47% in China Likely Have Prediabetes Or Diabetes
Over 10% of China's population has diabetes -- one of the high prevalence rates in the world -- and more than a third are likely to be prediabetic, according to a new nationally representative study.
Led by Limin Wang, MPH, of the Chinese Center for Disease Control and Prevention in Beijing, and colleagues, the analysis reported the estimated standardized prevalence for diabetes among China's population for 2013 was pegged at 10.9% (95% CI 10.4%-11.5), which included diagnosed (4%, 95% CI 3.6%-4.3%) and undiagnosed cases of diabetes.
Published in the Journal of the American Medical Association, the prevalence of China's prediabetes population was estimated at 35.7% (95% CI 34.1%-37.4%).
Compared to the U.S., which had a combined diabetes and prediabetes estimate of 49%-52% between 2011-2012, China was only slightly lower with a combined 47% prevalence rate in 2013.
Following a nationwide survey conducted in 2010, China's prediabetes prevalence was estimated at 50.1%, while their diabetes prevalence was estimated at 11.6%. However, Wang's group suspected these numbers overestimated the true prevalence, and therefore aimed to do better in their current study.
The research group drew on data from 170,287 adults who participated in the China Chronic Disease and Risk Factors Surveillance study, conducted every three years. The survey included an in-depth questionnaire to gather information on lifestyle risk factors, medical history, and demographics, as well as physical and lab evaluations (similar to NHANES in the U.S.).
All participants not previously diagnosed with diabetes u Continue reading
