BACKGROUND: The prevalence and burden of cardiovascular disease (CVD) is a concern. While CVD events will occur later in a woman’s life, modifiable risk factors for CVD occur earlier during adult years. While, there is strong evidence linking modifiable risk factors to CVD, the influence of the work environment on CVD risk is poorly understood. OBJECTIVES: The study objectives were to: 1) determine the prevalence of cardiovascular risk indicators; 2) determine the relationships between work patterns and lifestyle behaviours in female hospital workers; 3) determine the relationships between work patterns and cardiovascular risk indicators; and 4) determine the relationships between work patterns, lifestyle behaviours and cardiovascular risk while controlling for covariates. METHODS: Participants were female hospital workers (N= 466) from 2 hospital sites in Southeastern Ontario. Cardiovascular risk data were obtained through anthropometric measurements, blood sampling and self-report. Work pattern data were collected through self-report and linked with hospital administrative work data. Lifestyle behaviour data were obtained through self-report using validated questionnaires. Metabolic syndrome was classified in accordance with the National Cholesterol Education Program Adult Treatment Panel (NCEP ATP) (III) guidelines. RESULTS: Approximately 1 in 4 female participants had the metabolic syndrome, with elevated waist circumference being the most common CVD risk factor. After adjustments, the multivariate analysis found a few key significant associations between irregular work patterns, specifically extended shifts and CVD risk, specifically elevated systolic and diastolic blood pressure. However, consistent with the literature, the bivariate analyses revealed that after 6 or more years of shift work, female workers were more likely to develop the metabolic syndrome (OR 1.9, 95% CI 1.12, 3.17) and abdominally obesity (OR = 2.0, 95% CI, 1.31, 3.11). CONCLUSIONS: The findings from this study suggest that generally work patterns do not influence the development of unhealthy behaviours and cardiovascular risk factors, although a few key exceptions exist. Further research is needed to elucidate the mechanisms linking harmful and protective work pattern characteristics to CVD risk. Given the prevalence of abdominal obesity and overall CVD risk, hospital decision makers need to consider cardiovascular health within healthy workplace initiatives as the healthcare workforce is aging. / Thesis (Master, Nursing) -- Queen's University, 2009-09-24 18:39:03.718

The implications of introducing shift work and flexible working hours into the UK clothing industry were examined, with special reference to the effects on personnel, plant utilisation and garment costs. A total of 37 garment manufacturing establishments, within 17 companies, were visited; 91 managers (for production and economic data)and 1018 supervisors and operatives, 87% female and 13% male, (for social data) were consulted. The main points arising from the survey are:- 1 . Social (i) The average age and length of service of respondents were respectively 30.4 and 7.1 for women and 40 and 13.9 for men. Nearly three fifths were married and over half of the women had children, most of them at school or pre-school stage. (ii) Over four fifths were committed to some kind of housework; 3 to 5 hours between 17.00 and 24.00 hours were usually spent on this task but about 9% spent more than 5 hours on it. (iii) Over half would be very much bothered by the inability to carry on their individual and/or group social activities. About two thirds would also be concerned by a change in the period of and time for sleep and meal times. Nearly two fifths used public transport for the journey to work. (iv) Only 15% had worked on multiple shifts previous to their present employment and 16% left their previous job because of being on shifts or unsuitable hours. About one fifth worked currently part-time and only 13% wanted to change their existing working system so that they might gain extra convenience and leisure in their working life. (v) The unsolicited personal choice of working systems were mainly shifts (13%), flexible working hours (14%) and part-time day work (30%); working only in school hours appeared to attract the choice of about 40% of the women. (vi) From the points above, it seemed that a high proportion of married female workers, mostly with dependent children and committed to housework, would probably react against shift work. The availability of part-time work together with the normal day work habit acquired would also affect the employees' attitudes towards the acceptance of even flexible working hours. 2. Production (i) The main problems involved with introducing shift work were considered to be sharing of equipment, bonus and piece rate payment and responsibility for quality failures. Dislike of sharing machines by operatives was considered to be a severe problem in sewing section and the extent of this dislike seemed higher in traditional rather than non traditional clothing areas; the operatives' age and length of service appeared to affect their attitudes. The smaller the period of time for each job then the less the problem of sharing payment and responsibility could become. (ii) Introduction of flexible working hours could create the difficulties of shortage and/or excess of supply of work within the production flow with interdependent operations; the extent of the problem could vary with the amount of work in progress and the period of time spent by each operative on the garment and/or its parts. Economic (i) Garment cost elements are material, labour, variable and fixed overheads (survey averages 50.6%, 24.9%, 8% and 16.5%), of which labour and variable overheads would be affected by introducing multiple shifts and only fixed overheads by flexible working hours. There should be a decrease in variable overheads per garment because of sharing a fixed amount of cost between shifts, an increase in labour cost due to shift premium and an increase in fixed overheads because of longer opening hours of the plant on flexible working hours. (ii) The capital employed on plant and machinery, C, could often be divided by the number of shifts so that this could help to increase profitability by a factor of 2 or 3. (iii) General formulae were established, using the most relevant variables, for calculating the profitability and profitability ratios of different working schemes. Generally, if the number of shifts are increased then the profitability of the plant could be very greatly increased. This was well illustrated from the calculated profitability ratios of about 2 and 3 respectively, when industrial survey values were used, for 2 and 3 shift systems replacing a single shift system. Profitability of flexible working hours would, theoretically, be less than that of single shift, but there might be some economic gains, such as reduced rates of labour turnover and absenteeism (which are currently high in the garment industry), arising from the introduction of flexible working hours.

Dentro de cada ser há um “relógio” interno que regula os ciclos diários da alimentação, sono, vigília, e até mesmo humor. É assim que ocorre: quando sentimos fome devemos comer e quando sentimos sono devemos dormir. As atividades diárias, a imposição de um horário, seja de trabalho ou escolar, afetam de maneira distinta cada pessoa, sendo que para algumas estas determinações atendem em “cheio” a suas preferências e para outras exigem um enorme esforço; muitas vezes, essa adaptação é impossível. Assim sendo, há horas do dia em que cada aluno está mais disposto a fazer determinadas tarefas, como as escolares entre outras. Neste contexto, identificaram-se os grupos de alunos quanto à alocação do ciclo vigília/sono: estudo de suas características e de suas relações com o processo de ensino aprendizagem, validando a Escala Matutino/Vespertino (que resultou no primeiro artigo citado nessa tese). Validada a Escala, o principal objetivo desta tese é relacionar os grupos de alunos de ambos os cronotipos (matutino/vespertino) com o turno escolar e o rendimento escolar, assim como algumas atividades que gosta de realizar fora da sala de aula, com alunos de uma escola pública de Ensino Médio e com alunos de cinco escolas públicas de Ensino Fundamental do Município de Farroupilha/RS. Observando que os resultados apresentados do Ensino Médio e Fundamental não foram os mesmos, foi analisado ao longo das idades da amostra, dos 11 aos 17 anos, foram relacionadas às variáveis: idade, cronotipo (matutino/vespertino), turno escolar, rendimento escolar e a taxa de reprovação. Os resultados levaram a conclusão que alunos matutinos do Ensino Fundamental (dos 11 aos 14 anos de idade) apresentam significativamente um rendimento escolar superior aos demais grupos de alunos no turno da manhã, consequentemente, menor taxa de reprovação. No Ensino Médio (15 aos 17 anos de idade) o grupo que apresentou rendimento significativamente superior aos demais grupos foi o dos alunos matutinos que estudam no turno da tarde. Os resultados contribuem para uma melhor compreensão entre o ritmo biológico/rendimento escolar/turno escolar em distintos níveis escolares e desta forma ajudar pais, escolas e políticas educacionais no sentido de aprimorar o processo de ensino-aprendizagem. O relato de caso aqui apresentado sugere uma interferência do ritmo circadiano no rendimento escolar. Entretanto, estudos com amostragens maiores e mais diversificados são necessários para propor este parâmetro como integrante de políticas públicas a serem adotadas evitando o efeito negativo do ciclo vigília/sono individual sobre o rendimento escolar. / Within each one there is a "clock" that regulates the internal dailycycles of eating, sleeping, waking, and even humor. So it happens: when we feel hungry we eat and when we feel sleepy we sleep. The daily activities, the setting of a time, affects each person differently, whether at work or school, and to some person these determinations is"perfect" to their preferences, and others determinations requires ahuge effort, and often, this adaptation is impossible. Thus, there are times of day that each student is more willing to do certain tasks, such as homework and others. In this context, we identified groups ofstudents by the allocation of the sleep / wake cycle, by studying their characteristics and their relationships with the teaching and learning process and validating the scale Morning / Evening, which resulted inthe first article of this thesis. With the validated scale, the main objective of this thesis is to associate groups of students from both chronotype (morning/afternoon) with school hours and school performance, at first with students from a public high school and later with students from five public schools in elementary school, in thecity of Farroupilha- RS. Noting that the results of the elementary school and high school were not the same, we analyzed the influence of the age of students: from 11 to 17 years. Related variables were: age, chronotype (morning / afternoon), school hours, school performance andfailure rate. The results showed that morning of elementary school students (from 11 to 14 years old) had a significantly higheracademic achievement to other groups of students on the morning shiftand a lower failure rate. In high school (15 to 17 years old), the morning group studying in the afternoon showed significantly higher yield than the other students. With this information, the schools, parents and the Departments of Education might rethink the best school hours to attend school and get better returns. Even the case report presented here suggest a circadian rhythm interference with school performance studies with a larger with sample is needed to indicate it as public politics to be adopted to avoid the negative effect of the sleep / wake cycle on individual school performance.

Esta pesquisa é um estudo de caso, com natureza exploratória, descritiva e comparativa de campo, transversal e com abordagem quantitativa. Tem como objetivo classificar as cirurgias em categorias, segundo a necessidade de horas de enfermagem em salas de operações, subsidiando o dimensionamento de pessoal de enfermagem em centro cirúrgico. Foi realizada em um Hospital geral, de grande porte, da rede privada da cidade de São Paulo. A amostra foi constituída de 140 pacientes, divididos em 14 grupos, sendo 10 pacientes em cada grupo. Para a formação dos grupos foi considerado a condição física do paciente, segundo Americam Society of Anestesiologists (ASA), o porte anestésico segundo a Associação Médica Brasileira (AMB), o tipo de procedimento anestésico-cirúrgico, invasivo ou minimamente invasivo (MI) e cirurgias eletivas. Quanto à condição física do paciente, os grupos foram formados com ASA1, ASA2 e ASA3; a ASA4 foi excluída por não apresentar casos, ASA 5 e 6 foram excluídos por serem cirurgias de urgência ou emergência. Quanto ao porte anestésico, as cirurgias foram classificadas em pequeno porte, médio porte, grande porte e porte especial. Desta forma os grupos ficaram simbolizados como: 1P, 1M, 1G, 1E, 2P, 2M, 2G, 2E, 3M, 3G, 3E, 1PMI, 1MMI e 2MMI. A coleta de dados foi realizada dentro das salas de operações, por meio de observação estruturada, a qual foi utilizado um roteiro com itens referentes à caracterização da cirurgia, recursos humanos, condição física do paciente e procedimentos anestésicos-cirúrgicos. O tratamento dos dados foi feito segundo a caracterização do paciente cirúrgico, horas utilizadas pelos recursos humanos e pelo paciente, procedimentos realizados e recursos materiais utilizados. Na comparação entre os grupos, a caracterização do paciente cirúrgico permitiu os seguintes resultados: quanto ao sexo, 83 (59,29%) do sexo feminino e 57 (40,71%) masculino, a maior frequência de idade foi entre 30 e 40 anos, em 34 (24,29%) dos pacientes. As especialidades cirúrgicas de maior frequência foram otorrinolaringologia em 23 (16,43%), ginecologia e obstetrícia 21 (15%) e ortopedia e traumatologia 21 (15%). A anestesia geral prevaleceu com 75 (53,58%) dos pacientes. Quanto aos distúrbios sistêmicos que caracterizaram a ASA, as doenças cardiovasculares prevaleceram em 52 (65%) dos pacientes, sendo 40 (50%) com hipertensão arterial sistêmica e 16 (20%) com diabetes Mellitus. Quanto às horas utilizadas, as média das horas utilizadas por paciente foram: 3,40 horas de enfermagem (HE); 0,10 horas de enfermeira (HEn); 3,28 horas de técnico/auxiliar de enfermagem (HT/A); 6,14 horas da equipe médica (HEM); 1,12 horas de cirurgia (HC); 1,95 horas de salas de operações (HSO); 0,21 horas de preparo para anestesia (HPA) e 0,16 horas de preparo para cirurgia (HPC). Para uma hora de cirurgia (HC), as médias de horas utilizadas em cada paciente foram: 3,54 HE; 0,14 HEn; 3,40 HT/A; 5,77 HEM e 1,90 HSO. Para uma hora de sala de operações (HSO), as médias de horas utilizadas em cada paciente foram: 1,81 HE; 0,06 HEn; 1,75 HT/A; 3,08 HEM e 0,54 HC. Quanto aos procedimentos realizados, as médias dos invasivos foi de 2,04 procedimentos e não invasivos de 5,70 procedimentos; com total de 7,74 procedimentos. A média de recursos materiais utilizados para anestesia foi de 4,19 equipamentos e para a cirurgia de 2,76 equipamentos; com total de 6,95 equipamentos. Na análise estatística dos grupos, referentes às ASA, segundo os portes anestésicos; os resultados demonstraram que os portes anestésicos pequeno e médio não diferiram significativamente entre si, sendo inferiores aos portes grande e especial, nas variáveis HE, HT/A, HEM; quanto aos portes anestésicos, segundo às ASA; os resultados demonstraram que quase não houve diferenças entres as ASA. Os grupos de cirurgias minimamente invasivas, houve diferença apenas nos recursos materiais, sendo superiores conforme o porte anestésico e a análise entre os grupos de cirurgias invasivas e minimamente invasivas, com portes anestésicos e ASA semelhantes, os resultados demonstraram que os grupos de cirurgias invasivas apresentaram - se significativamente inferiores nas variáveis estudadas em relação aos grupos de cirurgias minimamente invasivas. Desta forma, conclui-se com este estudo, que as HE estão relacionadas aos portes anestésicos, onde quanto mais complexo o procedimento anestésico-cirúrgico, mais horas de enfermagem são utilizadas, não foi observado relação das HE utilizadas com a condição física do paciente. Assim, foi elaborado uma classificação das cirurgias em categorias, segundo a necessidade de horas de enfermagem, para uma hora de sala de operações, sendo: cuidados padrão de enfermagem, com 1,41 horas; cuidados complexos de enfermagem, com 1,99 horas e cuidados diferenciados de enfermagem, com 1,78 horas / This is a case study with exploratory character, descriptive and comparative, and a fieldwork with a quantitative approach. It aims to classify the surgeries in categories according to the number of nursing hours in operating rooms, subsidizing the dimensioning of the nursing staff in operating rooms. It was performed in a large general private Hospital in São Paulo. The sample was constituted of 140 patients, divided into 14 groups, 10 patients on each group. To organize the groups it was taken on account the patient\'s physical condition, according to the American Society of Anesthesiologists (ASA), the anesthetic complexity, according to the Brazilian Medical Association (BMA), the sort of surgical anesthetic procedure: invasive, or minimally invasive (MI) and elective surgeries. According to the patient\'s physical condition, groups were constituted with ASA1, ASA2 and ASA3. ASA 4 was put away because there were no cases, and ASA 5 and ASA 6 were put away because they were urgency or emergency surgeries. As to the anesthetic complexity, surgeries were classified as presenting small complexity, mean complexity, large complexity and special complexity. Therefore groups were symbolized as: 1S, 1M, 1L, 1S, 2S, 2M, 2L, 2S, 3M, 3L, 3S, 1SMI, 1MMI AND 2AMI. Data were collect inside the operating rooms, by means of organized observation, according to a guide presenting items referring to the surgery characteristics, human resources, patient\'s physical condition and surgical anesthetic procedures. Data analysis was performed according to the surgical patient\'s characteristics, hours taken by human resources and by the patient, procedures and material resources employed. In the comparison among groups, the characterization of the surgical patient led to the following results: as to gender, 83 (59,29%) female and 57 (40,71%) male, the higher age frequency was between 30 and 40 years in 34 (24,29%) of the patients. The most frequent surgical specialties were otorhinolaryngology and traumatology in 23 (16,43%), gynecology and obstetrics in 21 (15%) and orthopedics and traumatology in 21 patients (15%). General anesthesia prevailed in 75 (53,58%) of the patients. Concerning the systemic disorders that characterize the ASA, cardiovascular disorders prevailed in 52 (65%) of the patients, 40 (50%) presenting systemic arterial hypertension and 16 (20%) presenting diabetes Mellitus. As to the hours taken, the average hours taken by patients was: 3,40 hours of nursing (NH); 0,10 hours of nurse (NeH); 3,28 hours of nursing assistant (NaH); 6,14 hours of medical staff (MSH); 1,12 hours of surgery (SH), 1,95 hours of operating room (ORH); 0,21 hours of anesthetic preparation (APH) and 0,16 hours of surgery preparation (SPH). For one SH, the average hours taken for each patient was: 3,54 NH; 0,14 NeH; 3,40 NaH; 3,08 MSH and 0,54 SH. Concerning to the procedures taken, the average of invasive procedures was 2,04 and non-invasive procedures 5,70; total procedures 7,74. The average material resources used for anesthesia was 4,19 equipment and for surgery 2,76 equipment; total 6,95 equipment. In the statistical analysis of groups referring to the ASA, according to the anesthetic complexity, results evidenced that small and mean anesthetic complexity presented no significant difference, and were inferior to large and special complexity in variables NH, NaH and MSH; as to the anesthetic complexity according to the ASA the results evidenced that there were almost none difference among the ASA. In the group of minimally invasive surgeries, there was difference only in the material resources, that were superior according to the anesthetic complexity and in the analysis comparing groups of invasive and minimally invasive surgeries with similar anesthetic complexity and ASA the results evidenced that groups of invasive surgeries were significantly inferior in the studied variables in relation to groups of minimally invasive surgeries. Therefore, this study concludes that the NH are related to the anesthetic complexity, and the more complex the anesthetic surgical procedure, the more nursing hours are taken. The relation of NH taken with the patient\'s physical condition was not observed. Thus a classification of surgeries in categories was done, according to the necessary nursing hours for one hour of operating room, that is: standard nursing cares, 1,41 hours; complex nursing cares, 1,99 hours and differentiate nursing cares, 1,78 hours
