New research suggests that the incidence of type 1 diabetes (T1D) is rising in Europe, with experts warning that if trends continue, incidence would double in the next 20 years.

As part of the study, published in Diabetologia, researchers analysed age and sex-standardised T1D incidence rates for more than 84,000 children reported for 26 European centres, representing 22 countries that had registered newly diagnosed individuals in geographically defined regions for up to 25 years during the period 1989-2013.

While several centres in high-incidence countries showed reducing rates of increase in more recent years, a pooled analysis across all centres revealed a 3.4 per cent (95% CI 2.8%-3.9%) per annum increase in incidence rates, although there was some suggestion of a reduced rate of increase in the 2004-2008 period. 

Rates of increase were similar in boys and girls in the 0- to 4-year-old age group and in the 5- to 9-year-old age group, but were higher in boys than girls in the 10- to 14-year-old age group. 

The authors noted four centres showed support for a cyclical pattern of incidence with a four-year periodicity, but could not find a plausible reason for this variation.
