The Epi Seminar Series is a UW Department of Epidemiology-sponsored seminar series for students, staff, and faculty, as well as practicing professionals in the field. Speakers and topics are selected to highlight the diversity of research ongoing in the department. Please visit our website to see our full schedule of seminars this quarter: http://bit.ly/episeminar

June 1, 2021 - Studying the Association of Maternal Mental Health and the Built Environment Using Health Informatics, Dr. Yiye Zhang
How does the urban built environment associate with patterns in prenatal care and maternal mental health? In a retrospective cohort study, we proposed a machine learning framework for postpartum depression (PPD) risk prediction using data extracted from electronic health records linked with address-based metrics on the built environment. The model performances as measured by area under the receiver operating characteristic curve (AUC) were 0.937 (95% CI 0.912 - 0.962) and 0.886 (95% CI 0.879-0.893) in the development and validation datasets, respectively. Examining predictors of PPD, we discovered 3 types of prenatal healthcare trajectories whereby the incidence of PPD was 6.65%, 2.67%, and 1.12%, respectively. The prenatal healthcare utilization trajectory with higher PPD rates was associated with lower-quality built environment factors including homogeneous land use, lower walkability, and lower accessibility. The quality of the built environment may be an important factor driving healthcare utilization patterns that lead to health disparities in postpartum depression risk.
