Using formative research to develop environmental and ecological interventions to address overweight and obesity

Barriers and facilitative factors in the implementation of workplace health promotion activities in small and medium-sized enterprises: a qualitative study

Background

There is an immense difference between large companies and small and medium-sized enterprises (SMEs) in implementation of evidence-based interventions (EBIs). Previous literature reveals various barriers that SMEs face during implementation, such as a lack of time, accessibility, and resources. However, few studies have comprehensively examined those influential factors at multi-levels. This study aims to identify the factors influencing the implementation of non-communicable disease prevention activities (tobacco, alcohol, diet, physical activity, and health check-up) in SMEs using Consolidated Framework for Implementation Research (CFIR).

Methods

We conducted 15 semi-structured interviews with health managers and/or employers in 15 enterprises with less than 300 employees, and four focus groups among public health nurses/nutritionists of health insurers who support SMEs in four prefectures across Japan. A qualitative content analysis by a deductive directed approach was performed. After coding the interview transcript text into the CFIR framework constructs by two independent researchers, the coding results were compared and revised in each enterprise until an agreement was reached.

Results

Of the 39 CFIR constructs, 25 were facilitative and 7 were inhibitory for workplace health promotion implementation in SMEs, which were across individual, internal, and external levels. In particular, the leadership engagement of employers in implementing the workplace health promotion activities was identified as a fundamental factor which may influence other facilitators, including “access to knowledge and information,” “relative priority,” “learning climate,” at organizational level, and “self-efficacy” at the health manager level. The main barrier was the beliefs held by the employer/manager that “health management is one’s own responsibility.”

Conclusions

Multi-level factors influencing the implementation of non-communicable diseases prevention activities in SMEs were identified. In resource-poor settings, strong endorsement and support, and positive feedback from employers would be important for health managers and employees to be highly motivated and promote or participate in health promotion. Future studies are needed to develop context-specific strategies based on identified barriers and facilitative factors, and empirically evaluate them, which would contribute to narrowing the differences in worksite health promotion implementation by company size.

Factors influencing the implementation of workplace health promotion in companies in rural areas

Purpose

Workplace health promotion (WHP) is becoming increasingly important due to the ageing workforce and a shortage of skilled workers. Nevertheless, too few companies have reacted to the demographic change and introduced health-promoting measures. This paper aims to identify which factors influence the implementation of WHP, especially in small and medium-sized enterprises (SMEs) in rural areas.

Design/methodology/approach

253 companies in a rural area in the federal state of Saxony (Germany) were surveyed using a standardised questionnaire via a computer-assisted telephone interview. Bivariate analyses and logistic regression models were carried out. The focus was on the relationship between the status of WHP and the size of the company, pressure of demographic change, health-related attitude and organisational capacity factors.

Findings

It was shown that, in addition to the control variables company size and pressure of the shortage of skilled workers, a company's attitude regarding health promotion, financial capacity and planning and development capacity has a relevant influence on the status of WHP.

Practical implications

Based on the results, targeted measures can be developed and converted to implement WHP, particularly in SMEs in rural regions. The focus should be on sensitisation, knowledge transfer and capacity development.

Originality/value

The present paper reveals the relationship between company size, pressure of demographic change, health-related attitude and organisational capacities regarding the status of health-promoting measures in SMEs in a rural region.

Strategies to improve the implementation of workplace-based policies or practices targeting tobacco, alcohol, diet, physical activity and obesity

BACKGROUND

Given the substantial period of time adults spend in their workplaces each day, these provide an opportune setting for interventions addressing modifiable behavioural risk factors for chronic disease. Previous reviews of trials of workplace-based interventions suggest they can be effective in modifying a range of risk factors including diet, physical activity, obesity, risky alcohol use and tobacco use. However, such interventions are often poorly implemented in workplaces, limiting their impact on employee health. Identifying strategies that are effective in improving the implementation of workplace-based interventions has the potential to improve their effects on health outcomes.

OBJECTIVES

To assess the effects of strategies for improving the implementation of workplace-based policies or practices targeting diet, physical activity, obesity, tobacco use and alcohol use.Secondary objectives were to assess the impact of such strategies on employee health behaviours, including dietary intake, physical activity, weight status, and alcohol and tobacco use; evaluate their cost-effectiveness; and identify any unintended adverse effects of implementation strategies on workplaces or workplace staff.

SEARCH METHODS

We searched the following electronic databases on 31 August 2017: CENTRAL; MEDLINE; MEDLINE In Process; the Campbell Library; PsycINFO; Education Resource Information Center (ERIC); Cumulative Index to Nursing and Allied Health Literature (CINAHL); and Scopus. We also handsearched all publications between August 2012 and September 2017 in two speciality journals: Implementation Science and Journal of Translational Behavioral Medicine. We conducted searches up to September 2017 in Dissertations and Theses, the WHO International Clinical Trials Registry Platform, and the US National Institutes of Health Registry. We screened the reference lists of included trials and contacted authors to identify other potentially relevant trials. We also consulted experts in the field to identify other relevant research.

SELECTION CRITERIA

Implementation strategies were defined as strategies specifically employed to improve the implementation of health interventions into routine practice within specific settings. We included any trial with a parallel control group (randomised or non-randomised) and conducted at any scale that compared strategies to support implementation of workplace policies or practices targeting diet, physical activity, obesity, risky alcohol use or tobacco use versus no intervention (i.e. wait-list, usual practice or minimal support control) or another implementation strategy. Implementation strategies could include those identified by the Effective Practice and Organisation of Care (EPOC) taxonomy such as quality improvement initiatives and education and training, as well as other strategies. Implementation interventions could target policies or practices directly instituted in the workplace environment, as well as workplace-instituted efforts encouraging the use of external health promotion services (e.g. gym membership subsidies).

DATA COLLECTION AND ANALYSIS

Review authors working in pairs independently performed citation screening, data extraction and 'Risk of bias' assessment, resolving disagreements via consensus or a third reviewer. We narratively synthesised findings for all included trials by first describing trial characteristics, participants, interventions and outcomes. We then described the effect size of the outcome measure for policy or practice implementation. We performed meta-analysis of implementation outcomes for trials of comparable design and outcome.

MAIN RESULTS

We included six trials, four of which took place in the USA. Four trials employed randomised controlled trial (RCT) designs. Trials were conducted in workplaces from the manufacturing, industrial and services-based sectors. The sample sizes of workplaces ranged from 12 to 114. Workplace policies and practices targeted included: healthy catering policies; point-of-purchase nutrition labelling; environmental supports for healthy eating and physical activity; tobacco control policies; weight management programmes; and adherence to guidelines for staff health promotion. All implementation interventions utilised multiple implementation strategies, the most common of which were educational meetings, tailored interventions and local consensus processes. Four trials compared an implementation strategy intervention with a no intervention control, one trial compared different implementation interventions, and one three-arm trial compared two implementation strategies with each other and a control. Four trials reported a single implementation outcome, whilst the other two reported multiple outcomes. Investigators assessed outcomes using surveys, audits and environmental observations. We judged most trials to be at high risk of performance and detection bias and at unclear risk of reporting and attrition bias.Of the five trials comparing implementation strategies with a no intervention control, pooled analysis was possible for three RCTs reporting continuous score-based measures of implementation outcomes. The meta-analysis found no difference in standardised effects (standardised mean difference (SMD) -0.01, 95% CI -0.32 to 0.30; 164 participants; 3 studies; low certainty evidence), suggesting no benefit of implementation support in improving policy or practice implementation, relative to control. Findings for other continuous or dichotomous implementation outcomes reported across these five trials were mixed. For the two non-randomised trials examining comparative effectiveness, both reported improvements in implementation, favouring the more intensive implementation group (very low certainty evidence). Three trials examined the impact of implementation strategies on employee health behaviours, reporting mixed effects for diet and weight status (very low certainty evidence) and no effect for physical activity (very low certainty evidence) or tobacco use (low certainty evidence). One trial reported an increase in absolute workplace costs for health promotion in the implementation group (low certainty evidence). None of the included trials assessed adverse consequences. Limitations of the review included the small number of trials identified and the lack of consistent terminology applied in the implementation science field, which may have resulted in us overlooking potentially relevant trials in the search.

AUTHORS' CONCLUSIONS

Available evidence regarding the effectiveness of implementation strategies for improving implementation of health-promoting policies and practices in the workplace setting is sparse and inconsistent. Low certainty evidence suggests that such strategies may make little or no difference on measures of implementation fidelity or different employee health behaviour outcomes. It is also unclear if such strategies are cost-effective or have potential unintended adverse consequences. The limited number of trials identified suggests implementation research in the workplace setting is in its infancy, warranting further research to guide evidence translation in this setting.

Managers’ Support for Employee Wellness Programs: An Integrative Review

Objective:

The aim of this integrative literature review is to synthesize the existing evidence regarding managers’ support for employee wellness programs.

Data Source:

The search utilized multiple electronic databases and libraries.

Study Inclusion and Exclusion Criteria:

Inclusion criteria comprised peer-reviewed research published in English, between 1990 and 2016, and examining managers’ support in the context of a worksite intervention. The final sample included 21 articles for analysis.

Data Extraction:

Two researchers extracted and described results from each of the included articles using a content analysis.

Data Synthesis:

Two researchers independently rated the quality of the included articles. Researchers synthesized data into a summary table by study design, sample, data collected, key findings, and quality rating.

Results:

Factors that may influence managers’ support include their organization’s management structure, senior leadership support, their expected roles, training on health topics, and their beliefs and attitudes toward wellness programs and employee health. Managers’ support may influence the organizational culture, employees’ perception of support, and employees’ behaviors.

Conclusions:

When designing interventions, health promotion practitioners and researchers should consider strategies that target senior, middle, and line managers’ support. Interventions need to include explicit measures of managers’ support as part of the evaluation plan.

We can do that! Collaborative assessment of school environments to promote healthy adolescent nutrition and physical activity behaviors

Evidence for effectiveness of school-based studies for prevention of adolescent obesity is equivocal. Tailoring interventions to specific settings is considered necessary for effectiveness and sustainability. The PRECEDE framework provides a formative research approach for comprehensive understanding of school environments and identification of key issues/areas to focus resources and energies. No reported studies have tested applicability of the PRECEDE framework in schools in relation to obesity. Adolescents (n = 362), parents (n = 349) and teachers (n = 146) from six secondary schools participated in two quantitative studies and two qualitative studies. Data collected from these studies permitted confirmation of adolescent overweight/obesity a health issue for schools; the need for secondary schools to focus health promotion efforts on healthy nutrition, with inclusion of parents/homes and appreciation for gender differences in developing interventions. Community buy-in and commitment to school-based obesity prevention programs may be dependent on initially addressing what may be perceived as minor issues, and developing policies to guide practices within schools in relation to supply and access to healthy foods, use of sporting equipment and participation in physical activities. The PRECEDE framework allows systematic assessment of school environments and provided opportunity to identify realistic and relevant interventions for promoting healthy adolescent physical activity and nutrition behaviors.

How needs and preferences of employees influence participation in health promotion programs: a six-month follow-up study

Background

Low participation in health promotion programs (HPPs) might hamper their effectiveness. A potential reason for low participation is disagreement between needs and preferences of potential participants and the actual HPPs offered. This study aimed to investigate employees’ need and preferences for HPPs, whether these are matched by what their employers provide, and whether a higher agreement enhanced participation.

Methods

Employees of two organizations participated in a six-month follow-up study (n = 738). At baseline, information was collected on employees’ needs and preferences for the topic of the HPP (i.e. physical activity, healthy nutrition, smoking cessation, stress management, general health), whether they favored a HPP via their employer or at their own discretion, and their preferred HPP regarding three components with each two alternatives: mode of delivery (individual vs. group), intensity (single vs. multiple meetings), and content (assignments vs. information). Participation in HPPs was assessed at six-month follow-up. In consultation with occupational health managers (n = 2), information was gathered on the HPPs the employers provided. The level of agreement between preferred and provided HPPs was calculated (range: 0–1) and its influence on participation was studied using logistic regression analyses.

Results

Most employees reported needing a HPP addressing physical activity (55%) and most employees preferred HPPs organized via their employer. The mean level of agreement between the preferred and offered HPPs ranged from 0.71 for mode of delivery to 0.84 for intensity, and was 0.47 for all three HPP components within a topic combined. Employees with a higher agreement on mode of delivery (OR: 1.72, 95% CI: 0.87-3.39) and all HPP components combined (OR: 2.36, 95% CI: 0.68-8.17) seemed to be more likely to participate in HPPs, but due to low participation these associations were not statistically significant.

Conclusion

HPPs aimed at physical activity were most needed by employees. The majority of employees favor HPPs organized via the employer above those at their own discretion, supporting the provision of HPPs at the workplace. This study provides some indications that a higher agreement between employees’ needs and preferences and HPPs made available by their employers will enhance participation.

Changing the Food Environment for Obesity Prevention: Key Gaps and Future Directions

The food environment has a great impact on the nutritional health of the population. Food environment interventions have become a popular strategy to address the obesity epidemic. However, there are still significant gaps in our understanding of the most effective strategies to modify the food environment to improve health. In this review, we examine key gaps in the food environment intervention literature, including the need for: developing appropriate formative research plans when addressing the food environment; methods for selecting intervention domains and components; incorporating food producers and distributors in intervention strategies; strengthening evaluation of environmental interventions; building the evidence base for food environment interventions in diverse settings; engaging policy makers in the process of modifying the food environment; and creating systems science models to examine the costs and benefits of a potential program or policy on the food environment prior to implementation. In addition, we outline the need for strategies for addressing these issues including conducting additional pilot interventions, developing additional methodologies, and embracing the use of simulation models.

What is actually measured in process evaluations for worksite health promotion programs: a systematic review

Background

Numerous worksite health promotion program (WHPPs) have been implemented the past years to improve employees’ health and lifestyle (i.e., physical activity, nutrition, smoking, alcohol use and relaxation). Research primarily focused on the effectiveness of these WHPPs. Whereas process evaluations provide essential information necessary to improve large scale implementation across other settings. Therefore, this review aims to: (1) further our understanding of the quality of process evaluations alongside effect evaluations for WHPPs, (2) identify barriers/facilitators affecting implementation, and (3) explore the relationship between effectiveness and the implementation process.

Methods

Pubmed, EMBASE, PsycINFO, and Cochrane (controlled trials) were searched from 2000 to July 2012 for peer-reviewed (randomized) controlled trials published in English reporting on both the effectiveness and the implementation process of a WHPP focusing on physical activity, smoking cessation, alcohol use, healthy diet and/or relaxation at work, targeting employees aged 18-65 years.

Results

Of the 307 effect evaluations identified, twenty-two (7.2%) published an additional process evaluation and were included in this review. The results showed that eight of those studies based their process evaluation on a theoretical framework. The methodological quality of nine process evaluations was good. The most frequently reported process components were dose delivered and dose received. Over 50 different implementation barriers/facilitators were identified. The most frequently reported facilitator was strong management support. Lack of resources was the most frequently reported barrier. Seven studies examined the link between implementation and effectiveness. In general a positive association was found between fidelity, dose and the primary outcome of the program.

Conclusions

Process evaluations are not systematically performed alongside effectiveness studies for WHPPs. The quality of the process evaluations is mostly poor to average, resulting in a lack of systematically measured barriers/facilitators. The narrow focus on implementation makes it difficult to explore the relationship between effectiveness and implementation. Furthermore, the operationalisation of process components varied between studies, indicating a need for consensus about defining and operationalising process components.

Young people's participation in the development of a self-care intervention--a multi-site formative research study

The poor outcomes of young people with chronic health conditions indicate that current services and self-care programmes are not meeting the needs of young people. How young people self-manage their condition impacts on long-term health outcomes, but there is little published evidence that details the development of self-care programmes and their most effective components. This article reports on an innovative formative research study, the purpose of which was to develop a self-care intervention prototype. Participants were 87 young people, aged 12-17, and seven young adult facilitators, aged 18-25, with type 1 diabetes or asthma. Each contributed to talking groups exploring themes that young people wanted to be addressed within a self-care programme. Instead of being focused on 'illness', young people's main concerns were directed toward 'life as an adolescent', while at the same time building sustainable daily routines of self-care. Overall, this article illustrates the process of initiating and implementing a developmental approach focused on young people, while also demonstrating the tailored self-care intervention that the process developed. This approach can be used to involve young people in the design and development of other conditions that rely on self-care interventions.

Designing in the social context: using the social contextual model of health behavior change to develop a tobacco control intervention for teachers in India

This article provides a theory-based, step-by-step approach to intervention development and illustrates its application in India to design an intervention to promote tobacco-use cessation among school personnel in Bihar. We employed a five-step approach to develop the intervention using the Social Contextual Model of Health Behavior Change (SCM) in Bihar, which involved conducting formative research, classifying factors in the social environment as mediating mechanisms and modifying conditions, developing a creative brief, designing an intervention and refining the intervention based on pilot test results. The intervention engages users and non-users of tobacco, involves teachers in implementing and monitoring school tobacco control policies and maximizes teachers' role as change agents in schools and communities. Intervention components include health educator visits, discussions led by lead teachers, cessation assistance, posters and other educational materials and is implemented over the entire academic year. The intervention is being tested in Bihar government schools as part of a randomized-controlled trial. SCM was a useful framework for developing a tobacco control intervention that responded to teachers' lives in Bihar.

Process evaluation results from an environmentally focused worksite weight management study

There is currently much interest in exploring environmental approaches to combat weight gain and obesity. This study presents process evaluation results from a workplace-based study that tested two levels of environmentally focused weight management interventions in a manufacturing setting. The moderate treatment featured a set of relatively simple, low-cost environmental modifications designed to facilitate healthy eating and physical activity; the intense treatment added elements intended to actively involve and engage management in program efforts. Fidelity varied across the 11 interventions comprising the two treatment conditions but did not vary systematically by treatment condition (moderate vs. intense). Environmental assessments showed improvements in workplace supports for weight management and significant differences by treatment level. Positive shifts in health climate perceptions also occurred, but sites receiving the intense treatment were not perceived as more supportive by employees. Challenges and limitations associated with environmental interventions are discussed with specific reference to activating management support.

Process evaluation of an environmental walking and healthy eating pilot in small rural worksites

Small Steps are Easier Together (SS) was a pilot environmental intervention in small rural worksites in Upstate New York in collaboration with Extension educators. Worksite leaders teamed with co-workers to select and implement environmental changes to increase walking steps over individual baseline and to choose healthy eating options over 10 weeks. Participants were 226 primarily white, women employees in 5 sites. A mixed methods process evaluation, conducted to identify determinants of intervention effectiveness and to explain differences in outcomes across worksites, included surveys, self-reports of walking and eating, interviews, focus groups, and an intervention log. The evaluation assessed reach, characteristics of recruited participants, dose delivered, dose received, and context and compared sites on walking and eating outcomes. Emergent elements of participant-reported dose received included: active leadership, visible environmental changes, critical mass of participants, public display of accomplishments, accountability to co-workers, and group decision making. Participants at sites with high reach and dose were significantly more likely than sites with low reach and dose to achieve intervention goals. Although this small pilot needs replication, these findings describe how these evaluation methods can be applied and analyzed in an environmental intervention and provide information on trends in the data.

Combining environmental and individual weight management interventions in a work setting: results from the Dow chemical study

OBJECTIVE

To evaluate the comparative effectiveness of environmental weight loss interventions alone versus in combination with an individual intervention.

METHODS

A quasi-experimental design compared outcomes for two levels of environmental interventions and for participants who did or did not simultaneously self-select into an individually focused weight loss intervention (YW8). Analysis of covariance and logistic regression techniques were used to examine risk outcomes.

RESULTS

Employees who participated in YW8 were no more successful at losing weight than those exposed to only the environmental interventions. Approximately, 13.5% of each group lost at least 5% of their body weight; overall changes in mean body weight and body mass index were negligible in both groups.

CONCLUSIONS

Simple worksite environmental modifications may help with weight maintenance, but are not likely to result in substantial weight reductions even when combined with low-intensity individual interventions.

Management support of workplace health promotion: field test of the leading by example tool

PURPOSE

This study tested a repeated-measures application of the Leading by Example (LBE) questionnaire, a self-report instrument measuring organizational leadership support for health promotion.

DESIGN

The efficacy of the LBE was tested in a quasi-experimental health promotion intervention trial. Twelve worksites were assigned to three intervention conditions (i.e., control, moderate, high intensity).

SETTING

The worksites were selected from a large U.S.-based chemical company.

SUBJECTS

Baseline data were collected from employees in various job roles in 2005 (N  =  125). Follow-up data were collected in 2006 (N  =  114) and 2007 (N  =  106). Response rates ranged from 54% to nearly three-fourths of potential respondents.

INTERVENTION

Worksites assigned to both treatment conditions received changes in the built environment via supports for weight management. Worksites assigned to the intense condition received additional elements designed to impact leadership's support for a positive health promotion climate.

MEASURES

Four LBE factors measuring management support for health were assessed over time.

ANALYSIS

The Kruskal-Wallis H-test and analyses of variance/covariance were used to compare LBE scores.

RESULTS

Significant changes from baseline to 2006 were identified for the four factors (p  =  .000) of the LBE. No significant changes were found from 2006 to 2007.

CONCLUSIONS

The LBE effectively captured perceptions of management support for health. Researchers and practitioners alike should consider using the LBE to track and evaluate perceptions of management support for health promotion.

Second-year results of an obesity prevention program at the Dow Chemical Company

OBJECTIVE

Evaluate innovative, evidence-based approaches to organizational/supportive environmental interventions aimed at reducing the prevalence of obesity among Dow employees after 2 years of implementation.

METHODS

A quasi-experimental study design compared outcomes for two levels of intervention intensity with a control group. Propensity scores were used to weight baseline differences between intervention and control subjects. Difference-in-differences methods and multilevel modeling were used to control for individual and site-level confounders.

RESULTS

Intervention participants maintained their weight and body mass index, whereas control participants gained 1.3 pounds and increased their body mass index values by 0.2 over 2 years. Significant differences in blood pressure and cholesterol values were observed when comparing intervention employees with controls. At higher intensity sites, improvements were more pronounced.

CONCLUSIONS

Environmental interventions at the workplace can support weight management and risk reduction after 2 years.

Environmental assessment at worksites after a multilevel intervention to promote activity and changes in eating: the PACE project

OBJECTIVE

To evaluate changes in the worksite environment in response to a multilevel intervention over a 2-year period.

METHODS

Worksites were recruited in the greater Seattle area, and 34 were randomized to intervention or comparison condition. The intervention was based on the ecological model, with a framework of defined phases of intervention that included worksite-wide events implemented in partnership with employee-based advisory boards. The assessment of the worksite environment used a modification of the Checklist of Health Promotion Environments at Worksites. Subscales were developed using baseline data only. The intervention effect on different aspects of the worksite environment was estimated using logistic regression with robust estimating procedures.

RESULTS

Only changes in the physical activity and nutrition information environments were significantly associated with the intervention.

CONCLUSIONS

This article provides one of the first attempts at using environmental assessment in the evaluation of worksite interventions.

Obesity and Food Choices Among Faculty and Staff at a Large Urban University

OBJECTIVE

in order to address increasing health care costs associated with obesity, this study sought to determine prevalence of overweight and obesity and examine eating behaviors, food choices, health beliefs, and attitudes of university employees.

PARTICIPANTS AND METHODS

an online survey was distributed to > 3,800 faculty and staff at a large public metropolitan university in Winter 2008.

RESULTS

almost half (48%) of 806 respondents were classified as overweight or obese. Compared to those with normal weights, overweight and obese respondents consumed fewer fruits and vegetables (p < .05), were less confident in making healthful food choices (p < .001), and were more influenced by food choices available in on-campus dining facilities (p < .05).

CONCLUSIONS

obesity among university employees warrants attention. Because these employees have less self-efficacy and consume less healthful diets than their normal weight colleagues, universities need to improve on-campus access to healthful foods.

How accurate are self-reports? Analysis of self-reported health care utilization and absence when compared with administrative data

OBJECTIVE

To determine the accuracy of self-reported health care utilization and absence reported on health risk assessments against administrative claims and human resource records.

METHODS

Self-reported values of health care utilization and absenteeism were analyzed for concordance to administrative claims values. Percent agreement, Pearson's correlations, and multivariate logistic regression models examined the level of agreement and characteristics of participants with concordance.

RESULTS

Self-report and administrative data showed greater concordance for monthly compared with yearly health care utilization metrics. Percent agreement ranged from 30% to 99% with annual doctor visits having the lowest percent agreement. Younger people, males, those with higher education, and healthier individuals more accurately reported their health care utilization and absenteeism.

CONCLUSIONS

Self-reported health care utilization and absenteeism may be used as a proxy when medical claims and administrative data are unavailable, particularly for shorter recall periods.

Formative research in occupational health and safety intervention for diverse, underserved worker populations: a homecare worker intervention project

OBJECTIVE

The increasing numbers of minority, low-income, and contingent workers in the U.S. labor force present new challenges to occupational safety and health interventions. Formative research can be used to help researchers better understand target populations and identify unanticipated barriers to safety changes. The National Institute for Occupational Safety and Health initiated an intervention project to improve health and safety among homecare workers in Alameda County, California. Investigators conducted systematic formative research to gather information to guide intervention development.

METHODS

Various qualitative methods were used including 11 focus groups (conducted in English, Spanish, and Chinese) and 10 key informant interviews. This article focuses on two picture-based focus group activities that explored workers' views on their relationships with consumers and their perceived barriers to interventions.

RESULTS

Findings indicated cultural differences regarding workers' perceptions of their relationships with consumers. Chinese homecare workers mostly focused on respecting elders rather than initiating changes. Some English- and Spanish-speaking workers described efforts to negotiate with consumers. Results also identified workers' perceived barriers to interventions, such as consumers' resistance to changes and lack of resources. These findings played important roles in shaping the intervention materials. For example, given the lack of resources among consumers, the project tried to tap into community-level resources by collaborating with local stakeholders and developing community resource guides.

CONCLUSION

Formative research can be a valuable step to inform the development of occupational health and safety interventions for diverse, underserved worker populations.

Addressing obesity in the workplace: the role of employers

CONTEXT

Employers have pursued many strategies over the years to control health care costs and improve care. Disappointed by efforts to manage costs through the use of insurance-related techniques (e.g., prior authorization, restricted provider networks), employers have also begun to try to manage health by addressing their employees' key lifestyle risks. Reducing obesity (along with tobacco use and inactivity) is a priority for employers seeking to lower the incidence and severity of chronic illness and the associated demand for health services.

METHODS

This article describes the employer's perspective on the cost impact of obesity, discusses current practices in employer-sponsored wellness and weight management programs, provides examples from U.S. companies illustrating key points of employers' leverage and opportunities, and suggests policy directions to support the expansion of employers' initiatives, especially for smaller employers.

FINDINGS

Researchers and policymakers often overlook the extensive efforts and considerable impact of employer-sponsored wellness and health improvement programs. Greater focus on opportunities in the workplace is merited, however, for the evidence base supporting the economic and health impacts of employer-sponsored health promotion and wellness is growing, although not as quickly as the experience base of large employers.

CONCLUSIONS

Public and private employers can serve their own economic interests by addressing obesity. Health care organizations, particularly hospitals, as well as public employers can be important role models. Policy development is needed to accelerate change, especially for smaller employers (those with fewer than 500 employees), which represent the majority of U.S. employers and are far less likely to offer health promotion programs.

First-year results of an obesity prevention program at The Dow Chemical Company

OBJECTIVE

To examine first-year results from a workplace environmental obesity prevention program at The Dow Chemical Company.

METHODS

A quasi-experimental cohort study was conducted among employees at nine treatment worksites (n = 8013) who received environmental weight management interventions and three control worksites (n = 2269). Changes in employees' weight, body mass index (BMI), and other health risks were examined using chi2 and t-tests.

RESULTS

After 1 year, a modest treatment effect was observed for weight and BMI largely because the control group subjects gained weight; however, no effect was observed for overweight and obesity prevalence. Other risk factors (tobacco use, high blood pressure, and systolic and diastolic blood pressure values) decreased significantly, although blood glucose (high risk prevalence and values) increased.

CONCLUSIONS

Environmental changes to the workplace can achieve modest improvements in employees' health risks, including weight and BMI measures, in 1 year.

Development of the Environmental Assessment Tool (EAT) to measure organizational physical and social support for worksite obesity prevention programs

OBJECTIVE

To describe the development, reliability, and validity of the Environmental Assessment Tool (EAT) for assessing worksite physical and social environmental support for obesity prevention.

METHODS

The EAT was developed using a multistep process. Inter-rater reliability was estimated via Kappa and other measures. Concurrent and predictive validity were estimated using site-level correlations and person-level multiple regression analyses comparing EAT scores and employee absenteeism and health care expenditures.

RESULTS

Results show high inter-rater reliability and concurrent validity for many measures and predictive validity for absenteeism expenditures.

CONCLUSIONS

The primary use of the EAT is as a physical and social environment assessment tool for worksite obesity prevention efforts. It can be used as a reliable and valid means to estimate relationships between environmental interventions and absenteeism and medical expenditures, provided those expenditures are for the same year that the EAT is administered.
