Bone health assessment method, device and storage mediumTechnical Field
The invention relates to the technical field of health state evaluation, in particular to a bone health evaluation method, a bone health evaluation device and a storage medium.
Background
With the acceleration of aging of the population, osteoporosis has become a major disease afflicting the elderly population. About 2 hundred million people worldwide suffer from osteoporosis, and the incidence rate of the osteoporosis is the seventh most common disease and frequently occurring disease. Investigation showed that in the population over 50 years old, women had 4 times the chance of osteoporosis and 2 times the chance of bone loss. In addition, the incidence of osteoporosis increases 3-fold after 70 years of age in females and 2-fold after 80 years of age in males. The probability of osteoporosis in women is higher than the sum of the probabilities of other gynecological-specific diseases such as breast cancer, ovarian cancer and endometrial cancer. Therefore, the difference in sex gradually increases with age, and the difference in bone mass gradually increases. Gender considerations are required when considering the bone mass of a patient.
In order to make the bone of the patient healthier, the patient needs to do more exercises, and the exercises can increase local blood circulation and strengthen muscle strength. However, in order to avoid the problem of fracture during exercise, the exercise time needs to be controlled, so that the patient can exercise safely and strengthen physique. The patient can prevent or avoid fracture by strengthening daily bone health protection according to the estimated bone health condition, which is a problem to be solved by the person skilled in the art.
