Survey on occupational injury among workers in a steel enterprise / 预防医学

ABSTRACT

Objective @#To investigate the prevalence of occupational injury and identify its influencing factors among workers in a steel enterprise in Gansu Province, so as to provide insights into prevention of occupational injury among steel workers. @*Methods@#Workers were sampled from a steel enterprise in Gansu Province using a cluster sampling method from January to March 2022, and participants' demographics, occupational history and occupational injury were collected using questionnaire surveys. The type of job and site and type of injury were analyzed among workers with occupational injuries, and factors affecting workers' occupational injuries were identified using a multivariable logistic regression model. @*Results@#A total of 12 089 questionnaires were allocated and 10 725 valid questionnaires were recovered, with an effective recovery rate of 88.71%. The respondents included 9 412 males (87.77%) and 1 312 females (12.23%), and had a median age of 36.00 (interquartile range, 15.00) years. Junior college and above was the predominant educational level (6 056 workers, 56.47%), and the respondents had a median length of service of 10 (interquartile range, 11) years. The prevalence of occupational injury was 5.25% among respondents. Overhaul worker was the main type of job (11.90%), and object strike was the predominant type of occupational injury (18.25%), while the lower limb was the predominant site of injury (27.82%). Multivariable logistic regression analysis identified men (OR=2.464, 95%CI 1.580-3.843), age (30 to 39 years, OR=2.561, 95%CI 1.643-3.993; 40 to 49 years, OR=5.197, 95%CI 2.679-10.079; 50 years and older, OR=10.620, 95%CI 6.788-16.615), exposure to high temperature (OR=1.400, 95%CI 1.165-1.683), operating equipment failure (OR=1.291, 95%CI 1.048-1.591), absence of personal safety protection equipment (OR=1.555, 95%CI 1.064-2.273) and safety behavior scores (OR=0.967, 95%CI 0.937-0.996) as factors affecting occupational injuries among workers in a steel enterprise. @*Conclusions@#Men and overhaul workers are at a high risk of occupational injuries in this steel enterprise. Objectstrike is the predominant type of injury and lower limb is the main site of injury. The risk of occupational injuries is affected by gender, age, working environments, equipment status and safety behaviors.
