Abstract
Background: There are studies that have demonstrated that the lack of vitamin D tends to deteriorate lung function, and consuming vitamin D supplements improves lung function and prevents many respiratory infections. However, studies on whether vitamin D and lung function are related in normal people are lacking. This study was conducted to analyze the association between serum vitamin D and each pulmonary function test (PFT) indicator in men with normal lung function.

Methods: Using the Korea National Health and Nutrition Examination Survey in 2012 and 2013, 2,440 men were included. Based on the plasma vitamin D level, the subjects were divided into two groups: a normal group with >20 ng/mL of vitamin D and a deficient group with lower levels. The basic characteristics and PFT indicators were analyzed using the chi-square and t-tests. The association between vitamin D and PFT indicators was analyzed using multiple regression analysis controlled by confounding variables.

Results: A comparison of the PFT indicators between the groups revealed that the forced vital capacity (FVC) (normal, 4.25¡¾0.02; deficient, 4.13¡¾0.01; P=0.03) and FVC% (normal, 92.19¡¾0.47; deficient, 91.16¡¾0.33; P=0.04) significantly differed between the groups. The PFT indicators that were positively associated with serum 25(OH)D were FVC (¥â=0.007, R2=0.526, P=0.0023), %FVC (¥â=0.147, R2=0.149, P=0.0032), forced expiration volume in the first second (FEV1) (¥â=0.005, R2=0.583, P=0.0166), %FEV1 (¥â=0.13, R2=0.036, P=0.0227), and FEV6 (¥â=0.006, R2=0.576, P=0.006).

Conclusion: The serum vitamin D of male adults appeared to be associated with FVC, %FVC, FEV1, %FEV1, and FEV6.
