Vitamin D levels in men and women
Median vitamin D levels were similar in men and women in the whole group (Table 1). the frequency of vitamin D deficiency was not different in women (59.2%) and men (55.4%) groups (p=0.660).
Male subjects within an age group 18-29 years, 39-39 years, and over 80 years have higher vitamin D levels compared to the women group at the same age (p <0.001, p <0.001, p=0.010 respectively) (Table 3).
The frequencies of vitamin D deficiency and insufficiency according to gender are shown in Table 4. The frequency of deficiency was higher both in the female and male groups than in the insufficiency (p<0.001) and sufficient groups (p=<0.001).
