60 <strong>and</strong> over in all regions. Globally, 60-year-olds have a 55%<br />

chance of dying before <strong>the</strong>ir 70th birthday. Regional variations<br />

in <strong>the</strong> risk of death are smaller at older ages than at younger<br />

ages, ranging from around 40% in <strong>the</strong> developed countries of<br />

Western Europe <strong>to</strong> 60% in most developing regions <strong>and</strong> 70%<br />

in sub-Saharan Africa. His<strong>to</strong>rical data from countries such as<br />

Australia <strong>and</strong> Sweden show that life expectancy at age 60<br />

changed slowly during <strong>the</strong> first six <strong>to</strong> seven decades of <strong>the</strong><br />

20th century, but started <strong>to</strong> increase substantially since<br />

around 1970. Life expectancy at age 60 has now <strong>reach</strong>ed 25<br />

years in Japan. In Eastern Europe from 1990 onwards,<br />

Hungary, <strong>and</strong> Pol<strong>and</strong> started <strong>to</strong> experience similar<br />

improvements in mortality for older people, but Russia has<br />

not, <strong>and</strong> is actually experiencing a worsening trend.<br />

Regional variations in causes of death<br />

The 10 leading causes of mortality differ greatly between<br />

regions (Table 6). IHD <strong>and</strong> cerebrovascular disease are<br />

among <strong>the</strong> <strong>to</strong>p four causes of death in all low- <strong>and</strong> middleincome<br />

regions except sub-Saharan Africa, where <strong>the</strong>y are<br />

8th <strong>and</strong> 7th, respectively. Cerebrovascular disease is <strong>the</strong><br />

leading cause of death in East Asia <strong>and</strong> <strong>the</strong> Pacific, unlike in<br />

most o<strong>the</strong>r regions, where IHD causes more deaths than<br />

cerebrovascular disease. In sub-Saharan Africa, 6 of <strong>the</strong> <strong>to</strong>p<br />

10 causes are communicable diseases, with HIV/AIDS being<br />

<strong>the</strong> leading cause of death, followed by malaria <strong>and</strong> lower<br />

respira<strong>to</strong>ry infections.<br />

South Asia (mainly India) <strong>and</strong> Latin America <strong>and</strong> <strong>the</strong><br />

Caribbean are <strong>the</strong> only two o<strong>the</strong>r low- <strong>and</strong> middle-income<br />

regions where HIV/AIDS is one of <strong>the</strong> <strong>to</strong>p 10 causes of death.<br />

Lower respira<strong>to</strong>ry infections, primarily pneumonia, are <strong>the</strong><br />

third leading cause of death, especially among children<br />

under five, who account for 60% of <strong>the</strong>se deaths. Chronic<br />

obstructive pulmonary disease kills more people (1.4 million)<br />

in <strong>the</strong> East Asia <strong>and</strong> Pacific region, primarily China, than<br />

anywhere else in <strong>the</strong> world, with 50% of global mortality<br />

from <strong>the</strong> disease occurring <strong>the</strong>re.<br />

Europe <strong>and</strong> Central Asia differs from all o<strong>the</strong>r low- <strong>and</strong><br />

middle-income regions in <strong>the</strong> size of <strong>the</strong> CVD epidemic (with<br />

almost 60% of deaths due <strong>to</strong> CVD), followed by trachea,<br />

bronchus, <strong>and</strong> lung cancers in third place. Self-inflicted injuries<br />

(suicide) are <strong>the</strong> fifth leading cause of death in this region.<br />

South Asia is <strong>the</strong> only o<strong>the</strong>r region where suicide is in <strong>the</strong> <strong>to</strong>p<br />

10 causes of death. Latin America <strong>and</strong> <strong>the</strong> Caribbean is<br />

distinguished as <strong>the</strong> only region where violence falls in <strong>the</strong> <strong>to</strong>p<br />

10 causes of death, responsible for 1 in 25 deaths. In all low<strong>and</strong><br />

middle-income regions apart from Europe <strong>and</strong> Central Asia,<br />

road traffic accidents are included among <strong>the</strong> <strong>to</strong>p 10 causes of<br />

death, <strong>reach</strong>ing fifth position in <strong>the</strong> Middle East <strong>and</strong> North<br />

Africa, where <strong>the</strong>y are responsible for 1 in 20 deaths.<br />
