- Abstract
Background: Phthalates can cause respiratory and immunological disorders. However, little is known about the role of serum periostin and YKL‐40 levels in mediating the effects of phthalates. We investigated the mediating role of these biomarkers in the relationship between phthalates and airway dysfunction. Methods: A total of 487 children (aged 10–12 years old) were examined. Four high‐molecular‐weight phthalate (HMWP) [Σ4HMWP] metabolites and 3 low‐molecular‐weight phthalate (LMWP) [Σ3LMWP] metabolites in urine samples were measured. Serum periostin and YKL‐40 levels were measured. Airway function was measured using impulse oscillometry. A mediation model was used to quantify the mediating effects of periostin and YKL‐40 on airway dysfunction. Results: After adjustment for height, gender, BMI z‐score, aeroallergen sensitization, secondary smoking, and vitamin D level, the level of urinary Σ3LMWP metabolites was significantly associated with respiratory system resistance at 5 Hz (Rrs5; adjusted β: 0.020, 95% CI: 0.005–0.034; p =.010). The levels of urinary Σ4HMWP and Σ3LMWP metabolites were significantly associated with periostin level, but not with YKL‐40 level. In addition, the periostin level was associated with Rrs5 (adjusted β: 0.048, 95% CI: 0.015–0.081; p =.005) and Rrs20‐5 (adjusted β: 0.040, 95% CI: 0.011–0.069; p =.007). Serum periostin level had a significant effect in mediating the relationship between Σ3LMWP and Rrs5 (13.9%, 95% CI: 10.7–77.0; p <.001). Conclusion: Exposure to LMWPs was significantly associated with airway dysfunction, and this effect was partially attributable to increased serum periostin level.
