Understanding Adolescent Physical Activity In The Early Nutrition Transitioning Country Of Haiti, Haley V. Becker

Arts & Sciences Electronic Theses and Dissertations

The nutrition transition is underway in Haiti, giving rise to the dual burden of malnutrition. Physical activity (PA) plays an important role in mitigating the negative health consequences of nutrition transition and the dual burden, but heretofore this data has been unavailable for Haiti. This dissertation undertook an exploratory needs assessment providing baseline PA data for Haitian adolescents. It evaluated two different PA data collection methodologies: a cross-sectional survey adapted from the IPAQ long-form and objectively measured PA via Actigraph GT1M accelerometers. Next, it identified initial covariates of self-reported and objectively-assessed PA behaviors; data was operationalized as meeting the World …

Increasing Physical Activity To Improve Health Through Primary Care Clinics In Rural Nebraska, Jill Reed

Theses & Dissertations

Addressing the lack of physical activity (PA) in rural adults is vital because of the role it plays in the risk for many chronic diseases. The purpose of the study was to explore the feasibility of conducting a 12-week intervention to increase PA behavior in inactive rural adults recruited from a primary care clinic. Subjects were randomized to the intervention (n=30) or control (n=29) group and wore a Fitbit to track PA. The intervention group completed action plans and received weekly motivational text messages to improve PA behaviors. Semi-structured interviews were conducted with study participants (n=10) and a focus group …

Physical Activity During Pregnancy And Birth Outcomes In South Carolina 2009-2015, Andrew Tyler Broadway

Theses and Dissertations

Physical activity is known to be beneficial to adults in general, including pregnant women, but the literature on physical activity and neonatal outcomes has been inconsistent. Few studies have differentiated between physical activity prior to pregnancy and during pregnancy to see whether the typical beneficial effect is not due to having a more active lifestyle in general. The Pregnancy Risk Assessment Monitoring System (PRAMS) is a national cross-sectional surveillance system. Our data from SC PRAMS included 6391 respondents and was weighted to be representative of population of pregnant women that delivered in the state. We excluded births that were not …

Examining The Relationships Between School Engagement, Physical Activity, And Attention-Deficit Hyperactivity Disorder In Children Using The Ecological Model, Minh Nguyen

Theses & Dissertations

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder with onset usually occurring in childhood and adolescence. During these developmental stages, social interactions and external environments can have significant impact on children’s growth and development. Few studies previously used a theoretical model to examine the effects of social and external environments on ADHD. The goal of this dissertation is to apply an ecological perspective to examine the roles of school and community in the development of childhood ADHD through school engagement and physical activity. Three studies were implemented to carry out this goal. Study 1 examined the associations of neighborhood, school, and …

Active And Safe Routes To School: Evaluating School Travel Planning To Support Children's Active Travel, Adrian Nicholas Buttazzoni

Electronic Thesis and Dissertation Repository

Most Canadian children are not achieving their daily recommended physical activity (PA) levels despite the many emotional, psychological, and physical benefits of PA. Walking or wheeling to/from school, or active school travel (AST), is a viable method for improving children’s daily participation in PA. In Canada, the Active and Safe Routes to School initiative promotes AST through its comprehensive School Travel Planning (STP) program. Utilizing a mixed-methods approach, broadly, this thesis investigates the i) implementation and ii) effectiveness of a regional, two-year STP program supporting AST. This thesis includes a systematic review of AST intervention models implemented in North America, …

Examining Geographic Variation In Children's Perceived Barriers To Physical Activity And The Implications On Behaviour, Leah Gabrielle Taylor

Electronic Thesis and Dissertation Repository

Low levels of physical activity among Canadian children has become a national public health issue. Recent research has suggested that children’s physical activity levels are associated with their perceptions of their everyday environments. A better understanding of the formation of these perceptions within different contexts is needed to explain the extent of the relationship. Using a multi-tool quantitative protocol, this thesis examines geographic variation in socio-ecological factors influencing children’s perceptions of barriers to PA, and the extent to which perceptions mediate the relationship of the environment and PA. Results indicate that perceptions form within contexts, and have an influence on …

Exploring The Influence Of Childcare Type On Physical Activity And Sedentary Time Of A Nationally Representative Sample Of Canadian Preschoolers, Julie Statler

Electronic Thesis and Dissertation Repository

A large number of Canadian children are enrolled in childcare, and they spend substantial time there. Capturing a national picture of the relationship between childcare type and physical activity (PA; i.e., light, moderate- to-vigorous, and total) and sedentary time (ST) in young children is needed. Using a nationally representative sample of preschoolers (aged 3-5 years), this cross-sectional study used cycles 3 and 4 of the Canadian Health Measures Survey. Childcare type (e.g., centre-, home-based childcare, home with parent, kindergarten) was reported by parents. Preschoolers wore an accelerometer for 7 consecutive days. Device and population-specific cut-points were applied to delineate PA …

Exploring The Physical Activity And Screen Viewing-Related Knowledge, Training, And Self-Efficacy Of Early Childhood Education Candidates, Brianne Bruijns

Electronic Thesis and Dissertation Repository

Early childhood educators (ECEs) greatly influence young children’s physical activity (PA) and screen viewing (SV) behaviours. This study explored the PA and SV-related knowledge (i.e., of important PA/SV concepts), training (i.e., PA/SV courses/content received), and self-efficacy (i.e., to facilitate PA and limit SV in childcare) of early childhood education students. A sample of 1,292 students from 61 Canadian colleges/universities completed the online survey. In general, students exhibited the least amount of knowledge regarding the link between SV and health. Further, 67.8% and 73.3% of students had not completed PA or SV courses during their post-secondary training, respectively, and students who …

Temporal And Intensity Relationships Between Physical Activity And Drunkorexia Behaviors Among First-Year College Students, Robert E. Booker Jr

MSU Graduate Theses

The purpose of this research was to examine the temporal element of physical activity (PA) in relation to drunkorexia occurrences and how PA intensities predict severity of drunkorexia behaviors. No research, to our knowledge, has explored if students are proactively or reactively engaging in PA to reduce the effects of calories consumed from alcohol nor if there exists a dose relationship among PA intensities (sedentary, moderate, vigorous) and severity of drunkorexia behaviors. A convenience sample of first-year college students living in residence halls was selected to participate in the current study. Participants completed an online survey including The Drunkorexia Motives …

Perceptions’ On The Impact Of Families For Health After-School Program, Kathryn Lane

Health Sciences Student Work

Introduction Studies show that parents send their children to afterschool programs as a form of supervision while they are at work, but studies also stress the importance in the parental role in a child’s ability to retain the skills and concepts that are learning within these programs. So what if there was an afterschool program where parents attended and participated with the children, would this have an effect on the impact of the program? Families for Health is an afterschool program designed to bring Families together while teaching key concepts that lead to a healthy lifestyle, focusing on physical activity …

Physical Activity And Veteran Status In Obesity And Chronic Obstructive Pulmonary Disease, Erin Mcguire Kren

Walden Dissertations and Doctoral Studies

There are few data available regarding the relationship between physical activity and veteran status in those with combined chronic obstructive pulmonary disease (COPD) and obesity. COPD is a common illness and a leading cause of death in the United States. Veterans represent a distinct subpopulation in the United States and are more likely to have COPD, which is a disease with a high rate of comorbidities such as obesity. Physical activity can improve outcomes for those with COPD and obesity. However, recommendations for physical activity for those with COPD and obesity are vague. This study, based on the self-determination theory, …

Relationship Between Exposure To Phthalate And Obesity In The United States, Gladys Chidiebere Ezem

The Role Of Exercise For Postpartum Depression And Well-Being, Maria Gaz

All Graduate Theses, Dissertations, and Other Capstone Projects

Postpartum depression is a prevalent condition (American Psychological Association, 2018). Untreated postpartum depression can have serious consequences for the mother and baby (McCurdy, Boule, Sivak, & Davenport, 2017). Traditional treatment options may not be feasible. Exercise is an effective treatment for adults with depression (McCurdy et al., 2017). Less is known about treating postpartum depression with exercise. This review of the literature sought to understand in postpartum mothers, how a regimen of regular exercise, compared to no regular exercise, impacted the perception of wellbeing and/or postpartum depression scores. The Cumulative Index to Nursing and Allied Health Literature (CINAHL) Plus with …

Interleukin-6 And Exercise; Early Evidence Of A Novel Myokine, Brendan Hogg Mr.

Graduate Student Theses, Dissertations, & Professional Papers

Interleukin-6 (IL-6) was first identified as a pleiotropic cytokine, with a host of body-wide functions. Cytokine functions are characterized by chronically elevated levels within various inflammatory states. In this regard, IL-6 is largely associated with the acute phase response to many stimuli and performs specific actions when produced from certain cell types. Accrued evidence indicates IL-6 release from skeletal muscle often includes myokine functions. Novel myokine functions are adaptive in nature, and as compared to inflammatory/cytokine roles, exhibit a transient time course. Following exercise plasma IL-6 peaks and returns to resting levels within 1-2 hours. In contrast, IL-6 is observed …
