food for thought: virtual home-based family interventions to improve nutrition behaviors

Conditions: Behavior, Health; Obesity, Childhood

Summary: a randomized controlled trial enrolling 123 parent-infant dyads (english or spanish speaking) comparing a virtual video teaching kitchen outreach program (tko) with weekly grocery delivery (comparator group), to healthier families, covid edition (intervention group) which includes tko plus a 12-week virtual health coaching intervention aimed at supporting family goal setting and behavior change including topics such as nutrition and physical activity.

the aim of this work is to conduct a randomized controlled trial to test the effect of two evidenced based programs (healthier families and teaching kitchen outreach (tko) adapted to a virtual platform on improving family health. both the intervention and comparator condition receive up to 12 weekly short (about 2-3 minutes) teaching kitchen outreach (tko) videos. recipe specific groceries are delivered to participants' homes by a third party grocery delivery company, and are available for pickup at a central location(s). these recipes reflect foods that can be purchased with snap and wic and include tested meals and snacks that were developed and evaluated in person in parks and recreation after-school programming (heerman w, elsakary y, sommer e, escarfuller j, barkin s. assessing the scale and spread of an experiential teaching kitchen in after-school programming among school-aged children) through the long-standing nashville collaborative partnership (https://pediatrics.vumc.org/nashville-collaborative). over more than a decade, the nashville collaborative has developed and tested programs together to improve health and wellness and reduce childhood obesity in the local community. those randomized to the intervention condition receive a 12-weekly health coach via a virtual platform (such as zoom, facetime, or what's app) to provide an adapted version of the previously tested healthier families program. adaptations include: shortening each session to 30 minutes and delivering the programming via a virtual platform. the health coach provides the healthier families modules to individual child-parent pairs. any use of zoom for participant participation will use a version of zoom procured through vanderbilt. the virtual version of healthier families was adapted from prior research in the growing right onto wellness (grow) trial that worked with over 600 parent-child dyads and demonstrated a statistically significant effect on health behavior change (barkin sl, heerman wj, sommer ec, martin nc, buchowski ms, schlundt d, po'e ek, burgess le, escarfuller j, pratt c, truesdale kp, stevens j. effect of a behavioral intervention for underserved preschool-age children on change in body mass index: a randomized clinical trial).
