EASD 47th Annual Meeting
LISBON — The incidence rate of type 1 diabetes in European children has increased by about 4% each year, according to registry data collected from 1989 to 2008.
During 20 years, 20 of 21 registries in 15 European countries showed significant rates of increase in the incidence of childhood type 1 diabetes diagnosed before age 15 years. The trend persisted when the median rate of increase was estimated for the first half of registry data (1989-1998) and for the second half (1999-2008).
From 1989 to 1993, incidence rates of type 1 diabetes ranged from 3.2 per 100,000 people in the Former Yugoslav Republic of Macedonia to 25.8 per 100,000 people in Stockholm, Sweden. From 2004 to 2008, these two regions again had the lowest and highest incidences of type 1 diabetes; however, rates increased to 5.8 per 100,000 people and 36.6 per 100,000 people, respectively.
The researchers cautioned that “the increase in a registry is not necessarily uniform with periods of less rapid and more rapid increase in incidence occurring in some registries. ...This pattern of change suggests that important risk exposures differ over time in different European countries. Further time trend analysis and comparison of the patterns in defined regions is warranted.”
These figures are from the first 20 years of registration. The 21 registries involved continue to submit registration data, researchers said.
