Hispanic immigrant, African American men have highest rate of workplace injury

Hispanic immigrant and African American men work in jobs with the highest risk of injury, according to a new study of workplace injuries and disability.

"We found that their risk was higher even when we accounted for education and other demographic characteristics," said lead author Seth Seabury, director of the Keck-Schaeffer Initiative for Population Health at the USC Schaeffer Center for Health Policy and Economics and Keck School of Medicine of USC. "Disparities in economic opportunities for minorities lead them to take more hazardous jobs that raise their risk of injury and disability."

For the study published in the February edition of Health Affairs, USC researchers found that men ages 18 to 64 who are Hispanic immigrants have the highest average workplace injury rate at 13.7 per 1,000 workers, followed by African American men (more than 12), and U.S.-born Hispanic men (nearly 12), white men (11.8), and Asian Americans (nearly 10). Other ethnicities have a rate of around 11 per 1,000 workers.

The researchers from USC Schaeffer Center, the Keck School of Medicine at USC and Boston University analyzed two sets of data that had similar demographic characteristics. One set, from the U.S. Census Bureau's American Community Survey from 2006 to 2013, included 11.6 million respondents. The other, the Survey of Income and Program Participation by the federal Bureau of Labor Statistics for years 1996, 2001, 2004 and 2008, included 198,000 respondents.

More injuries, more disability

A higher expected workplace injury rate is linked to an elevated risk of disability, but especially so for older workers ages 50 to 64, the researchers found. African Americans in this age bracket have a 4.4 percent rate of work-related disability, followed by foreign-born Hispanics (4.2 percent); Asian Americans (4 percent) and U.S.-born Hispanics (3.5 percent).

Older whites have the lowest disability rate - about 2.5 percent.

The researchers did not identify the underlying causes of the disparities, but discrimination has been a factor in poor worker safety throughout history. The study noted, for example, that a researcher, J. William Lloyd, more than 40 years ago found steel workers who were black were assigned to work the top-side of the coke ovens, and were consequently exposed to high levels of cancer-causing emissions.

"Historically, ethnic minorities have faced some of the worst job conditions," said Seabury, who is also an associate professor of ophthalmology at the Keck School of Medicine of USC. "The United States has made progress in reducing on-the-job injuries, but our findings indicate that disparities still exist. Minority workers experience worse health."

The researchers said that, because they focused on workplace injuries for this study, they may have fallen short of capturing the full extent to which working conditions can hurt the health of minority and immigrant workers.

Bias in the workplace

The researchers listed possible factors that may contribute to disparities in work-related injuries, such as a bias in assigning minority workers to the riskiest tasks, or discrimination in hiring and promotion.

"Based on our findings, policy makers and regulators may need to review whether employers are systematically assigning people of different races and ethnicities different jobs or job tasks according to their risk," the researchers wrote.

Investing more in lowering injury risk is expensive, and it could lead employers to lower wages or reduce job opportunities, the researchers noted.

"Care needs to be taken to ensure that efforts to make workplaces safer do not at the same time reduce economic opportunities for vulnerable populations," they wrote. "The issues raised here will only become more salient and politically charged as the U.S. population continues to become more diverse."
