The PREVCAR study is a cross-sectional investigation aimed at evaluating dietary habits among women undergoing breast cancer screening. Specifically, the study focuses on adherence to the Mediterranean diet, a dietary pattern recognized for its potential protective role against chronic diseases, including breast cancer. The PREVCAR study will include approximately 35,000 women aged 18 and older who participate in the "Prevention Caravan" and complete both the breast cancer screening and the MEDAS (Mediterranean Diet Adherence Screener) questionnaire. This 14-item questionnaire measures dietary behavior, with scores reflecting levels of adherence to the Mediterranean diet. The primary objective of the study is to determine the average MEDAS score among participants. Secondary objectives include analyzing how adherence varies across different known breast cancer risk factors-such as age, menopausal status, hormonal therapy use, and reproductive history-and assessing the prevalence of malignant breast lesions identified through the screening.

Adherence to the Mediterranean diet
Adherence to the MedDiet
To assess adherence to the MedDiet, as measured by the Mediterranean Diet Adherence Screener (MEDAS) questionnaire, among women participating in mammographic screenings organized by the "Prevention Caravan" program. Adherence to the MedDiet was evaluated using the 14-item MEDAS questionnaire (S), a validated tool designed to assess specific dietary behaviors-including the consumption of olive oil, fruits, vegetables, legumes, fish, white meat, and wine-as well as the intake of foods considered inconsistent with the Mediterranean dietary pattern, such as red meat, butter, and sugar-sweetened beverages. Each item is scored as 0 or 1 based on the participant's response, resulting in a total score ranging from 0 to 14. Higher scores indicate greater adherence: scores above 10 are classified as excellent, scores between 8 and 10 as good, and scores below 8 as poor adherence to the MedDiet.
