There is a lack of studies that analyze the interaction between risk variables as predictors of back pain (BP) in adolescents. The objectives of this study were to examine the relationship between BP and several risk variables, and to analyze the effect of the mediation of gender in this association. This cross-sectional study included = 617 adolescents (mean age: 14.10 ± 1.18 years old) who completed the BP Adolescent Survey and who performed the bench trunk curl (BTC) and Sorensen (SOR) tests. Males showed a significantly lower prevalence (OR: 0.67) and frequency (contingency coefficient: 1.73) of BP than females, less participation in leisure-time sedentary behaviors (LRSBs) per day of more than 2 h (Cramer's V: 0.110), a higher sufficient Physical Activity (PA) (Cramer's V: 0.323) and a higher score in the BTC test (Contingency coefficient: 0.346). A high BTC score indicated significantly lower risk of BP than mid (OR: 1.74; = 0.025) or low (OR: 1.62; = 0.022) BTC. The mediation analysis showed a significant indirect effect with a significant value for the Sobel test (z = 7.45 ± 0.111). When the BTC test value was included in the equations, the connection between gender and BP was no longer significant. There was a difference in the prevalence between gender in BP and LRSB and PA. BP was associated with the SOR test. The association between BP and gender was mediated by SOR results.
缺乏对作为青少年背痛（BP）预测因素的风险变量之间相互作用进行分析的研究。本研究的目的是检验BP与多个风险变量之间的关系，并分析性别在这种关联中的中介作用。这项横断面研究纳入了617名青少年（平均年龄：14.10±1.18岁），他们完成了青少年BP调查，并进行了仰卧起坐（BTC）和索伦森（SOR）测试。男性的BP患病率（OR：0.67）和发作频率（列联系数：1.73）显著低于女性，每天参与超过2小时休闲久坐行为（LRSB）的情况较少（克莱姆V系数：0.110），有更充足的身体活动（PA）（克莱姆V系数：0.323），并且在BTC测试中的得分更高（列联系数：0.346）。较高的BTC得分表明BP风险显著低于中等（OR：1.74；P = 0.025）或较低（OR：1.62；P = 0.022）的BTC。中介分析显示存在显著的间接效应，索贝尔检验具有显著值（z = 7.45±0.111）。当将BTC测试值纳入方程时，性别与BP之间的联系不再显著。BP、LRSB和PA在性别患病率上存在差异。BP与SOR测试相关。BP与性别之间的关联由SOR结果介导。
