Life expectancy in U.S. hits record high
According to a new report issued by the Centers for Disease Control (CDC), life expectancy in the U.S. is at an all-time high at 78.8 years. The CDC attributes the increase in longevity to a reduction in cancer, stroke, and heart disease.
To conduct their research, scientists compared final mortality data on deaths and death rates from 2012 with that of 2011. They also investigated age-adjusted death rates by ethnicity and sex, the 10 leading causes of death and the 10 leading causes of infant death.
The report showed that in 2012, the life expectancy for females stood at 81.2 years, while the life expectancy for men was 76.4 years. This difference of 4.8 years is the same as reported in 2011, showing that women are still living longer than men.
Not much has changed as far as the leading causes of death: The list includes heart disease, cancer, chronic lower respiratory diseases, stroke, unintentional injuries, Alzheimer's disease, diabetes, influenza and pneumonia, kidney disease and suicide. However, the researchers found that for eight of these leading causes of death, age-adjusted death rates had significantly declined in 2011-2012.
The authors also found a decline in infant mortality rates, showing a significant drop in deaths from sudden infant death syndrome (SIDS).
