Investigation of neck and shoulder pain among workers in an automobile plant / 中华劳动卫生职业病杂志

ABSTRACT

Objective@#To investigate the prevalence and risk factors of neck and shoulder pain (NSP) among automobile manufacturing workers and to provide a theoretical basis for prevention of NSP.@*Methods@#From November 5 to November 19, 2017, a total 446 works who had worked for more than one year were recruited from an automobile plant by cluster sampling method. Chi square test and unconditional logistic regression were used to exam the relation between influencing factors and NSP.@*Results@#The annual prevalence rate of NSP was 34.8%. Multifactor regression analysis showed that age、work fatigue、department staff shortages、lifting heavy objects in awkward positions、neck flexion foreword and prolong sitting position work were the risk factors of NSP (OR=2.18, 95%CI1.49~3.18; OR=4.52, 95%CI1.27~16.00; OR=1.66, 95%CI1.04~26.68; OR=2.10, 95%CI1.16~3.81; OR=2.25, 95%CI1.39~3.66; OR=2.42, 95%CI1.06~5.56) and work break was the benefit factors of NSP (OR=0.58, 95%CI0.36~0.94) .@*Conclusion@#The annual prevalence rate of NSP among automobile manufacturing workers was high. Lifing heavy objects、awkward working positions and unreasonable work arrangement were the major risk factors of NSP, and work break can effectively reduce the risk of NSP. Effective ergonomic intervention should be carried out to prevent the occurrence of NSP.
