Lifestyle Behaviours Profile of Spanish Adolescents Who Actively Commute to School

Round 1

Reviewer 1 Report

Introduction
The authors provide a comprehensive rationale for the manuscript. However, there is no theoretical basis to explain young people's behaviours and especially the transfer of behaviours between similar contexts linked to physical activity (PA) and healthy behaviours.
Another substantial element is the novelty of the study. In this sense, there are similar studies that have analysed the transfer of PA to multiple contexts (e.g., PE <-> PA; PE -> Sport; etc.) and also the relationship between PA and PE with respect to healthy behaviours, for example between PA and healthy eating [1-3] or PE and healthy eating [4-7]. What is different about your study that others have not addressed? Only the relationship between PA behaviour (walking to school) and healthy behaviours?
PE = Physical Education
On the other hand, what are the hypotheses of the study? they should appear right after the main objective.
Discussion
This section should be completely redone. This section should be done in a single body. The contributions made by the authors are scarce (if not non-existent) and a mere extension of the results of the study. In this section, the results achieved in the study should be explained in a reasonable way, based on international literature (e.g. previous theories and studies).

Reviewer 3 Report

The paper is mainly descriptive and focused on its (not fully supported) conclusions, not adequately acknowledging the limitations of the study. The strengths and limitations of the study should be deeply addressed, taking into account sources of potential bias or imprecision: Discuss both direction and magnitude of any potential bias.

The following pertinent reports should be mentioned:

Sedentary patterns and cardiometabolic risk factors in Mexican children and adolescents: analysis of longitudinal data.
