For men experiencing emotional distress like depression, anxiety or thoughts of suicide, having high cardiorespiratory fitness may cut the risk of death in half compared to those in poor condition, researchers say.
“The prevalence of mental health issues is growing in the U.S. and globally,” said lead study author Mei Sui of the University of South Carolina in Columbia. “People are facing many stressors in their daily lives linked to depression, anxiety and other mental disorders.
Mental health conditions cost the U.S. about $2.5 trillion in 2010 and are projected to cost the country $6 trillion by 2030, the authors write in Mayo Clinic Proceedings.
To see how cardiovascular fitness might affect healthcare costs and outcomes for people with mental health disorders, Sui and colleagues analyzed data from the Aerobics Center Longitudinal Study at the Cooper Clinic in Dallas, Texas, which conducted preventive health exams on more than 43,000 men between 1987 and 2002.
The researchers focused on 5,240 participants who reported a history of emotional distress, including 2,229 who reported more than one emotional distress condition. To measure cardiorespiratory fitness, participants ran on a treadmill until they were exhausted.
Among men who experienced emotional distress, 46 percent reported depression, 58 percent had anxiety, 51 percent had a history of mental counseling, and 8 percent reported ever having thoughts of suicide.
The researchers found that men with the lowest cardiovascular fitness tended to have higher weight, blood pressure, cholesterol and blood sugar levels and were more likely to smoke and to be sedentary.
Compared to the lowest-fitness group, men with moderate cardiovascular fitness were 46 percent less likely to die of any cause during the study, and those in the high fitness group were 53 percent less likely to die.
