The prevalence of common diseases in Helsinki fell by 10 per cent between 2019 and 2025, with residents recording lower levels of illness than Finland as a whole, according to data published by the City of Helsinki. Differences between parts of the capital remain substantial despite the overall decline.
The reduction was driven in particular by declines in hypertension and coronary heart disease, the city said in a research review based on data from the Social Insurance Institution of Finland, Kela, and Statistics Finland.
