:sub>                      ) were estimated using land-use regression models for the previous two years. Moderate-to-severe exacerbations over a two-year follow-up were obtained from medical records and paper diaries. We estimated the interaction between walking activity and air pollution on long-term exacerbation rate with multivariable mixed-effects negative binomial models.                    </jats:p>
