This study reports the findings from a national survey on gambling behaviour among Danish primary school children. A questionnaire was administered to 2,223 primary school students ranging in age from 11 to 17 years. The questionnaire contained a gambling screen (SOGS-RA) and items that measure gambling behaviour, social network and cognitive perceptions. The prevalence of problem gambling was 1.29 per cent, while 4.5 per cent were categorised as at-risk gamblers. The three most frequently reported reasons for gambling were to win money, to have fun and to socialise with family and friends. It is suggested that gambling may be linked to a masculine universe and that at-risk gambling behaviour patterns may be part of a normal adolescent life in which gambling serves recreational or leisure purposes. Implications for further research and preventive measures are discussed.
