Effect Of Diet, Age, And Genetics On Rainbow Trout Growth And Fillet Quality, Bahareh Adami

Graduate Theses, Dissertations, and Problem Reports

In this study, analyses were conducted to compare fillet quality attributes of 4 rainbow trout families (40, 102, 159, and 187) fed fish meal (FM) and a fishmeal free diet (FMF), to two age endpoints, 9 and 11 months.

Previous studies with rainbow trout have evaluated the effect of age, diet, and family on growth performance and fillet quality. However, a comprehensive analysis of variables is lacking for rainbow trout, one of the main aquatic foods for domestic and international consumers.

Separable muscle as a percent whole body weight was not affected by diet, family, age, and the interaction of …

Evaluation Of A Telenutrition Weight Loss Intervention Among Middle-Aged And Older Men In Appalachia, Afnan Majed Alamoudi

Graduate Theses, Dissertations, and Problem Reports

Obesity rates among middle-aged and older men in WV are among the highest in the nation. Understanding baseline and intervention factors contributing to losing clinically significant weight are essential to developing effective interventions in target groups. Thus, the purpose of this study is to determine factors associated with losing ≥ 5% of baseline weight among participants of a 12-week pilot randomized controlled telenutrition trial for middle-aged and older men in WV. The study analyzed data from 56 participants who completed the trial. Participants were classified as losing ≥ 5 % or < 5 % of baseline body weight. Diet quality was assessed using 4-day diet records and the Healthy Eating Index (HEI)-2015. Baseline factors and behavioral strategies (i.e., self-monitoring, self-efficacy, and social support) were assessed via survey. Inverse prediction analysis demonstrated that participants who lost ≥ 3.5% of baseline weight at 6 weeks were at least 75% likely to lose ≥ 5% weight at 12 weeks. Predictive models were developed using stepwise logistic regression to assess multiple predictors of losing ≥ 5% of baseline weight at 12 weeks and ≥ 3.5% of baseline at 6 weeks. Weight loss at 6 weeks was a strong predictor of weight loss at 12 weeks, in addition to previous weight loss attempts and weekly self-weight-monitoring (p

The Application Of Systems Science In Nutrition-Related Behaviors And Outcomes Implementation Research: A Scoping Review, Ayron E. Walker, Rachel A. Wattick, Melissa D. Olfert

Faculty & Staff Scholarship

Use of systems science can improve the dissemination and implementation (D&I) process. However, little is known about use of systems science in nutrition D&I research. The purpose of this article is to synthesize the ways in which systems science methodology is applied in nutrition D&I research. Scoping review methodology involved searching 6 academic databases for full-text, peer-reviewed, English articles published between 1970 and 2020 that employed systems science within nutrition D&I research. Data extraction included intervention type, population, study aim, methods, theoretical approach, outcomes, and results. Descriptive statistics and qualitative thematic analysis followed. Thirty-four retained articles qualitatively identified benefits (successful …
