Table 3 The joint effect of exposures t climate factors, traffic-related air pollution, and green spaces on the childhood respiratory system by quantile-based g-computation models.

From: Combined effects of traffic-related air pollution, climate factors, and greenness on respiratory disease risk in infants

Exposure variables

Joint effect

Adjusted odds ratio (95% CI)

PM2.5 + PMcrs + NO2

1.383 (1.325, 1.858)

Temperature + Humidity

1.472 (0.998, 1.472)

PM2.5 + PMcrs + NO2 + Temperature + Humidity

1.601 (1.021, 2.532)

PM2.5 + PMcrs + NO2 + Temperature + Humidity + NDVI

1.445 (0.836, 2.497)

  1. Note: Adjusted for maternal age, education, income, BMI, gestational age, exposure to secondhand smoke, birth weight, infant sex, and season of birth. CI, confidence interval; NDVI, Normalized Difference Vegetation Index; NO2, nitrogen dioxide; PM2.5, particulate matter with a diameter less than 2.5 μm; PMcrs, particulate matter with a diameter of 2.5 to 10 μm.
