Although multicomponent behavioral interventions for parents of young children with T1D demonstrate potentially promising psychosocial outcomes [8-10], concomitant improvements in children's glycemic control from these interventions remain elusive. Two critical areas not yet addressed directly in interventions is the promotion of healthy eating and engagement in consistent physical activity in young children, nor the behavioral strategies to support parents in these challenges that occur multiple times daily (e.g., each meal/snack, each physical activity experience). The current proposal utilizes the extensive expertise of our multidisciplinary team to refine and pilot an innovative and translatable intervention targeting eating and physical activity behaviors directly associated with glycemic control in young children that can ultimately be adopted outside of research settings. The investigators' prior successful clinical research efforts engaging parents of young children with T1D in behavioral interventions (R01 DK080102) places them in a unique position to further design and pilot this intervention and ultimately be well poised to run a future full-scale efficacy trial.
