Aims/hypothesis The aim of this study was to describe the prevalence of complications, health-related quality of life (HRQOL) and the influence of beliefs about control over health in diabetic dialysis patients. Methods Of 53 eligible diabetic patients on chronic dialysis during January 2004 in our clinic, 38 (76%) completed a kidney-specific (Kidney Disease Quality of Life) and a generic (SF-36) questionnaire and were characterised in terms of cardiovascular diseases and diabetic complications. Matched groups of non-diabetic dialysis patients (n= 40) and diabetic patients with a long duration of diabetes and normal kidney function (n=38) served as controls. Generic HRQOL was compared with matched data from a survey on the Danish general population (n=2248).
