Xi Zhu

Xi Zhu, PhD, is an affiliate at the UCLA Center for Health Policy Research and a professor of health policy and management at the UCLA Fielding School of Public Health.

Zhu uses quantitative and qualitative methods to explore questions in three broad areas: 1) how team design, team process, and quality improvement activities in health care organizations affect care quality and safety; 2) how market and policy environments affect health care organizations’ structures, strategies, and efficiency; and 3) how changes (e.g., quality improvement initiatives, innovations) are implemented in health care organizations and what strategies may facilitate the change processes. He is particularly interested in how the health delivery system responds to payment reform (including Medicare and Medicaid policies) and how policy provisions interact with system response to affect health outcomes. 

Zhu received his PhD in sociology from the University of Minnesota.

Neighborhood Socioeconomic Contexts Mediate the Association Between Adverse Childhood Experiences and Social Risk and Health Outcomes in Adulthood

This study explored how neighborhood socioeconomic contexts influence the relationships between childhood adversity (ACE) and adulthood social risk and health outcomes. Using data from the 2021 California Health Interview Survey (CHIS), authors analyzed a sample of 18,612 adults, representative of California's adult population. The Karlson-Holm-Breen (KHB) method decomposed childhood adversity's effects into direct and indirect effects mediated by neighborhood socioeconomic contexts in adulthood.

Findings: Higher ACE scores were associated with increased housing and food insecurity, and poorer self-rated health, particularly among individuals with four or more ACEs. The neighborhood socioeconomic context mediated a small but significant portion of the relationship between ACEs and the outcomes. Policy initiatives addressing ACEs should consider the importance of neighborhood contexts in addressing social risk and health outcomes.
