Lifestyle Medicine: Prevention, Treatment, and Reversal of Disease.

Lifestyle medicine (LM) expands the scope of preventive medicine by focusing on the promotion of healthy lifestyles while preventing, treating, and reversing the vast majority of chronic diseases caused by behaviors and environmental factors. LM focuses on six pillars-a plant-predominant eating pattern; physical movement; restorative sleep; management of stress; avoidance of risky substances; and positive social connections. Advances in LM competencies, education, certification, resources, and practice models are accelerating with a particular need and focus on underserved and most seriously impacted patients and communities. A comprehensive and integrated strategy addressing "whole person health" is emerging as a compelling framework for providers and health systems which combines a foundational commitment to prevention with a systematic approach to the actual and root causes of premature disease, disability, and death.

Prioritized Research for the Prevention, Treatment, and Reversal of Chronic Disease: Recommendations From the Lifestyle Medicine Research Summit.

Declining life expectancy and increasing all-cause mortality in the United States have been associated with unhealthy behaviors, socioecological factors, and preventable disease. A growing body of basic science, clinical research, and population health evidence points to the benefits of healthy behaviors, environments and policies to maintain health and prevent, treat, and reverse the root causes of common chronic diseases. Similarly, innovations in research methodologies, standards of evidence, emergence of unique study cohorts, and breakthroughs in data analytics and modeling create new possibilities for producing biomedical knowledge and clinical translation. To understand these advances and inform future directions research, The Lifestyle Medicine Research Summit was convened at the University of Pittsburgh on December 4-5, 2019. The Summit's goal was to review current status and define research priorities in the six core areas of lifestyle medicine: plant-predominant nutrition, physical activity, sleep, stress, addictive behaviors, and positive psychology/social connection. Forty invited subject matter experts (1) reviewed existing knowledge and gaps relating lifestyle behaviors to common chronic diseases, such as cardiovascular disease, diabetes, many cancers, inflammatory- and immune-related disorders and other conditions; and (2) discussed the potential for applying cutting-edge molecular, cellular, epigenetic and emerging science knowledge and computational methodologies, research designs, and study cohorts to accelerate clinical applications across all six domains of lifestyle medicine. Notably, federal health agencies, such as the Department of Defense and Veterans Administration have begun to adopt "whole-person health and performance" models that address these lifestyle and environmental root causes of chronic disease and associated morbidity, mortality, and cost. Recommendations strongly support leveraging emerging research methodologies, systems biology, and computational modeling in order to accelerate effective clinical and population solutions to improve health and reduce societal costs. New and alternative hierarchies of evidence are also be needed in order to assess the quality of evidence and develop evidence-based guidelines on lifestyle medicine. Children and underserved populations were identified as prioritized groups to study. The COVID-19 pandemic, which disproportionately impacts people with chronic diseases that are amenable to effective lifestyle medicine interventions, makes the Summit's findings and recommendations for future research particularly timely and relevant.

The Complete Health Improvement Program (CHIP) and reduction of chronic disease risk factors in Canada.

PURPOSE: The short-term effectiveness of the nutrition-centred Complete Health Improvement Program (CHIP) lifestyle intervention for improving selected chronic disease risk factors was examined in the Canadian setting. METHODS: A total of 1003 people (aged 56.3 ± 12.1 years, 68% female) were self-selected to participate in one of 27 CHIP interventions hosted in community settings by Seventh-day Adventist churches throughout Canada, between 2005 and 2011. The program centred on the promotion of a whole-food, plant-based eating pattern, and daily physical activity was also encouraged. Biometric measures, including body mass index (BMI), blood pressure (BP), blood lipid profile, and fasting blood sugar (FBS), were determined at program entry and 30 days into the intervention. RESULTS: Over 30 days, significant overall reductions (P<0.001) were recorded in the participants' BMI (-3.1%), systolic BP (-7.3%), diastolic BP (-4.3%), total cholesterol ([TC] -11.3%), low-density lipoprotein cholesterol ([LDL-C] -12.9%), triglycerides ([TG] -8.2%), and FBS (-7.0%). Participants with the highest classifications of TC, LDL-C, TG, and FBS at program entry experienced approximately 20% reductions in these measures in 30 days. CONCLUSIONS: The CHIP intervention, which centres on a whole-food, plant-based eating pattern, can lead to rapid and meaningful reductions in chronic disease risk factors in the Canadian context.

Residency education, preventive medicine, and population health care improvement: the Dartmouth-Hitchcock Leadership Preventive Medicine approach.

In 2003, Dartmouth-Hitchcock Medical Center (DHMC) inaugurated its Leadership Preventive Medicine residency (DHLPMR), which combines two years of leadership preventive medicine (LPM) training with another DHMC residency. The aim of DHLPMR is to attract and develop physicians who seek to become capable of leading change and improvement of the systems where people and health care meet. The capabilities learned by residents are (1) leadership -- including design and redesign -- of small systems in health care, (2) measurement of illness burden in individuals and populations, (3) measurement of the outcomes of health service interventions, (4) leadership of change for improvement of quality, value, and safety of health care of individuals and populations, and (5) reflection on personal professional practice enabling personal and professional development. The DHLPMR program includes completion of an MPH degree at The Dartmouth Institute for Health Policy and Clinical Practice (formerly the Center for Evaluative Clinical Sciences) and a practicum during which the resident leads change to improve health care for a defined population of patients. Residents also complete a longitudinal public health experience in a governmental public health agency. A coach in the resident's home clinical department helps the resident develop his or her practicum proposal, which must then be approved by a practicum review board (PRB). Twelve residents have graduated as of July 2007. Residents have combined anesthesia, family medicine, internal medicine, infectious disease, pain medicine, pathology, psychiatry, pulmonary and critical care medicine, surgery, gastroenterology, geriatric psychiatry, obstetrics-gynecology, and pediatrics with preventive medicine.
