Tailoring Digital Physical Activity Support Messages For Women In Midlife With Elevated Risk For Cardiovascular Disease: A Multicomponent Study, Kiri Baga

Theses and Dissertations

Women in midlife (ages 40-60) are at heightened risk for cardiovascular disease (CVD). Although physical activity (PA) engagement can reduce CVD risk, few women engage in sufficient PA to receive this benefit. They cite lack of social support as a key barrier, but existing interventions that employ social support show limited effectiveness. Digital PA support messages (i.e., brief, text-based messages delivered via smartphone or other device) may be a powerful method to meet social support needs in daily life. However, women’s preferences for and responses to distinct types of messages are not well understood. The aim of this study was …

Effectiveness Of Intervention Studies Based On Diet And/Or Physical Activity In Treatment, Prevention, And Management Of Diabetes Among South Asians: A Systematic Review, Ishaan Arora

Theses and Dissertations

The purpose of this study was to describe diet and/or physical activity-based interventions and their control in cardiometabolic risk factors of diabetes for the South Asian (SA) population. A systematic review was conducted in accordance with the PRISMA guidelines. Seventeen randomized control trials meeting the inclusion criteria were included for analysis. Interventions with type-2 diabetic SA showed significant improvements in HbA1c% (4/5 studies), fasting blood glucose (3/4 studies), and postprandial glucose (2/2 studies). Interventions with at-risk/prediabetic and non-diabetic SA showed a modest change in overall outcomes, with significant change reported for post-prandial insulin (3/4 studies), BMI and weight (2/4 studies), …

Greenspace Across The United States: Exploring Equity And Associations With Physical Activity, Obesity, And Health-Related Quality Of Life, Ellen W. Stowe

Theses and Dissertations

Neighborhood greenspace is important for health and well-being but may not be equitably present in neighborhoods across the United States. Also, many adults are physically inactive, have obesity, and report poor health-related quality of life. Greenspace has been tied to these health conditions, but with mixed findings. The purpose of this study was to 1) use an environmental justice perspective to examine variations in 11 measures of greenspace by neighborhood race/ethnicity, income, and rurality in block groups across the contiguous United States and 2) examine 11 greenspace measures in connection to physical activity, obesity, and health-related quality of life in …

Wearable Activity Trackers For Women: Motivating Factors For Increasing Physical Activity, Danielle A. Bate

Theses and Dissertations

Half of American women do not sustain recommended levels of physical activity (PA). Wearable activity trackers (WATs) may increase both awareness of, and PA if worn daily. Thus, WATs should include features and designs that encourage daily use. This study aimed to determine WAT features and designs most appealing to women and the motivational effects of various WATs. For this mixed-method pilot study, 15 women each trialed three WATs; documented daily PA levels; and rated their satisfaction with each device's comfort, features, and motivational effect. Additionally, participants shared experiences and feedback in focus groups. Features that promote adoption of WATs …

Sleep Self-Efficacy, Loneliness, And Physical Activity: Assessing The Pathways Between Sleep Quality And Mental Health Using Structural Equation Modeling, Amber M. Fox

Theses and Dissertations

Although there is robust empirical support that poor sleep contributes to declines in mental health, explanations of this relationship remain unclear. The purpose of the present study was to examine the pattern of associations between sleep quality, sleep self-efficacy, loneliness, physical activity, and mental health among U.S. adults across the lifespan, and whether they differed by gender or age group. A structural equation model with invariance analysis was developed and examined data from 2,300 adults (M_age = 44.1, SD = 16.78) participating in the online study Investigating Sleep Longitudinally Across Normal Development (ISLAND). Sleep quality was measured by …

Household Food Security, Lifestyle Factors, And Glycemic Control Among Youth And Young Adults With Diabetes, Lauren A. Reid

Theses and Dissertations

The purpose of this study was to assess the associations between household food insecurity (HFI) and glycemic control, physical activity, and diet quality in youth and young adults (YYA) with type 1 diabetes (T1D) and type 2 diabetes (T2D). Among older adults, HFI has been shown to complicate diabetes management due to the essential role of diet in diabetes management and the financial stress associated with HFI. Although HFI is more prevalent among YYA with diabetes than the general population, there are only a handful of studies that have focused on this population and, studies that include YYA with T2D …

Relationship Between Cognitive Performance, Physical Activity, And Socio-Demographic/ Individual Characteristics Among Aging Americans, Imtiaz Masfique Dowllah

Theses and Dissertations

Despite the attenuation of association following adjustments for covariates, participants who engaged in 3–6 hr/wk of vigorous- and > 1 hr/wk of moderate-intensity PA scored significantly higher in tests that assessed executive function and processing speed domains of cognition compared to inactive peers (η2 = 0.005 & 0.007 respectively, p < 0.05). Also, after adjustment, the effects of 1–3 hr/wk of vigorous-intensity PA became trivial for the delayed recall memory domain test scores (β = 0.33; 95% CI: –0.01, 0.67; η2 = 0.002; p = 0.56). There was no clear dose-response relationship between the cognitive test scores and weekly moderate-intensity PA. Interestingly, higher handgrip strength and higher late-life body-mass-index were associated with a higher performance across all cognitive domains. Observed associations provide evidence linking habitual PA with superior cognition health among older adults. Furthermore, increased muscle strength and higher late-life adiposity may …

Does Marriage, Employment And Having Children Matter? A Secondary Analysis On Physical Activity Levels, Leisure Time Physical Activity, And Social Roles Among Women In The United States, Tramaine Paul Mcmullen

Theses and Dissertations

Background: Social roles, such as being married, employed, or having children, have been shown to have independent negative relationships with moderate to vigorous physical activity (MVPA) levels among women. Increasing the number of women with children that meets physical activity guidelines is critical to reduce chronic disease and early mortality in this population. However, few studies have examined the relationship between holding multiple social roles, MVPA, and leisure-time physical activity (LTPA) among women with children. The study had two aims: 1) to determine the relationship between objectively measured MVPA by social roles and 2) to examine the frequency of specific …

Physical Activity Motivational Factors Of Activity Trackers For Young Adults, Amy L. Dalton

Theses and Dissertations

Activity tracker devices present as a promising and affordable tool to help promote physical activity and active choices. Additionally, young adults present as an ideal age group to implement behavior change interventions. OBJECTIVE: To determine what features of activity tracker hardware and software are helpful in motivating active choices. METHODS: This cross-sectional study included 149 participants ranging in age from 18-29 years old who wore an ActiGraph GT3X+ accelerometer for one week. They then continued to wear the accelerometer in …

Aerobic Exercise Exposure Targeting Anxiety Sensitivity: Effects On Associated Health Behaviors In Young Adults, Autumn Lanoye

Theses and Dissertations

Anxiety sensitivity (AS) is associated with health behaviors such as low rates of physical activity, overeating, alcohol use, and poor sleep; however, interventions targeting AS via exercise-based interoceptive exposure have not assessed these as outcomes. In addition, previous studies are limited by brief follow-up periods. This study aimed to replicate previous aerobic exercise interoceptive exposures with an extended (6-week) follow-up and measurement of health behaviors.

Participants were 44 sedentary young adults with elevated AS randomized to intervention (6 20-minute sessions of moderate-intensity treadmill walking) or assessment-only control. Assessments took place at baseline, week 2 (post-treatment), week 4, and week 8 …

Factors Influencing Health Behaviors In Those At Risk For Developing Schizophrenia, Adriana C. Pennacchi

Theses and Dissertations

Significant health concerns are common among those with schizophrenia- spectrum disorders and are associated with an average lifespan reduction of 15-20 years compared to the general public (Saha, Chant, & McGrath, 2007). Although symptoms of the disorder can disrupt self-care and health behaviors, evidence also suggests that problematic health behaviors are present before the onset of the manifest disorder. One example includes nicotine use which is elevated in those with a family history of schizophrenia (Ferchiou et al., 2012) and in those who show subclinical signs of risk for schizophrenia (Esterberg, Jones, Compton, & Walker, 2007). Despite these findings, there …

Associations Between Physical Activity And Weight Status With Grade-School Performance, Taylor Panfil

Theses and Dissertations

Physical activity and weight control are predictive of childhood health, but more recent research suggests they may also be associated with academic success.

PURPOSE: To explore the relationships between physical activity, weight status, and academic performance in children.

METHODS: 614 third-to-fifth grade children (53.9% female, age 9.6 ± 0.9 years) from two Midwestern communities participated. Physical activity was assessed using a Digiwalker 200-SW pedometer worn for seven consecutive days. Teachers provided an estimate of general academic performance, and children were categorized into three performance groups (high, moderate, low). School behavior (attentiveness, staying on task, interruptive behavior) was assessed by the …

The Impact Of The Ohana Mana Challenge On Native Hawaiian And Pacific Islander Children, Kristin Kay Van Tassell

Theses and Dissertations

In this four-week, family-focused pilot intervention study, researchers studied the impact of culturally relevant nutrition and activity sessions on eleven children from eight Native Hawaiian and Pacific Islander (NHPI) families. Mixed methods were used in analysis. In their favorite meal drawings, children included more fruits and vegetables at week four than week one, which was consistent with their self-reported intake of healthy foods that were new to them. From week one to four, mean total scores increased on the nutrition and exercise knowledge exercise questionnaire and the physical activity self-efficacy tool; however, the mean total score decreased on healthy diet …

Food Insecurity And Physical Activity Among U.S. Populations, Quyen G. To

Theses and Dissertations

Objectives: Examine the association between food insecurity (FI) and physical activity (PA) in the U.S. population.

Methods: Accelerometry (PAM) and self-report PA (PAQ) data from NHANES 2003-2006 were used. Those aged less than six years or were older than 65 years, pregnant, with physical limitations, or with family income above 350% of the poverty line were excluded. FI was measured by the USDA Household Food Security Survey Module. Crude and adjusted odd ratios were calculated from logistic regression to identify the association between FI and adherence to the PA recommendation. Crude and adjusted coefficients were calculated from linear regression to …

Impact Of Physical Activity In The Prevention Of Colorectal Cancer, Sarah Ashley Barnes

Theses and Dissertations

This review evaluates the current understanding of research on the impact of physical activity in the prevention of colorectal cancer. Current biological mechanisms implicated in physical activity and colorectal cancer risk reduction are blood glucose regulation, insulin sensitivity, leptin and adiponectin profiles, inflammation as well as secreted protein acidic and rich in cysteine (SPARC), an exercise induced myokine. Recent literature indicates that 30-60 minutes of moderate to vigorous activity a day is effective against colorectal cancer development, and there is convincing evidence of aerobic exercise as differently beneficial in recruiting mechanisms identified as preventative against colorectal cancer. This article provides …
