Body Mass Index, minutes spent in a car, kilometers walked, age, income, educational attainment, and gender were derived through a travel survey of 10,878 participants in the Atlanta, Georgia region. Objective measures of land use mix, net residential density, and street connectivity were developed within a 1-kilometer network distance of each partici-pant’s place of residence. A cross-sectional design was used to associate urban form measures with obesity, BMI, and transportation-related activity when adjusting for socio-demographic covariates. Discrete analyses were conducted across gender and ethnicity.The data were collected between 2000 and 2002 and analysis was conducted in 2004.
