Gambling-related harms can impact children living with parents experiencing a gambling problem. This study examined the impacts of parental gambling problems on the health and wellbeing of children. Specifically, the study explored whether harms to the health and wellbeing of children increase with more severe parental problem gambling. The researchers analyzed data from Growing up in Australia: The Longitudinal Study of Australian Children. The analysis examined responses from a total of 3,695 children across two cohorts aged 12 and 16 years. Around 49% of children were female. The researchers found that children whose parent(s) had some level of gambling problems had poorer health, more anxiety and/or lower mood symptoms, and more behavioural and emotional problems.
