“…A conveniência de uma amostra impossibilita fazer uso da inferência estatística dos resultados, já que ela não foi obtida atendendo aos pressupostos da estatística inferencial. Da mesma forma, em caso de estudos que abordam o universo de indivíduos (um censo) [5][6]10,12,25 não há porque se fazer testes estatísticos, tendo em vista que os resultados foram obtidos para todos os indivíduos da população e, portanto, não foi retirada uma porção de um universo para o qual pretende-se inferir estatisticamente os resultados obtidos na amostra.…”

“…Todos os oito estudos [5][6][7][8][9][10][11][12] retidos sobre ruído e hipertensão demonstraram alguma associação positiva, inclusive aqueles que foram analisados em combinação com outros fatores de risco ocupacionais (trabalho em turnos e solventes) 5,8,11 . No entanto, os resultados encontrados são variáveis com relação aos seguintes aspectos: medida de frequências de ruído, nível em decibéis e alteração de pressão sistólica e/ou diastólica.…”

Fonte de financiamento: nenhuma REVISÃO DE LITERATURA RESUMO | Contexto: A hipertensão arterial sistêmica (HAS) constitui um dos principais problemas de saúde pública da atualidade. Sabe-se que a etiologia da HAS é multifatorial. Com relação aos fatores associados ao desenvolvimento dessa patologia, tem-se discutido na literatura a exposição a fatores ocupacionais como um risco independente para o desenvolvimento de hipertensão. Objetivos: Este estudo teve por objetivo realizar uma revisão de literatura sobre fatores ocupacionais e hipertensão arterial sistê-mica. Métodos: Uma consulta de artigos selecionados publicados num período de cinco anos (2008-2012) nas principais bases de dados eletrônicas: SciELO, MEDLINE e LILACS. Resultados: Dentre os fatores ocupacionais analisados, o ruído se destacou como possivelmente associado à hipertensão arterial, seguido de trabalho em turnos. Conclusão: Apesar de os resultados apontarem ruído e trabalho em turnos como fatores possivelmente associados à hipertensão arterial, são necessários mais estudos sobre o tema -HAS e fatores ocupacionais -para ampliar a compreensão dessa problemática. Palavras-chave | hipertensão; saúde do trabalhador; fatores de risco. ABSTRACT | Context:Systemic arterial hypertension (SAH) is one of the main public health issues in our time. The etiology of SAH is known to be multifactorial. Regarding the factors associated with the development of this condition, literature has discussed the exposure to occupational factors as an independent risk for the development of hypertension. Objectives: This study aimed at conducting a literature review about occupational factors and systemic arterial hypertension. Methods: A search for papers published in a five-year period (2008)(2009)(2010)(2011)(2012) was carried out in the main electronic databases: SciELO, MEDLINE, and LILACS. Results: Among the occupational factors analyzed, noise stood out as being possibly associated with arterial hypertension, followed by working shifts. Conclusion: Even though the results indicate noise and working shifts as factors that are possibly associated with arterial hypertension, further studies about the subject are required -SAH and occupational factors -to improve the understanding of this theme.

“…But independently from age and other extra professional risk conditions, some work conditions are associated to a high risk of developing arterial hypertension [8][9][10][11]. In some studies, arterial hypertension has been associated more frequently with "blue collars" than with "white collars" [12], a positive association is also present in bus and taxi drivers [13], meaningfully higher compared to mechanical maintenance technicians [14,15]. Workers with exposition to noise superior to 85 dB(A) for longer than 30 years have shown a risk of hypertension 1,5 times higher [16].…”

For many years the Florentine area has been involved in carrying out big, infrastructure projects. These projects are very complex and the workforce employed to construct them, coming from all parts of Italy and also from abroad, are represented by workers with a high level of specialization, exposed to several and harmful risk factors. The majority live far from their family for long periods of time, mainly in base camps far from residential areas, sometimes isolated, without the possibility of dedicating their free time to social, cultural, sport and/or recreational activities. The objective of our study is to evaluate in this category of workers which working risk factors and styles of life represent a major risk factor for arterial hypertension which, in turn, significantly increases cardiovascular risk. A significant majority of workers carry out mansions of carpenter/soldered and of machine/excavator driver, in charge of dirt handling. The sample also includes numerous miners and drivers. The workers' average age is 45 years old and a high working seniority. Arterial hypertension is present in 139 subjects, equaling to 54% of the sample. The distribution of frequency of arterial hypertension is greater in the class of drivers, followed by the class of site managers and construction machines/excavator drivers. It is believed that the risk factors to which the workers studied are exposed, constitute elements that facilitate the onset of a state of arterial hypertension; among these, the stress correlated to a task which requires, lengthened attention and concentration, resulted as being the most important factor.Keywords: Workforce; Hypertension; Cardiovascular risk; Workers SummaryFor many years the Florentine area has been involved in carrying out big, infrastructure projects: construction of highways, viaducts and railroad tunnels for high speed trains. These projects are very complex and the workforce employed to construct them, coming from all parts of Italy and also from abroad, are represented by workers with a high level of specialization, exposed to several and harmful risk factors. The majority live far from their family for long periods of time, mainly in base camps far from residential areas, sometimes isolated, without the possibility of dedicating their free time to social, cultural, sport and/or recreational activities. The objective of our study is to evaluate in this category of workers which working risk factors and styles of life represent a major risk factor for arterial hypertension which, in turn, significantly increases cardiovascular risk. 257 workers were subject to three investigation instruments, following the French ESTEV methodology [1], modified in Italy by Barbini and Squadroni [2] and later by Barbini, Bigger [3]: one questionnaire was on professional conditions, one on the styles of extra work life, and was a medical questionnaire to obtain the objective health conditions of the workers. A significant majority of workers carry out mansions of carpenter/ solderer and ...

“…There is evidence that traffic noise interacts with the cardiovascular system (Babisch, 2008) and it has been directly linked to myocardial infarction (Babisch et al, 2005;Selander et al, 2009;Huss et al, 2010) and hypertension (Fuks et al, 2011;van Kempen and Babisch, 2012). Although elevated noise levels during resting periods and at night may be most critical, cumulative exposure to high noise levels in occupational settings has also been related to hypertension (van Kempen et al, 2002;Sbihi et al, 2008;Stokholm et al, 2013).…”

in this study, we assessed the mixed exposure of highway maintenance workers to airborne particles, noise, and gaseous co-pollutants. the aim was to provide a better understanding of the workers' exposure to facilitate the evaluation of short-term effects on cardiovascular health endpoints. to quantify the workers' exposure, we monitored 18 subjects during 50 nonconsecutive work shifts. Exposure assessment was based on personal and work site measurements and included fine particulate matter (PM 2.5 ), particle number concentration (PNC), noise (leq), and the gaseous co-pollutants: carbon monoxide, nitrogen dioxide, and ozone. Mean work shift PM 2.5 concentrations (gravimetric measurements) ranged from 20.3 to 321 μg m −3 (mean 62 μg m −3 ) and PNC were between 1.6 × 10 4 and 4.1 × 10 5 particles cm −3 (8.9 × 10 4 particles cm −3 ). Noise levels were generally high with leq over work shifts from 73.3 to 96.0 dB(a); the averaged leq over all work shifts was 87.2 dB(a). the highest exposure to fine and ultrafine particles was measured during grass mowing and lumbering when motorized brush cutters and chain saws were used. Highest noise levels, caused by pneumatic hammers, were measured during paving and guardrail repair. We found moderate spearman correlations between PNC and PM 2.5 (r = 0.56); PNC, PM 2.5 , and Co (r = 0.60 and r = 0.50) as well as PNC and noise (r = 0.50). Variability and correlation of parameters were influenced by work activities that included equipment causing combined air pollutant and noise emissions (e.g. brush cutters and chain saws). We conclude that highway maintenance workers are frequently exposed to elevated airborne particle and noise levels compared with the average population. this elevated exposure is a consequence of the permanent proximity to highway traffic with additional peak exposures caused by emissions of the work-related equipment.
