The Effects of Diabetes Self-Management Education on Quality of Life for Persons With Type 1 Diabetes: A Systematic Review of Randomized Controlled Trials.

Thirteen of the 17 studies had a high risk of bias for quality-of-life outcomes, mainly because outcome data were missing. Only 6 studies made quality of life the primary outcome, and most studies treated it as a secondary outcome, so the quality-of-life findings may be less reliable. The interventions were bundles of monitoring, medication, healthy eating, activity, coping, problem solving, and risk reduction, so the effect of any single component cannot be separated. Quality-of-life tools varied widely, and several studies used generic rather than diabetes-specific measures, making results hard to compare. Participants were mostly children and young adults, with an average age of 22.9 years and an oldest adult of 51 years, so the review says little about older adults with type 1 diabetes. Female participants were oversampled at 54.8%, and race or ethnicity was inconsistently reported, which limits generalizability. One trial found worse quality of life in children who received a self-study kit, so education format matters and not all diabetes education is helpful. The review included only randomized or case-controlled trials, so it may miss real-world studies that could show how these programs work in routine care.

The supplied publication types list research support from non-U.S. government and NIH extramural funding. The article text does not state author conflicts of interest.

Do not conclude that diabetes self-management education reliably improves quality of life. Only 7 studies detected significant improvement, and 13 of the 17 studies had a high risk of bias for quality-of-life outcomes, mainly because outcome data were missing. The interventions were bundles of education, monitoring, medication, coping, diet, activity, and problem solving, so the effect of any single component cannot be separated.
