The Healthspan Project: A Retrospective Pilot of Biomarkers and Biometric Outcomes after a 6-Month Multi-Modal Wellness Intervention.

Wellness-centric proactive healthcare is increasingly sought after, with individuals frequently embracing complementary modalities to achieve this goal. In this six-month study, healthy adult participants (n = 25) received specific therapies, including whole-body cryotherapy, infrared sauna, and photobiomodulation, along with guidance on physical activity, diet, and alcohol intake. Serum biomarkers were measured for all participants, while a subset also received biometric assessments for body composition (n = 10) and heart rate variability (n = 7). Over the course of the study (mean (SD) follow-up days = 174 (130)), participants exhibited significant improvements in health. LDL cholesterol (-9.77 (15.43) md/dL) and hsCRP (-1.75 (2.66) mg/L) decreased significantly (p < 0.05). HbA1c increased slightly (p < 0.05), but the effect size was small (0.12 (0.13)%). The body composition subset lost overall body weight (-3.29 (3.75) kg), primarily body fat, while preserving lean muscle mass (p < 0.05). Heart rate variability increased for those with existing cardiovascular risk factors (p < 0.05). In conclusion, participation in the multimodal Healthspan protocol is associated with substantial improvements in health-related biomarkers and biometrics.

Exercise professional education, qualifications, and certifications: a content analysis of job postings in the United States.

Introduction: Growth in the field of clinical exercise science and the potential impacts on overall health and wellbeing have driven the need for qualified, clinically trained, exercise professionals. And yet, it is not well understood what specific credentials employers are seeking when hiring exercise professionals. Purpose: The purpose of the study was to examine the qualification requirements for professionals seeking employment in exercise science, exercise physiology, kinesiology or equivalent fields. Methods: Search platforms Indeed.com and USAJobs.gov were examined within a two week period in 2022. Search terms included "Exercise Physiology", "Exercise Science", "Exercise Professional", "Exercise Prescription", "Exercise Specialist", and "Kinesiology". Results: A total of n = 739 jobs were retrieved and n = 615 jobs were included: Exercise Science (n = 227), Kinesiology (n = 210), Exercise Physiology (n = 91), Exercise specialist (n = 53), and Exercise prescription (n = 32). Over 70% of the jobs analyzed required a bachelor's degree with the remainder requiring various levels of education. The primary certification required was personal trainer (n = 94), followed by strength and conditioning specialist (n = 33), clinical exercise physiologist (n = 26), group exercise (n = 17), exercise specialist (n = 10), and exercise physiologist (n = 5). Four job focus areas were determined: academic teaching and research, general fitness and worksite wellness, athletic performance and rehabilitation, clinical exercise specialist all with varying levels of degree and certification requirements. Discussion: Job postings related to exercise related professions are varied across the United States with wide-ranging education, credentialing and certification requirements. These findings indicate the timely need for outreach to employers to highlight changing credentialing requirements due to evolving accreditation standards.

Nutrition Interventions on Muscle-Related Components of Sarcopenia in Females: A Systematic Review of Randomized Controlled Trials.

Sarcopenia is a skeletal muscle disease categorized by low muscle strength, muscle quantity or quality, and physical performance. Sarcopenia etiology is multifaceted, and while resistance training is widely agreed upon for prevention and treatment, disease progression is also highly related to poor diet. The incidence of sarcopenia appears sex-specific and may be increased in females, which is problematic because dietary quality is often altered later in life, particularly after menopause. Identifying effective nutrition or supplementation interventions could be an important strategy to delay sarcopenia and related comorbidities in this vulnerable population. This systematic review examined randomized controlled trials (RCTs) of nutrition strategies on muscle-related components of sarcopenia in middle-aged and older females. A protocol was registered (PROSPERO CRD42022382943) and a systematic search of MEDLINE and CINAHL was undertaken. RCTs from 2013 to 2023 that assessed nutrition-only interventions on muscle mass, muscle strength, and physical function in female participants were included. Fourteen RCTs were included based on selection criteria. Study designs and interventions were heterogeneous in supplementation type and amount, age, and duration. Six RCTs reported beneficial effects of protein, Vitamin D, Vitamin D and Magnesium (Mg), and fish oil on muscle protein synthesis, muscle strength, and/or muscle function. Eight studies that examined various protein interventions, VitD alone, Mg alone, and dairy derivatives did not demonstrate any effect. Exercise appeared to modulate results in several studies. Nutrition interventions alone are likely to have a limited but positive effect on muscle-related components of sarcopenia in females. Current evidence suggests that a combination of dietary intervention and exercise is likely to be key to preventing and treating sarcopenia in middle aged and older females and there is a need for well-designed nutrition based studies in this population.

Performance Medicine: a novel and needed paradigm for proactive health care.

Performance Medicine is an emerging clinical practice that holds immense promise for advancing preventive health. To date, however, the concept remains imprecise, disorganized, and commercialized. The purpose of this perspective article is to define characteristics, core tenets, and practice standards to help build a common framework. We define performance broadly as "one's capacity to bring energy and attention to what matters most in a given moment". Performance Medicine, therefore, is predicated on the thesis that the critical practices that enhance one's daily wellbeing simultaneously increase both lifespan and healthspan. As a clinical practice, Performance Medicine is proactive and preventive. It focuses on the immediate and actionable strategies to address one's physical, mental, and emotional capabilities every day. The practice employs a values-centered approach that begins with a discovery process to elucidate the client's deeply held beliefs about their health status, life mission and goals, vision for optimal wellbeing, and motivations for change. Subsequent diagnostics and therapies combine evidence-based practices from multiple medical specialties including internal medicine, sports medicine, obesity medicine, integrative medicine, and others. This is complemented by the most recent scientific advancements in nutrition, exercise physiology, sleep, and recovery. The Performance Medicine prescription incorporates a personalized combination of lifestyle-based behavior change practices, evidence-based diagnostics and risk reduction therapies, ongoing monitoring, and community support. Finally, the iterative and incremental process towards enhanced and sustained health is guided and supported by a trusted partnership between the client and a team of expert practitioners and coaches.

Physician Nutrition Advice and Referrals to Registered Dietitians.

PURPOSE: This study aims to examine the frequency and content of healthcare providers' nutrition recommendations and referrals Registered Dietitian Nutritionists (RDN). METHODS: Physicians, physician assistants, nurses, and other providers (> 18 years of age) currently practicing primarily in the United States received an email survey that assessed dietary recommendations for diabetes, hypertension, dyslipidemia, overweight/obesity, and general wellbeing, frequency and comfort level of providing nutrition advice, and RDN referrals. Chi-square and Student's t-tests were used for analysis. RESULTS: 154 physicians (61%), registered nurses/nurse practitioners/physician assistants (19.5%), and other providers (19.5%) were included. Those with nutrition education gave nutrition advice more than those without for some, but not all, conditions (P = .01). The Mediterranean diet was most frequently recommended, except for hypertension. The DASH diet was recommended to 47.7% of patients with hypertension. More providers gave dietary advice than referred to RDNs. Dietary advice was associated with RDN referrals for diabetes (P = .01) and wellbeing (P = .05). Providers with an RDN in their practice provided advice for diabetes more than those without (P = .01). CONCLUSION: Healthcare providers gave nutrition recommendations consistent with evidence-based guidance. RDN referrals occur in conjunction with dietary recommendations, not as replacement.

The Benefits of Physical Activity for People with Obesity, Independent of Weight Loss: A Systematic Review.

Purposeful weight loss continues to be the primary focus for treating obesity. However, this strategy appears to be inadequate as obesity rates continue to rise and a myriad of benefits of physical activity that affect multiple health outcomes related to obesity and associated comorbidities are not integrated into treatment strategies. There are emerging correlational data in individuals with obesity that demonstrate physical activity can be beneficial to many critical health markers, independent of weight loss or changes in BMI. This systematic review investigates interventional studies that examine health markers, independent of weight loss, in individuals with obesity. Fourteen studies were identified that utilized a variety of physical activity interventions with primary endpoints that included cellular, metabolic, systemic and brain health outcomes. The review of the literature demonstrates that for individuals with obesity, there are both small-scale and large-scale physiologic benefits that occur with increased physical activity of various modalities. Focusing on these benefits, rather than a narrow focus of weight loss alone, may increase physical activity behavior and health for individuals with obesity.

Vitamin D deficiency associated with risk of prediabetes among older adults: Data from the National Health and Nutrition Examination Survey (NHANES), 2007-2012.

AIM: To examine the association between vitamin D (25(OH)D) deficiency and risk of prediabetes in Americans 50+ years of age. MATERIALS AND METHODS: This was a cross-sectional analysis of NHANES (2007-2012) subjects aged 50+ years, free of kidney/liver diseases and diabetes. Prediabetes was defined as: HbA1c level 5.7%-6.4%, or fasting plasma glucose level 100-125 mg/dL, or Oral Glucose Tolerance Test result 140-199 mg/dL, with no laboratory value in the diabetic range. The comparison group had normal glucose tolerance (NGT) with no marker in the prediabetes/diabetes range. Total serum 25(OH)D levels were deficient at <50 nmol/L, insufficient 50-75 nmol/L, and sufficient >75 nmol/L. Logistic regression included strata, cluster and weight variables. Models were adjusted for body mass index (BMI), ethnicity, age and gender. RESULTS: The final sample was 2286 adults, predominantly White (80.4%) and female (56.6%), with a mean age of 62.3 years. Within the sample, 1387 had prediabetes (59.1%) and 899 were NGT (40.9%). Individuals classified within a lower serum vitamin D category were more likely to have prediabetes (p = 0.03). Those with 25(OH)D deficiency were more likely to have prediabetes compared to 25(OH)D sufficient individuals (crude OR = 1.48, 95% CI 1.15-1.91), and this association remained significant after adjustment for ethnicity, BMI, age and gender (aOR = 1.39, 95% CI 1.02-1.89). There was no effect modification by BMI, gender or ethnicity. CONCLUSIONS: Vitamin D status was associated with risk of prediabetes in this sample of Americans 50+ years of age. Future research should seek to understand the potential mechanistic relationship between vitamin D and prediabetes.

Move It or Lose It: Summarizing Peer-reviewed Evidence for Practicing What You Preach.

Physically active health care providers are more likely to provide physical activity (PA) counseling to their patients, but barriers in PA counseling exist. Common barriers include knowledge, time constraints, lack of reimbursement, as well as lack of personal habits. This article will summarize evidence-based knowledge regarding provider PA habits as a means of improving rapport, compliance, and empathy for patients when prescribing PA. Clinical pearls for successful PA counseling scenarios also will be discussed.

Identifying elements for a comprehensive paediatric cardiac rehabilitation programme.

INTRODUCTION: The aim of this study was to identify relevant content among four important domains for the development and structure of a paediatric cardiac rehabilitation curriculum for young patients with congenital heart disease using a consensus approach. METHODS: A three-round e-Delphi study among congenital heart disease and paediatric exercise physiology experts was conducted. Round 1, experts provided opinions in a closed- and open-ended electronic questionnaire to identify specific elements necessary for inclusion in a paediatric cardiac rehabilitation programme. Round 2, experts were asked to re-rate the same items after feedback and summary data were provided from round 1. Round 3, the same experts were asked to re-rate items that did not reach consensus from round 2. RESULTS: Forty-seven experts were contacted via e-mail to participate on the Delphi panel, 37 consented, 35 completed round 1, 29 completed round 2, and 28 completed the final round. After round 2, consensus was reached in 55 of 60 (92%) questionnaire items across four domains: exercise training, education, outcome metrics, and self-confidence. CONCLUSION: This study established consensus towards programme structure, exercise training principles, educational content, patient outcome measures, and self-confidence promotion. By identifying the key components within each domain, there is potential to benchmark recommended standards and practice guidelines for the development of a paediatric cardiac rehabilitation curriculum to be used and tested by exercise physiologists, paediatric and adult congenital cardiologists, and other healthcare team members for optimising the health and wellness of paediatric patients with congenital heart disease.

Identifying Key Physical Activity Categories and Topics to Include in Health Professional Training Programs.

Phenomenon: Healthcare is an important sector in promoting physical activity (PA). However, few health professional training programs include PA, nor does standardized guidance exist on implementing it in the curriculum. This study aimed to consolidate health professional expert opinion on key PA categories and topics that should be included in the curriculum of health professional training programs. Approach: A three-round, modified e-Delphi process examined the opinions of 73 experts from seven health professions (clinical nutrition, exercise physiology, medicine, nursing, occupational therapy, physical therapy, physician assistants). In Round 1, panelists reported importance, ranked, and scored five broad PA categories, and responded to open-ended prompts for additional categories. In Round 2, panelists received summary feedback, re-ranked and re-scored PA categories, and suggested key PA topics within the five categories. In the final round, panelists viewed, ranked, and scored the PA topics. Findings: Expert panelists felt that all PA categories were important, with Health Behavior Change ranking the highest (98.7%) followed by Cellular and Systemic Implications of Exercise, Clinical Exercise Physiology, and PA and Public Health. The Administrative Aspects of Integrating PA into Health Systems ranked least important (48.0%). A consensus on the key PA categories was considered reached after two rounds. Five to eight specific PA topics were generated within each PA category and ranked in order of importance. Insights: These findings highlight several key PA categories and topics that can serve as a foundation for a diverse number of health professional training programs.

Translating Urban Walkability Initiatives for Older Adults in Rural and Under-Resourced Communities.

The built environment can promote physical activity in older adults by increasing neighborhood walkability. While efforts to increase walkability are common in urban communities, there is limited data related to effective implementation in rural communities. This is problematic, as older adults make up a significant portion of rural inhabitants and exhibit lower levels of physical activity. Translating lessons from urban strategies may be necessary to address this disparity. This review examines best practices from urban initiatives that can be implemented in rural, resource-limited communities. The review of the literature revealed that simple, built environment approaches to increase walkability include microscale and pop-up infrastructure, municipal parks, and community gardens, which can also increase physical activity in neighborhoods for urban older adults. These simple and cost-effective strategies suggest great potential for rural communities.

Bridging the gap between clinicians and fitness professionals: a challenge to implementing exercise as medicine.

OBJECTIVE: Health clubs (HC) and personal trainers (PT) are traditional outlets for the promotion of physical activity (PA) and exercise programming. As physicians are increasingly being called on to write exercise prescriptions for their patients, this study sought to investigate the level of integration between the healthcare and fitness systems. DESIGN: An internet study was designed with five domains to understand physicians': (1) overall perception of HC, (2) appropriateness and recommendation of HC and PT to their patients, (3) attitude regarding specific aspects of HC, (4) support of patient participation in HC sponsored exercise and (5) elements of HC that physicians would like to know for referral. METHODS: An electronic survey was sent to members of two mailing lists of primary care and sports medicine specialty physicians during 2011-2012. RESULTS: On a Likert scale of 1-10 412 physicians reported being familiar with HC (8.9±2.1), indicated a favourable view of HC (7.9±2.2), and believe HC to be an appropriate venue for their patients (7.5±2.3). However, physicians only recommend HC to 41%±28% of their patients and PT for only 21%±21.6% of patients. Physicians ranked expense and convenience as the most problematic elements of HC (8.1±2.1 and 6.3±2.5, respectively). 72% of physicians indicated cost as most concerning when recommending a specific HC. CONCLUSION: HC and PT are a significant implementation system for the promotion of physical activity, yet physicians are concerned with several elements of HC and are not adequately relying on this partnership to promote physical activity to their patients.

Improved Access to and Impact of Registered Dietitian Nutritionist Services Associated with an Integrated Care Model in a High-Risk, Minority Population.

BACKGROUND: Integrated health care models create opportunities for registered dietitian nutritionists (RDNs) to provide nutrition-related care and engage in multidisciplinary teams to improve clinical outcomes. While benefits of integrated care (IC) have been reported, little is known about the impact of the RDN within an IC model. OBJECTIVE: Our primary objective was to identify whether IC vs traditional care (TC) increases the number of RDN patient visits. Our secondary objective was to evaluate clinical outcomes of patients seeing an RDN vs not, regardless of care model. DESIGN: This was a retrospective cohort study. PARTICIPANTS/SETTING: Patients were aged 3 to 94 years and from a patient-centered medical home in Boston, MA. MAIN OUTCOME MEASURES: We measured 3-month total and average number of patients seen by the RDN in TC vs IC. Changes in adult hemoglobin A1c, weight, and pediatric body mass index (measured as kg/m2) among high-risk patients seen by an RDN compared to patients not seen by an RDN. STATISTICAL ANALYSIS: Data were obtained from electronic medical records and analyzed utilizing Mann-Whitney U test, analysis of covariance, and paired sample t tests. RESULTS: The RDN saw 145 patients (137 adult, 8 pediatric) in the TC model compared to 185 patients (135 adult, 50 pediatric) in the IC model. Mean number of patients seen per session was 3.20 in the TC model vs 4.63 in the IC model (P=0.004). Adult hemoglobin A1c within-group differences decreased by 0.42%±1.49% (P=0.007) for patients seen by an RDN and decreased 0.15%±1.47% (P=0.012) for patients not seen by an RDN. Adult weight within-group differences decreased 1.0±7.2 kg (P=0.15) for patients seen by a RDN and increased 0.1±5.6 kg (P=0.70) for patients not seen by a RDN. Pediatric BMI showed no change between or within groups. CONCLUSIONS: The IC model increased 3-month total number of patients seen by an RDN. High-risk patients who saw an RDN had a significant decrease in hemoglobin A1c.

Practice patterns, counseling and promotion of physical activity by sports medicine physicians.

OBJECTIVES: This study examined sports medicine physicians with an established interest in physical activity to investigate attitudes surrounding exercise, physical activity and patient-counseling behavior. The degree to which physicians' personal knowledge of physical activity and related resources, involvement with common activities, and perceived barriers were assessed. DESIGN: An internet survey was designed in four domains: (1) counseling behavior, (2) tools and resources, (3) appropriateness of common physical activities for patients and (4) barriers. METHODS: The survey was sent to 3570 members of two electronic mailing lists - Institute of Lifestyle Medicine, Boston, MA and The American College of Sports Medicine. Surveys were emailed during 2011-2012 and analyzed in 2013-2014. Each survey contained 39 questions. RESULTS: The response rate of the surveys was 16%. Of 412 physicians, 74% regularly recommended physical activity, 66% talked about exercise with patients, and 49% included as a vital sign. Only 26% of physicians provided a written exercise prescription. ACSM's Exercise is Medicine® (37%) was the most popular resource. Walking, followed by aerobic activity, strength training and cycling were the most recommended forms of activity and were associated with physicians' personal experiences. The most potent inhibitor was time. CONCLUSIONS: Physicians with an interest in exercise and physical activity recognize the importance of recommending and counseling patients on exercise and physical activity. Physician counseling was associated with personal familiarity with physical activity. Increasing knowledge and experience with exercise, physical activity and counseling behavior is an important component to encourage physical activity assessment and promotion by sports medicine physicians.

A parallel curriculum in lifestyle medicine.

BACKGROUND: Less than 50 per cent of US primary care doctors routinely provide guidance to their patients on lifestyle behaviours such as diet, physical activity or weight control, despite the prediction by the World Health Organization that by 2020, two-thirds of disease worldwide will be the result of poor lifestyle choices. This gap in patient-clinician dialogue is perhaps the result of a lack of structured training in medical school surrounding the components of lifestyle medicine. CONTEXT: Although Harvard Medical School does have a required course in nutrition, there are no requirements for the other components of lifestyle medicine, including physical activity, behaviour change and self-care. INNOVATION: Since 2009 Harvard Medical School has addressed this absence in the curriculum by developing a student-led, faculty member-advised, parallel curriculum in lifestyle medicine. Medical student participants were invited to take part in anonymous questionnaires between 2009 and 2013, which gathered data about personal ability and attitude in counselling patients on lifestyle behaviours, as well as subjective data on the curriculum content and applications to effective medical practice. Less than 50 per cent of US primary care doctors routinely provide guidance to their patients on lifestyle behaviours IMPLICATION: Each year, students have pointed to a lack of lifestyle medicine knowledge because of a gap in the traditional curriculum surrounding topics such as physical activity, nutrition and behaviour-change strategies, and indicated that the inclusion of this knowledge and these skills was an important component of medical education. Although participation is currently voluntary, this is the first such curriculum of this type and addresses a critical gap in undergraduate medical education.

The effect of before school physical activity on child development: A study protocol to evaluate the Build Our Kids Success (BOKS) Program.

INTRODUCTION: Most childhood physical activity interventions focus on reducing childhood obesity with varying success, indicating that body mass index (BMI) may be a limited marker of health in children. To better understand overall childhood health and wellbeing, this study is investigating BOKS (Build Our Kids Success), an established ongoing before-school physical activity program, to evaluate students' physical health, mental health, cognitive capacity, and academic performance. DESIGN AND METHODS: The study is a non-randomized controlled trial with 26 elementary and middle schools in 3 Massachusetts communities, including first through eighth grade (aged 5-14) students, their parents, and teachers. Data collection is occurring during the 2015-2016 school year. Physical fitness is being assessed via 400m run and anthropometrics via height and weight measures (BMI). Psychosocial outcomes are being assessed via student, parent, and teacher survey and include nutrition, daily activities, emotional and relationship scales, bullying and victimization, vitality and energy, student engagement, stress, positive affect, self-efficacy and life satisfaction. Academic performance is reported by grades. Statistical methods include a psychometric evaluation of study measures, Pearson correlations, Student's t-tests, ANOVA/ANCOVA and multivariate linear regression including multilevel modeling analyses to account for the hierarchical organization of the data. DISCUSSION: This study is investigating a before school physical activity program on parameters of physical health, mental health, cognitive capacity, and academic performance by employing a novel triad approach, correlating the input of the child, parent, and teacher. Outcomes will evaluate the effectiveness of a before school physical activity program in elementary and middle schools and potentially provide valuable information for schools looking to institute innovative physical activity programs.

Lifestyle Medicine Education.

The actual causes of premature adult deaths, the preponderance of noncommunicable chronic diseases, and their associated costs are related to unhealthy behaviors, such as poor nutrition, physical inactivity, and tobacco use. Although recommended as the first line of prevention and management, providers often do not provide behavioral change counseling in their care. Medical education in lifestyle medicine is, therefore, proposed as a necessary intervention to allow all health providers to learn how to effectively and efficiently counsel their patients toward adopting and sustaining healthier behaviors. Lifestyle medicine curricula, including exercise, nutrition, behavioral change, and self-care, have recently evolved in all levels of medical education, together with implementation initiatives like Exercise is Medicine and the Lifestyle Medicine Education (LMEd) Collaborative. The goal of this review is to summarize the existing literature and to provide knowledge and tools to deans, administrators, faculty members, and students interested in pursuing lifestyle medicine training or establishing and improving an LMEd program within their institution.

Including lifestyle medicine in undergraduate medical curricula.

PURPOSE: Currently, there is no model to integrate the discipline of lifestyle medicine (LM) into undergraduate medical education. Furthermore, there are no guidelines, validated assessment tools, or evaluation or implementation plans in place. BACKGROUND: The World Health Organization predicts that by 2020, two-thirds of disease worldwide will be the result of poor lifestyle choices. Fewer than 50% of US primary care physicians routinely provide specific guidance on nutrition, physical activity, or weight control. METHODS: We are establishing a plan to integrate LM into medical school education in collaboration with the investing stakeholders, including medical school deans and students, medical curriculum developers and researchers, medical societies, governing bodies, and policy institutes. Three planning and strategy meetings are being held to address key areas of focus - with a particular interest in nutrition, physical activity, student self-care, and behavior change - to develop specific implementation guidelines and landmarks. RESULTS: After the first two meetings, the proposed areas of focus were determined to be: 1) supporting of deans and key personnel, 2) creation of federal and state policy commitments, 3) use of assessment as a driver of LM, 4) provision of high-quality evidence-based curricular material on an easily navigated site, and 5) engaging student interest. Implementation strategies for each focus area will be addressed in an upcoming planning meeting in early 2015. CONCLUSION: This initiative is expected to have important public health implications by efficiently promoting the prevention and treatment of non-communicable chronic disease with a scalable and sustainable model to educate physicians in training and practice.
