The HYENA (HYpertension and Exposure to Noise near Airports) study, a well-known study on the health effects of aircraft noise, involved 4,861 participants from six European countries (except France). The DEBATS (Discussion on the health effects of aircraft noise) study, a study with a similar protocol, included 1,244 participants from France. Associations were found between aircraft noise and cortisol levels in each study separately, but they were not consistent between the two studies. The objective of the present study was to combine both datasets in order to improve statistical power. We investigated the associations between aircraft noise levels and cortisol levels in the morning and in the evening, and the relative variation per hour, adjusted for relevant confounders. Analyses were carried out on the 1,300 participants with complete information for cortisol samplings and for confounders. We found evidence for an increase in the evening cortisol level in women (exp(ß)=1.09, 95%CI: 1.01;1.18), and for flattening of the relative variation per hour also in women (exp(ß)= 0.90, 95%CI: 0.840.97), with a Lden 10-dB(A) increase. There were no significant associations in men. These findings provide some support for a psychological stress induced by aircraft noise exposure, resulting in disruption of hormonal rhythms.
