ABSTRACT
Conclusion:
Since the research to find out preventive effects of vitamin D on chronic diseases such as cancer, hypertension, diabetes mellitus and it is already known that vitamin D reduces the risk of falls and fracture, closer follow-up of patients with vitamin D levels below 16.3 ng/mL with appropriate vitamin replacement may be important in reducing bone loss.
Results:
29.8% of the women had osteoporosis, and 45.8% had osteopenia. Forty eight women (36.6%) were reported to have severe vitamin D deficiency (25-OH-D<10 ng/mL), 38 women (%29) moderate vitamin D deficiency (10≤25-OH-D<20 ng/mL), and 22 women (%16.8) mild vitamin D deficiency (20≤25-OH-D<30 ng/mL). Only 23 of the women (17.6%) had vitamin D levels higher than 30 ng/mL. It was observed that as the vitamin D levels dropped, PTH levels increased. The threshold for 25-OH-D level was estimated as 16.3 ng/mL. A negative relation was observed between vitamin D and osteocalcin and a positive relation was observed between ALP, osteocalcin and PTH.
Materials and Methods:
The study was conducted as a cross-sectional study. Postmenopausal women were scanned with DEXA and divided into three groups as osteoporosis, osteopenia, and the control group according to the T scores. During medical visit, patients’ clothing habits, and daily sunlight exposure rates have been scored from 1 to 4 with a questionnaire. Vitamin D, Parathyroid hormone (PTH), osteocalcin, Dependent personality disorder (DPD), calcium, phosphorus, Alkaline phosphotase (ALP) levels were compared.
Objectives:
The aim of this study is to define the frequency of vitamin D deficiency in postmenopausal women and to evaluate its implications on bone metabolism. Patients, who admitted to the Ankara University Faculty of Medicine Outpatient Clinics included to the study.
