This objective of this report was to examine patterns of weight gain in children from age 3 to 12 years based on the extent to which they exhibited self-regulation in a self-control procedure at age 3 years and a delay of gratification procedure at age 5 years. The findings show that indeed children who exhibited low self-regulation in both procedures had significantly higher BMI at all points. In addition, children who exhibited low self-regulation in both procedures had the most rapid gains in BMI from age 3 to 12 years. These findings advance the literature on childhood obesity in at least 2 important ways. First, early childhood self-regulatory problems are important longitudinal predictors of weight problems in early adolescence. Second, self-regulation failure in the behavioral procedures appears to generalize to regulatory problems in the energy-balance domain of development, as evidenced by higher weight status and more rapid weight gain from early childhood through adolescence. While the delay of gratification procedure measured the ability to delay immediate gratification for a larger food reward, this procedure was not intended to measure energy-balance regulation. There is a specific behavioral protocol that measures eating (or overeating) in the absence of hunger, which is a more accurate indicator of self-regulation failure in the energy-balance domain.24,25 We are limited by the fact that there were no steps taken to standardize children's hunger level before the delay of gratification procedure, so the extent to which hunger played a role in children's decision to choose an immediate reward is unclear.
