Increase in asthma prevalence in adults in temporary housing after the Great East Japan earthquake
2020
Abstract It is unknown whether disasters such as earthquakes and tsunamis affect asthma development or exacerbation in adults. Here, we investigated whether asthma prevalence increased in those aged ≥15 years living in temporary housing after the Great East Japan Earthquake. We diagnosed asthma according to GINA guidelines in residents aged ≥15 years who were living, or had lived, in temporary housing in the city of Ishinomaki. We analyzed serum antigen-specific anti-immunoglobulin E (IgE) antibody levels to Dermatophagoides farinae (Der f), Aspergillus fumigatus, Aspergillus glaucus, Aspergillus amstelodami, and Aspergillus restrictus. The average age of the 337 inhabitants was 61.3 ± 15.8 years (men, 37.7%). The asthma prevalence was 24.9% according to respiratory specialist diagnosis. The antigen-specific IgE antibody titer against Der f, but none of the other test antigens, was significantly higher in the asthma group than in the no-asthma group (P
