This study aimed to examine the effect of the interaction between gender-specific occupational physical activity (OPA) and leisure-time physical activity (LTPA) on low back pain (LBP) risk.
Data were obtained from a large-scale cohort survey of Koreans, comprising a total of 2750 participants recruited during 2011-2012. OPA and LTPA were assessed using validated questionnaires and classified into two groups: "< 150 min/wk" and "≥ 150 min/wk." LBP was defined based on the Oswestry Disability Index (ODI) and visual analogue scale (VAS) criteria. Multiple logistic regression analyses were performed to calculate odds ratios (OR) with 95% confidence intervals (CI), and multiple linear regression analyses were used to estimate β coefficients with 95% CI to assess the associations between OPA, LTPA, and LBP.
The results showed that increased OPA was significantly associated with higher ODI scores (β = 0.02, p = 0.021), whereas increased LTPA was significantly associated with reductions in both ODI (β = -0.07, p = 0.012) and VAS scores (β = -0.01, p = 0.013). Furthermore, engaging in OPA for ≥ 150 min/week was associated with an elevated LBP risk (OR = 1.38, 95% CI = 1.12-1.69), with significant gender differences observed. In contrast, for participants with < 150 min/wk of leisure-related physical activity, LBP risk increased (OR = 1.22, 95% CI = 1.01-1.76), whereas for those with ≥ 150 min/wk, LBP risk decreased (OR = 0.84, 95% CI = 0.66-0.95), a significant effect observed only in females.
These findings suggest that ensuring adequate rest during OPA and promoting leisure-related physical activity may be critical strategies for reducing chronic LBP.
本研究旨在探讨特定性别职业体力活动（OPA）与休闲时间体力活动（LTPA）之间的相互作用对腰痛（LBP）风险的影响。
数据来自一项针对韩国人的大规模队列调查，共纳入2011 - 2012年招募的2750名参与者。使用经过验证的问卷评估OPA和LTPA，并将其分为两组：“<150分钟/周”和“≥150分钟/周”。根据奥斯威斯利残疾指数（ODI）和视觉模拟量表（VAS）标准定义LBP。进行多因素逻辑回归分析以计算比值比（OR）及其95%置信区间（CI），并使用多因素线性回归分析估计β系数及其95%CI，以评估OPA、LTPA与LBP之间的关联。
结果显示，OPA增加与较高的ODI评分显著相关（β = 0.02，p = 0.021），而LTPA增加与ODI（β = -0.07，p = 0.012）和VAS评分降低（β = -0.01，p = 0.013）均显著相关。此外，每周进行OPA≥150分钟与LBP风险升高相关（OR = 1.38，95%CI = 1.12 - 1.69），观察到显著的性别差异。相比之下，对于休闲相关体力活动<150分钟/周的参与者，LBP风险增加（OR = 1.22，95%CI = 1.01 - 1.76），而对于≥150分钟/周的参与者，LBP风险降低（OR = 0.84，95%CI = 0.66 - 0.95），仅在女性中观察到显著影响。
这些发现表明，在OPA期间确保充足休息并促进休闲相关体力活动可能是降低慢性LBP的关键策略。
