Comportamento alimentar e estado nutricional de trabalhadores em turnos: uma abordagem cronobiológica / Nutritional status and eating habits of shiftworkers: a chronobiological approach

Pasqua, Iara Cecília 20 May 2003 (has links)
Objetivos: O comportamento alimentar de trabalhadores em turnos fixos pode variar segundo a estação do ano e o horário de trabalho. Neste sentido realizou-se estudo com o objetivo de verificar a variação entre inverno e verão do comportamento alimentar e do estado nutricional de trabalhadores em turnos fixos. Também se verificou a distribuição circadiana da quantidade de calorias e macronutrientes da dieta e a ritmicidade circadiana das calorias da dieta dos trabalhadores. Metodologia: Foram estudados 28 trabalhadores de três turnos fixos (matutino, vespertino e noturno) de uma companhia de transporte de São Paulo. O consumo alimentar foi verificado pelo inquérito diário alimentar de três dias e o estado nutricional foi avaliado pelo índice de massa corporal, tanto no inverno quanto no verão. Testes paramétricas e não-paramétricas foram utilizados para comparar os grupos de trabalhadores e as estações. O Cosinor foi utilizado para verificar a ritmicidade circadiana das calorias da dieta dos trabalhadores. Resultados: A dieta dos trabalhadores forneceu uma quantidade maior de calorias (p=0,00), carboidratos (p=0,00) e lipídeos (p=0,03) no inverno. O índice de massa corporal dos trabalhadores, ao contrário, não variou de uma estação para outra (p=0,33). Comparando-se os grupos de trabalhadores não foram observadas diferenças quanto a quantidade de calorias (p=0,44), proteínas (p=0,78), carboidratos (p=0,59) e lipídeos (p=0,24) em nenhuma das estações, assim como não houve diferenças no índice de massa corporal no inverno (p=0,35) e no verão (p=0,35). Foi encontrado ritmo de calorias da dieta dos trabalhadores do turno matutino (p<0,05) e vespertino (p<0,05) nas duas estações. Conclusão: O comportamento alimentar de trabalhadores em turnos fixos variou de uma estação para outra, o que não se refletiu no índice de massa corporal. Os turnos de trabalho parecem não estar correlacionados com as mudanças sazonais observadas. No entanto, a distribuição do consumo alimentar ao longo das 24 horas pode ser um reflexo do turno ao qual o trabalhador está submetido. / Objectives: The eating habits of workers may vary according to the season of the year and the corresponding work schedule. A study aiming at verifying the variations occurring in their diet in summer and in winter, as well as the nutritional status of those who work in fixed shifts was carried out. The 24-hour distribution of the amount of calories and macronutrients ingested and the circadian rhythmicity of the calories contained in their diet were also analyzed. Methodology: The study was carried out with 28 workers subject to three fixed work shifts (morning, afternoon, and night) at a transport company in São Paulo. The food consumption was checked by using the 3-day dietary record, and their nutritional status was evaluated through the body mass index, both in winter and in summer. Parametric and non-parametric tests were performed so as to compare the different groups of workers and the seasons. The Cosinor method was utilized to verify the circadian rhythmicity of the calories included in their diet. Results: In winter, the workers typical diet contained a larger amount of calories (p=0,00), carbohydrates (p=0,00) and lipids (p=0,03). Their body mass index, on the other hand, did not show any variation from one season to another. The comparison carried out among the groups of workers did not show differences as to the amount of calories (p=0,44), proteins (p=0,78), carbohydrates (p=0,59) and lipids (p=0,24) in none of the seasons, and no differences as to the body mass index were observed, that is, the same index (p=0,35) was registered both in summer and winter. On both seasons a circadian rhythmicity of the calories was found in the workers belonging to the morning shift (p<0,05) and those belonging to the afternoon shift (p<0,05). Conclusion: The eating habits of workers subject to fixed shifts varied from one season to another, but the variation did not reflect upon their body mass index. In view of this, we might conclude that the work schedule (morning, afternoon, or night) do not seem to be related to the seasonal changes observed. Nevertheless, a 24-hour distribution of food intake may reflect upon the shift the worker is subject to.

Objetivo: Verificar a associação entre atividades físicas realizadas em diferentes períodos da vida, da adolescência à idade adulta, e obesidade abdominal em mulheres trabalhadoras de turnos. Métodos: Estudo de caso-controle não pareado realizado em 2011 com 541 mulheres trabalhadoras de turnos (215 casos; 326 controles), de 18 a 53 anos de idade, de uma empresa no sul do Brasil. Mulheres com circunferência da cintura ≥88 centímetros foram consideradas casos. Exposição à atividade física foi avaliada por um questionário com informações de atividades de lazer, deslocamento, doméstico e trabalho no campo em quatro períodos da vida. Para a análise foi utilizada a regressão logística não condicional. Resultados: A média da circunferência da cintura foi 97,5cm (desvio padrão [DP]:±8,5cm) nos casos e 78,7 (DP:±5,7cm) nos controles, e para a idade, a média foi 35,2 anos (DP:±8,6 anos) e 32,6 anos (DP:±8,4 anos), respectivamente. As atividades de lazer foram mais predominantes no período da adolescência com significativa redução na idade adulta tanto para os casos como controles. Após ajuste para fatores demográficos, socioeconômicos e ocupacionais, verificou-se que as mulheres com obesidade abdominal apresentaram uma chance 50% menor (Razão de Odds [OR]=0,50; Intervalo de Confiança de 95% [IC95%]:0,27 - 0,93;p=0,029) de terem praticado cinco ou mais atividades físicas quando comparadas às que praticaram uma ou nenhuma atividade física. Não foi identificada diferença nas atividades físicas de deslocamento, doméstico e de trabalho no campo entre casos e controles. Conclusões: Exposição a um maior número de atividades físicas de lazer na adolescência pode oferecer proteção para obesidade abdominal na vida adulta, mesmo que haja redução das atividades ao longo da vida. / Introduction: The practice of regular physical activity, especially during adolescence, may result in a physically active lifestyle in adulthood, as well as reduce the occurrence of cardiometabolic problems. Objective: To investigate the association between physical activities performed in different periods of life, from adolescence to adulthood, and abdominal obesity in women working shifts. Methods: A non-matched case-control study carried out in 2011 with 541 women (215 cases, 326 controls) from 18 to 53 years of age, of an industry in southern Brazil. Women with waist circumference ≥88cm were considered cases. Exposure to physical activity was assessed by a questionnaire with information on leisure-time, transport, housework and rural work in four periods of life. The non-conditional logistic regression was used for analysis. Results: The mean of the waist circumference was 97.5cm (standard deviation [SD]: ±8.5cm) in cases and 78.7 (SD: ±5.7cm) in controls, and for age, the average was 35.2 years (SD: ±8.6 years) and 32.6 years (SD: ±8.4 years), respectively. Leisure-time physical activities were most prevalent during adolescence with a significant reduction in adulthood for both cases and controls. After adjustment for demographic, socioeconomic and occupational factors, it was found that women with abdominal obesity had a 50% lower chance (Odds Ratio [OR]=0.50; 95% Confidential Interval [95% CI]: 0.27 to 0.93; p-value=0.029) of having practiced five or more physical activities than those who practiced of one or no physical activity. No difference was observed in the physical activities of transport, housework and rural work between cases and controls. Conclusions: Exposure to a greater number of leisure-time physical activities in adolescence may provide protection for abdominal obesity in adulthood, even with reduced of physical activity throughout life.

MÉTODOS: Foi realizado um estudo transversal com 1.206 trabalhadores, entre 18 e 50 anos, de ambos os sexos. Na investigação das características demográficas, socioeconômicas, turno de trabalho e hábitos alimentares, foram aplicados questionários padronizados. O turno de trabalho foi categorizado em diurno e noturno. Para investigar os hábitos alimentares dos trabalhadores, foram utilizadas três estratégias: (1) investigação do número e tipo das refeições realizadas, (2) horários das refeições e (3) construção de um escore alimentar. RESULTADOS: A prevalência de comportamento alimentar de risco entre os trabalhadores foi de 33,4% (IC95% 30,69 – 36,09). Após o ajuste, as mulheres não brancas e mais velhas apresentaram menor probabilidade de comportamento alimentar de risco. Com relação às refeições realizadas, um maior percentual de trabalhadores noturnos informou realizar 3 ou mais refeições ao dia. Os trabalhadores noturnos também apresentaram maior prevalência de consumo do lanche da tarde. Enquanto, os trabalhadores diurnos consumiam mais os lanches da manhã e da noite. Os trabalhadores noturnos e diurnos também apresentaram diferenças nos horários da realização das refeições. CONCLUSÃO: Evidenciou-se a relação das características demográficas dos trabalhadores com o comportamento alimentar de risco, bem como diferenças nos tipos de refeições realizadas conforme o trabalho em turnos. Esses achados sugerem a necessidade de que outros estudos específicos com trabalhadores sejam realizados para melhor elucidar as características dos hábitos alimentares dessa população. / OBJECTIVE: The aim of this study was to investigate the relationship between shift work and eating habits of workers in a poultry processing plant in southern Brazil. METHODS: A cross-sectional study was conducted with 1.206 workers, aged between 18 and 50 years, of both sexes. In order to investigate demographic and socioeconomic characteristics, shift work and food habits, standardized questionnaires were administered. Shift work was categorized as day and night shift. The investigation of the dietary habits of the workers was realized through three strategies: (1) research on the number and type of meals taken, (2) timing of meals and (3) building of a food score. RESULTS: The prevalence of risky eating behavior among workers was 33.4% (95% CI 30.69 to 36.09). After adjustment, older, nonwhite women were less likely to present risky eating behavior. With regard to meals, a higher percentage of shift workers reported having 3 or more meals a day. Night shift workers had higher prevalence of consuming afternoon snacks, whereas day shift workers consumed more snacks in the morning and evening. Night and day shift workers also had different timing for meals. CONCLUSION: It was concluded that there is a relationship between demographic characteristics of workers and risky eating behavior, as well as differences in the types of meal according to shift work. The findings suggest the need for specific studies with other workers to better elucidate the characteristics of the eating habits of this population.

Feeling of fatigue is an emotion associated with a psychophysiological state of fatigue. In addition to this, the specific objectives were: to propose and evaluate a methodological adaptation for data and methods triangulation in an integrative review; to contrast and reorganize the knowledge about the subjective measurement of fatigue at work; and to introduce a proposal for systemic aviation psychology, in order to contribute to the mitigation of human fatigue risk. This thesis was developed in the model format of a collection of articles. From the perspective that the systemic psychology research occurs in interdisciplinary context, and it contrasts globally, this work proposes an innovative methodology of triangulation to synthesize and discuss the available knowledge on the subject. This methodology is applied in an integrative review to synthesize qualitative and quantitative convergent data, among workers subject to work in shifts in order to reorganize the knowledge about the measure of fatigue with the feeling of fatigue scale. The results include a systemic meta-model of the phenomenon of fatigue and showed the psychometric validity of the scale. Then, the work describes the prevalence of fatigue at work among Brazilian civil aviation pilots, and demonstrates the validity of the feeling of fatigue scale in this context, from the perspective of systemic psychology. In order to do this, a crosssectional type study was conducted, in a sample of 1,066 Brazilian airline pilots. The results showed the psychometric validity of the scale, suggesting a prevalence of fatigue at work of Brazilian airline pilots of 59.4% (female) and 64.1% (male), with an average of fatigue at work above a cut-off that would define workers as fatigued. Finally, the systemic perspective suggests that one cannot reduce the causes of fatigue, being necessary to consider the context and the systemic mediation of symptoms associated. The study confirms that, in civil aviation, the feeling of fatigue is a valid measure of the nature and the level of fatigue at work, which can be assessed (screening) by means of the scale. / O objetivo geral da pesquisa foi investigar as evidências de validade da medida da fadiga no trabalho dos pilotos da aviação civil, por meio da escala de sentimento de fadiga, aderente à abordagem sistêmica da psicologia. O sentimento de fadiga é uma emoção associada a um estado psicofisiológico de fadiga. Além desse, os objetivos específicos foram: propor e avaliar uma adaptação metodológica para triangulação de dados e métodos em uma revisão integrativa; contrastar e reorganizar o conhecimento sobre a mensuração subjetiva da fadiga no trabalho; e introduzir uma proposta de psicologia sistêmica da aviação, a fim de contribuir para a mitigação do risco de fadiga humana. Esta tese foi desenvolvida no formato do modelo de coletânea de artigos. A partir da perspectiva de que a pesquisa em psicologia sistêmica ocorre em contexto interdisciplinar e se contrasta globalmente, propõe-se uma metodologia inovadora de triangulação para sintetizar e discutir o conhecimento disponível sobre o tema. Essa metodologia é aplicada em uma revisão integrativa para sintetizar dados qualitativos e quantitativos convergentes, entre trabalhadores sujeitos ao trabalho em turnos, de forma a reorganizar o conhecimento sobre a medida da fadiga com a escala de sentimento de fadiga. Os resultados permitiram construir um meta-modelo sistêmico explicativo do fenômeno da fadiga e evidenciaram a validade psicométrica da escala. Em seguida, o trabalho descreve a prevalência de fadiga no trabalho entre pilotos da aviação civil brasileira e demonstra a validade da escala de sentimento de fadiga naquele contexto, a partir da perspectiva da psicologia sistêmica. Para isso, foi realizado um estudo do tipo observacional transversal, em uma amostra de 1.066 pilotos de empresas aéreas brasileiras. Os resultados evidenciaram a validade psicométrica da escala, sugerindo uma prevalência da fadiga no trabalho dos pilotos de empresas aéreas brasileiras de 59,4% (feminino) e 64,1% (masculino), com uma média da fadiga no trabalho acima de um ponto de corte que definiria os trabalhadores como fatigados. Finalmente, a perspectiva sistêmica sugere que não se pode reduzir as causas da fadiga, sendo necessário considerar a mediação do contexto e o interrelacionamento sistêmico dos sintomas associados. O estudo confirma que, na aviação civil, a escala de sentimento de fadiga é uma medida válida da natureza e do nível da fadiga no trabalho, que pode ser avaliada (screening) por meio da escala.

Sömnbrist, trötthet och fatigue hos sjuksköterskor : En litteraturöversikt / Sleep deprivation, tiredness and fatigue on nurses : A literature review

Nensén Lagnefors, Cim, Nilsson, Emma January 2019 (has links)
Sömnbrist är ett ämne som givits allt mer uppmärksamhet i dagens samhälle. Sömnen har betydelse för människan i den bemärkelse att kroppen får återhämtning och hjärnan kan lagra och bearbeta minnen. Sjuksköterskor har i dagens samhälle en stor roll i det patientnära arbetet. Men vad händer med en sjuksköterska som har sömnbrist och hur påverkar detta hens arbete och hälsa? Syftet med detta arbete är att beskriva hur sjuksköterskor erfar sömnbrist, trötthet och fatigue samt hur det påverkar sjuksköterskans arbete och hälsa. En litteraturöversikt användes till arbetet för att få en överblick om det nuvarande kunskapsläget. Tio artiklar inkluderades i arbetet och analyserades. Studier visar på att sömnbrist, trötthet och fatigue är vanligt förekommande hos sjuksköterskor och studierna visade även på konsekvenser som uppstått till följd av sjuksköterskors trötthet. Dessa konsekvenser kan innebära att sjuksköterskor begår misstag i det patientnära arbetet, men tröttheten kan också gå ut över det privata livet. Detta innebär att sjuksköterskan kan utsätta sig för onödiga risker utanför arbetsplatsen i form av att köra bil medan hen är trött. Resultaten visar att det behövs mer forskning kring vilka orsaker som gör att sjuksköterskan lider av sömnbrist och därav upplever trötthet. Likaså studier som visar hur sömnbrist påverkar den vårdande vården vore värdefullt. En slutsats är att man bör lyfta frågan om sömnbrist och trötthet hos personalen för att på så sätt kunna se om rätt förutsättningar finns för en rimlig återhämtning.

No. of bitstreams: 1 Narriane Chaves Pereira de Holanda.pdf: 1302637 bytes, checksum: b468541773c5328d51e8317a0be8cba3 (MD5) Previous issue date: 2017-01-23 / Background: A relevant portion of the economically active world population is involved in some kind of night work and there are a relationship between shift work and short sleep duration. A few studies have shown the association between short sleep duration and negative consequences to the cardiometabolic health of night workers. The aim of this study was to analyze the association between shiftwork, sleep duration with metabolic syndrome risk factors in nursing personnel of a public hospital. Methods: A crosssectional study, involving nursing personnel of a children´s public hospital in João Pessoa, Brazil, was conducted. Sixty workers filled out a survey with socio-demographic, sleep (Karolinska Sleep Questionnaire), physical activity (International Physical Activity Questionnaire), Karasek's Job Demands-Control, and nutrition data (16-Food Intake Questionnaire). Body measurements and blood pressure were taken and blood was collected for glycemia, total cholesterol and portions of low-density lipoprotein and highdensity lipoprotein, triglycerides and leptin. The sample was divided into three groups according to the work shift of the participants (only morning shift, mixed - morning and night shifts, ex-night shift). To do the statistical analyzes, tests of the difference of the average of quantitative variables were done (ANOVA and Kruskal Wallis) and tests of proportion (chi-square test and Fisher exact) of quantitative variables to compare the three groups. In all tests was considered p < 0,05 as significant. The program used was the STATA 12.0 (Stata corp, Texas, USA). The ethical questions involving people were respected. Results: The participants average age was 39.8 years old (SD=10.5 years old). The prevalence of the metabolic syndrome in the studied population was 32%, however, there was no significant differences among the groups. Also, there were no significant differences among the studied groups regarding to socio-demographic, physical activity, food patterns, health characteristics, and job demands-control categories. Nevertheless, the group of morning and night workers reported sleep less (p<0.01), and showed a higher sleep debt (p<0.01) than the other groups in workdays. In addition, the higher proportion of workers with hypertriglyceridemia (TG ¿ 200 mg/dl; p=0.03) and diastolic arterial hypertension (DAP ¿ 90 mmHg; p=0.01) was observed in the morning and night shift group. Conclusion: The prevalence of metabolic syndrome in the studied population was above the general population. Although no differences were observed among the groups, the one which includes night shift showed more sleep disturbances than the others, and higher prevalence of two out of three risk factors to the metabolic syndrome diagnosis. The relationship between MS and shift work should be investigated in the light of work activity. / Introdução: Importante parcela da população mundial economicamente ativa está envolvida em algum tipo de trabalho noturno. Este tipo de trabalho promove dessincronização do ciclo virgília-sono e prejuízo do sono destes trabalhadores; e vários estudos observacionais têm demonstrado a associação entre sono de curta duração e consequências negativas para a sáude cardiometabólica. Objetivo: Analisar a relação entre o trabalho turno de trabalho, sono de curta duração e síndrome metabólica em uma equipe de enfermagem. Métodos: Tratou-se de um estudo epidemiológico do tipo transversal envolvendo funcionárias da enfermagem de um hospital infantil, situado na cidade de João Pessoa-PB. Sessenta profissionais responderam questões sociodemográficas e questionários validados internacionalmente sobre sono (Questionário Karolinska), prática de atividade física (IPAQ-SF), binômio demanda-trabalho (Job Scale, versão curta) e nutrição (16-FIQ). Foram aferidas medidas antropométricas, da pressão arterial e realizada coleta de sangue para avaliação bioquímica da glicemia de jejum, colesterol total e frações, triglicerídeos e leptina. Para as análises estatísticas foram realizados testes de diferença de médias das variáveis quantitativas (ANOVA e Kruskal Wallis), assim como testes de proporções (qui-quadrado e exato de Fisher) das variáveis qualitativas para comparar os três grupos. Em todos os testes foi considerado significante o valor de ¿p¿ menor que 0,05. O programa utilizado foi o STATA 12.0 (Stata corp, Texas, USA). As questões éticas de pesquisa envolvendo seres humanos foram devidamente respeitadas. Resultados: A amostra foi dividida em três grupos, de acordo com o turno de trabalho exercido pelas participantes (diurno, misto - diurno e noturno, e ex-noturno). A idade média das participantes foi 39,8 anos (DP=10,5 anos), variando de 26 a 66 anos. A prevalência da síndrome metabólica na população estudada foi de 32%, estando acima da média da população geral. Entretanto, não houve diferença significativa entre os grupos estudados. Não houve diferença significativa entre os grupos estudados quanto às características sociodemográficas, de saúde, prática de atividade física, padrão alimentar e categorias de demanda e controle no ambiente de trabalho. As trabalhadoras diurnas e noturnas relataram dormir menos (p<0,01) e apresentaram um maior débito de sono (p<0,01), quando comparadas às trabalhadoras diurnas e ex-noturnas. Além disso, este grupo apresentou mais hipertrigliceridemia franca (TG ¿ 200 mg/dl) (p=0,03) e hipertensão arterial diastólica (PAD ¿ 90 mmHg) (p=0,01). Conclusão: A prevalência de síndrome metabólica na população estudada foi maior que a da população geral. Embora nenhuma diferença tenha sido observada entre os grupos, o grupo que incluiu trabalhadoras noturnas apresentou mais distúrbios do sono, além de uma maior prevalência de dois de três fatores de risco para o diagnóstico de síndrome metabólica.

Work-related injuries in a midwestern manufacturing facility

Gross, Nathan Alan 01 May 2016 (has links)
Work-related injuries are a persistent problem in the manufacturing industry. This research focuses on factors involved in the incidence, severity, and effective treatment of work-related injuries in a population of manufacturing workers. Data from a large Midwestern manufacturing facility were obtained with the aims of measuring the association between shift work and injury incidence, measuring the impact of injury reporting lag on injury severity, describing an intervention designed to provide expedited treatment to injured workers, and describing worker and injury characteristics associated with treatment success. Using injury and employment data from the Midwestern manufacturing facility for the years 2011 and 2012, we found that workers on second shift had a marginally significant increase in injury incidence compared to first shift workers. No differences were observed between third shift and first shift workers. Gender and job tenure were also found to be associated with increased injury rates. Job tenure was, in fact, a more significant predictor of injury than age. Using injury data from the years 2011 and 2012, we found that delayed injury reporting had a significant impact on injury severity. As the lag time increased between the date of injury and the injury report date, so too did the odds that the injury would lead to restricted work days. We did not, however, find the same association between reporting lag and lost work days. Injury type was a significant predictor of both restricted and lost days. Job tenure and body part injured were also predictors of lost days. Finally, we collected data from the years 2007-2009 on injured workers treated for musculoskeletal disorders through an intervention designed to reduce treatment lag time. The intervention, delivered by occupational health nurses and physical therapists, provided injured workers with a physical therapy visit within three days of reporting an injury. The intervention was designed to circumvent two barriers to timely care, the delay between the injury report date and the first occupational health physician visit, and the delay between the first physician visit and the first physical therapy visit. The most significant predictor of program discharge success was patient age. Older workers tended to have lower odds of being discharged to their baseline work duties compared to young workers. Overall, nearly two-thirds of the injured workers referred to the program were successfully discharged, regardless of gender, body part injured, cause of injury, or nature of injury. This project addresses the important issue of injuries in the manufacturing industry. We provide evidence on the factors associated with injury incidence and injury severity among workers in a large Midwestern manufacturing facility. We also show that workplace injury treatment interventions directed by occupational health nurses and physical therapists can be very effective in returning injured workers to their regular job duties. Our evidence suggests that future research and injury prevention efforts should focus on shift workers, low tenured workers, reducing delayed injury reporting, and reducing delayed injury treatment.

Den inre klockan i obalans : en kvalitativ studie om hur kostvanor och måltidsmönster påverkas av skiftarbete / The internal clock out of balance : a qualitative study on how eating habits and meal patterns are affected by shift work

Granholm, Alexandra January 2011 (has links)
Syfte och frågeställningar Syftet med studien var att få en uppfattning om hur kosten och måltidsmönstret påverkas av en oregelbunden dygnsrytm hos skiftarbetande poliser. Syftet var också att skapa en bild av hur och vilka metoder som används för att skapa goda kost- och sömnrutiner i vardagen. Specifika frågeställningar var hur poliser upplever att deras kostvanor och måltidsmönster påverkas av skiftarbete med en oregelbunden dygnsrytm samt vilka livsstrategier som används för att hantera kost- och sömnvanor som skiftarbetande polis. Metod Datainsamlingen är baserad på intervjuer med fyra poliser, två kvinnliga och två manliga i åldrarna 26 till 37 år, som arbetar i en närförort till Stockholm. Respondenterna valdes ut med hjälp av bekvämlighetsurval via en bekant inom polisen. Samtliga deltagare kontaktades via telefon för att bli informerade om studiens syfte, frågeställningar, genomförande, för att boka in tid för intervju och blev dessutom upplysta om att de har full anonymitet i studien. Veckan innan intervjuerna ägde rum gjordes en pilotintervju med kontaktpersonen. Dagen innan deltagarna intervjuades mejlades frågorna ut. Samtliga intervjuer, förutom den sista, hölls på polisstationen i ett avskilt rum. Den sista intervjun var en telefonintervju. De tre första intervjuerna spelades in med hjälp av en diktafon, för att sedan ordagrant kunna transkriberas, bearbetas och analyseras. Den fjärde intervjun spelades in med hjälp av en mobil, varefter filen överfördes till dator. Resultat och slutsats Respondenternas svar visade individuella skillnader i upplevelsen av hur kosten påverkas av skiftarbete och en oregelbunden dygnsrytm. Regelbundenheten i måltidsmönstret verkar vara mest lidande av detta. Det finns en tendens till att måltiderna förskjuts och att poliserna missar framförallt lunchen, ifall de har arbetat nattskift. I stället äts någon form av frukost två gånger per dag. Livsstrategierna som används skulle kunna förbättras, för att ytterligare skapa bättre regelbundenhet i vardagen. / Aim The aim of this study was to gain insight into how the diet and meal pattern of shift working police officers is affected by an irregular daily routine. The purpose was also to illustrate how and what methods are used to create healthy eating and sleeping routines in everyday life. More specifically, the research questions were how police officers experience that their eating habits and meal patterns are affected by shift work with irregular daily routines and what life strategies are used to handle diet and sleeping habits as a shift working police officer. Method The data collection is based on interviews with four police officers, of whom two are female and two male between the ages of 26 and 37 years and work at a police station in the Stockholm area. The respondents were selected on the basis of convenience sample through an acquaintance within the police. All participants were contacted via telephone and were informed of the study’s purpose, research questions and method before an interview was booked. They were also informed of the fact that they would remain anonymous. A pilot interview was held with the contact person one week prior to the interviews. The participants received the interview questions by e-mail the day before the interview. All interviews, apart from the final one, were conducted at the police station in a private room. The last interview was held over the phone. The first three interviews were recorded with a dictaphone and were later transcribed, revised and analyzed. The fourth interview was recorded with a cellphone, after which the sound file was transferred to a computer. Results and conclusions The results highlighted individual differences in the experience of how the diet is affected by shift work and an irregular daily routine. The regularity of the meal pattern appears to suffer the most. There is a tendency that the meals are displaced and that the police officers primarily miss out on lunch in case they have worked a night shift. Instead they eat some form of breakfast twice per day. The life strategies that are used could be enhanced in order to create better regularity in the police officers’ everyday lives.

Sleeping in a society : social aspects of sleep within colonies of honey bees (Apis mellifera)

Klein, Barrett Anthony 02 August 2011 (has links)
Sleep is a behavioral condition fraught with mystery. Its definition—either a suite of diagnostic behavioral characters, electrophysiological signatures, or a combination of the two—varies in the literature and lacks an over-arching purpose. In spite of these vagaries, sleep supports a large and dynamic research community studying the mechanisms, ontogeny, possible functions and, to a lesser degree, its evolution across vertebrates and in a small number of invertebrates. Sleep has been described and examined in many social organisms, including eusocial honey bees (Apis mellifera), but the role of sleep within societies has rarely been addressed in non-human animals. I investigated uniquely social aspects of sleep within honey bees by asking basic questions relating to who sleeps, when and where individuals sleep, the flexibility of sleep, and why sleep is important within colonies of insects. First, I investigated caste-dependent sleep patterns in honey bees and report that younger workers (cell cleaners and nurse bees) exhibit arrhythmic and brief sleep bouts primarily while inside comb cells, while older workers (food storers and foragers) display periodic, longer sleep bouts primarily outside of cells. Next, I mapped sleep using remote thermal sensing across colonies of honey bees after introducing newly eclosed workers to experimental colonies and following them through periods of their adult lives. Bees tended to sleep outside of cells closer to the edge of the hive than when asleep inside cells or awake, and exhibited caste-dependent thermal patterns, both temporally and spatially. Wishing to test the flexibility of sleep, I trained foragers to a feeder and made a food resource available early in the morning or late in the afternoon. The bees were forced to shift their foraging schedule, which consequently also shifted their sleep schedule. Finally, I sleep-deprived a subset of foragers within a colony by employing a magnetic “insominator” to test for changes in their signaling precision. Sleep-deprived foragers exhibited reduced precision when encoding direction information to food sources in their waggle dances. These studies reveal patterns and one possible purpose of sleep in the context of a society. / text

Måltidens betydelse på arbetsplatsen : Enstudie av ett sjukhus, ett regemente och en industri

Meller, Louise January 2013 (has links)
De flesta människor tillbringar idag en stor del av sitt liv på arbetet. Eftersom ett av dagens huvudmål intas på arbetsplatsen är det av stor betydelse för individens hälsa att denna uppfyller önskemål och riktlinjer för en god och hälsosam måltid. Arbetsmåltiden är en möjlig återhämtande paus under arbetet och det är viktigt att den fyller flera viktiga funktioner både sociala och fysiologiska. Arbetsmåltidens kvalitativa helhet är angelägen för både arbetsgivare och individ då den troligtvis påverkar både prestation och arbetshälsa. Genom att prioritera attraktiva och näringsriktiga måltider på arbetet ökar förmodligen tillfredsställelsen hos de anställda. Syftet med denna studie var att undersöka de anställdas inställning och hur de värderade sin måltid på arbetet. I undersökningen deltog anställda från tre olika arbetsplatser i Skaraborgs län: ett sjukhus, en industri och ett regemente. Data samlades in från en tidigare enkätstudie som innehöll flervalsfrågor, skalfrågor och öppna frågor. Det var totalt 940 enkäter med 20 frågeområden som delades ut till samtliga tre arbetsplatser. Bortfallet på sjukhuset var 21%, på industrin 16% och på regementet 29%. Denna studie behandlar endast innehållet i svaren på de två öppna frågorna. Totalt var det 182 svar och innehållet sammanställdes genom innehållsanalys. Resultatet i studien visade att personalen var relativt missnöjd med sin arbetsmåltid och efterfrågade en mer hälsosam och varierad kost samt bättre kvalitet och kunskap från matleverantörens sida. Några exempel var att personalen önskade ett bättre utbud av sallad och grönsaker, de önskade också att måltidspersonalen hade mer kunskaper kring hälsosam mat. De tyckte också att det saknades inspiration och nytänkande då de upplevde maten ensidig, smaklös och ohälsosam. Ett annat problem var miljön i matsalen, det skapades irritation över att köer till kassor var långa och resulterade i att lunchrasten blev kort. Ljudnivån var ofta hög och oacceptabel och det skapade otrivsel i matrummet. / Today most people spend much of their lives at work. As one of today´s main meals probably is taken at work, it is very important that this meal meets the requirement and guidelines for a healthy and good meal . Since the meal may be a recovery break from work it is important that it fulfill several important functions both social and physiological. The quality of meal at work is certainly important for both employers and individuals as energy and nutrients affects both the performance and occupational health. Giving priority to attractive and nutritious meals at work probably increase the satisfaction of the employees. The purpose of this study was to examine the employees attitudes and valuation for their meal at work. The study included employees from three workplaces, a hospital, a regiment (armed forces) and a manufacturing base. Data were collected from a previous survey study which included multiple choice questions, scale questions and open questions in the questionnaire. A total of 940 surveys with 20 question areas were distributed to all three worksites. A loss of response rate was for the hospital 21%, for the industry 16% and for the regiment 29%. This study covers only the answers of the two open questions. In total there were 182 responses and the contents compiled through a content analysis. The results of this study showed that employees were relatively dissatisfied with their working meal and requested a healthier and more varied diet at their work place. Better quality and expertise from the food supplier was also in demand. Some examples was that they wanted a better selection of salads and vegetables. They also wished that the meal staff had more knowledge about healthy eating. They thought it was no inspiration and new ideas. They experienced the food monotonous, tasteless and unhealthy. Another problem was the environment in the canteen. It generated irritation that queues at checkouts were long and resulted in short lunch break. The noise level was often high and unacceptable and it created dissatisfaction in the canteen.
