Methods

In this project we will rely on data from two large population-based cohorts from Porto Metropolitan Area:

Geração XXI 

+

EPIPorto

Because participants’ locations are geocoded, neighbourhood-level measures can be integrated with the information about the physical and mental health of the two ongoing cohort studies.

We will measure gentrification, housing insecurity and displacement at neighbourhood-level over the last two decades using mixed data sources from the questionnaires, censuses, commercial and administrative databases and novel statistical methods.

Based on these longitudinal datasets, and using the current neighbourhood change processes as a natural experiment, we will fit mixed-effects regression models to compare the same individual’s health before and after neighbourhood change.

This strong quantitative approach will be seasoned with a community-based participatory qualitative study, which will convey depth to our analysis and empower citizens. For that, we will conduct semi-structured interviews and a Photovoice study in a sample of cohort participants to capture their experiences and opinions about the health, social and community consequences of current neighbourhood change processes.
