Interpretive Summary: The iHeart rhythm project is a sleep and circadian-focused mobile health intervention for the prevention of accelerated summer weight gain among 5–8-year-olds. This pilot study will examine the feasibility, acceptability, and preliminary efficacy of the iHeart rhythm intervention. This will ensure that the research protocol and procedures work as desired and are acceptable to families in preparation for a larger trial clinical trial in which the efficacy of the intervention will be tested. The current study will use a 2-group design (treatment and no-treatment control). A sample of 40 parent-child dyads will be recruited. This study was approved by the institutional review board of Baylor College of Medicine. Recruitment began in March 2021. As of March 2022, data collection and recruitment are ongoing. This study will address the role of sleep and circadian rhythms in the prevention of accelerated summer weight gain and assess the intervention's effects on the long-term prevention of child obesity.

Technical Abstract: The iHeart rhythm project is a mobile health adaptation of interpersonal and social rhythm therapy designed to promote healthy sleep and behavioral rhythms among 5-8-year olds during summer for the prevention of accelerated summer weight gain. This pilot study will examine the feasibility, acceptability, and preliminary efficacy of the iheartrhythm intervention. This will ensure that the research protocol and procedures work as desired and are acceptable to families in preparation for the fully powered randomized controlled trial. The proposed study will examine the willingness of participants to participate in the intervention and determine whether modifications to the intervention, procedures, and measures are needed before conducting a fully powered study. We will assess our ability to (1) recruit, consent, and retain participants; (2) deliver the intervention; (3) implement the study and assessment procedures; (4) assess the reliability of the proposed measures; and (5) assess the acceptability of the intervention and assessment protocol. This study will employ a single-blinded 2-group randomized control design (treatment and no-treatment control) with randomization occurring after baseline (Time 0) and 3 additional evaluation periods (postintervention [Time 1], and 9 months [Time 2] and 12 months after intervention [Time 3]). A sample of 40 parent-child dyads will be recruited. This study was approved by the institutional review board of Baylor College of Medicine (H-47369). Recruitment began in March 2021. As of March 2022, data collection and recruitment are ongoing. This study will address the role of sleep and circadian rhythms in the prevention of accelerated summer weight gain and assess the intervention's effects on the long-term prevention of child obesity.
