The conclusion of the study was that “gambling advertising restrictions could reduce harm and lessen the impact of advertising on gambling-related inequalities”.
It stated: “Public health harm prevention strategies should include policies which limit exposure to advertising, particularly among children and vulnerable groups.”
On children and young people, it found “higher exposure to advertising is associated with higher gambling rates and severity".
James Grimes leads Gambling with Lives, which runs The Big Step campaign, calling for a ban on gambling advertising and sponsorship in football.
Mr Grimes said: “There’s now an abundance of evidence that clearly links advertising to addiction, as the millions of us harmed by gambling already know.
“The gambling industry spends £1.5bn a year on marketing - infecting our screens, our sports and our streets with a misleading representation of addictive gambling products.
