Available in PDF, EPUB and Kindle. Book excerpt: More than 160 million US adults aged 20 years and older are overweight or obese. The greatest increase in the prevalence of overweight and obesity has occurred among young adults aged 18 to 29 years. College students represent a subpopulation at a higher risk for excess weight gain, which is often perpetuated by daily health behaviors, particularly, how time is spent in sleep, sedentary time (SED), and physically active behaviors. This study applied a novel isotemporal substitution model approach to investigate how reallocating time spent in SED activities to sleep and physically active behaviors influenced body mass index (BMI). College-age (20.1±1.5 years) students (n=1,533) of normal weight ((BMI=24.4±4.7 kg/m2) provided self-reported BMI (height and weight), sleep, SED, and physical activity data anonymously through an online survey. Sleep and physical activity (SED and physically active behaviors) were assessed via the Pittsburgh Sleep Quality Index and International Physical Activity questionnaires. Sleep (r=-.070) and moderate-to-vigorous intensity physical activity (MVPA) (r=-.068) behaviors were weakly but significantly associated with BMI (all P.05). SED (r=.043) and light-intensity-physical activity (LPA) (r=-.014) behaviors were not associated with BMI (all P.05). In both the single and partition models, sleep (B=-.223 and B=-.238) and MVPA (B= -.333 and B=-.348) were inversely associated with BMI (all P

Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the origins, determinants and magnitude of the global problem of sedentary behaviour, along with concise yet in-depth solutions for tackling it. As a consequence of major technological advances in modern society, many people find themselves in environments characterized by prolonged sedentary behaviour. Building on the contributions of leading experts in the field, the new edition of this book presents updated knowledge about sedentary behaviour, its medical and public health significance, its correlates and determinants, measurement techniques, and recommendations for addressing this behaviour at the individual, community, environmental, and policy level. The book encompasses current research linking the COVID-19 pandemic to increased levels of sedentary behavior, and it covers global and planetary health aspects of sedentary behavior, highlighting sustainable development goals such as health and well-being for all. Applying a cross-disciplinary methodology, the book avoids considering physical activity and sedentary behavior as a single continuum, which potentially hampers progress in confronting widespread levels of sedentariness. Rather, the book helps readers better understand how sedentary and physically active behavior co-occur and how the two behaviours have distinct contributing factors. Building on the contributions of distinguished international experts in the field, this thorough resource is a valuable asset and challenges professionals, researchers, students, and practitioners alike to adopt new strategies and expand their reach.

Available in PDF, EPUB and Kindle. Book excerpt: Clinical practice related to sleep problems and sleep disorders has been expanding rapidly in the last few years, but scientific research is not keeping pace. Sleep apnea, insomnia, and restless legs syndrome are three examples of very common disorders for which we have little biological information. This new book cuts across a variety of medical disciplines such as neurology, pulmonology, pediatrics, internal medicine, psychiatry, psychology, otolaryngology, and nursing, as well as other medical practices with an interest in the management of sleep pathology. This area of research is not limited to very young and old patientsâ€"sleep disorders reach across all ages and ethnicities. Sleep Disorders and Sleep Deprivation presents a structured analysis that explores the following: Improving awareness among the general public and health care professionals. Increasing investment in interdisciplinary somnology and sleep medicine research training and mentoring activities. Validating and developing new and existing technologies for diagnosis and treatment. This book will be of interest to those looking to learn more about the enormous public health burden of sleep disorders and sleep deprivation and the strikingly limited capacity of the health care enterprise to identify and treat the majority of individuals suffering from sleep problems.

This book was released on 2017 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical activity, sedentary behaviors, and sleep are often associated with cardiometabolic biomarkers commonly found in metabolic syndrome. These relationships are well studied, and yet there are still questions on how each activity may affect cardiometabolic biomarkers. The objective of this study was to examine data from the BeWell24 studies to evaluate the relationship between objectively measured physical activity and sedentary behaviors and cardiometabolic biomarkers in middle age adults, while also determining if sleep quality and duration mediates this relationship. A group of inactive participants (N = 29, age = 52.1 plus or minus 8.1 years, 38% female) with increased risk for cardiometabolic disease were recruited to participate in BeWell24, a trial testing the impact of a lifestyle-based, multicomponent smartphone application targeting sleep, sedentary, and more active behaviors. During baseline, interim (4 weeks), and posttest visits (8 weeks), biomarker measurements were collected for weight (kg), waist circumference (cm), glucose (mg/dl), insulin (uU/ml), lipids (mg/dl), diastolic and systolic blood pressures (mm Hg), and C reactive protein (mg/L). Participants wore validated wrist and thigh sensors for one week intervals at each time point to measure sedentary behavior, physical activity, and sleep outcomes. Long bouts of sitting time (>30 min) significantly affected triglycerides (beta = .15 (plus or minus .07), p

Available in PDF, EPUB and Kindle. Book excerpt: From office jobs and long commutes to passive entertainment like television and video games, humans are sitting more than ever. Though lack of exercise has major health consequences, researchers are now examining the additional and widespread health risk of the simple act of sitting for extended periods. With research from leading scientists, Sedentary Behavior and Health: Concepts, Assessments, and Interventions presents evidence on sedentary behavior, its apparent health risks, and suggestions on measuring and altering this behavior. The highly respected international author team provides an interdisciplinary review of current research, examining scientific, public health, and broader social questions about the implications of sedentary behavior. These topics include humans’ physiological predispositions, exacerbation of current health conditions like obesity and diabetes, and the design and ergonomics of offices and chairs. To examine the many facets of this developing area of study, Sedentary Behavior and Health is divided into five parts: • “Sedentary Behavior Concepts and Context” reviews the physiology of sedentary behavior, investigating current habits from the perspectives of evolution, industrial engineering, and design. • “Sedentary Behavior and Health” explores the relationship between sedentary behavior and several major chronic diseases, including obesity, cardiovascular disease, and low-back pain. • “Measuring and Analyzing Sedentary Behavior” explains research methods for understanding and measuring sedentary behavior in order to recognize patterns and design interventions. • “Sedentary Behavior and Subpopulations” covers issues, risks, and behaviors in groups such as children, working adults, older adults, and minorities. • “Changing Sedentary Behavior” provides methods and recommendations for improvement with environmental, social, community, worksite, and technology-based interventions. Included in this groundbreaking text are learning objectives, key concepts, and study questions to focus attention on key issues and reinforce concepts. Reviews of the literature in the field are presented, many with comparisons in table form, to provide the full scope of research. Sidebars throughout the text apply theoretical concepts to real-world scenarios. Inactivity is mismatched with many aspects of humans’ genetic makeup. While it is becoming the new norm, the consequences of this behavior are emerging as a public health threat. Sedentary Behavior and Health will serve as a key reference for the rapidly emerging research area of sedentary behavior.

Shephard and published by Springer. This book was released on 2016-08-02 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the new knowledge that has been gained from the objective monitoring of habitual physical activity by means of pedometers and accelerometers. It reviews current advances in the technology of activity monitoring and details advantages of objective monitors relative to physical activity questionnaires. It points to continuing gaps in knowledge, and explores the potential for further advances in the design of objective monitoring devices. Epidemiologists have studied relationships between questionnaire assessments of habitual physical activity and various medical conditions for some seventy years. In general, they have observed positive associations between regular exercise and good health, but because of inherent limitations in the reliability and accuracy of physical activity questionnaires, optimal exercise recommendations for the prevention and treatment of disease have remained unclear. Inexpensive pedometers and accelerometers now offer the epidemiologist the potential to collect relatively precisely graded and objective information on the volume, intensity and patterns of effort that people are undertaking, to relate this data to past and future health experience, and to establish dose/response relationships between physical activity and the various components of health. Such information is important both in assessing the causal nature of the observed associations and in establishing evidence-based recommendations concerning the minimal levels of daily physical activity needed to maintain good health.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: There is much evidence to suggest the negative impacts that sedentary behaviour (SB) can have on one's health. What is less known is the specific effects of individual SBs. There is evidence to suggest that screen based SBs are adversely associated with physical health and that non screen based SBs may have beneficial associations with health. Using data collected by the Comprehensive School of Health Research Group (CSHR) as part of the SHAPES - PEI project, students self-reported the amount of time they spent participating in the following five sedentary behaviours: watching/streaming TV/movies, playing computer/video games, talking on the phone, surfing the internet, and reading for fun. The objective of this thesis was to estimate the impact of reallocating one sedentary behaviour with another on ten health outcomes: moderate-to-vigorous physical activity (MVPA), strength training frequency, flexibility training frequency, body mass index (BMI), perception of being overweight or underweight, fruit and vegetable consumption, salt and sugary snack consumption (SSS), sugar sweetened beverage consumption(SSB), and fast food frequency using an Isotemporal Substitution Method (ISM). Data for this questionnaire were collected during the 2014/2015 academic year. A total of 5621 children and youth (49% males) in grades 5 - 12 across Prince Edward Island (PEI) completed the questionnaire. Six of the above health outcomes did not meet the assumption of linearity for the ISM and as a result were dropped from future analysis. Results from the ISM indicated that replacing TV, computer/video games, internet, and reading for fun with talking on the phone was consistently associated with decreased likelihood of being physically inactive. Replacing screen based SBs, talking on the phone, and reading for fun resulted in similar reductions in the likelihood of not meting strength training guidelines. Replacing TV and computer/video games with internet, talking on the phone, and reading resulted in a decrease in the likelihood of living with overweight/obesity with the detrimental association of TV watching being significantly driven by females. Computer/video game had the most detrimental association on perceiving oneself as underweight when replacing all other SBs; significant findings were driven by female participants exclusively. Internet had the most detrimental impact on perceiving oneself as overweight when replacing all other SBs. When examining sexes separately, TV use had a detrimental associated with perceiving oneself as overweight for females, but not for males. Computer/video game use had a detrimental associated with perceiving oneself as overweight for males, but not females. Our results suggest that replacing screen-based SBs with non-screen-based SBs have a neutral or beneficial association with physical activity and weight status. These findings also highlight that the impact of SB varies depending on the specific behaviour being performed and across sexes. Future research should 1) examine the impact of multiple types of non-screen based SB and screen based SB on different lifestyle behaviours; 2) look at the specific content being viewed when performing these activities (i.e. educational or leisure); and 3) look at the determinants of SB on males and females separately.

Book excerpt: In recent years, diet- and lifestyle-related disorders have become a major health threat in Europe and worldwide. The contributions in this monograph include 2 review articles and 19 original contributions from several countries that provide new information on the existing research elucidating important aspects of children’s and adolescents’ nutrition and lifestyle behavior. The data included in this Special Issue are from large epidemiological studies, including several multicenter and multinational studies, as well as datasets from surveillance initiatives. The topics of interest of this Special Issue include the co-occurrence of multiple health behaviors in children, the role of parenting and early feeding practices, dairy consumption in childhood, validity of dietary intake data, dietary supplement use in children, as well as socioeconomic disparities and eating culture. The diverse articles in this Special Issue highlight the complexity and extent to which nutrition and physical activity behaviors may influence different health aspects of children and adolescents. As seen by the various findings and recommendations, not only is more work in this area required but the translation of this work to practice and policy is imperative if we are to address the challenges impacting the nutrition, physical activity, and health of young populations.

This book was released on 2020 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rationale: Sedentary behavior is characterized by too much sitting. It is estimated that 4 out of every 10 Americans never engage in physically active behaviors, and that approximately 60% of an adult's non-sleeping hours are spent in sedentary behaviors. As sedentary behavior increases, so do diagnoses of chronic illnesses such as diabetes, hypertension, cardiovascular disease, and kidney disease. Older adults are particularly at risk for sedentary behavior and the related chronic illnesses due to the challenges they face with balancing physical and/or cognitive limitations, medical conditions, and the requirements to remain physically active. Often times older adults feel that their only option for safe physical activity is low-speed walking. Occupational therapy intervention options that can decrease sedentary behavior in older adults in the community are scarce, thus the Everyday Meaningful Activities (EMA) intervention is proposed. The EMA Intervention combines concepts from Habit Formation Theory and the Ecology of Human Performance model. It is an individualized, client-centered intervention that aims to increase adherence to meaningful active lifestyle behaviors in older adults' lives. Meaningful active lifestyle behaviors are tasks or activities that promote enjoyment in time spent moving around (i.e. cooking, gardening, creating art, etc.). Participants created new habits by attaching these new active lifestyle behaviors to currently existing daily routines. The aims of this study are (1) to investigate the feasibility of implementing the EMA intervention with medically stable older adults, (2) to investigate the effectiveness of the EMA intervention in forming new active lifestyle behavior habits, and (3) to investigate the effectiveness of the EMA intervention in decreasing sedentary time. Method: Twelve medically stable older adults in the Greenville, NC community were recruited for this pretest/posttest, experimental design study. During six intervention sessions over six weeks, participants selected two new active lifestyle behaviors to make habitual and created action plans for implementation. Results: The recruitment rate for this study was 18%. The Rapid Assessment Disuse Index (RADI) was found to not be an appropriate measure for sedentary behavior for this population. The Short Blessed Test (SBT) was found to be an appropriate measure for screening cognitive impairment over the phone. Video conferencing was found to be an appropriate delivery method for selected intervention sessions if the participant is comfortable. Participants' subjective report of activity performance times is not a reliable subjective data collection method. The EMA intervention was effective in forming new active lifestyle behavior habits according to the Self- Report Habit Index (SRHI) and in decreasing perceived sedentary time spent according to the Sedentary Behavior Questionnaire (SBQ). Discussion: The EMA intervention is a viable intervention for decreasing sedentary behavior in medically stable older adults. With minor changes to the assessments used for screening, a wellrounded sample of participants can be created for pilot testing. In future applications of the EMA intervention, more reliable subjective data on activity performance should be collected in order to compare subjective and objective reports of activity performance.

Available in PDF, EPUB and Kindle. Book excerpt: The authoritative contributions gathered in this volume reflect the state of the art in compositional data analysis (CoDa). The respective chapters cover all aspects of CoDa, ranging from mathematical theory, statistical methods and techniques to its broad range of applications in geochemistry, the life sciences and other disciplines. The selected and peer-reviewed papers were originally presented at the 6th International Workshop on Compositional Data Analysis, CoDaWork 2015, held in L’Escala (Girona), Spain. Compositional data is defined as vectors of positive components and constant sum, and, more generally, all those vectors representing parts of a whole which only carry relative information. Examples of compositional data can be found in many different fields such as geology, chemistry, economics, medicine, ecology and sociology. As most of the classical statistical techniques are incoherent on compositions, in the 1980s John Aitchison proposed the log-ratio approach to CoDa. This became the foundation of modern CoDa, which is now based on a specific geometric structure for the simplex, an appropriate representation of the sample space of compositional data. The International Workshops on Compositional Data Analysis offer a vital discussion forum for researchers and practitioners concerned with the statistical treatment and modelling of compositional data or other constrained data sets and the interpretation of models and their applications. The goal of the workshops is to summarize and share recent developments, and to identify important lines of future research.
