People in China diagnosed with diabetes¹ in middle age lost an average nine years of life, according to a new study published Tuesday.

 

本周二发布的一份新研究显示，在中国患糖尿病的中年人一般会减寿九年。

 

The study, which appeared in the Journal of the American Medical Association (JAMA), said that inadequate² treatment, particularly in rural areas, was mainly to blame for that loss.

 

The prevalence of diabetes in China has quadrupled in the past decades, with an estimated 100 million adults now affected³ -- more than any other country worldwide, but the full eventual⁴ effect on mortality is unknown.

 

In the new study, researchers from the University of Oxford⁵ and Peking University examined the association of diabetes with mortality in 500,000 adults from 10 areas scattered⁶ throughout China, including five from rural areas and five from urban.

 

Participants were recruited between 2004 and 2008 and followed up until 2014 for cause-specific mortality.

 

At the start of the study, six percent had diabetes, including four percent from rural areas and eight percent from urban.

 

Three percent of these patients were previously⁷ diagnosed while another three percent were detected by screening.

 

The researchers found that people with diabetes had twice the risk of dying during the follow-up period in comparison with other study participants, and that these risks were higher in rural than in urban areas.
