2000—2050年,全球60岁以上的人口将增长3倍,从6亿人增加到20亿。其中大部分增长发生在发展中国家,这些国家中的老年人口将从2000年的4亿人增加到2050年的17亿。这一人口变化对公共卫生具有多重影响。身体健康是老年人保持独立生活能力的基本要素,它在家庭和社区生活中也起到重要作用。促进健康长寿和疾病预防活动可以预防或延迟传染病和慢性病发作,诸如心脏病、卒中和癌症等。
Between 2000 and 2050, the global population over the age of 60 will triple from 600 million to 2 billion. Much of this growth will take place in developing countries, where the elderly population will increase from 400 million in 2000 to 1.7 billion in 2050. This demographic change has multiple implications for public health. Physical well-being is an essential element of the elderly’s ability to maintain an independent life, and it also plays an important role in family and community life. Promote health, longevity and disease prevention activities can prevent or delay the spread of infectious diseases and the onset of chronic diseases such as heart disease, stroke and cancer.
