Study on relationship between blood sugar level and occupational noise-induced hearing loss in male noise-exposed workers
Objective To explore the relationship between the blood sugar level of male workers exposed to noise and oc-cupational noise-induced hearing loss(NIHL).Methods The physical examination data of on-the-job workers in an automobile manufacturing enterprise were collected,and the male noise workers with working experience of more than one year were taken as the research objects.The research objects were divided into normal hearing group,hearing loss group,high-frequency hearing loss group and high-frequency hearing loss group.logistic regression model was used to analyze the influencing factors of NIHL and the relationship between hyperglycemia and NIHL.Results Among 2735 workers exposed to noise,993(36.3％)suffered from hearing loss,including 929(34.0％)with high frequency hear-ing loss and 64(2.3％)with high frequency hearing loss.With the increase of age,the detection rates of hearing loss,high-frequency hearing loss and high-frequency companion frequency hearing loss of noise-exposed workers all showed an upward trend(x2trends=146.563,120.397,49.340,P＜0.05);With the increase of working years,the de-tection rate of hearing loss and high-frequency hearing loss of workers exposed to noise showed an upward trend(xtrends=57.447,60.167,P＜0.05).Drinking alcohol is a risk fac-tor for hearing loss and high-frequency hearing loss in noise-exposed workers(P＜0.05).The detection rates of hearing loss,high-frequency hearing loss and high-frequency hearing loss associated with speech frequency in noise-exposed workers in hyperglycemia group were higher than those in normal blood sugar group(P＜0.05).After adjusting the factors that may affect hearing loss(age,length of service,drinking and hypertension),hyperglycemia is still a risk factor for hearing loss(P＜0.05).Conclusion Hyperglycemia may aggravate the risk of NIHL among noise workers.
