Racism and the Life Course: Taking Time Seriously.

The adage "time is money" signifies that time itself is a major social resource, but the role of time as a determinant of health inequities remains underappreciated. Time is fundamental to health promotion and human agency, as in having time to exercise and maintain social relationships. Further, scarcity in time is related to stress and illness. Time is also racialized, such that racial/ethnic minorities often have less free time and suffer a time penalty in multiple facets of life. Such penalties manifest in problems such as greater time in prison or more time spent accessing services. We argue that time may be a social determinant of health that is shaped by racism across the life course. We focus on three aspects: time as age, time as exposure, and time as a resource and privilege. We distinguish between chronological age, biological age, and social age. We discuss issues of accelerated aging and potential interconnections with critical periods. We also examine racial inequities in time. By more deeply considering time, we may advance our understanding of racial inequities in health.
