    Intervention in a hospital foodservice and its effects on musculoskeletal symptoms
    (2011) ISOSAKI, Mitsue; CARDOSO, Elisabeth; GLINA, Debora Miriam Raab; PUSTIGLIONE, Marcelo; ROCHA, Lys Esther
    Objective This study analyzed the working conditions of a hospital food service before and after ergonomic interventions and their impact on the prevalence of work-related musculoskeletal symptoms. Methods This case study was performed in a public heart hospital in Sao Paulo, Brazil with 115 workers. The data were collected by questionnaires and ergonomic analysis of the work before and after the intervention. The data were statistically analyzed by the software SPSS 13.0 and Excel 2003 to verify symptom prevalence before and after the interventions. Results The workers were female nutrition attendants aged 25-34 years, with secondary education, married, with children. Most of the problems regarded limited space, inappropriate equipment and work materials, inadequate number of workers, intense mental effort and high prevalence of musculoskeletal symptoms, mainly in the lower limbs and shoulders. Once the working conditions improved, musculoskeletal symptoms decreased and all workers noted the changes made to the physical environment, equipment and work organization. Conclusion The interventions promoted improvements in the work environment and equipment and reduced the musculoskeletal symptoms experienced in the lower limbs, shoulders, neck, forearm and lower back, although this reduction was not statistically significant.

    Risk factors for computer visual syndrome (CVS) among operators of two call centers in Sao Paulo, Brazil
    (2012) SA, Eduardo Costa; FERREIRA JUNIOR, Mario; ROCHA, Lys Esther
    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 two call centers' operators in Sao Paulo (n = 476). 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). The operators were mainly female and young (from 15 to 24 years old). The call center was opened 24 hours and the operators weekly hours were 36 hours with break time from 21 to 35 minutes 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%. Associations verified were: being female (OR 2.6, 95% CI 1.6 to 4.1), lack of recognition at work (OR 1.4, 95% CI 1.1 to 1.8), organization of work in call center (OR 1.4, 95% CI 1.1 to 1.7) and high demand at work (OR 1.1, 95% CI 1.0 to 1.3). The organization and psychosocial factors at work should be included in prevention programs of visual syndrome among call centers' operators.

    Participatory ergonomics: Understanding the contributions of reflection groups in a hospital food service
    (2011) GLINA, Debora Miriam Raab; CARDOSO, Adriana S.; ISOSAKI, Mitsue; ROCHA, Lys E.
    Aim: To identify how the methodology of Reflection Groups (RG) can contribute to approach social-psychological problems, so often observed as obstacles in PE efforts. The objective was also to verify the contributions from RG to the implementation of ergonomics recommendations, which were a starting point and organized group discussions. Method: A concrete case was used as an illustration, and studied in depth: RG with administration and production workers' representatives from the Department of Nutrition and Dietetics of a cardiologic hospital in Sao Paulo, Brazil. RG are temporary thinking groups, taking place outside the workplace and having delegative and consultive participation. They make use of Operative Groups, an adapted form of tripartite group, activity as an instrumental resource, group dynamic techniques and videotaping. In 2007, 31 meetings took place during paid working hours with 7 groups of different composition, ranging from 1.5 h to 3 h. Results: Additionally to the positive effects in communication and psychosocial environment, RG could also contribute to changes in interpersonal relationships, cooperation, personal and work behaviours. By dealing with aspects which could hinder the explicit task: fears, conflicts, and stereotyped beliefs and behaviours; resistance to change could be broken and group members could learn. RG allowed input about new risks; continuous information and feedback about ongoing ergonomics interventions so that immediate corrective action could be taken. The main form of participation was in administrative, organizational, and psychosocial problems which required a better clarification and identification of their real causes, commitment, and elaboration of strategies and negotiation of different stakeholders in their solution. Conclusion: RG takes advantage of homogeneous and heterogeneous groups, in face to face communication. The interactions in the groups are task-oriented (explicit task) but attaining groups' goals depends on a relational interaction (implicit task). Relevance to industry: Reflection groups can bring important contributions to ergonomics and industry because they favour the discussion, disclosure of problems and incorporation of solutions, enabling interventions in working organization, psychosocial environment and relationships in a collective and participatory approach, promoting health and social integration.
