Eating Frequency and Visceral Adipose Tissue, Body Fat, and Obesity Risk in Hispanic College Freshmen — FHS  

Obesity Clinical Trial

Official title: Freshman Health Study

Status Completed

Clinical Trial Summary

Due to the increased focus on education and changing lifestyle, college students are particularly susceptible to poor overall health and wellness due to inadequate sleep and poor dietary choices. This is particularly important because the behavioral choices college students make may affect their risk of chronic disease. This study will research these topics via an online survey, in person visit and stool sample.

Clinical Trial Description

It is important for college students to establish healthy habits during college because they are likely to stay with them throughout their lives. The transition to college has been identified as a critical period contributing to the rise in obesity rates. Several studies have shown that the initial transition to college is associated with rapid weight gain and the average weight gain in the first year of college ranges from 3.5 to 8.8 pounds. While decreased dietary fiber, fruits and vegetables and junk food consumption are among the dietary factors that have been linked to increased obesity rates in college students, little is known about the effect of eating patterns on health in this population. Furthermore, lack of sleep, smoking, binge drinking, and infrequent eating are all associated with negative health outcomes. Previous work with college age youth has found that several behaviors cluster together. The goal of the Online Survey portion is to expand on current findings, as well as examine the interrelationships of alcohol use, sleep, smoking, and eating patterns with adiposity and metabolic disease risk in a population of freshmen college students.

Eating frequency research has consistently found a negative association between the number of eating occasions (EOs) per day and adiposity, as well as metabolic disease risk in both youth and adult populations. Our group has shown that infrequent eating is linked to increased obesity measures, blunted insulin action, and deleterious lipid parameters in multiple populations of overweight Hispanic youth (8-18y). However, to date, no group has looked at the effect of eating frequency on adiposity and metabolic disease risk in a sample of overweight Hispanic college freshmen. In 2012, for the first time in history Hispanic high school graduates (69%) were more likely to be enrolled in college than Non-Hispanic Whites (NHW; 67%) and Blacks (63%) and last year Hispanic students represented 24% of freshman enrollment at the University of Texas at Austin (UT), Hispanics also showed the largest increase among all minority groups. Thus, the goal of the In-Person Visit is to examine the relationship between eating frequency and adiposity/metabolic disease risk in this extremely high-risk population of Hispanic freshmen and potentially identify interventions that may reduce this risk within such a crucial period of life.

The human body contains 100 trillion microbes, and microbial genes outnumber human genes 100:110. Over the past decade, interest in the complex ecosystem of gut microbiota has increased immensely and research has uncovered a relationship between gut microbiota, metabolic disease, and obesity. Both diet and obesity have been shown to alter the gut microbiota12,13. However, few studies have investigated how individual dietary components can affect the gut microbiota in humans. The Stool Sample portion of the study is an exploratory investigation of the relationship between dietary components and gut microbiota composition in college-aged Hispanic freshmen. ;
