Impact of transnational gentrification on the health of adults from the EPIPorto cohort: a quasi-experimental study

Living in gentrifying neighbourhoods in Porto, Northern Portugal, is linked to shorter nightly sleep duration by -0.346 h (95% CI -0.650 to -0.042) in adults from EPIPorto.

• Why it matters: Quantitative evidence on how neighbourhood gentrification affects population health is scarce and inconsistent, limiting evidence-informed urban policy in rapidly gentrifying cities.
• What they did: Using EPIPorto cohort data (1999–2022; 2,485 participants at baseline), neighbourhoods were classified as gentrifying vs non-gentrifying with a 16-variable transnational gentrification index from 2011–2021 census and tourism-accommodation data, then difference-in-differences models estimated effects on ten cardiometabolic and behavioural outcomes with inverse probability of censoring weighting.
• The result: Transnational gentrification showed no significant effects for BMI, overweight/obesity, cholesterol measures, blood pressure, or tobacco/alcohol use, but it was associated with reduced sleep duration, including in lower-education and ≥65-year subgroups.
