title: [Cohort study on respiratory diseases and lung function in schoolchildren in southwest Germany. I. study design, prevalence and incidence of respiratory diseases].
abstract: A prospective cohort study on schoolchildren was conducted during the years 1977, 1979 and 1985 in Mannheim and the Black Forest county near Freiburg to investigate the regional differences in respiratory diseases and symptoms. Each survey included a lung function test and questions on respiratory symptoms. The response rates were high (84% averaged over the years and areas). A total of 8514 children participated in the study, 2066 children took part in two and 1486 in all three surveys. Prevalence and incidence rates of 11 respiratory and allergic diseases are reported in part 1 of the publication. In further parts, prevalence will be analysed using regression techniques and a comparison in the development of lung function between the different regions will follow. In general, prevalences of the respiratory and allergic diseases were higher for boys than girls at age 8-10. In contrast, 16 year old girls were equally affected and sometimes showed higher prevalences than boys except for asthma. 1977 and 1979 higher prevalences of respiratory symptoms were found in Mannheim compared to Freiburg. Allergic symptoms occurred more frequently in the area around Freiburg. No difference in prevalence and incidence could be demonstrated for the year 1985 between the two regions.
