A couple of weeks ago I wrote a blog on why problem gambling should be considered a health issue. Earlier this week, I came across an interesting study carried out by jackpot.co.uk who surveyed 2,131 online gamblers (58% males and 42% female) about their health. After the self-reported data had been collected, the gamblers were classed into one of nine categories based on the casino game type that the gambler played most often (i.e., slot machines, video poker, blackjack, roulette, dice/craps, baccarat, poker, pai gow, and ‘other’). The data were then tabulated so that all the health variables (including obesity) corresponded to the gambler’s preferred casino game.
I was interested in the findings not only because I am a Professor of Gambling Studies, but also because I was a member of the Department of Health’s ‘Expert Working Group on Sedentary Behaviour, Screen Time and Obesity’ (a reference to our final report to the British government can be found in the ‘Further Reading’ section below). The study took an objective measurement of physical condition by asking each gambler their height (centimetres) and their weight (kilograms) to calculate each person’s Body Mass Index (BMI) by dividing the gamblers’ weight by height (metres) and dividing by height again (for example, someone who weighs 80kg and is 180cm tall, the BMI is 24.1 as this is 80/1.80)/1.80). The survey then asked s few general health and lifestyle questions (similar to ones that we have used in the last few British Gambling Prevalence Surveys:
- Do you normally drink more than the recommended limit for weekly alcohol consumption (21 units of alcohol for men and 14 for women)? (Yes/No)
- Do you smoke regularly? (Yes/No)
- Do you normally engage in at least 30 minutes of physical activity, 5 times per week? (Yes/No)
Overall, the survey found that British casino gamblers as a group were no less healthy than the rest of the British population, with an average Body Mass index (BMI) of 27 (which is the same as the UK national average). However, the survey also reported that the average BMIs, health, and lifestyle choices (such as smoking cigarettes, engaging in exercise, and drinking alcohol varied considerably depending on the casino games that the respondents played. Here are some of the main findings:
- Slots players were the least healthy. They took less exercise and had an average BMI of 31, pushing them into the category of obese (which is linked to increased chance of developing illnesses such as Type 2 diabetes and reduced life expectancy)
- Roulette, blackjack, video poker and craps/dice players were not far behind slots players, each having BMI levels higher than the national average.
- Those that played poker, baccarat and Pai Gow had an average BMI of 25 or under (well within the normal range recommended by the World Health Organisation.
- Whilst drinking levels might be reasonably high among poker players, they were very exercise conscious, with 58% engaging in physical activity for at least 30 minutes, five times a week. For slots players the figure was 27% meeting this government recommended target.
- Overall slots players drink the most, with 24.1% drinking over the recommended weekly limit. Poker players are not far behind on 23%. Female slots players were the biggest drinking subgroup, closely followed by male poker players.
- Slots players also smoked more, with 24% being regular smokers (compared to the UK national average of 20%). Blackjack and roulette players smoked slightly more than average, on 21% and 22% respectively, while poker players smoked slightly less than average, on 19.5%.
None of these results is overly surprising as there are many studies (including my own) showing comorbidity between gambling and other potentially addictive behaviours. However, very few academic studies have ever looked at these health variables by game type. Although this was not an academic study, the results will likely be of interest to those in the gambling studies field.
The survey also examined the most common platform on which the gamblers played casino games. The most common was the desktop computer (65%), followed by mobiles and tablets (20%) and land-based casinos (14%). This is not surprising given the survey was completed by online gamblers. Interestingly, desktop use was linked to higher levels of obesity, drinking and smoking. This is something that I would expect given that online gambling is the most sedentary of these activities.
There are (of course) some limitations with the data collected particularly as it comprised a self-selected sample of online gamblers that played via jackpot.co.uk websites. We have no idea as to whether the sample is representative of all online gamblers but as I noted above, it is no surprise that online gamblers preferred playing casino games online compared to offline (i.e., land-based casinos). The data were also self-report and are therefore open to any number of individual biases including recall biases and social desirability biases. Also, we have no geographical breakdown of the sample as the internet (by definition) is global. However, the sample size is good in comparison to many published studies on gambling and the sample included individuals that were actually gamblers (as opposed to university undergraduates or members of the general public). According to Sam Marsden (editor of jackpot.co.uk and author of the report):
“There’s an undeniable link connecting passive games like slots and video poker to unhealthy, sedentary lifestyles. On the other hand, games that require concentration, strategy and some physical stamina like poker and blackjack seem to fare much better in the health stakes. It seems it’s less a case of ‘you are what you eat’ and more ‘you are what you play’.”
Although such a conclusion could be argued to be PR spin on the findings, the results suggest that more rigorous studies could be carried out in the area including secondary analyses of the robust datasets that already exist including the British Gambling Prevalence Surveys, the English Health Surveys, and the Scottish health Surveys.
