The study, published in the CDC's Morbidity and Mortality Weekly Report, found 20 percent to 40 percent of deaths from each cause could actually be prevented. Southeastern states had the highest number of preventable deaths for each of the five causes.
For the report, the CDC reviewed state to state data on death records between 2008 and 2010 of people younger than age 80. The authors then calculated premature death rates that could have been prevented if all states had the same number of deaths as states with the lowest rates for each cause. According to the CDC it is possible to prevent:
- 34 percent of premature deaths from heart diseases, prolonging about 92,000 lives- 21 percent of premature cancer deaths, prolonging about 84,500 lives
- 39 percent of premature deaths from chronic lower respiratory diseases, prolonging about 29,000 lives
- 33 percent of premature stroke deaths, prolonging about 17,000 lives- 39 percent of premature deaths from unintentional injuries, prolonging about 37,000 lives
However, the authors of the report say the number of preventable deaths from each cause cannot be added together to produce nationwide numbers. This is due to the fact that people who recover from a serious disease, such as cancer, may die from another top killer such as stroke or unintentional injury. And chronic diseasecomorbidity is common and raises the risk for early death.
The report acknowledges that premature deaths from the five leading causes often are a result of unfavorable lifestyle and environmental factors. These include alcohol and tobacco use, poor diet, obesity, sun exposure, pollution and chemical exposure. The CDC's report links unintentional injury to factors such as lack of seat belt and bike helmet use, unsafe consumer products, drug misuse or abuse and unsafe public and private environments.
Many of these risk factors are associated with socioeconomic disparities, which play a role in the health of both public and private environments. The CDC report may help states adopt policies that address risk factors associated with early death from these top five killers.
