Correlation analysis of DXA and combined use of QUS and OSTA

摘要

Background: At present, the population aging situation in China has become more and more serious. Osteoporosis is one of the deadliest diseases that affect the health of the elderly. Early detection and early prevention of osteoporosis can help to avoid serious complications of osteoporosis, such as limb brittle fractures or vertebral compression fractures. The extended life expectancy and increasing number of elderly in the population means the arrival of an aging society. Quantitative ultrasound (QUS) is a non-invasive method for evaluating bone mass density developed in the 90s. It not only reflects the bone density, but also contributes to show the bone strength and bone structure characteristics; therefore, it has the value of diagnosing osteoporosis and predicting potential fracture risks as well. At the same time it is convenient to carry and easy to operate. Asian osteoporosis self-assessment tool (OSTA) is an easy and effective way to evaluate Asian people's osteoporosis. Neither OSTA nor QUS can solely achieve the desired sensitivity and specificity when screening for osteoporosis, but it is a feasible way to combine both methods. This study aims to explore the use of combining QUS and OSTA to evaluate the risk of osteoporosis in a community of postmenopausal women.
