Multilevel Influences On Physical Activity Participation In Rural And Cancer Populations With Obesity, Nashira Inika Brown Jan 2022

Multilevel Influences On Physical Activity Participation In Rural And Cancer Populations With Obesity, Nashira Inika Brown

All ETDs from UAB

espite the strong evidence of physical activity benefits, the prevalence of physical inactivity and associated obesity continues to increase. Rural and cancer survivor populations with obesity, in particular, remain highly inactive and are at increased risk of comorbidities. Thus, physical activity interventions are needed to promote active lifestyles. However, before developing or adapting existing multi-level physical activity interventions, more research is needed to understand the necessary components to meet the needs and preferences of these unique populations. Therefore, this project involved identifying the gaps in literature followed by three studies to investigate the multilevel influences on physical activity in rural …


Nutritional And Metabolic Effects Of Elexacaftor/Tezacaftor/Ivacaftor In Adults And Adolescents With Cystic Fibrosis, Julianna Bailey Jan 2021

Nutritional And Metabolic Effects Of Elexacaftor/Tezacaftor/Ivacaftor In Adults And Adolescents With Cystic Fibrosis, Julianna Bailey

Background: Since malnutrition is a main clinical consequence of CF, a high-calorie, high-fat diet is recommended. Highly effective cystic fibrosis transmembrane conductance regulator (CFTR) modulators promote improved growth and weight gain in subsets of the CF population. Recently Elexacaftor/Tezacaftor/Ivacaftor (ETI) was approved for use in up to 90% of people with CF. Our single center open-label observational cohort study aimed to explore the changes in dietary and metabolic outcomes with use of ETI. Methods: Participants underwent baseline (V1) measurements prior to taking their first dose of ETI. Follow-up measurements were obtained at 28 days (V2) on ETI and > 6 months …


Multiracial Tobacco, Alcohol, And Drug Use: An Investigation Of The Function Of Racial Identity In A Longitudinal Sample From Youth To Young Adulthood, Julia Katrina Crumly Jan 2008

Multiracial Tobacco, Alcohol, And Drug Use: An Investigation Of The Function Of Racial Identity In A Longitudinal Sample From Youth To Young Adulthood, Julia Katrina Crumly

All ETDs from UAB

The purpose of the research is threefold. The first purpose is to determine if multiracial individuals are at a higher risk for alcohol, tobacco, and drug use. The second purpose is to determine the relationship between racial identity and risk behaviors. The third purpose is to determine how the change/no change of racial identity longitudinally contributes to one’s risk to engage in risk behaviors. A national representative longitudinal data set was obtained and analyzed for the purpose of this study. Results of the study reveal that there are differences in multiracial groups for risk behaviors, minority identification is not necessarily …
