Dr. Showell is dedicated to research focused on eliminating child obesity disparities. Specifically, her overarching goal is to conduct research that leads to the development and implementation of effective multi-level obesity interventions that address obesity disparities among low-income and minority children.
Dr. Showell has served as the project director of a mixed-methods study examining how neighborhood-level factors interact with low- income racial and ethnic minority parents' culture and personal preferences to influence child diet and physical activity behaviors. Additionally, she has served as a co-investigator on an Agency for Healthcare Research and Quality (AHRQ)-funded systematic literature review on the comparative effectiveness of child obesity interventions and has published the findings of her focused review of home-based obesity interventions.
