Marchica and colleagues (2021) researched the health impact of an ‘emerging gambling activity’, with its growing support by adolescents. They noted esports betting, where players bet on the outcomes of organised video gaming competitions, had to date limited research on its relationship with youth mental health, and on problem gambling and problem video gaming. N=1,348 with a median age of 14.7 years, two-thirds being male, responded that n=263 (20%) had bet on esports over the past year.
