Teens in Contact Sports May Not Be at Greater Risk for Future Cognitive, Mental Health Issues

Youth who play contact sports, including football, appear no more likely to experience cognitive dysfunction, depression or suicidal thoughts in early adulthood than their peers who don’t play contact sports, according to a new study at the University of Colorado (CU) Boulder.

“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 research, which followed nearly 11,000 adolescents for 14 years, also found that adolescents who play sports are less likely to suffer from mental health issues by their late 20s to early 30s.

The study, recently published in the Orthopaedic Journal of Sports Medicine, 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.

Still, there is little research focused specifically on adolescent participation in contact sports.

“When people talk about NFL players, they are talking about an elite subset of the population,” said senior author Dr. Matthew McQueen, an associate professor of integrative physiology. “We wanted to look specifically at kids and determine if there are true harms that are showing up early in adulthood.”

The researchers looked at 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 were interviewed and tested repeatedly since 1994.

Participants were categorized into groups: teens who, in 1994, said they intended to participate in contact sports; teens who intended to play non-contact sports; and those who did not intend to play sports. Among males, 26% said they intended to play football.

After controlling for socioeconomic status, education, race and other factors, the researchers analyzed scores through 2008 on word and number recall and questionnaires asking whether participants had been diagnosed with depression or attempted or thought about suicide.

“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.

In fact, for some reason football players actually had a lower incidence of depression in early adulthood than other groups.

Teens who reported they did not intend to participate in sports at age 8 to 14 were 22% more likely to suffer depression in their late 20s and 30s.

“Right now, football is in many ways being compared to cigarette smoking — no benefit and all harm,” said McQueen, who is also director for the Pac-12 Concussion Coordinating Unit. “It is absolutely true that there is a subset of NFL players who have experienced horrible neurological decline, and we need to continue to research to improve our understanding of that important issue.”

But, he said, “the idea that playing football in high school will lead to similar outcomes later in life as those who played in the NFL is not consistent with the evidence. In fact, we and others have found there is some benefit to playing youth sports.”

A recent University of Pennsylvania study of 3,000 men who had graduated high school in Wisconsin in 1957 found that those who played football were no more likely to suffer depression or cognitive impairment later. But some pointed out that the sport had changed radically since the 1950s.

The new study is among the largest to date and looks at those who played football in the 1990s.

The authors note that, due to the design of the dataset, they were only able to measure “intended” participation. (Due to the timing of the questionnaires, however, it is likely that those who reported participation in football actually did participate.)

The researchers also could not tell how long an adolescent played, what position or whether a concussion or sub-concussive head injury was ever sustained. Further studies should be done exploring those factors, they said.

“Few current public health issues are as contentious and controversial as the safety and consequences of participation in football,” they concluded. “Research on the risks of participation weighed with the risks of not participating in sports will enable parents and young athletes to make educated, informed decisions based on solid evidence.”

A new CU Boulder study, looking at the long-term mental and physical health of CU student-athlete alumni, is currently in progress.
