A large-scale study conducted in Germany provides concrete evidence of something public health specialists have been warning about for years: gambling advertising does not affect all players equally. Those who already have gambling problems are significantly more susceptible to modifying their attitudes and behaviors after exposure to industry advertisements.

Methodology: nearly 4,800 active players under the microscope
The **Germany** study surveyed 4,800 active players between 18 and 70 years old, with an average age of 47, of whom 57% of participants identified as male. The fieldwork was conducted during the summer of 2021, and participants were recruited through an online panel.
The research analyzed three dimensions of advertising impact reported by the respondents themselves: the effects on their attitudes, interests, and behaviors linked to gambling; the level of awareness of industry advertising; and the understanding of the different types of gambling and providers available.
To classify participants according to their level of vulnerability, the study used the criteria of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), grouping them into three categories: non-problem gamblers (0 criteria met), at-risk gamblers (between 1 and 3 criteria), and gamblers with a gambling disorder (4 or more criteria).
The central finding: advertising impacts those who are already vulnerable the most
In the three dimensions analyzed, participants classified with a gambling disorder reported more frequently that advertising affected them, compared to those without problems. The strongest association was found in the “participation” dimension, which measures concrete changes in attitudes or behaviors related to betting.
The most eloquent data point from the study is as follows: 36.5% of vulnerable players stated that they tend to gamble after seeing gambling advertisements. Among non-problem gamblers, that figure dropped to 8%. The gap is revealing and difficult to ignore from a regulatory perspective.

Multivariate statistical models, which controlled for variables such as age and sex, confirmed that higher scores in the participation dimension were the strongest predictors of gambling problems. Each increase in that category multiplied the probability of presenting some DSM-5 symptom by 3.8, and the probability of developing a consolidated gambling disorder by 4.8.
Young men: the highest risk profile
Beyond the effect of advertising, the study identified demographic variables that, on their own, increase the probability of developing gambling problems. Men showed an approximately 1.4 times higher probability of presenting some symptom of problem gambling, and between 1.7 and 1.8 times higher probability of developing an established disorder, compared to women.
Age also proved to be a determining factor, but in the opposite direction: the older the age, the lower the probability of suffering harm derived from gambling. This places young men as the highest-risk demographic group and reinforces the need for prevention policies that target them as a priority.
The channel matters: internet and social networks, the most concerning
Although the study did not break down the results by specific advertising platform, the authors cited previous research suggesting important differences depending on the channel. Advertising on the internet and social networks appeared particularly linked to the participation dimension, that is, to effective behavior change. Television, on the other hand, showed a greater relationship with awareness and general knowledge about gambling, without necessarily translating into an immediate urge to bet.
This distinction has direct implications for the design of advertising regulations: not all media generate the same type of impact, and restrictions should take these differences into account.
