Teaching Healthy Responsive Parenting During Infancy to Promote Vital Growth and dEvelopment (THRIVE) Study
Teaching Healthy Responsive Parenting During Infancy to Promote Vital Growth and dEvelopment (THRIVE) Study
Background. Unprecedented rates of overweight and obesity are seen in childhood1 with evidence suggesting that infancy may be a critical period for the development of this high weight trajectory. This has led to a call for proposals for "understanding factors in infancy and early childhood (birth to 24 months) that influence obesity development (PA-18-032)." Objectives. The current study seeks to recruit a sample of mother-infant dyads to pilot a responsive parenting focused obesity prevention program delivered by behavior and development specialists in pediatric primary care. Methods. Approximately 80 mother-infant dyads will be recruited in pediatric primary care at their newborn visit and randomly assigned to one of two groups: a) Healthy Growth (new intervention) or b) Healthy Steps (as usual). We will obtain assessments of growth, feeding, and sleep throughout the study period for infants across five clinic visits and at-home measure completion. Research clinic visits will take place at their regularly scheduled well-child check visits at ages 1, 2, 4, and 6 mos and in-home measures will be completed monthly. The intervention program is hypothesized to show efficacy in both breast and formula fed infants as measured by the primary (i.e., BMI percentile and BMI z-score) and secondary outcomes (e.g., awareness of infant cues, use of alternative soothing strategies, when it is not time for a feeding).
PURPOSE OF STUDY AND OBJECTIVES
This study seeks to pilot deliver an early obesity prevention program in pediatric primary care that has been previously found efficacious when delivered via home visits. Modeled after the principles of the INSIGHT study, (cite) it uses a responsive parenting framework and provides developmentally tailored feeding, sleeping, and soothing guidance to parents of infants. Given its efficacy when delivered during home visits, study investigators aim to examine whether it can be adapted and delivered as part of the prevention work in integrated behavioral health (IBH) primary care practices. Currently, the integrated behavioral health model for prevention work follows the Healthy Steps program. Study investigators aim to compare these two prevention programs to examine if Teaching Healthy Responsive Parenting in Infancy to promote Vital growth and dEvelopment (THRIVE) improves outcomes (i.e., rapid weight gain, soothing, feeding, and sleep) above and beyond seeing a psychologist in a less focused way (Healthy Steps). The intervention will be delivered to 40 families by postdoctoral psychology fellows integrated in a pediatric primary care setting at each infant well-child check (WCC) visit during the first 6 months of life (e.g., 1, 2, 4, 6 mos), while another 40 families will receive care as usual (Healthy Steps) at each WCC during the first 6 months and constitute our control group. The THRIVE program aims to prevent rapid weight gain in infancy, as well as establish healthy eating, sleeping, and self-regulation habits early on in life, by teaching parents responsive parenting principles. More specific portions of the intervention will instruct parents a) to recognize infant hunger and satiety cues and use feeding more selectively in response to hunger only, b) to recognize other reasons for crying or fussy behavior and use alternative soothing strategies when these other reasons apply, c) how to lay the foundation for healthy infant sleep and respond to nighttime awakenings to promote self-soothing, and d) how to introduce complimentary foods at 6 mos, provide repeated exposure to a variety of healthy foods using positive role modeling, and allow infants to determine the amount consumed. In the current study, study investigators have proposed the following aims and hypotheses:
Primary Aims. To develop and pilot an obesity prevention program to be delivered in pediatric primary care at each infant well-child check (WCC) throughout the first 6 months (e.g., 1, 2, 4, 6 mos) and continue to follow families for assessment throughout the first year of life (e.g., follow-up at 9 mos). To evaluate the efficacy/magnitude of effect, feasibility, and acceptability of an individually-tailored, responsive parenting prevention intervention on parent's ability to 1) use alternative strategies to soothe their infant (besides feeding) and to 2) increase their responsive parenting skills, such as attunement, awareness of infant cues (hunger, satiety, sleepy, other fussiness), and responsive feeding from those in the control condition (Healthy Steps).
Primary Aim 1. To evaluate the feasibility of recruitment and retention of mother-infant dyads in primary care and refine assessment procedures to inform the design of an anticipated K23 application.
H1: The intervention format will demonstrate feasibility and acceptability via intervention session attendance and parent report.
Primary Aim 2. To examine if parents' strategies to soothe, feed, and put to sleep their infants differ between those in the intervention arm (THRIVE) compared to the control group (Healthy Steps).
H2a: Parents in the THRIVE group will demonstrate less frequent use of food to soothe infants and a greater use of a variety of other alternative soothing strategies when infant is not hungry.
H2b: Parents in the THRIVE group will report greater attunement, awareness of infant hunger and satiety cues, and responsive feeding.
Exploratory Aim. To examine weight trajectories of infants and estimate effect sizes to detect the relationship between sleep and feeding patterns. Infant anthropometrics will be assessed at ages 1, 2, 4, 6, and 9 mos with growth metrics derived based on US population references.3 H3: Infants in the THRIVE intervention will experience less rapid weight gain compared to infants in the control condition from birth - 9 months.
