Summary

This completed study looked at how the COVID-19 pandemic affected online gambling in France and Sweden, using data from 120,000 gamblers. Researchers compared gambling behaviors before and during the pandemic, including money spent and types of games played. They also examined differences between countries with strict lockdowns (France) and those without (Sweden), as well as differences between men and women. The goal was to identify risky gambling patterns and inform public health responses.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this research could help public health authorities understand how crises like a pandemic affect gambling habits, potentially guiding future prevention strategies.
What could go wrong
This is an observational study using existing data, so it cannot prove cause and effect. Results may not apply to other countries or future pandemics.
