Obesity Prevention Toolkit To Combat Weight Gain Related To Sedentary Behavior And Dietary Habits In College Students: An Evidence-Based Project, Maria Amos, Martha Fuller

Doctor of Nursing Practice Final Manuscripts

Abstract

Background: Forty percent of the US population ages 20-39 are categorized as obese,

their BMI is over 30, and 35% of college age students are obese or overweight. Issues related to obesity cost the US $147 billion annually. Between 40%-50% of college students are reported to be inactive. Inactivity can lead to increased morbidity and mortality related to increased risks of cardiovascular disease, diabetes, hypertension, musculoskeletal issues, and depression. Providing dietary and physical activity education and access to nutritional information promotes behavior change in young adults.

Aims of Service Change: This evidence-based project proposal aims to provide a toolkit …

Differences In Running Mechanics And Tibial Plateau Dimensions Between Overweight/Obese And Healthy Weight Children, Claire Sylvestre

Electronic Theses and Dissertations

INTRODUCTION: Overweight and obese (OW/OB) children display increased knee joint loading during running, which may lead to excessive frontal plane motion and moments at the knee joints. The relationship between tibial plateau dimensions and knee vertical loading may explain the loading related injuries OW/OB children experience.
PURPOSE: Compare knee mechanics during running and tibial plateau dimensions between healthy weight (HW) and OW/OB children.
METHODS: Ten HW children and ten OW/OB children aged 9-12 participated in the study. Kinematic and kinetic data were captured as participants ran across a force platform at 3.5m/s. Tibial plateau area and density were collected by …

Differences In Physical Activity And Diet Patterns Between Non-Rural And Rural Adults., Lacey Mccormack, Howard Wey, Jessica R. Meendering, Bonny Specker

Health and Nutritional Sciences Faculty Publications

BACKGROUND: It is unclear how rural occupations and lifestyles may play a role in shaping physical activity and diet behaviors that contribute to the rural⁻urban obesity disparity.
METHODS: Data come from the prospective and observational South Dakota Rural Bone Health Study, which included adults aged 20⁻66 years in three groups: (1) non-rural non-Hutterite, (2) rural non-Hutterite, and (3) rural Hutterite. Physical activity data were collected using 7-day physical activity questionnaires, and hours per day in physical activity categories are reported. Diet data were collected using food frequency questionnaires, and food group servings per day (svg/day) are reported. Mixed models were …

The Effects Of An Acute Bout Of Exercise On Hunger Hormones In Individuals At Risk For Type 2 Diabetes, Sydney Spoon

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: Hunger hormone levels are typically dysregulated in obese and diabetic

populations, however; postprandial exercise has been shown to influence hunger hormone levels. Purpose: To determine if hunger hormones including acylated ghrelin and GLP-1 levels are altered in response to an acute bout (15 minutes) of walking in individuals at risk for type 2 diabetes mellitus (T2DM).

Methods: Ten subjects at risk for prediabetes (fasting blood glucose 100–125mg/dL) participated in this randomized crossover design trial. Subjects arrived at the laboratory following an overnight fast and underwent one of two conditions: 1) Test meal with no walking (CON) or 2) Test …

Household, Psychosocial, And Individual-Level Factors Associated With Fruit, Vegetable, And Fiber Intake Among Low-Income Urban African American Youth., Angela Cristina Bizzotto Trude, Anna Yevgenyevna Kharmats, Kristen Marie Hurley, Elizabeth Anderson Steeves, Sameera A Talegawkar, Joel Gittelsohn

Exercise and Nutrition Sciences Faculty Publications

BACKGROUND: Childhood obesity, one of the greatest challenges to public health, disproportionately affects low-income urban minority populations. Fruits and vegetables (FV) are nutrient dense foods that may be inversely associated with excessive weight gain. We aimed to identify the individual characteristic, psychosocial, and household factors influencing FV and fiber consumption in low-income African-American (AA) youth in Baltimore, MD.

METHODS: Cross-sectional analysis of data collected from 285 low-income AA caregiver-youth (age range: 10-14 y) dyads participating in the baseline evaluation of the B'More Healthy Communities for Kids obesity prevention trial. The Kid's Block FFQ was used to estimate daily intakes of …

Autophagy Regulation After Diet And Exercise In Non-Alcoholic Fatty Liver Disease, Megan Elizabeth Rosa

Graduate Theses and Dissertations

Along with the rise in obesity, rates of non-alcoholic fatty liver disease (NAFLD) have also increased. NAFLD may begin with fat accumulation in the liver, but can progress to non-alcoholic steatohepatitis (NASH), fibrosis, and eventual cirrhosis. With no pharmacological treatment for NASH, lifestyle interventions appear vital to maintaining liver health. Previous work has shown aberrant mitochondrial content/quality and autophagy in models of NAFLD. Exercise is known to improve mitochondrial health and possibly autophagy, thus autophagy may be a key regulatory factor for treatment of obesity induced-NAFLD. PURPOSE: The purpose of the study was to examine how weight loss from diet …

Workforce Fitness: Description, Contextual Issues, And Implications For Public Health, Nicolaas P. Pronk

Frontiers in Public Health Services and Systems Research

Workforce fitness matters for the prevention of premature death, chronic diseases, productivity loss, excess medical care costs, loss of income or family earnings, and other social and economic concerns. Yet fitness levels appear to be relatively low and declining. Over the past half century obesity has doubled, physical activity levels are below par, and cardiorespiratory fitness often does not meet minimally acceptable job standards. During this time, daily occupational energy expenditure has decreased by more than 100 calories. It is recommended for employers to consider best practices and design workplace wellness programs accordingly. Regulations that protect and promote worker health, …

25-Hydroxyvitamin D, Igf-1, And Waist Circumference A Cross-Sectional Study, Damon Mccune

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose: Waist circumference has been shown to have a link to various forms of chronic disease and low levels of Vitamin D (25(OH)D) and IGF-1. The purpose of this study is to assess if there is a relationship with Vitamin D (25(OH)D) and IGF-1 levels and waist circumference.

Methods: As part of a cross-sectional correlation study, participants were males and females (n=26), ages 25-65, who were students at UNLV and/or individuals who attend local health and wellness facilities as well as attendees of classes held by the UNLV Nutrition Center. Participants reported to UNLV to review and sign informed consent …

Top 10 Research Questions Related To Energy Balance, Robin P. Shook, Gregory A. Hand, Steven N. Blair

Robin Shook

Obesity is the result of a mismatch between the amount of calories consumed and the amount of calories expended during an extended period of time. This relationship is described by the energy balance equation, which states the rate of change in energy storage depots in the body are equal to the rate of energy intake minus the rate of energy expenditure. Although this relationship may appear easy to understand based on simple mathematics, in reality, a variety of known and unknown systems influence the components of energy balance (energy storage, energy intake, energy expenditure). Clearly, if a complete understanding of …

A Community-Based Exercise Intervention Transitions Metabolically Abnormal Obese Adults To A Metabolically Healthy Obese Phenotype, Lance C. Dalleck, Gary Van Guilder, Tara B. Richardson, Donald L. Bredle, Jeffery M. Janot

Health and Nutritional Sciences Faculty Publications

Background: Lower habitual physical activity and poor cardiorespiratory fitness are common features of the metabolically abnormal obese (MAO) phenotype that contribute to increased cardiovascular disease risk. The aims of the present study were to determine 1) whether community-based exercise training transitions MAO adults to metabolically healthy, and 2) whether the odds of transition to metabolically healthy were larger for obese individuals who performed higher volumes of exercise and/or experienced greater increases in fitness. Methods and results: Metabolic syndrome components were measured in 332 adults (190 women, 142 men) before and after a supervised 14-week community-based exercise program designed to reduce …

Obesity-Related Hormones And Metabolic Risk Factors: A Randomized Trial Of Diet Plus Either Strength Or Aerobic Training Versus Diet Alone In Overweight Participants, Allan Geliebter, Christopher N. Ochner, Carl L. Dambkowski, Sami A. Hashim

Lander College of Arts and Sciences Publications and Research

There is debate about the additive effects of exercise in conjunction with diet to treat obesity, and not much is known about the differential effects of strength versus aerobic training. This randomized controlled trial examined the effects of diet plus strength training, diet plus aerobic training, or diet only on metabolic risk factors associated with obesity. Eighty-one overweight and obese participants completed the 8-week intervention. All participants received an energy-restrictive formula diet with an energy content based on 70% of measured resting metabolic rate (RMR). Participants assigned to an exercise group trained 3 days/week under supervision. Anthropometrics and fasting hormones …
