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

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. © 2017 juliana sálvio martins et al.
