WASHINGTON, AFP -- Americans are living longer than ever, with the average life expectancy reaching 78 years in 2005, the Centers for Disease Control and Prevention (CDC) said Wednesday.
華盛頓，法新社 -- 美國疾病控制及預防中心週三指出，美國人二００五年平均壽命為七十八歲，創歷史新高。
But despite the steady upward climb of longevity, the United States was still far behind Japan, Andorra and Italy, where statistics compiled by the World Health Organization (WHO) show that life expectancy exceeds 80 years.
Americans lived for around 69 years in 1955, and 76 years in 1995, the study showed.
The age-adjusted death rate also fell to an all-time low in 2005, bottoming out at fewer than 800 deaths per 100,000 people, the statistics show.
"This report highlights the continued reduction in deaths from the three leading killers in the United States － heart disease, cancer and stroke － which is most likely due to better prevention efforts and medical advances in the treatments of these diseases," said Hsiang-Ching Kung, a statistician at the CDC and one of the report's authors.
The death rate from heart disease fell to 210.3 per 100,000 in 2005 from 217 per 100,000 the previous year.
Deaths from cancer fell from 185.8 per 100,000 to 183.8 per 100,000 during the same period, and stroke deaths fell from 50 to around 47 per 100,000.
The country with the lowest life expectancy in the world is Zimbabwe, where people can expect to live around 36 years, data from WHO shows.
