The data showed that people who earned less than two-thirds of the median wage - $27,000 (£22,100) - in the US, suffered quicker memory loss than peers on a better salary. The jobs typical
Jobs that fall in this category include entry-level cleaners, fast food workers and teaching assistants. Lead scientist Dr Katrina Kezios said:
Sustained exposure to low wages during peak earning years is associated with accelerated memory decline later in life.
Implications
Results from the study, published in the Journal of Epidemiology showed that people on consistent low wages during the prime of their careers had significantly faster cognitive decline in later years. Those on lower wages throughout the 12-year period saw 10 per cent more decline than those on better wages, DailyMail noted.
The study fell short of outlining the reasons why low wages are linked to cognitive decline, but previous studies suggest it could be due to unhealthy dietary and lifestyle choices that people in this wage bracket tend to make. Senior author Dr Adina Zeki Al Hazzouri said:
Our findings suggest social policies that enhance the financial well-being of low-wage workers may be especially beneficial for cognitive health.
