Note. Abbreviations: LAeq – equivalent daytime road traffic noise level. The models are adjusted for gender, age, nationality, income adequacy, population density, and university faculty. aThe index of moderated mediation represents the difference between conditional indirect effects.Effect estimates of LAeq are reported per 5 dB(A) increase. Coefficients are unstandardized linear regression coefficients (β) and odds ratios (OR) with their 95% confidence intervals (CI). The indirect effects were tested using the percentile bootstrap 95% CI (based on 5000 resamples).Statistically significant associations (P-value<0.05) are denoted by an asterisk (*).
