Diabetes Tied to Greater Death Risk in China
Diabetes was linked to a rise in all-cause and cause-specific mortality among a Chinese population, researchers stated.
The nationwide study of people in rural and urban areas of China reported a significant association between diabetes and all-cause mortality compared to those without diabetes (1,373 versus 646 deaths/100,000 adjusted rate ratio 2.00, 95% CI 1.93-2.08), which resulted in an average of 9-year shorter lifespan, according to Fiona Bragg, DPhil, of the University of Oxford in England, and colleagues.
Although prevalence rates of diabetes were higher among urban areas of China, mortality rates were higher in rural areas (rural RR 2.17, 95% CI 2.07-2.29), they wrote in the Journal of the American Medical Association.
The authors also found a link between an increased risk for several cardiovascular and non-cardiovascular cause-specific mortalities associated with diabetes.
China, which has one of the highest rates of diabetes in the world with an estimated 110 million individuals affected, has experienced a rapid increase in diabetes prevalence over the past few decades, explained Bragg in an interview with MedPage Today.
"Because the increase in diabetes prevalence in China is recent, the full effect on mortality is unknown. Most previous studies looking at the impact of diabetes on mortality have been in high-income countries where diabetes is generally relatively well managed. It is not clear that the findings of these studies can be applied to China, where there are important differences in diabetes and its management compared with the West," she stated.
