RESUMEN
Osteoporosis is a disease in which the density of bone is decreased with consequent increase in bone fragility and susceptibility to fracture risk. Vitamin D deficiency may cause secondary hyperparathyroidism and low bone mineral density. Our study was aimed to assess relation between vitamin D status and parathyroid hormone and bone density in adults. Relatively healthy 369 participants aged between 20-60 were randomly selected from Ulaanbaatar city. Specially designed questionnaire was used in the survey. Bone mass density was diagnosed according to the WHO criteria by the T-score. Respondents serum calcium and phosphorus levels were described by the fully automated analyzer (Cobas Integra 2800, Germany). Serum parathyroid hormone and 25-hydroxivitamin D levels were described by using ELISA kit (Eucardio Laboratory, Inc. USA) at the Molecular biology laboratory of MNUMS.The statistical result was analyzed by SPSS 21 program. The subjects mean age was 47.61±12.92, with a range of 20-83. The mean T-score was -0.60±2.17. Our study showed that negative correlation between bone mass density values at parathyroid hormone (r=-0.58, p<0.05), 25-hydroxyvitamin D (r=-0.48, p<0.05) and serum calcium (r=-0.21, p<0.05). Our study showed increased serum parathyroid hormone led the releasing calcium from bone and decreasing bone mass density.
