Bar workers' better lung function post ban

|

DUNDEE, Scotland, Oct. 11 (UPI) -- Scottish bar workers showed significant improvement in respiratory and lung function within two months following a ban on smoking in confined public places.

Daniel Menzies and colleagues from Ninewells Hospital and Medical School in Dundee, Scotland, examined the effect of the recently introduced smoke-free legislation on bar workers' health in Scotland.

The study, conducted in Tayside, Scotland, from February to June 2006, initially included 105 non-asthmatic and asthmatic non-smoking bar workers, of whom 77 completed the study.

The researchers found that a total of 79.2 percent of the bar workers experienced respiratory or sensory symptoms before the introduction of the smoke-free policy, whereas one month afterward 53.2 percent reported symptoms, a decline of 26 percent.

At two months after introduction of the smoke-free policy, this improvement was maintained, with 46.8 percent of participants reporting a symptom -- a decrease of 32.4 percent from baseline, according to the study published in the Journal of the American Medical Association.
