Work organization and Low back pain in nursing personnel

Nursing personnel are at a high risk from occupational low back injury. Work organization has been suggested as one factor playing a part in the aetiology of occupational low back pain. Baseline data for a prospective epidemiology study were gathered by means of a questionnaire. One part of the questionnaire elicited characteristics of work organization, perceived autonomy, the relationship with head nurse and satisfaction in the relationship with co-workers. Information on history of musculoskeletal problems, reported frequency of lifting and personal characteristics was also gathered. Of 787 nursing staff at two acute care hospitals, 154 (19-6%) reported troublesome low back pain occurring within the previous 6 months. From univariate analyses, such characteristics of work organization as shift, type of schedule and primary versus functional nursing were not associated with low back pain. The relationship with head nurse and perceived autonomy of the job also were not related to recent back pain. Recent low back pain was significantly associated with younger age, the job category ‘registered nurse’ and greater satisfaction in relationships with co-workers. These associations were confirmed in multivariate analysis. None of the work organization factors examined, with the exception of satisfaction with co-workers, were associated with back pain in this study. Moreover, the positive association of satisfaction with coworkers suggests that interventions to improve working relationships may not be helpful in prevention programmes. To some extent, these results are susceptible to biases resulting from selective attrition from nursing and selective participation in the study.

Can participatory ergonomics become 'the way we do things in this firm'- The Scandinavian approach to participatory ergonomics

Under the label ‘participatory ergonomics’ the idea of establishing changes in working conditions through participatory approaches has been a central issue within ergonomics. Tools and procedures have been developed and demonstrated beneficial. But how this approach can be established as the way changes are made in firms have only had limited attention. In the Scandinavian countries legislation has, through mandatory joint working environment committees, tried to establish an organizational unit promoting direct participation. Several studies have showed that the intentions of the legislators are not automatically fulfilled, and they have reviled preconditions for more successful acheivement. This opens for many supplementary regulatory strategies to improve activities in firms, but one has been in focus: establishing formalized management systems within occupational health and safety. This strategy may be contrary to the general intentions in the laws. Some of the conditions which must be taken into consideration are discussed.

ICT in higher education: evaluating outcomes for health education

Abstract This paper presents an investigation that examined and compared the effectiveness of collaborative tutorial activities carried out in both web-based and face-to-face learning environments within an undergraduate health education subject. Effectiveness of the different learning environments was measured in terms of observed learning outcomes, analysis of learner interactions and reported perceptions of the learners regarding their experience. Results demonstrated that web-based environments, with embedded collaborative activities, can effectively foster rich learning experiences that result in attaining positive learning outcomes.     

Psychometric properties of the Problematic Internet Use Questionnaire

Several instruments have been designed to measure problems associated with excessive, compulsive, or addictive use of the Internet. One such instrument, the 18-item Problematic Internet Use Questionnaire, was recently published with data supporting a three subscale model (Demetrovics et al., 2008). These researches utilized an online format with a sample taken from the general population of Hungary. We utilized an American college student sample and a paper and pencil format to perform a confirmatory factor analysis of the PIUQ. In addition, we examined the reliability and construct validity of the PIUQ by examining the scales’ relationship with several indices of psychological and physical health. CFA results indicate a barely adequate and not completely problem free three factor model for the PIUQ (χ² = 477.40; root mean square error = .097; comparative fit index = .831; Tucker Lewis coefficient = .804). Cronbach’s α for the total scale was .91 while the Cronbach’s α for each subscale were .81, .77, and .79. Construct validity for the model is demonstrated with significant correlations between the subscales and several indices of psychological and physical health. Suggestions for further research are provided.     

Towards evidence-based guidelines for wise use of computers by children

This paper argues for the systematic development and presentation of evidence-based guidelines for appropriate use of computers by children. The currently available guidelines are characterised and a proposed conceptual model presented. Five principles are presented as a foundation to the guidelines. The paper concludes with a framework for the guidelines, key evidence for and against guidelines, and gaps in the available evidence, with the aim of facilitating further discussion.

Relevance to industry

The current generation of children in affluent countries will typically have over 10 years of computer experience before they enter the workforce. Consequently, the primary prevention of computer-related health disorders and the development of good productivity skills for the next generation of workers needs to occur during childhood.

Developments in Health-Related Quality Standards for Chemicals in Drinking Water

Small differences in water quality standards can mean huge differences in costs for water treatment; difficulties which are compounded by standards for which the derivation is unclear, such as the EC drinking water Directive. Such situations give no indication of the margin of safety for a parameter or the significance to consumers of exceedances. The WHO Guidelines are being revised and will be presented so that the precise derivation of the numbers is absolutely clear. The scientific and quasi-scientific considerations can be separated and the user given the appropriate information to adapt the guidelines to particular circumstances. In deriving standards for toxicological data the factors incorporated reflect uncertainties in the data and extrapolation from animals to man. Understanding the mechanisms of toxicity or carcinogenicity can reduce the uncertainty and improve the quality of the standard, often allowing higher figures to be used with confidence that public health will not be comprised.     

Dampness in buildings and health. Nordic interdisciplinary review of the scientific evidence on associations between exposure to "dampness" in buildings and health effects (NORDDAMP)

Several epidemiological investigations concerning indoor environments have indicated that "dampness" in buildings is associated to health effects such as respiratory symptoms, asthma and allergy. The aim of the present interdisciplinary review is to evaluate this association as shown in the epidemiological literature. A literature search identified 590 peer-reviewed articles of which 61 have been the foundation for this review. The review shows that "dampness" in buildings appears to increase the risk for health effects in the airways, such as cough, wheeze and asthma. Relative risks are in the range of OR 1.4-2.2. There also seems to be an association between "dampness" and other symptoms such as tiredness, headache and airways infections. It is concluded that the evidence for a causal association between "dampness" and health effects is strong. However, the mechanisms are unknown. Several definitions of dampness have been used in the studies, but all seems to be associated with health problems. Sensitisation to mites may be one but obviously not the only mechanism. Even if the mechanisms are unknown, there is sufficient evidence to take preventive measures against dampness in buildings.
