BANNING smoking in public places has cut hospital admissions for childhood respiratory infections in England by almost 4%, new research from Edinburgh University has shown.
Researchers say the findings confirm that anti-smoking legislation is making a significant impact on child health and should be implemented worldwide.
The team looked at the number of children under 15 who were admitted to hospital in England between 2001 and 2012 with respiratory infections – which include chest, nose, throat and sinus infections. More than 1.6 million cases were analysed.
Following the introduction of the smoking ban in 2007, the total number of children requiring hospital attention for respiratory infections dropped immediately by 3.5%, the study found.
The biggest effect was seen in the number of those suffering chest infections, which fell by almost 14%.
The number of admissions attributable to nose, throat and sinus infections also dropped, but the effects were more gradual, the findings revealed.
Researchers compared the figures to mathematical predictions of the number of admissions that would have occurred without the ban.
They estimate that almost 55,000 cases were averted – around 11,000 per year.
Less than one sixth of the world’s population is currently protected by robust anti-smoking laws. Around 40% of children around the world are regularly exposed to second hand smoke.
Professor Aziz Sheikh, Co-Director of the Centre for Population Health Sciences said: “The many countries that are yet to enforce smoke-free legislation should consider the substantial number of hospital admissions from respiratory infections that occur each year that they delay.”
