Exploring The Associations Between Sexism, Physical Behaviors, And Psychosocial Correlates Of Physical Activity In Young Women, Melanna Cox

Doctoral Dissertations

Physical behaviors (PB), defined as physical activity (PA) and sedentary behavior (SB), tend to be less favorable in women than in men. Low self-efficacy (SE) and social support (SS), and gender norms hinder women’s PB. Benevolent sexism, a theory on gender norms, could explain the gender disparity. PURPOSE: To 1) assess the associations among benevolent sexism endorsement (BSEN), experiences with benevolent sexism (EBS), PB, SE, and SS, 2) evaluate if BSEN or SE mediate the relationship between EBS and PB, and 3) develop a questionnaire that measures a woman’s sexist experiences in PA. METHODS: Study 1: Women (N=186) completed a …

Physical Activity, Daily Step Counts And Functional Ability In Older Adults: Using Nhanes Database, Chunfang(Maggie) Chen

Doctoral Dissertations

Maintaining functional ability and independence are essential in the healthcare of older adults. Physical activity(PA) has been acknowledged as effective and economical health promotion strategies in older population. However, the amount of PA needed to maintain functional ability in older adults remains unclear. This investigation used PRISM Dose-response Curves Stimulation Variable slope model to explore the relationships between the amount of PA and functional ability in community-dwelling young-old, middle-old and old-old age group adults. ANOVA analysis was used to examine the relationship between functional ability and self-perceived active level changes compared to 10 years ago. NHANES 2005-2006 older participants datasets …

The Impact Of A Lifestyle Intervention On Risk Factors Of Cardiovascular Disease And Type Ii Diabetes Among At-Risk Hispanic Women, Kathryn A. Wagner

Doctoral Dissertations

Cardiovascular disease and type 2 diabetes are global epidemics affecting approximately 127 and 21 million people in the U.S., respectively. Women who are overweight, obese or who develop glucose intolerance during pregnancy represent high-risk groups for the development of cardiovascular disease and type 2 diabetes. Hispanic women are both more likely to begin their pregnancies as overweight or obese and have a higher prevalence of type 2 diabetes, compared to non-Hispanic whites. However, prior lifestyle interventions have largely been limited to non-Hispanic whites. Therefore, this research assessed how culturally tailored lifestyle modification may affect cardiovascular disease and type 2 diabetes …

Assessment Of Physical Activity And Sedentary Behavior Using Wearable Sensors: Measurement Considerations And Clinical Applications, Amanda Hickey

Doctoral Dissertations

The aims of study one of this dissertation were two-fold: 1) To understand the variability of sedentary behavior (SB) throughout a seven-day measurement period and 2) To determine the number of days of SB measurement required to reliably estimate seven-days of measurement. To address these aims, we utilized activPAL (AP) data from two existing data sets from the Physical Activity (PA) and Health Laboratory. Data were from 62 adults and 34 adolescents who had seven consecutive days of valid monitor wear. We found that adults were more sedentary on weekdays compared to weekend days, but there were no differences by …

Feasibility Of A Combined Physical Activity And Sleep Education Intervention For Girls Living In A Low Socioeconomic Status Urban Community, Cory J. Greever

Doctoral Dissertations

Declining sleep duration and poor sleep quality is a public health epidemic disproportionately effecting elementary age girls living in low socioeconomic status urban communities. The Girls Dancing and Sleeping for Health (Girls DASH) program was designed to test the feasibility, acceptability, and efficacy of a combined physical activity and sleep education program in this population. In combination with baseline data from a previously conducted intervention in elementary age urban girls living in a low SES community in Springfield, MA, results from a cross-sectional analysis indicated that greater screen time was positively associated with parental reports of child’s sleep quality. Additionally, …

Impact Of A Preschool Workplace Intervention On Classroom Teachers’ Physical Activity Levels And Quality Of Life, Ogechi O. Nwaokelemeh

Doctoral Dissertations

PURPOSE: To examine the feasibility and efficacy of a three-month, cluster-randomized workplace PA intervention on PA levels and wellbeing measures in preschool classroom teachers. METHODS: Ten preschool centers were randomized into two groups; short-bouts of structured PA (SBS-PA, n=5) or traditional unstructured PA (TRAD-PA, n=5). The SBS-PA intervention consisted of 10-minute structured, teacher-led PA routines implemented within the classroom setting, followed by 20 minutes of unstructured playtime. The TRAD-PA intervention consisted of supervised 30-minute of unstructured free playtime. Both interventions were implemented during the morning and afternoon designated gross-motor playtime for 30 min/session, five days/week for three months. Participants’ …

The Evaluation Of Select Lifestyle Behavior Modification Following Participation In A Comprehensive Weight Management Clinic, Jennifer L. Bowling

Doctoral Dissertations

Over the last decades, obesity in the United States has reached epidemic proportion. Obesity rates have nearly doubled since 1960 when 43% of the United States population was overweight or obese and 1% was extremely obese. In 2012, approximately 69% of the US population was overweight or obese while 6.3% were extremely obese. Obesity rates are expected to progressively increase; therefore, interventions and guidelines are imperative in order to reduce the long term health risks of the Nation and to reduce overall health care costs (National Institute of Health [NIH], 2012).

Obesity increases morbidity resulting from associated hypertension, cardiovascular disease, …

Primary Care Assessment And Interventions To Improve Physical Activity Among Insufficiently Active Adults Ages 18 Through 64 Years Old, Thomas A. Sanchez

Doctoral Dissertations

A number of chronic and debilitating conditions such as cardiovascular disease, stroke, hypertension, anxiety, depression, pain, osteoporosis, and falls are known to be delayed, improved, or prevented by increasing physical activity (PA) levels. The numbers of those affected form a substantial portion of the US population. As of 2011, for example, 26 million adults in the U.S. were diagnosed with diabetes mellitus (DM) alone. Another 79 million people had elevated blood glucose measurements putting them at risk for DM. Despite knowledge of the connection with chronic disease, PA levels are not consistently and quantitatively assessed during primary care office visits. …

Stress And Depression During Pregnancy Among Hispanic Women: Risk For Adverse Birth Outcomes And The Role Of Physical Activity, Kathleen Szegda

Doctoral Dissertations

Preterm birth and low birth weight are among the leading causes of infant mortality and morbidity in the United States. Puerto Rican women are at increased risk for these adverse birth outcomes and elevated levels of depression and psychosocial stress during pregnancy when compared to non-Hispanic Whites. Therefore, it is important to understand whether these psychological factors increase risk for these adverse birth outcomes and mechanisms to prevent/reduce depression in this high-risk population. The first study of this dissertation examined associations between perceived stress during pregnancy and preterm birth, low birth weight, and birth of a small-for-gestational age infant (SGA) …

The Estimation Of Caloric Expenditure Using Three Triaxial Accelerometers, Tyrone Gene Ceaser

Doctoral Dissertations

Accelerometer-based activity monitors are commonly used to measure physical activity energy expenditure (PAEE). Newly designed wrist and hip-worn triaxial accelerometers claim to accurately predict PAEE across a range of activities. Purpose: To determine if the Nike FuelBand (NFB), Fitbit (FB) and ActiGraph GT3X+ (AG) estimate PAEE in various activities. Methods: 21 healthy, college-aged adults wore a NFB on the right wrist, a FB on the left hip, and AG on the right hip, while performing 17 activities. AG data were analyzed using Freedson’s kcal regression equation. PAEE was measured using the Cosmed K4b² (K4). Repeated measures ANOVAs were used …
