Resumo: Introdução: Os computadores são parte da vida moderna e seu uso deles massificado; diariamente as pessoas passam várias horas diante de uma tela pelas diversas facilidades no trabalho, no lazer, na conectividade, entre outros. Ao mesmo tempo também trazem riscos à saúde de seus usuários, sendo descritos problemas psicológicos, problemas musculoesqueléticos e problemas visuais; estes últimos apresentam uma alta prevalência (50%-70%) e os sintomas visuais e oculares, que trazem incômodos para realização de atividades com o computador, reduzem a produtividade dos trabalhadores e diminuem a qualidade de vida dos usuários de computadores. Estes efeitos à saúde visual têm sido pouco estudados pela comunidade científica. Objetivos: Levantar a frequência de casos da Síndrome da Visão do Computador em professores universitários e identificar os fatores de risco associados à presença da CVS. Metodologia: Trata-se de estudo de tipo transversal observacional e participam professores de uma universidade pública do Estado de São Paulo; foram aplicados dois questionários, um versando sobre aspectos do trabalho e do uso de computadores e outro, sobre sintomas oculares e visuais. Além disso, foram realizados exames visuais. A coleta de dados foi feita entre os meses de Fevereiro a Dezembro de 2013 no campus da universidade. Critérios de Inclusão: Professores da universidade. Critérios de Exclusão: Professores que não usem o computador. Resultados: Em uma amostra de 53 professores a Síndrome da Visão do Computador foi encontrada em 30 professores, 19 deles classificados com a forma leve da Síndrome, 10 com a moderada e 1 com a severa; os sintomas que mais incomodaram os professores foram fadiga (30 participantes), ressecamento ocular (20 participantes), irritação ocular (17 participantes). Foram encontrados problemas binoculares em 27 dos 53 professores e diminuição na produção lacrimal em 12/53. Conclusões: Os professores universitários são uma população com uma alta prevalência da Síndrome da Visão do computador, na amostra apresentou-se a síndrome em mais da metade dos participantes 30/23(56%), concordando assim com as prevalências da Síndrome encontradas nos estudos internacionais. Três variáveis foram associadas significativamente ao aparecimento da CVS nos professores universitários, a idade que minimiza as chances de ter CVS (OR: 0,91 IC: 0,83/0,97 P-value: 0,015), as horas de uso diárias no computador que aumentam as chances de apresentar CVS (OR: 1,26 IC: 1,05/1,57 P-value: 0,021), e os problemas vergenciais como insuficiência ou excesso de convergência ou divergência, os quais estão associados positivamente com o aparecimento da síndrome (OR: 3,24 IC: 1,06/10,49 P-value: 0,042).

Abstract: Computers are part of modern life, their use sprayed and people spend several hours using them as they bring several facilities in work, leisure, connectivity, among others. Computers also brought risks to the health of its users, psychological problems, musculoskeletal problems and visual problems, although the latter with a high prevalence (50% -70%) and with visual and ocular symptoms that diminish the quality of life of users, bother working with the computer and reduce worker productivity, has been little studied by the scientific community. Objectives: The study aims to estimate the cases frequency of the Computer Vision Syndrome in teachers and to identify risk factors associated with the presence of CVS. Methodology: This is a cross-sectional-observational study with teachers of a public university which two questionnaires and a visual test is performed to find and evaluate the possible symptoms of Computer Vision Syndrome of as well as their associated factors. The survey is conducted between the months of February to December 2013 at the University campus. Inclusion Criteria: Teachers and researchers at university. Exclusion Criteria: Teachers and researches that do not use the computer. Results: In a sample of 53 teachers of Computer Vision Syndrome was found in 30 teachers, 19 were classified as mild form of the syndrome, 10 with moderate and 1 with severe, the symptoms that bother the teachers were fatigue (30 participants), ocular dryness (20 participants), eye irritation (17 participants). Binocular problems were found in 27 of the 53 teachers and decrease in tear production in 12/53. Conclusions: The teachers are a population with a high prevalence of the Computer Vision Syndrome, the sample presented the syndrome in more than half of the participants 30/23 (56%), thus agreeing with the prevalence of the syndrome found in international studies. Three variables were significantly associated with 5 % with the onset of CVS on university teachers , the age that minimizes the chances of having CVS (OR: 0.91 IC: 0.83/0.97 P-value: 0.015), hours daily use of the computer that increase the chances of presenting CVS (OR: 1.26 IC: 1.05/1.57 P-value: 0.021), and vergenciais problems like deficiency or excess of convergence or divergence, which are positively associated with the onset of the syndrome (OR: 3.24 IC: 1.06/10.49 P-value: 0.042). Keywords: Computer Vision Syndrome, asthenopia, video display terminals, ergonomics, occupational health

Texto completoENGLISH ABSTRACT: Aims: To assess the effect of a vertical height adjustment of the chair and visual display unit (VDU) on work related upper quadrant musculoskeletal pain (WRUQMP) and sitting comfort in computer users. The upper quadrant refers to the occiput, cervical and upper thoracic spine including the clavicles and scapulae. Methods: An N=1 study was conducted using the ABC design whereby an ergonomic workstation adjustment, of VDU and chair height, was compared to the subject’s usual workstation settings. Pain and sitting comfort were measured using visual analogue scales (VAS). The subject was assessed over the four week phases as she performed her typical VDU work. The results were compiled and tabulated. Results: Both the mean and variance in pain intensity decreased after the workstation intervention. A deterioration was noted in sitting comfort. Conclusion: The vertical height adjustment of the chair and VDU may have contributed to a decrease in WRUQMP in this subject. This safe, economical workstation intervention may be a practical management option for the computer user suffering from WRUQMP. Further research into the measurement of comfort whilst sitting at a computer workstation, is recommended.
AFRIKAANSE OPSOMMING: Doelwitte: Om die effek te bepaal van n vertikale aanpassing van die stoel en beeldskerm van rekenaargebruikers op werksverwandte boonste kwadrant muskuloskeletale pyn en sitgemak. Die boonste kwadrant verwys na die oksiput, servikale en boonste torakale werwelkolom en sluit ook die klavikel en skapula in. Methode: Die N=1 studie is onderneem met gebruik van die ABC ontwerp in terme waarvan n ergonomiese aanpassing van stoel en beeldskerm vergelyk is met die normale gebruik van die deelnemer. Pyn en sitgemak is gemeet deur die gebruik van die Visueel analoogskaal. Die interwensies is ge-evalueer oor vierweekfases tydens normale rekenaar gebruik van die deelnemer. Die resultate is saamgestel en getabuleer. Uitkoms: Beide die gemiddelde en veranderlike pynintensiteit het verminder nadat die werkstasie aangepas is. Geen verbetering in sitgemak is opgemerk nie. Gevolgtrekking: Die vertikale hoogte-aanpassing van die stoel en beeldskerm het moontlik bygedra tot die verminderde pynvlakke in hierdie deelnemer. Hierdie veilige, ekonomiese verstelling is moontlik n praktiese beheeropsie vir rekenaargebruikers wat werksverwandte boonste kwadrant muskuloskeletale pyn verduur. Verder studie in die meet en waarneming van sitgemak tydens rekenaarwerk is nodig.

Texto completoENGLISH ABSTRACT: Aims: To assess the effect of a chair and computer screen height adjustment on the neck and upper back musculoskeletal symptoms in an office worker. Methods: An N=1 study was conducted using the ABC design. Ethics approval was obtained for the study and the participant provided informed written consent. The participant was assessed over three four week phases as she performed her habitual computer work. The outcome measures assessed during the three phases were the pain intensity and perceived sitting comfort. The three phases were named the baseline, intervention and wash-out phases. During the baseline phase, the outcome measures were obtained at the participant‟s habitual work station. The intervention phase involved a vertical adjustment of the chair and computer screen height. The wash-out phase allowed the participant to adjust the chair and computer screen height to their choice. A follow-up interview was conducted with the participant three months after completion of the study. The mean values and the ranges of the pain intensity and perceived comfort were obtained and compared. The data collected was captured on a Microsoft Excel 2010 spread sheet, where after the data was tabulated and presented graphically. Results: The mean pain intensity of the participant increased slightly during the intervention phase in comparison to the baseline phase, but remained stable during the wash-out phase. The mean perceived sitting comfort deteriorated initially during the intervention phase, but improved later during the intervention phase and showed greater improvement during the wash out phase. The perceived sitting comfort showed more improvement than the pain intensity during the washout phase. Both the pain intensity and perceived sitting comfort showed improvement at the three months follow up assessment, post completion of the study. Conclusion: The vertical height adjustment of the chair and the VDT did not improve the participant‟s pain intensity and perceived sitting comfort when compared to the participant‟s habitual workstation parameters. The findings do not favour the horizontal viewing angle. The findings of this study however support the use of „slightly below horizontal‟ viewing angle as being conducive to reduce the pain intensity and improve the sitting comfort of an office worker.
AFRIKAANSE OPSOMMING: Doelstelling: Om die effek te bepaal van die hoogte aanpassing van die stoel en rekenaarskerm op die nek en bo-rug muskuloskeletale simptome van 'n kantoorwerker. Metodes: „n N=1 studie was uitgevoer deur gebruik te maak van die ABC ontwerp. Etiese goedkeuring was verkry vir die studie en die deelnemer het ingeligte skriftelike toestemming verleen. Die deelnemer was ge-evalueer oor drie vier week-lange fases terwyl sy haar gewone rekenaarwerk verrig het. Die uitkomsmetings ge-evalueer tydens die drie fases was pyn intensiteit en waargenome sitgemak. Die drie fases was genoem die basislyn, intervensie en uitwas fases. Gedurende die basislyn fase was die uitkomsmetings by die deelnemer se gewone werkstasie ingevorder. Die intervensie fase het 'n vertikale aanpassing van die stoel en rekenaarskerm behels. Die uitwas fase het die deelnemer toegelaat om haar stoel en rekenaarskerm se hoogte aan te pas volgens haar keuse. 'n Opvolg onderhoud was gevoer met die deelnemer drie maande na die voltooiing van die studie. Die resultate was vasgelê op 'n Microsoft Excel 2010 data bladsy, waarna die data getabuleer en grafies uitgebeeld is. Resultate: Die gemiddelde pyn intensiteit van die deelnermer het effens toegeneem tydens die intervensie fase in vergelyking met die basislyn fase, maar het stabiel gebly tydens die uitwas fase. Die gemiddelde waargenome sitgemak het aanvanklik verswak tydens die intervensie fase, maar het later verbeter tydens die intervensie fase en het aangehou verbeter tydens die uitwas fase. Die waargenome sitgemak het groter verbetering getoon as die pyn intensiteit tydens die uitwas fase. Beide pyn intensiteit en waargenome sitgemak het verbetering getoon by die drie maande opvolg evaluasie, na voltooiing van die studie. Gevolgtrekking. Die vertikale hoogte aanpassing van die stoel en rekenaarskerm het nie die deelnemer se pyn intensiteit en waargenome sitgemak in vergelyking met die deelnemer se gewone werkstasie parameters verbeter nie. Hierdie bevindinge is nie ten voordeel van die horisontale kykhoek nie. Nietemin, ondersteun die bevindinge van hierdie studie die gebruik van die "effens onder die horisontale" kykhoek as bevorderend om die pyn intensiteit te verminder en die sitgemak van 'n kantoorwerker te verbeter.

Using a visual display terminal (VDT) is today a common occupational task with both benefits and hazards. Some of the potential health hazards were the occurrence of asthenopia, musculoskeletal and psychosomatic disorders. In the field study of 101 VDT group and 206 reference group in three hospitals from the south Taiwan, surveying medical and workplace investigation as well as questionnaires, we can obtain the prevalence rates, odd ratios and relevant risk factors. The results of our study are: (1) the prevalence rates of VDT users in asthenopia, musculoskeletal and psychosomatic disorders are 56%, 83% and 24% respectively. (2) the odds ratios(95%C.I.) compared with reference group in asthenopia, musculoskeletal disorder (including symptoms and sign) are 2.54 (95% C.I. 1.56~4.12), 4.11(95%C.I. 2.34~7.23) and 2.61(95% C.I. 1.56~4.12) respectively. And there is no statistical difference in psychosomatic disorder. (3) By the analysis of logistic regression, the relevant risk factors are: VDT work, work stress index, working time, working place and hypermobility of fingers. In conclusion, the prevalences of asthenopia and musculoskeletal disorders of VDT worker are high. And there is more work to do in the fields of health care and occupational preventive medicine.
