Latin American Affairs

The purpose of the Latin America Affairs Section is to bridge the gap between obesity professionals in The Obesity Society (TOS) in North America and Latin America, specifically those interested in research development and collaborations within TOS and other regional societies in North, Central and South America. The main aim of the Section is to develop academic strategies, training opportunities, research collaborations, and continuing education courses for the Spanish and bi-lingual community.

Marcela Perez, M.Sc (Chair, 2014-2015)Marcela Perez

Centro Médico Nacional Siglo XXI Instituto Mexicano del Seguro Social

Dr. Perez is the Program Coordinator in the Clinical Research Training Center of the Mexican Institute of Social Security. Her research interest centers on investigating energy expenditure in obese pregnant women, the role of dietary and physical activity patterns impact on Obesity, Metabolic Syndrome and its components in children and adults. During her Master's degree program she studied the effect of very short, short, medium and long bouts of moderate to vigorous physical activity on adiposity in school age children. Contrary to what physical activity guidelines recommend, which is performing two bouts of 15 minutes each, her work showed that bouts lasting 10 minutes are associated with lower adiposity.

In her Doctoral program, she is currently working on a study looking at differences in dietary patterns associated with Metabolic Syndrome in normal weight, overweight and obese subjects.

Miriam Jacoma SosaMiriam Jacome Sosa, PhD (Early-Career Representative, 2014-2015)

Miriam Jacoma Sosa

University of Missouri, Department of Nutrition and Exercise Physiology

Dr. Jacome Sosa's research interest centers on investigating the impact of macronutrients on fatty acid and triglyceride metabolism during health and disease conditions (pre-diabetes and dyslipidemia) using an integrated physiology approach.

During her PhD program, she uncovered beneficial properties of a naturally occurring trans-fat called vaccenic acid on visceral adiposity and dysfunctional intestinal and hepatic lipid metabolism in a rat model of pre-diabetes. Her work showed for the first time that these metabolic benefits of vaccine acid are associated with its tissue-specific effects on lipid signaling pathways of the endocannabinoid system.

Dr. Jacome Sosa's postdoctoral training in Dr. Elizabeth Parks' laboratory will expand the understanding of how insulin resistance impacts intestinal lipid metabolism in humans. The project is utilizing stable isotopic techniques, GC/MS, and mathematical modeling to track the fate of nutrients (e.g. absorption/storage of carbohydrates and fat) in the human body. Specifically, they are testing whether intestinal signaling as a result of food taste is impaired in pre-diabetes.
