Abstract :Aim: The aim of this study is to compare the levels of lumbar 1 - lumbar 4 total, femoral neck bone mineral density, calcium, phosphorus, alkaline phosphatase, parathyroid hormone and vitamin D values which are routinely used to evaluate bone health by age. Methods: We retrospectively reviewed 713 patients over the age of 40 who underwent dual-energy x-ray absorptiometry. Patients with secondary osteoporosis were excluded. A total of 106 patients were included in the study. The patients were divided into four groups according to their ages: Group 1; 11 patients, 40-49 years, Group 2; 42 patients, 50-59 years, Group 3; 34 patients, 60-69 years and Group 4; 10 patients, 70-79 years. Lumbar 1–lumbar 4 total and femoral neck bone mineral density, calcium, phosphorus, alkaline phosphatase, parathyroid hormone and vitamin D values were extracted from the patient files and recorded. We examined the relationships between the groups. Results: Calcium, lumbar 1 - lumbar 4 total and femoral neck bone mineral density were statistically significant between the groups; the highest calcium value was observed among group 4 patients, and the comparison between the groups was statistically significant. There was no difference, in vitamin D, phosphorus, alkaline phosphatase and parathyroid hormone levels between the groups. Vitamin D levels were low in all groups. Discussion: Vitamin D levels were low in all groups. Older adults also observed low bone mineral density (BMD) and high calcium levels. Conclusion: Lower bone mineral density in patients with advanced age was as expected. In addition, a high calcium value was observed in this group; this result may be thought to be due to the immobilization of elderly patients.
