The most important factor for the prognosis of occupational asthma is the length of exposure with symptoms prior to removal from exposure. We wanted to identify factors, including socioeconomic status, that can influence the delay in submitting a claim to a medicolegal agency after the onset of asthmatic symptoms, and to confirm that this delay is associated with worse respiratory prognosis and...
The incidence and prevalence of occupational asthma has been extensively studied in industry settings and specialist clinics. However, it has been much less studied in the community. This study looked at the general practice notes of asthmatics in an attempt to assess the overall load of occupational asthma in the community. Eighty-six per cent of the patients with adult onset asthma in the pra...
Occupational exposure is a well-recognised modifiable risk factor for asthma, but the relationship between occupational exposure and asthma control has not been studied. We aimed to study this association among working-age adults from the European Community Respiratory Health Survey (ECRHS). Data were available for 7077 participants (mean age 43 years, 45% never-smokers, 5867 without asthma and...
Occupational asthma is the most common form of occupational lung disease in the developed world at the present time. In this review, the epidemiology, pathogenesis/mechanisms, clinical presentations, management, and prevention of occupational asthma are discussed. The population attributable risk of asthma due to occupational exposures is considerable. Current understanding of the mechanisms by...
Asthma is an important public health problem because of its increasing prevalence and associated morbidity. It is a major research issue because its aetiology is not established and the reasons for its increasing occurrence are unknown. Occupational asthma is a valuable model of asthma caused by specific environmental exposures which could be useful for a better understanding of the disease.' R...
The aim of this study was to describe changes in employment and income following a diagnosis of occupational asthma, and to determine what factors might affect these changes.
