| Abstract: | Respiratory effects of ozone in the workplace have not been extensively studied. Our aimwas to explore the relationship between daily average ozone levels and compensated acuterespiratory problems among workers in Quebec between 2003 and 2010 using a time-stratifiedcase-crossover design. Health data came from the Workers’ Compensation Board. Dailyconcentrations of ozone were estimated using a spatiotemporal model. Conditional logisticregressions, with and without adjustment for temperature, were used to estimate oddsratios (ORs, per 1 ppb increase of ozone), and lag effects were assessed. Relationshipswith respiratory compensations in all industrial sectors were essentially null. Positivenon-statistically significant associations were observed for outdoor sectors, anddecreased after controlling for temperature (ORs of 0.98; 1.01 and 1.05 at Lags 0, 1 and 2respectively). Considering the predicted increase of air pollutant concentrations in thecontext of climate change, closer investigation should be carried out on outdoorworkers. |
