In 2014, the Shanghai Bureau of Statistics and the Shanghai Survey Bureau of the National Bureau of Statistics released data showing that the average life expectancy of the city’s household population reached 82.29 years, and that the aging of the population is becoming increasingly evident. In the same year, the Shanghai Civil Affairs Bureau, the Municipal Office for the Aging and the Municipal Bureau of Statistics released data showing that 28.8% of the total population in Shanghai is over 60 years old. This means that almost every large family in Shanghai has people over 60 years old. And the 2013 Blue Book on Osteoporotic Fracture Prevention in China points out that the prevalence of vertebral fractures among women over 50 in China is 15%, which is equivalent to one in seven women over 50 having suffered a spinal fracture. These statistics tell us that osteoporosis is likely to happen around you. Osteoporosis is a systemic skeletal disease in which the volume of bone units decreases, the microstructure of bone tissue degenerates, and the brittleness of bone increases, making it easy to fracture. The prevention of osteoporosis starts at a young age, when the mineral content of the bones reaches its highest level in the 30s, which is medically known as peak bone mass. The higher the peak bone mass, the greater the “bone mineral bank” reserve in the body, and the more delayed and less severe the onset of osteoporosis in old age. Active improvement of diet and lifestyle and adherence to calcium and vitamin D supplementation in old age can prevent or reduce osteoporosis. It is never too late to start treatment at any stage of osteoporosis, but if you are at high risk of osteoporosis, you should go to the hospital as early as possible for early diagnosis and early treatment, which will greatly benefit you.
