Objectives: This retrospective study was conducted to evaluate the the influence of thyroid function on the prevalence of osteoporosis in Korean women in a local community.
Methods: Bone status and thyroid function were evaluated in 698 women (mean age, 57.9 years) who visited a public health center in Wonjusi between May and November. 2007. The bone mineral density of the radius was evaluated using dual energy X-ray absorptiometry (BHP-76-P, GE Lunar, USA). Patients were classified as normal, osteopenia, or osteoporosis based on T-scores. For thyroid function, they were classified as normal, hypothyroidism, or hyperthyroidism based on the free T4 level.
Results: The prevalences of osteoporosis and osteopenia in menopausal women were 85.5% and 56%, respectively. We found a significant negative correlation between bone mineral density and thyroid hormone level (r=0.11, P＜0.05).
Conclusion:The prevalence of osteoporosis and osteopenia increased with increasing age. We found that thyroid hormone level, as well as physiological age, were important factors affecting the rate of bone loss in older women. Thus, thyroid function testing and proper thyroid treatment are helpful for the prevention and treatment of osteoporosis in menopausal women.
