Asian countries have wide variations of population, wealth, technology and health care, causing attitudes towards health and illness to differ. Japan, for example, has the third highest life expectancy (82 years old), while Afghanistan has the 11th worst (44 years old). Key issues in Asian health include childbirth and maternal health, HIV and AIDS, mental health, and aging and the elderly. These problems are influenced by the sociological factors of religion or belief systems, attempts to reconcile traditional medicinal practices with modern professionalism, and the economic status of the inhabitants of Asia.
