RESUMO:Demandas psicológicas e controle são dimensões psicossociais que podem gerar alta exigência no trabalho da enfermagem. Este estudo avalia a associação entre demanda psicológica e controle no trabalho e ocorrência de distúrbios psíquicos menores entre trabalhadores de enfermagem. Estudo transversal incluindo 491 trabalhadores de enfermagem de um hospital universitário do Rio Grande do Sul. Para avaliação dos distúrbios psíquicos menores e das dimensões psicossociais, utilizou-se questionário das versões brasileiras do Self-Report questionnaire-20 e do Job Content Questionnaire, no período de março a setembro de 2006. A prevalência de distúrbios psíquicos menores foi 18,7%. Após ajustes por potenciais confundidores, a chance de distúrbios psíquicos menores foi maior (OR=2,76; IC95%: 1,21-6,27) no quadrante de trabalho em alta exigência, quando comparado aos trabalhadores em trabalho de baixa exigência. Considera-se necessária uma gestão organizacional participativa que inclua os trabalhadores no processo de mudanças e melhorias do ambiente laboral, principalmente no que tange às demandas e ao controle no trabalho.

WORKING CONDITIONS AND SOCIAL-DEMOGRAPHIC CHARACTERISTICS RELATED TO THE PRESENCE OF MINOR PSYCHIC DISORDERS IN NURSING WORKERSABSTRACT: Psychological demands and control are psychosocial dimensions of work that may generate high levels of stress in nursing work. This study evaluates the association between psychological demands and control in nursing work and the occurrence of minor psychic disorders among nursing workers. This transversal study includes 491 nursing workers from a university hospital in Rio Grande do Sul, Brazil. In order to evaluate the minor psychic disorders and the psychosocial dimensions, Brazilian versions of the Self-Report questionnaire-20 and the Job Content Questionnaire were used, during the period of March to September of 2006. An 18.7% prevalence of minor psychic disorders was observed . After adjustments for potentially confusing elements, the chance for minor psychic disorders was higher (OR=2.76; IC 95%: 1.21-6.27) in the high demand working quadrant when compared to workers in the low demand working quadrant. We consider it necessary to have organizational and participatory management which includes the workers in the process of changes and improvements in the working environment, mainly those that affect demands and control in work.

This study aimed to evaluate the association between psychological demands and control on work and the occurrence of musculoskeletal disorders among nursing workers. This cross-sectional study involved 491 nursing workers from a University hospital in Rio Grande do Sul. Brazilian versions of the Nordic Musculoskeletal Questionnaire and the Job Content Questionnaire were used. Among the participants, 96.3% reported some pain in any given part of the body last year, 73.1% in the last seven days and 65.8% reported difficulty in their daily routine. The chances of shoulder pain (OR=1.97; CI95%=1.07-3.64), in the thoracic spine (OR=1.83; CI95%=1.02-3.35) and in the ankles (OR=2.05; CI95%=1.05-4.02) were higher in the high work demand quadrant when compared to the low demand quadrant, after adjustments for potentially confusing factors Intervention measures in the organizational structure are needed, redefining demand levels and control at work.

The hospital environment can cause stress and physical problems among these workers, as work demands arise in this place, in which professionals experience different degrees of control over the activities they perform (1) .Among occupational illnesses, musculoskeletal disorders (MSD) are an important public health problem and one of the most severe conditions in occupational health (5) . The main risk factors include: work organization, environmental factors and possible overload on body segments when making certain movements, for example: excessive force to perform some tasks, repetitiveness and inadequate postures (6) .To understand these disorders, besides ergonomics issues, the psychosocial dimensions of the labor context are being analyzed, mainly in Europe, based on a model proposed at the end of the 1970's (3,(7)(8) . That is the twodimensional Demand-Control Model -DCM. In the DCM, it is considered that exhaustion at work is produced by the interaction between high psychological demands and workers' low control over their job activities (1) .Control over work covers issues related to skill use (learning new things, repetitiveness, creativity) and decision authority (ability to make decisions about one's own work, influence in the work group and in management policy) and psychological demand refers to the psychological requirements workers face while performing their tasks (time pressure, concentration level demanded while performing activities, task interruption and need to await activities performed by oth...
