The aims were to examine prevalences as well as demographic and environmental predictors of respiratory virus antibodies in serum.
In a cross-sectional study of 18-73 year old Norwegian adults a random stratified sample (n=1512) was invited to attend an examination at an outpatient clinic.
Seven respiratory virus antibodies were assessed by the complement fixation test.
The attendance rate was 84%. The most frequent virus antibodies with titre of =1 : 8 were influenza virus type A with a population standardized prevalence of 44%, adenovirus 25% and influenza virus type B 22%. The prevalences of antibodies against parainfluenza virus type 1,2 and 3 increased with age.
Smokers compared to non-smokers had an adjusted odds ratio (OR) of 1.7 (95% confidence interval [Cl] : 1.3-2.4) for having one or more of the seven examined virus antibodies.
The presence of one or more of the virus antibodies increased from summer to winter months (adjusted OR=1.3 per month ; 95% Cl : 1.2-1.4) and it was higher in occupational dust or gas exposed smokers (adjusted OR=2.0 ; 95% Cl : 1.1-3.7) compared with unexposed smokers.
Ageing, smoking, occupational dust or gas exposure as well as season of the year may thus be predictors for levels of respiratory virus antibodies in adults.
