Abstract
This population-based cross-sectional survey assessed the prevalence of work-aggravated asthma symptoms and the effect of the work environment on the aggravation of symptoms of established asthma. A questionnaire was sent to 2,613 persons (aged 20–65 yrs) with asthma. The analyses were restricted to the 969 respondents who were currently employed. The effect of occupational exposure on the aggravation of asthma symptoms at work was assessed according to both self-reported and expert-evaluated exposure. Approximately 21% of the respondents reported work-aggravated asthma symptoms at least weekly during the past month. The prevalence of those with work-aggravated symptoms increased by age, self-reported occupational exposure to dusts, abnormal temperatures or poor indoor air quality, physically strenuous work, and chemicals, and expert-evaluated probability of daily occupational exposure to airborne dusts, gases or fumes. Aggravation of asthma symptoms at work is common among employed adults with asthma. Both self-reported and expert-evaluated exposure to dusts, abnormal temperatures or poor indoor air quality, physically strenuous work, and chemicals explained the significant worsening of symptoms. The findings suggest a marked role of the work environment in the aggravation of symptoms of established asthma.

Objectives: To estimate the prevalence of work related asthma and work related wheezing in United States workers. To identify high risk industries that could be targeted for future intervention. To determine the population attributable risk of work related asthma and work related wheezing. Methods: The third national health and nutrition examination survey, 1988–1994 (NHANES III) was analyzed to determine the prevalence of work related asthma and wheezing and to identify initially defined indust...

There are no population-based follow-up studies to estimate the fraction of asthma incidence that is attributable to work. In Finland, individuals with clinically well-established persistent asthma are registered for reimbursement of medication from the national health insurance scheme. We combined, at an individual level, these data with the population census data of 1985, 1990, and 1995 to estimate the attributable fraction of work in adult-onset persistent asthma. Our follow-up study covered ...

The Increasing Prevalence of Asthma The prevalence of asthma has increased sharply in the United States and around the world in the past 30 years. In the United States, data from the National Health Interview Survey show that the annual prevalence of asthma increased from 3.1% in 1980 to 5.4% in 1994. A review of studies performed in 17 countries during the 1960s and repeated in the 1990s confirms an international increase in asthma prevalence. Although the increasing prevalence of asthma is a g...

Occupational asthma (OA) can be defined as variable airways narrowing causally related to exposure in the working environment to airborne dusts, gases, vapours or fumes. There are many agents in the work-place that can induce asthma or cause substantial deterioration in pre-existing asthma. It has been estimated that 5-15% of adult-onset asthma can be attributed to occupational exposures. Hence adult patients, especially those with new-onset asthma, must be investigated with regard to occupation...

Objectives This study examined certain occupational exposures and the risk for adult-onset asthma. Methods A nested case-referent study of adult-onset asthma was performed on a random population sample (N=15 813), aged 21 to 51 years. Cases for the study included 2 groups: subjects reporting "physician-diagnosed" asthma (N=251) and a broader "asthma" group (N=362). The "asthma" group consisted of subjects with "physician-diagnosed" asthma (N=251) and subjects reporting asthma-like symptoms witho...

The purpose of this study was to estimate the risk of adult asthma in relation to certain occupational exposures. The study was designed as a case-control study in Goteborg, including 321 subjects with asthma, born between 1926 and 1970. Controls (n=1,459) were randomly selected from the same area from registers of the 1986 population. Questionnaire information was collected in 1996, and included occupational exposures and smoking habits. Odds ratios were calculated for exposure before asthma on...

Objectives This case-referent study was performed to investigate the possibility of nonspecific air pollution at workplaces increasing the risk of bronchial asthma for formerly healthy adults. Methods Seventy-nine cases of asthma, diagnosed at a lung clinic, among persons aged 20--65 years were compared with 304 referents drawn randomly from the population of the catchment area. Questionnaire information was obtained regarding occupation, exposure to suspect allergens, place of residence, smokin...

Abstract Background Age at asthma onset is associated with severity and outcomes of the disease. Objective We studied if age at asthma diagnosis is related to employment and outcomes in working career. Patients and methods A questionnaire was sent to 2613 adults with asthma in Tampere, Finland, and a follow-up questionnaire was sent after six years. Asthmatics were divided into groups based on their employment status: working full-time or work disability. Logistic regression was used to study th...

Background Asthmatics confront inconveniences in working life that make it more difficult to pursue a sustainable career, such as unemployment and work disability. Ways of dealing with these inconveniences may be career changes. More needs to be known about the backgrounds and consequences of career changes among asthmatics, especially their relation to asthma or a change in asthma symptoms. The aim of this study was to compare earlier career changes of adults with asthma who are working full ti...
