BACKGROUND: The daily treatment of type 1 diabetes with frequent monitoring of blood glucose levels and nuisance caused by insulin administration may affect patients' health-related quality of life (HRQoL). Type 1 diabetes is further burdened with an increased risk of complications which may additionally reduce a patient's HRQoL. We aimed to assess HRQoL and its association with diabetic complications in a large sample of patients with type 1 diabetes. METHODS: Altogether, 1070 patients with type 1 diabetes (46% men, mean age 46 +/- 12 years, diabetes duration 29 +/- 13 years) from the Finnish Diabetic Nephropathy Study (FinnDiane Study) participated in this cross-sectional study. Data on HRQoL were obtained from 1023 patients using the 15D instrument. When studying nephropathy, patients were divided into groups based on their albumin excretion rate. Laser-treated patients were classified as having proliferative retinopathy. RESULTS: The mean 15D score was 0.899 +/- 0.095 with no differences between men and women. HRQoL decreased with increasing age among patients with and without diabetic complications. In the Tobit regression model, macroalbuminuria (-0.036), dialysis (-0.082), renal transplant (-0.053), poor glycemic control (-0.006), ageing (-0.002) and longer diabetes duration (-0.001) explained the reduction in HRQoL. In a corresponding model, the presence of proliferative retinopathy did not have a significant negative influence on HRQoL. Of individual dimensions of the 15D instrument, nephropathy affected all but five dimensions, while retinopathy affected vision, mobility, eating and usual activities. CONCLUSIONS: The 15D scores decreased with increasing age. The presence of nephropathy, but not retinopathy, reduced the subjective HRQoL in patients with type 1 diabetes.
