Abstract:
Objective To investigate the factors influencing the electrocardiogram results in the workers exposed to noise in steel-making and steel rolling workshops of an iron and steel plant.Methods From September to December,2013,cluster sampling was used to select 3 150 workers exposed to noise in the steel-making and steel-rolling workshops of an iron and steel plant,and a questionnaire survey and physical examinations were performed.The number of valid workers was 2 915,consisting of 1 606 workers in the steel-rolling workshop and 1 309 in the steel-making workshop.The electrocardiogram results of the workers in steel-making and steel-rolling workshops were analyzed.Results The overall abnormal rate of electrocardiogram was 26.35％,and the workers in the steel-making workshop had a significantly higher abnormal rate of electrocardiogram than those in the steel-rolling workshop (32.24％ vs 21.54％,P＜0.05).Male workers had a significantly higher abnormal rate of electrocardiogram than female workers (27.59％ vs 18.61％,P＜0.05).The workers with a drinking habit had a significantly higher abnormal rate of electrocardiogram than those who did not drink (28.17％ vs 23.75％,P＜0.05).The workers exposed to high temperature had a significantly higher abnormal rate of electrocardiogram than those who were not exposed to high temperature (29.43％ vs 20.14％,P＜ 0.05).The abnormal rates of electrocardiogram in the workers with cumulative noise exposure levels of ＜90,90～ 94,95～99,100～104,and 105～113 Db (A)·year were 21.21％,21.76％,26.50％,27.27％,and 32.16％,respectively,with significant differences between any two groups (P＜0.05).The multivariate logistic regression analysis showed that a cumulative noise exposure of 105-113 Db (A) ·year (OR =1.36,95％ CI:1.03～1.80),a drinking habit(OR=1.20,95％ CI:1.01～1.43),and high temperature(OR=1.60,95％ CI:1.32～1.92) were the risk factors for abnormal electrocardiogram results.Conclusion High cumulative noise exposure,alcohol consumption,and high temperature may affect the abnormal rate of electrocardiogram in the workers exposed to noise in steel-making and steel-rolling workshops.
