Death Rates Drop for 5 Top Causes of Death

Oct. 10, 2012 -- Death rates dropped significantly last year for five out of the 15 leading causes of death in the U.S., according to a new CDC report.

Researchers say a major decline in three of the top five causes of death, including heart disease, cancer, and stroke, contributed to a slight decline in the rate of overall deaths in 2011.

The report also shows the death rate, which accounts for changes in the age distribution of the country, reached a record low in 2011.

But the average American’s life expectancy remained the same at 78.7 years from 2010 to 2011.

Death Rates Drop for Top Causes

Researchers say the 3% decline in heart disease deaths and 2.4% drop in cancer-related deaths were especially significant because deaths from these two diseases accounted for 47% of all deaths in the U.S. in 2011.

The report shows the ranking of the leading 15 causes of death stayed relatively the same from 2010 to 2011, although kidney-related causes of death (ranked No. 8 in 2010) and influenza/pneumonia (ranked No. 9 in 2010) exchanged ranks, as indicated below.

Death rates increased for six other major causes of death.

Top 15 Causes of Death (% change from 2010 to 2011):

  1. Heart disease (-3%)
  2. Cancer (-2.4%)
  3. Chronic lower respiratory diseases, including chronic obstructive pulmonary disease, emphysema, and bronchitis (+1.2%)
  4. Stroke (-3.1%)
  5. Accidents or unintentional injuries (unchanged)
  6. Alzheimer’s disease (-2%)
  7. Diabetes (+3.4%)
  8. Influenza and pneumonia (+4%)
  9. Kidney-related diseases, including nephritis, nephrotic syndrome, and nephrosis (-12.4%)
  10. Suicide (-0.8%)
  11. Septicemia, an infection of the blood that affects the whole body (-0.9%)
  12. Chronic liver disease and cirrhosis (+3.2%)
  13. High blood pressure or hypertension (unchanged)
  14. Parkinson’s disease (+2.9%)
  15. Pneumonitis or inflammation of the lungs (+3.9%)

Researchers say the 12% drop in deaths due to kidney-related disorders should be interpreted with caution because changes in coding and classification contributed to this decrease. 

Although HIV was not among the 15 leading causes of death in 2011, researchers say it remains a public health concern, especially among those 15-64 years old. The death rate for HIV decreased by 7.7% from 2010 to 2011.
