Jiaquan Xu, MD, from the National Center for Health
Statistics, CDC, Atlanta, Georgia, and colleagues compared 2012 final data with
2011 final data to analyze life expectancy estimates, age-adjusted death rates
by race and ethnicity and sex, top 10 causes of death, and 10 leading causes of
infant mortality.
"Information on mortality patterns is key to
understanding changes in the health and well-being of the U.S.
population," the authors write.
Top Findings
Life expectancy at birth for individuals living in the
United States reached an all-time high of 78.8 years in 2012.
Life expectancy was higher for women (81.2 years) than
for men (76.4 years).
From 2011 to 2013, the age-adjusted death rate for the
United States fell 1.1%, to an historic low of 732.8 per 100,000 standard
population.
The top 10 causes of death in 2012 stayed the same as in
2011: heart disease, cancer, chronic lower respiratory tract diseases, stroke,
unintentional injuries, Alzheimer's disease, diabetes, influenza and pneumonia,
kidney disease, and suicide.
Age-adjusted mortality rates fell significantly from 2011
to 2012 for 8 of the top 10 causes of death. The rate decreased 1.8% for heart
disease, 1.5% for cancer, 2.4% for chronic lower respiratory tract diseases,
2.6% for stroke, 3.6% for Alzheimer's disease, 1.9% for diabetes, 8.3% for
influenza and pneumonia, and 2.2% for kidney disease. The rate for suicide,
however, increased 2.4%. Mortality rates remained the same for unintentional
injury.
The infant mortality rate fell 1.5% from 2011 to 2012 to
a record low of 597.8 infant deaths per 100,000 live births. The top 10 causes
of infant mortality in 2012 stayed the same as in 2011.
The researchers analyzed data obtained from death certificates
filed in 50 states and the District of Columbia that are assembled into the
National Vital Statistics System for 2011 and 2012. They used postcensal
population estimates as of July 1, 2011, and July 1, 2012, that are consistent
with the April 1, 2010, census to calculate mortality rates.
The 2012 mortality rates continued to fall among most
groups identified by sex, race, and Hispanic origin; the changes are fairly
small from year to year, but long-term trends demonstrate visible progress in
lowering mortality. The age-adjusted mortality rate in the United States fell
15.7% — from 869.0 to 732.8 deaths per 100,000 standard population — over 12
years, from 2000 to 2012.
