Chronic pain,pain severity and analgesia use in Australian women of reproductive age

Background

The increasing prevalence and adverse outcomes associated with opioid analgesia use in women of reproductive age have become a significant public health issue internationally, with use during pregnancy potentially affecting maternal and infant health outcomes.

Developing a Subject-Derived Terminology to Describe Perceptions of Chemicals in Foods

Risk perception may be influenced by a number of factors, such as unfamiliarity, lack of control, perceived consequences, and hazards being seen as catastrophic and having risk for future generations. Risk perception researchers have typically used such investigator-selected characteristics to assess hazards. In the first study reported here, the repertory grid method was used to elicit the terminology that subjects ( n = 30) use to distinguish between 30 different chemicals. The data were submitted to generalized Procrustes analysis. The first principal axis of the resulting consensus plot separated the chemicals ranging from "poisonous or toxic,""harmful or dangerous," and "sounds negative" at one end, to "positive effect on health,""often present in food nowadays," and "sounds positive" at the other end. The second principal axis ranged from "familiar with or knowledge of" and "chemical" to "natural." A second study ( n = 226) was carried out to look at the general validity of the results of the repertory grid interviews using a fixed questionnaire. The data were submitted to principal components analysis and internal preference mapping. The first principal component ranged from "safe" and "healthy" at one end, to "poisonous" and "harmful" at the other end. The chemicals also separated in terms of "familiar,""chemical," and "natural." All three methods of data collection and analysis yield essentially similar results.     

Associations between overtime and psychological health in high and low reward jobs

This study focused on the relationship between overtime and psychological health in high and low reward jobs, and in jobs with high and low external pressure to work overtime. Data were collected for 535 full-time employees of the Dutch Postal Service. In general, overtime was associated with negative work-home interference and negative home-work interference. Split-sample logistic regression analyses showed that employees reporting low rewards had elevated risks of burnout, negative work-home interference and slow recovery. In addition, the combination of overtime and low rewards was associated with negative home-work interference. A second analysis was conducted separately for employees who reported overtime in order to study the effects of external pressure to work overtime. In this subgroup, low rewards were associated with elevated risks of health complaints, emotional exhaustion and negative home-work interference. Moreover, employees who reported overtime and a high pressure to work overtime in combination with low rewards had elevated risks of poor recovery, cynicism, and negative work-home interference. The results suggest that even a limited number of hours of involuntary overtime is associated with adverse mental health, but only in low reward situations.     

Evidence-based exposure criteria for work-related musculoskeletal disorders as a tool to assess physical job demands

Despite worldwide attention, musculoskeletal disorders (MSDs) remain a substantial concern at work. To support ergonomists to assess the work-related risk factors for MSDs, several instruments are available. Unfortunately, many of these instruments are not supported by evidence-based exposure criteria for particular MSDs. For effective prevention of MSDs, it is important to know to what extent work-related risk factors are present in the work situation. The Netherlands Center for Occupational Diseases (NCOD) develops evidence-based criteria documents for the assessment of work-related MSDs. The exposure criteria of these documents can be used on a group level to support ergonomists in their assessment of the physical job demands that are associated with work-related MSDs. At the moment the NCOD has exposure criteria for the assessment of 22 work-related MSDs, for instance on the work-relatedness of upper extremity disorders, non-specific low back pain or patellar tendinopathy. The use of these exposure criteria enables ergonomist to better assess the work-related risks of MSDs as a starting point for effective prevention.     

Singlehood

This study reports some of the results of an inquiry into objective social isolation and feelings of loneliness in a stratified sample of 556 adults (unmarried, divorced, widowed, and married men and women). Given a recent marked increase in the number of singles in the Netherlands, special attention is paid to the single respondents. The results of this study give evidence that unmarried, divorced, and widowed people are, on the average, lonelier than married people. Within the subgroup of unmarried and divorced people living alone, some men and women were found who could be described as “creative singles.” The analysis shows that “creative singles” seem to be able to cope with their situation of living alone. For example, they report few feelings of loneliness, in contrast to the situation of the rest of the group of people living alone.
