Much of the race-related research on chronic pain in the United States only compares Black and White Americans, leaving out many other ethnic groups and demographics.  

In an attempt to broaden our understanding of who experiences pain and why, researchers culled through eight years of public surveys conducted by the CDC and the U.S. Census Bureau from 2010 to 2018. These National Health Interview Surveys gathered information from White, Black, Hispanic, Asian, Native American and multiracial Americans, giving us new insight into the role of race in pain prevalence. 

“People often tend to think about pain as a personal issue or personal struggle, but it’s really a broad social and societal issue,” says Anna Zajacova, PhD, a sociology professor at the University of Western Ontario and lead author of Beyond Black vs White, a study recently published in the journal PAIN.       

In addition to race, Zajacova and her colleagues looked at socioeconomic factors such as education, family income, home ownership and whether someone was born in the U.S. or abroad.  They found that racial disparities in pain are far larger than previously recognized, with Native Americans nearly five times more likely to have severe pain than Asian Americans. Hispanics, Whites and Blacks fell between the two extremes.

Severe Pain Prevalence

• 2.4% Asian Americans

• 5.0% Hispanics

• 6.8% Whites

• 7.6% Blacks

• 8.7% Multiracial Adults

• 11.1% Native Americans

Why is there so much disparity between races? Researchers found that Asian Americans collectively had the highest levels of education and family income, giving them a socioeconomic advantage that may explain their lower pain prevalence. Native Americans, on the other hand, tend to be the most socioeconomically disadvantaged ethnic group, which is likely a factor in their high pain prevalence.

“We really need to understand what is causing the high pain among Native American and multiracial adults, and what factors protect Asian Americans from reporting high pain on average. This question will require delving into upstream causes such as discrimination, resulting stress and corollary health impacts, as well as the role of protective factors such as community and individual resilience,” Zajacova told PNN. 

While socioeconomic factors play a role, they're not always a deciding one. Hispanics reported less severe pain than White Americans despite having fewer socioeconomic advantages, indicating that other factors may be involved.

One may be place of birth. Researchers found that immigrants reported significantly less pain than native-born adults. Since about half of Hispanic adults are foreign born, that may help explain their lower incidence of pain -- or at least a reluctance to report it. 

Researchers say we need a better understanding of the racial, ethnic, social and economic issues that contribute to chronic pain if we ever hope to manage it.   

“The biopsychosocial model of pain predicts that people marginalized by social conditions would experience more pain. Our foundational results show more nuanced patterns, in which some minoritized groups show higher pain prevalence than Whites, whereas others show lower prevalence,” Zajacova wrote.

“Given that pain is arguably the most prevalent and costly public health condition in the United States, enhanced knowledge of racial and ethnic disparities in pain is urgently needed to inform policy decisions and focus efforts at population-level prevention and intervention.”
