Obesity Reduces Left Ventricular Strains, Torsion, And Synchrony In Mouse Models: A Cine Displacement Encoding With Stimulated Echoes (Dense) Cardiovascular Magnetic Resonance Study, Sage P. Kramer, David K. Powell, Christopher M. Haggerty, Cassi M. Binkley, Andrea C. Mattingly, Lisa A. Cassis, Frederick H. Epstein, Brandon K. Fornwalt

Pediatrics Faculty Publications

BACKGROUND: Obesity affects a third of adults in the US and results in an increased risk of cardiovascular mortality. While the mechanisms underlying this increased risk are not well understood, animal models of obesity have shown direct effects on the heart such as steatosis and fibrosis, which may affect cardiac function. However, the effect of obesity on cardiac function in animal models is not well-defined. We hypothesized that diet-induced obesity in mice reduces strain, torsion, and synchrony in the left ventricle (LV).

METHODS: Ten 12-week-old C57BL/6 J mice were randomized to a high-fat or low-fat diet. After 5 months on …

Reimagining My Body, Center For Public Service

SURGE

I stood there, shoulders slouched, elbows locked, hands glued to the side of the toilet. My body convulsing, I told myself, “this is the last time, just one more time and you’ll get back on track tomorrow.” It wasn’t the last time. I had been forcing myself to purge for months at this point, and each time I hated myself for it.

It was something I couldn’t control. It wasn’t out of a need for attention as so commonly thought, but a pure need to be the unreachable level of thin that I thought would make me beautiful. I was …

The Concomitant Relationship Shared By Sleep Disturbances And Type 2 Diabetes: Developing Telemedicine As A Viable Treatment Option, Pennie S. Seibert, Jennifer Valerio, Codieann Dehaas

Psychological Sciences Faculty Publications and Presentations

Individually, sleep disturbances and type 2 diabetes pose pervasive challenges to health. In addition, the negative symptomology associated with each condition is exacerbated further when presenting concomitantly. This relationship formulates a destructive loop wherein those with diabetes experience decreased sleep quality, which, in turn, worsens a wide range of health threats experienced by those with diabetes, including obesity and glucose intolerance. Because major lifestyle changes and daily care are needed to effectively manage both diabetes and sleep disturbances, an efficient and timely modality of treatment is essential. Advanced technology incorporating telemedicine and telehealth has the potential to enhance treatment by …

Stress And Eating: A Dual Role For Bombesin-Like Peptides, Zul Merali, S. Graitson, J. C. Mackay, P. Kent

Brain and Mind Institute

The current obesity "epidemic" in the developed world is a major health concern; over half of adult Canadians are now classified as overweight or obese. Although the reasons for high obesity rates remain unknown, an important factor appears to be the role stressors play in overconsumption of food and weight gain. In this context, increased stressor exposure and/or perceived stress may influence eating behavior and food choices. Stress-induced anorexia is often noted in rats exposed to chronic stress (e.g., repeated restraint) and access to standard Chow diet; associated reduced consumption and weight loss. However, if a similar stressor exposure takes …

How To Get Rid Of Thunder Thighs, Helena E. Yang

SURGE

I appreciate the insightful and important things your muffin top has to say to me, but my thunder thighs still think they’re fat.

I’m overweight (sometimes).

On a BMI scale, I fluctuate in and out of the dreaded “overweight” category. While I acknowledge that the BMI scale has its flaws, it was designed to be a quick approximation of weight to height; it is not designed to be a scientific test. Sometimes I tell myself I am super muscular and the scale doesn’t apply to me, but it’s actually not true. [excerpt]

Obesity Indicators By Race/Ethnicity For Diagnosis Of Cardiometabolic Diseases For A Us Representative Sample Of Adults, Joan A. Vaccaro, Fatma G. Huffman

Department of Dietetics and Nutrition

Background: Obesity, a growing epidemic, is a preventable risk factor for cardiometabolic diseases. Obesity and cardiometabolic diseases affect Hispanics and African Americans more than non-Hispanic Caucasians. This study examined the relationship among race/ethnicity, obesity diagnostic measures (body mass index, waist circumference, subscapular and triceps skinfold thickness), and cardiometabolic risk factors (hyperglycemia, high, non-high-density lipoprotein cholesterol, low, high-density lipoprotein cholesterol, and hypertension) for adults across the United States.

Methods: Using data from two-cycles of the National Health and Examination Survey (NHANES) 2007-2010, and accounting for the complex sample design, logistic regression models were conducted comparing obesity indicators in Mexican Americans, other …

Community Built Environment And Multilevel Social Determinants Of Obesity: Evidence From China Health And Nutrition Survey, Libin Zhang, Tim F. Liao, Laura L. Hayman

Office of Community Partnerships Posters

The prevalence of overweight and obesity is highest in wealthy countries like the United States, but is rapidly increasing in less developed countries. From 1992 to 2002, China had an increase from 14.6% to 21.8% in overweight and obesity. Social determinants of obesity in developing countries remain poorly understood. Further, these associations may vary by community built environment (BE) of developing countries.

Cancellation Of Scheduled Exercise And Its Influence On Consumption: Exercisers Vs. Sedentary Individuals, Kayla A. Lange

Antonian Scholars Honors Program

Faculty of Science, Medicine and Health - Papers: part A

Private-sector organizations play a critical role in shaping the food environments of individuals and populations. However, there is currently very limited independent monitoring of private-sector actions related to food environments. This paper reviews previous efforts to monitor the private sector in this area, and outlines a proposed approach to monitor private-sector policies and practices related to food environments, and their influence on obesity and non-communicable disease (NCD) prevention. A step-wise approach to data collection is recommended, in which the first ('minimal') step is the collation of publicly available food and nutrition-related policies of selected private-sector organizations. The second ('expanded') step …
