Abstract [en]

Background: Little is known on childhood exposure to air pollution and adult chronic respiratory outcomes.

Aim: To investigate associations between air pollution and greenness in childhood and adult lung health.

Methods: In selected centres of the RHINESSA study (age 18-52) we analysed the outcomes respiratory symptoms (≥3 symptoms), severe wheeze (wheeze last year with breathlessness, no cold) and late onset asthma (>10 years). We calculated mean annual exposures of PM2.5, PM10, NO2 (µg/m³) and greenness (Normalized Difference Vegetation Index, 100m buffer) from offspring's birth till age 18, categorised into mean exposure <10 years and 11-18 years. We performed multilevel logistic regression clustered by family, stratified by centre and adjusted for childhood passive smoke and parental asthma.

Results: 12% had ≥3 respiratory symptoms, 7.7% severe wheeze, and 9.4% late onset asthma. Overall estimates: greenness was associated with less respiratory symptoms, PM2.5 and NO2 with more late onset asthma. Exposure <10 years: Greenness was associated with less wheeze in Tartu (OR 0.29, 95%CI 0.11-0.73). PM2.5 (OR 1.22, 95%CI 1.00-1.48) and NO2 (OR 1.06, 95%CI 1.01-1.11) were risk factors for late onset asthma in Bergen. PM10 was a risk factor for respiratory symptoms (OR 1.21, 95%CI 1.04-1.41) in Uppsala and late onset asthma (OR 1.23, 95%CI 1.02-1.45) in Bergen. Exposure 11-18 years: Greenness was protective for respiratory symptoms (OR 0.29, 95%CI 0.10-0.86) and wheeze (OR 0.39, 95%CI 0.19-0.80) in Tartu.

Conclusions: Childhood exposure to greenness was associated with less respiratory symptoms, while air pollutants were associated with more respiratory symptoms (some centres) and late onset asthma.
