原发性骨质疏松症是以骨量减少、骨的微观结构退化为特征的,致使骨的脆性增加以及易于发生骨折的一种全身性骨骼疾病。作为一种退行性疾病,它伴随着人体机能的老化而产生。目前,全球已经进入人口老龄化阶段。我国是世界上老年人口最多的国家,目前的老龄人口约1.3亿,并以每年3.2％的速度持续增长,将在本世纪中叶进入老龄高峰期,预计届时60岁以上的老人将达到4.1亿,占总人口的四分之一。老龄人口增长的主要原因之一是人类平均寿命的延长,其中尤为明显的是妇女寿命的延长。二十世纪,妇女平均寿命近80岁,以绝经年龄平均在50岁计,则妇女的一生中有1/3时间在绝经后度过。因此,与年龄老化、妇女绝经密切相关的原发性骨质疏松症目前已经成为常见病、多发病。据统计,目前全世界大约
Primary osteoporosis is a systemic skeletal disease characterized by reduced bone mass, degradation of the microstructure of the bone, increased bone fragility and increased susceptibility to fracture. As a degenerative disease, it is accompanied by aging of the human body. At present, the world has entered the stage of population aging. As the country with the largest population of the elderly in the world, China currently has an estimated population of about 130 million and an annual growth rate of 3.2%. It will enter the peak of the aging age by the middle of this century. By then, the number of the elderly over the age of 60 will reach 410 million. One-fourth of the total population. One of the main causes of the aging population is an extension of the average life expectancy of human beings, with the notable increase being the longer life expectancy of women. In the twentieth century, the average life expectancy of women was nearly 80 years and the average age of menopause was 50 years old, then one third of the woman’s lifetime spent in menopause. Therefore, the primary osteoporosis, which is closely related to age-related aging and women’s menopause, has now become a common disease and frequently-occurring disease. According to statistics, around the world now
