Introduction: A number of epidemiological studies have shown a significant association between asthma and work as cleaner but reporting schemes and workforce surveys have identified typical features of occupational asthma in only a small minority of cleaners. This discrepancy is due either due to under-reporting by clinician; misattribution of work-exacerbated asthma or other respiratory disease by the epidemiological studies, or the development of occupational asthma with atypical symptoms that make it identifiable epidemiologically but difficult to diagnose clinically. Hypothesis: The study hypothesis is that cleaners’ asthma is induced by chronic low-level irritant exposures that gradually induce airway hyper-responsiveness but do not cause work-related airway constriction/symptoms. It is thus identified by epidemiologists but is not easily identifiable clinically. Aim: The aim of this PhD is to identify the proportion of cleaners with feature of occupational asthma and to identify risk factors for cleaners’ asthma.
