Physician diagnoses of asthma and chronic obstructive pulmonary disease (COPD\/bronchitis)\u00a0were extracted from the Alberta administrative health database (AHDB). Welders provided task\u2010specific information at each contact. Estimates were derived for cumulative exposure to particulates, chromium, and nickel. Factors associated with time to first and recurrent events were identified by proportional hazards regression, adjusting for sex, age, and smoking.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of 1001 welders and 884 workers in electrical trades recruited, 1338 in Alberta were matched to the AHDB. Welders were more at risk of physician\u2010diagnosed COPD\/bronchitis than those in the electrical trades (HR for first report\u2009=\u20091.87; 95% CI\u2009=\u20091.27\u20132.77) but not of asthma. Times to first self\u2010report of asthma\/wheezing (HR\u2009=\u20091.58; 95% CI\u2009=\u20091.23\u20132.04) and rhinitis (HR\u2009=\u20091.29; 95%CI\u2009=\u20091.11\u20131.49) were shorter in welders. Among welders, time to physician\u2010diagnosed asthma was weakly related to cumulative nickel exposure (mg\/m<jats:sup>3<\/jats:sup>_h\/100) (HR\u2009=\u20091.08; 95% CI\u2009=\u20091.00\u20131.17).

The risk of both asthma and COPD\/bronchitis reduced with time using local exhaust ventilation. Self\u2010reported rhinitis increased with cumulative nickel exposure (HR\u2009=\u20091.00; 95% CI\u2009=\u20091.00\u20131.01).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Welders were at increased risk of COPD\/bronchitis, with risk related to cumulative dust and chromium exposure.
