“…In the study, we found the percentage of hypertension in the noise exposure group was significantly higher than the control group. This result was in accordance with previous studies [9,[24][25][26][27]. These studies reported that there was a positive relation between hypertension and noise exposure, and some of them analyzed the possible reasons.…”

“…When MetS defined by high triglycerides, BMI and low HDL-C, the occupational noise exposure has a protective effect and can decrease the risk of CHD. While if MetS defined by high blood pressure, BMI and glucose, no protective effect is shown [26], and when noise exposure above 80 dB (A) correlated with hypertension and 4000 HZ has the most enormous effect [9]. All these are the possible reasons for why noise could impact blood pressure of people.…”

For the past few years, noise pollution has been more and more serious, and it may lead to several diseases. While the humans expose to noise in quantity for a long time, their blood pressure will change, and even cause changes in cardiac function. In our study, we attempt to find the relationship between occupational noise and hypertension and impaired hearing, cardiac function. It may be helpful to obtain some useful information on occupational noise exposure of humans. The participants were divided into noisy group ≥90 dB (A) and non-noisy group ≤70 dB (A). We performed this research in an automobile manufacturing company of Chongqing, China during 2011-2012. Our study showed that there may be positive associations between occupational noise and hypertension and impaired hearing, but no conclusion can be drawn between occupational noise and ECG.

“…Furthermore, Li et al also supported our study by concluding that significant effect of noise is related to increased prevalence of MetS [27]. Moreover, An 18-year follow-up study concluded that hypertension and BS, key components of MetS, are the best predictors for assessment of the risk of coronary heart disease due to continuous exposure to occupational noise in support to our study [28].…”

Objective: Noise creates alteration in human health in both physical as well as psychological variations. Effect of noise on components of metabolic syndrome (MetS) has been discussed but not well established. The aim of this study was to investigate the MetS in female workers from textile mill.Methods: A total of 65 female workers were recruited for the study from the high noise (>70 dB) area and low noise (<40 dB) area of a textile mill. Body mass index (BMI), blood pressure (BP), blood sugar (BS), and lipid profile were investigated of the female workers. BP was estimated by auscultatory method. BS was investigated by glucose oxidase-peroxidase (POD) method. Total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were investigated by cholesterol oxidase (CHOD)-POD method, GPO-PAP method, CHOD-POD/phosphotungustate method, and friedewald formula, respectively.Results: Significant outcomes were obtained in this study. BMI was significantly (<0.01) higher in workers working in high noise area compared to low noise (<40 dB) area. Systolic BP and diastolic BP was also significantly (<0.01) higher in high noise area. Fasting BS level was found to be significantly (<0.01) lower in low noise area. In case of lipid profile significant (<0.01) results were obtained except LDL-C. TC and TG were found to be related with noise since their concentration was higher in high noise area compared to low noise area. However, HDL-C was found to be lower in high noise area compared to low noise area. Conclusion:Continuous exposure to occupational noise might be reason for developing cardiovascular disease depending on the degree of MetS in industrial workers. BP and BS seems to be better predictor of MetS in assessing cardiovascular risk.

“…Although this study supports our result that BMI group of overweight is independently associated with prevalence of hypertension. A study done in Finland also suggested that the work load and occupational noise is responsible for the increased risk of coronary heart disease due to increased blood pressure, BMI and glucose level [46]. A multivariate analysis in a study publicized that age, body mass index, cumulative noise exposure, current antihypertensive medication and alcohol intake were the significant predictors for systolic blood pressure [47].…”

“…The exposure to 40-55 dB shows acute rise in adverse health consequences and also the vulnerable groups inclines to be intensely affected. The upsurge of the noise level above 55 dB has recurrent contrary health outcomes with elevated per centum of annoyance in huge population group [46,48]. A cross-sectional study carried out in one of the screw manufacturing factory in Taiwan with 188 male workers showed that the noise exposure of ≥ 80 dB for 2-4 years have a higher risk of hypertension.…”

Background: Noise has been acknowledged as one of the most prevailing physical hazard in occupational health and safety. Noise can possess both permanent and temporary health outcomes. The hazardous exposure to occupational noise is generally identified to have aural effects. However in past few years, researches have been carried out to perceive the association between noise exposure and cardiovascular diseases. Yet, the topic has been under controversies regarding its actual relationship or association since there is an existence of other confounders, variables or lifestyle with the exposure which might affect the subsequent disease condition. The results have not been consistent in the studies. Hypertension is one of the most significant etiological factors for cardiovascular diseases. Noise can cause high blood pressure mostly by two ways: either by releasing stress hormones like steroids or by stimulating sympathetic nervous system. China being one of the most rapidly developing countries in the world is having most prominent effect of noise in the daily life since it is a point for most of the goods manufacturing. Various national and international organizations like CDC, OSHA, and NIOSH etc. has recommended various ways to control the noise hazard and its deleterious impact on human health. This research was also done to assess the relationship or association between noise exposure level and prevalence of hypertension in the workers from steel factory in Guangzhou.

Dual role of physical workload and occupational noise in the association of the metabolic syndrome with risk of coronary heart disease: findings from the Helsinki Heart Study

Abstract: Occupational exposure to workload or noise modifies CHD risk differently depending on which definition of MetS is used. In the presence of physical workload or noise, hypertension and blood glucose were the best predictors.
