Cities can learn lessons about diabetes from rural areas

Posted June 19, 2013, 11:00 am

City dwellers often think of rural America as a throwback to past “good old days.” But when it comes to obesity and diabetes, people living outside urban areas offer a frightening glimpse of the future.

Last week I had the opportunity to moderate a panel discussion on rural health, sponsored by the Association for Health Care Journalists (AHJC) in Birmingham, Alabama. The discussion highlighted troubling statistics on diabetes, raised some knotty issues, and explored creative solutions.

More than 8% of Americans now have diabetes, a percentage that’s expected to grow along with our waistlines. Diabetes is already the nation’s leading cause of kidney failure, non-traumatic limb amputation, and new cases of blindness. It’s the seventh leading cause of death, and would rank higher if deaths from heart disease accelerated by underlying diabetes were included. What would a much higher diabetes rate look like?

The answer lies just outside nearly every metropolitan area in the diabetes belt that extends across the Southeastern United States. Surrounding Birmingham, Alabama, for example, are several rural counties where about 20% of people have diabetes.

“Diabetes is definitely not distributed evenly across the country,” said Dr. Andrea L. Cherrington, associate professor at the University of Alabama at Birmingham (UAB), pointing to a CDC county-level map of diabetes prevalence. It’s not just rural versus urban, Dr. Cherrington added. Urban areas in the diabetes belt have higher rates of diabetes than urban areas outside of the diabetes belt.

Dr. Cherrington next pointed to a map showing the U.S. counties with the highest levels of obesity. The map looks nearly identical to the diabetes map. The answer to obesity is better nutrition and more exercise. What makes it more difficult to manage weight in rural communities?

The answer to that question will look familiar to anyone who’s been to the less-advantaged parts of any U.S. town or city: barriers to health. These include:

Limited access to health care, especially to specialists such as endocrinologistsMinimal exposure to diabetes educationLimited access to safe sidewalks, exercise facilities, and grocery stores with affordable produce.High rates of poverty.

Such barriers get in the way of exercising, eating a healthy diet, and other healthy lifestyle choices. They also lead to obesity and its many consequences.

“It’s not easy living with diabetes,” Dr. Cherrington said, noting that disease management requires mastering a complex schedule of medications, exercise, self-care, and doctor appointments. “If you overlay this regimen on these barriers to health, it becomes really challenging. If you don’t have resources, it is easy to see how disparity can exist.”

Battling the obesity epidemic has been the life work of panelist Bonnie A. Spear, professor of pediatrics at the University of Alabama, Birmingham, and a nationally recognized expert in child and adolescent obesity.

Spear noted that overweight and obese children and teens tend to become obese adults. Obese children who become obese adults are at extremely high risk of developing diabetes and other chronic conditions.

Too often, Spears argued, we fuss over details such as whether schools should offer chocolate milk rather than whether schools should be allowed to make money from on-campus vending machines, which often sell sugary soft drinks and snacks. Too often, she said, we worry about the cost of providing breakfast and lunch to too many kids when missed breakfast and poor nutrition are linked to lower test scores and difficulty concentrating. And when we worry that U.S. kids are falling behind in academics, physical education classes are the first thing to go—even though fit kids do better at academic subjects than unfit kids. Creating healthy school environments is crucial for preventing obesity and diabetes in the next generation of adults.

When it comes to adults who have diabetes today, one key problem is the lack of primary care physicians. While cities have too few of them, noted Dr. William Curry, associate dean for primary care and rural medicine at the University of Alabama, Birmingham,  the problem often is worse in rural areas, particularly for those who lack transportation.

Part of the answer may be community health workers, Dr. Cherrington suggested. Her work shows that community health workers—lay people trained to provide diabetes education and outreach—can have a major impact on the wellbeing of people with diabetes living in rural areas.

That work has turned her attention to cities, as she now leads Birmingham’s Cities for Life program. Led by the American Academy of Family Physicians, the program borrows from the rural community health worker concept by having doctors refer people with diabetes to “patient navigators” who help them find local resources such as nearby exercise classes or mobile farmers’ markets.

In addition to the clinical component of the program, its community component makes use of a community action team made up of more than 80 organizations drawn from local primary care, health, civic, business, and charitable organizations. A major part of this effort is the mydiabetesconnect.com website, which shows people where to find resources in their own neighborhoods.

Will it work? The program is just a year old, but Dr. Cherrington believes Birmingham eventually will become a model for diabetes control—in both urban and rural areas.
