Increasing body mass index at diagnosis of diabetes in young adult people during 1983-1999 in the Diabetes Incidence Study in Sweden (DISS)

• Objective. To study trends in body mass index (BMI) at diagnosis of diabetes in all young Swedish adults in the age range of 15-34 years registered in a nation-based registry. Design. The BMI was assessed at diagnosis in diabetic patients 15-34 years of age at diagnosis, for a period of 17 years (1983-1999). Islet cell antibodies (ICA) were measured during three periods (1987-1988, 1992-1993 and 1998-1999). Setting. A nationwide study (Diabetes Incidence Study in Sweden). Subjects. A total of 4727 type 1 and 1083 type 2 diabetic patients. Main outcome measures. Incidence-year specific BMI adjusted for age, gender and time of diagnosis (month). Results. Body mass index at diagnosis increased significantly both in type 1 (21.4 ▒ 3.6 to 22.5 ▒ 4.0: P < 0.0001) and in type 2 (27.4 ▒ 6.8 to 32.0 ▒ 6.0, P < 0.0001) diabetic patients, also when adjusted for age, gender and month of diagnosis. A similar significant increase in BMI was found in type 1 diabetic patients and in type 2 diabetic patients in the periods 1987-1988, 1992-1993 and 1998-1999, years when ICA were assessed and considered in the classification of diabetes. Despite this increase in BMI, there was no increase in the incidence of diabetes in young-adult people in Sweden. Conclusion. Body mass index at diagnosis of diabetes in subjects 15-34 years of age has substantially increased during 1983-1999 in Sweden when adjusted for age, gender and month of diagnosis.
