This study was supported by the Services Fédéraux des Affaires Scientifiques, Techniques et Culturelles, Programme d'appui scientifique à la protection des travailleurs grant SSTC PS/10/44.
The aim of this study was to investigate the socioeconomic outcomes of subjects who experienced workrelated asthma symptoms in the absence of demonstrable occupational asthma (OA) and to compare these outcomes with those found in subjects with documented OA.
Subjects (n=157) who were being investigated for workrelated asthma, were surveyed. Of these 86 had OA, ascertained by a positive specific inhalation challenge (SIC), and 71 subjects had a negative SIC response. After a median interval of 43 months (range 12–85 months), the subjects were interviewed to collect information on employment status, income changes, and asthmarelated work disability.
Rates of work disruption and income loss at followup were similar in subjects with negative SIC (46% and 59%, respectively) and in those with OA (38% and 62%). The median loss as a percentage of initial income was 23% in subjects with negative SIC and 22% in subjects with OA. Asthmarelated work disability, defined as any job change or work loss due to asthma, was slightly more common in subjects with OA (72%) than in those with negative SIC (54%).
This study shows that, even in the absence of demonstrable occupational asthma, workrelated asthma symptoms are associated with considerable socioeconomic consequences.
