clear which cleaningrelated exposures induce or aggravate asthma. Methods Risk factors for …

Rationale: Occupational exposures to vapors, gas, dust, or fumes have been shown to be a
risk factor of airway obstruction in cross-sectional studies in the general population. …

We assessed the association between occupational exposures and symptoms of chronic
bronchitis and pulmonary ventilatory defects in a general population-based study of five areas …

We assessed the association of asthma prevalence in young adults with susceptibility factors
and environmental exposures, taking into account the age at asthma onset. A random …

The objective was to measure the incidence of asthma and its determinants in Spain, where
the prevalence of asthma is low to medium. A follow-up of subjects participating in the …

Fine particulate matter (PM 2.5 ) was sampled at 5 Spanish locations during the European

The follow-up of cohorts of adults from more than 20 European centres of the former
ECRHS I (1989–1992) investigates long-term effects of exposure to ambient air pollution on …

The aim of our analysis was to study the association between air pollution and asthma among
adults. For this goal, a previously developed “asthma score” was used. Persons aged 25–…

Background: Previous cross-sectional studies have shown that job change due to breathing
problems at the workplace (respiratory work disability) is common among adults of working …
