Background: Smartphone diet tracking applications (apps) are increasing in popularity but may not adequately address the important concerns of proper intake and of diet quality. Two novel weight loss apps were designed based on the popular dietary frameworks: MyPlate and FoodLists. MyPlate, the dietary guidelines put forth by the U.S. government, encourages a balanced diet from five primary food groups, but does not specify intake limits. The Food Lists set upper intake limits on all food groups except vegetables, and these guidelines extend to include fats, sweets, and alcohol. Objective: The purpose of this randomized controlled trial was to determine …

Introduction: Less than half of U.S. adults meet the aerobic physical activity guidelines to exercise at least 150 minutes a week. An individual's decision to be physically active is influenced by their perceptions of physical activity. To address perceptions, interventions need to be implemented where adults spend one third of their day; the workplace. A number of physical activity interventions have been conducted and few have been successful at improving physical activity; therefore, there is a need to explore novel approaches to improve physical activity in the worksite. The purpose of this pilot study was to examine the impact of …

INTRODUCTION: Exercise performed at moderate to vigorous intensities has been shown to generate a post exercise hypotensive response. Whether this response is observed with very low exercise intensities is unclear. PURPOSE: To compare post physical activity ambulatory blood pressure (ABP) response to a single worksite walking day and a normal sedentary work day in pre-hypertensive adults. METHODS: Participants were 7 pre-hypertensive (127 + 8 mmHg / 83 + 8 mmHg) adults (3 male, 4 female, age = 42 + 12 yr) who participated in a randomized, cross-over study that included a control and a walking treatment.

Most studies that explored the health benefits of interrupting sitting time focused on using different modalities (i.e., comparing walking vs standing breaks)33,36,59. However, experimental studies that directly compare patterns of interrupting sitting time through standing only are needed to advance the field. This study aimed to (i) determine if there is a difference in glucose response between continuous sitting (CS) and two intermittent standing regimes (high frequency, low duration breaks (HFLD) and low frequency, high duration breaks (LFHD)) and (ii) to determine if there is a difference in glucose response between the two strategies (HFLD vs. LFHD).

Atrial fibrillation (AF) is the most common abnormal heart rhythm, affecting nearly 2% of the world’s population at a cost of $26 Billion in the United States annually, and incalculable costs worldwide. AF causes no symptoms for some people. However, others with AF experience uncomfortable symptoms including palpitations, breathlessness, dizziness, and fatigue. AF can severely diminish quality of life for both AF sufferers and their loved ones. Beyond uncomfortable symptoms, AF is also linked to congestive heart failure and stroke, both of which can cause premature death. Medications often fail to control AF, leading patients and healthcare providers to seek …

Clinical Decision Support (CDS) is primarily associated with alerts, reminders, order entry, rule-based invocation, diagnostic aids, and on-demand information retrieval. While valuable, these foci have been in production use for decades, and do not provide a broader, interoperable means of plugging structured clinical knowledge into live electronic health record (EHR) ecosystems for purposes of orchestrating the user experiences of patients and clinicians. To date, the gap between knowledge representation and user-facing EHR integration has been considered an “implementation concern” requiring unscalable manual human efforts and governance coordination.

Purpose: Exercise interventions often result in less than predicted weight loss or even weight gain in some individuals, with over half of the weight that is lost often being regained within one year. The current study hypothesized that one year following a 12-week supervised exercise intervention, women who continued to exercise regularly but initially gained weight would lose the weight gained, reverting back to baseline with no restoration of set-point, or continue to lose weight if weight was initially lost. Conversely, those who discontinued purposeful exercise at the conclusion of the study were expected to continue to gain or regain …

College students experience a considerable amount of stress. Unmanaged stress is associated with poor academic performance, health risk behaviors (i.e., inadequate sleep and physical activity, alcohol consumption, poor dietary behaviors), and poor mental health. Coping with stress has become a priority among universities. The most tested stress-related programs to date have been mindfulness-based and face-to-face. These programs demonstrated significant improvements in stress, mindfulness, and self-compassion among college students. However, they may be burdensome to students as studies report low attendance and low compliance due to class conflicts or not enough time. Few interventions have used more advanced technologies (i.e., mobile …

Dietary protein is known to increase postprandial thermogenesis more so than carbohydrates or fats, probably related to the fact that amino acids have no immediate form of storage in the body and can become toxic if not readily incorporated into body tissues or excreted. It is also well documented that subjects report greater satiety on high- versus low-protein diets and that subject compliance tends to be greater on high-protein diets, thus contributing to their popularity. What is not as well known is how a high-protein diet affects resting metabolic rate over time, and what is even less well known is …

Many individual-level behavioral interventions improve health and well-being. However, most interventions exhibit considerable heterogeneity in response. Put differently, what might be effective on average might not be effective for specific individuals. From an individual’s perspective, many healthy behaviors exist that seem to have a positive impact. However, few existing tools support people in identifying interventions that work for them, personally. One approach to support such personalization is via self-experimentation using single-case designs. ‘Hack Your Health’ is a tool that guides individuals through an 18-day self-experiment to test if an intervention they choose (e.g., meditation, gratitude journaling) improves their own psychological …

Understanding how adherence affects outcomes is crucial when developing and assigning interventions. However, interventions are often evaluated by conducting randomized experiments and estimating intent-to-treat effects, which ignore actual treatment received. Dose-response effects can supplement intent-to-treat effects when participants are offered the full dose but many only receive a partial dose due to nonadherence. Using these data, we can estimate the magnitude of the treatment effect at different levels of adherence, which serve as a proxy for different levels of treatment.

Skeletal muscle (SM) mitochondria generate the majority of adenosine triphosphate (ATP) in SM, and help regulate whole-body energy expenditure. Obesity is associated with alterations in SM mitochondria, which are unique with respect to their arrangement within cells; some mitochondria are located directly beneath the sarcolemma (i.e., subsarcolemmal (SS) mitochondria), while other are nested between the myofibrils (i.e., intermyofibrillar (IMF) mitochondria). Functional and proteome differences specific to SS versus IMF mitochondria in obese individuals may contribute to reduced capacity for muscle ATP production seen in obesity. The overall goals of this work were to (1) isolate functional muscle SS and IMF …

Development of effective therapeutic interventions for the treatment of mental health disorders has been a significant driving force in the search to understand the human brain. Current treatments for mental health disorders rely on modulating neurotransmitter systems such as norepinephrine (NE), serotonin (5-HT), dopamine (DA) and γ-aminobutyric acid (GABA) to achieve clinically relevant relief of symptoms. While many medications are available to the clinician that individually target these neural systems, treatment often results in patients reporting unwanted side effects or experiencing incomplete relief.

Having accurate measurements of sedentary behaviors is important to understand relationships between sedentary behaviors and health outcomes and to evaluate changes in interventions and health promotion programs designed to reduce sedentary behaviors. This dissertation included three projects that examined measurement properties of wearable monitors used to measure sedentary behaviors. Project one examined the validity of three monitors: the ActiGraph GT3X+, activPAL™, and SenseWear 2. None of the monitors were equivalent with the criterion measure of oxygen uptake to estimate the energy cost of sedentary and light-intensity activities. The ActivPAL™ had the best accuracy as compared with the other monitors. In …

ABSTRACT Millions of US aging individuals are at risk for mild cognitive impairment (MCI), the early stage of Alzheimer's disease (Ad). Ad is progressive; there is no clinical cure to date. Certain drugs treat symptoms yet fog memory. Memory activity is critical to strengthen cognition. The Phoenix Art Museum (PAM) and Banner Alzheimer's Institute (BAI) founded the Arts Engagement Program (AEP), a non-clinical, specialized arts program for adults with (MCI) and their caregiver. The museum environment is thought to enhance communication and raise self-esteem in certain MCI individuals. The interior surroundings may spurn memory enhancement. Scholarship to substantiate this theory …

Transfer learning is a sub-field of statistical modeling and machine learning. It refers to methods that integrate the knowledge of other domains (called source domains) and the data of the target domain in a mathematically rigorous and intelligent way, to develop a better model for the target domain than a model using the data of the target domain alone. While transfer learning is a promising approach in various application domains, my dissertation research focuses on the particular application in health care, including telemonitoring of Parkinson’s Disease (PD) and radiomics for glioblastoma.

ABSTRACT PHYSCIAL ACTIVITY AND EXECUTIVE FUNCTIONING IN COLLEGE STUDENTS INTRODUCTION: Regular physical activity may increase neurological development, which has been shown to increase cognitive functioning in older adults and those with dementia. Studies have also shown physical activity and exercise may positively affect executive functioning in children. Little is known about the influence of physical activity on executive functioning in college students between the ages of 18-21 years, a population that is traditionally thought of as healthy. Therefore, the purpose of this study is to explore the association between physical activity and executive functioning in college-aged students. We hypothesize that …

This study was designed to investigate whether workplace positivity of full-time workers was related to health ratings. Positivity was conceptualized by a high rating of perceived work-performance, and work-engagement as defined by the Utrecht Work-Engagement Scale, including vigor, dedication, and absorption (Schaufeli, & Bakker, 2004). Health was measured utilizing the RAND SF-36 health survey including the eight subscales: overall, general health, physical and social functioning, emotional well-being, role limitations due to physical health or emotional problems, energy or fatigue, and bodily pain. All measures were collected simultaneously. It was predicted that perceived work-performance and all measures of work-engagement are positively …

Exercise serves as a powerful stimulus to induce skeletal muscle adaptation. For instance, it is well understood that aerobic exercise (AE) elicits an adaptive response ultimately leading to increased fatigue resistance and capillarization, whereas resistance exercise (RE) is known to elicit an adaptive response leading to increased muscle strength and size. However, the precise molecular mechanisms mediating these unique adaptations to different forms of exercise remain to be completely resolved. The purpose of this study was to investigate the adaptive cellular response of skeletal muscle following acute AE and RE. Specifically, this study focused on two molecular processes: 1) mammalian/mechanistic …
