Introduction:

Vitamin D is involved in bone-mineral metabolism, diabetes mellitus, immunological diseases, tumor processes, cardiovascular system, anemia, etc.

Aims:

To evaluate the prevalence of vitamin D insufficiency- deficiency and its associated risk factors in hemodialysis patients.

Results:

Only 5.88% of patients presented normal levels. 94.14% of patients had levels below 30 ng/ml (mean 9.64 ng/ml). In this last group, patients were older, less exposed to the sun and used sun protection. A greater presence of women was found, taking less vitamin D or VD enriched foods and fewer statins. Between them, three patients had insufficient weight. The two black patients had levels < 10 ng/ml. In our geographical situation [Latitude: 41° 09’22”N], in winter, vitamin D skin-synthesis is scarce. Only 14.12% of patients took any vitamin D supplementation. Only one variable was statistically significant (human race). We must consider that it can be attributed to our limited sample size.

Conclusions:

94.14% of patients have low vitamin D levels and pharmacological supplementation seems necessary.
