The Finnish gambling system is based on a state monopoly, regulated by the Lotteries Act. After an amendment to the Lotteries Act, the new minimum legal gambling age was raised to 18\u00a0years old between 2010 and 2011. The main purpose of this study was to discover how the amendment to the act altered adolescents\u2019 gambling (14\u201316-year-olds) and to examine whether the amendment decreased socio-economic differences. Adolescents gambling was studied before (2008\u20132009), during (2010\u20132011), and after (2013\u20132017) the age limit of gambling was raised in Finland. The study based on five waves (2008\u20132009, 2010\u20132011, 2013, 2015, 2017) of the national repeated cross-sectional School Health Promotion Study. Cross-tabulations where gambling was studied by study year and socio-economic status (SES) were formulated, and the statistical differences were studied by using \u03c7<jats:sup>2<\/jats:sup>-tests. Percentage change in gambling frequency was also examined by study year and SES. Study years were analyzed separately to model the weekly gambling via logistic regression models. Adolescent gambling significantly decreased over time. It appears that raising the legal gambling age had a permanent effect on under-aged gambling. However, differences in gambling by adolescents\u2019 family\u2019s SES increased during the study period, indicating widening inequalities in gambling among adolescents. Diminishing inequalities in adolescent gambling is likely to require both societal action and consensus on adolescent gambling being a significant social and public health concern.<\/jats:p>","DOI":"10.1007\/s10899-021-10091-6","type":"journal-article","created":{"date-parts":[[2021,12,7]],"date-time":"2021-12-07T16:04:45Z","timestamp":1638893085000},"page":"1243-1256","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Gambling Among Finnish 14\u201316-Year-Old Adolescents Before (2008\u20132009), During (2010\u20132011), and After (2013\u20132017) Setting the Legal Age Limit of 18 for Gambling and the Role of Socio-Economic Status"],"prefix":"10.1007","volume":"38","author":[{"given":"Tiina","family":"Latvala","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomi","family":"Lintonen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pauliina","family":"Luopa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susanna","family":"Raisamo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,12,7]]},"reference":[{"issue":"12","key":"10091_CR1","doi-asserted-by":"publisher","first-page":"2176","DOI":"10.1111\/j.1360-0443.2010.03100.x","volume":"105","author":"N Auger","year":"2010","unstructured":"Auger, N., Lo, E., Cantinotti, M., & O\u2019Loughlin, J.
