Human Equivalent Dose Modeling For Omega-3 Fatty Acid Supplementation In C57bl/6j Mice, Laura Louise Jones

Masters Theses

The rodent model is often used to study the impact of dietary n-3 fatty acids on a variety of biological endpoints, and the results of these studies have been used to explain anticipated effects of n-3 fatty acid intake in humans. However, supplemental levels of n-3 fatty acids that are commonly used in rodent studies do not represent reasonable human intake, by comparison. Currently there is no standard method for the addition of n-3 fatty acids to rodent diets. We tested a mathematical model for dosing supplemental levels of α-linolenic acid (ALA) and eicosapentaenoic acid (EPA) to rodent diets on …

Relationship Of School Breakfast Environment And Participation To Child Dietary Intake And Body Weight In Five Rural Appalachian Schools, Andrea Leigh Graves

Masters Theses

Objective The purposes of this study were two-fold: 1) to assess the school breakfast environment at four rural Appalachian schools for the contribution of foods to calories, fat, and fiber; and 2) to assess the dietary intake of students in these schools in relation to where breakfast was consumed (home, school, or both places) and by student weight status.

Setting Four rural Appalachian schools with fourth and fifth grade students in East Tennessee.

Subjects 255 fourth grade children completed a 24-hour dietary recall with a trained NDS-R interviewer and were weighed and measured by the Coordinated School Health Program.

The Relationship Between Social Desirability And Reported Dietary Intake In Healthy And Overweight Children, Nicolle Clemente

Masters Theses

Objective: The purpose of this study was to determine if social desirability bias existed in dietary recall data of fourth graders and if bias was related to child’s weight status and gender. It was hypothesized that children concerned with social desirability would report decreased total energy intake, percent calories from fat, and servings per day of sugar- sweetened beverages, candies, desserts, and meats, while showing an increase in reported servings per day of vegetables.

Subjects: The sample was a baseline evaluation of 255 fourth graders from rural, East Tennessee. The evaluation took place at the beginning of an intervention called, …

Breastfeeding Policies And Practices In Tennessee Hospitals, Carrie J. Barker

Masters Theses

Objectives: The purpose of this study was to identify the level of compliance to the Baby Friendly Hospital Initiative (BFHI) in hospitals in Tennessee, to identify differences in infant feeding policies and practices based on hospital ownership type and to identify if breastfeeding disparities are related to the infant feeding policies and practices of those hospitals.

Methods: Eighty hospitals/maternity centers were surveyed in Tennessee. Thirty-seven hospitals responded to a mailed survey relating to the hospital infant feeding policies and practices as defined by the WHO/UNICEF BFHI’s Ten Steps to Successful Breastfeeding. Compliance was modeled as a function of hospital …

Transcriptional Changes In Adipose Tissue Before And After The Onset Of Hyperphagia In The Zucker (Fa/Fa) Rat, Mary D. Brown

Masters Theses

The Zucker fatty (fa/fa) rat inherits a defective leptin receptor with impaired leptin signaling. Fatties grow at the same rate as their littermates for the first 22 days of age, and then suddenly begin to grow at a much higher rate. This corresponds with the emergence of robust hyperphagia in the fatty rat and leads to overt obesity within days. This striking change in energy balance regulation makes it possible to determine which sets of genes are regulated by the fatty mutation before and after the onset of hyperphagia. Genechip microarrays were used to screen inguinal adipose tissue mRNA from …
