Objectives: Many research have been done to establish the factors affecting osteoporosis. We knew that the patients with chronic low back pain decrease daily activity and outdoor exercise because of pain, instability and claudication. But the correlation between duration of LBP and osteoporosis has not been studied.
Methods: Clinical study carried out in 105 cases of perimenopausal and postmenopausal women with LBP in Jaseng oriental hospital. BMD was measured using Z-score and T-score. Pearson simple correlation coefficients were estimated between BMD and the duration of LBP with other factors affecting osteoporosis such as age, age of postmenopause, duration since menopause, height, weight and BMI. Partial correlation between BMD and the duration of LBP were also estimated.
Results: BMD(in T-score) was negatively correlated with age. Duration since menopause was positively correlated with weight and BMI. Pearson simple correlation coefficient(γ) between BMD and the duration of LBP is -0.532 and partial correlation coefficient controlling for other confounding factors is -0.498.
Conclusions: The chronic LBP is the risk factor of osteoporosis. When treating women with chronic LBP over 50 yrs old, attention should be paid to osteoporosis to prevent possible complications of osteoporosis.
