[The gambling industry: a public health perspective.]

objectiveGambling may cause a variety of problems, both health and social, to the player, his family and his environment; Problems can be more serious for those who gamble more frequently or bet more money. Beyond the mental health gambling disorder and considering other harms derived from gambling, it is possible to develop a public health approach to the issue, including both prevention and harm reduction aspects. In recent decades gambling availability has expanded, with attempts at regulation. The objective of this paper is to provide basic information about gambling in Spain, stratifying data by Autonomous Communities (AC), from a public health perspective.

methodsA descriptive study of some aspects of gambling in Spain was carried out. The data for amounts gambled by participants, gross gaming revenue of the industry, and establishments or machines licensed for the year 2017 were extracted from the available systematic sources. Aggregated data were tabulated and stratified by AC for those presential gambling categories with the greatest compulsive gambling potential and relevant business volume. Crude results and ratios per 100,000 inhabitants were calculated.

resultsUp to 41,826.8 million euros were spent gambling throughout Spain in 2017, a figure that exceeds 3.5% of the Gross Domestic Product, and the largest segment was online gambling in its various modalities (32%), followed by the national lottery and similar traditional games (27%). The supply of gambling venues (74.9 establishments per million inhabitants) was assessed by AC, showing large differences among them: their density in the region of Murcia is tenfold that of Catalonia. Gambling machines that can be installed in hospitality establishments (B machines) showed a density of 43.4 per 1,000 inhabitants, with greater homogeneity across AC than gambling premises. Regional data on the amounts spent in casinos, bingo cards, and sports betting show no homogeneous patterns.

conclusionsThe volume of money spent on gambling in Spain is very important, and online gambling has become the largest business segment. The most traditional game modes and probably with less addictive potential such as lotteries and draws continue to have a relevant presence. The availability of presential gambling shows wide heterogeneity among AC, especially for licensed gambling establishments, whose density is ten times greater in the community with more supply compared to the one with less. The data by AC of some game modalities suggest that availability may be a relevant factor for gambling, but not the only one.
