Lifestyle Medicine Implementation in 8 Health Systems: Protocol for a Multiple Case Study Investigation.

BACKGROUND: Lifestyle medicine (LM) is the use of therapeutic lifestyle changes (including a whole-food, plant-predominant eating pattern; regular physical activity; restorative sleep; stress management; avoidance of risky substances; and positive social connection) to prevent and treat chronic illness. Despite growing evidence, LM is still not widely implemented in health care settings. Potential challenges to LM implementation include lack of clinician training, staffing concerns, and misalignment of LM services with fee-for-service reimbursement, but the full range of factors facilitating or obstructing its implementation and long-term success are not yet understood. To learn important lessons for success and failure, it is crucial to understand the experiences of different LM programs. OBJECTIVE: This study aims to describe in depth the protocol used to identify barriers and facilitators impacting the implementation of LM in health systems. METHODS: The study team comprises team members at the American College of Lifestyle Medicine (ACLM), including staff and researchers with expertise in public health, LM, and qualitative research. We recruited health systems that were members of the ACLM Health Systems Council. From among 15 self-nominating health systems, we selected 7 to represent a diversity of geographic location, type, size, expertise, funding, patients, and LM services. Partway through the study, we recruited 1 additional contrasting health system to serve as a negative case. For each case, we conducted in-depth interviews, document reviews, site visits (limited due to the COVID-19 pandemic), and study team debriefs. Interviews lasted 45-90 minutes and followed a semistructured interview guide, loosely based on the Consolidated Framework for Implementation Research (CFIR) model. We are constructing detailed case narrative reports for each health system that are subsequently used in cross-case analyses to develop a contextually rich and detailed understanding of various predetermined and emergent topics. Cross-case analyses will draw on a variety of methodologies, including in-depth case familiarization, inductive or deductive coding, and thematic analysis, to identify cross-cutting themes. RESULTS: The study team has completed data collection for all 8 participating health systems, including 68 interviews and 1 site visit. We are currently drafting descriptive case narratives, which will be disseminated to participating health systems for member checking and shared broadly as applied vignettes. We are also conducting cross-case analyses to identify critical facilitators and barriers, explore clinician training strategies to facilitate LM implementation, and develop an explanatory model connecting practitioner adoption of LM and experiences of burnout. CONCLUSIONS: This protocol paper offers real-world insights into research methods and practices to identify barriers and facilitators to the implementation of LM in health systems. Findings can advise LM implementation across various health system contexts. Methodological limitations and lessons learned can guide the execution of other studies with similar methodologies.

Formative evaluation of a portion control and calorie reduction campaign: Insights from focus groups with target audience.

Healthy eating campaigns can increase awareness of healthful foods and eating patterns and prompt behavior change. Portion control can be a useful strategy in weight management efforts, and new, innovative campaigns can help invigorate messages related to portion control and weight management. This qualitative study presents results of formative testing of portion control and calorie reduction messages and infographics for a proposed campaign. We conducted 17 focus groups with 113 adults ages 18-65 years in 3 US cities. We conducted separate focus groups by weight status (overweight/healthy weight) and gender (male/female) and analyzed coded data and categorized emerging themes. Participants, especially those with healthy weights, gravitated toward specific, and achievable messages to encourage portion control and calorie reduction. Men with overweight and women with healthy weights preferred messages that had a positive, supportive tone. Participants favored messages that addressed overeating and allowed for autonomy. In particular, women and those with healthy weights preferred messages that encouraged calorie budgeting. Many participants, in particular men, provided positive feedback on messages encouraging a "fresh start" on Mondays. Additionally, participants preferred messages that were colorful, informative, realistic, attractive, and relatable. With regard to message dissemination, participants suggested that messages and infographics be positioned in high-traffic areas and men generally suggested places where food decisions are made. Moreover, participants suggested message dissemination through trusted health professionals and credible research organizations. Health organizations planning a portion control or calorie reduction campaign should consider these factors early in the development process to help ensure acceptance and success.

A Public Health Messaging Campaign to Reduce Caloric Intake: Feedback From Expert Stakeholders.

OBJECTIVE: To obtain expert feedback on a public health messaging campaign to reduce caloric intake in US adults. DESIGN AND SETTING: In 2018, researchers conducted semistructured telephone interviews with US-based experts in obesity prevention, mental health, and health communications. PARTICIPANTS: The research team invited 100 experts to participate using purposive and snowball sampling techniques. Of those invited, 60 completed interviews, among which 37 (62%) were obesity prevention experts, 12 (20%) were mental health experts, and 11 (18%) were health communications experts. MAIN OUTCOME MEASURE: Expert feedback regarding a public health messaging campaign to reduce caloric intake. ANALYSIS: Two researchers reviewed and coded all transcripts. The team identified major themes and summarized findings. RESULTS: Most experts identified barriers to effective calorie reduction including social and environmental factors, lack of actionable strategies, and confusion regarding healthy eating messages. Expert suggestions for effective messaging included addressing eating patterns, emphasizing nutrient density, and dissemination through multiple channels and trusted sources. In general, mental health experts more frequently voiced concerns regarding eating disorders, and communications experts raised issues regarding the dissemination of campaigns. CONCLUSIONS AND IMPLICATIONS: Professionals should identify and address barriers to delivering a calorie reduction campaign before implementation, using strategies that enhance delivery to ensure an effective campaign.

Positive effect of mushrooms substituted for meat on body weight, body composition, and health parameters. A 1-year randomized clinical trial.

Reducing energy density (ED) of the diet is an important strategy for controlling obesity. This 1-year, randomized clinical trial examined the effect of substituting mushrooms for red meat ('mushroom diet'), compared to a standard diet ('meat diet'), on weight loss and maintenance among 73 obese adults (64 women, 9 men). The subjects completed anthropometric measurements and 7-day food records four times during a standardized weight loss and maintenance regimen. At the end of the 1-year trial, compared to participants on the standard diet, participants on the mushroom diet (n=36) reported lower intakes of energy (mean ± [SE]=-123 ± 113 kcals) and fat (-4.25 ± 6.88 g), lost more pounds and percentage body weight (-7.03 ± 3.34 lbs, 3.6%), achieved lower body mass index (-1.53 ± 0.36), waist circumference (-2.6 ± 3.5 in.) and percent total body fat (-0.85 ± 0.53), and had lower systolic and diastolic pressure (-7.9 and -2.5 mmHg); their lipid profile and inflammatory markers also improved. After initial weight loss, subjects following the mushroom diet maintained that loss well. Those who completed the full 12-month trial still weighed a mean of 7 lbs less than baseline. Thus, encouraging adults to substitute mushrooms for red meat was a useful strategy for enhancing weight loss, weight maintenance, and health parameters.
