Mitigating preventable chronic disease: Progress report of the Cleveland Clinic's Lifestyle 180 program

Association of Healthy Lifestyle and Incident Polypharmacy

BACKGROUND

Polypharmacy, commonly defined as taking ≥5 medications, is an undesirable state associated with lower quality of life. Strategies to prevent polypharmacy may be an important priority for patients. We sought to examine the association of healthy lifestyle, a modifiable risk factor, with incident polypharmacy.

METHODS

We performed a secondary analysis of the REasons for Geographic and Racial Differences in Stroke (REGARDS) cohort study, including 15,478 adults aged ≥45 years without polypharmacy at baseline. The primary exposure was healthy lifestyle at baseline as measured by the Healthy Behavior Score (HBS), a cumulative assessment of diet, exercise frequency, tobacco smoking, and sedentary time. HBS ranges from 0-8, whereby 0-2 indicates low HBS, 3-5 indicates moderate HBS, and 6-8 indicates high HBS. We used multinomial logistic regression to examine the association between HBS and incident polypharmacy, survival without polypharmacy, and death.

RESULTS

Higher HBS (i.e., healthier lifestyle) was inversely associated with incident polypharmacy after adjusting for sociodemographic and baseline health variables. Compared with participants with low HBS, those with moderate HBS had lower odds of incident polypharmacy (odds ratio [OR] 0.85; 95% confidence interval [CI], 0.73-0.98) and lower odds of dying (OR 0.74; 95% CI, 0.65-0.83). Participants with high HBS had even lower odds of both incident polypharmacy (OR 0.75; 95% CI, 0.64-0.88) and death (OR 0.62; 95% CI, 0.54-0.70). There was an interaction for age, where the association between HBS and incident polypharmacy was most pronounced for participants aged ≤65 years.

CONCLUSIONS

Healthier lifestyle was associated with lower risk for incident polypharmacy.

Total Force Kitchen: Exploring Active-Duty Service Member Performance Optimization Through Cooking

Introduction: Obesity, overweight, and suboptimal eating habits are threats to U.S. active-duty service member (SM) nutritional fitness. Offering programs that improve diet quality and nutritional status is of high interest to military leaders. Methods: Total force kitchen (TFK) was developed as a performance-focused multicomponent program centered around culinary skills with education and skill building in key areas of nutrition, physical activity, and mindfulness. This pilot study's objectives were to determine the feasibility and acceptability of the TFK program, to make recommendations for program modification, and to determine impact on behavior, self-efficacy, and health-related outcomes. Participants were single or geographically single active-duty SMs (n = 17) who attended the 12-week, 60-h innovative culinary education and performance optimization program at a local United Service Organization facility. A mixed-method approach assessed pre- and post-program metrics, including attrition rates and participant satisfaction. Results: The TFK program retention rate was 76.5%. All participants were "somewhat satisfied" or "very satisfied" with the overall TFK program. The highest satisfaction was with the cooking-related components. Improvements in other behavioral (d = 0.39, 95% confidence interval [CI]: -0.17 to 0.95), self-rated health (d = 0.58, 95% CI: -0.02 to 0.16), and anthropometric measures (e.g., body fat percentage: d = -0.01, 95% CI: -0.12 to 0.10) were smaller than improvements in cooking attitudes (d = 0.66, 95% CI: 0.17 to 1.13) and self-efficacy for techniques (d = 1.80, 95% CI: 0.96 to 2.62). Participants reported positive changes in lifestyle related to what they eat and how they prepare their meals. They also highly valued active learning and instructor knowledge and enthusiasm. Discussion: This multidisciplinary evidence-based program offers ample opportunities for SMs to gain knowledge, build skills, and engage in a supportive community to optimize their performance through cooking. A successful pilot has the potential to leverage resources for the TFK program expanding its reach and impact to the larger military population and nonmilitary communities.

Feasibility pilot study of a Japanese teaching kitchen program

Background

This pilot study examined the feasibility of a new lifestyle modification program involving a "Teaching Kitchen" in Japan. Our goal was to explore (1) feasibility of the program; (2) acceptability for class frequency (weekly vs. bi-weekly); and (3) changes in biometrics, dietary intakes, and lifestyle factors.

Methods

A total of 24 employees with obesity in a Japanese company were recruited. Participants were randomly divided into two groups (weekly or bi-weekly group), each attending the program consisting of four two-hour classes (lectures on nutrition, exercise, mindfulness, and culinary instructions). Participants were observed for changes in dietary intakes, biometrics, and health related quality of life over the subsequent 3 months. We tested the between-group differences in changes using linear mixed-effect models.

Results

The program completion rates were 83.3% in total (91.7% for weekly group and 75.0% for bi-weekly group). From baseline to post-intervention, significant decreases were observed in weight (p < 0.001), body mass index (p < 0.001), diastolic blood pressure (p = 0.03), body fat mass (p < 0.001), and dietary intakes in total fat (p = 0.03) and sodium (p = 0.008) among 17 participants who were available for measurements. Improvements in biometrics remained significant 1 month after the intervention (all p ≤ 0.03 in 14 participants). Participants' health related quality of life was significantly improved in bodily pain, general health, vitality, and mental component score (all p ≤ 0.047).

Conclusions

The new Japanese Teaching Kitchen program is feasible with high program completion rates in Japanese office workers with obesity. While this was a small feasibility study, significant multiple improvements in dietary intakes, biometrics, and health related quality of life suggest that this line of inquiry warrants further exploration to address obesity and obesity-related diseases in Japan.

Teaching Kitchens and Culinary Gardens as Integral Components of Healthcare Facilities Providing Whole Person Care: A Commentary

Child and adult obesity continue to be major health concerns in the United States and can contribute to the development of chronic diseases. Culinary medicine, which incorporates teaching kitchens and gardens, may be a useful strategy for preventing and/or treating obesity-related disease by providing the knowledge and skills that encourage consumption of whole plant-based foods prepared at home. Though emerging research describes the benefits of culinary medicine-based programming, examples of teaching kitchens and culinary gardens being integrated into current clinical practice is minimal. Here, we describe the development of innovative, community-centered culinary medicine programming borne from interdisciplinary collaboration at a leading healthcare system. Preliminary outcomes suggest improvements in anthropometrics, cardiometabolic risk factors, and participation in healthy lifestyle behaviors in pediatric weight management patients, as well as improved confidence, knowledge, and likelihood to prepare whole food, plant-based meals in healthcare employees following participation in culinary medicine workshops. Hospitals and culinary medicine partners can support each other through shared knowledge, vision, and resources to provide value-based care to patients in the community. Collaboration among gardeners, chefs, architects, educators, and healthcare professionals can transfer traditional physician-driven care to patients, empowering them with the tools, resources, and confidence to improve health and wellbeing.

Perspective: Teaching Kitchens: Conceptual Origins, Applications and Potential for Impact within Food Is Medicine Research

There is a need to identify innovative strategies whereby individuals, families, and communities can learn to access and prepare affordable and nutritious foods, in combination with evidence-based guidance about diet and lifestyle. These approaches also need to address issues of equity and sustainability. Teaching Kitchens (TKs) are being created as educational classrooms and translational research laboratories to advance such strategies. Moreover, TKs can be used as revenue-generating research sites in universities and hospitals performing sponsored research, and, potentially, as instruments of cost containment when placed in accountable care settings and self-insured companies. Thus, TKs can be considered for inclusion in future health professional training programs, and the recently published Biden-Harris Administration Strategy on Hunger, Nutrition and Health echoes this directive. Recent innovations in the ability to provide TK classes virtually suggest that their impact may be greater than originally envisioned. Although the impact of TK curricula on behaviors, outcomes and costs of health care is preliminary, it warrants the continued attention of medical and public health thought leaders involved with Food Is Medicine initiatives.

Culinary Medicine as Innovative Nutrition Education for Medical Students: A Scoping Review

PURPOSE

Lifestyle-related disease substantially impacts health, but physicians lack adequate nutrition education to discuss behavioral change with patients. Many medical schools have developed culinary medicine programs as a nutrition education strategy, but common elements of success have not been defined.

METHOD

The authors conducted a scoping review of the literature on culinary medicine programs for medical students. They searched PubMed, Ovid MEDLINE, and MedEdPORTAL databases to identify English-language studies published between January 1, 2012, and October 15, 2021. Multiple search terms were used to identify medical student-focused culinary medicine programs. The authors focused inclusion criteria on medical student learners, curricular description, hands-on cooking components, reflection or application to patient care, and assessment. Additionally, the authors reviewed 2 online databases which list programs delivering culinary medicine education for U.S. medical students.

RESULTS

Authors identified 251 studies, of which 12 met inclusion criteria. These studies described programs that used a kitchen or similar space adaptable for food preparation to enable hands-on learning, and some programs provided opportunities for practical application. Most programs administered surveys to assess course impact, but the type of survey and cohort size varied. Culinary medicine programs for medical students varied in learner level, number of participants, course length and structure, and instructor background but consistently improved student knowledge in key areas of nutrition application and changed knowledge and attitudes about food and nutrition. Funding was often noted as a barrier to program sustainability. When funding source was provided, it derived from philanthropic or academic sources. When the authors reviewed the 2 online databases, they identified 34 programs offering medical student-focused culinary medicine courses.

CONCLUSIONS

As culinary education programs emerge across academic centers, standardizing programmatic and curricular elements, best practices, and assessment strategies will be vital for quality control, sustainability, and optimal population health impact.

Promoting healthy lifestyle habits among participants in cancer screening programs: Results of the randomized controlled Sti.Vi study

Background:

Unhealthy diets, physical inactivity, alcohol and tobacco consumption are among the leading risk factors for non-communicable diseases. It is estimated that around 40% of cancers could be prevented by adopting healthy lifestyles.

Design and methods:

The Stili di Vita (Sti.Vi) study was a randomized study for assessing the impact of healthy lifestyle interventions on anthropometric measures, metabolic parameters, and health outcomes among participants of cancer screening programs in Turin (Italy). Eligible women aged 50–54 years, invited to biennial mammography screening, and 58-years-old men and women, invited to a once-only sigmoidoscopy for colorectal cancer (CRC) screening were randomly allocated to Diet group (DG), Physical Activity group (PAG), Physical Activity plus Diet group (PADG), or control group (CG). Physical and eating habits, metabolic and anthropometric measurements, repeatedly collected, were the study outcomes. The active intervention, offered to participants assigned to the DG, PAG, and PADG arms, consisted of a basic module and an advanced module. The effect of the interventions was estimated through logistic regression or a difference in differences approach. A multiple imputation procedure was implemented to deal with missing values and q-values have been calculated in the presence of multiple hypothesis testing.

Results:

Out of the 8442 screened attendees, 1270 signed informed consent, while 1125 participants accomplished the baseline visit. Participants were equally distributed across the four treatments as following: 273 (24.3%) in DG, 288 (25.6%) in the PAG, 283 (25.1%) in PADG, and 281 (25%) in the CG. Participants assigned to DG or PADG increased their consumption of whole grains (OR = 1.77, 95% CI: 1.20–2.60 and OR = 1.55, 95% CI: 1.06–2.27, respectively) and legumes (OR = 1.77, 95% CI: 1.12–2.79 and OR = 2.24, 95% CI: 1.41–3.57, respectively), with respect to CG. The participants randomized to DG reduced processed meat and increased fruit consumption (OR = 2.57, 95% CI: 1.76–3.76 and OR = 2.38, 95% CI: 1.12–5.06, respectively). The effects were more evident in the CRC screening subgroup. No relevant difference was observed between PAG and CG. No impact was observed on physical activity habits.

Conclusions:

Our findings suggest that active interventions can increase awareness and induce diet changes. However, participation rate and compliance to the courses was quite low, innovative strategies to enhance participants’ retention are needed, with the ultimate goal of increasing awareness and inducing positive lifestyle changes.

Development and Validation of a New Home Cooking Frequency Questionnaire: A Pilot Study

Home cooking and the type of cooking techniques can have an effect on our health. However, as far as we know, there is no questionnaire that measures in depth the frequency and type of cooking techniques used at home. Our aim was to design a new Home Cooking Frequency Questionnaire (HCFQ) and to preliminarily assess its psychometric properties. For this purpose we used a five-phase approach, as follows: Phase 1: item generation based on expert opinion, relevant literature and previous surveys; Phase 2: content validity assessed by experts for relevance and clarity (epidemiologists, dietitians, chefs); Phase 3: face validity and inter-item reliability; Phase 4: criterion validity using a 7-day food and culinary record; and Phase 5: test stability and inter-item reliability. The content validity index for scale and item level values provided evidence of the content validity for relevance and clarity. Criterion validity analysis showed intraclass correlation coefficients ranged from 0.31−0.69. Test−retest reliability coefficients ranged from 0.49−0.92, with ƙ values > 0.44. Overall Cronbach’s alpha was 0.90. In conclusion, the HCFQ is a promising tool with sound content and face validity, substantial criterion validity, and adequate reliability. This 174-item HCFQ is the first questionnaire to assess how often people cook and which cooking methods they use at home.

Physical Activity Assessment and Promotion in Clinical Settings in the United States: A Scoping Review

OBJECTIVE

The purpose of this scoping review was to systematically examine interventions that focused on physical activity assessment and promotion in clinical settings in the United States.

DATA SOURCES

A literature search was performed in 6 major databases to extract published peer-reviewed studies from 2008 to 2019.

INCLUSION AND EXCLUSION CRITERIA

Interventions with practicing health professionals in the United States who performed physical activity assessment and promotion with adult patients 18 years of age and older. Studies were excluded if they were published in non-English, observational or case study designs, or gray literature.

DATA EXTRACTION

Studies were screened and coded based on the population, intervention, comparison, outcomes and study setting for scoping reviews (PRISMA-ScR) framework. Of 654 studies that were identified and screened for eligibility, 78 met eligibility criteria and were independently coded by two coders.

DATA SYNTHESIS

Data were synthesized using qualitative and descriptive methods.

RESULTS

Forty-three of the included studies were randomized controlled trials with a majority being delivered by physicians and nurses in primary care settings. Fifty-six studies reported statistically significant findings in outcome measures such as anthropometrics and chronic disease risk factors, with 17 demonstrating improvements in physical activity levels as a result of the interventions.

CONCLUSION

The assessment and promotion of physical activity in clinical settings appears to be effective but warrants continued research.

Teaching Kitchens in the Learning and Work Environments: The Future Is Now

The learning and working environments of today's hospitals and health systems are designed to predict, diagnose, treat, and manage disease. However, the food environments in these settings are often extraordinarily unappealing, unhealthy, and can adversely impact the well-being of health professionals. What if future health-care sites were designed as showrooms of the most appealing and nutritious foods? What if future cafeterias included ventilated "Teaching Kitchens" as extensions to the everyday "grab and go" check-out lines? What if health-care providers, trainees, staff, and community members had access to foods that were healthy, delicious, affordable, sustainable, and easy to prepare? Most importantly, what if health professionals learned to make these healthy, delicious recipes as part of their required training? "See one, do one, teach one" could become, "See one, taste one, make one, teach one". Teaching Kitchens could serve as both learning laboratories and clinical research centers, whereby teaching kitchen curricula could be tested, through sponsored research, for their impact on behaviors, clinical outcomes, and costs. What if spaces adjacent to Teaching Kitchens were designated "Mindful Eating Spaces," where self-selected patrons could enjoy a "Culinary Feast alongside a Technological Fast" in an effort to carve out a brief oasis of mindful, resilience-building reflection during any given day? This article describes the rationale for and necessary components of such a futurist "Teaching Kitchen" within future working and learning environments. Importantly, if and when Teaching Kitchens are built within health-care settings, they may serve as catalysts of personal and societal health enhancement for all.

Process Evaluation of a Nutrition and Lifestyle Behavior Peer Support Program for Adults with Metabolic Syndrome

Metabolic Syndrome (MetS) is a cluster of risk factors that increases the risk for diabetes and cardiovascular diseases. Lifestyle intervention is the gold standard of MetS management and prevention. Despite the growing positive influence of peer support-based interventions on management of various chronic diseases, its potential among adults with MetS has not been elucidated. We describe the development and process evaluation of a nutrition and lifestyle behavior “PEeR SUpport program for ADults with mEtabolic syndrome” (PERSUADE) using a systematic five-step approach—(i) review of evidence; (ii) focus group discussions; (iii) behavioral matrix development; (iv) module development; and (v) feasibility and process evaluation. High program adherence was recorded with 81.3% of participants attending all peer sessions. Participants’ content satisfaction score was high (93.3%) while peer leadership score was satisfactory (70.0%). There were significant reductions in all anthropometric and metabolic parameters assessed post intervention, except for diastolic blood pressure. Significant correlations were found between reductions in body fat and triglyceride, and content satisfaction. Peer leadership was only significantly correlated with reduction in triglyceride. Future studies can explore aspects of module interactivity, use of social media, and other means to stimulate consistent engagement of participants, as well as extending the implementations to other lifestyle-related diseases.

Lifestyle Medicine-Focused Shared Medical Appointments to Improve Risk Factors for Chronic Diseases and Quality of Life in Breast Cancer Survivors

OBJECTIVES

Poor lifestyle choices play a significant role in the development and progression of preventable chronic diseases, including cancer. In this study, we evaluate the effectiveness of a comprehensive lifestyle medicine intervention on chronic disease risk factors and quality of life in breast cancer survivors.

DESIGN

This is a retrospective review of a clinical program from January 2016 to July 2017.

SETTINGS/LOCATION

It includes seven 2-h group medical visits held every other week at an outpatient wellness facility.

SUBJECTS

Eligible participants are breast cancer survivors who have completed treatment, including those who remain on hormonal therapy.

INTERVENTION

Patients receive education and experience in nutrition, culinary medicine, physical activity, and stress relief practices.

OUTCOME MEASURES

Participants' weight, body mass index (BMI), body fat mass, lean body mass, and percent body fat were measured at visit 1 and visit 7. Standard validated questionnaires were used to measure perceived stress, depression, patient activation, physical and mental quality of life, dietary fat consumption, and dietary fruit, vegetable, and fiber consumption.

RESULTS

A total of 31 patients participated in the group visits. Pre-post comparison data were not available for 10 patients. More than three-quarters of the 21 breast cancer survivors who attended 5 or more of the 7 group visits and provided data at the first and the last group visit decreased their body weight. On average, patients lost 4.9 pounds (-2.6%, p < 0.01), and their BMI decreased by 0.8 kg/m² (-2.5%, p < 0.01). Changes in psychosocial variables of perceived stress, depression, patient activation, and quality of life trended in a positive direction, but did not reach statistical significance. Patients reported a significant decrease in average weekly fat consumption (-31.5%, p < 0.01). Most patients found the program educational and enjoyable, and nearly half of them described it as life changing.

CONCLUSIONS

Breast cancer survivors could employ the prescribed lifestyle modifications to produce clinically relevant health benefits. Interdisciplinary teams of health care professionals may help breast cancer survivors with chronic diseases implement evidence-based, individualized, and effective lifestyle prescription through group medical visits.

Comprehensive Lifestyle Modification Intervention to Improve Chronic Disease Risk Factors and Quality of Life in Cancer Survivors

OBJECTIVES

Healthy lifestyle modifications, including weight management, regular physical activity, prudent diet, and stress relief, have been identified as key components of tertiary cancer prevention. In this study, we evaluate the effectiveness of a comprehensive, lifestyle medicine intervention, Lifestyle 180^®, on chronic disease risk factors and quality of life in cancer survivors.

DESIGN

Retrospective subgroup analysis of a clinical program.

SETTINGS/LOCATION

An outpatient medical facility.

SUBJECTS

Lifestyle 180 participants with a diagnosis of past cancer.

INTERVENTION

Sixty-four hours of intensive nutrition, culinary medicine, physical activity, and stress relief practices over a 6-month period, with 9- and 12-month follow-up.

OUTCOME MEASURES

Pre-postanalysis (baseline vs. 12 months) included biometrics: weight, body mass index (BMI), waist circumference, and blood pressure; standard laboratory tests: lipids, C-reactive protein, fasting insulin/glucose, and insulin resistance; and empirically validated questionnaires: perceived stress, depression, and quality of life.

RESULTS

Fifty-eight cancer survivors participated in Lifestyle 180. Average age was 63 years, roughly 75% of participants were female, and the greatest majority had a diagnosis of breast, prostate, or skin cancer. Diagnosis of hyperlipidemia, hypertension, diabetes, and prediabetes presented in 47%, 57%, 22%, and 50% of patients, respectively. Forty-five percent of patients were obese, 24% were overweight, and 16% were depressed. At 12 months, participants lost an average of 14 pounds (-6.6%, p < 0.001) and 2.6 inches off their waist (-5.9%, p < 0.001). BMI decreased significantly by an average of 2.4 kg/m² (-6.8%, p < 0.001). Significant decreases from well-managed baseline levels also occurred in most measured biomarkers (average change: high-density lipoprotein +3.3 mg/dL, p < 0.05; triglycerides -23.0 mg/dL, p < 0.01; C-reactive protein -1.3 mg/L, p < 0.01; fasting insulin -4.2 μU/mL, p < 0.05; and homeostasis model assessment-insulin resistance -1.5, p < 0.01; n = 40). Changes in psychosocial variables included significant improvements in perceived stress (-20%, p < 0.01) and quality of life (+54%, p < 0.001). We were unable to detect a difference in depressive symptoms.

CONCLUSIONS

Cancer survivors participating in a comprehensive intervention could employ the prescribed lifestyle modifications to produce clinically relevant health and quality-of-life benefits. These data support the American Cancer Society (ACS) and American Society of Clinical Oncology (ASCO) recommendations to incorporate healthy lifestyle modifications into long-term cancer survivorship care.

Interrelationship of canonical and non-canonical Wnt signalling pathways in chronic metabolic diseases

Chronic diseases account for approximately 45% of all deaths in developed countries and are particularly prevalent in countries with the most sophisticated and robust public health systems. Chronic metabolic diseases, specifically lifestyle-related diseases pertaining to diet and exercise, continue to be difficult to treat clinically. The most prevalent of these chronic metabolic diseases include obesity, diabetes, non-alcoholic fatty liver disease, chronic kidney disease and cardiovascular disease and will be the focus of this review. Wnt proteins are highly conserved glycoproteins best known for their role in development and homeostasis of tissues. Given the importance of Wnt signalling in homeostasis, aberrant Wnt signalling likely regulates metabolic processes and may contribute to the development of chronic metabolic diseases. Expression of Wnt proteins and dysfunctional Wnt signalling has been reported in multiple chronic diseases. It is interesting to speculate about an interrelationship between the Wnt signalling pathways as a potential pathological mechanism in chronic metabolic diseases. The aim of this review is to summarize reported findings on the contrasting roles of Wnt signalling in lifestyle-related chronic metabolic diseases; specifically, the contribution of Wnt signalling to lipid accumulation, fibrosis and chronic low-grade inflammation.

Description and implementation of U-Turn Medical, a comprehensive lifestyle intervention programme for chronic disease in the sport and exercise medicine setting: pre-post observations in 210 consecutive patients

BACKGROUND

Non-communicable disease (NCD) is increasing, but management remains mostly curative, disease-centred and focused on single interventions. We describe the development and implementation of a patient-centred, comprehensive, multidisciplinary lifestyle intervention programme (LIP) for patients with NCD in the sport and exercise medicine (SEM) setting (part 1) and present preliminary observational data (part 2).

METHODS

Part 1 is a description of the programme development and implementation. In part 2, 210 participants with NCD underwent a 12-week LIP (U-Turn Medical). Physiological, functional and metabolic outcomes were assessed at baseline and at completion.

RESULTS

84% of patients had two or more comorbidities, requiring additional considerations for exercise rehabilitation. On completion, there were decreases in % body fat (29.8±6.7% vs 28.5±6.6%), waist (100.2±16.2 vs 97.3±14.8 cm) and hip circumference (105.4±13 vs 104±12 cm), resting heart rate (74.2±13.4 vs 71.4±11.9 bpm), resting systolic blood pressure (125.7±16.1 vs 120.1±13 mm Hg) and cholesterol (4.7±1.2 vs 4.3±0.9 mmol/L), low-density lipoprotein (3±0.9 vs 2.7±0.8 mmol/L) and triglyceride (1.4±0.7 vs 1.3±0.6 mmol/L), and increases in flexibility (12.1±11.6 vs 16.1±10.8 cm) and 6 min walk distance (559.4±156.6 vs 652.3±193.6 m; all p<0.05).

CONCLUSIONS

A 12-week comprehensive, patient-centred LIP can be implemented successfully in the SEM setting in patients with NCDs with multiple comorbidities. Observed results show improvements in the majority of outcome variables.

Beliefs about preventive care, individual health, and lifestyle change among low-income African American women at risk for diabetes

Focus groups were held to better understand conceptions of disease prevention among low-income African American women at risk for diabetes. Mental calm was associated with health more than nutrition, exercise, or social connection. This finding suggests that prioritizing stress reduction will help with successful implementation of community holistic diabetes prevention programs.

Genetic determinants of voluntary exercise

Variation in voluntary exercise behavior is an important determinant of long-term human health. Increased physical activity is used as a preventative measure or therapeutic intervention for disease, and a sedentary lifestyle has generally been viewed as unhealthy. Predisposition to engage in voluntary activity is heritable and induces protective metabolic changes, but its complex genetic/genomic architecture has only recently begun to emerge. We first present a brief historical perspective and summary of the known benefits of voluntary exercise. Second, we describe human and mouse model studies using genomic and transcriptomic approaches to reveal the genetic architecture of exercise. Third, we discuss the merging of genomic information and physiological observations, revealing systems and networks that lead to a more complete mechanistic understanding of how exercise protects against disease pathogenesis. Finally, we explore potential regulation of physical activity through epigenetic mechanisms, including those that persist across multiple generations.
