Worksite health programs: working together to advance employee health

Associations between Indoor Environmental Quality and Infectious Diseases Knowledge, Beliefs and Practices of Hotel Workers in Wuhan, China

Knowledge, beliefs, and practices regarding infectious diseases are key elements that ensure practitioners' health and safety. It is important to carry out such a survey in hotels. This study aims to determine the levels of knowledge, beliefs, and practices regarding infectious diseases among practitioners and their associations with the environmental quality of hotels in Wuhan, China. We surveyed infectious disease knowledge, beliefs, and practices of practitioners in 18 hotels and detected these hotels' environment, including physical factors of temperature, humidity, noise, and the indoor air quality of benzene, toluene, xylene, formaldehyde, CO, CO₂, the total count of fungi, aerobic plate count, PM₁₀, and PM_2.5. 128 practitioners were included, and 28.9% were male. The questionnaire included knowledge, beliefs, and practices regarding infectious diseases. Our study found moderate levels of knowledge and beliefs, and good health practices. People's beliefs toward COVID-19 were correlated significantly with their knowledge (p < 0.05). Beliefs and health practices were correlated significantly with environmental quality (p < 0.05). However, the environmental quality was correlated negatively with the classification of hotels. Conclusively, despite the good health practices of practitioners, the knowledge and beliefs toward infectious diseases need to strengthen. Hotels should emphasize health education in practitioners and the improvement of environmental hygiene. Integrating all three components into a comprehensive environmental promotion program is warranted.

Sun Safe Workplaces: Effect of an Occupational Skin Cancer Prevention Program on Employee Sun Safety Practices

OBJECTIVE

Occupational skin cancer prevention is a priority because outdoor workers are exposed to high levels of ultraviolet radiation, the primary risk factor for skin cancer.

METHODS

A 2-year follow-up assessment of the impact of Sun Safe Workplaces (SSW), a workplace sun safety program that promoted policy adoption and education, on employee sun safety behavior was conducted. Sixty-three of 98 local government organizations from the original study participated.

RESULTS

Outdoor workers (n = 1724) completed surveys on personal sun protection practices. Employees' sun protection improved statistically significantly in the intervention group receiving the SSW program. SSW's effect was mediated by the number of workplace actions to implement elements of the policy, including sun protection messages and equipment and employee reports of sun safety training.

CONCLUSION

Policy promotion is a feasible approach to occupational skin cancer prevention.

Development of an Ecological Assessment Tool for a Workplace Physical Activity Program Standard

This project was undertaken to develop a Workplace Physical Activity Assessment Tool to evaluate workplace physical activity programs based on a standard of best practices indicated in the literature and by key stakeholders. The development of the Assessment Tool was structured on an ecological model for health and physical activity promotion and an occupational health and safety audit instrument. The project included a review and synthesis of pertinent literature, expert and stakeholder reviews, interrater reliability appraisals, and workplace consultations over three distinct study phases. The Assessment Tool was received positively by the expert reviewers (i.e., academics, policy makers, and practitioners) and revealed generally high interrater reliability. The Workplace Physical Activity Assessment Tool can be used to plan, implement, and evaluate physical activity programs in the workplace. Recommendations for future research are identified.

Sustained use of an occupational sun safety program in a recreation industry: follow-up to a randomized trial on dissemination strategies

The sustainability of evidence-based programs is needed to obtain long-term benefits. To assess sustainability of Go Sun Smart (GSS), an occupational skin cancer prevention program disseminated to the North American ski industry. Fifty-three of the 68 ski areas from the original dissemination trial participated in 2012 and 2013, 5 to 7 years after program distribution by enhanced or basic dissemination strategies. Sustained use was measured by: (1) on-site observation of sun protection communication and (2) an online survey with senior managers. In the sustainability assessment, sun safety communication had declined, and dissemination strategy did not affect continued use. Managers held weaker attitudes about skin cancer importance and program fit, but more managers provided free/reduced-cost sunscreen than in the dissemination trial. Manager turnover was a key factor in program discontinuance. Sustainability remains a challenge. Additional research is needed to determine the best strategies for sustainability.

Prevention of work-related cancers

Work-related cancers are highly preventable. The primary responsibility for prevention rests not with the workers who are affected by cancers, but with the manufacturers and distributors of carcinogenic substances and the companies who use them. U.S. public policies of strict product liability and the Occupational Safety and Health Act of 1970 address the issue of responsibility. Workers, health care providers, and others also have important roles that complement employers' preventive efforts. The range of prevention strategies available includes ones that should be applied to prevent potentially carcinogenic substances from being marketed and distributed; others that apply in the workplace where potential carcinogens are used; and public policy interventions aimed at ensuring universal implementation of pre-market and workplace prevention strategies. Work-related cancer remains a large problem, even though strategies exist to identify carcinogens and prevent and control on-the-job exposures. However, preventive efforts by government and the society have stalled and a continuing lack of toxicity information shows inadequate societal commitment. The principal barriers to prevention of work-related cancers are political and economic rather than scientific and medical.

Improving the prevention and control of hazardous substance exposures: a randomized controlled trial in manufacturing worksites

BACKGROUND

New measures of exposure prevention (EP) activity were used to evaluate the effectiveness of a 16-month management-focused intervention addressing hazardous substance exposures in manufacturing work settings.

METHODS

EP efforts were assessed using a rating scheme developed for this study. The rating scheme yields a set of measures of exposure potential and protection, which are combined into an overall EP summary rating. A randomized, controlled design was used to assess intervention effectiveness. Fifteen large manufacturing worksites completed the 16-month intervention and follow-up assessments. Analyses were conducted on the 107 production processes assessed at both baseline and final.

RESULTS

Patterns of improvement within the intervention condition were consistent with the intervention emphasis on upstream or source-focused intervention; whereas patterns in controls were consistent with prevalent practice (more downstream, worker-focused). A mixed model analysis of variance showed greater improvement in EP ratings in intervention versus controls, but the difference in improvement was moderate and statistically non-significant.

CONCLUSIONS

This study has demonstrated that EP efforts in the manufacturing sector can be systematically assessed across the full range of hazardous substances in use, and that such assessments can serve both needs assessment and effectiveness evaluation functions. Findings suggest that more sustained or intense management-focused intervention would significantly improve EP activity in manufacturing settings.

Assessing and intervening on OSH programmes: effectiveness evaluation of the Wellworks-2 intervention in 15 manufacturing worksites

AIMS

(1) To develop a transparent and broadly applicable method for assessing occupational safety and health (OSH) programmes or management systems; (2) to assess OSH programmes in a sample of manufacturing worksites; and (3) to determine whether a management focused occupational health intervention results in greater improvement in OSH programmes compared to minimal intervention controls.

METHODS

OSH programmes were assessed using an adaptation of the US Occupational Safety & Health Administration's 1995 Program Evaluation Profile. Scores were generated from 91 binary indicator variables grouped under four "Essential Elements". Essential Element scores were weighted to contribute to an overall programme score on a 100 point scale. Seventeen large manufacturing worksites were assessed at baseline; 15 sites completed the 16 month intervention and follow up assessments.

RESULTS

There was considerable variation in Essential Element scores across sites at baseline as judged by our instrument, particularly in "management commitment and employee participation" and "workplace analysis". Most sites scored highly on "hazard prevention and control" and "training and education". For overall OSH programme scores, most sites scored in the 60-80% range at baseline, with four sites scoring below 60%, suggesting weak programmes. Intervention sites showed greater improvements than controls in the four programme elements and in overall programme scores, with significantly greater improvements in "management commitment and employee participation".

CONCLUSIONS

The OSH programme assessment method used is broadly applicable to manufacturing work settings, and baseline profiles suggest needs for improvement in OSH programmes in most such worksites. Despite a small sample size, results showed that sustained management focused intervention can result in improvement in these OSH programme measures.

Worker-trainers as evaluators: a case study of a union-based health and safety education program

The United Automobile Workers uses worker-trainers to deliver health and safety education training to its members. The union has experimented with worker-trainers participating in program evaluation. Worker-trainers participated in the design and conduct of a telephone survey of training impact, and of an on-site survey of trainee perceptions of a large-scale program. Worker evaluators were able to analyze data and give a highly successful presentation of results to trainees at the large-scale program. The incorporation of workers as evaluators is a key step toward the goal of worker empowerment. The involvement of program participants in their program's evaluation can enhance the quality and usefulness of work-site health and safety programs in general.

The influence of self-efficacy and outcome expectations on the relationship between perceived environment and physical activity in the workplace

BACKGROUND: Recent research and commentary contends that ecological approaches may be particularly useful for understanding and promoting physical activity participation in various settings including the workplace. Yet within the physical activity domain there is a lack of understanding of how ecological environment factors influence behaviour. Thus, the purpose of this study was to examine the relationships between perceived environment, social-cognitive variables, and physical activity behaviour. METHODS: Participants (N = 897) were employees from three large worksites who completed self-report inventories containing measures of self-efficacy, outcome expectations, perceptions of the workplace environment (PWES), and physical activity behaviour during both leisure-time and incorporated throughout the workday. RESULTS: Results of both bivariate and multiple regression analyses indicated the global PWES scores had a limited association with leisure-time physical activity (R2adj =.01). Sequential regression analyses supported a weak association between physical activity incorporated in the workplace and PWES (R2adj =.04) and the partial mediation of self-efficacy on the relationship between PWES and workplace physical activity (variance accounted for reduced to R2adj =.02 when self-efficacy was controlled). CONCLUSION: Overall, the results of the present investigation indicate that self-efficacy acted as a partial mediator of the relationship between perceived environment and workplace physical activity participation. Implications of the findings for physical activity promotion using ecological-based approaches, and future directions for research from this perspective in worksite settings are discussed.

Pesticides in Lebanon: a knowledge, attitude, and practice study

Pesticides, despite their known toxicity, are widely used in developing countries. Evaluating the pattern of their use would be interesting to assess the appropriateness of adequate intervention. Using a standardized questionnaire, a knowledge, attitude, and practice study was performed in two Lebanese regions, in which a group of agricultural workers was compared to workers of the general population and a third group of pesticide distributors. Agricultural workers were exposed to pesticides during cropping, mixing, loading, and application (100%). They had low pesticide knowledge scales compared to pesticide distributors and to the general population workers (P<10(-7)). The preventive measures they took were low, and the lower their knowledge was, the lower were the preventive measures applied (P<10(-3)). Pesticide safety education is necessary in order to induce protective behavior among agricultural workers. The general population may also benefit from increasing their awareness regarding pesticides.

Comprehensive Health Promotion Interventions at the Workplace: Experiences With Health Circles in Germany

Health circles, the central element of a comprehensive health promotion approach that has been developed in Germany in recent years, emphasize organizational and psychosocial factors while actively involving employees in the process. Through an extensive review the authors identified 11 studies, presenting the results of 81 health circles. The scientific quality of the data is limited: only 3 studies used (nonrandomized) control groups, whereas the remaining studies are based on retrospective before-and-after comparison. Nonetheless, the available data suggest that health circles are an effective tool for the improvement of physical and psychosocial working conditions and have a favorable effect on workers' health, well-being, and sickness absence. More rigorous studies are needed to confirm these results.

A review and analysis of the clinical and cost-effectiveness studies of comprehensive health promotion and disease management programs at the worksite: 1995-1998 update (IV)

The fourth in a series of critical reviews, this study examines the clinical and cost outcome evaluations of 10 worksite health promotion programs that were comprehensive, multifactorial, and directed at risk management. The studies, conducted between 1994 and 1998, indicate favorable clinical and cost outcomes and suggest characteristics of worksite interventions that may be critical for effectiveness.

The effects of a health promotion-health protection intervention on behavior change: the WellWorks Study

OBJECTIVES

This study assessed the effects of a 2-year integrated health promotion-health protection work-site intervention on changes in dietary habits and cigarette smoking.

METHODS

A randomized, controlled intervention study used the work site as the unit of intervention and analysis; it included 24 predominantly manufacturing work sites in Massachusetts (250-2500 workers per site). Behaviors were assessed in self-administered surveys (n = 2386; completion rates = 61% at baseline, 62% at final). Three key intervention elements targeted health behavior change: (1) joint worker-management participation in program planning and implementation, (2) consultation with management on work-site environmental changes, and (3) health education programs.

RESULTS

Significant differences between intervention and control work sites included reductions in the percentage of calories consumed as fat (2.3% vs 1.5% kcal) and increases in servings of fruit and vegetables (10% vs 4% increase). The intervention had a significant effect on fiber consumption among skilled and unskilled laborers. No significant effects were observed for smoking cessation.

CONCLUSIONS

Although the size of the effects of this intervention are modest, on a populationwide basis effects of this size could have a large impact on cancer-related and coronary heart disease end points.

Clinical and cost outcomes of multifactorial, cardiovascular risk management interventions in worksites: a comprehensive review and analysis

This paper is a critical review of the clinical and cost outcome evaluation studies of multifactorial, comprehensive, cardiovascular risk management programs in worksites. A comprehensive international literature search conducted under the auspices of the National Heart, Lung and Blood Institute identified 17 articles based on 12 studies that examined the clinical outcomes of multifactorial, comprehensive programs. These articles were identified through MEDLINE, manual searches of recent journals, and through direct inquiries to worksite health promotion researchers. All studies were conducted between 1978 and 1995, with 1978 being the date of the first citation of a methodologically rigorous evaluation. Of the 12 research studies, only 8 utilized the worksite as both the unit of assignment and as the unit of analysis. None of the studies analyzed adequately for cost effectiveness. Given this limitation, this review briefly considers the relevant worksite research that has demonstrated cost outcomes. Worksite-based, multifactorial cardiovascular intervention programs reviewed for this article varied widely in the comprehensiveness, intensity, and duration of both the interventions and evaluations. Results from randomized trials suggest that providing opportunities for individualized, cardiovascular risk reduction counseling for high-risk employees within the context of comprehensive programming may be the critical component of an effective worksite intervention. Despite the many limitations of the current methodologies of the 12 studies, the majority of the research to date indicates the following: (1) favorable clinical and cost outcomes; (2) that more recent and more rigorously designed research tends to support rather than refute earlier and less rigorously designed studies; and (3) that rather than interpreting the methodological flaws and diversity as inherently negative, one may consider it as indicative of a robust phenomena evident in many types of worksites, with diverse employees, differing interventions, and varying degrees of methodological sophistication. Results of these studies reviewed provide both cautious optimism about the effectiveness of these worksite programs and insights regarding the essential components and characteristics of successful programs.

A review of health-related outcomes of multi-component worksite health promotion programs

PURPOSE

The purpose of this article is to critically review evaluation studies of the health-related effects (i.e., health risk modification and reduction in worker absenteeism) of multicomponent worksite health promotion programs.

SEARCH METHOD

A comprehensive literature search conducted under the auspices of the Centers for Disease Control and Prevention identified 36 articles that examined health-related outcomes of multi-component programs. The authors identified 11 additional articles through manual searches of recent journal issues and through personal contacts with worksite health promotion researchers. Forty-seven studies describing the results of 35 worksite health promotion programs were reviewed.

IMPORTANT FINDINGS

The worksite health promotion programs reviewed for this article varied tremendously in the comprehensiveness, intensity, and duration of the intervention activities. All of the programs provided health education to employees. In a majority of the programs, opportunities to learn and practice new skills were also offered. A smaller number of programs incorporated modifications in organizational policy or the physical work environment. Results from well-conducted randomized trials suggest that providing opportunities for individual risk reduction counseling for high risk employees within the context of comprehensive programming may be the critical component of an effective worksite health promotion program. Just offering low intensity, short duration programs aimed at increasing awareness of health issues for the entire employee population may not be sufficient to achieve desired outcomes.

MAJOR CONCLUSIONS

The results of the studies reviewed provide both cautious optimism about the effectiveness of these worksite programs and some general guidance as to the critical components and characteristics of successful programs. Overall, the evidence suggests that a rating of indicative/acceptable may best characterize this literature.
