Vitamin D Status and Its Association with Parathyroid Hormone Concentration in Brazilians

الملخص EN

Vitamins are organic compounds that play a vital role in the control of metabolic processes.

The D complex is considered a nutrient with a hormonal action and has an important participation in the constant maintenance of serum and extracellular calcium levels.

The present study aims to analyze the results of 105.588 vitamin D (25(OH)D) measurements obtained from a database from a clinical analysis laboratory in Brazil, between the years of 2011 and 2013.

The values of 25(OH)D were correlated with age, gender, and values of PTH.

The results show a high prevalence of values of 25(OH)D considered inadequate, characterizing 76% of the studied population.

It was observed that 26,5% of the individuals had deficiency and 49,5% had insufficiency of vitamin D.

It was also shown that there was a negative correlation between 25(OH)D and PTH levels.

In conclusion, this study is in accordance with others that show a high prevalence of vitamin D deficiency in different populations and alerts us for the importance of these measurements and analysis in clinical practice and as a base for diagnosis and treatment of hypovitaminosis.
