Exposure to secondhand smoke greatly enlarge a child's chances of developing several invasive bacterial diseases, according to a new appraisal of published studies. The risk was found to be particularly strong for children 6 years old and younger. Exposure to secondhand smoke double the risk for enveloping meningococcal disease, the analysis found, and may also enlarge the chances of developing invasive pneumococcal disease and Haemophilus influenza type B. The result, which came from an analysis of 42 studies, most conduct in high income countries with good immunization policies, are published online in PLoS Medicine.
The results suggest that decreasing children's experience to secondhand smoke could decrease the number of illness and deaths caused by these diseases, particularly in poor countries with low rates of vaccination against enveloping bacterial diseases, according to study author Chien Chang Lee of the Harvard School of Public Health and fellow researchers. "Because the burden of invasive bacterial disease is top in developing countries where secondhand smoke is rising, there is a need for high quality studies to prove these results and for interventions to decrease exposure of children to secondhand smoke," they said in a journal news release.
