Note: There were no interactions with site
All models were adjusted for gender, age, education, ethnicity, # motor vehicles/adult in household, site, marital status, number of people in household, and length of time at current address. 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.
