The Centers for Disease Control and Prevention estimates that 29.1 million Americans today have diabetes. While diabetes is the seventh leading cause of death in the U.S., most cases of type 2 diabetes are preventable. Diabetes can be prevented by healthy eating, weight management, and an active lifestyle — factors which vary heavily by geography. An estimated 8.2% of adults in the Washington-Arlington-Alexandria metro area have diabetes, less than the national share of 9.3%.
According to the CDC, more than one in three Americans is prediabetic. A person with prediabetes has blood sugar levels higher than normal, and is 15% to 30% more likely to develop diabetes within five years. Prediabetes is mostly caused by lifestyle factors such as diet and exercise, as well as risk factors such as age and family history. In Washington, some 18.8% of adults do not exercise outside of work, lower than the national share of 23.0% inactive Americans.
In inactive lifestyle can affect the likelihood of excess body fat, and a low share of inactive residents often results in a low obesity rate. In Washington, 24.3% of residents are obese, lower than the national rate of 27.0%.
Residents of Washington are also less likely to engage in other unhealthy behaviors. For example, the city’s 13.1% smoking rate and 17.5% excessive drinking rate are both lower than than the corresponding national rates of 17.0% and 18.0%.
Diabetes is often more prevalent in low-income areas where residents tend to have lower education levels. Individuals living in impoverished neighborhoods are less likely to have adequate access to healthy food, opportunities for exercise, or preventative health care. According to one study, residents of poor neighborhoods are up to twice as likely to have diabetes than those in wealthy neighborhoods.
In the Washington metro area, the typical household earns $93,294 annually, roughly $37,500 more than the national median household income of $55,775. An estimated 49.3% of adults in Washington have a bachelor’s degree, a larger share than the national college attainment rate of 30.6%.
Diabetes increases the risk of blindness, kidney failure, heart disease, and stroke. Ultimately, the risk of death is 50% higher for adults with diabetes than those without. Diabetes causes 76,600 deaths in the U.S. annually, or roughly 24 per 100,000 Americans. Overall, an estimated 474 in 100,000 Americans die prematurely before the age of 75 each year. In the Washington metro area, there are 277 deaths per 100,000 metro area residents, more than the national mortality rate.
