Abstract
This study was conducted to estimate the current prevalence of hypertension, cardiovascular condition and hearing difficulty of workers exposure to occupational noise, and to analyze any associations between these abnormal signs and occupational noise exposure. The subjects included 5205 noise-exposed workers. Workers with high noise exposure were more likely to have a higher threshold value than low exposure ones (P < 0.05). Subjects in the high exposure group had a significantly higher risk of hypertension and hearing loss than the ones in low exposure group. Between the ages of 30 and 45, high-level occupational noise exposure led to a significantly raising risk of both hypertension (Adjusted OR = 1.59, 95% CI, 1.19–2.11) and hearing loss (Adjusted OR = 1.28, 95% CI, 1.03–1.60) when comparing to low-level noise exposure. In male workers, the prevalence of hearing difficulty in high exposure group was approximately 1.2 times worse than in low group (P = 0.006). In addition, exposure to high noise level demonstrated a significant association with hypertension and hearing loss when the duration time to occupational noise was longer than 10 years. Hypertension and hearing difficulty is more prevalent in the noise-exposed group (higher than 85 dB[A]). Steps to reduce workplace noise levels and to improve workplace-based health are thus urgently needed.
Highlights
In order to observe whether there is in an association between noise exposure and abnormal health effects such as hypertension, cardiovascular condition or hearing loss, we undertook this study and analyzed data from occupational, physical examinations performed in the Nanjing Prevention and Treatment Center for Occupational Diseases from 2016 to 2017
In order to examine the association between occupational noise exposure and health condition, we divided the participants into a high exposure group and a low exposure group and selected 85 dB(A) as the cut-off value for the different noise-exposure groups
This study reported the prevalence of hypertension, abnormal ECG, and abnormal hearing thresholds in workers exposed to occupational noise in Nanjing city
Summary
In order to observe whether there is in an association between noise exposure and abnormal health effects such as hypertension, cardiovascular condition or hearing loss, we undertook this study and analyzed data from occupational, physical examinations performed in the Nanjing Prevention and Treatment Center for Occupational Diseases from 2016 to 2017. Physical examination data, the purposes of this study were the following: (1) estimate the current prevalence of hypertension, cardiovascular condition, and hearing difficulty with workers who have been exposed themselves to occupational noise for many years; (2) examine any link these outcomes may have to occupational noise exposure
