Methods: This investigation is in the form of a descriptive correlational study that was performed in September 2015. The statistical population was all healthy and sedentary postmenopausal women 50-70 years old in Urmia city, Iran. Fifty-four sedentary postmenopausal women were selected as subjects and voluntarily and bona fide participated in this study. General and anthropometric characteristics of height, weight, and body mass index (BMI) in subjects were measured by wall-meter with an accuracy of one millimeter, digital scale with precision of 100 g (Beurer, Germany), and dual emission X-ray absorptiometry (DXA) (Hologic, USA) machines, respectively. Diastolic and systolic blood pressure was measured by indicator machine. Serum levels of vitamin D, parathyroid hormone, calcium, and phosphorus were measured by ELISA and Auto-analyzer (BT 1500, Biotecnica, Italy machines, respectively.
Results: The mean general, anthropometric, and physiological/laboratory variables of subjects were: age 54 yr, height 156 cm; weight 72 kg; BMI 29 kg/m2; systolic and diastolic blood pressure 76.20 and 110.70, respectively; vitamin D 25.22 ng/ml, parathyroid hormone 33.29 ng/ml, calcium 9.44 ng/ml, and phosphorus 3.26 ng/ml. Moreover, results showed that there was no significant relationship between systolic and diastolic blood pressure and vitamin D (P>0.581 and P>0.619, respectively). There was no significant relationship between systolic and diastolic blood pressure and parathyroid hormone (P>0.623 and P>0.341, respectively). There was no significant relationship between systolic and diastolic blood pressure and calcium (P>0.704 and P>0.141, respectively). There was no significant relationship between systolic and diastolic blood pressure and phosphorous (P>0.058 and P>0.357, respectively).
Conclusion: The results suggest that there is no relationship between systolic and diastolic blood pressure with serum levels of vitamin D, parathyroid hormone, calcium, and phosphorous in sedentary postmenopausal women 50-70 years old.
