Effect of a Workplace Weight-Loss Program for Overweight and Obese Healthcare Workers

Addressing Health Care Workers' Mental Health: A Systematic Review of Evidence-Based Interventions and Current Resources

Background. Mental health is declining in health care workers. Objectives. To provide a comprehensive assessment of intervention literature focused on the support and treatment of mental health within the health care workforce. Search Methods. We searched online databases (e.g., Medline, PsycINFO). Selection Criteria. We selected manuscripts published before March 2022 that evaluated the target population (e.g., nurses), mental health outcomes (e.g., burnout, depression), and intervention category (e.g., mindfulness). Data Collection and Analysis. Of 5158 publications screened, 118 interventions were included. We extracted relevant statistics and information. Main Results. Twenty (17%) earned study quality ratings indicating design, analysis, and implementation strengths. Randomized controlled trials were used by 52 studies (44%). Thirty-eight percent were conducted in the United States (n = 45). Ninety (76%) reported significant changes, and 46 (39%) reported measurable effect sizes. Multiple interventions significantly reduced stress (n = 29; 24%), anxiety (n = 20; 17%), emotional exhaustion or compassion fatigue (n = 16; 14%), burnout (n = 15; 13%), and depression (n = 15; 13%). Authors' Conclusions. Targeted, well-designed mental health interventions can improve outcomes among health care workers. Public Health Implications. Targeted health care‒focused interventions to address workers' mental health could improve outcomes within this important and vulnerable workforce.

Impact of COVID-19 on a worksite weight loss program for employees with overweight and obesity

Objective

The COVID-19 pandemic has been shown to be negatively associated with physical activity engagement, adherence to healthy diet, and weight management among people with obesity. The current study examined COVID-19-related changes in weight, physical activity (PA), and diet among employees with obesity or overweight who participated in Vibrant Lives (VL), a worksite weight loss program.

Methods

School district employees participated in the 6-month VL weight loss program and were categorized into non-COVID-era participants and COVID-era participants. Participants completed questionnaires about PA and dietary intake at baseline and follow-up. COVID-era participants reported the effects of pandemic on their behaviors. Changes in weight, PA, and diet were compared between groups using multilevel linear mixed models and logistic regression models.

Results

A total of 266 participants (non-COVID, n=173; COVID, n=93) were included. Significant weight loss (non-COVID, -2.3 kg vs. COVID, -1.3 kg) and increases in moderate-to-vigorous PA minutes (non-COVID, 48.7 min vs. COVID, 61.5 min) were observed associated with the program, but no significant differences in changes between the groups were found. Compared to non-COVID participants, COVID participants decreased fast food consumption (P=.008) and increased sugar-sweetened beverage intake (P=.016). Higher frequency of snacking and overeating were reported as barriers to a healthy diet.

Conclusion

The COVID-19 pandemic was negatively associated with healthful dietary behaviors. The information obtained from participants regarding the reasons for their pandemic-related changes in diet may help identify strategies to encourage healthier behaviors and weight management among people who have been negatively affected by the COVID-19 pandemic.This article is protected by copyright.

The active ingredients of physical activity and / or dietary workplace-based interventions to achieve weight loss in overweight and obese healthcare staff: a systematic review

This systematic review aims to synthesize the active ingredients, and identify a list of promising behaviour change techniques (BCTs), likely to be present within physical activity and / or dietary interventions in achieving weight loss in overweight and obese healthcare staff. Four electronic databases were searched in February 2021: PsychINFO, CINAHL, PubMed and MEDLINE (no start date-2021). Studies were eligible for inclusion if they: (1) described a quasi-experimental or cluster, cohort or randomised control trial; (2) implemented workplace-based physical activity and / or dietary interventions versus a less intensive intervention or usual care; (3) targeted predominantly (> 50% of participants) overweight or obese healthcare professionals; and (4) reported a weight loss related outcome and included data on that outcome at least 3 months after the intervention began. Three reviewers used the Behaviour Change Technique Taxonomy v1 to extract BCTs with the aim of identifying a list of "promising" BCTs, which were those that were present in interventions that reported a statistically significant difference in weight loss. Nine studies were included in the review. The majority (n = 7) reported a significant reduction in weight post-intervention. A combined physical activity and dietary intervention (n = 8) was the most common type of intervention. Twenty-five BCTs were identified as "promising". Instruction on how to perform the behaviour (n = 9), behaviour practice/rehearsal (n = 8) and self-monitoring of behaviour (n = 6) were the most promising BCTs. The contents of behaviour change interventions are complex and rely on accurate reporting of intervention components and BCTs to allow concrete and robust assumptions to be made regarding which factors are most effective at achieving a desired outcome. Fundamentally the lack of research exploring the effectiveness of physical activity and dietary interventions on weight loss in overweight and obese healthcare staff and the poor quality of existing research, warrant more investigation.

Weight Reduction Interventions Using Digital Health for Employees with Obesity: A Systematic Review

PURPOSE

This study aimed to systematically review the literature on randomized controlled trials on weight reduction interventions using digital health for employees with obesity.

METHODS

All relevant articles published until September 2021 were systematically identified from six electronic databases: MEDLINE, EMBASE, CINAHL, PsycINFO, RISS, and KISS. Data selection and extraction were independently performed by three researchers. Methodological quality was assessed using the JBI Critical Appraisal Checklist for Randomized Controlled Trials. The results were narratively synthesized.

RESULTS

Eleven studies were included in the systematic review. All studies had a low risk of bias. The settings and sample sizes of the included studies were different. The contents of the interventions included nutrition, physical activity, behavioral change, incentives, and motivation. Four studies were based on social cognitive theory. A total of ten studies delivered web-based intervention, while the other used tele-monitoring device. A wide range of intervention strategies was used including providing online resources, tele-counseling, and patient-tailored advice. As a result of the intervention, a total of seven studies showed a significant weight reduction in both the intervention and comparison groups, with significant differences between groups.

CONCLUSION

Until now, use of digital health in weight reduction interventions for employees with obesity has been conducted on a web-based. Various contents such as nutrition, physical activity and theories were explored. Further study is required using more diverse delivery methods such as mobile application, use of wearable devices.
