Abstract [en]

Risk factors for rhinitis and asthma in the home environment were studied by a questionnaire survey. Parents of 4530 1-8 year old children (one parent per child) from randomly selected kindergartens in Chongqing, China participated. 70.4% were females; 47.1% had rhinitis symptoms in the last three months (current rhinitis, CR); 1.6% reported a history of allergic asthma (AA); 2.7% reported a history of allergic rhinitis (AR); 16.4% were current smokers; 50.8% males and 2.4% females were current smokers. Stuffy odor, unpleasant odor, tobacco smoke odor and dry air were associated with CR (adjustment for gender, current smoking and other perceptions of odor or humidity). Associations between home environment and CR, AR, and AA were studied by multiple logistic regression analyses, adjusting for gender, current smoking and other significant home factors. Living near a main road or highway was a risk factor for both CR (OR(95% CI): 1.31(1.13,1.52)) and AR (OR(95% CI): 2.44(1.48,4.03)). Other risk factors for CR included living in rural areas (OR(95% CI): 1.43(1.10,1.85)), new furniture (OR(95% CI): 1.28(1.11,1.49)), water damage (OR(95% CI): 1.68(1.29,2.18)), cockroaches (OR(95% CI): 1.46(1.23,1.73)), and keeping pets (OR(95% CI): 1.24(1.04,1.49)). Other risk factors for AR included redecoration (OR(95% CI): 2.14(1.34,3.41)), mold spots (OR(95% CI): 2.23(1.06,4.68)), window pane condensation (OR(95% CI): 2.04(1.28,3.26)). Water damage was the only home factor associated with AA (2.56(1.34,4.86)). Frequently put bedding to sunshine was protective for CR (OR(95% CI): 0.79(0.68,0.92); cleaning every day was protective for AR (OR(95% CI): 0.40(0.22,0.71)). In conclusion, parents' CR and AR were related to a number of factors of the home environment.

Abstract [en]

The main aim of this thesis was to evaluate associations between selected home environment factors and asthma, rhinitis and respiratory symptoms among adults from Sweden, China and northern Europe. Two studies were performed in Sweden, one in China, and one longitudinal cohort study was performed in northern Europe. Dampness/mould was common, and was a main risk factor in all studies. Other risk factors for asthma symptoms in Sweden included window pane condensation in winter, multi-family buildings constructed from 1961-1975, rented apartments, environment tobacco smoke (ETS), and living in a colder climate zone. Higher ventilation flow in Sweden was associated with less asthma symptoms. Risk factors for rhinitis in Sweden included window pane condensation, a higher moisture load, concrete slab foundation constructed before 1991, multi-family buildings constructed from 1976-1985, rented apartments and living in densely populated areas. Risk factors for rhinitis in China included window pane condensation, recent redecoration, new furniture, presence of cockroaches, pet keeping, ETS and living near a main road or highway. Frequently cleaning of the home and putting beddings to sunshine were protective factors for rhinitis in China. Other risk factors for respiratory infections in Sweden included houses with a brick façade, window pane condensation, a higher moisture load, multi-family buildings constructed from 1976-1985, rented apartments and living in densely populated areas. Furthermore, dampness and mould, and mould odour were risk factors for onset of asthma and rhinitis in northern Europe. In conclusion, indoor dampness and mould can be a risk factor for asthma and rhinitis in Sweden, China and northern Europe. Certain construction years (1961-1985), ETS, recent redecoration, new furniture, living in urban areas and exposure to traffic air pollution can be risk factors for asthma, rhinitis or respiratory infections. A high ventilation flow and daily cleaning at home can be protective.
