The purpose of the study is to investigate the occupational difference of Vitamin D deficiency according to the level of physical activity and the level of stress. For this purpose, We performed empirical approaches and adopted KNHANES 2008~2013 dataset, to which were applied such methods as crosstabulation analysis, logistic regression and SOBEL test. As a result, we found that Vitamin D deficiency was higher in the group of people with indoor-working-job than in the group of people with out-door working job. Besides, Vitamin D deficiency tends to increase in the people with lower physical activity and higher stress experience. As a result, those employees highly related with in-door activities must be ensured that they need to be exposed to sunlight on a regular basis. Moreover, improving the physical activity levels of employees could be one of appropriate solutions to alleviate Vitamin D deficiency problems. Besides, lowering stress levels in workplace needs to be seriously considered in order not to drop the physical activity levels of workers.
