Diet, exercise can delay diabetes for years: study

By Michael Kahn

LONDON (Reuters) - Drinking less alcohol, eating more vegetables and exercising can prevent or delay the onset of diabetes, researchers said on Friday in a study showing that lifestyle changes can make a big difference.

Diet and exercise reduced the incidence of diabetes by about 43 percent over 20 years among 577 high-risk Chinese adults, the researchers reported in the journal Lancet.

At the end of the 20 years, 80 percent of those who changed what they ate and exercised more had diabetes, compared with 93 percent who made no changes, said Guangwei Li of the China-Japan Friendship Hospital in Beijing and Ping Zhang at the U.S. Centers for Disease Control and Prevention.

The findings came as part of a series of studies addressing new research about diabetes, which affects 246 million adults worldwide, and accounts for 6 percent of all global deaths.

"The challenge is to translate research findings into substantial clinical improvements for patients. Although prospects are hopeful, they are not assured," the Lancet wrote in a commentary.

Type 2 diabetes accounts for about 90 percent of all diabetes cases and is closely linked to obesity and physical inactivity. Type 1 diabetes is an auto-immune disease often diagnosed at an early age.

The International Diabetes Federation estimates more than 380 million people will have a form of diabetes by 2025 as more developing nations adopt a Western lifestyle.

The researchers followed 577 Chinese adults at risk of diabetes over a 20-year period to see how prodding people to change their lifestyles could affect their health.
