Parathormone level and its relationships with vitamin D in persons over 50 years old

Abstract

The results of a study of the concentration of vitamin D and parathyroid hormone in 353 residents of the Republic of Bashkortostan in blood serum. The frequency of hypovitaminosis and a deficiency of 25 (OH) D in the older age groups of the population of the Republic of Bashkortostan is excessively high, the level reaches 77.1 %. The average value of parathyroid hormone was 55.1 ± 26.33 pg/ ml, vitamin D –22.57 ± 12.24 ng / ml. A negative correlation between 25 (OH) D and the level of PTH is characteristic (r = –0.144, p <0.001). Normal level of parthyrin was detected in 89.8 %, an excess in 8.8 % of the studied, which indicates the active work of the gland in conditions of cholecalciferol deficiency.
