Message Framing And Physical Activity: One Size Fits All Versus A Tailored Approach, Konstantinos Mantis Jan 2017

Message Framing And Physical Activity: One Size Fits All Versus A Tailored Approach, Konstantinos Mantis

Graduate Theses and Dissertations

Message framing (i.e., emphasis on gains or losses) is a communication strategy that has been used to promote physical activity (PA). Previous research has led to inconsistent results regarding the persuasive effect of gains and losses. The purpose of this dissertation was to explore whether a fit between message content and individuals’ motivational orientation improves the effectiveness of messages. Undergraduate students participated in studies via the Department of Psychology SONA system. Study 1 (n = 441) tested whether a fit between Frame (gains, losses), Regulatory Focus (promoters, preventers), and Message Valence (positive, negative, mixed) improves the persuasiveness of PA messages ...


Sedentary Lifestyle And Obesity In Adults, Youngwon Kim Jan 2015

Sedentary Lifestyle And Obesity In Adults, Youngwon Kim

Graduate Theses and Dissertations

Excessive time spent on sedentary behavior (SB) can increase the risks of obesity, regardless of engagement in physical activity (PA). Subjective and objective measures are both available to assess SB but little is known about the relative utility of these measures for epidemiological research. The purposes of this dissertation were to 1) evaluate the accuracy of 24-hour Physical Activity Recall (24PAR) relative to SenseWear Armband (SWA) for assessing SB, 2) characterize the context of SB by demographic indicators, and 3) determine the independent/joint associations of SB and PA with obesity by the 24PAR versus SWA.

The first study demonstrated ...

Obesity and incidence of chronic disease continue to rise in the United States. The current medical paradigm focuses on treatment of chronic disease. A shift from the management of disease to prevention of obesity and its associated co-morbidities including diabetes mellitus and cardiovascular disease is necessary to protect the health of future generations. Pregnancy is a "teachable moment" offering a time when many women are motivated to make healthier lifestyle choices to optimize the health of their unborn child. This critical stage of the life cycle offers a unique opportunity to influence the health of future generations by modifying the ...


Childhood Obesity Prevention Intervention: Exploring Food Preferences And Physical Activity Self-Efficacy, Hannah Ostrander Jan 2014

Childhood Obesity Prevention Intervention: Exploring Food Preferences And Physical Activity Self-Efficacy, Hannah Ostrander

Graduate Theses and Dissertations

BACKGROUND: Overweight and obese children and adolescents are at greater risk for being overweight or obese as adults as well as developing one or more chronic diseases. Approximately one third (31.8%) of children in the Unites States are either overweight or obese (16.9% being obese). The causes of obesity are complex and multifactorial, an interaction between biological, psychological, and environmental factors. Physical activity and dietary habits are two major contributing modifiable factors in determining one's health and weight status. Interventions are needed to help curb the obesity epidemic by working toward improving the health status of children ...


Validity Of Consumer-Based Physical Activity Monitors And Calibration Of Smartphone For Prediction Of Physical Activity Energy Expenditure, Jung-Min Lee Jan 2013

Validity Of Consumer-Based Physical Activity Monitors And Calibration Of Smartphone For Prediction Of Physical Activity Energy Expenditure, Jung-Min Lee

Graduate Theses and Dissertations

Accelerometry-based activity monitors have become the standard objective method for assessing physical activity (PA) in field-based research [1]. They are small, non-invasive, easy-to use, and provide an objective indicator of physical activity over extended periods of time. The main advantage from a research perspective is they provide an objective indicator of physical activity behavior, thereby avoiding common sources of error in subjective measurement (e.g., self-report). Because of their storage data capacity, it is possible to monitor behavior over extended periods of time and easy to download the information to a computer for processing. Numerous studies have been published on ...


Promoting Older Adult Wellness Through An Intergenerational Physical Activity Exergaming Program, Kara Anne Strand Jan 2012

Promoting Older Adult Wellness Through An Intergenerational Physical Activity Exergaming Program, Kara Anne Strand

Graduate Theses and Dissertations

Background. The older adult population has been on the rise since the 1900s and is projected to increase to 72.1 million people by 2030 (Administration on Aging, 2011). Today's older adults suffer from chronic diseases that are preventable with regular physical activity. Although physical activity has been shown to prevent or improve chronic diseases as well as improve physical fitness, balance, strength, flexibility, and overall quality of life, fewer than five percent of older adults are meeting the current recommendation for physical activity. Additionally, rural-residing older adults are half as likely to participate in physical activity as urban-residing ...


Assessment Of Contributors To The Metabolic Syndrome Among Law Enforcement Officers, Hyelim Yoo Jan 2011

Assessment Of Contributors To The Metabolic Syndrome Among Law Enforcement Officers, Hyelim Yoo

Graduate Theses and Dissertations

The metabolic syndrome has received increased attention in the past few years. The metabolic syndrome is a cluster of cardiometabolic risk factors including central obesity, dyslipidemia, hypertension, and glucose intolerance. Due to higher prevalence of obesity, lack of physical activity, and high stress levels, law enforcement officers (LEOs) may be at high risk for the metabolic syndrome. However, the risk factors for the metabolic syndrome in this specific occupation have not been fully examined. The purpose of this dissertation was to assess the contributors to the metabolic syndrome among LEOs. This dissertation consists of a series of manuscripts which focus ...


Physical Activity Levels And Cardiovascular Disease Risk Among U.S. Adults: Comparison Between Self-Reported And Objectively Measured Physical Activity, Jared Tucker Jan 2010

Physical Activity Levels And Cardiovascular Disease Risk Among U.S. Adults: Comparison Between Self-Reported And Objectively Measured Physical Activity, Jared Tucker

Graduate Theses and Dissertations

Background: In 2008, the US Department of Health and Human Services released the first set of official US physical activity guidelines (Physical Activity Guidelines for Americans - PAGA). These guidelines are based on numerous studies that have linked self-reported PA to substantial health benefits. However, levels of PA among US adults remain relatively low, and differ substantially depending upon whether measured subjectively or objectively. Therefore, a better understanding between these measures is needed. Additional evidence linking objective PA to health outcomes is also needed. Furthermore, no study has examined the proportion of Americans achieving the PAGA using an objective measure. Purpose ...
