OBJECTIVE: To determine whether an association exists between passive exposure to tobacco smoke and bacterial meningitis in childhood, in an Australian population.
METHODOLOGY: A retrospective, case-controlled telephone survey of the parents of 71 children admitted to the Women's and Children's Hospital, North Adelaide, with bacterial meningitis between 1990 and 1999.
RESULTS: The annual incidence of Haemophilus influenzae type b (Hib) meningitis decreased significantly during the study period (11.0 cases per year 1991-93 and 1.5 cases per year 1994-99, Fisher's exact test; P < 0.001) whilst pneumococcal cases significantly increased (2.3 cases per year 1991-93 and 4.9 cases per year 1994-99, Fisher's exact test; P < 0.001). Although comparable numbers of cases and controls came from smoking families (41% vs 45%), more cases came from bi-parental smoking households (17% vs 8%; odds ratio (OR) = 2.20, 95% confidence interval (CI) 0.77-6.24) and cases were more likely to live in households where parents smoked inside (27% vs 13%; OR 2.51, 95% CI 1.05-6.03). In households where parents smoked, children who had had meningitis were significantly more likely to have parents who smoked inside the house, than children who had not had meningitis (66% vs 28%, Fisher's exact test; P = 0.005).
CONCLUSION: This study suggests there may be an association between high levels of passive exposure to tobacco smoke and bacterial meningitis in Australian children. A study with larger numbers of affected children which quantifies passive exposure to tobacco smoke is needed to determine the strength of this association.
