ABSTRACT

This clinical guideline supported by the Brazilian Sleep Association comprises a brief history of the development of Brazilian sleep physiotherapy, outlines the role of the physiotherapist as part of a sleep health team, and describes the clinical guidelines in respect of the management of some sleep disorders by the physiotherapist (including sleep breathing disorders, i.e., obstructive sleep apnea, central sleep apnea, upper airway resistance syndrome, hypoventilation syndromes and overlap syndrome, and pediatric sleep breathing disorders; sleep bruxism; circadian rhythms disturbances; insomnia; and Willis-Ekbom disease/periodic limb movement disorder. This clinical practice guideline reflects the state of the art at the time of publication and will be reviewed and updated as new information becomes available.

ABSTRACT

OBJECTIVES: The prevalence of sleep problems in elderly, such as insomnia, is a relevant issue in our society. Poor sleep quality is viewed by many as an inevitable result of aging. In this context, this study aimed to estimate the prevalence and associated factors of sleeping disturbances in elderly men and women (60 years and older). METHODS: The present study is part of SABE Study (Health, Well-being and Aging), a cohort conducted in São Paulo, Brazil. The sample included in the present cross-sectional study comprised 1,334 elderly people aged 60 years or older. Sleep disturbances were assessed based on responses of study participants on whether they had experienced any sleep disturbance in the past month. RESULTS: Among the elderly assessed, 44.9% had overall sleep disturbances, which were more frequent in women (51.5%) and in 75 to 79 years old (48.2%). According to the regression analysis, the variables gender, joint diseases, as well as nocturia and urinary incontinence, were associated with sleep disorders. Increase in sleep disturbances was found not to be linearly age-dependent. CONCLUSIONS: Gender, pain, urinary and nocturia incontinence were factors associated with sleep disorders. Thus, we might conclude that the absence of sleep disturbances in older adults depends on gender and health status.


OBJETIVOS: A prevalência de problemas de sono em idosos, como insônia, é uma questão relevante em nossa sociedade. A má qualidade do sono, por exemplo, é vista por muitos como um resultado inevitável do envelhecimento. Neste contexto, este estudo teve como objetivo estimar a prevalência e os fatores associados a distúrbios do sono em homens e mulheres idosos (60 anos ou mais). MÉTODOS: O presente trabalho é parte do estudo de coorte Saúde, Bem-Estar e Envelhecimento (SABE), realizado em São Paulo, Brasil. A amostra deste estudo transversal constituiu-se de 1.334 idosos com 60 anos ou mais. Os distúrbios foram avaliados com base nas respostas dos participantes, levando em conta se eles tinham experimentado qualquer perturbação do sono no mês anterior. RESULTADOS: Dentre os avaliados, 44,9% indicaram distúrbios do sono em geral, sendo esses mais frequentes em mulheres (51,5%) e na faixa etária de 75 a 79 anos (48,2%). De acordo com a análise de regressão, gênero, doenças articulares, noctúria e incontinência urinária foram associados aos distúrbios, sobre os quais também foi verificado que seu aumento não é linearmente dependente da idade. CONCLUSÕES: Sexo, dor, incontinência urinária e noctúria são fatores associados a distúrbios do sono em idosos. Assim, concluímos que a sua ausência está associada ao gênero e ao estado de saúde.

ABSTRACT

PURPOSE: To elucidate the influence of leisure-time physical activity on body mass index (BMI), appetite-related hormones, and sleep when working irregular shifts. METHODS: A cross-sectional study was undertaken of 57 male truck drivers, 31 irregular-shift workers and 26 day-shift workers. Participants completed the International Physical Activity Questionnaire and were assessed for BMI. Subjects also provided a fasting blood sample for analysis of appetite-related hormones and wore an actigraphy device for seven consecutive days. RESULTS: Although leisure-time physical activity (LTPA) was generally low (<150 min/week) in both groups, the irregular-shift workers were more physically active than day-shift workers (99 ± 166 vs. 23 ± 76 min/week, p < 0.01). In spite of this, mean BMI of irregular-shift workers was 2 kg/m² greater than day-shift workers (28.4 ± 3.8 vs. 26.4 ± 3.6 kg/m², p = 0.04). Mean leptin concentration was 61 % higher in irregular-shift workers (5,205 ± 4,181 vs. 3,179 ± 2,413 pg/ml, p = 0.04). Among obese individuals, irregular-shift workers had higher leptin concentration (p < 0.01) and shorter sleep duration (p = 0.01) than obese day-shift workers. CONCLUSION: Elevated BMI was associated with high leptin and low ghrelin levels in this population of irregular-shift workers. No influence of LTPA on appetite-related hormones or sleep duration was found. We conclude that moderate LTPA is insufficient to attenuate the higher BMI associated with this type of irregular-shift work in truck drivers.

ABSTRACT

OBJECTIVE: To analyze the putative effect of type of shift and its interaction with leisure-time physical activity on cardiovascular risk factors in truck drivers. METHODS: A cross-sectional study was undertaken on 57 male truck drivers working at a transportation company, of whom 31 worked irregular shifts and 26 worked on the day-shift. Participants recorded their physical activity using the International Physical Activity Questionnaire along with measurements of blood pressure, body mass index and waist-hip ratio. Participants also provided a fasting blood sample for analysis of lipid-related outcomes. Data were analyzed using a factorial model which was covariate-controlled for age, smoking, work demand, control at work and social support. RESULTS: Most of the irregular-shift and day-shift workers worked more than 8 hours per day (67.7% and 73.1%, respectively). The mean duration of experience working the irregular schedule was 15.7 years. Day-shift workers had never engaged in irregular-shift work and had been working as a truck driver for 10.8 years on average. The irregular-shift drivers had lower work demand but less control compared to day-shift drivers (p < 0.05). Moderately-active irregular-shift workers had higher systolic and diastolic arterial pressures (143.7 and 93.2 mmHg, respectively) than moderately-active day-shift workers (116 and 73.3 mmHg, respectively) (p < 0.05) as well as higher total cholesterol concentrations (232.1 and 145 mg/dl, respectively) (p = 0.01). Irrespective of their physical activity, irregular-shift drivers had higher total cholesterol and LDL-cholesterol concentrations (211.8 and 135.7 mg/dl, respectively) than day-shift workers (161.9 and 96.7 mg/dl, respectively (ANCOVA, p < 0.05). CONCLUSIONS: Truck drivers are exposed to cardiovascular risk factors due to the characteristics of the job, such as high work demand, long working hours and time in this profession, regardless of shift type or leisure-time physical activity.

ABSTRACT

In mammalian, several evidences suggest that central serotonin participates in thermoregulation. Nucleus raphe obscurus (NRO), a serotonergic nucleus, has been recognized to be the source of generation of various hemodynamic patterns in different behavioral conditions, but its involvement in thermoregulation is unclear. In the present study, extracellular action potentials of NRO neurons were recorded in anesthetized rats, which were submitted to cold and warm stimuli in the tail. The firing rate of the neurons was compared before and after each stimulation. It was found that 59% of the neurons submitted to a cold stimulus trial had a significant increase in their firing frequency, while 48% of the neurons submitted to warm stimulation trial were inhibited. The opposite responses in neuronal activity of NRO units to cooling or heating suggest that these cells are involved in producing the homoeothermic vascular adaptations secondary to changes in cutaneous temperature in the rat tail.

A termorregulação em mamíferos envolve a participação da serotonina. O núcleo obscuro da rafe (NRO), que é serotoninérgico, participa do controle autonômico, mas seu envolvimento na termorregulação é incerto. Neste estudo, registramos potenciais de ação extracelulares de neurônios do NRO em ratos anestesiados nos quais a cauda foi submetida a estímulos de calor ou frio. A frequência de disparo dos neurônios foi comparada antes e depois dos estímulos. O grupo controle não apresentou modificação da frequência de disparo, enquanto que 59% dos neurônios registrados em animais submetidos a estímulo de frio tiveram sua frequência aumentada. Por outro lado, 48% dos animais submetidos a estímulo de calor tiveram sua frequência de disparo diminuída. As respostas opostas da frequência de disparo em neurônios de animais submetidos à estimulação com frio e calor sugere que estes neurônios estejam envolvidos na geração de respostas hemodinâmicas, que são coerentes com a termorregulação nesta espécie.

ABSTRACT

Introdução: Estudos mostram que motoristas de caminhão estão sujeitos a estressores no trabalho, tais como, por exemplo, a longa jornada de trabalho vinculada ao prazo curto de entrega de mercadorias, a vibração e o ruído do caminhão. O objetivo geral desse estudo foi avaliar os estressores ocupacionais e a concentração do cortisol em motoristas de caminhão, bem como a saúde física e mental desses trabalhadores, segundo os turnos de trabalho. Métodos: Participaram 57 motoristas de caminhão de uma transportadora de cargas que responderam a um inquérito sobre dados sociodemográficos, saúde, sono, condições de vida e trabalho, incluindo as dimensões da demanda, controle e satisfação no trabalho. Os motoristas usaram actímetros e tiveram suas medidas antropométricas e pressão arterial aferidas, além de exames bioquímicos de sangue. Posteriormente, 21 motoristas do turno diurno e 21 motoristas do turno irregular fizeram três coletas da saliva para análise da concentração do cortisol: ao acordar, após 30 minutos e ao dormir, durante um dia de trabalho e um dia de folga. Para análise dos dados, foi utilizado o teste de associação do qui-quadrado para as variáveis categóricas e testes de diferenças de médias, ANOVA e correlação de spearman para variáveis contínuas, considerando p<0,05. Resultados: Os trabalhadores do turno diurno tiveram concentrações de cortisol mais elevadas 30 minutos ao acordar durante o dia de trabalho em relação às do dia de folga (teste-t, p=0,03). Os motoristas do turno irregular tiveram maior concentração de cortisol quando comparados aos motoristas do turno diurno no dia de folga (ANOVA, p=0,03). Foi observada correlação entre os estressores no trabalho e as concentrações de cortisol dos trabalhadores de ambos os turnos. No caso dos motoristas do turno diurno, as concentrações de cortisol foram correlacionadas com o controle no trabalho (p=0,01, r=0,55), qualidade do sono (p=0,02, r=0,52) e ao tempo (em anos) de trabalho como motoristas (p=0,05, r=0,47). Em relação aos motoristas do turno irregular, a concentração do cortisol foi correlacionada com a satisfação no trabalho (p=0,03, r=-0,53), pressão arterial sistólica (p=0,03, r= 0,55), colesterol (p=0,03, r=0,55), curta duração do sono (p=0,02, r=-0,62) e fadiga após o trabalho (p= 0,03, r= 0,67). As prevalências dos distúrbios psíquicos menores foram de 7,7 por cento e 6,5 por cento nos motoristas dos turnos diurno e irregular, respectivamente. Os motoristas do turno irregular apresentaram maiores IMC, colesterol total, LDL e VLDL colesterol, além disso, relataram menor controle e demanda no trabalho e maior fadiga após o trabalho, comparados aos do turno diurno (p<0,05). Conclusão: Os motoristas apresentaram concentrações de cortisol mais elevadas no dia de trabalho em relação ao dia de folga. Os do turno irregular referiram piores condições de saúde e apresentaram concentrações de cortisol mais elevadas em relação aos motoristas do turno diurno, inclusive no dia de folga, sugerindo uma resposta mais prolongada ao estresse. Os valores do cortisol foram correlacionados com estressores no trabalho típicos desses profissionais de transporte, indicando a necessidade de melhorias para a categoria. Futuros estudos são necessários para investigar outras dimensões da resposta destes indivíduos aos estressores no trabalho, especialmente no caso de trabalhadores em turnos irregulares


Introduction: Studies have shown that truck drivers are subject to stressors at work, such as extended working hours due to short time to deliver the goods, the truck´s vibration and noise. The main objective of this study was to analyze the occupational stressors and cortisol levels among truck drivers, as well as their physical and mental health, by shift work. Methods: Participants were 57 truck drivers of a transportation company that filled in questionnaires about sociodemographic data, health, sleep, life style, work conditions, including the dimensions of job demand, control and job satisfaction. The drivers wore actigraphs and had measured their anthropometric data, blood pressure, besides biochemical blood tests. Then, 21 truck drivers of day shift and 21 of irregular shift did three salivary sampling to analyze cortisol levels: at waking time, 30 minutes after waking time and at bed time, in one working day and day off. Data analyses were performed using qui-square for categorical variables and mean difference tests, ANOVA and spearman correlation were performed for continuous variables, considering p<0,05. Results: Day shift workers had higher cortisol levels specially 30 minutes after waking time (p=0,03) in the working day compared to day off. Irregular shift workers had higher cortisol levels compared to day shift workers on the day off (ANOVA, p=0,03). Truck drivers in both shifts had their cortisol levels correlated with stressors at work. For day shift workers, the levels of cortisol were correlated to job control (p=0.01, r=0.55), sleep quality (p= 0.02, r=0.58) and years working as drivers (p=0.05, r=0.47), for example. For irregular shift workers, cortisol levels were correlated with job satisfaction (p=0.03, r=-0.53), blood pressure (p=0.03, r=0.55), cholesterol (p=0.03, r=0.55), short sleep duration (p=0.02, r=-0.62) and tiredness after working (p= 0.03, r= 0.67), for instance. The prevalence of minor psychiatric disorder was 7,7 per cent e 6,5 per cent , for day and irregular shift workers, respectively. The irregular shift workers had higher BMI, cholesterol, LDL and VLDL cholesterol, reported less demand, control and higher tiredness after working, compared to day shift workers (p<0,05). Conclusion: The drivers had higher cortisol levels on work day compared to days off. Moreover, the irregular shift workers had worst health profile and higher cortisol levels on their days off, compared to day workers, suggesting a prolonged stress response. Cortisol levels were correlated with typical stressors at truck drivers´ work, indicating the needs of better work conditions. Future studies are important to search others dimension of the response to stressors at work, especially for those who work in irregular shift

ABSTRACT

OBJETIVO: Estimar a prevalência de distúrbios psíquicos menores e identificar estressores associados entre motoristas de caminhão. MÉTODOS: Estudo transversal conduzido com 460 motoristas de caminhão de uma transportadora de cargas das regiões Sul e Sudeste do Brasil, em 2007. Os trabalhadores preencheram questionário com dados sociodemográficos, estilos de vida e condições de trabalho. As variáveis independentes foram condições de trabalho, incluindo estressores ocupacionais, satisfação e demanda-controle no trabalho. O desfecho avaliado foi a ocorrência de distúrbios psíquicos menores. Foram realizadas análises de regressão logística univariada e múltipla. RESULTADOS: A prevalência de distúrbios psíquicos menores foi de 6,1 por cento. Os estressores mais citados foram congestionamentos, controle de rastreamento e jornada extensa de trabalho. A alta demanda no trabalho, o baixo apoio social e a jornada extensa diária referidos pelos motoristas estiveram associados aos distúrbios psíquicos menores. CONCLUSÕES: O trabalho em jornadas extensas foi associado à ocorrência de distúrbios psíquicos menores, tanto na análise das condições gerais de trabalho quanto como fator referido como estressor pelos motoristas. A regulamentação da jornada de trabalho com limitação de horas de trabalho diário é, portanto, uma medida necessária para a redução da chance de desenvolvimento de distúrbios psíquicos menores em motoristas.

El resultado evaluado fue la ocurrencia de disturbios síquicos menores. Se realizaron análisis de regresión logística univariada y múltiple. RESULTADOS: La prevalencia de disturbios síquicos menores fue de 6,1%. Los estresores más citados fueron congestionamientos, control de rastreo y jornada extensa de trabajo. La alta demanda en el trabajo, el bajo apoyo social y la jornada extensa diaria referidos por los conductores estuvieron asociados a disturbios síquicos menores. CONCLUSIONES: El trabajo en jornadas extensas fue asociado a la ocurrencia de disturbios síquicos menores, tanto en el análisis de las condiciones generales de trabajo como el factor referido como estresor por los conductores. La regulación de la jornada de trabajo con limitación de horas de trabajo diario es, por lo tanto, una medida necesaria para la reducción de la probabilidad de desarrollo de disturbios síquicos menores en conductores.

ABSTRACT

OBJECTIVE: To estimate the prevalence of minor psychiatric disorders and to identify associated stressors among truck drivers. METHODS: A cross-sectional study was conducted with 460 truck drivers from a cargo transportation company of the Southern and Southeastern regions of Brazil, in 2007. Workers completed a questionnaire about sociodemographic, lifestyle and working conditions data. Working conditions were the independent variables, including occupational stressors, job satisfaction and job demand-control. The outcome evaluated was the occurrence of minor psychiatric disorders. Multiple and univariate logistic regression analyses were performed. RESULTS: The prevalence of minor psychiatric disorders was 6.1%. The most frequently reported stressors were traffic congestion, tracking control and extended working hours. High job demand, low social support and extended daily working hours, as reported by drivers, were associated with minor psychiatric disorders. CONCLUSIONS: Work involving extended working hours was associated with the occurrence of minor psychiatric disorders, both in the analysis of general working conditions and as a factor considered to be a stressor by drivers. Thus, regulation of working hours with focus on the limitation of the daily working hours is necessary to reduce the chance of developing minor psychiatric disorders in drivers.

ABSTRACT

Entre as doenças cardiovasculares, a hipertensão arterial sistêmica (HAS) merece destaque por ser a mais frequente, atingindo mais de 25% da população mundial adulta. Os motoristas de caminhão constituem uma população exposta a muitos dos fatores de risco para essa doença, como dietas inadequadas. Este estudo objetivou verificar a prevalência de HAS nessa população, seus fatores associados e se há diferenças nessa associação entre motoristas diurnos e noturnos. Foi realizado um estudo transversal com 470 indivíduos, majoritariamente do sexo masculino, que responderam de forma voluntária e autoaplicada aos questionários de dados sociodemográficos, antropométricos e de frequência alimentar. As variáveis que mostraram associação com HAS na regressão logística univariada (p<0,2) foram submetidas à regressão logística múltipla (p<0,05). Os resultados da análise conjunta dos motoristas mostraram associação estatisticamente significante entre HAS e idade, índice de massa corpórea (IMC), nível de escolaridade e vínculo empregatício. A porcentagem de hipertensos entre motoristas diurnos e noturnos foi equivalente, porém houve diferenças em relação aos fatores associados à doença, sendo o IMC a única variável que esteve presente em todas as análises. Isso sugere que fatores sociodemográficos, antropométricos e ocupacionais tenham influência sobre a HAS.


Among cardiovascular diseases, systemic arterial hypertension (SAH) deserves special attention, since it is the most common, affecting more than 25% of the worldwide adult population. Truck drivers are exposed to many risk factors for this disease, such as inadequate dietary habits. This study aimed to verify the prevalence of SAH in this population, its associated factors and if there are differences between night shift and day shift truck drivers. A transversal study was performed with 470 subjects, mostly males, which consented and answered self-assessment questionnaires about sociodemographic and anthropometric data, besides feeding frequency. The variables that were associated to SAH in the univariate logistic regression (p<0.2) were submitted to multiple logistic regression (p<0.05). The results of the analysis of all drivers have shown statistically significant association between SAH and age, body mass index (BMI), level of education and employment relationship. The percentage of hypertension on both day and night shift drivers was equivalent, but there were differences regarding factors associated to this disease, and the BMI was the only variable common to all analysis. This suggests that sociodemographic, anthropometric and occupational factors have influence on SAH.
