Abstract
Karvonen M (Department of Epidemiology and Health Promotion, National Public Health Institute, Elimäenkatu 25, SF-00510 Helsinki, Finland), Tuomilehto J, Pitkäniemi J, Naukkarinen A and Saikku P. Chlamydia pneumoniae IgG antibody prevalence in south-western and eastern Finland in 1982 and 1987. International Journal of Epidemiology 1994; 23: 176–184. Chlamydia pneumoniae lgG antibody prevalence was examined in a representative sample (2342 subjects) of the population aged 25–59 years in south-western and eastern Finland in 1982 and 1987. Microimmunofluorescence was used to measure lgG antibodies. Prevalence of C. pneumoniae was modelled using the GLIM statistical package assuming that the prevalence had a binomial distribution. The prevalence was assumed to be a function of the year, subjects' gender, age and place of residence. The effect of the year on the prevalence was significant in both regions (PPC. pneumoniae infection in the south-west is consistently higher than in the east, or there was an outbreak of C. pneumoniae infection in both the years we examined. Thus it is more likely that the high prevalence in south-western Finland was connected more with the epidemics reported elsewhere in Scandinavia in the same years than with the occurrence of C. pneumoniae infection in eastern Finland.Keywords
