All models were adjusted for gender, age, education, ethnicity, # motor vehicles/adult in household, site, marital status, number of people in household, length of time at current address, and reasons for moving here. In addition, neighborhood clustering was adjusted for in all models. For MVPA, the IPAQ variables, BMI and overweight/obesity status, time was adjusted for to account for repeated measures.
