Abstract

Background. Besides the extensive regulatory role in growing number of biologic processes, Vitamin D has been recently considered essential for lungs function as well as protective against exacerbation of chronic obstructive pulmonary diseases. We assessed the correlation between Vitamin D serum levels with pulmonary function in healthy individuals. Methods. In a cross-sectional study, healthy volunteer (n=92) participants underwent the following laboratory procedures: a blood test, a 24-hour urine collection test, and the serum level of 25-hydroxy Vitamin D before undergoing spirometry. Linear correlation coefficient was calculated to detect the association between serum level of 25-hydroxy Vitamin D and pulmonary volumes. Results. The mean age of participants was 39.95±9.98 years. 48% of participants showed different levels of 25-hydroxy Vitamin D deficiency. We recognized a consistent direct positive correlation between serum levels of 25-hydroxy Vitamin D and lung function volumes. The coefficient for forced vital capacity, forced expiratory volume in 1 second, forced expiratory flow 25-75%, and forced expiratory volume in 1 second/forced vital capacity ratio were 0.610, 0.509, 0.454, and 0.551, respectively. Conclusions. Our findings suggest correlation between higher serum levels of 25-hydroxy Vitamin D and improved pulmonary function. Accordingly, supplemental Vitamin D might significantly improve treatment response. © 2018 Maryam Moghaddassi et al.
