Relationship between adherence to the Mediterranean diet, sustainable and healthy eating behaviors, and climate change awareness: A cross-sectional study from Turkey.

Objectives: This study aimed to evaluate the relationship between adherence to the Mediterranean diet, sustainable and healthy eating behaviors, and climate change awareness in adults.

Methods: This descriptive and cross-sectional study was conducted with 1797 adults ages 19-65 y. Demographic characteristics, anthropometric measurements, adherence to the Mediterranean diet, sustainable and healthy eating behaviors, and climate change awareness were ascertained through a questionnaire.

Results: The mean age of the individuals was 27.5 ± 11.76 y, and 50.5% of the participants were adherent to the Mediterranean diet. A statistically significant difference was found between individuals who did and did not adhere to the Mediterranean diet in terms of age, income status, total score and subscores on the Sustainable and Healthy Eating Behaviors Scale, and subscores for information on climate change causes (P < 0.05). A statistically significant positive correlation was found between the Mediterranean Diet Adherence Scale (MEDAS) total score, the Sustainable and Healthy Eating Behaviors Scale total score and subscores, and the Climate Change Awareness Scale total score and subscores (P < 0.05). It was determined that sex, education level, and income status affected the Climate Change Awareness Scale total score (P < 0.05). It was determined that age, income status, the Sustainable and Healthy Eating Behaviors Scale total score, and the Climate Change Awareness Scale total score affected the MEDAS total score (P < 0.05). Also, it was determined that age, sex, education level, MEDAS total score, and Climate Change Awareness Scale total score affected the Sustainable and Healthy Eating Behaviors Scale total score (P < 0.05).

Conclusions: This study showed a significant effect of climate change awareness on sustainable and healthy eating behaviors and adherence to the Mediterranean diet.
