Occupational injury in the United Arab Emirates: epidemiology and prevention.

BACKGROUND The United Arab Emirates (UAE) is developing rapidly, with many foreign construction, farm and industrial workers. AIMS To assess the epidemiology of occupational injury hospitalizations using a trauma registry. METHODS Surgical admissions from March 2003 to April 2005 were recorded in the registry at the main trauma hospital in Al Ain city (population 348,000). Prevention-related variables were analysed using SPSS and severity was quantified by injury severity scores (ISS). RESULTS There were 614 occupational injury hospitalizations, an incidence of approximately 136/100,000 workers/year. Males accounted for 98% of injuries, the 25-44 age group for 69% and non-nationals for 96%. External causes included falls 51%, falling objects 15%, powered machines 11%, animal-related 7% and burns 6%. Median ISS was 4 for all six main external causes. Extremities were most frequently injured, followed by chest, head and neck, abdomen and face. Mean hospitalization duration was 9.4 days, with 36% hospitalized for >1 week. CONCLUSIONS The main external causes were proportionately much more frequent than in industrialized countries. Effective countermeasures are needed to reduce the incidence and severity of occupational injury among vulnerable migrant workers in the UAE.

Psychosocial risk assessment in organizations: Concurrent validity of the brief version of the Management Standards Indicator Tool

The Management Standards Indicator Tool (MSIT) is a 35-item self-report measure of the psychosocial work environment designed to assist organizations with psychosocial risk assessment. It is also used in work environment research. Edwards and Webster presented a 25-item version of the MSIT based on the deletion of items having a factor loading of < .65. Stress theory and research suggest that psychosocial hazard exposures may result in harm to the health of workers. Thus, using data collected from three UK organizations (N = 20,406) we compared the concurrent validity of the brief and full versions of the MSIT by exploring the strength of association between each version of the instrument and a measure of psychological wellbeing (GHQ-12 and Maslach Burnout Inventory). Analyses revealed that the brief instrument offered similar but not always equal validity to that of the full version. The results indicate that use of the brief instrument, which would be less disruptive for employees, would not elevate the risk of false negative or false positive findings in risk assessment.

The impact of two workplace-based health risk appraisal interventions on employee lifestyle parameters, mental health and work ability: results of a randomized controlled trial

Health risk appraisals (HRA) are a common type of workplace health promotion programme offered by American employers. In the United Kingdom, evidence of their effectiveness for promoting health behaviour change remains inconclusive. This randomized controlled trial examined the effects of two HRA interventions on lifestyle parameters, mental health and work ability in a UK context. A total of 180 employees were randomized into one of three groups: Group A (HRA augmented with health promotion and education activities), Group B (HRA only) and Group C (control, no intervention). After 12 months, changes in mean scoring in 10 lifestyle, mental health and work ability indices were compared, Groups A and B demonstrated non-significant improvements in 70% and 80%, respectively, compared with controls (40%). Odds ratios revealed that, compared with the control group, Group A was 29.2 (95% CI: 9.22-92.27) times more likely to report a perceived change in lifestyle behaviour; Group B 4.4 times (95% CI: 1.65-11.44). In conclusion, participation in the HRA was associated with a higher likelihood of perceived lifestyle behaviour change which was further increased in the augmented HRA group, thereby providing preliminary evidence that HRA and augmented HRA in particular may help UK employees make positive healthy lifestyle changes.
