Lesbian, gay, and bisexual (LGB) individuals show higher risks for problem gambling, suicide, substance use, and obsessive-compulsive personality disorder traits compared to heterosexual individuals. Further research is needed to confirm these findings in clinical populations.
Area of Science:
- Public Health
- Psychiatry
- Neuropsychology
Background:
- Gambling is a prevalent behavior with significant public health implications.
- Limited research exists on gambling patterns within sexual minority populations.
- Understanding differences in gambling among lesbian, gay, and bisexual (LGB) individuals compared to heterosexual individuals is crucial.
Purpose of the Study:
- To investigate potential differences in gambling behaviors and associated characteristics between LGB and non-LGB individuals.
- To explore the relationship between sexual orientation and problem gambling, mental health, and cognitive function.
Main Methods:
- A cohort of 534 young adults (18-29 years) who gambled at least 5 times in the past year were assessed.
- Participants underwent clinical and neurocognitive evaluations.
- LGB individuals were compared to heterosexual individuals on various measures.
Main Results:
- 9.6% of participants identified as LGB.
- LGB individuals reported significantly higher rates of problem gambling.
- Elevated risks for suicide, substance use disorders, obsessive-compulsive personality disorder traits, and cognitive differences were observed in LGB individuals.
Conclusions:
- Individuals with minority sexual orientations may face heightened risks for problem gambling and related issues, including suicidality and obsessive-compulsive personality disorder traits.
- Cognitive differences were noted in LGB individuals, warranting further investigation.
- Future research should focus on clinical samples and large-scale longitudinal studies in diverse populations.

Testing a Claim about Population Proportion
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...
