Associations Between Built Environment Factors and SARS-CoV-2 Infections at the Neighbourhood Level in a Metropolitan Area in Germany

This study examined the association between built environment factors and SARS-CoV-2 infections in a metropolitan area in Germany. Polymerase chain reaction (PCR)-confirmed SARS-CoV-2 infections of 7866 citizens of Essen between March 2020 and May 2021 were analysed, aggregated at the neighbourhood level. We performed spatial regression analyses to investigate associations between the cumulative number of SARS-CoV-2 infections per 1000 inhabitants (cum. SARS-CoV-2 infections) up to 31.05.2021 and built environment factors. The cum. SARS-CoV-2 infections in neighbourhoods (median: 11.5, IQR: 8.1 –16.9) followed a marked socially determined north–south gradient. The effect estimates of the adjusted spatial regression models showed negative associations with urban greenness, i.e. normalized difference vegetation index (NDVI) (adjustedβ =  − 35.36, 95% CI: − 57.68; − 13.04), rooms per person (− 10.40, − 13.79; − 7.01), living space per person (− 0.51, − 0.66; − 0.36), and residential (− 0.07, 0.16; 0.01) and commercial areas (− 0.15, − 0.25; − 0.05). Residen tial areas with multi-storey buildings (− 0.03, − 0.12; 0.06) and green space (0.03, − 0.05; 0.11) did not show a substantial association. Our results suggest that the built environment matters for the spread of SARS-CoV-2 infections, such as more spacious apartments or higher levels of urban greenness are associated with lower infe...
