Angiotensin At2r Activation Increases Ace2/Ang1-7/Masr Axis And Prevents Fatty-Diet-Induced Obesity, Sourashish Nag, Quaisar Ali, Yonnie Wu, Tahir Hussain

International Journal of Exercise Science: Conference Proceedings

Purpose: Adipose tissue, the obligatory site of fat accumulation causing obesity, expresses local renin angiotensin system (RAS). RAS is commonly known to regulate blood pressure. However recently, we observed that angiotensin type 2 receptor (AT2R) activation prevents high-fat diet (HFD)-induced adiposity and hyperinsulinemia. Although, the mechanism(s) is(are) not known. There is evidence that other RAS components namely, the angiotensin type 1 receptor (AT1R) positively regulates while the angiotensin converting enzyme 2 (ACE2), which catalyzes the production of Mas receptor (MasR) peptide agonist Ang (1-7), inversely regulates adiposity and hyperinsulinemia. In light of the RAS inter-regulatory features, we hypothesize that AT2R …

Race & Gender Disparities In The Embedding And Accumulation Of Childhood Poverty On Young Adult Bmi, Daphne C. Hernandez, Emily Pressler

International Journal of Exercise Science: Conference Proceedings

Purpose: A disproportionate number of race/ethnic minorities are both impoverished and overweight compared to white populations. Experiencing poverty during childhood is positively correlated with being obese in adulthood, especially for females. However, it is unclear whether it is the embedding of childhood poverty (i.e. timing of childhood poverty in relation to children’s stage of development) or the accumulation (i.e. duration) of the exposure to childhood poverty which contributes to the race and gender disparities in young adult body mass index (BMI). Method: Data from the 1979 National Longitudinal Study of Youth and the Children and Young Adult file were used …

Development And Comparison Of Two Field-Based Body Fat Prediction Equations: Nhanes 1999-2004, Michael Zanovec, Jing Wang, Carol E. O'Neil

International Journal of Exercise Science

International Journal of Exercise Science 5(3) : 223-231, 2012. Clinical guidelines define obesity in terms of excess body weight adjusted for height (i.e., bodymass index [BMI] categories) and/or gender-specific waist circumference (WC) cut-point values. Since body composition, particularly fat mass, is the most variable among individuals due to differences by gender, age, and race, and total percent body fat (%BF) can be estimated accurately using dual-energy X-ray absorptiometry (DXA), the purpose of this study was to develop and compare two field-based body fat prediction equations suitable for a nationally representative sample of the US adult population. Data were analyzed from …

C-Reactive Protein And The Disease Analog Model May Identify Predisposed Pre-Obese African-American Women, James W. Navalta, Scott Lyons, Sharon E. Whitlock, Demetrice D. Kirkwood, Scott W. Arnett, Mark A. Schafer

International Journal of Exercise Science: Conference Proceedings

While the obesity rate in the Unites States has been reported to have hit a plateau, the overall percentage of obese Americans remains alarmingly high (27% self-reported, 33% population estimate). While the subgroup with the highest 2010 obesity rate is Black, non-Hispanic women (41.9%), there remains a disparity in the research with regards to this population group. The implication of an elevated obese population puts a strain on health care, overall quality of life, and is associated with a number of other co-morbidities. Given this background, pilot work to evaluate a disease analog model for obesity would be useful with …

Childhood Overweight Is Associated With Increased Monocyte Concentration And Altered Subset Distribution, Whitney L. Breslin, Craig A. Johnston, Kelley Strohacker, Katie C. Carpenter, Tiffany Davidson, Jennette Palic, Brian K. Mcfarlin, John P. Foreyt

International Journal of Exercise Science: Conference Proceedings

Childhood obesity rates have nearly tripled in the last 30 years. Obesity increases risk for chronic disease. While monocytes, cells of the innate immune system that are altered with obesity, are purported to play an integral role in the development of these chronic diseases, no research has focused on early phenotypic changes in monocytes of overweight children. Two monocytes subsets exist, classic and pro-inflammatory; alterations in number and distribution may be implicated in disease development in obesity. The purpose of this study was to examine the concentration and relative distribution of monocytes among “normal weight” (N=66) and “at risk for …

Cognitive Behavior Modification And Exercise + Group Counseling For Patients After Bariatric Surgery, Janet Buckworth, Caroline Carducci, Shirley Kindrick, Dean Mikami, Dara Schuster, Katharine Stough, Bradley Needleman

International Journal of Exercise Science: Conference Proceedings

The growing obesity epidemic is paralleled by an increasing number of bariatric surgeries. Patients lose significant weight within the first 12-18 months post-surgery with corresponding resolution of many co-morbidities. However, weight loss stabilizes after 18-24 months and 50% or more of patients eventually regain weight (Bond, Phelan, Leahey, Hill, & Wing, 2009; Magro, et al., 2008). Weight regain after loss is associated with return of co-morbidities and deteriorations in health-related quality of life and mood (Karlsson, Taft, Ryden, Sjostrom, & Sullivan, 2007). The purpose of this pilot study was to analyze the effects of a post-surgical behavioral plus counseling intervention …
