Residential green space and pathways to term birth weight in the Canadian Healthy Infant Longitudinal Development (CHILD) Study

Table 2 Changes in term birth weight associated with a 0.1 IQR increase in residential NDVI during pregnancy

NDVI Buffer	Model 1 β (95% CI)	Model 2 β (95% CI)	Model 3 β (95% CI)
100 m	14.1 (− 5.4, 33.7)	3.9 (− 17.4, 25.2)	4.0 (− 18.1, 26.1)
250 m	16.5 (− 4.6, 37.6)	11.6 (− 11.4, 34.6)	12.7 (− 11.6, 36.9)
500 m	18.8 (− 3.4, 41.1)	18.3 (− 6.1, 42.7)	21.5 (− 4.6, 47.7)
1000 m	15.7 (− 7.2, 38.7)	14.4 (− 10.8, 39.5)	17.8 (− 9.5, 45.0)

Model 1: Unadjusted model includes gestational age
Model 2: Model 1 plus individual characteristics: baby’s sex, year and month of birth, mother’s age, mothers smoking during pregnancy, mother/father education, mother/father race/ethnicity, household income, indoor air quality index and city
Model 3: Model 2 plus neighborhood household income, % without high school education, unemployment, % minority and population density at 1 km
