Constant: preschool (reference groups); Age2: elementary; Age3: middle school
P-BMI: mean-centered parental BMI; C-BMI: child percent of 95th BMI percentile (%BMIp95)
Behaviors: FV (fruit and vegetable intake [times per day]), SSB (sugar-sweetened beverage intake [times per day]), screen time (TV, DVD, computer, video game [hours per week]), and PA (physical activity [7 days/week vs. < 7 days/week]) of child
