Cardiovascular Disease as Cause for Disability Pensions

Abstract Introduction: In the last three years, in Brazil, most disability pensions (DP) were granted to cardiovascular diseases (CVD). Objective: To identify CVD as a cause of DP. Method: Literature review, including articles from 2000 to 2013, using the following descriptors: risk factors, pensions and cardiovascular diseases in the Pubmed/Medline, bireme, scopus, web of science and cochrane databases: After excluding duplicated items, articles not written in English or Portuguese and those not relatedto the topic of study, 7 papers remained. Results: All papers showed a positive association between DP and CVD. In one study that used relative risk to compare retirement between CVD and musculoskeletal disability, no difference was found between the groups. In other studies there was association between increased uric acid, poorly controlled hypertension, perception of stressful work and inadequate postures at work with increased risk for retirement. Discussion: There are high investments in preventive campaigns for the worker’s health in the area of musculoskeletal disorders, but not always the same commitment to the prevention of CVD. Conclusion: The CVD has high significance for the health of the worker, being a major risk factor for DP, and the implementation of policies to prevent these diseases should be encouraged.

0294 Cardiovascular disease as a risk factor for disability retirement

Objectives The relationship between work and some diseases that they can provide is already known for a long time. Because of these conditions some projects were created to improve conditions of work and to support the worker loses her job capacity such, among them the disability retirement. The objective of this study was to identify cardiovascular disease as risk factors for disability retirement. Method Was realised a literature review, including articles published in 2000 to 2013, being surveyed those in the period from April to November 2013, using the following descriptors: risk factors, pensions and cardiovascular diseases in databases PUBMED/MEDLINE, BIREME, SCOPUS, WEB OF SCIENCE and COCHRANE. Found, respectively, 8, 8, 27, 2 and 0 items. After deleting the duplicate items, those whom were not in English or Portuguese and non revolved around the topic of study, 7 remained. All showed a positive association between disability retirement and cardiovascular diseases. Results In the study used to compare relative risk for cardiovascular disease retirements with musculoskeletal found the same risk for both diseases. Other studies showed association between increased uric acid, poorly controlled hypertension, perceived stressful work postures and work and increased risk for this retirement. There is a huge investment in prevention campaigns for workers’ health to prevent the musculoskeletal disease, but not always the same commitment to the prevention of the cardiovascular. Conclusions In conclusion cardiovascular disease has high significance for the health of the employee, being an important risk factor for disability retirement, and should be encouraged to implement policies to prevent these.

533 Evaluation of subjective scales for measuring mental workload: literature review

Introduction Workers’ mental health should be valued since the causes of work abandonment due to problems related to mental health already occupy the first position in the statistics in some countries. Knowledge about the means of measuring the mental load in the work environment can help the occupational health team to identify causes of absence, propose ways of prevention, seeking a better adaptation of the work cycle to the worker. The comprehension of the measurement methods available in the literature also helps to guide the choice of the most appropriate scale according to the type of demand to be applied. Methods Literature review about the forms of evaluation of mental workload, carried out between June and November of 2016, using the following descriptors combined: ‘occupational mental load’, ‘Mental work load’, and ‘NASA-TLX’ at SciELO, Lilacs and Medline databases. Result A total of 34 articles were selected, of which 80% used the NASA-TLX scale as a method of analysis or as a comparison for validation of new scales. Discussion The mental workload scales should be selected according to what is prioritised in the research results. In addition, variability may occur in the application of the same scale with different populations; which corroborates with the definition that the mental load has factors that are specific to the individual and his sociocultural environment. Thus, external and personal factors may interfere in different ways in the assessment of mental load expenditures according to the task.

Avaliação da qualidade de vida de açougueiros com a utilização do WHOQOL-bref

Background There is a global shortage of individuals for jobs that require special skills and techniques, such as butchers. As a result, the available workers are overloaded, which might impair their quality of life. Objective To assess the quality of life of butchers working for a network of butcher shops in Sao Paulo. Method Cross-sectional observational study with a selected group of butchers and a control group, with age ranging from 18 to 45 years old and from both genders. A quality of life questionnaire (World Health Organization Quality of Life, bref - WHOQOL-bref) was applied to a sample of 50 butchers and 50 controls. Results The scores for butchers were statistically significantly lower in all quality of life variables, except for self-assessment compared to the controls (p<0.05) even after adjustment for characteristics differing between the groups. Conclusion The present study provides data poorly investigated in other studies, and suggests that assessment of the perception of the quality of life of butchers should continue.Background There is a global shortage of individuals for jobs that require special skills and techniques, such as butchers.

0297 The prevalence of risk factors associated with Computer Vision Syndrome among computer works in São Paulo, Brazil

Objectives The aims of this study were to investigate work conditions, to estimate the prevalence and to describe risk factors associated with Computer Vision Syndrome among computer works in São Paulo. Method The methods include a quantitative cross-sectional observational study and an ergonomic work analysis, using work observation, interviews and questionnaires. The case definition was the presence of one or more specific ocular symptoms answered as always, often or sometimes. The multiple logistic regression model, were created using the stepwise forward likelihood method and remained the variables with levels below 5% (p < 0.05). Results The operators were mainly female and young (from 15 to 24 years old). The call centre was opened 24 h and the operators weekly hours were 36 h with break time from 21 to 35 min per day. The symptoms reported were eye fatigue (73.9%), “weight” in the eyes (68.2%), “burning” eyes (54.6%), tearing (43.9%) and weakening of vision (43.5%). The prevalence of Computer Vision Syndrome was 54.6%. Conclusions The organisation and psychosocial factors at work should be included in prevention programs of visual syndrome among call centres’ operators.

0303 Conditions of return to work of nurses after maternity leave

Objectives Currently, countries like France, Spain, Italy, United States and Brazil there was an increase in the proportion of workers aged between 25–45 years, a period considered fertile. This scenario has determined that many workers had to choose between career and motherhood. The aim is to analyse the amount of Brazilian nursing professionals, in the period from January, 2012 to July 2013, returned to work after maternity leave. Method Was performed a literature review at Pub Med and BIREME. There was a review of the medical records of nursing professionals met at a public university hospital of São PAulo, Brazil, from January 2012 to July 2013. Results Returned to work after maternity leave: 80% (57) of nursing assistants, 70% (16) of the nursing staff and 94.6% (53) of nurses. Among the layoffs, 62.5% (15) occurred within the first 3 months, and only 18.75% (3) in the first six and nine months after maternity leave. Conclusions It is possible to conclude that the nursing professional return to work after maternity leave quality requires investment in health policies that promote greater social and labour support.

0292 Comparison of personal habits and baseline knowledge of health promotion among students of the Faculdade de Medicina da Universidade de São Paulo

Objectives Because of the importance given to the implementation of health promotion programs nowadays generating positive outcomes important to society and especially to businesses, employees and the financial market this study was designed to assess students’ baseline knowledge of expertise in occupational medicine on health promotion and correlate it with the students’ baseline knowledge Faculdade de Medicina da Universidade de São Paulo (internal fifth-year residents and first-year internal medicine) as well as evaluate their own health habits. Method We conducted a cross-sectional study in which we applied two questionnaires that had been used in previous studies by Ferreira Junior, 2011. The questionnaires so called 1) “Survey of attitudes and behaviour” and 2) “Questionnaire assessment of knowledge in health promotion.” Regarding the epidemiological data to submit descriptive statistics and Excel filters the table. Results The higher scores among graduate students, were related to nutrition and oral hygiene, both at present as expected in a year. Questions about professional attitude in their 13 items’ scores were higher post-graduate training in the item. In other items, students’ grades and graduation from residency and postgraduate students were equal. When comparing the mean of graduate students called in questionnaire 2, all items showed lower values in relation to the notes of interns and residents. Conclusions The loss in quality of care is undeniable, since there is awareness on the part of the respondents own lack of technical knowledge updated with regard to health promotion that contrasts with the self-perception of adequate training to do so.

0298 Technical Epidemiological Nexus (NTEP) in Brazil: a critic evaluation after 5 years of its application

Objectives A study has been made regarding the 5 years of Technical Epidemiological Nexus’ application, analysing the amounts collected, the number of occupational accidents recognised in the period, the benefits granted and the main diseases recognised as accidentary. Method It has been performed a bibliographic review of the literature, a study of chapters from books, scientific articles published and research on the website of the Social Providence, evaluating the statistic data from 2007 to 2011 and comparing with the last years without the new previdenciary legislation. Results From the application in NTEP for the recognition of accidents and aggravations to workers’ health, the values collected by INSS increased progressively, with an increase of 14.8% in 9 months of 2007. The number of benefits granted rose 4,3%, from 4 million in 2006 to 4.8 million in 2011. With NTEP there has been an increase in the number of pathologies related to occupation recognised by INSS. Of the 653.1 thousands accidents recognised in the year of 2007, 131.6 thousands (20,15%) were recognised by the new rule, without the need of occupational accident communication. The pathologies of the spine (CID M54) and the ones of the shoulder (CID M75) are among the ones of highest incidence as occupational pathologies. Conclusions In the five years applying the technical epidemiological nexus there were increases in levy of the INSS from the number of benefits granted and the recognition of occupational accidents, the pathologies of the shoulder and spine being the highest ones to increase after the new rule.

Risk factors for computer vision syndrome among operators of two call centres in São Paulo, Brazil

Objectives The aim of this study was to estimate the prevalence of Computer Vision Syndrome (CVS) among operators from two call centres located in São Paulo (n=476). Methods and results The symptoms were: visual fatigue (73.9%), “heaviness” in the eyes (68.2%), “burning” eyes (54.6%), tearing (43.9%) and vision impairment (43.5%). Other associations were: being female (OR 2.6, 95% CI 1.6-4.1), lack of recognition during work (OR 1.4, 95% CI 1.1 to 1.8); organisation of work in telemarketing (OR 1.4, 95% CI 1.1 to 1.7) and work demands (OR 1.1, 95% CI 1.0 to 1.3). Conclusions This study showed the importance of organizational characteristics and psychosocial factors at work as related to the presence of CVS in telemarketing operators.
