Published in the Orthopaedic Journal of Sports Medicine, study of nearly 11,000 youth followed for 14 years 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, we did not find that," said study lead author Adam Bohr from University of Colorado Boulder.
The study analysed 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.
Participants were categorised into groups: those who, in 1994, said they intended to participate in contact sports; those who intended to play non-contact sports; and those who did not intend to play sports.
Among males, 26 per cent said they intended to play football.
After controlling for socioeconomic status, education, race and other factors, the researchers analysed scores through 2008 on word and number recall and questionnaires asking whether participants had been diagnosed with depression or attempted or thoughts 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.
Football players had a lower incidence of depression in early adulthood than other groups, said researchers.
According to them, those who reported that they did not intend to participate in sports during age 8 to 14 were 22 per cent more likely to suffer depression in their late 20s and 30s.
