Weight of school material and back pain in students leaving their books at school

Abstract

BACKGROUND AND OBJECTIVES: The prevalence of back pain in children and adolescents has been reason for school health concern. Among different causes, school material weight is highlighted since studies have shown that it exceeds recommended values. So, strategies to decrease material weight have been adopted, such as the availability of cabinets or shelves to leave the books at school. However, it is not well explained whether such strategies would solve the problem. This study aimed at observing the association between school material weight and back pain in students who leave their material at school. METHODS: Sample was made up of 48 students of the 5 th year of Basic Education of a municipal school of Petrolina-PE. Students and their materials were weighed. The back pain and body posture evaluation instrument was used to evaluate back pain. RESULTS: Mean school material weight was 10.8±3.9% of body weight, without difference between genders. From 48 students, 20 have reported back pain and there has been no association between back pain and gender or school material weight. CONCLUSION: Among students, 41.67% have reported back pain, while 52.09% carried weight above 10% of body weight, but there has been no association between school material weight and back pain.

Prevalence and Factors Associated with Musculoskeletal Pain among Secondary School Students

“…It is due to asymmetric load distribution (Yoon, 2014). According to some studies, the way in which the backpack is carried and its model correlate postural risks and BP in adolescents (Candotti et al, 2012;Fernandes et al, 2008;Melo-Marins, 2015).…”

“…The marginal effects in both models support that an increase in the use of backpack is negatively associated with around 12 % more likely not to experience LBP and 5% less likely to sometimes get pain and 6% less likely to always get pain. It may be due to the way and mode in which the backpack is carried (Candotti et al, 2012;Fernandes et al, 2008;Melo-Marins, 2015).…”

“…According to a recent inquiry neck and SP are linked to gender, mainly women (Yeun, 2017). However, another recent investigation indicates no significant difference between males and females (Malik et al, 2017;Melo-Marins et al, 2015). Under the NYCBE curriculum, the introduction of non-core subjects (Table 2) like oral expression may help the pain reporting differences between boys and girls (Rajan & Koti, 2013).…”

“…However, it seems that students are willing to experience this innovation, and they are naïve with respect to many physical discomforts associated with tablet use including MSP in many regions of the body (Calisir & Akdag, 2017;Kim et al 2014;Lee et al, 2018;Uyal et al, 2017). Carrying backpack relative to shoulder bag and handbag is associated with NP and SP asserting other investigations (Dianat et al, 2014;Freedman, 2009) and this may be due to the way and mode in which the backpack is carried (Candotti et al, 2012;Fernandes et al, 2008;Melo-Marins, 2015). Asymmetric load distribution is also responsible for MSP in students (Yoon, 2014).…”

Higiene postural: factores que influyen en una correcta postura en niños y adolescentes. Una revisión sistemática (Postural hygiene: factors that influence correct posture in children and adolescents. A systematic re-view)

“…Esta patología en niños y adolescentes es preocupante para la salud, dado que es determinante en ciertas enfermedades referidas al dolor lumbar en la adolescencia (Melo-Marins et al, 2015). Tanto el dolor de espalda, la postura alterada del hombro, deformidades cervicales y deformidades en la columna, son cambios posturales significativos cuando se tiene una mayor carga en la mochila (Grannemann et al, 2018).…”
