生产性粉尘与噪声暴露对汽车制造业工人高血糖的影响OA

[Background]Both productive dust and noise are occupational hazards,and each can induce changes in blood glucose levels among workers. [Objective]To explore the potential interactive effects of exposure to productive dust and noise on the risk of hyperglycemia among automobile manufacturing workers. [Methods]Using a cluster sampling method,workers undergoing occupational health examination from three automobile manufacturing plants in Wuhan in 2022 were selected.Basic information was collected using a questionnaire designed by the Chinese Center for Disease Control and Pre-vention.Exposure history was obtained through occupational history interviews.Clinic indicators such as blood pressure,blood lipids,fasting blood glucose(FBG),and fatty liver status,were re-trieved from examination records.Hyperglycemia was defined as FBG>6.1 mmol·L-1.Logistic re-gression models analyzed the independent effects of occupational noise and dust exposure,while additive and multiplicative interaction models assessed their interactive effects on hyper-glycemia. [Results]The prevalence of hyperglycemia among the 1 223 participants was 7.7%.Logistic re-gression showed that using workers without exposure as reference,the odds ratios(OR)and 95%confidence intervals(CI)for hyperglycemia among workers exposed only to dust,only to noise,and to both were 2.15(1.90,4.23),2.23(1.40,5.08),and 3.75(1.95,7.24),respectively.A linear association was observed between the duration of noise exposure and blood glucose levels(P<0.05).Interaction analysis showed no multiplicative interaction or additive interaction. [Conclusion]Exposure to productive dust and noise are independent risk factors for hyperglycemia among workers.While both contribute to increased risk,no significant synergistic interaction is observed.
