In Westelijke Mijnstreek (WM), Midden-Limburg (ML), both The Netherlands, and Kreis Heinsberg (HS), Germany, the relationship between quality of the indoor environment and respiratory symptoms in children was studied, finally resulting in proposals for prevention of respiratory symptoms in the three regions. This paper presents the results of the first part of the study, investigating prevalences of respiratory complaints.A brief questionnaire was used to document prevalences of respiratory complaints, physicians diagnoses and treatment in about 7,000 children 5-6 resp. 7-8 years of age from HS, ML and WM, in 1995 and 1997. Prevalences of respiratory symptoms differed slightly between the regions, but there were differences in physician-diagnosed asthma and bronchitis and treatment of the children.The brief questionnaire is a useful instrument to get an overview on respiratory symptoms. Since 1995, it is used by several German Municipal Health Services for Public Health Reports. |
