Asthma risk greater for smokers
Study Findings:
- Current smokers are 33% more likely to develop asthma. People who had given up smoking are 49% more likely to develop asthma than those who never smoked.
- The risk of asthma was proportional to the number of cigarettes smoked each day - and the total number smoked during a lifetime so far.
- Female smokers and ex-smokers had an increased risk of developing asthma of between 138% and 143%.
Method:
- 521 participants who started to show signs of developing asthma were then monitored over two-and-a-half years, and compared to 923 people with no signs of the allergy.
Amanda Sandford, of the charity Action on Smoking and Health, said: “This is an important study showing conclusively that tobacco smoke can trigger asthma in adults whether or not they smoke. It provides yet more evidence of the need for legislation to make all workplaces and public places smoke-free.”
