Association between sedentary behavior, physical activity, and neck pain, disability index, and cervical physiological function in university students: a cross-sectional study


Abstract

Background: With changes in modern lifestyle, cervical health issues among college students have become increasingly prevalent.

Objective: This study aimed to explore the associations between sedentary behavior (SB), physical activity (PA), and neck pain, disability index, and cervical physiological function in university students.

Methods: This cross-sectional study enrolled 126 participants. Self-reported questionnaires were used to assess SB, PA, VAS, and NDI. Objective measurements were taken to evaluate cervical range of motion (ROM), joint position sense (JPS), muscle strength (MS), and muscle endurance (ME). Pearson and Spearman correlations examined the associations between SB, PA, and cervical health indicators. ANOVA and Kruskal-Wallis tests compared differences between groups with varying SB and PA levels.

Results: Correlation analysis revealed significant positive correlations between SB and VAS, as well as JPS (extension JPS-E; right rotation JPS-RRot), and significant negative correlations with cervical ROM (extension ROM-E; left rotation ROM-LRot; right rotation ROM-RRot). Moreover, PA was negatively correlated with NDI and positively correlated with cervical flexor strength (CFS) and extensor strength (CES). Comparative analysis of different levels of SB and PA showed that the High-SB & Low-PA group had significantly worse outcomes in NDI, ROM-RRot, JPS-E, and CES.

Conclusion: SB negatively affects cervical health in university students, whereas moderate PA confers protective benefits. The combined effect of high SB and low PA exacerbates disability index and further deteriorates cervical physiological function. This study provides empirical evidence for preventive and interventional strategies targeting cervical health issues in university students.

Notes for potential reviewers

  • Volunteering is not a guarantee that you will be asked to review. There are many reasons: reviewers must be qualified, there should be no conflicts of interest, a minimum of two reviewers have already accepted an invitation, etc.
  • This is NOT OPEN peer review. The review is single-blind, and all recommendations are sent privately to the Academic Editor handling the manuscript. All reviews are published and reviewers can choose to sign their reviews.
  • What happens after volunteering? It may be a few days before you receive an invitation to review with further instructions. You will need to accept the invitation to then become an official referee for the manuscript. If you do not receive an invitation it is for one of many possible reasons as noted above.

  • PeerJ does not judge submissions based on subjective measures such as novelty, impact or degree of advance. Effectively, reviewers are asked to comment on whether or not the submission is scientifically and technically sound and therefore deserves to join the scientific literature. Our Peer Review criteria can be found on the "Editorial Criteria" page - reviewers are specifically asked to comment on 3 broad areas: "Basic Reporting", "Experimental Design" and "Validity of the Findings".
  • Reviewers are expected to comment in a timely, professional, and constructive manner.
  • Until the article is published, reviewers must regard all information relating to the submission as strictly confidential.
  • When submitting a review, reviewers are given the option to "sign" their review (i.e. to associate their name with their comments). Otherwise, all review comments remain anonymous.
  • All reviews of published articles are published. This includes manuscript files, peer review comments, author rebuttals and revised materials.
  • Each time a decision is made by the Academic Editor, each reviewer will receive a copy of the Decision Letter (which will include the comments of all reviewers).
