Quality of life in Danish children and adolescents with type 1 diabetes treated with continuous subcutaneous insulin infusion or multiple daily injections

•Children on CSII or MDI for less than one year reports nearly equal HRQoL.•Children on CSII for more than one year reports better HRQoL compared to children on MDI.•Particularly, generic HRQoL is rated high by children on CSII for more than one year.

SummaryAimsThe aims of the study were to compare health-related quality of life (HRQoL) in a National Danish population of children and adolescents with type 1 diabetes (T1D) treated with either continuous subcutaneous insulin injection (CSII) or multiple daily insulin injections (MDI), and to investigate whether HRQoL assessments were influenced by treatment duration.MethodsParticipants were recruited through the Danish Registry for Diabetes in Childhood and Adolescence. A total of 700 children and adolescents (360 girls), 8-17 years, were included. Of these, 295 were treated with CSII (160 for more than one year) and 405 with MDI (238 for more than one year). Participants and their parents completed the Pediatric Quality of Life Inventory Diabetes and Generic Module. HbA1c was analyzed centrally.ResultsParents reported children and adolescents on CSII for more than one year to have less diabetes-related symptoms and worry, less problems in communicating diabetes, and better generic functioning compared with those on MDI. Children and adolescents on CSII for more than one year reported less diabetes-related symptoms, but more treatment problems, and better generic functioning in all subscales except social functioning compared with those on MDI for more than one year. Comparing those on CSII and MDI for less than one year, no differences in HRQoL ratings were found, apart from better rating of treatment barriers in the MDI group.ConclusionsThis Danish national study on HRQoL in children and adolescents on CSII or MDI showed better HRQoL in children and adolescents on long time CSII, particularly concerning generic HRQoL.
