Occupational Noise Exposure and Diabetes Mellitus: A 3-year Retrospective Multicenter Cohort Study

Abstract The global prevalence of diabetes has been increasing. However, occupational environmental factors influencing it have been poorly studied. The effect of occupational noise exposure on diabetes is somewhat controversial. Thus, this study examines the relationship between occupational noise exposure (≥85 dBA) and diabetes incidence. Participants (n = 58,284) were recruited from a Common Data Model cohort of two hospitals from 2013 or 2014 and were annually followed up for three years. Drug history, clinical history of diabetes, and/or fasting glucose of 126 mg/dL or more were defined as new-onset diabetes. Multivariable time-dependent Cox proportional hazard models and Landmark analysis were implemented to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Pooled HRs and 95% CIs were calculated using the weight obtained through standard error. Of the participants, 4.65% developed diabetes during the follow-up. The final adjusted pooled HR of Cox models indicated a significant relationship between occupational noise exposure and increased risk of diabetes (Time-dependent Cox: HR 1.35 [95% CI 1.17–1.57]; Landmark: HR 1.22 [95% CI 1.10–1.35]). There is a significant relationship between occupational noise exposure and incidence of diabetes. Screening for diabetes, active management, and prevention may be necessary to improve the health of individuals exposed to occupational noise.

Exposure Levels

Current legislation and threshold limits for occupational noise exposure may not sufficiently account for higher vulnerability of the foetus. We conducted a systematic literature review and identified 20 relevant studies of prenatal noise exposure levels and health. Maternal tissues attenuate industrial noise by about 30 dB. The foetus responds the earliest to noise exposure from the 19th week of gestational age. There is some evidence of an increased risk of hearing loss at prenatal noise levels≥85 dBA (8 hour average) and little evidence at lower levels. Increased risks for preterm birth, small-for-gestational-age and congenital malformations are seen as single study findings at levels≥90 dBA. There is little evidence for how noise exposure may increase the risk of extra-auditive effects in the foetus. Methodological shortcomings and the scarce number of studies limit the conclusions that can be drawn. Still, we recommend pregnant women avoid working at noise levels≥85 dBA.

Cox Proportional Hazard Models

The role of hazardous occupational noise exposure on the development of prediabetes is not well researched. We aimed to elucidate exposure to hazardous occupational noise as an independent risk factor for high fasting blood glucose (FBG). Participants exposed/non-exposed to occupational noise were recruited from the Common Data Model cohorts of 2013/2014 from two centers and were followed-up for 3 years. Multivariate time-dependent Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) and were adjusted for various covariates. Pooled HRs were calculated. Among the 43,858 participants of this retrospective cohort study, 37.64% developed high FBG. The mean (standard deviation) age in the cohort was 40.91 (9.71) years. In the fully adjusted models, the HRs of high FBG in the two centers were 1.35 (95% CI: 1.24–1.48) and 1.22 (95% CI: 1.17–1.28), and the pooled HR was 1.28 (95% CI: 1.16–1.41). A Kaplan–Meier plot of high FBG incidence by occupational noise exposure showed significant results (p < 0.001). We found that occupational noise exposure is significantly associated with high FBG. Preventing exposure to hazardous noise in the work environment may help reduce the risk for prediabetes among workers.

Hearing thresholds and distortion product otoacoustic emissions were measured for teachers of vocal performance who were gathered for a national conference. Results showed mean audiometric thresholds to be consistent with noise induced hearing loss, more than what would be expected with normal aging. Years of instruction and age were considered as factors in the hearing loss observed. It was concluded that hearing conservation should be initiated with this group to help raise awareness and protect them from hearing loss due to occupational noise exposure.
