Abstract

OBJECTIVE:

To estimate the incidence of type 2 diabetes in children <17 years of age and to investigate the relationship of diabetes with increasing childhood obesity in the U.K. and the Republic of Ireland (ROI).

RESEARCH DESIGN AND METHODS:

Active monthly reporting of cases by consultant pediatricians occurred through the framework of the British Pediatric Surveillance Unit, with additional reports from specialist diabetes nurses. All children <17 years of age and diagnosed by their clinician as having non-type 1 diabetes from 1 October 2004 to 31 October 2005 were included.

RESULTS:

A total of 168 confirmed cases of non-type 1 diabetes were reported, resulting in a national incidence (excluding the ROI) of 1.3 x 100,000(-1) x year(-1). Of these, 40% were diagnosed with type 2 diabetes giving a minimum incidence of 0.53 x 100,000(-1) x year(-1). Children of ethnic minorities were greatly overrepresented, with those of black and South-Asian origin (England data only) having an incidence of 3.9 and 1.25 x 100,000(-1) x year(-1), respectively, compared with 0.35 x 100,000(-1) x year(-1) in those defined as white. Of those diagnosed with type 2 diabetes, 95% were overweight and 83% obese according to International Obesity Task Force guidelines. Eighty-four percent had a family history of type 2 diabetes.

CONCLUSIONS:

Type 2 diabetes is still less common than type 1 diabetes in U.K. children. However, compared with previous prevalence data, the frequency of type 2 diabetes appears to be increasing. Incidence among ethnic minorities is far higher than in whites, as previously described in the U.S. Increased adiposity and family history of type 2 diabetes were strongly associated with the diagnosis of type 2 diabetes in U.K. children.
