What does the Mediterranean Diet Adherence Screener assess?
The Mediterranean Diet Adherence Screener (MEDAS), often implemented as the medas 14-item questionnaire, is a validated tool designed to quantitatively assess an individual’s adherence to the Mediterranean diet. It evaluates specific dietary components such as consumption of fruits, vegetables, olive oil, fish, and red wine, assigning a MEDAS diet score that reflects the degree of alignment with dietary recommendations. The primary purpose of the tool is to facilitate the identification of dietary patterns associated with reduced risk of cardiovascular disease, metabolic syndrome, and other chronic conditions. Utilization of the MEDAS screener and associated scoring methods, including the Mediterranean diet score calculator, supports clinicians and researchers in dietary assessment and epidemiological studies, enabling a standardized approach to monitor compliance and guide nutritional interventions.
For which type of patients or populations is the Mediterranean Diet Adherence Screener intended?
The Mediterranean Diet Adherence Screener (MEDAS) is primarily indicated for adult patients at risk of or diagnosed with cardiovascular diseases, type 2 diabetes mellitus, and metabolic syndrome. It serves as a validated tool to quantify adherence to the Mediterranean dietary pattern through the medas 14-item questionnaire, facilitating nutritional assessment in both primary prevention and secondary clinical settings. The screener’s utility is most pronounced in lifestyle intervention programs aimed at reducing cardiometabolic risk factors, where monitoring dietary compliance is essential. Its application extends to outpatient and community health environments, supporting personalized dietary counseling by enabling rapid calculation of the MEDAS diet score.
Step-by-Step Explanation of the Mediterranean Diet Adherence Screener
The Mediterranean Diet Adherence Screener (MEDAS) consists of 14 items designed to evaluate dietary patterns consistent with the Mediterranean diet. Each item addresses specific food groups or habits, including the consumption of olive oil, fruits, vegetables, nuts, legumes, fish, and meat products. Questions typically employ a binary response format (yes/no) or categorical frequency scales to quantify adherence levels. Respondents indicate their usual intake over the past month, allowing clinicians to assess the degree of compliance with Mediterranean dietary recommendations. Scoring is straightforward, with each item scored as 0 or 1, culminating in a total score ranging from 0 to 14, where higher scores reflect greater adherence, which is associated with reduced risk of cardiovascular diseases and metabolic disorders.

Downloadable resources in both the original and English versions of the Mediterranean Diet Adherence Screener are provided below in PDF format. These include the medas 14-item questionnaire along with detailed guidelines to facilitate accurate assessment of adherence to the Mediterranean dietary pattern. Utilizing these tools, healthcare professionals can efficiently compute the MEDAS diet score, which aids in evaluating dietary habits linked to the prevention and management of cardiovascular diseases and metabolic disorders. The availability of the Mediterranean diet checklist ensures standardized scoring and supports consistent patient monitoring.
How to interpret the results of the Mediterranean Diet Adherence Screener?
The Mediterranean Diet Adherence Screener (MEDAS) score ranges from 0 to 14, with higher scores indicating greater compliance with the dietary pattern known to reduce the risk of cardiovascular disease and type 2 diabetes. Scores ≥9 typically reflect optimal adherence, associated with significant health benefits, while scores ≤6 suggest low adherence, signaling the need for dietary intervention. The calculation involves summing individuals’ affirmations to 14 dietary components, each scored as 0 or 1, therefore: MEDAS score = Σ (component scores). Healthcare professionals should interpret results by considering this threshold; a low score emphasizes the urgency for tailored nutritional counseling aimed at improving intake of fruits, vegetables, whole grains, and healthy fats. In practice, the MEDAS score serves as a validated tool for identifying patients at risk due to suboptimal diets, enabling timely preventive measures to mitigate the prevalence of metabolic disorders.
What scientific evidence supports the Mediterranean Diet Adherence Screener ?
The Mediterranean Diet Adherence Screener (MEDAS) was developed during the PREDIMED study, a landmark randomized controlled trial initiated in Spain to evaluate the effects of the Mediterranean diet on cardiovascular health. Validation studies have demonstrated that MEDAS reliably quantifies adherence by assessing consumption patterns of key components such as olive oil, nuts, fruits, and vegetables. Research consistently associates higher MEDAS scores with reduced incidence of cardiovascular disease, type 2 diabetes, and metabolic syndrome. Additionally, cross-sectional and longitudinal analyses confirm the tool’s sensitivity and specificity in capturing dietary patterns linked to decreased inflammation and overall mortality risk, supporting its utility in both clinical and epidemiological settings.
Diagnostic Accuracy: Sensitivity and Specificity of the Mediterranean Diet Adherence Screener
The Mediterranean Diet Adherence Screener (MEDAS) has demonstrated a sensitivity ranging from approximately 70% to 85% and a specificity between 60% and 80% in identifying individuals with high adherence to the Mediterranean diet. These metrics vary depending on the population studied and the reference method employed, such as food frequency questionnaires or biomarkers. Notably, the MEDAS effectively distinguishes dietary patterns associated with reduced risk of cardiovascular disease and metabolic syndrome, supporting its utility in both clinical and epidemiological settings. The balance between sensitivity and specificity allows for reliable screening while minimizing false positives and negatives.
Related Scales or Questionnaires
The Mediterranean Diet Adherence Screener (MEDAS) is closely related to several validated tools such as the MEDAS 14-item questionnaire, the Mediterranean Diet Score Calculator, and the Mediterranean Diet Checklist, each designed to quantify adherence to the Mediterranean dietary pattern. These scales, also explained and available for download on ClinicalToolsLibrary.com, offer complementary approaches with slight variations in item number and scoring methods. Advantages of the MEDAS include its brevity, ease of administration, and robust validation in populations at risk for cardiovascular disease and metabolic syndrome. In contrast, longer questionnaires may provide more detailed dietary intake assessment but at the expense of increased respondent burden and reduced feasibility in clinical settings. Some clinical tests integrate biochemical markers to enhance objectivity but require additional resources. The MEDAS diet score remains a practical choice given its balance between simplicity and predictive validity for chronic disease prevention.
