The retrospective phase analyzes anonymized data from more than 900 hypertensive patients collected between winter 2020 and spring 2021 in the Turin area. These mostly single-measurement clinical records are linked with pollution data from the same period to identify exposure–health associations and form the basis of an exposomic risk model.
The prospective phase will follow around 100 volunteers who consent to have their blood pressure measured twice (once in winter 2025 and once in spring 2026) via cuffed devices, allowing comparison of the same individuals under different seasonal pollution levels.
Together, the two phases provide complementary evidence on pollution-related health impacts and the potential of targeted indoor air quality interventions to support preventive healthcare strategies.
