Assessing Feasibility And Readiness To Address Obesity Through Policy In American Indian Reservations, Valarie Blue Bird Jernigan, Gail Boe, Carolyn Noonan, Leslie Carroll, Dedra Buchwald

Journal of Health Disparities Research and Practice

The Institute of Medicine and Centers for Disease Control and Prevention (CDC) have identified policy and environmental strategies as critical to the prevention and control of obesity. However such strategies are rare in American Indian communities despite significant obesity-related disparities. Tribal policymaking processes differ by tribal nation and are often poorly understood by researchers and public health practitioners, hindering the dissemination, implementation, and successful scale-up of evidence-base obesity strategies in tribal communities. To address these gaps in knowledge we surveyed 138 diverse stakeholders in two American Indian reservations to assess the feasibility of and readiness to implement CDC-recommended obesity policy …

The Contributions Of Skeletal Muscle Pkc Theta To Diet-Induced Obesity, Erika Harness, Joseph S. Marino, Phd, Yvette Huet, Phd

Journal of Health Disparities Research and Practice

Protein Kinase C- Theta (PKCθ) is a gene predominantly expressed in hematopoietic cells and skeletal muscle. In skeletal muscle, PKCθ regulates fat metabolism and insulin sensitivity. PKCθ activity increases in response to high levels of diacylglycerol in the cell, a common outcome of chronic high fat diet consumption and obesity. PKCθ is associated with skeletal muscle metabolic dysfunction, which may exacerbate weight gain and metabolic disease. The purpose of this study was to test the hypothesis that the selective deletion of PKCθ from skeletal muscle protects against diet-induced obesity.

Mice lacking PKCθ in skeletal muscle were created using Cre-Lox recombination. …

An Intervention To Promote Navajo Gardening, Nutrition, And Community Wellness, Sonia Avitia, Mark C. Bauer, Phd, Linda Garcia

Journal of Health Disparities Research and Practice

The rates of diabetes and obesity in Navajo communities are higher than national rates. A healthy diet of fresh fruits and vegetables will help to prevent and reduce such rates. So the project focuses on promoting gardening to make vegetables and fruits more accessible at the comfort of one’s own home. Previous research in this area shows that gardeners consume 2 more servings of fruits and vegetables than nongardeners. Thirty participants were recruited by flyer distribution at chapter houses, senior centers, and community centers, from four Navajo targeted areas: Shiprock, NM; Tsaile, AZ; Lukachukai, AZ, and Hogback, NM. With the …

Leptin Induces Proliferation And Notch Expression In Pancreatic Cancer, Felice Watson, Ruben Gonzalez-Perez, Phd

Journal of Health Disparities Research and Practice

Pancreatic adenocarcinoma (PA) is an aggressive cancer. It develops in a way that causes almost no detectable symptoms, which leads to a rapid progression and a short survival rate.

Researchers have discovered a link between pancreatic cancer (and other cancer types) and obesity. High levels of leptin, an appetite hormone secreted by adipocytes, have been found in obese people. Studies have shown that the absence of leptin in the body or severe leptin resistance can lead to uncontrolled eating and weight gain, hence, its connection to obesity. Consequently, our lab is analyzing the relationship between obesity and leptin and what …

Exploration Of Antagonist Efficacy For Lpra2 Like Peptide, Ayobami Loye, Ruben R. Gonzalez-Perez, Phd

Journal of Health Disparities Research and Practice

Leptin is a small protein hormone that controls satiety and is produced by adipocytes. Obese people have increased levels of circulating leptin. Excessive leptin levels cause a break down in the control of leptin signaling pathways leading to increased angiogenesis, proliferation, cell migration, invasion, and anti-apoptotic events. Obesity and leptin signaling have been linked to cancer progression. Literature shows that LPrA2 is an effective leptin antagonist as it decreases proliferation of breast cancer cells in vitro.

This project compares the effectiveness of LPrA2 like compounds in breast cancer cell-line MDA-MB-468 (M-468 BCs). We hypothesize that the new peptide antagonists have …

Have You Counted The Ingredients On Your Child's Lunch Tray?: An Economic Analysis Of Sustainability Initiatives Within The School Lunch Program, Vanessa R. Scalora

Business and Economics Summer Fellows

In 2010, President Obama signed the Healthy Hunger Free Kids Act, establishing a monetary incentive for schools that served meals following a more rigorous nutritional requirement than standard guidelines. This act is a step in the right direction towards placing more importance on school lunches, however America’s lunchroom practices continue to be environmentally unsustainable, and students absorb this message. The production and transportation of processed cafeteria food contributes to climate change, its packaging is polluting, and its consumption contributes to obesity. The use of premade foods and sales from vending machines increase as lunch times grow ever shorter. In addition, …

The Information-Motivation-Behavioral Skills Model: An Examination Of Obesity Prevention Behavioral Change In Children Who Participated In The Afterschool Program Virginia Beach Let’S Move, Marilyn Miroshlava Bartholmae

Health Services Research Dissertations

The purpose of this study was to examine the utility of the Information-Motivation-Behavioral Skills Model (IMB) as a foundation to design childhood obesity prevention afterschool programs. This study employed a secondary analysis of pre (n=172), post (n=170), and 1-year follow-up (n=32) evaluations of the obesity prevention afterschool program Virginia Beach Let’s Move for children ages 5-11 years. Independent variables included demographic characteristics for the participating children and their parents. Dependent variables used in this study were the IMB constructs information and motivation. Motivation was measured by the attitudes of the children and information was measured by the children’s knowledge.

The …

Project Energize: Intervention Development And 10 Years Of Progress In Preventing Childhood Obesity Public Health, Elaine Rush, Carolyn Cairncross, Margaret Hinepo Williams, Marilyn Tseng, Tara Coppinger, Steph Mclennan, Kasha Latimer

Publications

Prevention of childhood obesity is a global priority. The school setting offers access to large numbers of children and the ability to provide supportive environments for quality physical activity and nutrition. This article describes Project Energize, a through-school physical activity and nutrition programme that celebrated its 10-year anniversary in 2015 so that it might serve as a model for similar practices, initiatives and policies elsewhere. The programme was envisaged and financed by the Waikato District Health Board of New Zealand in 2004 and delivered by Sport Waikato to 124 primary schools as a randomised controlled trial from 2005 to 2006. …

African American Single Mothers' Perceptions Of Physical Activity, Sheryl Lynn Richard

Walden Dissertations and Doctoral Studies

Insufficient physical activity detracts from healthy living and has a disparate impact on African American women and their female children. The extensive body of prior research addressing preventable chronic disease and other consequences of insufficient physical activity includes limited information specific to African American single mothers. The purpose of this descriptive phenomenological study was to gain an understanding of African American single mothers' perceptions of physical activity. Specifically investigated were African American women's familial influences and potential effects of these influences on their children's health behaviors. The health belief model served as the theoretical framework for this study and provided …

The Relationship Between Physical Fitness And School Performance In Middle School Girls, Jamie Anne Donnelly

Walden Dissertations and Doctoral Studies

Past research has indicated a significant relationship between physical fitness and standardized test scores; however, the relationship between physical fitness and other aspects of school performance has yet to be empirically examined in a population specifically composed of middle school girls. This study examined several factors that contribute to school success, such as classroom behavior, attendance, and grades, in relation to physical fitness among a group of adolescent girls. It was specifically designed to examine the statistical relationship between physical fitness, as measured by the Fitnessgram, and quantitative data on school performance including grades, standardized test scores, school behavior, and …
