These are the 10 unhealthiest states in the US

The unhealthiest states in the country all lie in the southeast US.

For the 28th year in a row, the United Health Foundation has ranked America's states based on factors including obesity, air pollution, and poverty. Massachusetts made the top of the list as America's healthiest state, while Mississippi was declared the unhealthiest.

Here's a map, with the healthiest states in light blue and the least healthy in dark blue.

Looking at data from the Centers for Disease Control and Prevention, the American Medical Association, and the Census bureau, the rankings took into account everything from obesity and smoking to community and environmental factors, such as child poverty and air pollution, to public policies like immunizations, and health outcomes like cancer deaths and diabetes.

Massachusetts ranked the healthiest state for the first time in the ranking's 28-year history. "Massachusetts' strengths include the lowest percentage of uninsured at 2.7% of the population, a low prevalence of obesity and a high number of mental health providers," the report said.

It was followed by Hawaii, Vermont, Utah, and Connecticut to round out the top five healthiest states.

At the same time, the UHF noted some troubling trends: premature death (that is, deaths that occur before an older age) rate and the drug death rate have both been increasing.

Here's the list of the 10 unhealthiest states, according to the report.
