Carrying a schoolbag is a daily activity for most children and adolescents.The perception of a schoolbag's weight depends upon the individual and is a relevant theme in schoolchildren. Describing the association between the perception of heaviness in carrying a schoolbag and NLBP can facilitate the planning of preventive programs, quite different from those based on specific weight limits for schoolbags in children and youth.
To determine the prevalence of non-specific low back pain (NLBP) and to analyse the association between the perception of heaviness in carrying of schoolbags and NLBP in Polish children and youth aged 10-19.
This study included 11,423 children and youth (6,252 girls and 5,171 boys) from Poland. An original questionnaire was used to assess NLBP prevalence.
Among 11,423 of the respondents, 41.5% of the respondents admitted that they had experienced NLBP in the period of the last 12 months. The percentage of individuals reporting NLBP increased with age of participants, < 0.001. Girls reported NLBP more often than boys ( < 0.001). Students with NLBP declared that their school backpack was heavy more often than students without LBP. Students who thought that their backpacks weighed too much manifested a 1.44 (95% Cl [1.33-1.55]) times higher probability to experience NLBP.
In the examined group of schoolchildren a frequent occurrence of NLBP (41.5%) was noted. Its occurrence was related to female sex and age. Students who thought that their backpacks weighed too much manifested higher probability to develop NLBP.
对于大多数儿童和青少年来说，背书包是一项日常活动。对书包重量的感知因人而异，是学童中的一个相关主题。描述背书包时的沉重感与非特异性腰痛（NLBP）之间的关联有助于预防计划的制定，这与基于儿童和青少年书包特定重量限制的计划有很大不同。
确定波兰10至19岁儿童和青少年中非特异性腰痛（NLBP）的患病率，并分析背书包时的沉重感与NLBP之间的关联。
本研究纳入了来自波兰的11423名儿童和青少年（6252名女孩和5171名男孩）。使用一份原创问卷来评估NLBP患病率。
在11423名受访者中，41.5%的受访者承认在过去12个月内经历过NLBP。报告NLBP的个体百分比随参与者年龄增加而增加，P<0.001。女孩报告NLBP的频率高于男孩（P<0.001）。患有NLBP的学生宣称他们的书包比没有腰痛的学生更常被认为很重。认为自己书包太重的学生出现NLBP的概率高出1.44倍（95%CI[1.33 - 1.55]）。
在所检查的学童组中，NLBP的发生率较高（41.5%）。其发生与性别和年龄有关。认为自己书包太重的学生发生NLBP的概率更高。
