Prevalence and influencing factors of work-related knee pain among workers in shoemaking industry
摘要
Abstract
[Background]Shoemaking industry workers are prone to work-related musculoskeletal disorders(WMSDs)due to long-term awkward postures during the work process.There is little research on the prevalence and influencing factors of WMSDs in the knee region of this industry,and it should be taken seriously. [Objective]To estimate the prevalence of work-related knee pain among shoemaking workers and analyze the related influencing fac-tors. [Methods]A total of 6982 shoemaking workers were selected from 26 shoemaking factories in Guangdong,Hubei,Fujian,Chongqing,Shandong,Zhejiang,and Jingxi by convenience sampling.Prevalence of work-related knee pain in past year,demographic characteristics,occupational related factors,and work posture were collected by a cross-sectional survey using the electronic version of Musculoskeletal Disorder Questionnaire.Logistic regression analysis was used to analyze the influencing factors that may lead to work-related knee pain. [Results]This survey collected 6982 valid questionnaires with a recovery rate of 98.3%.The prevalence of work-related knee pain of shoemaking workers in the past 12 months was 13.0%(908/6982).According to the results of logistic regression analysis,compared with workers with less than 5 years of service,workers with 5-10 years of service(OR=1.21,95%CI:1.02,1.45)and more than 10 years(1.53,95%CI:1.27,1.83)showed a higher risk of knee WMSDs;sometimes,often and very frequent(reference:rarely or never)long-term standing(OR=1.33,95%CI:1.08,1.64;OR=2.67,95%CI:2.10,3.39;OR=2.75,95%CI:2.08,3.63)and sometimes,often and very frequent(reference:rarely or never)long-term squatting or kneeling(OR=1.80,95%CI:1.47,2.21;OR=2.43,95%CI:1.58,3.75;OR=3.22,95%CI:1.66,6.24)increased the risk of knee pain:long-term bending(OR=1.59,95%CI:1.34,1.89)and often repeated movement of lower limbs and ankles(OR=1.48,95%CI:1.25,1.75)were also risk factors for knee WMSDs among shoemaking industry workers(P<0.05).Adequate rest time(OR=0.58,95%CI:0.49,0.68)and able to stretch or change leg posture(OR=0.75,95%CI:0.64,0.88)reduced the risk of knee WMSDs(P<0.05). [Conclusion]In the shoemaking industry,length of service and awkward postures are risk factors for knee pain.The shoemaking enterprises should ensure that workers have sufficient rest time,reduce long-term standing,squatting,kneeling,and bending postures,as well as lower limbs repetition in order to reduce the occurrence of knee WMSDs of workers.关键词
