A new, first-of-its-kind infographic published in the Centers for Disease Control and Prevention’s Preventing Chronic Disease journal maps the most ‘distinctive’ causes of deaths across all states in the US.
The map presents 2001-10 data on causes of death within individual states that were statistically more significant than the national averages, drawn from the Centers for Disease Control and Prevention’s (CDC) own “Underlying Cause of Death” file, which is accessible through the WONDER (Wide-ranging Online Data for Epidemiologic Research) website.
The largest number of deaths in the map from a single condition were the 37,292 deaths from atherosclerotic cardiovascular disease in Michigan. The fewest were 11 deaths from “acute and rapidly progressive nephritic and nephrotic syndrome” in Montana.
The numbers of death from discrete illnesses varied across states. For example, 15,000 HIV-related deaths were recorded in Florida during the study period, 679 deaths from tuberculosis in Texas, and 22 people died from syphilis in Louisiana.
The most distinctive causes of death in New York were from gonorrhea and chlamydia, and the state also had the highest number of deaths from infection of female reproductive organs – mostly as a result of untreated sexually transmitted diseases.
According to the researchers behind the map, some of the findings make “intuitive sense,” such as the high numbers of death from influenza in northern states, or pneumoconiosis (black lung disease) in states where coal is mined. However, some of the other findings are less easily explained, such as the deaths from septicemia in New Jersey.
The map only presents one distinctive cause of death for each state, all of which were significantly higher than the national rate. However, many other causes of death that were also significantly higher than national rates were not mapped.
Another limitation of the map is that it has a predisposition toward exhibiting rare causes of death. For instance, in 22 of the states, the total number of deaths mapped was under 100.
“These limitations are characteristic of maps generally and are why these maps are best regarded as snapshots and not comprehensive statistical summaries,” explain the researchers, Francis P. Boscoe, of the New York State Cancer Registry, and Eva Pradhan, of the New York State Department of Health.
Boscoe and Pradhan say that the map has been “a robust conversation starter” – generating hypotheses that they consider would not have occurred had the data been formatted in “an equivalent tabular representation.” They add:
“Although chronic disease prevention efforts should continue to emphasize the most common conditions, an outlier map such as this one should also be of interest to public health professionals, particularly insofar as it highlights nonstandard cause-of-death certification practices within and between states that can potentially be addressed through education and training.”
In 2014, Medical News Today reported on a study investigating state-by-state variations in firearms-related fatalities. Published in BMJ Open, the study found that state with the lowest recorded rate of gun-related deaths was Hawaii, with 3.02 gun deaths per 100,000 citizens. The highest number of firearm-related fatalities occurred within the District of Columbia, with 21.71 firearm deaths per 100,000 people.
