Determining the relationship between diet inflammatory index, mental status and quality of life in type 2 diabetes: a cross-sectional study

Abstract

Purpose Diabetes is one of the health problems of increasing importance owing to the increase in its incidence and the problems it causes, and it is closely related to nutrition. This study aims to determine the relationship between the dietary inflammatory index (DII) scores of individuals with type 2 diabetes, depression, anxiety and quality of life. Design/methodology/approach In this cross-sectional study, 158 individuals with type 2 diabetes who applied to a nutrition and diet outpatient clinic of a private hospital in Istanbul were included. Their depression status was evaluated using the Beck Depression Inventory; their anxiety status was evaluated using the Beck Anxiety Inventory; and their quality of life was evaluated using the Short Form 36 Quality of Life scale. One-way ANOVA test was used to define the difference between groups. All test results were evaluated at a significance level of 0.05. Findings There was no significant relationship between DII scores, depression (p = 0.814) and anxiety (p = 0.817). However, a significant decrease was observed in the scores of the quality of life criterion in the groups with high depression and anxiety scores (p < 0.05). In addition, participants with high anxiety states had higher HbA1c levels (p = 0.043). Originality/value Individuals in this sample with no known psychiatric diagnosis or treatment history demonstrated a significant relationship between depression and anxiety scores and quality of life.
