No Link Found Between Youth Contact Sports and Cognitive, Mental Health Problems

Adolescents who play contact sports, including football, are no more likely to experience cognitive impairment, depression or suicidal thoughts in early adulthood than their peers, suggests a new University of Colorado Boulder study of nearly 11,000 youth followed for 14 years.
The study, published this month in the Orthopaedic Journal of Sports Medicine, also found that those who play sports are less likely to suffer from mental health issues by their late 20s to early 30s.
"There is a common perception that there's a direct causal link between youth contact sports, head injuries and downstream adverse effects like impaired cognitive ability and mental health," said lead author Adam Bohr, Ph.D., a postdoctoral researcher in the Department of Integrative Physiology. "We did not find that."
The study comes on the heels of several highly-publicized papers linking sport-related concussion among former professional football players to chronic traumatic encephalopathy (CTE), cognitive decline and mental health issues later in life. Such reports have led many to question the safety of youth tackle football, and participation is declining nationally.
But few studies have looked specifically at adolescent participation in contact sports.
The study analyzed data from 10,951 participants in the National Longitudinal Study of Adolescent to Adult Health (Add Health), a representative sample of youth in seventh through 12th grades who have been interviewed and tested repeatedly since 1994.
"We were unable to find any meaningful difference between individuals who participated in contact sports and those who participated in non-contact sports. Across the board, across all measures, they looked more or less the same later in life," said Bohr.
Football players—for reasons that are not clear—actually had a lower incidence of depression in early adulthood than other groups.
