Abstract :Aim: The aim of our study was to determine whether women admitted to our hospital for any reason have 25-hydroxyvitamin D (25(OH)D) deficiency and to determine whether there is a difference between serum 25(OH)D levels according to age and seasons. Materials and Methods: 187,728 female patients admitted to our hospital in winter and summer between 2020 and 2024 were included in the study. Ages, serum 25(OH)D levels, month and season of the examinations were recorded. Serum 25(OH)D levels: >30 ng/ml was considered adequate, 20-30 ng/ml vitamin D deficiency, <20 ng/ml vitamin D deficiency, 11-20 ng/ml mild vitamin D deficiency, 5-10 ng/ml moderate vitamin D deficiency, <5 ng/ml severe vitamin D deficiency. SPSS 28.0 programme was used for statistical analysis and p<0,005 was considered significant. Results: In this study, serum 25(OH)D levels of 187,728 patients aged 10-99 years were evaluated and the mean level was 18,7±11,9 (3-100) ng/ml. Serum 25(OH)D level was found to be adequate in 13,6%, inadequate in 24,1%, mildly deficient in 37,5%, moderately deficient in 21,3%, and severely deficient in 3,6% of the patients. Serum 25(OH)D level was significantly (p<0,05) higher in summer-autumn season than in winter-spring season. Conclusion: 25(OH)D deficiency is a common problem in our country as well as in the world. Serum vitamin D levels are affected by seasonal transitions and may be lower in winter. Although routine screening of serum vitamin D levels is not recommended, it may be recommended to develop strategies to improve vitamin D status in all age groups as in pregnant women.
