- Aims/hypothesis. To analyse the incidence of Type I (insulin-dependent) diabetes mellitus in the 0-34 years age group in Sweden 1983-1998. Methods. Incidence and cumulative incidence per 100 000 and Poisson regression analysis of age-period effects was carried out using 11 751 cases from two nation-wide prospective registers. Results. Incidence (95%-CI) was 21.4 (20.8-21.9) in men and 17.1 (16.6-17.5) in women between 0 and 34 years of age. In boys aged 0-14 and girls aged 0-12 years the incidence increased over time, but it tended to decrease at older age groups, especially in men. Average cumulative incidence at 35 years was 748 in men and 598 in women. Cumulative incidence in men was rather stable during four 4-year periods (736, 732, 762, 756), while in women it varied more (592, 542, 617, 631). In males aged 0-34 years, the incidence did not vary between the 4-year periods (p=0.63), but time changes among the 3-year age groups differed (p<0.001). In females the incidence between the periods varied (p<0.001), being lower in 1987-1990 compared to 1983-1986, but time changes in the age groups did not differ (p=0.08). For both sexes median age at diagnosis was higher in 1983-1986 than in 1995-1998 (p<0.001) (15.0 and 12.5 years in males, 11.9 and 10.4 in females, respectively). Conclusion/interpretation. During a 16-year period the incidence of Type I diabetes did not increase in the 0-34 years age group in Sweden, while median age at diagnosis decreased. A shift to younger age at diagnosis seems to explain the increasing incidence of childhood Type I diabetes.

The risk for diabetic nephropathy is low in young adults in a 17-year follow-up from the Diabetes Incidence Study in Sweden (DISS). Older age and higher BMI at diabetes onset can be important risk factors

- AimsThe main objective of this study was to estimate the occurrence of diabetic nephropathy in a population-based cohort of patients diagnosed with diabetes as young adults (15-34years). MethodsAll 794 patients registered 1987-1988 in the Diabetes Incidence Study in Sweden (DISS) were invited to a follow-up study 15-19years after diagnosis, and 468 (58%) participated. Analysis of islet antibodies was used to classify type of diabetes. ResultsAfter median 17years of diabetes, 15% of all patients, 14% T1DM and 25% T2DM, were diagnosed with diabetic nephropathy. Ninety-one percent had microalbuminuria and 8.6% macroalbuminuria. Older age at diagnosis (HR 1.05; 95% CI 1.01-1.10 per year) was an independent and a higher BMI at diabetes diagnosis (HR 1.04; 95% CI 1.00-1.09 per 1kg/m(2)), a near-significant predictor of development of diabetic nephropathy. Age at onset of diabetes (p=0.041), BMI (p=0.012) and HbA1c (p<0.001) were significant predictors of developing diabetic nephropathy between 9 and 17years of diabetes. At 17years of diabetes duration, a high HbA1c level (OR 1.06; 95% CI 1.03-1.08 per 1mmol/mol increase) and systolic blood pressure (OR 1.08; 95% CI 1.051.12 per 1mmHg increase) were associated with DN. ConclusionsPatients with T2DM diagnosed as young adults seem to have an increased risk to develop diabetic nephropathy compared with those with T1DM. Older age and higher BMI at diagnosis of diabetes were risk markers for development of diabetic nephropathy. In addition, poor glycaemic control but not systolic blood pressure at 9years of follow-up was a risk marker for later development of diabetic nephropathy. Copyright (c) 2014 John Wiley & Sons, Ltd.

- All incident cases of diabetes mellitus in the age group 15 to 34 years have been prospectively registered in Sweden since January 1983. To analyse the utilization of outpatient services 8 years after disease onset, we selected the cases registered in 1983 and two controls per case from the general population, matched by age, gender, and county of residence. In 1991, retrospective data about utilization patterns during a 3-month period were collected via a mailed questionnaire, returned by 317 (72%) patients with diabetes and 586 (68%) controls. Seventy-four percent of the cases and 19% of the controls reported at least one visit to a hospital outpatient clinic, including accident and emergency departments. The odds ratio for one visit was 14 (95% CI 9.6-20), for two visits 11 (95% CI 7.0-18), and for three or more visits 8.9 (95% CI 5.6-14). Even when specialized diabetes clinics were excluded from the analysis, the cases had higher odds for visits to internal medicine clinics, to ophthalmology clinics, and to gynaecology clinics, but not for visits to surgical clinics or to accident and emergency departments. Of non-hospital outpatient services, only visits to nurse practitioners were reported by a higher percentage of diabetic responders. Twenty-seven percent of patients with diabetes, as compared to 9% of the controls, had visited both hospital and non-hospital outpatient offices. Females were overrepresented among diabetic high-consumers. The results indicate that most young to middle-aged Swedish persons with diabetes are monitored at hospital outpatient offices, but considerable overlap exists between hospital and non-hospital outpatient services. Further research is needed into the determinants of utilization patterns in diabetes, such as gender.
