Abstract
Context: Diet quality is directly related to glycemic control in individuals with type 2 diabetes mellitus (T2DM). The use of dietary indices can provide a comprehensive understanding of the relationship between diet quality and clinical outcomes.
Objective: The aim was to evaluate the relationship between diet quality, measured using dietary indices, and its impact on improving glycemic control in individuals with T2DM through health interventions.
Data source: This study was conducted using 6 databases, including Web of Science, MEDLINE (via PubMed), Embase, Bireme, Scopus, and Cumulative Index to Nursing and Allied Health Literature (CINAHL), as well as the gray literature (Google Academic).
Data extraction: Randomized clinical trials that evaluated the effectiveness of health interventions in adult and older adult individuals with T2DM and presented data on diet quality evaluated using dietary indices and the percentage of glycated hemoglobin (%HbA1c) were included.
Data analysis: A total of 3735 articles were retrieved, 4 of which were included in the study selection stages. The quality indices assessed in the studies were the Alternate Healthy Eating Index (AHEI), Healthy Eating Index-2010 (HEI-2010), Diet Quality Index-International (DQI-I), and Diet Quality Index-Revised (DQI-R). A reduction in %HbA1c was observed in 2 studies, which correlated with the AHEI and DQI-I scores in the intervention groups. The approach of using food labels to improve diet quality reduced %HbA1c by 0.08% in the intervention group compared with the control group. Only 1 study found no significant association between the DQI-R index and %HbA1c. Additionally, negative correlations were observed between body weight and the AHEI and DQI-I scores.
Conclusion: Health interventions improved diet quality, glycemic control, and weight loss in individuals with T2DM.
