Dr. Zenk studies social inequities and health, with the goal of identifying effective approaches at multiple levels to improve health and eliminate racial/ethnic and socioeconomic health disparities. Through pioneering research on food deserts and a team science approach, Dr. Zenk and her colleagues helped bring national attention to the problem of inadequate access to healthful foods in low-income and black neighborhoods. Dr. Zenk's teams have since produced crucial evidence on the health implications of these neighborhood inequities, including by leveraging electronic health record data. Using quasi-experimental study designs, they examine how intervention effectiveness depends on environmental context and evaluate policy changes. Recognizing that a sole focus on residential environments may mischaracterize environmental exposures and lead to misdirected or bypassed interventions, other research expands environmental measurement to include “activity spaces”. They use a variety of mobile sensors in this and other work to understand relationships among the environment, psychosocial factors, and health behaviors. Dr. Zenk collaborates on research and mentors students on a wide range of social determinants of health.

A Dynamic Environmental Exposure Approach to Study Health Behaviors in Midlife
Our objective is to combine real-time data collection approaches (e.g., GPS tracking, smartphone surveys, food images, accelerometry) to understand how activity-space environmental exposures and personal trait and state factors (e.g., executive functioning, stress) interact to influence dietary and physical activity behaviors during midlife. We hypothesize: (a) Activity-space environmental exposures (e.g., healthful food availability, recreational resource availability) contribute to both between- and within-person variations in dietary and physical activity behaviors and more strongly influence these behaviors than residential neighborhood environments alone, and (b) Activity-space environmental exposures are more consequential for diet and physical activity when self-regulatory capacity—trait or state factors that affect a person’s ability to make efforts to regulate behavior—is diminished. We will engage approximately 500 African American, Latinx, and white adults aged 40-64 who live in Cook and DuPage Counties.
