The aim was to investigate the prevalence of oropharyngeal carriage of Streptococcus pneumoniae , Haemophilus influenzae , Moraxella catarrhalis , Neisseria meningitidis and beta‐haemolytic streptococci among asthmatic and non‐asthmatic young Finnish men and to identify putative risk factors. Objectives: A total of 224 asthmatics and 668 non‐asthmatic men (mean age 19.6 years) from two intakes of conscripts to the Kainuu Brigade, Finland in July 2004 and January 2005 were enrolled upon entering military service. Methods: Oropharyngeal specimens were examined for bacteria by routine culture methods. All the participants filled in questionnaires concerning risk factors for asthma and respiratory infections. Results: S. pneumoniae (48 cases, 5.4%), Group A streptococci (16, 1.8%), H. influenzae (45, 5.0%), M. catarrhalis (24, 2.7%) and N. meningitidis (20, 2.2%) were isolated from the 892 participants. Ten putative risk factors for oropharyngeal colonization (asthma, atopy, allergic rhinitis, smoking, current use of asthma medication, history of adeno/tonsillectomy, level of highly sensitive C‐reactive protein, peak expiratory flow, results of a 12‐min running test and body mass index) were evaluated. The only significant risk factor for S. pneumoniae carriage was asthma (OR, 2.04; 95% CI 1.12 to 3.72). Conclusions: Pneumococcal carriage is more common in asthmatic than in non‐asthmatic young men.
