Staff monitored by researchers in the University’s Asthma and Allergy Research Group were shown to have experienced significant benefits to their general health as a result of the smoking ban.
The study is the first major piece of medical research into the effects of the ban. Results of the study are published today (October 11th) in JAMA, the Journal of the American Medical Association.
The health of staff who worked in often smoky atmospheres in pubs and clubs was widely cited as one of the chief reasons for introducing the ban, which took effect on March 26th of this year.
“Our study shows that, across a number of health indicators, positive changes were evident even in the first two months following the introduction of the smoking ban, which is a very rapid change,” said Dr Daniel Menzies, Principal Investigator in the Adult Asthma and Allergy Research Group, working under the direction of the head of the group Professor Brian Lipworth.
“We were looking at bar staff with symptoms attributable to cigarette smoke, and in those two months following the smoking ban the proportion showing symptoms fell from over 80% to less than 50%.
“We also recorded reductions in levels of nicotine in the bloodstream, breathing tests showed improvement in lung function of between 5% and 10 %, and there was less inflammation in the bloodstream, a factor which inputs into areas such as cardiovascular health.
“The greatest changes we saw were within bar staff who were asthmatic, a group we specifically targetted. With these people we saw an overall improvement in their general quality of life.
“This was a comprehensive study looking at a range of factors that may be affected by the absence of passive cigarette smoke and the general conclusion is that the smoking ban does improve the health of people working in an atmosphere where previously there was a lot of smoke.”
Researchers carried out a range of tests on bar staff in and around Dundee, 77 of whom completed the study. The majority of them are full-time staff working in bars for around 30 hours per week. The average time spent working in bars was around nine years.
Those taking part in the study were subjected to tests one month before the smoking ban was implemented and then re-examined at periods of one and two months following the ban taking effect.
They were given breathing tests and a blood test to determine respiratory symptoms and levels of inflammation to the lungs and blood vessels. They were also given a quality of life questionnaire to complete.
The study was wholly funded by the University of Dundee

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
