Factors Associated with Adherence to the Mediterranean Diet and Dietary Habits among University Students in Lebanon

Although the Mediterranean Diet has been acknowledged as the best overall diet for the year 2020, it has seen a decrease in its adherence over the past years. This is due to several reasons, one of which is the gradual shift to a more westernized diet with all the influences that occur especially on university students whose dietary choices set a path for future dietary habits. The aim of this study is to check the level of adherence to the Mediterranean Diet and frequency of breakfast consumption among university students in Lebanon and check whether they are influenced by sociodemographic, anthropometric, dietary knowledge, or academic data. A cross-sectional questionnaire was electronically sent to randomly selected students (210 females and 93 males) from different universities across Lebanon, aged between 18 and 25 years old. The questionnaire was filled online, and all data were self-reported. The Mediterranean Diet Quality Index (KIDMED) was used as a tool to evaluate adherence to the Mediterranean Diet. The results showed that 18.8% of respondents had high adherence to the Mediterranean Diet. Students who reported always consuming breakfast and not skipping meals had significantly higher adherence to the MD. Furthermore, students with lower BMI and higher KIDMED scores had significantly more correct answers on the nutritional knowledge questions. In addition, there was a significant difference in the average KIDMED scores between different GPA categories, most notably when comparing high and poor MD adherence; students with excellent GPA scores had higher adherence to the MD than those with poor GPA scores. In conclusion, nutrition awareness in a university setting is very important since it may positively affect academic outcomes and may be the last chance to teach and engrave healthy eating patterns to a large scale of students.

Students who always eat breakfast and do not skip meals have higher adherence to the Mediterranean Diet, and students with lower BMI and higher nutritional knowledge scores are more likely to answer nutritional knowledge questions correctly.
