[BDSP. Notice produite par INIST-CNRS 4uvXR0x5. Diffusion soumise à autorisation]. Objectives. This study was undertaken to examine the trends in the diagnosis of Type 2 diabetes mellitus among children and adolescents with new-onset diabetes seen from 1994 through 1998 at the three university-based diabetes centers in Florida. Methods. Data were abstracted from medical records and patients were categorized as having Type 1 or Type 2 diabetes. Results. There were 569 patients classified with Type 1 diabetes and 92 with Type 2 diabetes. The proportion of patients diagnosed with Type 2 diabetes increased over the five years from 9.4% in 1994 to 20.0% in 1998 (chi-square test for trend=8.2 ; p=0.004). There was not an associated net increase in the total number of new diabetes patients referred over time (chi-square test for trend=0.6, p=0.4). Those with Type 2 diabetes were more likely to have a body mass index in the 85th-94th percentile [odds ratio (OR)=8.5 ; 95% confidence interval (Cl) 2.5,28.8], have a body mass index>=95th percentile (OR=6.8 ; 95% Cl 2.6,17.7), Hispanic ethnicity (OR=6.2 ; 95% Cl 2.2,17.9), black race (OR=2.8 ; 95% Cl 1.3,6.2), female gender (OR=2.2 ; 95% Cl 1.2,4.3), and older age (OR=1.4 for each one-year increment in age ; 95% Cl 1.3,1.6), compared with those having Type 1 diabetes. Conclusions. From 1994 through 1998, there was a significant overall increase in the percentage of children referred with new-onset diabetes who were considered to have Type 2 diabetes. Factors associated with the diagnosis of Type 2 diabetes relative to Type 1 diabetes include body mass index>=85th percentile, Hispanic ethnicity, black race, female gender, and older age.
