Low-wage workers may experience memory decline faster
Research on the effects of lower income on health is expanding rapidly. Using records from the National Health and Retirement Study (HRS) of adults for the years 1992-2016, the researchers analyzed data from 2,879 people born between 1936 and 1941.
Low wages are defined as hourly wages less than two-thirds of the federal median wage for the respective year. The researchers classified the low-wage histories of the study participants into those who never earned low wages, intermittently low wages, or consistently earned low wages based on wages earned since 1992. 2004 and then looked at the relationship with memory decline over the next 12 years from 2004 to 2016.
They found that, compared with never-low-wage workers, consistently low-wage workers experienced significantly faster memory decline at an older age. They experience about an excessive year of cognitive aging every 10 years.
While economic growth has picked up since then, growth in wages and wages for workers – especially those in low-wage jobs – has slowed over time and minimum wages have not kept pace. inflationary.
These findings suggest that Social policies that enhance the financial well-being of low-wage workers may be particularly beneficial for cognitive health..
Future work should closely examine the number of cases of dementia and years of cognitively excessive aging that could be prevented under various hypothetical situations that would raise the minimum hourly wage.
