In the analyses for thirteen pollutants (outdoor components and indoor components) of the ECQI, distance from the factory (<=500 m) and distance from the chimney (<=500 m) were positively associated with the risk of asthma, eczema, and rhinitis. The risk of housing along the street and rhinitis was 1.47 (95% CI; 1.02-2.12), and the risk between polluting heating fuel and asthma was 2.34 (95% CI; 1.12-4.88). Our results showed that compared with a low ECQI score, a positive relationship among the risk of asthma and allergy, increasing with the accumulation of indoor and outdoor risk factors.
