Hawkins Lab master’s student, Takashi Yoshimasu, MD, MPH, presented a research poster at the 2026 Epi in Action poster session, hosted by the University of Pittsburgh Department of Epidemiology.
Yoshimasu’s poster, “24-Hour Time-Use Behavior and Maternal Depression During Early Pregnancy,” drew on data from the Optimizing Health From Pregnancy Through One Year Postpartum (HABIT trial). He examined how time use is associated with depressive symptoms during pregnancy. The results showed no association with depressive symptoms; however, the research highlights the future direction of novel statistical methods on time-use behaviors.
