Bacground:Occupational exposure is thought to account for up to25% of all cases of adult asthma. Detailed individual level data regarding the relationship between asthma, occupation and work-related symptoms are needed in Turkey to inform policies on workplace safety. The aim of this study was to investigate the association between asthma symptoms, occupation type and workplace exposure in patients with asthma.

: In this cross-sectional, multicenter study adult asthma patients were investigated in terms of relationship between asthma symptoms and workplace exposure by a questionnaire. The study population was adult patients who had been diagnosed as asthma for at least six months prior to study and who were under follow-up in Ankara, Istanbul, Erzurum, Düzce, Trabzon,Denizli and Diyarbakır.

:Of the 345 cases (188 females), the mean age was 41±13.The majority of the patients (36.8%) were“housewives”,other common occupations were office workers(6.7%), textile workers(4%),students(3.8%),hospital staff(3.5%),cleaners(2.9%).The ratio of patients who described worsening of asthma during working periods was 35%.Among patients with a history of increased symptoms in workplace 100(83%) developed asthma after starting work while 20 patients (17%) had pre-existing asthma. Half of the patients described workplace exposure to dust, fume, and gases. Exposure to cleaning supplies at home was present in 43% of the subjects. Of all housewives 12%(n=15) described an increase in their asthma symptoms during housework. The frequency of bleach or hydrochloric acid use alone among housewives was 60%and 34%, which was significantly higher than other occupations.The FEV1/FVC ratio of housewives who frequently used hydrochloric acid(FEV1/FVC=71.5) was lower than that of non-users(FEV1/FVC=74.9) (p=0.024).

: Patients with asthma experience significant workplace exposures that exacerbate their symptoms. Housewives experience significant exposure that triggers allergic and asthma symptoms.It is important to raise both patient and physician awareness about the prevalence and risks of occupational (including inhome) exposures in asthmatics in order to minimize asthma triggers and exacerbations.
