Associations of Mediterranean Diet, Psychological Wellbeing and Media Pressure on Physical Complexion and Effect of Weekly Physical Activity Engagement in Higher Education

Round 1

Reviewer 1 Report

This is an interesting study with high novelty. However, some points should be addrressed:

- The authors should describe with more details the enrollment of the participant by including a Flow Char Diagram-Figure

-Are ther any exclusion criteria, e.g. student with a diseases like diabetes thyroid disorders and etc.

- The author shod report if the student were from one university or from different universities.

- If the enrolled students were from one university, the authors should be reported this in the limitations section since there sample is not represantative for all university students.

- Moreover, the authos should report the type/types of studies of university student since this factor has been reported by several relevant to affect the Mediterranean Diet adherance.

- The above should also be reported in discussion section in which a comparison with other relevant studies should be performed.

- Minor english editing should be performed.

REVIEWER 1

This is an interesting study with high novelty. However, some points should be addressed:

Comment 1

- The authors should describe with more details the enrollment of the participant by including a Flow Char Diagram-Figure

Response 1

Thank you for your comment. A visual schematic has been added to summarise the process of the final sample forming the study.

Comment 2

-Are there any exclusion criteria, e.g. student with a diseases like diabetes thyroid disorders and etc.

Response 2

Thank you very much for your comment. In this case, no exclusion criteria have been established as you mention (diabetics, thyroid, disorders). Inclusion criteria have been noted. It is true that the criteria you cite are very interesting, however this research is the pilot study of an intervention project. It is true that a larger number of exclusion criteria have been established.

Comment 3

- The author shod report if the student were from one university or from different universities.

Response 3

Thank you for your comment. It has been quoted that the students are from various universities.

Comment 4

- If the enrolled students were from one university, the authors should be reported this in the limitations section since there sample is not represantative for all university students.

Response 4

Thank you for your comment. The limitation has been added

Comment 5

- Moreover, the authos should report the type/types of studies of university student since this factor has been reported by several relevant to affect the Mediterranean Diet adherance.

Response 5

Thank you very much for your comment. In this case the field of study of university students has not been analysed. As mentioned above, this research is supposed to be an initial study. It is true that for future research it would be interesting to study the students' field of study. Therefore, it has been added to the future perspectives. Despite this, a new motive for discussion has been added in relation to the branch of study of young people.

Comment 6

- The above should also be reported in discussion section in which a comparison with other relevant studies should be performed.

Response 6

Thank you very much for your comment. A new topic for discussion related to the study area has been added.

Comment 7

- Minor english editing should be performed.

Response 7

Thank you for your comment. The wording of the article has been revised.

Reviewer 2 Report

Congrats on the idea and the methodological design. But please a revision of writing must be done before publication.

Line 24: is it just nowadays that adolescence is one of the fundamental periods of human development?

Please re-write the sentences between 64-68 lines. The message is not clear and linked.

Please re-write also the sentences between lines 75-78.

I would prefer having one single general aim to study than several more specific objectives. My Opinion is that the aims are not clear to the reader at first.

Methods: own questionnaire: I suggest let the questionnaire available as supplementary material. The concept f physical activity is not clear, what exactly was considered physical activity (any body movement?)? Is the self-report of time spent in physical activities a valid measure? Since it is the most important variable of the study, please give some references to embase this method of assessment.

Results: please let it clear that significance is for all variables in the sentence at line 170.

All tables: better report the exact p-value.

The first paragraph of the discussion must show the main results and explicitly the importance of the article. Please DO NOT REPEAT the same objectives previously presented!

 

The third paragraph of the conclusion must be advice, not an affirmation based on the article.

It is not a grammatical problem, but it would be clearer with a major English revision.

Response 1

Thank you very much for your comment. The word Nowadays has been removed

Response 2

Thank you very much for your comment. The message conveyed has been rephrased

Comment 3

Thank you very much for your comment. The message conveyed has been rephrased

Comment 4

Response 4

Thank you for your comment. Only one general objective has been left

Comment 5

Methods: own questionnaire: I suggest let the questionnaire available as supplementary material. The concept f physical activity is not clear, what exactly was considered physical activity (any body movement?)? Is the self-report of time spent in physical activities a valid measure? Since it is the most important variable of the study, please give some references to embase this method of assessment.

Response 5

Thank you very much for your comment. In this case physical activity is considered to be any activity that results in a significant expenditure of energy. In this case, the question was asked about physical-sports activities. Likewise, the criteria established for the collection of this variable coincide with the WHO recommendations. In addition, the text justifies other published studies that have already used this form of measurement of weekly physical activity time.

Comment 6

Results: please let it clear that significance is for all variables in the sentence at line 170.

All tables: better report the exact p-value.

The first paragraph of the discussion must show the main results and explicitly the importance of the article. Please DO NOT REPEAT the same objectives previously presented!

Response 6

Thank you for your comments. These have been successfully implemented.

Comment 7

The third paragraph of the conclusion must be advice, not an affirmation based on the article.

Response 7

Thank you for your comment. It has been successfully implemented.

Reviewer 3 Report

Dear authors: 

-The authors need to explain the mechanism of action at the biochemical level during the physical activity period. (Comparative analysis shows that young people who engage in more than 300 236 minutes of physical activity per week show a higher degree of adherence to t
