ARTICLE HIGHLIGHTS
Research background

Non-alcoholic fatty liver disease (NAFLD) is a progressive disease that can lead to complications such as liver fibrosis, cirrhosis, hepatocellular carcinoma, cardiovascular diseases, and metabolic disorders such as type 2 diabetes. However, to date, no medications have been approved for treating NAFLD, and lifestyle modifications remain the cornerstone of treatment.

Research motivation

Changing an unhealthy lifestyle can be useful for alleviating hepatic steatosis in patients with NAFLD. However, not everyone is able or willing to adhere to the dietary and exercise guidelines. The variety of exercise and dietary controls makes it challenging to quantify and evaluate patient’s adherence.

Research objectives

To evaluate adherence effectively and swiftly with the recommendations for lifestyle changes in patients with NAFLD, implementing various intervention strategies based on adherence levels to prevent disease progression is crucial.

Research methods

First, we identified factors affecting exercise and dietary adherence in patients with NAFLD. The Delphi method was used to analyze and modify the Exercise and Diet Adherence Scale (EDAS). After a preliminary small-scale survey and further adjustments, the EDAS was established. Enrolled patients with NAFLD followed exercise and diet interventions, filled the EDAS at the beginning, and were followed up for 6 months. Finally, we evaluated and validated the reliability of the EDAS.

Research results

The EDAS demonstrated good item discrimination; internal consistency reliability; test-retest reliability; and content, construct, and criterion validity. It can reliably measure the adherence of patients with NAFLD to exercise and dietary interventions.

Research conclusions

The EDAS has been established to assess the adherence of patients objectively, directly, and rapidly with NAFLD to changing unhealthy lifestyles. This reliable tool supports early intervention in NAFLD, aims to prevent disease progression, and reduces the healthcare burden.

Research perspectives

EDAS plays an important clinical role in the assessment, treatment, and management of NAFLD. However, its widespread application requires multicenter prospective studies. Additionally, the participants in this study did not undergo a liver biopsy. Thus, future research should explore the impact of EDAS on liver pathology.
