Gambling, geographical variations and deprivation: findings from the adult psychiatric morbidity survey

Gambling problems are prevalent in the UK, especially in the most deprived boroughs of the country. Individual-level characteristics may exist alongside a social and geographical gradient. The study aimed to establish whether living in specific geographic areas increases problem gambling likelihood. It used data from the 2007 Adult Psychiatric Morbidity Survey. It adopted a twofold categorization distinguishing recreational from problem/pathological gambling. It used the 2004 Overall Index of Multiple Deprivation to measure deprivation of the district of residence, and primary sampling units, based on postcode sectors, to take into account area characteristics in multi-level mixed-effects regression models. The determinants of recreational gambling operated solely at the individual level. These included male sex, stable relationship and employment, though a number of clinical variables were also important: impulsivity, hazardous use or dependency on alcohol, and current smoking. In contrast, an appreciable proportion of the variance in problem/pathological gambling was explained by area-level clustering. Unlike recreational gamblers, problem/pathological gamblers appear to cluster in specific areas. Thus, there are grounds for restricting the location and density of gambling opportunities and for providing selective prevention programmes targeting geographic areas characterized by contextual determinants
