This study analyzes the data collected during audits of the housing of Parisian patients to highlight links between elements in the habitat and a diagnosis of interstitial lung disease (ILD). An exploratory case-control study was performed with data from 122 patients interviewed from 2011 to 2017: 47 patients had ILD, 75 control patients had extrapulmonary conditions. The diagnosis of ILD was significantly correlated with four of the 14 factors examined (by measurement data and questionnaires): presence of plants in the dwelling (odds ratio (OR) = 4.14; 95% CI = [1.45;11.81]), presence of pigeons near the home (OR = 3.9; 95% IC = [1.56;9.76]), presence of Penicillium spp in the samples (air, dust, or surfaces) (OR = 3.33; 95% IC = [1.41;7.88]), and housing occupancy > 10 years (OR = 3.06; 95% IC = [1.34;6.98]). The on-site audit identified risk factors present in the habitat that could affect the health of the occupants possibly requiring eviction measures.
