The objective of this study was to gain a basic understanding of the influential factors for nonspecific low-back pain (LBP) among adolescents of southern China.
The study was designed as a school-based case control study.
Nonspecific LBP is a common health problem in adolescence. Although some behaviors and socio-demographic factors are believed to contribute to the disorder, influential factors of LBP remain undefined. Moreover, until now there is no available information of influential factors for LBP in Chinese adolescents.
A total of 1,214 adolescents were involved in the study, including 607 cases with nonspecific LBP and 607 controls without history of nonspecific LBP.
A self-administered questionnaire was designed for epidemiological survey to investigate the risk factors for nonspecific LBP. All cases and controls were investigated for their family histories of nonspecific LBP, physical activities, sedentary activities, schoolbag weights, school performances, living conditions, and etc.
A 1:1 matched case-control study was conducted on 1,214 adolescents from an elementary school and a secondary school in Guangzhou City, southern China.
Family history (odds ratio [OR] 2.57, 95% confidence interval [CI] 1.85-3.58), long duration of carrying schoolbag (OR 1.38, 95% CI 1.11-1.72) and rest position between classes (OR 1.18, 95% CI 1.01-1.39) were positively correlated with self-reported nonspecific LBP. Students regularly playing basketball (OR 1.58, 95% CI 1.09-2.30) was found to be significantly more likely to have LBP. Also, students who feel schoolbag uncomfortable (OR 1.38, 95% CI 1.11-1.72) was found to experience more LBP.
Family history, feeling schoolbag uncomfortable, duration of schoolbag carrying, basketball playing and rest position between classes are the major risk factors for nonspecific LBP in adolescents.
本研究旨在了解中国南方青少年非特异性下背痛（LBP）的影响因素。
本研究为基于学校的病例对照研究。
非特异性 LBP 是青少年常见的健康问题。尽管一些行为和社会人口因素被认为与该疾病有关，但 LBP 的影响因素仍不明确。此外，到目前为止，还没有关于中国青少年 LBP 影响因素的可用信息。
共有 1214 名青少年参与了研究，其中 607 例为非特异性 LBP 病例，607 例为无非特异性 LBP 病史的对照。
设计了一份自我管理问卷进行流行病学调查，以调查非特异性 LBP 的危险因素。所有病例和对照均调查了非特异性 LBP 的家族史、体育活动、久坐活动、书包重量、学习成绩、生活条件等。
在中国广州市的一所小学和一所中学对 1214 名青少年进行了 1:1 匹配的病例对照研究。
家族史（比值比[OR]2.57，95%置信区间[CI]1.85-3.58）、书包携带时间长（OR 1.38，95%CI 1.11-1.72）和课间休息姿势（OR 1.18，95%CI 1.01-1.39）与自我报告的非特异性 LBP 呈正相关。经常打篮球的学生（OR 1.58，95%CI 1.09-2.30）患 LBP 的可能性显著增加。此外，感到书包不舒服的学生（OR 1.38，95%CI 1.11-1.72）也会经历更多的 LBP。
家族史、书包不舒服、书包携带时间、打篮球和课间休息姿势是青少年非特异性 LBP 的主要危险因素。
