Unemployment may up the risk of death in people but recession could help cut mortality risk, reveals new research.
Researchers from Drexel University and the University of Michigan in Ann Arbor revealed that job loss was associated with a 73 percent increase in the probability of death, the equivalent of adding 10 years to a person's age. However, this increased risk affected only the minority of people who were unemployed and was outweighed by health-promoting effects of an economic slowdown that affect the entire population, such as a drop in traffic fatalities and reduced atmospheric pollution.
The researchers found that each percentage-point increased in the individual's state unemployment rate reduced the hazard of death by approximately 9 percent, which was about the equivalent of making a person one year younger.
Jose Tapia, PhD, said that most people believed that being unemployed was a bad thing but what many people don't realize was that economic expansions, which usually reduces joblessness also have effects that could be harmful for society at large.
While this investigation did not cover the potential causes for these phenomena, the researchers suggested that the increase in the risk of death associated with individual joblessness might be related to stress and depression, which often lead to substance abuse and other harmful behaviors. Atmospheric pollution, which strongly increases in economic upturns and diminishes in recession, might be one of several important mechanisms explaining why population mortality tends to decrease when the economy stagnates.
