Abstract Title: 

The Mediterranean Diet is Associated with an Improved Quality of Life in Adults with Type 1 Diabetes.

Abstract: 

This study aimed to assess the potential association between dietary patterns (i.e., the Mediterranean Diet (MedDiet) and healthy eating) and patient-reported quality of life (QoL) and treatment satisfaction (TS) in adults with type 1 diabetes (T1D). A food frequency questionnaire, the Audit of Diabetes-Dependent Quality of Life (ADDQoL-19), and the Diabetes Treatment Satisfaction Questionnaire-status version (DTSQ-s) were administered via personal interviews to 258 participants with T1D. Multivariable analysis showed that a moderate or high adherence to the MedDiet was associated with greater diabetes-specific QoL (β = 0.32, 95% CI = 0.03; 0.61;= 0.029). None of the dietary quality indexes (i.e., the alternate Mediterranean Diet Score (aMED) and the alternate Healthy Eating Index (aHEI)) were associated with the overall TS. However, the aHEI was positively associated with the specific items of TS"convenience"and"flexibility"(β = 0.03, 95% CI = 0.00; 0.06;= 0.042 andβ = 0.04; 95% CI = 0.01; 0.06;= 0.011, respectively). On the other hand, the aHEI was negatively associated with the dimension"recommend to others"(β = -0.5, 95% CI = -0.99; -0.02;= 0.042). In conclusion, a moderate and high adherence to the MedDiet was associated with greater QoL. Although neither aMED nor aHEI were associated with the overall TS, some specific items were positively (i.e.,"convenience","flexibility") or negatively ("recommend to others") related to the aHEI. Further research is needed to assess how to improve medical nutrition therapy and its impact on patient-reported outcomes in people with T1D.
