A study has found that the total number of children requiring
hospital treatment because of their asthma has declined since the
introduction of the July 2007 smoking ban – prohibiting lighting up in
all enclosed public spaces such as restaurants, nightclubs, bars,
shopping centres, etc.
The Imperial College London’s analysis on NHS figures has been
published in the journal Pediatrics. They looked at admission rates
dating all the way back to April 2002 and they explain there has been
an incredible 8.9% reduction in hospital admissions following the first
12 months after the ban came into play.
Intriguingly, researchers identified that
preceding the 2007 ban there was a 2.2% rise each year in the number of
children admitted to hospital due to severe asthma symptoms that
include coughing, wheezing, shortness of breath and tightness in
the chest. Taking into account the predicted 2.2% rise annually,
researchers say that in those first 12 months, the ban had therefore
helped to decrease admissions by 12% with this decline continuing in
subsequent years and a 3.4% fall per year for the next two years. This
clearly demonstrates the positive impact the legislation is having on
health in addition to emphasising how damaging cigarette smoke actually
is.
Lead researcher Dr Christopher Millett says that the drop works out
at an estimated 6,802 fewer hospital admissions in the first three years
of the smoking legislation coming into effect.
Dr Millett spoke on the huge health benefits since the introduction
of the ban, commenting: “There is already evidence that eliminating
smoking from public places has resulted in substantial population health
benefits in England, and this study shows that those benefits extend to
reducing hospital admissions for childhood asthma. Previous studies
have also suggested that the smoke-free law changed people’s attitudes
about exposing others to second-hand smoke and led more people to
abstain from smoking voluntarily at home and in cars. We think that
exposing children to less second-hand smoke in these settings probably
played an important role in reducing asthma attacks. The findings are
good news for England, and they should encourage countries where public
smoking is permitted to consider introducing similar legislation.”
Medical Specialists Pharmacy finds Dr Millett’s comments particularly
interesting as he touches on many topics that we have previously
addressed such as the underestimated subject of second-hand (passive) smoking.
Not just displeasing because of the foul odour, second-hand smoking can
be a killer and those who do smoke need to be clued-up about this
serious matter and consider the harm they are inflicting on those around
them – in addition to themselves. Parents who are smoking inside their cars
is another factor not considered often enough and the impact this has
to their children’s health – especially if a child is asthmatic as this
is one factor that can cause their symptoms to flare-up.
Emily Humphreys, head of policy and public affairs at Asthma UK, was
happy with the findings of the study and she said: “It’s great to see
growing evidence of the positive impact of smoke-free legislation. This
is something we campaigned for, so it is particularly encouraging that
there has been a fall in children’s hospital admissions for asthma since
its introduction.”
Asthma is a long-term respiratory condition where the air passages
within the lungs become unexpectedly inflamed, narrowed and swollen.
This leads to a prevention of airflow into and out of the lungs. Asthma
attacks happen usually following a response to an allergen, cold air,
exercise, or emotional stress.
There are a predicted 5.4 million people in the UK currently receive
treatment for asthma – 1 in every 11 children and 1 in every 12 adults.
This equates to 8.8% of the total population (62 million estimated in
2010). In addition, it affects a staggering 300 million people
worldwide.
Although there is no cure, asthma can be controlled through the use
of preventer and reliever inhalers and Medical Specialists provide many
varieties of each and more information about these and how to obtain
them can be found on the Asthma and Allergies area of the website.
