Vitamin D levels according to age
The lowest median 25(OH)D level was 14.6 ng/mL (min-max: 0.8-945 ng/mL)
in subjects aged between 18 and 29 years. The highest median 25(OH)D
level was 19.5 ng/mL (min-max: 0.3-623 ng/mL) in subjects in sixth
decade 19.5 ng/mL (min-max: 0.3-623 ng/mL), and seventh decade 19.4
ng/mL (min-max: 0.3-647 ng/mL). The lowest median vitamin D levels were
observed in the twenties and thirties, which was statistically
significant compared with the 60-69 and 70-79 years group (p=0.001)
(Table 1).
Although the highest vitamin D deficiency rates observed in 18-29 years
and 30-39 years, the prevalence of vitamin D deficiency (p=0.240), and
insufficiency (p=0.970) were not statistically significant among the age
groups (Table 2).
