Introduction: This cross-sectional study investigated the association between diabetes diet-related quality of life (QoL) and diet intake in people with type 2 diabetes (T2D) (67.5±10.7 years and 62.2% men).

Methods: Diabetes diet-related QoL and nutritional intake were evaluated using the DDRQoL-R-9, including satisfaction with diet, perceived merits of diet therapy, and burden of diet therapy, and brief-type self-administered diet history questionnaire.

Results: Table shows that perceived merits of diet therapy were positively correlated with glycemic control, although burden of diet therapy was negatively correlated with glycemic control and that dietary fiber intake was negatively correlated with burden of diet therapy, although positively correlated with perceived merits of diet therapy. Dietary fiber intake was associated with perceived merits of diet therapy (β = 0.390, p < 0.001), burden of diet therapy (β = −0.215, p = 0.013), and satisfaction with diet (β = 0.177, p = 0.036), after adjusting for covariates.

Discussion: People who have poor glycemic control despite diet therapy may have been overburdened by the diet therapy. High dietary fiber intake may affect increased burden of diet therapy although the perceived benefits of the diet therapy.

Conclusion: Dietary fiber intake is associated with diabetes diet-related QoL in people with T2D.
