Abstract:
BACKGROUND: Osteoporosis is becoming major health problem in old age and menopausal women, and osteoarthritis is most common joint disease in both ages. The inverse relationship between osteoporosis and osteoarthritis was first noticed 20years ago. However the subject had not been studied in korea. Thus, our objectives is to examine the influence of osteoarthritis on bone density measurements. METHODS: The study group consisted of 120 women, aged over 40 years, who visited for health examination in Health Center of Poondang Jesaeng general hospital from October 1998 to April 1999. Bone mineral density(BMD) of the lumar spine was measured, using dual energy X ray absorptiometry(Lunar, Expert XL), and lateal lumbar spine radiograph was taken. Severity of osteoarthritis were scored on osteophytes, disk space narrowing and vertebral body sclerosis. RESULTS: Postmenopausal women had signifcantly lower BMD than premenopausal women(p<0.001). Age(r= 0.545, p<0.001), body mass index(r=0.264, p<0.01) and education(r=0.284, p<0.01) were significantly correlated with BMD, but smoking, exercise, radiogrphic OA variables not correlated. However, stepwise multiple regression analysis using osteoporosis related variables and OA variables is indicated that menopausal status, body mass index, age, osteophytes were significantly associated factor with BMD, and lumbar osteophytes explained 2.7% of variation in lumbar spine BMD. CONCLUSION: We conclude that, among women, lumbar BMD is highier in those with osteophytosis of the lumbar spine. The effect is largely directed by osteophytes being included in the BMD measurement.
