||Adult-onset asthma and wheeze among irritant-exposed bleachery workers
||May 2003, Vol.43, No.5, p.532-538. 25 ref.
||It is unclear whether new-onset asthma is associated with irritant exposure. This study investigated if occupational exposure to irritant gases, especially repeated peak exposure (gassings), increased the risk of obstructive airways disease. Data on airway symptoms and exposure among 101 bleachery and 314 paper department workers of a pulp mill were collected by a questionnaire. Incidence rates and hazard ratios (HR) (Cox regression) were calculated . The incidence rate for adult-onset physician-diagnosed asthma among bleachery workers reporting gassings giving rise to respiratory symptoms was 7.6/103 person-years and for those without gassings 2.2/103 person-years, compared to 1.0/103 person-years for paper workers. In a Cox regression model for asthma, stratified for sex, HR for gassings were 5.6, for hay fever 3.0, and for ever smoking 0.7. The same model for adult-onset wheeze gave HR of 5.2, 1.7, and 1.1, respectively. Repeated peak exposure to irritant gases in the pulp industry increased the risk for both adult-onset asthma and wheeze.
