Changed criteria for diabetes need further research

In 1997 the American Diabetes Association changed the diagnostic fasting plasma value for glucose from 7.8 to 7.0 mmol/l. For screening and epidemiological studies they no longer recommended the standard 75 g oral glucose tolerance test recommended by the WHO. The DECODE Study Group's reanalysis of epidemiological studies in eight European countries---more than 26 000 patients---found that the two diagnostic criteria agreed in only 431 of 1517 people classified as diabetic (p 371). Because of this reclassification the group says that the WHO should wait for results of further reanalyses, with focus on prognostic impact, before it considers adopting the ADA criteria.
