We investigated the prevalence and determinants of nasopharyngeal carriage of Neisseria meningitidis in 3200 healthy children aged 1-19 years. The incidence of meningococcal carriage was, on average, 1.5%. Peak incidences were seen at age 1 year and after age 15 years. The independent determinants of meningococcal carriage included age, regular visits to youth clubs (odds ratio [OR], 2.2) and discotheques (OR, 4.3), and pneumococcal carriage (OR, 4.1).
