Working for low wages makes your brain age faster, study reveals

NEW YORK — Working for minimum wage may be more harmful for your brain than it is for your wallet! A new study finds that continuously working for low wages leads to significantly faster memory decline. Simply put, when someone works a low-paying job, their brain ages faster than someone making a good salary.

Researchers at Columbia University note that previous studies have linked low-wage jobs to depressive symptoms, obesity, and hypertension. All of these conditions increase a person’s risk of accelerated cognitive aging.

“Our research provides new evidence that sustained exposure to low wages during peak earning years is associated with accelerated memory decline later in life,” says Katrina Kezios, PhD, a postdoctoral researcher at Columbia University Mailman School of Public Health, in a media release.

Using records from the national Health and Retirement Study (HRS) on adults between 1992 and 2016, the team examined data on 2,879 people born between 1936 and 1941. Researchers defined “low-wage” as hourly pay that was less than two-thirds of the federal median wage during that particular year.

From there, Kezios and her team separated each participant’s history of earnings into specific categories. Those groups included people who never worked for low wages, those who intermittently earned low wages, and those who continuously worked a low-wage job between 1992 and 2004.

Study authors then examined the relationship between these wages and memory decline over the next 12 years, between 2004 and 2016.

Minimum wage work takes a year off your brain’s life

Results show that, compared to people who never worked for little pay, sustained low-wage earners experienced significantly faster memory decline during old age. Specifically, low-wage workers experienced roughly one extra year of cognitive aging over a 10-year period. This means that for every 10 years of normal cognitive aging the average person experiences, a low-wage worker sees their brain age 11 years.

Researchers note that the federal minimum wage has stayed at $7.25 per hour since 2009. While economic growth has generally increased steadily since then, wage and salary growth has failed to keep pace — especially among minimum and low-wage workers.

“Increasing the federal minimum wage, for example to $15 per hour, remains a gridlock issue in Congress,” Kezios says.

“Our findings suggest that social policies that enhance the financial well-being of low-wage workers may be especially beneficial for cognitive health,” adds senior author Adina Zeki Al Hazzouri, PhD, an assistant professor of epidemiology at Columbia Mailman School and the Columbia Butler Aging Center. “Future work should rigorously examine the number of dementia cases and excess years of cognitive aging that could be prevented under different hypothetical scenarios that would increase the minimum hourly wage.”

The findings appear in the American Journal of Epidemiology.

  1. It’s not the low wage but the low IQ.
    Stupid people do stupid things like eat crap foods, sit around watching TV and over indulging in alcohol and other vices they can ill afford. Further, they don’t exercise and are not proactive when it comes to health and wellness.
    Of course their brains age faster right along with the rest of their bodies.
