This interesting study was conducted by Columbia University’s Mailman School of Public Health. Prior to this, scientists knew that low-paying jobs were directly linked to health outcomes such as depressive symptoms, obesity, and hypertension, which are risk factors for cognitive aging. But none of the previous studies have examined the specific relationship between low wages during the working years and cognitive ability later in life.
This paper provides new evidence that the persistent impact of low wages during peak earning years is associated with accelerated memory decline later in life. This association was observed both in the primary sample and in the control group.
The researchers divided study participants into those who never received low wages, periodically received low wages, or always received low wages based on wages received from 1992 to 2004, and then examined the association with memory decline over the next 12 years. years — from 2004 to 2016
The researchers found that compared to workers who never received low wages, those who consistently received low wages experienced significantly faster memory decline in old age.
“Our findings suggest that social policies that improve the financial well-being of low-wage workers may be particularly beneficial for cognitive health,” said senior author Adina Zeki Al Hazzuri, PhD and assistant professor of epidemiology.
