In early 1990s, Jamison, Mosley and others concluded that a profound demographic and consequent epidemiological transition is taking place in developing countries. According to this classical model, by the year 2015, infectious diseases will account for only about 20% of deaths in developing countries as chronic diseases become more pronounced. These impending demographic and epidemiological transitions were to dominate the health sector reform agenda in developing countries. Following an analysis of fertility, mortality and other demographic and epidemiological data from South Asian and other developing countries, the paper argues that the classical model is in need of re-evaluation. A number of new 'challenges' have complicated the classical interplay of demographic and epidemiological factors. These new challenges include continuing population growth in some countries, rapid unplanned urbanization, the HIV/AIDS pandemic in Sub-Saharan Africa (and its impending threat in South Asia), and globalization and increasing marginalisation of developing countries. While the traditional lack of investment in human development makes the developing countries more vulnerable to the vicissitudes of globalization, increasing economic weakness of their governments forces them to retreat further from the social sector. Pockets of poverty and deprivation, therefore, persist giving rise to three simultaneous burdens for South Asia and much of the rest of the developing world: continuing communicable diseases, increasing burden of chronic diseases, and increasing demand for both primary and tertiary levels of health care services. While these complex factors, on the one hand, underscore the need for health sector reform, on the other, they make the task much more difficult and challenging. The paper emphasizes the need to revisit the classical model of demographic and epidemiological transition. It is argued that the health sector in developing countries must be aware of and effectively address these 'new challenges'. Although it has included data from many developing countries, the focus is primarily on South Asia.
20世纪90年代初,贾米森、莫斯利等人得出结论,发展中国家正在发生深刻的人口结构变化以及随之而来的流行病学转变。根据这一经典模型,到2015年,随着慢性病变得更加突出,传染病在发展中国家的死亡原因中所占比例将仅约为20%。这些即将到来的人口结构和流行病学转变将主导发展中国家卫生部门的改革议程。在分析了来自南亚和其他发展中国家的生育率、死亡率以及其他人口结构和流行病学数据之后,本文认为这一经典模型需要重新评估。一些新的“挑战”使人口结构和流行病学因素之间的经典相互作用变得复杂。这些新挑战包括一些国家持续的人口增长、快速的无规划城市化、撒哈拉以南非洲的艾滋病毒/艾滋病大流行(以及其在南亚迫在眉睫的威胁),以及全球化和发展中国家日益边缘化。虽然传统上对人类发展缺乏投资使发展中国家更容易受到全球化变迁的影响,但各国政府日益加剧的经济疲软迫使它们进一步从社会部门撤出。因此,贫困和匮乏地区依然存在,给南亚和其他许多发展中世界带来了三个同时存在的负担:持续的传染病、慢性病负担加重,以及对初级和三级卫生保健服务的需求不断增加。一方面,这些复杂因素凸显了卫生部门改革的必要性,另一方面,它们也使这项任务更加困难和具有挑战性。本文强调有必要重新审视人口结构和流行病学转变的经典模型。有人认为,发展中国家的卫生部门必须意识到并有效应对这些“新挑战”。虽然本文纳入了许多发展中国家的数据,但其重点主要是南亚。
