China faces world’s largest diabetes epidemic, study says
China is now facing the world’s largest diabetes epidemic, with 11% of its population already suffering from the metabolic illness and almost 36% are pre-diabetic, a US study has found.
The survey, which included 170,287 participants and was conducted in 2013, was analyzed with the assistance of Linhong Wang from the Chinese Center for Disease Control and Prevention.
Researchers measured levels of fasting plasma glucose of each participant. Those with levels of 126 milligrams per deciliter (mg/dl) or higher were defined as diabetic while those with levels between 105 and 126 mg/dl were defined as pre-diabetic.
Hyperglycemia is a result of two anomalies – a malfunction of the pancreas which creates insulin, or the resistance of the body to this hormone.
Among the diabetic population in China, 36.5% were aware of their diagnosis and 32.2% were receiving treatment. Among those being treated, 49.2% had adequate glycemic control.
Tibetan and Muslim Chinese had significantly lower prevalence of diabetes compared to the majority Han population (14.7% for Han, 4.3% for Tibetan, and 10.6% for Muslim).
The adult diabetic rate in China of 10.9% is close to that of the United States of 9.3% according to 2014 figures recorded by the Centers for Disease Control and Prevention.
The Chinese pre-diabetic rate of 35.7% was also close to the US rate of 37% recorded in 2014.
With approximately 1.09 billion adults in China, some 388.1 million were projected to be pre-diabetic (200.4 million men and 187.7 million women).
Diabetes is a growing public health problem throughout the world.
Some 422 million adults around the world had diabetes in 2014, compared to 108 million in 1980, according to a report published by the World Health Organization in 2016.
Diabetes rates have increased more rapidly in low and middle-income countries.
Diabetes is a major cause of blindness, kidney failure, heart attacks and lower limb amputations, according to the WHO.
In 2012, an estimated 1.5 million deaths were directly caused by diabetes and another 2.2 million deaths were attributable to high blood glucose, according to the report.
