Osteoporosis and osteoporotic fractures are diseases that seriously affect the health of middle-aged and elderly people, becoming a public health problem that needs to be faced in an aging society. In order to prevent and treat these diseases scientifically, the Chinese Medical Association (CMA) Branch of Osteoporosis and Bone Mineral Diseases released the “Guidelines for the diagnosis and treatment of primary osteoporosis (2011)” on the 13th. Professor Xu Ling, director of the Chinese Medical Association’s Osteoporosis and Bone Mineral Diseases Branch, said that osteoporosis is a common but hidden disease, and patients are not aware of the “quiet” treatment of osteoporosis until after a fragility fracture occurs, and the fundamental goal of preventing and treating osteoporosis is to prevent fractures. A major feature of the new guidelines is the emphasis on identifying target populations at high risk of fracture without fracture through “osteoporosis risk assessment”. Professor Lin Hua, deputy director of the Chinese Medical Association’s Osteoporosis and Bone Mineral Diseases Branch, pointed out that, according to relevant statistics, the cost of treating hip fracture in China’s medical expenses in 2005 was as high as 8.5 billion yuan, and the cost of hip fracture surgery alone could reach 20,000 yuan per capita. “Through scientific and effective ‘osteoporosis risk assessment’, improving the consultation rate of osteoporosis patients and reducing the incidence of osteoporosis fractures can not only improve the quality of life of osteoporosis patients, but also save patients’ medical expenditures and social medical security resources.” ”To prevent osteoporosis, you must start in young adulthood and store more bone mass by cultivating a good lifestyle when you are young, so that when the bone mass changes due to age you can have sufficient capital to supply what you need.” Xu Ling said that in addition to more sunshine, more calcium-containing foods, such as milk, shrimp, kelp, sesame paste, etc., but also adhere to outdoor exercise, quit smoking and alcohol, and regular monitoring of bone density if possible. Experts point out that outdoor activities are better from 9 to 10 a.m. and 2 to 5 p.m., because the light is good for calcium absorption and the temperature is not too low. If you really suffer from osteoporosis, you don’t have to be too nervous. The risk can be minimized as much as possible through long-term rational medication. According to the national large-scale epidemiological survey in 2006, it was estimated that about 69.44 million people over the age of 50 suffered from osteoporosis, over 200 million people had low bone mass problems, and the total prevalence of osteoporosis was higher in women than in men.
