Can Childhood Stress Affect the Immune System?

Whether it’s growing up in gut-wrenching poverty, dealing with dysfunctional family dynamics, or coping with persistent bullying in school, extreme adversity can shatter a child’s sense of emotional well-being. But does it also place kids at higher of developing heart disease, diabetes, and other chronic health conditions as adults?

Katherine Ehrlich, a researcher at University of Georgia, Athens, wants to take a closer look at this question. She recently received a 2018 NIH Director’s New Innovator Award to study whether acute or chronic psychosocial stress during childhood might sensitize the body’s immune system to behave in ways that damage health, possibly over the course of a lifetime.


Creative Minds: Considering the Social Determinants of Health

When Sanjay Basu was growing up in Arizona in the 1980s, his mother contracted a devastating lung infection known as valley fever. Caused by a fungus (called Coccidioides) common in the southwest United States, the condition often affects construction or agricultural workers who inhale the fungal spores while working the soil. Basu’s mother didn’t work in agriculture or construction, but the family did happen to live near a construction site. She spent about nine years in and out of intensive care units battling her illness. She survived, but still has difficulty breathing.

This wrenching experience gave Basu a first-hand appreciation for the social determinants of health—the conditions in which people live and the myriad internal and external forces that dynamically shape them. Now an assistant professor at Stanford University, Palo Alto, CA, Basu has dedicated his career to studying the social determinants of health disparities, health differences that adversely affect disadvantaged populations. He recently received an NIH Director’s New Innovator Award to examine U.S. social assistance programs and their effects on a range of health outcomes over the last 40-plus years. He’ll consider eight federal and state programs—including income, housing, and food assistance programs—that reach more than 1 in 3 Americans.
