How can the country that taught its kids to quit everything take more antidepressants than anyone in the OECD?

The teen turnaround

• The programme is called the Icelandic Prevention Model, started around 1999, now exported as Planet Youth. It began with parents, schools and the city, not with a campaign aimed at kids.

What they actually did

Lever	Fact
The clock	Child Protection Act: age 12 and under home by 8pm. Age 13 to 16 home by 10pm in winter (1 Sept to 1 May), midnight in summer. CONFIDENT https://reykjavik.is/en/curfew
The card	Reykjavik gives every child aged 6 to 18 a leisure card worth 75,000 ISK a year (since 01/01/2023), only usable on sports, music, clubs. CONFIDENT https://reykjavik.is/en/recreation-card
The data	Every school surveyed every year, results returned to each neighbourhood within months. This is the part other countries skip.

The three lenses (the part nobody posts about)

Diet. Soft and energy drink consumption is "by far the highest" in the Nordics. Children drink them 3.1 times a week. Fruit and vegetable intake is the lowest in the Nordics, sweets and biscuits among the highest. Fish is the bright spot: Icelandic kids eat more fish than any other Nordic kids. (Nordic Monitoring 2024, published 12/2025, CONFIDENT) https://island.is/en/news/nordic-monitoring-of-diet-physical-activity-physique-and-alcohol-and-tobacco

Social norms. Adult obesity went from 21% in 2014 to 28% in 2024, the highest in the Nordics. About 6% of children have obesity, vs 2 to 5.5% in the other Nordic countries. Icelanders walk and cycle the least in the Nordics, about 2 hours a week: it is a car country. Yet Icelandic children are the most physically active in the Nordics, which is the leisure card showing up in the data. (Same source, CONFIDENT)

Headline numbers

• Teens and caffeine: survey of 10,358 Icelandic 13 to 15 year olds (about 80% of the age group). Among energy drink users, 31 to 38% were over the caffeine level that affects sleep, vs 5 to 8% of non-users. Teens sleeping 6 hours or less went from 3% at low caffeine to 24% at high. (Halldorsson et al. 2021, Food and Chemical Toxicology, CONFIDENT abstract) https://pubmed.ncbi.nlm.nih.gov/34509583/
• E-cigarette use and nicotine pouches: higher in Iceland than the other Nordics and rising (Nordic Monitoring 2024, CONFIDENT, no number given).

The honest story

Iceland did not make teenagers healthy. It removed alcohol, tobacco and cannabis from their lives with structure. What filled the gap was energy drinks, nicotine pouches and vapes, and the adults around them got heavier the whole time. That is a better episode than "Iceland fixed it", and it is true.
