The prevalence of osteoporosis is high, with 200 million osteoporosis patients worldwide and more women than men. According to the World Health Organization (WHO) standards, the results of the National Health and Nutrition Examination Survey (NHANES III, 1988D1994) showed that osteoporosis seriously affects the quality of life of older adults, and that 1/2 of women and 1/5 of men over the age of 50 will experience an osteoporotic fracture in their lifetime, and once the patient has experienced the first osteoporotic fracture The risk of secondary fractures is significantly higher. China’s elderly population is the largest in the world, with 90 million people suffering from osteoporosis, accounting for 7.1% of the total population. With the process of aging, the incidence of osteoporosis is on the rise and is expected to increase to 221 million by 2050, when more than half of the world’s osteoporotic fractures will occur in Asia, with the vast majority in China. A survey of the annual incidence of osteoporosis, myocardial infarction, stroke and breast cancer in the United States in 1995D1996 showed that 1.5 million osteoporotic fractures occurred each year, including 700,000 vertebral fractures, 200,000 wrist fractures, 300,000 hip fractures and 300,000 other fractures, higher than the incidence of myocardial infarction, stroke and breast cancer.
