Associations between home environment factors and respiratory symptoms, and reported allergiesamong junior high school students in Kobe, Japan (N¼1048) were investigated in the present study.These were mutually adjusted for age, sex, type of school (private/local) and their significant exposuresto the environment. Totally 13.4% of students reported to have doctor’s diagnosed asthma, 9.9% hadwheeze and 50.1% had attacks of daytime breathlessness during past 12 months, 25.7% of studentsreported that they had pollen allergy, 8.8% had cat allergy and 6.1% had dog allergy. Totally 29.4% ofstudents were living in a wooden house and during past 12 months, 18% of students reported that theirhomes had signs of dampness, 38.2% of homes had window condensation in winter and 7.8% of homeshad indoor painting. Window condensation was associated with wheeze (odds ratio (OR)¼1.54; 95%confidence interval (CI) 1.01–2.34), daytime breathlessness (OR¼2.02; 95% CI 1.56–2.63), airway infec-tion during past 12 months (OR¼1.66; 95% CI 1.17–2.37), cat allergy (OR¼1.63; 95% CI 1.05–2.54);mould allergy (OR¼1.84; 95%CI 1.08–3.12) and pollen allergy (OR¼1.54; 95% CI 1.15–2.06). Recentindoor painting was associated with daytime breathlessness (OR 1.83; 95% CI 1.12–3.00), dog allergy(OR¼2.23; 95% CI 1.02–4.85) and mould allergy (OR¼2.43; 95% CI 1.14–5.17). Living in a wooden housewas associated with dog allergy (OR¼2.17; 95% CI 1.18–4.00) and mould allergy (OR¼1.98; 95% CI1.04–3.76). In conclusion, in Japanese homes, the window condensation in winter, recent indoor paint-ing and living in a wooden house could contribute to the increased risk of respiratory symptoms andallergies for young Japanese school children.
