Media reporter friends and guests, welcome to participate in the media communication meeting of the National Health and Health Commission. Today the communication meeting is mainly to introduce to you the main conclusions of the osteoporosis epidemiological survey in China and the status of the "healthy bones" special action. In April last year, the former National Health and Family Planning Commission and the five departments jointly issued the “Health Action Plan for the Whole People (2017-2025)”, which proposed the in-depth implementation of “three reductions and three health” (oil reduction, salt reduction, sugar reduction, health Oral, healthy weight, healthy bones), and four special action plans including regular exercise, tobacco control and mental health, and a series of publicity activities were launched in our media. Two press conferences were held to introduce the "three "Three reductions" in "Three reductions" and healthy oral cavity information in "Three reductions". At that time, media friends also made very good publicity reports, and the masses gained relevant health knowledge. Tomorrow is World Osteoporosis Day, and today invites Zhang Yong, Deputy Director of the CDC of the National Health and Health Committee, Chairman of the Chinese Medical Association Osteoporosis and Bone Mineral Disease Branch, Xia Weibo, Director of Endocrinology, Peking Union Medical College Hospital, China Centers for Disease Control and Prevention Li Zhixin, Secretary of the Center for Chronic Diseases, and researcher Wang Linhong, former director of the Center for Chronic Diseases, China Centers for Disease Control and Prevention. Today four guests will introduce the situation at the communication meeting. The agenda of this afternoon's meeting is to first invite Deputy Director Zhang Yong to introduce the main ratcheting of the osteoporosis survey in China and the special action of "Healthy Bone", and then Director Zhang and the three will jointly answer questions of everyone's interest.

In accordance with the agenda of today's meeting, I will first ask Director Zhang to introduce the relevant situation.

Zhang Yong:
  good afternoon everyone! Thank you very much and welcome all journalists and media friends to participate in this media communication meeting. Let me briefly introduce the situation of osteoporosis epidemiological investigation and "healthy bone" special action in China.
I should say that what is introduced today may be a disease that is not of high social concern: osteoporosis. But osteoporosis is the most common skeletal disease that affects residents' health. There are usually no obvious clinical manifestations in the early stages of the disease. If it is not taken seriously, as the disease progresses, it will lead to pain, spinal deformity, fractures and other conditions. Medical and care costs. The National Health and Health Committee attaches great importance to the prevention and control of osteoporosis. The host also just introduced that our committee regards the "Healthy Bone" action as an important part of the "three reductions and three health" special action for the nation's healthy lifestyle. A working requirement put forward in the "Healthy China 2030" Planning Outline. In order to grasp the epidemic situation of osteoporosis and its risk factors in China, scientifically formulate osteoporosis prevention and control policies. Starting this year, the state will select 11 provinces across the country with the support of major central public payment public health projects44 More than 20,000 people from counties (districts) conducted the first epidemiological survey of osteoporosis in Chinese residents. The field investigation and data analysis have been completed. Let me briefly introduce some of the main conclusions of this survey.

1.Osteoporosis has become an important health problem for people over 50 years of age in China, and the problem of osteoporosis in middle-aged and elderly women is particularly serious.
Based on the Chinese peak bone mass data obtained in this survey, according to the international gold standard for diagnosis of osteoporosis (ie, when the bone density reduction reaches or exceeds 2.5 standard deviations of the peak bone average of healthy adults of the same sex and race (Diagnosable osteoporosis). The survey shows that the prevalence of osteoporosis in the 40-49-year-old population in China is 3.2%, of which 2.2% is male, 4.3% is female, and female is twice as much as male. It is 3.5% in urban areas and 3.1% in rural areas. The prevalence of osteoporosis in people over 50 years of age is 19.2%, which has increased significantly. Among them, 6.0% are males and 32.1% are females, which is five times that of males. 16.2% in urban areas and 20.7% in rural areas. The prevalence of osteoporosis in people over 65 years of age is 32.0%, of which 10.7% are male, 51.6% are female, 25.6% are urban area, and 35.3% are rural area.

Through literature search and international comparison, it is found that the prevalence of osteoporosis in men in China (6.0% over 50 years old) is not much different from that in other countries (the prevalence of osteoporosis in men over 50 years old in the United States is 5.1%, and that in Canada is 6.6%, South Korea: 7.3%), the prevalence level of women (32.1% over 50 years old) is significantly higher than in European and American countries, and is similar to Asian countries such as Japan and South Korea (the prevalence of osteoporosis in women over 50 years old in the United States is 16.5 %, Canada 15.8%, South Korea 38%).

2. The population with low bone mass in China is huge and is at high risk for osteoporosis.
The degree of reduction of iliac bone density is between 1 and 2.5 standard deviations of the peak bone average of healthy adults of the same sex and same race, which is called low bone mass population. The survey shows that the low bone mass rate in China's 40-49-year-old population reaches 32.9%, of which 34.4% are male, 31.4% are female, 31.2% are urban area, and 33.9% are rural area. The low bone mass rate for people over the age of 50 is 46.4%, including 46.9% for men, 45.9% for women, 45.4% in urban areas, and 46.9% in rural areas. Among those without osteoporosis, the low bone mass rate in the 40-49 age group reached 34.0%, of which 35.2% was male and 32.8% was female. 49.9% and 67.6% of women.  

3. Residents' awareness of osteoporosis is generally inadequate, and the detection rate of bone density needs to be improved.
The survey shows that the awareness rate of osteoporosis-related knowledge in people over 20 years old is only 11.7%, of which 10.5% are male, 13.0% are female, 17.8% are urban area, and 8.1% are rural area. Among osteoporosis patients, the proportion of patients who know their own disease is also low. The prevalence rate of osteoporosis patients aged 40-49 years old is 0.9%, and the prevalence rate of patients over 50 years old is only 7.0% .

The proportion of people over the age of 20 who have been tested for bone mineral density is only 2.8%, of which 2.5% are male, 3.2% are female, 5.0% are urban area, and 1.5% are rural area. Among the population over 50 years old, the proportion of people who received bone density test was 3.7%, of which 3.2% were male, 4.3% were female, 7.4% were urban, and 1.9% were rural.

The occurrence of osteoporosis is closely related to the accumulation of basal bone mass and bone loss after aging. The mineral content in human bones reaches the highest peak bone mass around the age of 30. The higher the level of bone mass accumulation, the later the osteoporosis occurs in middle-aged and elderly people, and the symptoms and severity will be lighter. Unhealthy lifestyle and increasing age are the main reasons for the high incidence of osteoporosis. Unbalanced diet, sedentary lifestyles, too little sunshine, smoking, drinking, and drug use not only affect basic bone accumulation levels, but also lead to bone loss in middle-aged and elderly people, increasing the risk of osteoporosis. After 50 years of age, the low bone mass rate and the prevalence of osteoporosis begin to increase, mainly related to the decline in sex hormone levels caused by aging, and the decline in estrogen levels in women is particularly obvious, so the prevalence of women is significantly higher than that of men. . With the continuous acceleration of the process of urbanization and population aging in China and the widespread prevalence of unhealthy lifestyles, the prevention and control of osteoporosis in China will become increasingly severe.
  On the other hand, the low level of osteoporosis awareness and bone mineral density in the general public is an important reason leading to the large population of low bone mass in China. Low bone mass status and pre-osteoporosis usually have no obvious clinical manifestations. Due to the lack of public awareness of the importance of osteoporosis prevention, coupled with inadequate osteoporosis prevention and treatment capabilities in primary health care institutions, bone density testing in China The rate is low, and most residents did not take timely prevention and control measures at the early stage of bone loss. However, they found themselves ill after suffering pain, spinal deformity, and fractures, which delayed the favorable time for the prevention and treatment of osteoporosis.
