Dr. Zajacova’s research examines issues in population health, health inequalities, and social determinants of health over the adult life course. In particular, she aims to understand how educational experiences and attainment influence later-life health and longevity among adults and elderly. Some open central questions include: How do college experiences matter for health? Why is the high-school equivalency diploma (GED) associated with worse health than a standard high school graduation? Do adults who attended college but did not earn a credential benefit in terms of their health?
Additional topics Zajacova studies include
- Measurement properties of self-rated health: how do people assess their health?
- Excess body weight and its consequences over the lifecourse: under what circumstances is it detrimental?
- Health trends among US adults in 21st century: why are Americans becoming more sick?
