We evaluated whether low birthweight, prematurity, and prenatal maternal smoking were associated with increased risk of invasive meningococcal disease. METHODS: We linked the Danish nationwide National Registry of Patients, the Birth Registry, and social registries to obtain data on fetal growth and social factors on 1921 cases of meningococcal disease hospitalized between 1 January, 1980 and 31 December, 1999 (median age 31 months, interquartiles 13-65 months) and 37 451 population controls. The impact of maternal smoking was examined in a subsample of 462 cases and 9240 controls born after 1990, when data on smoking became available in the Birth Registry. RESULTS: The adjusted odds ratios (OR) of meningococcal disease associated with low birthweight (\textless2500 g) varied between 1.6 (95\% CI: 1.1, 2.3) in infants \textless12 months to 1.5 (95\% CI: 1.0, 2.3) in children \textgreater60 months of age at hospitalization for meningococcal disease. Premature children had an increased risk of meningococcal disease during the first year of life only (adjusted OR = 1.3, 95\% CI: 1.1, 1.9). The effect of low birthweight was very similar among mature and premature children. The adjusted OR for maternal smoking was 1.8 (95\% CI: 1.4, 2.2). CONCLUSIONS: Low birthweight is associated with an increased risk of meningococcal disease throughout childhood, while an effect of prematurity persists only for 12 months. Maternal prenatal smoking was associated with the risk of meningococcal disease.
