الوصف: | There is concern about the indoor environment in aircraft but few stud-ies exist on self-rated health (SRH) and respiratory symptoms among pilots. Occupational and non-occupational risk factors for SRH, respira-tory symptoms and other symptoms among commercial pilots were investigated in this thesis. One cohort study and one prevalence study were performed among pilots in one Scandinavian airline company. Fungal DNA, furry pet allergens and volatile organic compounds of microbial origin (MVOC) were measured on board. Cat (fel d1), dog (Can f1) and horse (Ecu cx) allergens were found in all dust samples and allergen levels were 27-75 times higher in aircraft with textile seats as compared to leather surfaces. The sum of MVOCs in the cabin air was 3.7 times higher than in homes in Uppsala and 2-methyl-1-butanol and 3-methyl-1-butanol concentrations were 15-17 times higher. Asper-gillus/Penicillium DNA and Aspergillus versicolor DNA were more common in aircraft with textile seats. One fifth reported SRH as poor or fair, 62% had fatigue, 46% overweight/obesity and 71% insomnia. Poor or fair SRH was associated with overweight/obesity, lack of exercise, insomnia, low sense of coherence (SOC) and high work demand. Re-covery from work was worse among those with insomnia and low social support at work. Fatigue was more common among young or female pilots and related to insomnia and high work demand. Pilots flying MD80 or Saab 2000 aircraft had less fatigue. Pilots exposed to environmental tobacco (ETS) on board had more eye symptoms and fatigue which were reduced after the ban of smoking (in 1997). Pilots with increased work demand developed more rhinitis, dermal symptoms and fartigue and those with decreased work control developed more eye symptoms. The incidence of doctors’ diagnosed asthma and atopy were 2.4 and 16.6 per 1000 person years, respectively. Pilots changing type of flight got more airway infections. Those reporting decreased work control had a higher incidence of atopy. Risk factors in the home environment included ETS, dampness or mould, window pane condensation in winter and living in houses built after 1975. In conclusion, SRH and respiratory health among pilots are associated with specific occupational and non-occupational risk factors. |
