Vitamin D Deficiency, Smoking, and Lung Function in the Normative Aging Study (original) (raw)

Vitamin D deficiency (VDD) can influence lung function, particularly in smokers. This study, using data from the Normative Aging Study, suggests that maintaining vitamin D levels above 20 ng/ml may help mitigate lung function decline in smokers. The research indicates that both the presence of VDD and a significant smoking history contribute negatively to lung function outcomes. Further investigation through interventional studies is recommended to explore vitamin D supplementation as a potential strategy to protect lung function in this demographic.
