25(OH)D levels in the whole group
The median 25(OH)D level was 17.4 ng/mL (min-max: 0.1-945 ng/mL) in the whole group. The median 25(OH)D level was 16.6 ng/mL (min-max: 0.3-945 ng/mL) in women, 18.3 ng/mL (min-max: 0.1-905 ng/mL) in men. There was no statistically significant difference in terms of vitamin D levels between men and women in the whole group (p=0.300) (Table 1).
Vitamin D deficiency was present in 57.8% (n=408852) of the whole subjects’ blood samples measured for a year. Severe vitamin D deficiency (<10 ng/mL) was detected in 25% (n=176608) of the samples. 25(OH)D levels were over 50ng/mL in 5.5%, of the samples and 0.8% (n=5455) was over 100 ng/ml accepted as a toxic range (Table 1).
