The data should be provided as part of the manuscript or its supporting information, or deposited to a public repository.

5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: Thanks the authors for bringing such interesting study to the scientific community. I have forwarded my comments regarding the study as follows:-

1. The authors have described the variables and definitions of the study in their manuscript. But it is not clear whether these are adapted or adopted.

2. The manuscript lacks in defining some variables for example; Consuming Behavior, Perception about Environmental Factors and Mindfulness Practice.

3. The study also lacks in showing how the academic performance of the study participants are scored and measured?

4. Information regarding sample (sample size and sampling) should be clearly stated before the result of the study.

5. If the authors have checked the validity and reliability of the tool, there is the need to display internal validity and test-retest reliability, with the Cronbach’s α.

6. Do the authors display the crude and adjusted odds ratio in one table for the better examinations of the association between outcome variable and the predictor variables?

Reviewer #2: It is an honour to review the manuscript. This is an interesting study on “Factors Influencing Secondary School 1 Students' Nutrition, Mindfulness, and 2 Academic Performance in Nan Province, Thailand”.

My comments are appended.

Abstract:

Abstract is too long, it is better to shorten.

Introduction:

Introduction has been written in right direction. However, in my opinion it is better to put some background information or research from Thailand to draw rationale or knowledge gap.

Methods:

Methods has been written in right direction.

Results:

Results has been written in right direction.

Discussion:

Discussion has been written in right direction. The author needs to put some limitations and strength of this study.

Revision 1

'Point-by-point response to editors and reviewers'

According to comments, we agreed and corrected with all the comments raised by the editors and reviewers. We would like to take this opportunity to express our sincere thanks to editor and reviewers who identified areas of our manuscript that needed corrections or modification. We would like also to thank you for allowing us to resubmit a revised copy of the manuscript.

Reviewer #1:

The reviewer noted that while the authors described the variables and definitions of the study in their manuscript, it was not clear whether these were adapted or adopted.

Author's Response: We clarified their measures as follows:

Anthropometric measurements: Adopted from WHO standards (2007)

Nutritional knowledge: Adapted from Thailand's five food groups guidelines

Attitude About Food Intake: Self-developed using a five-point Likert scale

Consuming Behavior: Self-developed to assess eating habits and food choices

Perception About Environmental Factors: Self-developed using a five-point Likert scale

Mindfulness Practice: Adopted the Child and Adolescent Mindfulness Measurement (CAMM) by Greco et al. (2011)

Academic performance measurement: Adopted the standard GPA categorization used in the Thai education system

We revised the manuscript to clearly indicate these origins with appropriate citations.

The reviewer pointed out that the manuscript lacked definitions for some variables, such as Consuming Behavior, Perception about Environmental Factors, and Mindfulness Practice.

Author's Response: We added clearer definitions for these variables in the methodology section.

The reviewer noted that the study lacked information on how academic performance was scored and measured.

Author's Response: We added a detailed description of how academic performance was assessed, including the use of the previous year's grades and the standard Thai education system GPA categorization.

The reviewer suggested that information regarding sample size and sampling should be clearly stated before the results of the study.

Author's Response: We added a new section in the Materials and Methods describing their study population and sampling approach.

The reviewer asked about the validity and reliability of the tool, suggesting the need to display internal validity and test-retest reliability with Cronbach's α.

Author's Response: We acknowledged this limitation and provided a detailed response, including information about our pre-testing phase, tool development process, and post-hoc reliability analysis. The statement about this limitation are added in discussion section.

The reviewer asked if the authors displayed crude and adjusted odds ratios in one table for better examination of associations.

Author's Response: We presented crude odds ratios for all variables in Tables 2 and 3, and including only statistically significant predictors in the adjusted odds ratio tables (Tables 4 and 5).

Reviewer #2:

The second reviewer provided the following comments:

The abstract was deemed too long and needed shortening.

Author's Response: We revised and shortened the abstract as recommended.

The reviewer suggested adding background information or research from Thailand to the introduction to establish rationale or knowledge gap.

Author's Response: We incorporated relevant background information and research from Thailand to better establish the rationale and highlight the knowledge gap.

The Methods and Results sections were found to be written in the right direction.

For the Discussion, the reviewer suggested adding limitations and strengths of the study.

Author's Response: We added a section discussing the limitations and strengths of their study, including issues of generalizability, the cross-sectional design, potential biases, and the study's comprehensive examination of multiple factors influencing academic performance.

We would like to express that these changes would significantly improve our manuscript and thanked the reviewers for their insightful reviews.
