Added Sugar Consumption Among College Students, Maram Murad
Theses & Dissertations
Added sugar consumption has been increasing in all age groups in the United States and worldwide, with the greatest increase in young adults. College-age years are a critical period in the young adult's life where many habits develop, including nutrition and food choices. An understanding of college-age students’ attitudes and behaviors toward added sugar consumption might help predict added sugar consumption within this population. This was a quantitative study of traditional-aged college students' added sugar consumption through a convenience sample at a private university in San Antonio, TX. A survey was administrated to undergraduate students at different classes. Subjects ...

The Role Of Attitude, Control And Intention To Explain Fruit And Vegetable Intake Among Racial/Ethnic Minority Women With Low Socioeconomic Status, Michele Debiasse, Deborah J. Bowen, Sherry L. Pagoto, Joseph M. Massaro, N. Istfan, Lisa M. Quintiliani
Sherry L. Pagoto
Objective: Fruit and Vegetable (FV) intake-a modifiable risk factor for chronic diseases-is lower among racial/ethnic minorities and low Socio- Economic Status (SES) groups when compared to other populations. The Theory of Planned Behavior (TPB) is one theoretical model studied to explain and influence individual health behaviors, including FV intake, in middle class populations, but not exclusively in diverse, low SES groups. This cross-sectional study evaluated the utility of select TPB variables to explain intention to consume and intake of FV in this population.
Design: Demographics, BMI, select TPB variables, and FV intake were measured via survey. Bivariate analyses were ...
Adaptive Thermogenesis And Metabolic Changes Following Diet- And Exercise- Induced Weight Loss, 2017 University of Nebraska-Lincoln
Adaptive Thermogenesis And Metabolic Changes Following Diet- And Exercise- Induced Weight Loss, Alexandra R. Martin
Nutrition & Health Sciences Dissertations & Theses
With more than two-thirds of adults in the United States considered as overweight or obese, a myriad of weight loss programs and products that promise quick results have infiltrated the market. While many individuals successfully lose weight over the short term, almost half of the initial weight lost is regained within one year, indicating a general predisposition for weight cycling and fat replenishment. As weight is lost, fat-free mass (FFM) also decreases, and resting metabolic rate (RMR) declines, decreasing energy expenditure. After accounting for decreases in FFM, there remains a greater-than- predicted decrease in RMR, referred to as adaptive thermogenesis ...

Relationships Between Nutrition-Related Knowledge, Self-Efficacy, And Behavior For Fifth Grade Students Attending Title I And Non-Title I Schools, Elisha M. Hall, Weiwen Chai, Julie A. Albrecht
Nutrition and Health Sciences -- Faculty Publications
The Social Cognitive Theory (SCT) is a widely used theory for nutrition education programming. Better understanding the relationships between knowledge, self-efficacy, and behavior among children of various income levels can help to form and improve nutrition programs, particularly for socioeconomically disadvantaged youth. The purpose of this study was to determine the relationships between knowledge, self-efficacy, and behavior among fifth grade students attending Title I (≥ 40% of students receiving free or reduced school meals) and non-Title I schools (< 40% of students receiving free or reduced school meals). A validated survey was completed by 55 fifth grade students from Title I and 122 from non-Title I schools. Differences in knowledge, self-efficacy, and behavior scores between groups were assessed using t test and adjusted for variations between participating schools. Regression analysis was used to determine the relationships between knowledge, self-efficacy, and behavior. In adjusted models, the Title I group had significantly lower scores on several knowledge items and summary knowledge (P = 0.04). The Title I group had significantly lower scores on several behavior variables including intakes of fruits (P = 0.02), vegetables (P = 0.0005), whole grains (P = 0.0003), and lean protein (P = 0.047), physical activity (P = 0.002) and summary behavior (P = 0.001). However the Title I group scored higher on self-efficacy for meal planning (P = 0.04) and choosing healthy snacks (P = 0.036). Both self-efficacy (β = 0.70, P < 0.0001) and knowledge (β = 0.35, P = 0.002) strongly predicted behavior; however, only self-efficacy remained significant in the Title I group (self-efficacy, β = 0.82, P = 0.0003; knowledge, β = 0.11, P = 0.59). Results demonstrate disparities in nutrition knowledge and behavior outcomes between students surveyed from Title I and non-Title I schools, suggesting more resources may be necessary for lower income populations. Findings suggest that future nutrition interventions should focus on facilitating the improvement of children's self-efficacy
Gelatinization Properties Of Starches From Three Successive Generations Of Six Exotic Corn Lines Grown In Two Locations, Y. Ji, L. M. Pollak, S. Duvick, K. Seetharaman, Philip Dixon, Pamela J. White
The objectives of this research were to evaluate the intra- and interpopulation variability in gelatinization properties of starches from exotic corn lines and their derivatives when grown 1) during two successive years in the same location; and 2) in both temperate and tropical environments. Six novel exotic corn lines (two 100% exotic and four 25% exotic derived from a breeding cross developed by crossing an exotic hybrid with Corn Belt lines) were selected for this research because their starches have significantly different (and potentially useful) thermal properties from those found in starch from normal Corn Belt corn. The Sn (n ...

Background: Obesity is a major health concern in the United States. Omega-3 fatty acids (O3FA) have been observed to improve metabolic health and therefore might be useful in treatment of obesity. However, little is known regarding the effect of O3FA on school aged normal weight and overweight children.
Objective: The objective of this thesis was to determine if habitual intake of O3FA at breakfast improves energy metabolism, appetite, and metabolic response in overweight and obese school-aged children.
Design: Twenty healthy, normal weight (NW; n = 11) and overweight (OW; n = 9) children aged 8-12 years were randomly assigned to receive either ...
Whole Egg Consumption Attenuates Weight Gain In Obese Type 2 Diabetic Rats, 2017 Iowa State University
Whole Egg Consumption Attenuates Weight Gain In Obese Type 2 Diabetic Rats, Kaylee Hahn, Caitlyn Coonts, Carter Reed
Symposium on Undergraduate Research and Creative Expression
Obesity is a national epidemic that can increase an individual's risk for a multitude of health complications, including type 2 diabetes (T2D). In individuals already diagnosed with the disease, even small amounts of weight loss can help prevent diabetic complications. Due to the relationship between obesity and T2D, and the link between obesity and diet, a better understanding of how dietary factors affect those with T2D is necessary. Currently, the consumption of whole eggs by those with T2D is controversial. Here, we investigated the relationship between the consumption of whole eggs and obesity in both a genetic-mediated and diet-induced ...
