Childhood gambling linked to adult problem gambling risk in Ireland

Summary

A new ESRI Research Bulletin, based on an anonymous online survey of 1,663 adults, finds that exposure to gambling in childhood significantly raises the likelihood of experiencing gambling harm in adulthood. The study used the Problem Gambling Severity Index (PGSI) to measure adult gambling harm and asked about respondents’ gambling before age 18, parental gambling frequency and parental attitudes.

Those who gambled as children were nearly twice as likely to meet PGSI criteria for problem gambling later in life. Parental gambling increased the risk by roughly one-third, while heavy parental gambling almost doubled it. When childhood gambling and heavy parental gambling combined, the study found about a fourfold increase in adult problem-gambling risk. The research also notes generational differences: among those under 40 the parental link is weaker, likely reflecting greater exposure via online platforms and marketing. The Gambling Regulatory Authority of Ireland (GRAI) funded the research and recommends stronger age verification, tighter marketing controls and regulation of child-appealing products, alongside efforts to reduce harmful parental gambling.

Key Points

Almost 64% of respondents reported gambling before age 18; common activities included slot machines, scratch cards, race betting, informal bets among friends, bingo and lotteries.
Childhood gambling nearly doubled the odds of adult problem gambling as measured by the PGSI.
Having a parent who gambled raised adult risk by about one-third; heavy parental gambling almost doubled the risk.
Individuals who gambled before 18 and had a parent who gambled heavily faced around a fourfold increase in adult problem-gambling risk.
Generational shift: parental influence on later harm is weaker for under-40s, suggesting online exposure and marketing are now important vectors.
Certain childhood activities (sports betting, casino-style games, loot boxes) were associated with higher later risk, though their childhood prevalence was relatively low in the survey.
Policy recommendations include stronger age checks, tighter controls on gambling marketing, regulation of child-appealing products and targeted support/education for parents.

Why should I read this?

Short and blunt: if you care about protecting kids or shaping gambling policy, this study shows how early exposure and parental behaviour stack the odds for later harm. Read this to get the bits that matter without wading through the full bulletin.

Context and relevance

The findings add to growing international evidence that early gambling exposure and parental gambling behaviour are key drivers of later harm. For regulators, industry compliance teams and child-welfare groups the research is timely: it supports tighter age-verification and marketing rules and highlights the need to tackle online exposure. The weaker parental effect in younger cohorts signals that interventions must also prioritise advertising, platform design and products that appeal to children.
