Resumo O objetivo deste estudo é identificar a prioridade perceptiva e de satisfação quanto aos atributos de conforto ambiental de profissionais adaptados ao clima tropical atuantes em Unidades de Terapia Intensiva (UTIs). Para tanto, avaliou-se, por meio de questionários de percepção e satisfação, profissionais de nove UTIs pertencentes à rede pública de saúde e localizados em cidade de clima tropical, além de medidas experimentais do ambiente. Os dados foram tratados por meio do método PROMETHEE e de testes inferenciais de Kruskal-Wallis e Mann-Whitney para identificação da sobreclassificação dos atributos de prioridade. Os resultados indicam que a temperatura do ar é o atributo de maior prioridade entre os profissionais intensivistas adaptados ao clima tropical, sendo a tolerância particularmente ao ruído distinta para diferentes valores de predicted mean vote (PMV). Conclui-se que uma avaliação de conforto ambiental deve considerar os atributos prioritários para os ocupantes, a fim de que a percepção e satisfação do ambiente global seja otimizada.

Abstract The aim of this study is to identify the perceptive priority and satisfaction related to environmental comfort attributes of professionals adapted to a tropical climate, who work in Intensive Care Units (ICUs). For this purpose, professionals from nine Intensive Care Units (ICUs) - in the public health network in a city with tropical climate - were assessed through perception and satisfaction questionnaires, in addition to experimental measurements of the environment. Data were treated using the PROMETHEE method and Kruskal-Wallis and Mann-Whitney inferential tests to identify the over classification of the priority attributes. The results indicate that air temperature is the highest priority attribute among the intensive care professionals adapted to a tropical climate, with tolerance to noise showing to be particularly different for different PMV (Predicted Mean Vote) values. The conclusion of the study is that environmental comfort assessments must consider the priority attributes for occupants in order to optimize the perception and satisfaction with the global environment.

Resumo Objetivou-se investigar o comportamento de modelos adaptativos de conforto térmico (PMVay e PMVak) em relação ao modelo clássico de Fanger (PMV) para predição da real sensação térmica nos profissionais intensivistas adaptados ao clima tropical, procurando identificar o limite de concordância entre tais métodos. As amostras foram coletadas em nove unidades de terapia intensiva (UTIs) públicas da cidade de João Pessoa/Paraíba/Brasil e as estimações obtidas pelos modelos foram confrontadas através da aplicação da análise de concordância entre métodos de Bland-Altman. Os testes identificaram que dentre os métodos selecionados o que apresentou menor viés para estimações da real sensação foi o PMV clássico se comparado aos modelos adaptativos indicados para indivíduos aclimatados a regiões quentes e úmidas características de climas tropicais. Entretanto, a amplitude do viés foi dependente da faixa de estimação, ou seja, à medida que as estimações se mantiveram entre valores de -1,5 e 0,2 o viés tendeu a ser minimizado. A análise de concordância mútua entre os testes mostrou que o PMV e o PMVak são equivalentes quando suas estimações se situam entre -0,5 e 0,5, o que indica que o fator de ponderação para adaptabilidade proposto pelo modelo PMVak não foi o suficiente para prever a aclimatação na amostra considerada.

Abstract The aim of this study was to investigate the behaviour of adaptive models of thermal comfort (aPMVy e aPMVk) as compared with the classical Fanger model (PMV) for the prediction of the actual thermal sensation of intensivist professionals adapted to the tropical climate, seeking to identify the limits of agreement between such methods. The samples were collected at nine public Intensive Care Units (ICUs) in the city of João Pessoa, Paraíba, Brazil and the estimates obtained by the models were compared by applying the concordance between Bland-Altman methods. The tests revealed that, among the selected methods, the one that showed the least bias estimating the real sensation was the classic PMV, compared with adaptive models indicated for individuals acclimatized to hot and humid regions, which are characteristic of tropical climates. However, the amplitude of the bias depended on the estimation range, i.e., as the estimation was kept between -1.5 and 0.2 values, the bias tended to be minimized. The mutual correlation analysis between tests showed that the PMV and aPMVk are equivalent when their estimates are between -0.5 and 0.5, indicating that the weighting factor for adaptability offered by the aPMVk model was not enough to provide acclimatization in the sample considered.

Abstract This study aimed to analyze the risk of musculoskeletal disorders in monofunctional and multifunctional workers in a footwear company. The sample comprised 114 workers in the shoe production sector. The method Occupational Repetitive Actions was used to assess the risk of work-related musculoskeletal disorders (WMSDs). Proportional odds models were constructed, relating the risk of WMSDs to the type of work and the worker’s level of multifunctionality. For monofunctional workers, exposure to the higher risk was related to cycle time and the technical actions within their activities, whereas for multifunctional workers, it was related to the range of motion, use of gloves and precision needed in activities. For monofunctional workers, greater risks were associated with a short activity cycle, whereas for multifunctional workers, they were associated with complementary and organizational factors. Moreover, workers whose intracellular activities were less than 30% of the total appeared to be less exposed to the risk of WMSDs.
