Procedure: A sample of 250 postmenopausal women ranging in age between 45 to 80 years was selected by purposive sampling from various parts of north India (Haryana, Punjab, and Chandigarh). Anthropometric parameters (height, weight), physiological variables (systolic and diastolic blood pressure, pulse rate), hypertension (as per JNC VII criteria) and bone mineral density (using dual Energy X-ray Absorptiometry at lumbar spine L1-L4) of all the participants were recorded. Findings indicated that 40.4% women were identified with hypertension, out of which 12.8% had normal bone mineral density, 16.4% and 11.2% were osteopenic and osteoporotic respectively.
Results: Comparative analysis revealed that hypertensive osteoporotic subjects had significantly higher mean values for systolic blood pressure (142.71 vs. 127.22, p<0.001), diastolic blood pressure (92.68 vs. 82.39, p<0.001) and pulse rate (71.79 vs. 68.81, p<0.01) as compared to their normotensive osteoporotic counterparts. Results from binary logistic regression analysis revealed that in osteoporotic subjects odds of having systolic blood pressure was 2.32 (CI=1.05-5.13), for diastolic blood pressure 1.48 (CI=0.96-2.31), and for pulse rate 1.31 (CI=0.64-2.68).
Conclusion: The results demonstrated that high blood pressure is negatively associated with bone mineral density among elderly population.
