FUEL Your Life: A Translation of the Diabetes Prevention Program to Worksites

Twelve-Month Reach and Effectiveness of a University-Based Diabetes Prevention Initiative

INTRODUCTION

The University of California (UC) implemented the Diabetes Prevention Program (DPP) to address diabetes and obesity risk. This project examined the reach and effectiveness of this university-based DPP delivery approach.

METHODS

This project compared 12-month weight change among three groups of UC beneficiaries with overweight/obesity: (1) those who received invitation letters and enrolled in UC DPP, (2) those mailed invitation letters but did not enroll, and (3) those who were not mailed letters and did not enroll (controls). Using 2012-2022 EHR, administrative and DPP cohort data, an interrupted time series was conducted in 2022-2023 to compare group differences in rate of weight change.

RESULTS

Among 6,231 beneficiaries (132 UC DPP aware enrollees, 1,750 DPP aware non-enrollees, 4,349 controls), UC DPP enrollees were older (mean age 49), mostly women (76%), and more diverse (33% Asian, 8% Black, 20% Hispanic, 4% Multi/Other). Over 12 months of follow-up, UC DPP enrollee postenrollment rate of weight loss was -0.68 lbs./month. UC DPP enrollees had significantly greater weight change from pre- to post-enrollment than DPP aware non-enrollees (adjusted Δ-1.02 vs. Δ-0.07 lbs./month, difference= -0.95, p<0.001). Weight change among all participants who received letters with/without DPP enrollment was similar to controls.

CONCLUSIONS

UC DPP reached a diverse group and was effective for weight loss at 12-month follow-up. However, UC DPP invitation letters to raise prediabetes and DPP awareness were not associated with significant weight change in the absence of DPP enrollment. University-based approaches to DPP delivery are effective and may enhance reach of DPP among at-risk adults.

Diet Quality Outcomes of a Cooperative Extension Diabetes Prevention Program

OBJECTIVE

The effectiveness of the National Diabetes Prevention Program (DPP) in improving diet quality (DQ) in community settings is largely unknown. This study aimed to evaluate the DQ changes of Extension DPP participants.

METHODS

A single-group, repeated-measures design was used to evaluate an Extension-implemented DPP using the PreventT2 curriculum. Participants were overweight adults with or at high risk for prediabetes (n = 88). Weight and DQ (Healthy Eating Index-2015, Dietary Screener Questionnaire) were evaluated using mixed-effects regression.

RESULTS

There was no change in the Healthy Eating Index-2015 total score. Predicted fiber, fruit, and vegetable intake increased (P < 0.05) but remained below recommendations.

CONCLUSIONS AND IMPLICATIONS

Clinically meaningful DQ changes of Extension DPP participants were limited. The effect of the DPP on DQ in Extension and other implementation settings should be evaluated through randomized controlled trials. Diabetes Prevention Program curriculum revisions that include more specific dietary goals and educational tools may promote greater DQ changes in DPP participants.

Translation of a family-based behavioral intervention for adolescent obesity using the RE-AIM framework and common steps from adaptation frameworks

Interventions for adolescent weight management that are ready to use in clinical settings are needed to address the obesity epidemic and improve the health and wellbeing of affected adolescents. This report describes the systematic process our team followed to adapt an evidence-based intervention (EBI) for adolescent weight management from its randomized control trial protocol to a package for delivery in a group-based telehealth format within a medical center. The EBI adaptation was clinician initiated, prompted by identified practice needs, and involved collaboration of the clinical team with the EBI developer. The process was guided by the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework and followed key steps for adapting EBIs to new contexts. RE-AIM-aligned adaptations included telehealth delivery and broader inclusion criteria, separate clinical and research evaluation batteries, adaptations to fit the clinical practice, practical fidelity checklists to guide and record session delivery, and continuous quality improvement processes aimed to facilitate program longevity and family engagement. The process culminated in a package of adapted intervention materials deemed by stakeholders as appropriate to the practice and congruent with the EBI model. This report provides a much-needed practical demonstration of the translation of an EBI for adolescent weight management from research protocol to group telehealth delivery in a medical center. Key lessons include the value of clinician-researcher collaboration, the breadth of resources needed to adapt EBIs for real-world delivery, and the importance of considering delivery context in implementation and evaluation decisions, including defining inclusion criteria, staffing, and outcomes assessments.

Using Community Health Workers to Address Barriers to Participation and Retention in Diabetes Prevention Program: A Concept Paper

Objective:

The PreventionLink of Southern Maryland is a 5-year project to eliminate barriers to participation and retention in the National Diabetes Prevention Program (DPP) lifestyle change program to prevent or delay the onset of type 2 diabetes in adults with prediabetes. This is the study to identify the obstacles to participation and retention in the DPP lifestyle change program among high burden populations and learn how CHWs have reduced the identified barriers to participation and retention for high burden populations.

Methods:

We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) to conduct this literature review. We have used the Scopus and PubMed, including all types of studies and peer-reviewed documents published in English between 2010 and 2020.

Results:

From 131 identified articles, 18 articles were selected for qualitative synthesis. The reviewed literature documented following as main barriers to participate in a DPP lifestyle change program: time, cost, lack of transportation, cost of transportation, commute distance, technology access, access to facilities and community programs, caregiver responsibilities, lack of health literacy and awareness, and language. CHWs can address these barriers to participation and retention, they were involved in educating and supporting roles; they worked as bridges between healthcare providers and participants and as intervention team members.

Conclusions:

Diabetes prevention program participants with social determinant risk factors who most need CHW services are unlikely to have financial resources to pay for CHW services out-of-pocket. Hence, the public and private health plans that pay for their prediabetes care should consider paying for these CHW services and there is a need to trust more to CHW and have them as a “community health teams” member.

Behavioural interventions for CVD risk reduction for blue-collar workers: a systematic review

OBJECTIVES

Individuals working in blue-collar occupations experience high rates of cardiovascular disease (CVD). The purpose of this systematic review is to describe the characteristics and efficacy of behavioural interventions that have targeted CVD risk factors in this high-risk group.

METHODS

Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we searched seven databases to find interventions focused on changing the following: blood pressure, cholesterol, diet, physical activity, smoking or weight. Eligible studies tested a behavioural intervention (not exclusively policy, environmental, or pharmaceutical), in individuals working in blue-collar occupations using a randomised study design. Study quality was evaluated using the National Heart, Lung, and Blood Institute's study quality assessment tool.

RESULTS

22 studies evaluating 31 interventions were included: 11 were rated as 'good' or 'fair' quality. Intervention intensity ranged from a single contact via a mailed letter to studies that included individual-level contacts at multiple time points between staff and participants. Studies that included at least some individual contact generally yielded the greatest effects. Interventions had the greatest observed effects on self-report changes in diet, regardless of intervention intensity. Four of the five higher quality studies that explicitly tailored the intervention to the occupational group were successful at reducing at least one risk factor.

CONCLUSIONS

Interventions that used individual contact and tailored the intervention to the occupational setting yielded the greatest effects on CVD risk-factor reduction in individuals working in blue-collar occupations. Generally, studies were low quality but showed promising effects for reaching this high-risk population. Future work should incorporate these promising findings in higher quality studies.

Evaluation of the University of California Diabetes Prevention Program (UC DPP) Initiative

Background

Type 2 diabetes can negatively impact long term health outcomes, healthcare costs and quality of life. However, intensive lifestyle interventions, including the Diabetes Prevention Program (DPP), can significantly lower risk of incident type 2 diabetes among overweight adults with prediabetes. Unfortunately, the majority of adults in the US who are at risk of developing diabetes do not engage in DPP-based lifestyle change programs. Increased adoption of evidence-based obesity and diabetes prevention interventions, such as the DPP, may help large employers reduce health risks and improve health outcomes among employees. In 2018, the University of California Office of thePresident (UCOP) implemented the UC DPP Initiative, a novel, multi-component program to address diabetes and obesity prevention across the UC system.

Methods

The goal of our study is to conduct a multifaceted evaluation of the UC DPP Initiative using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework. Our evaluation will integrate unique and diverse UC data sources, including electronic health record (EHR) data, administrative claims, campus-based DPP cohort data, qualitative interviews and site visits. Our primary outcome of interest is the mean percent weight change among three groups of overweight/obese UC beneficiaries at risk for diabetes at 12-month follow-up. Secondary outcomes include mean percent weight change at 24-month follow-up, barriers and facilitators associated with implementatio, as well as  the degree of program adoption and maintenance.

Discussion

Our study will help inform diabetes and obesity prevention efforts across the UC system. Findings from this evaluation will also be highly applicable to universities and large employers, as well as community organizers, healthcare organizations and insurers implementing the DPP and/or other health promotion interventions.

Effectiveness of workplace wellness programmes for dietary habits, overweight, and cardiometabolic health: a systematic review and meta-analysis

Background

The workplace offers a unique opportunity for effective health promotion. We aimed to comprehensively study the effectiveness of multicomponent worksite wellness programmes for improving diet and cardiometabolic risk factors.

Methods

We did a systematic literature review and meta-analysis, following PRISMA guidelines. We searched PubMed-MEDLINE, Embase, the Cochrane Library, Web of Science, and Education Resources Information Center, from Jan 1, 1990, to June 30, 2020, for studies with controlled evaluation designs that assessed multicomponent workplace wellness programmes. Investigators independently appraised the evidence and extracted the data. Outcomes were dietary factors, anthropometric measures, and cardiometabolic risk factors. Pooled effects were calculated by inverse-variance random-effects meta-analysis. Potential sources of heterogeneity and study biases were evaluated.

Findings

From 10 169 abstracts reviewed, 121 studies (82 [68%] randomised controlled trials and 39 [32%] quasi-experimental interventions) met the eligibility criteria. Most studies were done in North America (57 [47%]), and Europe, Australia, or New Zealand (36 [30%]). The median number of participants was 413·0 (IQR 124·0–904·0), and median duration of intervention was 9·0 months (4·5–18·0). Workplace wellness programmes improved fruit and vegetable consumption (0·27 servings per day [95% CI 0·16 to 0·37]), fruit consumption (0·20 servings per day [0·11 to 0·28]), body-mass index (−0·22 kg/m² [−0·28 to −0·17]), waist circumference (−1·47 cm [−1·96 to −0·98]), systolic blood pressure (−2·03 mm Hg [−3·16 to −0·89]), and LDL cholesterol (−5·18 mg/dL [−7·83 to −2·53]), and to a lesser extent improved total fat intake (−1·18% of daily energy intake [−1·78 to −0·58]), saturated fat intake (−0·70% of daily energy [−1·22 to −0·18]), bodyweight (−0·92 kg [−1·11 to −0·72]), diastolic blood pressure (−1·11 mm Hg [−1·78 to −0·44]), fasting blood glucose (−1·81 mg/dL [−3·33 to −0·28]), HDL cholesterol (1·11 mg/dL [0·48 to 1·74]), and triglycerides (−5·38 mg/dL [−9·18 to −1·59]). No significant benefits were observed for intake of vegetables (0·03 servings per day [95% CI −0·04 to 0·10]), fibre (0·26 g per day [−0·15 to 0·67]), polyunsaturated fat (−0·23% of daily energy [−0·59 to 0·13]), or for body fat (−0·80% [−1·80 to 0·21]), waist-to-hip ratio (−0·00 ratio [−0·01 to 0·00]), or lean mass (1·01 kg [−0·82 to 2·83]). Heterogeneity values ranged from 46·9% to 91·5%. Between-study differences in outcomes were not significantly explained by study design, location, population, or similar factors in heterogeneity analyses.

Interpretation

Workplace wellness programmes are associated with improvements in specific dietary, anthropometric, and cardiometabolic risk indicators. The heterogeneity identified in study designs and results should be considered when using these programmes as strategies to improve cardiometabolic health.

Effectiveness of Workplace Interventions to Reduce the Risk for Type 2 Diabetes: A Systematic Review and Meta-Analysis

OBJECTIVES

Workplace type 2 diabetes (T2D) prevention programs vary in intervention, delivery and methodologic approaches. Using predetermined criteria, we evaluated the effect and implementation of workplace interventions to prevent T2D.

METHODS

We searched Embase, MEDLINE and Cochrane Central Register of Controlled Trials databases from January 2000 to June 2020 to overlap with the launch of the Diabetes Prevention Program (DPP) in 2002. Two reviewers independently screened and extracted data from eligible controlled trials.

RESULTS

Five trials met the inclusion criteria, which included 1,494 adult participants; 791 (53%) were randomized to workplace interventions and 703 to usual workplace approaches. Pooled analysis showed that, when compared with controls, the participants in DPP-based interventions were 3.85 more likely to show a weight loss of ≥5% (4 randomized controlled trials [RCTs]; risk ratio [RR]=3.85; 95% confidence interval [CI], 1.58 to 9.38; p<0.05), and 9.36-fold more likely to show a weight loss of 7% (2 RCTs; RR=9.36; 95% CI, 2.31 to 37.97; p<0.05). The pooled evidence showed significant difference in effect favouring DPP-based interventions as compared with controls (4 RCTs; standardized mean difference, 0.38; 95% CI, 0.21 to 0.55; p<0.05). All included studies did have 3 common elements of the DPP: coaches, a focus on 7% weight loss and an increase in physical activity to a minimum of 150 min/week.

CONCLUSIONS

DPP interventions in the workplace continue to be an important and worthwhile strategy. Our review shows that such programs reveal promising evidence for weight loss and improved physical activities with less intensive and structured supports.

Translating CDSMP to the Workplace: Results of the Live Healthy Work Healthy Program

PURPOSE

Report the results of a randomized, controlled trial of Live Healthy, Work Healthy (LHWH), a worksite translation of the Chronic Disease Self-Management Program (CDSMP).

DESIGN

14 worksites were randomly assigned to LHWH, standard CDSMP (usual care) or no-intervention (control) group.

SETTING

The diverse set of work organizations centered around a rural community in SE US.

SUBJECTS

411 participants completed baseline data with 359 being included in the final analyses.

INTERVENTION

LHWH had been adapted to fit the unique characteristics of work organizations. This translated program consists of 15 sessions over 8 weeks and was facilitated by trained lay leaders.

MEASURES

The primary outcomes including health risk, patient-provider communication, quality of life, medical adherence and work performance were collected pretest, posttest (6 mos.) and follow-up (12 mos.).

ANALYSIS

Analyses were conducted using latent change score models in a structural equation modeling framework.

RESULTS

79% of participants reported at least one chronic condition with an average of 2.7 chronic conditions reported. Results indicated that LHWH program demonstrated positive changes in a most outcomes including significant exercise (uΔ = 0.89, p < .01), chronic disease self-efficacy (uΔ = 0.63, p < .05), fatigue (uΔ = -1.45, p < .05), stress (uΔ = -0.98, p < .01) and mentally unhealthy days (uΔ = -3.47, p < .001).

CONCLUSIONS

The translation of LHWH is an effective, low cost, embeddable program that has the potential to improve the health and work life of employees.

An Evaluation of the Reach and Effectiveness of a Diabetes Prevention Behaviour Change Program Situated in a Community Site

More than 350 million people are living with prediabetes. Preventing type 2 diabetes (T2D) progression can reduce morbidity, mortality and health-care costs. Interventions can support people with diet and physical activity behaviour changes; however, many interventions are university-based, posing barriers (e.g. accessibility, limited reach and maintenance), which highlight the need for community intervention. Limited research has comprehensively evaluated programs in community contexts. The purpose of this study was to pragmatically examine the reach and effectiveness of a diabetes prevention behaviour change program in the community using the RE-AIM framework. Demographic and outcome data were collected through telephone screening and survey data, and analyzed using descriptive and multivariate analyses. Over 2 years, 9,954 individuals were identified by a medical laboratory as living with prediabetes. Information letters were sent by the laboratory to individuals upon physician approval (N=2,241, 22.5%) as a main form of recruitment. From this, 271 individuals and an additional 160 individuals via other recruitment methods contacted the research team (N=431). Two hundred thirteen adults with prediabetes were enrolled (87.4% Caucasian, 69.7% female; 95% program completion). Analyses of 6-month follow-up data revealed significant maintenance of reductions in weight and waist circumference and improvements in physical function, self-reported physical activity and all-food frequency items except fruit intake (N=121, d=0.21 to 0.68, p <0.05 to 0.001). The program demonstrated diabetes risk-reducing benefits for enrolled individuals. Future work is needed to increase physician referral and participant response rates and to explore program expansion through digitization to reach more individuals at risk of developing T2D.

Health Promotion Programs and Policies in the Workplace: An Exploratory Study With Alaska Businesses

Introduction

We examined health insurance benefits, workplace policies, and health promotion programs in small to midsize businesses in Alaska whose workforces were at least 20% Alaska Native. Participating businesses were enrolled in a randomized trial to improve health promotion efforts.

Methods

Twenty-six Alaska businesses completed from January 2009 through October 2010 a 30-item survey on health benefits, policies, and programs in the workplace. We generated frequency statistics to describe overall insurance coverage, and to detail insurance coverage, company policies, and workplace programs in 3 domains: tobacco use, physical activity and nutrition, and disease screening and management.

Results

Businesses varied in the number of employees (mean, 250; median, 121; range, 41–1,200). Most businesses offered at least partial health insurance for full-time employees and their dependents. Businesses completely banned tobacco in the workplace, and insurance coverage for tobacco cessation was limited. Eighteen had onsite food vendors, yet fewer than 6 businesses offered healthy food options, and even fewer offered them at competitive prices. Cancer screening and treatment were the health benefits most commonly covered by insurance.

Conclusion

Although insurance coverage and workplace policies for chronic disease screening and management were widely available, significant opportunities remain for Alaska businesses to collaborate with federal, state, and community organizations on health promotion efforts to reduce the risk of chronic illness among their employees.

The workplace health group: A case study of 20 years of multidisciplinary research

The Workplace Health Group (WHG) was established in 1998 to conduct research on worker health and safety and organizational effectiveness. This multidisciplinary team includes researchers with backgrounds in psychology, health promotion and behavior, and intervention design, implementation, and evaluation. The article begins with a brief history of the team, its guiding principles, and stages of team formation and development. This section provides examples of the roles, team composition, structure, processes, cognition, leadership, and climate played in the various stages of team development, as well as how they influenced team effectiveness. The WHG formed with functional diversity-variety in knowledge, skills, and abilities-in mind, and the impact of this diversity is discussed throughout the article. Illustrations of how the functional diversity of the WHG has led to real-world impact are provided. The article concludes with some lessons learned and recommendations for creating and sustaining multidisciplinary teams based on the WHG's 20 years of experience and the team science literature.

The Effect of a Lifestyle Intervention on Weight Loss for University Employees

Obesity is a major health issue. A community-based intervention was implemented on a college campus to help employees lose body weight and fat. Participants were scanned using the InBody device at pre- and post-intervention, measuring body weight, fat, and waist circumference. Participants attended 11 classes on healthy lifestyle education. A comparison of pre- and post-intervention measurements was made using a paired t-test, resulting in a statistically significant difference in outcome measures. Correlation between class attendance and pounds lost showed a moderate negative correlation. Findings support a community-based lifestyle behavior intervention for weight and fat loss for university employees.

Patient Centered Studies Focusing on Diabetes Self-Management: A Scoping Review

BACKGROUND

Type 2 diabetes continues to be a significant burden to patients and health systems globally. Addressing this condition from an alternative perspective, patients and various other stakeholders from three northern Mississippi communities co-created patient-centered research questions focused on type 2 diabetes management.

OBJECTIVE

The objective of this scoping review was to explore current literature focusing on nine patient- centered research questions to establish current knowledge and identify future research needs in the area of type 2 diabetes.

METHODS

A scoping review was conducted to obtain an overview of research related to the study purpose. The PubMed database was searched from March 2013 to March 2018 to identify patient-centered studies focused on type 2 diabetes and relevant to one of the nine research questions.

RESULTS

A total of 33 studies were identified and included. For five of the research questions, there was either no previous research literature or only "related" studies could be identified. These largely unexplored topics included how the understanding of guidelines by healthcare providers, specialty, and communication of medication side-effects impact patients' understanding and outcomes, the impact of improving patients' preparedness to communicate with providers, and whether younger patients require weight management programs that account for this populations' needs.

CONCLUSION

This lack of previous literature presents a unique opportunity to partner with patients to conduct this study and help improve the management of type 2 diabetes.

Effect of workplace physical activity interventions on the cardio-metabolic health of working adults: systematic review and meta-analysis

Background

Adults in urban areas spend almost 77% of their waking time being inactive at workplaces, which leaves little time for physical activity. The aim of this systematic review and meta-analysis was to synthesize evidence for the effect of workplace physical activity interventions on the cardio-metabolic health markers (body weight, waist circumference, body mass index (BMI), blood pressure, lipids and blood glucose) among working adults.

Methods

All experimental studies up to March 2018, reporting cardio-metabolic worksite intervention outcomes among adult employees were identified from PUBMED, EMBASE, COCHRANE CENTRAL, CINAHL and PsycINFO. The Cochrane Risk of Bias tool was used to assess bias in studies. All studies were assessed qualitatively and meta-analysis was done where possible. Forest plots were generated for pooled estimates of each study outcome.

Results

A total of 33 studies met the eligibility criteria and 24 were included in the meta-analysis. Multi-component workplace interventions significantly reduced body weight (16 studies; mean diff: − 2.61 kg, 95% CI: − 3.89 to − 1.33) BMI (19 studies, mean diff: − 0.42 kg/m², 95% CI: − 0.69 to − 0.15) and waist circumference (13 studies; mean diff: − 1.92 cm, 95% CI: − 3.25 to − 0.60). Reduction in blood pressure, lipids and blood glucose was not statistically significant.

Conclusions

Workplace interventions significantly reduced body weight, BMI and waist circumference. Non-significant results for biochemical markers could be due to them being secondary outcomes in most studies. Intervention acceptability and adherence, follow-up duration and exploring non-RCT designs are factors that need attention in future research.

Reach, Uptake, and Satisfaction of Three Delivery Modes of FUEL Your Life

Background. FUEL Your Life (FYL) is a worksite translation of the Diabetes Prevention Program (DPP). In a randomized controlled trial, participants in a phone coaching condition demonstrated greater weight loss compared to participants in a group coaching or self-study condition. The purpose of this article is to describe the differences in participant reach, intervention uptake, and participant satisfaction for each delivery mode. Method. Employees who were overweight, obese, or at high risk for diabetes were recruited from city-county governments. Process evaluation data were collected from health coach records, participant surveys, and research team records. Differences between groups were tested using Pearson chi-square test and one-way analysis of variance. Results. Employee reach of targeted enrollment was highest for the self-study condition. Overall, intervention uptake was highest in the phone coaching condition. Participants who received phone coaching had increased uptake of the participant manual and self-monitoring of food compared to participants who received group coaching or self-study. Discussion. FYL demonstrated that DPP could be effectively delivered in the worksite by three different modalities. When implemented in a self-study mode, reach is greater but intervention uptake is lower. Phone health coaching was associated with greater intervention exposure.

Impact of a workplace holiday weight gain prevention program

BACKGROUND

The average worker gains 2-3 lb (0.9-1.4 kg) a year, about half of which is gained during the fall holiday season (Halloween through New Year's).

AIM

The aim of the study was to conduct a pilot test of a weight gain prevention program that was implemented in a workplace setting during the fall holiday season.

METHODS

239 state government employees participated in a weight gain prevention program offered during the fall holiday season. The program was a 10-week, team-based program that consisted of self-monitoring, regular weigh-ins, a team challenge, and organizational support. Weight was measured at baseline, every two weeks during the program, and post-program.

RESULTS

Participants lost a significant amount of weight (from 196.7 lb/89.2 kg to 192.3 lb/87.2 kg) during the program. Positive changes were observed in physical activity and eating behaviors.

CONCLUSIONS

This study demonstrated that a weight gain prevention program during a high risk period (fall holiday season) can be effective.

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.

Cost Effectiveness of a Weight Management Program Implemented in the Worksite: Translation of Fuel Your Life

OBJECTIVE

Conduct a cost-effectiveness analysis of the Fuel Your Life (FYL) program dissemination.

METHODS

Employees were recruited from three workplaces randomly assigned to one of the conditions: telephone coaching, small group coaching, and self-study. Costs were collected prospectively during the efficacy trial. The main outcome measures of interest were weight loss and quality-adjusted life years (QALYs).

RESULTS

The phone condition was most costly ($601 to $589/employee) and the self-study condition was least costly ($145 to $143/employee). For weight loss, delivering FYL through the small group condition was no more effective, yet more expensive, than the self-study delivery. For QALYs, the group delivery of FYL was in an acceptable cost-effectiveness range ($22,400/QALY) relative to self-study (95% confidence interval [CI]: $10,600/QALY-dominated).

CONCLUSIONS

Prevention programs require adaptation at the local level and significantly affect the cost, effectiveness, and cost-effectiveness of the program.

Impact of a Translated Disease Self-Management Program on Employee Health and Productivity: Six-Month Findings from a Randomized Controlled Trial

Disease management is gaining importance in workplace health promotion given the aging workforce and rising chronic disease prevalence. The Chronic Disease Self-Management Program (CDSMP) is an effective intervention widely offered in diverse community settings; however, adoption remains low in workplace settings. As part of a larger NIH-funded randomized controlled trial, this study examines the effectiveness of a worksite-tailored version of CDSMP (wCDSMP [n = 72]) relative to CDSMP (‘Usual Care’ [n = 109]) to improve health and work performance among employees with one or more chronic conditions. Multiple-group latent-difference score models with sandwich estimators were fitted to identify changes from baseline to 6-month follow-up. Overall, participants were primarily female (87%), non-Hispanic white (62%), and obese (73%). On average, participants were age 48 (range: 23–72) and self-reported 3.25 chronic conditions (range: 1–16). The most commonly reported conditions were high cholesterol (45%), high blood pressure (45%), anxiety/emotional/mental health condition (26%), and diabetes (25%). Among wCDSMP participants, significant improvements were observed for physically unhealthy days (uΔ = −2.07, p = 0.018), fatigue (uΔ = −2.88, p = 0.002), sedentary behavior (uΔ = −4.49, p = 0.018), soda/sugar beverage consumption (uΔ = −0.78, p = 0.028), and fast food intake (uΔ = −0.76, p = 0.009) from baseline to follow-up. Significant improvements in patient–provider communication (uΔ = 0.46, p = 0.031) and mental work limitations (uΔ = −8.89, p = 0.010) were also observed from baseline to follow-up. Relative to Usual Care, wCDSMP participants reported significantly larger improvements in fatigue, physical activity, soda/sugar beverage consumption, and mental work limitations (p < 0.05). The translation of Usual Care (content and format) has potential to improve health among employees with chronic conditions and increase uptake in workplace settings.

Effect of Intensity and Program Delivery on the Translation of Diabetes Prevention Program to Worksites: A Randomized Controlled Trial of Fuel Your Life

OBJECTIVE

The aim of this study was to evaluate the effectiveness of the Fuel Your Life program, an adaptation of the Diabetes Prevention Program (DPP), utilizing implementation strategies commonly used in worksite programs-telephone coaching, small group coaching, and self-study.

METHODS

The primary outcomes of body mass index and weight were examined in a randomized control trial conducted with city/county employees.

RESULTS

Although the majority of participants in all three groups lost some weight, the phone group lost significantly more weight (4.9 lb), followed by the small groups (3.4 lb) and the self-study (2.7 lb). Of the total participants, 28.3% of the phone group, 20.6% of the small group, and 15.7% of the self-study group lost 5% or more of their body weight.

CONCLUSIONS

Fuel Your Life (DPP) can be effectively disseminated using different implementation strategies that are tailored to the workplace.

Roles, responsibilities and characteristics of lay community health workers involved in diabetes prevention programmes: A systematic review

AIM

To examine the characteristics of community health workers (CHWs) involved in diabetes prevention programmes (DPPs) and their contributions to expected outcomes.

METHODS

Electronic databases including PubMed-MEDLINE, EBSCOHost, and SCOPUS/EMBASE were searched for studies published between January 2000 and March 2016. All studies that used CHWs to implement DPP in ≥18-year-old participants without diabetes but at high risk for developing the condition, irrespective of the study design, setting or outcomes measured, were included. Results were synthesized narratively.

RESULTS

Forty papers of 30 studies were identified. Studies were mainly community-based and conducted in minority populations in USA. Sample sizes ranged from 20 participants in a single community to 2369 participants in 46 communities. Although CHWs were generally from the local community, their qualifications, work experience and training received differed across studies. Overall the training was culturally sensitive and/or appropriate, covering topics such as the importance of good nutrition and the benefits of increased physical activity, communication and leadership. CHWs delivered a variety of interventions and also screened or recruited participants. The shared culture and language between CHWs and participants likely contributed to better programme implementation and successful outcomes.

CONCLUSIONS

The complexity of DPPs and the diverse CHW roles preclude attributing specific outcomes to CHW involvement. Nevertheless, documenting potential CHW roles and the relevant training required may optimise CHW contributions and facilitate their involvement in DPPs in the future.

Diabetes prevention in the real world: Insights from the JDPP and J-DOIT1

Type 2 diabetes (T2D) is associated with increased risks of morbidity and mortality. Diabetes prevention is an urgent issue in Japan. The Finnish Diabetes Prevention Study and US Diabetes Prevention Program revealed that intensive lifestyle intervention can prevent or delay the development of T2D in high-risk populations. Translational research varies in hospitals, primary care, communities, the workplace, and other settings. Translational research is feasible but less effective. There have been no long-term follow-ups. The outcome of the studies was mainly weight changes. The Japan Diabetes Prevention Program (JDPP) is a trial to test the efficacy of a lifestyle intervention program, which carried out in a primary healthcare setting using existing resources. The Japan Diabetes Outcome Trial-1 (J-DOIT1) is a nationwide telephone-delivered lifestyle intervention in a real-world setting. This review will focus on the effectiveness of a diabetes prevention program (recruitment, target population, method of intervention, and evaluation) in the real world and insights from the JDPP and J-DOIT1.

Evaluation of a Digital Behavioral Counseling Program for Reducing Risk Factors for Chronic Disease in a Workforce

OBJECTIVE

To evaluate a digitally delivered, intensive behavioral counseling program for a workforce at risk for obesity-related chronic disease.

METHODS

Employees were offered a digital health program modeled after the diabetes prevention program (DPP). Annual workforce health assessments were used to examine changes in chronic disease risk factors between participants (n = 634) relative to a matched comparison group (n = 1268).

RESULTS

Overall, employees were gaining an average of 3.5 pounds annually before program inception. Program engagement was positive; 83% completed the majority of the curriculum and 31% lost at least 5% of their starting weight. Compared with non-participating peers, participants demonstrated reduced weight, improved fasting blood glucose, and improved nutritional intake after a year.

CONCLUSIONS

The digital health program was effective for engaging employees in health behavior change. Digital options facilitate widespread implementation.

Randomized Trials of Nurse-Delivered Interventions in Weight Management Research: A Systematic Review

The purpose of this systematic review was to determine whether nurse-delivered weight management interventions improve weight outcomes across the life span. We conducted a comprehensive search of the PubMed, CINAHL, and PsycINFO electronic databases. We graded the trials using an adapted Jadad approach for methodological quality. The search identified a total of 1,159 citations; 23 articles from 20 studies were eligible for this review. Sixty-five percent of the studies reported significant findings related to body mass index (BMI) or weight reduction. Studies that were particularly successful at helping participants reduce weight and/or BMI involved nurses engaged in health promotion activities, operating within multidisciplinary teams and/or providing consultations, physical activity education, and coaching over the phone. Of the studies that involved long-term follow-up assessments, three out of nine studies showed a significant loss in weight or BMI between the intervention and control groups at follow-up times ranging from 12 months to 2 years.

A Critical Examination of the Use of Trained Health Coaches to Decrease the Metabolic Syndrome for Participants of a Community-Based Diabetes Prevention and Management Program

The epidemic of obesity and diabetes in the United States poses major challenge to the prevention and management of chronic diseases. Furthermore, when this is viewed in other components of the metabolic syndrome (i.e., the burden of high cholesterol and hypertension), the prevalence of the metabolic syndrome continues to rise in the USA continued challenge is how to deal with this epidemic from a medical and public health standpoint. Community Based Participatory Research (CBPR) is a unique approach and offers a novel perspective for answering this challenge. A critical set of goals for CBPR is to address health disparities and social inequalities while getting community members engaged in all aspects of the research process. Utilizing the West Virginia Diabetes Prevention and Management Program and trained Health Coaches as a model, we discuss topics of consideration related to CBPR, involving trained health coaches, optimizing early adoption of healthy lifestyle behaviors, and enhancing participation. Through careful project planning and design, questions regarding disparities increasing susceptibility and preventive efforts within the community can be addressed successfully. These topics are part of a broader integration of theories such as participatory research, community engagement, and outcomes measurement. The understanding of the pathophysiology and epidemiology of the metabolic syndrome can help frame an appropriate strategy for establishing long-term community-wide changes that promote health. In order to continue to improve investigations for preventing the metabolic syndrome, it will be necessary to have aggressive efforts at the individual and population level for developing culturally sensitive programs that start early and are sustainable in practical environments such as the workplace. In this comprehensive review, we will discuss practical considerations related to project design, implementation, and how to measure effectiveness in regards to reducing the burden of the metabolic syndrome.

A Randomized Controlled Trial Translating the Diabetes Prevention Program to a University Worksite, Ohio, 2012-2014

Introduction

Working adults spend much time at the workplace, an ideal setting for wellness programs targeting weight loss and disease prevention. Few randomized trials have evaluated the efficacy of worksite diabetes prevention programs. This study evaluated the efficacy of a worksite lifestyle intervention on metabolic and behavioral risk factors compared with usual care.

Methods

A pretest–posttest control group design with 3-month follow-up was used. Participants with prediabetes were recruited from a university worksite and randomized to receive a 16-week lifestyle intervention (n = 35) or usual care (n = 34). Participants were evaluated at baseline, postintervention, and 3-month follow-up. Dietary intake was measured by a food frequency questionnaire and level of physical activity by accelerometers. Repeated measures analysis of variance compared the change in outcomes between and within groups.

Results

Mean (standard error [SE]) weight loss was greater in the intervention (−5.5% [0.6%]) than in the control (−0.4% [0.5%]) group (P < .001) postintervention and was sustained at 3-month follow-up (P < .001). Mean (SE) reductions in fasting glucose were greater in the intervention (−8.6 [1.6] mg/dL) than in the control (−3.7 [1.6] mg/dL) group (P = .02) postintervention; both groups had significant glucose reductions at 3-month follow-up (P < .001). In the intervention group, the intake of total energy and the percentage of energy from all fats, saturated fats, and trans fats decreased, and the intake of dietary fiber increased (all P < .01) postintervention.

Conclusion

The worksite intervention improved metabolic and behavioral risk factors among employees with prediabetes. The long-term impact on diabetes prevention and program sustainability warrant further investigation.

Healthy Team Healthy U: A Prospective Validation of an Evidence-Based Worksite Health Promotion and Wellness Platform

Objective

To evaluate the effects of a research-tested, team-based health promotion and wellness program combined with digital technologies and implemented in a diverse worksite setting among hospital, clinic, and university employees.

Methods

A prospective cohort study of employees completing biometrics and questionnaires before and after the initial 12-session wellness program and its 12-session booster, 1 year later.

Results

After both the initial intervention and booster, blood pressure and weight were reduced, with greater reductions among employees with pre-hypertension and hypertension and those with a body mass index ≥25. After both the initial intervention and booster, there was a significant increase in (1) daily intake of fruit and vegetable servings, (2) days/week of ≥30 min of exercise, (3) days/week of strength training, and (4) levels of moderately vigorous and vigorous daily physical activity. Self-reported indices of both depression and work-related stress were reduced, while participants reported increased happiness. Post booster, average sleep quality, and sleep duration increased among higher risk employees reporting ≤6 h of daily sleep. Employees reported receiving encouragement from co-workers to engage in healthful diet and physical activities, and exercised together more, and indicated that they would recommend the program to other employees. Longitudinal analysis revealed the durability of the initial intervention outcomes with further beneficial effects after the booster.

Conclusion

A research tested, comprehensive team-based health promotion and wellness program, combined with digital technologies, improved employee health behaviors, mood, sleep, elements of co-worker cohesion, and biometrics among a diverse multi-site workforce. Positive program effects were durable, with enhanced results after the booster.
