| Abstract Introduction: Continuous use of backpacks during elementary school, especially when the weight and duration are not proportional, can significantly affect posture and spinal curvature, including the lumbar lordosis angle. The aim of this review study was to examine recent research findings on the relationship between backpack weight and duration of carrying with changes in lumbar lordosis among elementary school students. Methods: This study was conducted as a systematic review. Articles were searched in national and international scientific databases including Google Scholar, PubMed, SID, and Scopus within the time frame of 2006 to 2024. The keywords used were “backpack,” “lumbar lordosis,” “students,” and “posture.” After removing duplicate and irrelevant studies, 15 articles that met the inclusion criteria were selected and analyzed. Data were analyzed using content review and comparison of key findings across studies. Results: The results of the reviewed studies indicate that increasing backpack weight (more than 10–15% of body weight) and prolonged carrying can lead to changes in the lumbar lordosis angle, increased pressure on the lumbar vertebrae, and postural misalignment among students. Moreover, the design of the backpack, its placement on the body, and the duration of carrying were identified as influential factors in the development of spinal deformities. Conclusion: The findings of this review suggest that maintaining a standard backpack weight, proper carrying techniques, and ergonomic backpack design play important roles in preventing musculoskeletal disorders. It is recommended that educational programs be implemented for parents, teachers, and students to raise awareness of this issue. |
