Vitamin D May Protect Lung
Function in Smokers An important new study at the Channing Laboratory, Brigham and Women’s Hospital confirms Vitamin D deficiency is associated with rapid decline in lung function over time in smokers; The research suggests that the “sunshine” vitamin may also help protect against the effects of smoking on lung function.
The researchers examined the relationship between vitamin D deficiency, smoking, lung function, and the rate of lung function decline over a 20 year period in a cohort of 626 adult white men from the Normative Aging Study.
The findings were published online in the American Thoracic Society‘s American Journal of Respiratory and Critical Care Medicine.
In the study, vitamin D levels were assessed at three different time points between 1984 and 2003, and lung function was assessed using specialized analytical equipment.
“Our results suggest that vitamin D might modify the damaging effects of smoking on lung function,” said the researchers, adding… “These effects might be due to vitamin D’s anti-inflammatory and anti-oxidant properties.”
“If these results can be replicated in other studies, they could be of great public health importance,” they emphasized “Future research should also examine whether vitamin D protects against lung damage from other sources, such as air pollution.”
“While these results are intriguing, the health hazards associated with smoking far outweigh any protective effect that vitamin D may have on lung function ,” said Alexander C. White MS, MD, chair of the American Thoracic Society’s Tobacco Action Committee.
“First and foremost, patients who smoke should be fully informed about the health consequences of smoking and in addition be given all possible assistance to help them quit smoking.”
