“…Results of such studies are mixed. For blood pressure, while Lee et al (2010) found no changes across noise exposed groups, Lusk et al (2004) and Zamanian et al (2013) observed increased blood pressure with noise exposure. Likewise, Bjor et al (2007) found no changes in HRV between noise exposure groups; however, both Lee et al (2010) and Kraus et al (2013) found significant changes in HRV in groups exposed to higher noise intensities.…”

Background While previous epidemiological studies report adverse effects of long-term noise exposure on cardiovascular health, the mechanisms responsible for these effects are unclear. We sought to elucidate the cardiovascular and stress response to short-term, low (31.5-125 Hz) and high (500 – 2000 Hz) frequency noise exposures. Methods Healthy male (n = 10) participants were monitored on multiple visits during no noise, low- or high-frequency noise exposure scenarios lasting 40 minutes. Participants were fitted with an ambulatory electrocardiogram (ECG) and blood pressure measures and saliva samples were taken before, during and after noise exposures. ECGs were processed for measures of heart rate variability (HRV): high-frequency power (HF), low-frequency power (LF), the root of the mean squared difference between adjacent normal heart beats (N-N) intervals (RMSSD), and the standard deviation of N-N intervals (SDNN). Systolic blood pressure (SBP), diastolic blood pressure (DPB), and pulse were reported and saliva was analyzed for salivary cortisol and amylase. Multivariate mixed-effects linear regression models adjusted for age were used to identify statistically significant difference in outcomes by no noise, during noise or after noise exposure periods and whether this differed by noise frequency. Results A total of 658, 205, and 122, HRV, saliva,and blood pressure measurements were performed over 41 person days. Reductions in HRV (LF and RMSSD) were observed during noise exposure (a reduction of 19%(−35,−3.5) and 9.1%(−17,−1.1), respectively). After adjusting for noise frequency, during low frequency noise exposure, HF, LF, and SDNN were reduced (a reduction of 32%(−57,−6.2), 34%(−52,−15), and 16%(−26,−6.1), respectively and during high frequency noise exposure, a 21%(−39,−2.3) reduction in LF, as compared to during no noise exposure was found. No significant (p>0.05) changes in blood pressure,salivary cortisol or amylase were observed. Conclusions These results suggest that exposure to noise, and in particular, to low-frequency noise negatively impacts HRV. The frequencies of noise should be considered when evaluating the cardiovascular health impacts of exposure.

“…Similarly, according to research by Zamanian et al 23 which examined the effect of steel industry noise exposure with the intensity of 85, 95, and 105 dBA for 5 minutes to blood pressure and heart rate in 50 industrial workers in Iran. The results showed that with 5 min exposure there was an increase in blood pressure however it was statistically insignificant.…”

“…The results showed that with 5 min exposure there was an increase in blood pressure however it was statistically insignificant. 23 Kalantary et al 12 stated that significant differences in blood pressure (systolic and diastolic) between the unexposed groups (exposure to 53 dBA noise) and exposed group (exposed to noise 85-108 dBA occurred. The results of this study are also in line with the research of Chen et al 24 which stated exposure to the noise intensity of 87.5 dB (A), the duration of noise exposure of 4.21 years and a CNE of 92.28% increased systolic and diastolic blood pressure of labors.…”

Noise exposure is often found in the industrial environment that exposed workers at risk for increasing blood pressure. This study aimed at investigating the association between noise level, duration of noise exposure, age, use of earplugs, and body mass index with blood pressure on textile industry workers. An observational study with the cross-sectional design conducted during August to October 2016. The study population was 180 textile industry workers in Surakarta selected by consecutive sampling method. Statistical analysis used was multiple logistic regression. Results showed that variables associated with systolic blood pressure were the use of earplugs (OR=12.7), noise level (OR=7.2), body mass index (OR=5.3), age (OR=4.4) and duration of noise exposure (OR=3.5). Variables associated with diastolic blood pressure were the use of earplugs (OR=6.9), age (OR=6.6), noise level (OR=6.1), body mass index (OR=4.4), and duration of noise exposure (OR=3.1). In clonclusion, the risk factors for blood pressure increased among industrial workers are the use of earplug, noise level, body mass index, age and duration of noise exposure. Key words: Blood pressure, textile industry workers Asosiasi antara Faktor Risiko dan Tekanan Darah pada Pekerja Industri Tekstil AbstrakPaparan kebisingan yang mengekspos pekerja sering ditemukan di lingkungan industri sehingga berisiko terjadi peningkatan tekanan darah. Penelitian ini bertujuan mengetahui hubungan tingkat kebisingan, durasi paparan kebisingan, usia, penggunaan sumbat telinga, dan indeks massa tubuh dengan tekanan darah pada pekerja industri tekstil. Penelitian ini menggunakan jenis observasional dengan desain cross-sectional yang dilakukan pada bulan Agustus-Oktober 2016. Populasi penelitian adalah pekerja industri tekstil di Surakarta. Terpilih 180 orang pekerja dengan menggunakan metode sampling konsekutif. Analisis statistik yang digunakan adalah regresi logistik berganda. Variabel yang berhubungan dengan tekanan darah sistole adalah penggunaan sumbat telinga (OR=12,7), tingkat kebisingan (OR=7,2), indeks massa tubuh (OR=5,3), usia (OR=4,4), dan durasi paparan kebisingan (OR=3,5). Variabel yang terkait dengan tekanan darah diastole adalah penggunaan sumbat telinga (OR=6,9), usia (OR=6,6), tingkat kebisingan (OR=6,1), indeks massa tubuh (OR=4,4), dan durasi paparan kebisingan (OR=3,1). Simpulan, faktor risiko peningkatan tekanan darah di kalangan pekerja industri tekstil adalah penggunaan sumbat telinga, tingkat kebisingan, indeks massa tubuh, usia, dan durasi paparan kebisingan.

“…Em vigência de exposição ao ruído, verificou-se aumento da pressão arterial sistólica em trabalhadores de uma empresa siderúrgica em Fars, Irã. Contudo, não se confirmou resultado significativo (p > 0,05) quando os índices pressóricos foram comparados com a situação anterior à exposição 27 . Em um estudo transversal que focalizou amostra probabilística de 4.300 motoristas rodoviários da cidade de Isfahan, Irã, a pressão arterial não apresentou significância estatística com a perda auditiva induzida por ruído 21 .…”

Objetivou-se verificar a associação entre o diagnóstico de perda auditiva autorrelatado por trabalhadores do transporte urbano da Região Metropolitana de Belo Horizonte, Minas Gerais, Brasil, e fatores individuais e ocupacionais. O tamanho da amostra foi calculado por quotas e estratificado por ocupação (motoristas e cobradores) nas empresas de Belo Horizonte, Betim e Contagem. A coleta de dados foi realizada face a face com o auxílio de netbooks pelos entrevistadores. A variável resposta foi definida pela resposta positiva à pergunta sobre a vigência de diagnóstico médico de perda auditiva. As variáveis independentes foram organizadas em 3 blocos: características sociodemográficas, estilo de vida e aspectos do trabalho. O diagnóstico de perda auditiva foi mencionado por 213 dos 1.527 trabalhadores e esteve associado à idade e ao diagnóstico de zumbido. Na esfera ocupacional, destacaram-se o absenteísmo-doença, antiguidade no cargo e dois riscos ambientais: ruído insuportável e vibração de corpo inteiro. Medidas de prevenção da perda auditiva para os trabalhadores do transporte urbano são necessárias.
