Public park spaces as a platform to promote healthy living: introducing a HealthPark concept
The concept of Healthy Living (HL) as a primary medical intervention continues to gain traction, and rightfully so. Being physically active, consuming a nutritious diet, not smoking and maintaining an appropriate body weight constitute the HL polypill, the foundation of HL medicine (HLM). Daily use of the HL polypill, working toward optimal dosages, portends profound health benefits, substantially reducing the risk of chronic disease [i.e., cardiovascular disease (CVD), pulmonary disease, metabolic syndromes, certain cancers, etc.] and associated adverse health consequences. To be effective and proactive, our healthcare system must rethink where its primary intervention, HLM, is delivered. Waiting for individuals to come to the traditional outpatient setting is an ineffective approach as poor lifestyle habits are typically well established by the time care is initiated. Ideally, HLM should be delivered where individuals live, work and go to school, promoting immersion in a culture of health and wellness. To this end, there is a growing interest in the use of public parks as a platform to promote the adoption of HL behaviors. The current perspectives paper provides a brief literature review on the use of public parks for HL interventions and introduces a new HealthPark model being developed in Chicago
The Physiologic Benefits of Optimizing Cardiorespiratory Fitness and Physical Activity â From the Cell to Systems Level in a Post-Pandemic World
Cardiovascular (CV) disease (CVD) is a leading cause of premature death and hospitalization which places a significant strain on health services and economies around the World. Evidence from decades of empirical and observational research demonstrates clear associations between physical activity (PA) and cardiorespiratory fitness (CRF) which can offset the risk of mortality and increase life expectancy and the quality of life in patients. Whilst well documented, the narrative of increased CRF remained pertinent during the coronavirus disease 2019 (COVID-19) pandemic, where individuals with lower levels of CRF had more than double the risk of dying from COVID-19 compared to those with a moderate or high CRF. The need to better understand the mechanisms associated with COVID-19 and those that continue to be affected with persistent symptoms following infection (Long COVID), and CV health is key if we are to be able to effectively target the use of CRF and PA to improve the lives of those suffering its afflictions. Whilst there is a long way to go to optimise PA and CRF for improved health at a population level, particularly in a post-pandemic world, increasing the understanding using a cellular-to-systems approach, we hope to provide further insight into the benefits of engaging in PA
Assessing the Value of Moving More-The Integral Role of Qualified Health Professionals
Being physically active or, in a broader sense, simply moving more throughout each day is one of the most important components of an individual's health plan. In conjunction with regular exercise training, taking more steps in a day and sitting less are also important components of one's movement portfolio. Given this priority, health care professionals must develop enhanced skills for prescribing and guiding individualized movement programs for all their patients. An important component of a health care professional's ability to prescribe movement as medicine is competency in assessing an individual's risk for untoward events if physical exertion was increased. The ability to appropriately assess one's risk before advising an individual to move more is integral to clinical decision-making related to subsequent testing if needed, exercise prescription, and level of supervision with exercise training. At present, there is a lack of clarity pertaining to how a health care professional should go about assessing an individual's readiness to move more on a daily basis in a safe manner. Therefore, this perspectives article clarifies key issues related to prescribing movement as medicine and presents a new process for clinical assessment before prescribing an individualized movement program
Assessment of the Effects of Whole Body and Regional Soft Tissue Composition on Bone Strength and Development in Females
Osteoporosis is a major public health concern with origins in childhood and is potentially linked to childhood obesity. This study used novel approaches in bone imaging to characterize skeletal development in girls and to assess the influence of whole body and regional soft tissue composition on bone material, structural and geometric properties, the primary determinants of bone strength, controlling for important covariates such as maturation, diet and physical activity. Prospective analyses were conducted to assess associations between measures of total body fat (TBFM) and android fat masses (AFM) and skeletal muscle fat (SMF) content on bone mineral content, density and strength. The results showed that higher TBFM and AFM were inversely associated with changes in cortical bone sites of the femur and tibia. These findings suggest that gains in abdominal adiposity during the pre- and early- pubertal years may contribute to suboptimal bone development and skeletal fragility later in life. The analyses also showed inverse associations between baseline muscle density of the thigh and calf with 2-year changes in bone strength and bone density of the metaphyseal and diaphyseal sites of the femur and tibia. This paradoxical relationship between SMF and bone outcomes was explained by subsequent analyses showing that girls exhibiting larger gains in muscle density experienced larger increases in bone density and strength compared to girls who did not significantly increase muscle density. These findings suggest that fatty infiltration of skeletal muscle contributes to suboptimal bone development in peri-pubertal girls. Further longitudinal analyses were conducted to examine the individual effects of the muscle-bone unit components on 2-year changes in bone strength. These results showed that muscle size contributed to gains in bone strength, independent of its mechanostat effect on BMC. These results underscore the importance of muscle size for promoting bone development and bone strength during growth. A final set of analyses were conducted to examine the effects of dietary fatty acids on bone development. The results of these analyses suggest that while decreasing intakes of AA n-6 FA may benefit bone health, higher intakes n-3 FAs may benefit tibia bone density development in young girls

Addressing the Nutritional Phenotype Through Personalized Nutrition for Chronic Disease Prevention and Management
The primary focus of public health recommendations related to the prevention of food-related chronic disease has been on the adoption of healthy dietary patterns; however, implementation has been challenging. There has been increasing recognition that an individualâs diet and environment may impact disease susceptibility by affecting the expression of genes involved in critical metabolic pathways. Precision nutrition (PN) has emerged to translate discoveries about diversity in nutrient metabolism between subgroups and the inter-individual variability in the responses to dietary interventions. The overarching goals of PN are to deliver individualized, actionable dietary therapy based on an individualâs nutritional phenotype, created from the integration of genetics, metabolic profile, and environmental factors in order to prevent and treat chronic disease. This review addresses the developments of genome- and omic-driven PN and how they have been used to prevent and treat disease, as well as how they might be integrated into broader clinical practice
The role of diet for prevention and management of hypertension
Purpose of reviewRegular consumption of a diet high in sodium, energy dense foods, fat content, refined carbohydrates, added sugar and low in fruits and vegetables contributes to an increased risk of developing hypertension (HTN) and cardiovascular disease. This review aims to provide a synopsis of evidence-based dietary approaches that have been effective in lowering blood pressure (BP) in pre-HTN and individuals with HTN.Recent findingsRecent dietary recommendations have emphasized overall dietary patterns and its relation between food and BP. The Dietary Approaches to Stop Hypertension (DASH) diet and modifications to the DASH diet, coupled with reductions in sodium intake, show dose-dependent decreases in BP. Implementation of digital lifestyle interventions based on the DASH diet have been effective and show potential for clinical application.SummaryAdopting a diet rich in plant-based foods, whole grains, low-fat dairy products, and sodium intake within normal limits can be effective in the prevention and management of HTN. These diets have been found to be more effective in older adults and hypertensive persons, particularly in studies that provided meals or frequent dietary counseling
