Globally, 60-year-olds have a 55%chance of dying before <strong>the</strong>ir 70th birthday. Regional variationsin <strong>the</strong> risk of death are smaller at older ages than at youngerages, ranging from around 40% in <strong>the</strong> developed countries ofWestern Europe <strong>to</strong> 60% in most developing regions <strong>and</strong> 70%in sub-Saharan Africa. His<strong>to</strong>rical data from countries such asAustralia <strong>and</strong> Sweden show that life expectancy at age 60changed slowly during <strong>the</strong> first six <strong>to</strong> seven decades of <strong>the</strong>20th century, but started <strong>to</strong> increase substantially sincearound 1970. Life expectancy at age 60 has now <strong>reach</strong>ed 25years in Japan. In Eastern Europe from 1990 onwards,Hungary, <strong>and</strong> Pol<strong>and</strong> started <strong>to</strong> experience similarimprovements in mortality for older people, but Russia hasnot, <strong>and</strong> is actually experiencing a worsening trend.Regional variations in causes of deathThe 10 leading causes of mortality differ greatly betweenregions (Table 6). IHD <strong>and</strong> cerebrovascular disease areamong <strong>the</strong> <strong>to</strong>p four causes of death in all low- <strong>and</strong> middleincomeregions except sub-Saharan Africa, where <strong>the</strong>y are8th <strong>and</strong> 7th, respectively. Cerebrovascular disease is <strong>the</strong>leading cause of death in East Asia <strong>and</strong> <strong>the</strong> Pacific, unlike inmost o<strong>the</strong>r regions, where IHD causes more deaths thancerebrovascular disease. In sub-Saharan Africa, 6 of <strong>the</strong> <strong>to</strong>p10 causes are communicable diseases, with HIV/AIDS being<strong>the</strong> leading cause of death, followed by malaria <strong>and</strong> lowerrespira<strong>to</strong>ry infections.South Asia (mainly India) <strong>and</strong> Latin America <strong>and</strong> <strong>the</strong>Caribbean are <strong>the</strong> only two o<strong>the</strong>r low- <strong>and</strong> middle-incomeregions where HIV/AIDS is one of <strong>the</strong> <strong>to</strong>p 10 causes of death.Lower respira<strong>to</strong>ry infections, primarily pneumonia, are <strong>the</strong>third leading cause of death, especially among childrenunder five, who account for 60% of <strong>the</strong>se deaths. Chronicobstructive pulmonary disease kills more people (1.4 million)in <strong>the</strong> East Asia <strong>and</strong> Pacific region, primarily China, thananywhere else in <strong>the</strong> world, with 50% of global mortalityfrom <strong>the</strong> disease occurring <strong>the</strong>re.Europe <strong>and</strong> Central Asia differs from all o<strong>the</strong>r low- <strong>and</strong>middle-income regions in <strong>the</strong> size of <strong>the</strong> CVD epidemic (withalmost 60% of deaths due <strong>to</strong> CVD), followed by trachea,bronchus, <strong>and</strong> lung cancers in third place. Self-inflicted injuries(suicide) are <strong>the</strong> fifth leading cause of death in this region.South Asia is <strong>the</strong> only o<strong>the</strong>r region where suicide is in <strong>the</strong> <strong>to</strong>p10 causes of death. Latin America <strong>and</strong> <strong>the</strong> Caribbean isdistinguished as <strong>the</strong> only region where violence falls in <strong>the</strong> <strong>to</strong>p10 causes of death, responsible for 1 in 25 deaths. In all low<strong>and</strong>middle-income regions apart from Europe <strong>and</strong> Central Asia,road traffic accidents are included among <strong>the</strong> <strong>to</strong>p 10 causes ofdeath, <strong>reach</strong>ing fifth position in <strong>the</strong> Middle East <strong>and</strong> NorthAfrica, where <strong>the</strong>y are responsible for 1 in 20 deaths.Global burden of disease in 2001The 20 leading causes of burden of disease for both sexes<strong>to</strong>ge<strong>the</strong>r are shown in Table 7.

This once again illustrates <strong>the</strong>importance of taking nonfatal conditions in<strong>to</strong> account, as wellas deaths, when assessing <strong>the</strong> causes of loss of <strong>health</strong> inpopulations.In 2001, <strong>the</strong> leading causes of <strong>the</strong> burden of disease inlow- <strong>and</strong> middle-income countries were broadly similar <strong>to</strong>those for <strong>the</strong> world as a whole (Table 8), <strong>and</strong> included sixGroup I causes among <strong>the</strong> <strong>to</strong>p 10, but <strong>the</strong> leading causes inhigh-income countries consisted entirely of Group IIconditions, including three (unipolar depressive disorders,adult-onset hearing loss, <strong>and</strong> alcohol use disorders) for whichdirect mortality is low.Age <strong>and</strong> sex differences in <strong>the</strong> burden ofdiseaseChildren younger than 15 accounted for 36% of <strong>the</strong> world’s<strong>to</strong>tal burden of disease <strong>and</strong> injury in 2001 <strong>and</strong> adults age 15<strong>to</strong> 59 accounted for almost 50%.
