Abstract: Objective To investigate the influencing factors of cervical spondylosis risk among civil servants in Yuzhong District of Chongqing,analyze the action path and size of each influencing factor by using structural equation model. Methods The stratified cluster sampling method was used to investigate the risk factors of cervical spondylosis in 342 civil servants in Yuzhong District of Chongqing from October to December 2021. The principal component analysis method was used to extract the relevant potential variables,and the structural equation model was constructed to analyze the influencing factors. Results The total score of cervical spondylosis risk of civil servants in Yuzhong District of Chongqing was （25.32±3.99）points,the fatigue factor score was （8.92±1.86）points,and the behavioral factor score was （16.40±4.49）points. There were statistically significant differences in the scores of fatigue and behavioral factors in the risk of cervical spondylosis among civil servants of different age,working years,having neck pain,neck pain parts,raising their heads and heads high at work,carrying a shoulder bag,low back pain,and tinnitus（all P<0.05）. The direct effect of potential disease factors was 3.412,the direct effect of social characteristic factors was -0.317,and the indirect effect of limb condition factors on civil servants' cervical spondylosis by influencing potential disease factors was 0.088. Conclusion The risk of cervical spondylosis in civil servants in Yuzhong District of Chongqing is at a medium level,the potential disease factors and social characteristics have a direct impact on the risk of cervical spondylosis in civil servants,and the limb status factors affect the risk of cervical spondylosis in civil servants through mediation,which have an indirect impact on the risk of cervical spondylosis in civil servants.
