Eat The Rainbow! An Evaluation Of A Short-Term Fruit And Vegetable Nutrition Education Intervention For Elementary School Children, Elizabeth Diane Miller

Masters Theses

Objective: To test differences on mean fruit and vegetable (FV) eaten, liking, preference, and self-efficacy scores among 3 modes of nutrition education intervention after a 3-week intervention.

Design: Convenience sample, pre- and post-test, quasi-experimental design.

Setting: Three elementary schools in a rural Eastern Tennessee County.

Participants: Participants were 160 3^rd-5^th graders.

Interventions: Three study schools: experiential (nutrition education, taste tests, and learning activity), conventional (nutrition education and learning activity), and control (learning activity).

Main Outcome Measures: Changes in pre- to post-intervention mean FV eaten, liking, preference, and self-efficacy scores.

Analysis: Mixed model ANOVA to compare the mean …

Nutritional Ergogenic Aids: The Influences Of Carbohydrate-Protein Supplementation During Endurance Exercise, Adriana Marina Coletta

Masters Theses

Mixed results, in terms of performance benefits, have been found when comparing carbohydrate (CHO) and carbohydrate-protein (CHO-P) supplementation during endurance exercise. Thus this study assessed performance from three different supplements (CHO-P, CHO, double carbohydrate [CHO-CHO]) as compared to a placebo (PLA) during a time trial (TT) run. Twelve male recreational runners (age = 32.4 ± 9.5 yrs; body mass index [BMI] = 22.7 ± 1.5 kg/m2; VO2max = 59.68 ± 7.53 mL/kg body weight; 100% white) individually completed four, 12-mile TT runs, 7-10 days apart, at about 75% of the their race pace. Dietary and physical activity consistency within the …

Angiotensin Iv And The Molecular Mechanisms Involved In The Development Of Insulin Resistance In 3t3-L1 Adipocytes, Julie Anne Jungwirth

Masters Theses

This study explored angiotensin IV’s (Ang IV) affects on the signaling pathways involved in the development of insulin resistance in 3T3-L1 adipocytes. Ang IV, working through the AT₄ receptor, interferes with insulin signaling through the blockade of the phosphatidylinositol 3-kinases (PI3K)/Akt pathway and through activating mitogen activated protein kinases (MAPK): extracellular signal regulated kinase (ERK) and c-Jun-N-terminal kinase (JNK) which are known to impair insulin receptor substrate-1 (IRS-1) signaling. The expression of AT₄ receptors was confirmed by reverse transcription polymerase chain reaction. Ang IV’s effects were found by treating adipocytes with combinations of Ang IV, AT …

Home Food Availability, Dietary Intake And Child Weight Status, Manasi Barot

Masters Theses

Background: Childhood obesity is a critical public health problem. There is a crucial need to identify environmental factors that either encourage or prevent obesogenic behaviors. The home food environment is one of the primary environments in which children are exposed to food. Therefore, it is crucial to study how the home food availability influences dietary intake and weight status. Objective: This study examines parental report of household food availability of fruits, vegetables, and milk, and its association with child weight status and child dietary intake of these foods. Methods: This is a cross-sectional study, based on surveys from 489 students …

Allometric Scaling Of Dietary Linoleic Acid On Changes In Tissue Arachidonic Acid Using Human Equivalent Diets In Mice, Kylie A Weldon

Masters Theses

The ability to extrapolate nutritional intervention data from experimental rodent models to humans requires standardization of dietary design. The inability to translate the level of nutrients from animal models to humans has contributed to contradictory findings between species. It is hypothesized that dietary linoleic acid (LA) promotes chronic and acute diseases by enriching tissues with arachidonic acid (AA), its downstream metabolite. However, levels of LA in rodent diets are notoriously erratic making interspecies comparisons unreliable. Therefore, the ability to extrapolate the biological effects of dietary LA from experimental rodents to humans necessitates an allometric scaling model that is rooted within …

Nutrition Knowledge And Child Care Feeding Practices Of Early Childhood Education Students: A Preliminary Study, Sarah Jill White

Masters Theses

The purpose of this study was to describe the nutrition knowledge and child care feeding practices of Early Childhood Education students in a university setting. Thirty-three Early Childhood Education students from seven geographically diverse universities completed a web-based survey assessing nutrition knowledge and child feeding practices. A nutrition knowledge instrument was developed and validated to measure knowledge of nutrition for preschool-aged children. The Comprehensive Feeding Practices Questionnaire, which has been previously validated in parents, was slightly modified and used to assess child feeding practices. Mean scores for the nutrition knowledge and child feeding practices were determined. Multivariate analyses were conducted …
