Evaluation of seasonal variation of vitamin D levels according to demographic criteria

AbstractAim: Although vitamin D can be taken with nutrients, it is substantially synthesized in the skin tissue under the influence of the ultraviolet ray which comes from the sunlight. Therefore, the increase in the expression of vitamin D in the body during periods of increased sunlight can be expected. In this study, it was aimed to determine whether the change in the serum vitamin D levels of the patients who applied to Uşak Training and Research Hospital were significant according to age, gender and months of the year.Material and Methods: The serum vitamin D test results of the patients aged 0-80 who applied to the outpatient clinics of the hospital between 1 January and 31 December 2018 were retrospectively obtained from the hospital automation system. Data were analyzed using SPSS 21 software. p
