“…times greater prevalence of CVD, such as hypertension (130). Other findings strongly support the theory that noise exposure has an impact on hypertension, and some data suggest that hearing loss and hypertension severity is associated (131)(132)(133). As such, this cross-sectional data supports the need for further evaluation of noise and CVD.…”

Pandalai SP, Schulte PA, Miller DB. Conceptual heuristic models of the interrelationships between obesity and the occupational environment. Scand J Work Environ Health. 2013;39(3):221-232. doi:10.5271/sjweh.3363 Objective Research and interventions targeting the relationship between work, its attendant occupational hazards, and obesity are evolving but merit further consideration in the public health arena. In this discussion paper, conceptual heuristic models are described examining the role of obesity as both a risk factor and health outcome in the occupational setting.Methods PubMed was searched using specific criteria from 2000 and onwards for evidence to support conceptual models in which obesity serves as a risk factor for occupational disease or an outcome of occupational exposures. Nine models are presented: four where obesity is a risk factor and five where it is an adverse effect.Results A broad range of work-related health effects are associated with obesity including musculoskeletal disorders, asthma, liver disease, and cardiovascular disease, among others. Obesity can be associated with occupational hazards such as shift work, sedentary work, job stress, and exposure to some chemicals. Conclusion Identification of combinations of risk factors pertinent to obesity in the occupational environmentwill provide important guidance for research and prevention.Key terms cardiovascular disease; diet; endocrine disruptor; intervention study; metabolism; musculoskeletal disease; occupational health; physical activity; risk assessment.1 National Institute for Occupational Safety and Health, Centers for Disease Control and Prevention, Cincinnati, OH, USA.Correspondence to: Sudha P Pandalai, MD, PhD, National Institute for Occupational Safety and Health Centers for Disease Control and Prevention, 4676 Columbia Parkway, Cincinnati, OH 45226, Obesity is increasing worldwide with the 2009-2010 prevalence among US adults surpassing one-third (1, 2). Obesity is associated with genetic, behavioral, occupational, and environmental factors (3-5) and has significant economic impact (6). It is also associated with various health problems including musculoskeletal disorders (MSD), asthma, liver disease, and cardiovascular disease (CVD) (7-10). Moreover, neurohormonal and endocrine pathway disruption has been associated with obesity (11,12). Work factors, including sedentary work and taskrelated biomechanics, have been reported as risks for obesity (13)(14)(15). Variables such as irregular work hours/ sleep schedules, job stress, workplace absenteeism, and reduced productivity also contribute (16)(17)(18)(19).Although the related literature is growing, obesity in the occupational environment requires more study, for example, regarding low-wage workers and genes or other factors (20,21). Body mass index (BMI), a measure of obesity, varies by population, race, gender, and socioeconomic class (22)(23)(24). Genetics may account for ≥40% of the variation in BMI (25), but such estimates can depend on the variability of environ...

“…This finding is consistent with the results of chang et al, who found that noise-induced hearing loss at high frequency was significantly associated with hypertension even after controlling for potential confounders using multivariate logistic regression analysis 23 Also, in our final multivariate model, other co-variables such as age, smoking and positive family history were independently associated with high blood pressure. These co variables are established risk factors for high blood pressure in the biomedical literature 42-43…”

“…This was inconsistent with zawilla et al found no association between hypertension and hearing impairment or noiseinduced hearing loss (NIHL) 33 However, our result were consistent with a field study that reported significantly higher means of systolic blood pressure (SBP) and diastolic blood pressure (DBP) in workers with an auditory impairment ≥ 65 dB at 3, 4, or 6 kHz compared with those with normal hearing 24 . Similarly, chang et al reported that there was a significant difference between high hearing loss workers and the low hearing loss workers in the prevalence of hypertension, as 43.5% of the high level hearing loss workers had hypertension compared to only 33.2% of the low Hearing Loss workers 23 . Another study confirm our findings, as it reported a statistically significant prevalence of hypertension and electrocardiographic abnormalities among workers exposed to noise with audiometric deficit compared to workers exposed with normal hearing 34 .…”

Background: Workers in manufacturing industries are exposed to noise generated by the manufacturing processes that results in auditory and non-auditory effects on them. The relationship between occupational exposure to noise and blood pressure is subject to debate in occupational medicine Objective: the study objectives were to measure the prevalence of noise-induced hearing loss (NIHL) and hypertension among dry food factory workers and to determine the association between them Methods: a cross-sectional study was conducted among workers in dry foods factory. The study included 268 workers selected randomly from the four factory departments. All participants were subjected to pure tone audiometry, blood pressure measurements and BMI calculations, as well as personal and occupational history taking. Results: NIHL was present among 15.3% of workers (n=41); mild NIHL represented 65.9% of NIHL cases, moderate and severe NIHL represented 29.3% and 4.9% of cases respectively. Multivariate analysis showed that age, employment duration, smoking, and irregular use of personal protective devices (PPD) were significant risk factors for occupational NIHL. Hypertension was present among 16% (n=43) of workers. On multivariate analysis, hypertension were independently associated with longer employment duration, smoking, family history of hypertension, and NIHL. Conclusion NIHL and Hypertension were not uncommon among dry food factory workers. They were both associated with longer employment duration, and smoking. NIHL was strongly associated with the irregular use of PPD. Hypertension was significantly related to unprotected chronic exposure to noise. The strict usage of PPD can decrease the prevalence of both NIHL and hypertension among exposed workers

“…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.
