Health-related quality of life 1 year after a large-scale industrial fire among exposed inhabitants of Rouen, France: 'The Post Fire 76 Health' study.

Background A large-scale industrial fire occurred in Rouen, France, in 2019. This study assessed the health-related quality of life of people exposed to its consequences 1 year later. Methods The study population comprised inhabitants of the exposed area and a non-exposed area. A representative sample was randomly selected using a stratified design. Data were collected using a standardized questionnaire to describe fire exposure and to calculate three health-related quality of life scores according to the SF12-v2 scale. After adjustment, descriptive and multivariate analyses were conducted. Results The sample comprised 4773 participants (response rate 47.7%). In the exposed area, the average mental, physical and overall health scores were 47.5, 52.0 and 73.8 out of 100, respectively. Mean mental and overall health scores were higher in the non-exposed area (49.0 and 76.0, respectively). After adjustment, a lower mental health score was associated with a higher number of perceived types of exposure, reaching −3.72 points [−5.41; −2.04] for five or more different types of perceived exposure. A lower mental health score was associated with soot deposits (−1.04 [−1.70; −0.39]), perceiving odours [(−2.04 [−3.22; −0.86]) up to the day of data collection], and having seen, heard or been awakened by the fire (−1.21 [−1.90; −0.52]). A slightly lower physical health score was associated with soot deposits (−0.57 [−1.07; −0.08]). Conclusion This study highlighted associations between exposure to the consequences of the industrial fire in Rouen and a deterioration of perceived health-related quality of life 1 year later, particularly the mental health dimension.
