大棚菜农腰痛危险因素的结构方程模型分析

Structural equation model analysis of risk factors for low back pain among greenhouse vegetable-planting farmers

目的探讨大棚菜农腰痛的危险因素并估计其相对水平。方法采用整群抽样方法，对某大棚种植区的639名大棚菜农进行回顾性问卷调查，并运用smartPLS软件进行腰痛的结构方程模型分析。结果潜变量腰痛的决定系数为0．827，动态负荷、静态负荷、力量施加、人体工效学环境、重复性负荷等潜变量与腰痛的结构系数分别为0．206、0．432、0．266、0．045、0．034，对腰痛的总体影响分别为0．206、0．432、0．266、0．333、0．034。结论大棚菜农腰痛的主要危险因素是静态负荷、人体工效学环境、力量施加和动态负荷。

Objective To explore the risk factors of low back pain （LBP） among greenhouse vegetableplanting farmers and estimate the level of the effects. Methods A serf-made questionnaire based on the Dutch Musculoskeletal Questionnaire and the Nordic Questionnaire was conducted to 639 greenhouse vegetableplanting farmers and then structural equation model was used to analyze the risk factors of LBP in SmartPLS software. Results The coefficient of determination of the model was 0.827, and the structural coefficients of dynamic loads, static loads, force exertion, ergonomie environment and repetitive loads on LBP were 0.21, 0.43, 0.27, 0.045 and 0.034 respectively, and the total effects of the above latent variables on LBP were 0.21, 0.43, 0.27, 0.33 and 0.034 respectively. Conclusion The main risk factors of LBP among greenhouse vegetableplanting farmers were static loads, ergonomic environment, force exertion and dynamic loads.
