The Swedish Longitudinal Gambling Study (Swelogs) is one of the world's largest long-term population studies which examines the relationship between gambling for money and health.
The aim of the study is to obtain up-to-date knowledge of gambling in Sweden which may form the basis for the development of preventative methods. The study includes describing gambling in Sweden, studying the prevalence and incidence of gambling problems and showing changes over time. In addition to this, gambling is studied in relation to other lifestyle issues such as alcohol consumption, tobacco use, general health, safety and social relations, employment, economy and housing.
In 2008 Swelogs started a national sample of 15,000 randomly selected persons in the age group 16–84 years. Approximately 8,000 persons participated in the survey and since then they have been contacted three more times. The fourth and last interview round was conducted in 2014. Swelogs also includes an in-depth study, with roughly 2,000 persons from the population study, which examines risk and protective factors for gambling problems.
In 2015 a new sample of 21,000 persons aged 16–84 years was selected. Approximately 9,400 persons in this new cohort responded.
The factsheets describe fundamental facts on different gambling forms in the Swedish market. Each factsheet presents the proportion of the population that uses the gambling form, which population groups gamble, the health of the gamblers and the proportion with gambling problems.
