Available in PDF, EPUB and Kindle. Book excerpt: BACKGROUND: Adolescence is a critical period for the study of physical activity as significant declines are often reported throughout the adolescent years. The reduction in physical activity is of great concern, due to its strong association with increasing levels of obesity among today's youth. Understanding the trajectory of change in physical activity and the influences of change has potential for informing future interventions and policy. PURPOSE: The purpose of this research was to examine trajectories of physical activity across adolescence and then compare correlates derived from Sallis' framework (demographics, self-efficacy, screen time and peer support). The correlates were examined as baseline predictors as well as potential dynamic factors, examining how change in influential factors may be simultaneously associated with changes in physical activity. METHODS: The data are derived from a school-based behavioral intervention trial involving an ethnically diverse sample of 1543 seventh graders from three urban schools in the Midwest. Latent trajectory models were used to model individual developmental change in physical activity, as well as dynamic correlates across adolescence. These models were then combined to compare the changes in correlates with the changes in physical activity. RESULTS: While the change in the group mean for physical activity was small, the latent trajectory analyses revealed significant individual change over time. Age, gender and race were each found to be associated with these trajectories. All hypothesized dynamic correlates (i.e., self-efficacy, screen time) were also found to change across time; however, only the trajectories of self-efficacy and peer support were simultaneously associated with changes in physical activity. CONCLUSIONS: The unique and dynamic changes in both physical activity and its correlates in adolescence underscore the importance of studying them longitudinally. Further, latent trajectory analyses produce richer results than group level analyses due to studying the individual differences. Children who establish patterns of high physical activity are more likely to retain these patterns through adolescence. However, developmental changes in perceived efficacy and peer behavior clearly play a strong role as well. This study can inform both family and school practices by establishing regular opportunities for physical activity in the years leading up to adolescence.

Available in PDF, EPUB and Kindle. Book excerpt: As interest in the public health challenge of youth inactivity increases, the ambitious Youth Physical Activity and Sedentary Behavior sets a standard for addressing a problem with worldwide implications. Drawing on the contributions of a diverse group of international experts, this reference challenges professionals, researchers, and students to implement new solutions and further their research and work. No other text addresses the causes, contributing factors, and fundamental issues in dealing with youth physical activity with such depth or comprehensive coverage. Using a multidisciplinary approach, Youth Physical Activity and Sedentary Behavior breaks away from traditional thinking that places activity and sedentary behavior on a single continuum, which may limit progress in addressing youth inactivity. Instead, the authors encourage readers to focus on how sedentary and physically active behaviors coexist and consider how the two behaviors may have different determinants. In doing so, the text also considers developmental features such as maturation, ethnicity, environment, and genetics across both childhood (through age 12) and adolescence (the teen years). By looking at a variety of psychosocial and epidemiological factors, the authors set the stage for a critical analysis of beliefs and views at a time when many assumptions are taken for granted. This book is organized in three parts that build on one another to deepen readers’ understanding of this complex problem. This text begins by addressing the fundamental issues and assumptions pertaining to youth physical activity and sedentary behavior, covering such topics as measurement of the behavior in question, health outcomes, concepts, and trends in a public health context. Once readers have grasped this foundational knowledge, they advance to part II for a comprehensive account of personal factors likely to be associated with the problem. Part III moves beyond the individual into the wider social and contextual aspects of physically active and sedentary living in young people. Through this concluding part, readers gain the latest thinking on how parents, peers, schools, organized sport, and related factors link to youth physical activity and sedentary behavior. Each chapter presents the latest theory and research, real-world approaches to implementation, and background information to encourage discussion and future directions in national policy making. Youth Physical Activity and Sedentary Behavior also contains the following features that add to an unprecedented learning experience: •An at-a-glance look at why and how research can be used in the real world helps researchers relate their work to overall solutions. •Coverage of more issues related to this subject than are available in any other reference makes this a one-stop resource. •Internationally respected foreword writer, editors, and contributors provide a cross-disciplinary perspective valuable for putting solutions into a wider context. •Applications for Professionals boxes and Applications for Researchers boxes at the end of each chapter provide practical suggestions for implementing solutions. Youth Physical Activity and Sedentary Behavior: Challenges and Solutions considers current research about youth physical activity and sedentary behavior across a range of personal factors as well as cultural and social influences. The text communicates the knowledge base on developmental, economic, psychological, and social factors related to youth physical activity and sedentary behavior and provides an overview of youth-specific approaches to addressing the problem of inactivity among youth.

This book was released on 2013-11-13 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical inactivity is a key determinant of health across the lifespan. A lack of activity increases the risk of heart disease, colon and breast cancer, diabetes mellitus, hypertension, osteoporosis, anxiety and depression and others diseases. Emerging literature has suggested that in terms of mortality, the global population health burden of physical inactivity approaches that of cigarette smoking. The prevalence and substantial disease risk associated with physical inactivity has been described as a pandemic. The prevalence, health impact, and evidence of changeability all have resulted in calls for action to increase physical activity across the lifespan. In response to the need to find ways to make physical activity a health priority for youth, the Institute of Medicine's Committee on Physical Activity and Physical Education in the School Environment was formed. Its purpose was to review the current status of physical activity and physical education in the school environment, including before, during, and after school, and examine the influences of physical activity and physical education on the short and long term physical, cognitive and brain, and psychosocial health and development of children and adolescents. Educating the Student Body makes recommendations about approaches for strengthening and improving programs and policies for physical activity and physical education in the school environment. This report lays out a set of guiding principles to guide its work on these tasks. These included: recognizing the benefits of instilling life-long physical activity habits in children; the value of using systems thinking in improving physical activity and physical education in the school environment; the recognition of current disparities in opportunities and the need to achieve equity in physical activity and physical education; the importance of considering all types of school environments; the need to take into consideration the diversity of students as recommendations are developed. This report will be of interest to local and national policymakers, school officials, teachers, and the education community, researchers, professional organizations, and parents interested in physical activity, physical education, and health for school-aged children and adolescents.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental correlates of physical activity behaviour have received much attention in the public health, geography, urban design, planning and transport literature over the past decade. Adolescents are an important age group to consider, given habits developed in childhood can potentially track into adulthood. This is an age where young people begin to have independent mobility, which has been associated with increased physical activity levels. The built environment is consistently associated with physical activity behaviours among adolescents. However, gaps in knowledge exist around which environmental features influence adolescent physical activity. Moreover, very little research has been undertaken on adolescents living in regional or rural areas.To date, proximity to parks (often measured as the closest park to a study participant's residence) and availability of facilities have often been examined as correlates of physical activity participation. Park attributes, that make parks more desirable to adults, have been identified and an attractiveness score has been developed in accordance with adult park use. Yet, there appears to be no published research that has identified which attributes of a park (in isolation or combination) make a park more appealing for adolescents to use for physical activity. Moreover, rarely has a study looked at the attributes of parks that have actually been reported as being used by study participants.Methods used to audit parks have traditionally relied on site visits to subjectively measure park attributes. This method of park auditing can be costly and time consuming. As such, a more objective method that eliminates the need for site visits could potentially advance research methods associated with the built environment and physical activity participation. Indeed, the use of geographic information systems (GIS) enables remote-assessment methods and the opportunity to measure park attributes in a more objective fashion.The overarching aims of this research were to investigate the environmental factors related to adolescent 'park and beach use' and physical activity and in doing so, develop environmental measures relevant to adolescent physical activity.

Available in PDF, EPUB and Kindle. Book excerpt: Current research shows that adolescents are not engaging in enough physical activity which has led researchers to explore factors that can lead to an increase in participation. When psychosocial factors have been researched in terms of adolescent physical activity participation, it has been found that parents play an important role. The more understudied factor is the role of peers in the determination of adolescent physical activity. The purpose of this study was to examine parental and peer influences on young adolescents' beliefs about and participation in physical activity. Three hundred fifty five 5 th and 6th grade student (n=191 males, n=164 females) ranging in age from 10 to 14 years (M age=11.8 yrs, SD=0.66) from the Rocky Mountain area participated in this study. Each participant completed a questionnaire which assessed importance and enjoyment of physical activity, social support, friendship quality, perceived competence, and physical activity levels. Children's ratings of enjoyment, importance, and competence of physical activity were significantly correlated with their perceptions of parental and peer ratings. The model of parental influence was not significant to predict MVPA but best friend influence was significant. The most importance factors contributing to influences were best friends' enjoyment and father's competence. The moderating variables (quality of relationship-parents and best friend) were not found to be significant. These findings suggest that more research needs to be done in order to determine the effect of parental and peer relationships on adolescents' physical activity levels.

Available in PDF, EPUB and Kindle. Book excerpt: Physical Activity Epidemiology, Second Edition, provides a comprehensive discussion of current population-level studies showing the influence of physical activity on disease. Updated with extensive new research collected in the eight years since the previous edition, the second edition adds the expertise of respected epidemiologist I-Min Lee. To assist readers in understanding the public health significance of physical activity, Dishman, Heath, and Lee present a detailed review of research findings and what those findings suggest regarding the relationship between physical activity and a variety of health risks. The second edition of this groundbreaking text has been exhaustively updated to reflect the wealth of new research published in this fast-moving field of study. With more than 100 pages of additional content, the text also offers more detailed coverage of all-cause and coronary heart disease mortality, expanded coverage of pathophysiology and biological plausibility, new information on physical activity among various racial–ethnic populations, and the effects of physical activity on cognitive function, dementia, and HIV/AIDS. More than 250 tables and figures, twice the number found in the previous edition, highlight the latest epidemiological information in an easy-to-understand visual format. Physical Activity Epidemiology, Second Edition, assists readers in understanding how leisure-time physical activity can enhance people’s quantity and quality of life by summarizing the available knowledge, detailing the methods used to obtain it, considering its implications for public health, and outlining the important questions that remain. Readers will find comprehensive discussion of these topics: • Evidence that physical activity protects against the development of coronary heart disease and stroke and premature death from all causes • Population-based studies and clinical experiments providing evidence that physical activity and exercise play a role in the primary and secondary prevention of mild hypertension, dyslipidemia, and obesity • Contemporary epidemiologic evidence that physical activity reduces the risk of type 2 diabetes and osteoporosis and protects against the development of breast and colon cancers, some inflammatory diseases, depression, and anxiety disorders • Considerations in the promotion of a safe, physically active lifestyle among all segments of the population Physical Activity Epidemiology, Second Edition, will engage and challenge students by examining the state of current research in all of its variation and even ambiguity. The text details the methodology and findings of classic and contemporary studies and then helps students begin to analyze the results. Special Strength of the Evidence sections found at the end of most chapters summarize the findings to determine the extent to which correlation and causation can be proven. Chapter objectives, chapter summaries, and sidebars in each chapter assist students in focusing on the key points of study, and an extensive glossary with detailed definitions provides a handy reference for review. Instructors will find a new image bank in this edition to enhance their class lecture materials. Physical Activity Epidemiology, Second Edition, offers students, sport and exercise scientists, health and fitness professionals, and public health administrators a comprehensive presentation of significant studies, how these studies contribute to understanding the relationship between activity and disease prevention, and how this information can be used in leading individuals, communities, and global society toward increased health and longevity.

Download or read book Relationships Among Physical Activity Diet and Obesity Measures During Adolescence written by Janne Holmberg Maier and published by . This book was released on 2014 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today's high prevalence of obesity is a concern especially in youth. Physical activity and diet are both important factors associated with weight management, and current recommendations are to consume a diet low in saturated fat and high in fiber, fruit and vegetables and to participate in frequent and regular physical activity. Adherence to recommendations is low, a factor that is strongly correlated with development of obesity and associated chronic diseases such as hypertension and cardiovascular disease. While associations between diet and physical activity are well established, investigation of changes in their association during growth is lacking. This thesis uses five years of diet, physical activity, and anthropometric data from 2379 adolescent girls in the National Heart Lung and Blood Institutes, Growth and Health Study to explore associations among diet, physical activity, and obesity cross-sectionally and with age. Variables representing physical activity, diet quality, and obesity, as well as income, maturation stage, and other potential confounders, were evaluated pair-wise for correlation, and bivariate statistics were examined for longitudinal trends. For further evaluation of relationships between groups of variables we used a canonical correlation analysis. First, physical activity variables were grouped with confounders and examined in relationship to diet quality variables; next, we grouped physical activity, diet quality, and confounders and examined the relationship to obesity measures. We found a moderately increasing correlation between physical activity and diet with age and an age-related decrease in correlation of all health behaviors and confounding variables with obesity measures, indicating that obesity measures become less sensitive to behaviors and socioeconomic factors with age at the same time as health behaviors become more tightly linked. These results suggest that while health behaviors continue to interact during growth, and in fact become more intertwined, measures of obesity become more static and may be less responsive to potential interventions with increasing age. These findings should motivate intervention work to aim for youth as potential impact would be greater before health behaviors and obesity measures become "locked in" to the more static frame of adulthood.
