Statistical Methods For Evaluating Confounding In Nutritional Epidemiology: Examining The Association Of Dietary Measures And Incident Type 2 Diabetes, Stephanie E. Tison

All ETDs from UAB

Nutrition is a key factor in the development of noncommunicable diseases (NCDs) such as cardiovascular disease, diabetes, obesity, and cancer, which are continuing to increase globally. Research on dietary patterns is crucial for informing what aspects of diet are most critical for preventing and possibly reversing chronic disease. Dietary patterns focus on the types of food that are consumed which reflects the complexity and cultural aspects of diet rather than focusing on a single food or nutrient. Observational cohort studies are able to observe typical dietary intake and thus better reflect the real association between diet and chronic disease. In …

Faculty, Staff and Student Publications

Studies have investigated the association between social vulnerability and SARS-CoV-2 incidence. However, few studies have examined small geographic units such as census tracts, examined geographic regions with large numbers of Hispanic and Black populations, controlled for testing rates, and incorporated stay-at-home measures into their analyses. Understanding the relationship between social vulnerability and SARS-CoV-2 incidence is critical to understanding the interplay between social determinants and implementing risk mitigation guidelines to curtail the spread of infectious diseases. The objective of this study was to examine the relationship between CDC's Social Vulnerability Index (SVI) and SARS-CoV-2 incidence while controlling for testing rates and …

Addressing The Needs Of African American Grandparents: An Intersectionality Perspective, Dorothy Smith-Ruiz, Kendra Jason
