The number of adults admitted to hospital for emergency treatment for asthma has fallen by nearly 1,900 a year since smokefree legislation was introduced in England. That is according to research by the UK Centre for Tobacco Control Studies which is based at the University of Bath. It found an immediate drop of 4.9% among adults in emergency hospital admissions for asthma after the ban on smoking in public places and workplaces in July 2007.
The study, funded by the Department of Health, identified emergency admissions of people over 16 for asthma every month from April 1997 to December 2010. The researchers compared those before and after the smoking ban was introduced on 1st July 2007, taking into account factors like seasonal flu and temperature.
The research, which is published in the journal Thorax this week, adds to the evidence that mokefree policies have a positive impact on health.
