“…20,29,47,48 Our study adds to this literature by investigating such associations in a population of young children from low-income Values shown are regression coefficients (95% confidence intervals) for standardized environmental variables (rescaled, standard deviation=1); area characteristics are for neighborhood buffers, drawn as 0.5 km buffers around a line between the child's home and school; all models were adjusted for characteristics of the child (age, sex, and race/ethnicity), mother (age, born outside of the USA, use of Spanish, employed/student status), household (number of rooms), all of the neighborhood characteristics listed, and, for physical activity only, the total number of hours recorded as awake and the time of year; bold font is used to indicate statistical significance (p≤0.05); N=428 families. While previous studies have reported correlations between land use mix, 49,50 subway stop density, 51 safety, 21,24,25,27 vegetation, 30 or parks 31,32 with youth physical activity or adiposity, our results examine these associations in a highrisk urban subgroup with detailed outcome measurement using accelerometry and anthropometry. In this cohort of preschool-age children from low-income families in New York City, several measures of neighborhood composition, walkability, pedestrian safety, and greenness were correlated with physical activity or adiposity.…”
