Finding F-0279
“With an increase in formaldehyde by 10 ppb, AD symptom scores increased by 79.2% (95% CI, 19.6–168.4) in spring and by 39.9% (95% CI, 14.3–71.2) in summer when ambient PM2.5, temperature, and RH were controlled for.”
Structure
- Factor
- Formaldehyde (CH₂O)
- Outcome
- Atopic dermatitis symptoms
- Population
- children with moderate-to-severe atopic dermatitis
- Setting
- home, KR (summer)
- Study design
- longitudinal (panel) study of children with moderate-to-severe atopic dermatitis in Seoul: real-time indoor formaldehyde monitoring at home and daily symptom scores (4,789 person-days), generalized linear mixed models adjusted for ambient PM2.5, temperature and relative humidity (class 3)
- Effect
- difference 39.9 (14.3–71.2) per 10 %
- Caveat
- adjusted for ambient PM2.5, temperature and relative humidity
