Diabetes: Rural populations suffer higher rates of death, new study says

Despite efforts to improve diabetes education and self-management in the United States, a new study from Texas A&M University’s School of Public Health found that there are still large differences in diabetes-related mortality in urban and rural areas.

Possible factors include difficulties accessing medical care (particularly specialized care like endocrinology), a lack of health literacy and few avenues for improved lifestyle choices such as physical activity and proper nutrition. Nearly 10 percent of the U.S. adult population has diabetes, which ranks as the seventh-leading cause of death in the country, accounting for roughly 80,000 deaths in 2015 alone.

Previous studies have found that rural populations have a higher prevalence of diabetes, ranging around 15 to 17 percent higher in some cases, and that people in rural areas report higher levels of diabetes-related complications than their urban counterparts. However, these studies are several years old and thus do not capture recent diabetes education, management and prevention efforts.

To clarify the progress made in diabetes management over the past several years, researchers from the Southwest Rural Health Research Center at the School of Public Health produced a policy brief aimed at determining differences in hospital-based mortality rates for urban and rural patients.

The brief also explored how differences varied by region of the country.

Researchers examined hospital discharge data from 2009–14 from the Agency for Healthcare Research and Quality (AHRQ) and identified diabetes-related hospitalizations along the urban-rural continuum using the 2013 National Center for Health Statistics Urban-Rural classification scheme. The scheme outlines a range of six categories from large city core to unincorporated remote areas.

On average, there were about 38,000 diabetes-related deaths per year during the study period. The proportion of diabetes-related deaths for urban patients was 2.63 percent during the study period, whereas the rate was 2.73 percent for rural patients.

To put this in perspective, while these percentages appear to be very similar, it should be noted that just 19 percent of the United States population lives in rural areas (about 60 million), while 81 percent lives in non-rural areas (close to 266 million). Thus, the burden of diabetes-related mortality is more pronounced among the rural population.

The rural-urban split varied in the study’s four geographic regions though, with the Northeast and West regions not showing significant differences and the South and Midwest showing higher rural death rates. These differences were especially pronounced in the South, which had diabetes-related mortality rates between 14 and 21 percent in small cities and unincorporated areas.

These findings point to a need for continued interventions for rural patients and ways to address the challenges that rural health care providers face in providing routine care and promoting diabetes self-management strategies for their patients.
