The Diabetes Belt Is Real — And It Overlaps With Almost Everything Else

When you put our state health rankings side by side, one pattern jumps out immediately: the same handful of states keep showing up at the top.

Take West Virginia. According to CDC data, it ranks #1 for diabetes (18.4% of adults), #1 for adult smoking (20.8%), and #1 for obesity (41.4%). Three separate maps, three different surveys, one state at the top of all of them.

The cluster is geographic

This is not random. The states with the highest diabetes rates form a clear band across Appalachia and the Deep South — what researchers have long called the "diabetes belt." Our 2024 data shows the top five as West Virginia, Kentucky, Louisiana, Arkansas, and Mississippi. Four of those five also sit in the top six for obesity.

The reason these conditions travel together is that they share risk factors. Diabetes tracks closely with obesity and physical inactivity, and our most inactive adults map tells the same regional story: Mississippi (#1), West Virginia (#2), and Arkansas (#3) lead the country in adults who get no leisure-time exercise.

The other end of the list

The mirror image is just as consistent. Colorado ranks #50 for diabetes (the lowest rate, 8.4%) and #50 for obesity (25.0%). Utah is #50 for smoking (5.7%) and near the bottom for diabetes and inactivity too. The Mountain West consistently posts the healthiest numbers across our health maps.

Why it matters

None of this is a value judgment about the people who live in these states — these are population-level survey results shaped by income, age, access to care, and decades of economic history. But seeing the overlap laid out across multiple independent CDC surveys is a useful reminder that "health" is rarely about a single number.
