Occupational noise exposure and risk of hypertension in an industrial workforce

Abstract

Background Community noise exposure has been shown to increase the risk of hypertension; however, the relationship between occupational noise exposure and hypertension is less clear. Methods Using an inception cohort of workers in a specialty metals manufacturing company, we retrospectively assessed occupational noise exposure, hearing acuity, and incident hypertension diagnoses using administrative datasets. Time-weighted average noise exposure levels were assigned to employees based on their job histories. Cox proportional hazards models were performed to determine the association of noise exposure with risk of incident hypertension. Results The adjusted hazard ratio (HR) of incident hypertension did not significantly differ between groups by cumulative continuous or categorized noise exposure metric. Conclusion We found no increased risk of incident hypertension with exposure to occupational noise among workers. Further assessment examining workers’ use of hearing protection devices is warranted.

Hearing Loss Characteristics of Workers with Hypertension Exposed to Occupational Noise: A Cross-Sectional Study of 270,033 Participants

“…Noise is the most important environmental factor and the most frequent occupational hazard, predominantly found among industrial workers [3]. According to information originating from the American Speech Language Hearing Association (ASHA) [4], 28 million persons in the US have various kinds of HL, of whom 80% cannot be reversed.…”

Paraoxonase 3 gene polymorphisms are associated with occupational noise-induced deafness: A matched case-control study from China

“…Noise is the most important environmental factor that may be detrimental to health [ 1 , 2 ], especially for hearing loss [ 3 ]. Occupational noise is the most frequent occupational hazard, and the rate of disability-adjusted life years attributed to this form of noise has steadily increased worldwide from 1990 (61.11 /100 thousand) to 2017 (78.21/100 thousand) [ 4 ].…”

Noise-induced hearing loss (NIHL) is a sensorineural hearing deficit that begins with chronic exposure to the higher frequencies (3 to 6 kHz) and is the primary occupational disease predominantly found among industrial workers [ 1 ].…”

Analysis and application of a new noise test system for the hydraulic motor

“…The emergence of high-pressure pumps and high-torque hydraulic motors has made the vibration and noise problems of hydraulic systems more and more serious, which seriously restricts the development of hydraulic technology (Ding et al, 2018). Noise not only deteriorates the environment, but also affects the health of the operator and damages hydraulic components (Liu et al, 2010;Tessier-Sherman et al, 2017;Zhang et al, 2019).…”
