Abstract [en]

Risk factors for rhinitis, asthma and respiratory infections in the home environment were studied by a questionnaire survey. Totally 5775 occupants (>= 18 years old) from a stratified random sample of multi-family buildings in Sweden participated (46%). 51.0% had rhinitis in the last 3 months (current rhinitis); 11.5% doctor diagnosed asthma; 46.4% respiratory infections in the last 3 months and 11.9% antibiotic medication for respiratory infections in the last 12 months. Associations between home environment and health were analyzed by multiple logistic regression, controlling for gender, age and smoking and mutual adjustment. Buildings constructed during 1960-1975 were risk factors for day time breathlessness (OR = 1.53, 95%CI 1.03-2.29). And those constructed during 1976-1985 had more current rhinitis (OR = 1.43, 95%CI 1.12-1.84) and respiratory infections (OR = 1.46, 95%CI 1.21-1.78). Cities with higher population density had more current rhinitis (p = 0.008) and respiratory infections (p<0.001). Rented apartments had more current rhinitis (OR = 1.23, 95%CI 1.07-1.40), wheeze (OR = 1.20, 95%CI 1.02-1.41), day time breathlessness (OR = 1.31, 95%CI 1.04-1.66) and respiratory infections (OR = 1.13, 95%CI 1.01-1.26). Living in colder parts of the country was a risk factor for wheeze (p = 0.03) and night time breathlessness (p = 0.002). Building dampness was a risk factor for wheeze (OR = 1.42, 95%CI 1.08-1.86) and day time breathlessness (OR = 1.57, 95%CI 1.09-2.27). Building dampness was a risk factor for health among those below 66 years old. Odor at home was a risk factor for doctor diagnosed asthma (OR = 1.49, 95%CI 1.08-2.06) and current asthma (OR = 1.52, 95%CI 1.03-2.24). Environmental tobacco smoke (ETS) was a risk factor for current asthma (OR = 1.53, 95%CI 1.09-2.16). Window pane condensation was a risk factor for antibiotic medication for respiratory infections (OR = 1.41, 95%CI 1.10-1.82). In conclusion, rhinitis, asthma and respiratory infections were related to a number of factors in the home environment. Certain building years (1961-1985), building dampness, window pane condensation and odor in the dwelling may be risk factors.

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.
