Washington: Researchers have said that a mentally demanding job may stress you out but could provide benefits after you retire.

Gwenith Fisher, a faculty associate at the University of Michigan Institute for Social Research and assistant professor of psychology at Colorado State University, said that based on data spanning 18 years, our study suggests that certain kinds of challenging jobs have the potential to enhance and protect workers’ mental functioning in later life.

The research analyzed data on 4,182 participants in the U-M Health and Retirement Study, which surveys a representative sample of more than 20,000 older Americans every two years.

Participants were interviewed about eight times between 1992 and 2010, starting when they were between the ages of 51 and 61. They worked in a wide variety of jobs and had been doing the same type of work for more than 25 years, on average, before they retired.

Fisher and colleagues examined the mental requirements of each job that participants reported having during that period. These requirements included analyzing data, developing objectives and strategies, making decisions, solving problems, evaluating information and thinking creatively.
They also assessed participants’ mental functioning, using standard tests of episodic memory and mental status. The tests included recalling a list of 10 nouns immediately after seeing it and also after a time delay, and counting backwards from 100 by sevens.

In addition, the researchers controlled for participants’ health, symptoms of depression, economic status and demographic characteristics, including years of education.

They found that people who had worked in jobs with greater mental demands were more likely to have better memories before they retired and more likely to have slower declines in memory after retiring than people who had worked in jobs with fewer mental demands.

The research has been published in the Journal of Occupational Health Psychology.
