OBJECTIVE: The study presents the immediate post-intervention results of Kids and Adults Now Defeat Obesity!, a randomized controlled trial to enhance healthy lifestyle behaviors in mother-preschooler (2 to 5 years old) dyads in North Carolina (2007 to 2011). The outcomes include change from baseline in the child's diet, physical activity and weight, and in the mother's parenting behaviors, diet, physical activity, and weight. METHOD: The intervention targeted parenting through maternal emotion regulation, home environment, feeding practices, and modeling of healthy behaviors. 400 mother-child dyads were randomized. RESULTS: Mothers in the intervention arm, compared to the control arm, reduced instrumental feeding (-0.24 versus 0.01, p < 0.001) and TV snacks (-0.069 versus -0.24, p = 0.001). There were also improvements in emotional feeding (p = 0.03), mother's sugary beverage (p = 0.03) and fruit/vegetable (p = 0.04) intake, and dinners eaten in front of TV (p = 0.01); these differences were not significant after adjustment for multiple comparisons. CONCLUSION: KAN-DO, designed to maximize the capacity of mothers as agents of change, improved several channels of maternal influence. There were no group differences in the primary outcomes, but differences were observed in the parenting and maternal outcomes and there were trends toward improvement in the preschoolers' diets. Long-term follow-up will address whether these short-term trends ultimately improve weight status.
