Observed IAQ problems were strongly associated with increased worry and all symptoms under study (unadjusted ORs ranged between 1.48 [95% CI 1.48 2.16] and 2.70 [95% CI 1.52 - 5.17]). Parental worry was associated with all symptoms (unadjusted ORs ranged between 2.49 [95% CI 1.75 - 3.60] and 4.92 [95% CI 2.77- 9.40]). Mediation analyses suggested
that parental worry might partially explain the association between observed IAQ problems and symptom reporting (proportion mediated ranged between 67% and 84% for the different symptoms).
