Air Pollution Increase Risk of Chronic Lung Disease
A new study from the Institute of Cancer Epidemiology of the Danish Cancer Society in Denmark states that long-term pollution exposure although still in low levels can increase the risk of COPD. Previous studies found an association of high exposure to air pollution and COPD.
“This findings is important for all parties and is noteworthy,” said lead researcher Zorana Andersen, a post-doctoral at the Institute of Cancer Epidemiology of the Danish Cancer Society.
Andersen and his team analyzed data to compare the exposure to air pollution and incidence of COPD in more than 52,000 people, with an age range of 50-64 years old, who lived in the two big cities in Denmark, Copenhagen and Aarhus. They found a strong relationship between long-term exposure to low levels of air pollution and COPD. This relationship has already taking into account of smoking habits and other factors that influence the risk CPOD.
The strongest relationship is seen in people with diabetes and asthma. Stronger linkages occur in men, fat people, and those who ate less than 240 grams of fruit per day.
“These results reinforce the conclusion of air pollution is a causative agent in the development of COPD,” said Andersen. This study will be published in the American Journal of Respiratory and Critical Care Medicine.
