Arm Label

FBT (family-based behavioral treatment)

FBT+Variety

Arm Description

This condition will be prescribed the Traffic Light Diet (1000-1500 kcal/day, < 2 servings/day of RED [non-nutrient-dense, energy-dense] foods) and a > 60 min/day of MVPA prescription for children and > 30 min/day of MVPA for adults at least 5 days/week. FBT will receive a family-based, behavioral intervention to assist the targeted child and a participating adult caregiver with making changes in energy balance behaviors.

The FBT+Variety condition will receive FBT along with a limited variety prescription. In this prescription families will identify two RED foods, a dinner entree and snack food, and develop meal plans that reduce variety of RED foods by regularly consuming these foods and limiting consumption of other RED entrees and snack foods.

Outcomes

Primary Outcome Measures

Child and adult body mass index
Child's and adult caregiver's weight will be assessed by an electronic scale and height will be measured by a stadiometer.
Child and adult salivary habituation
To assess habituation of salivary responses to food cues, whole mouth parotid salivary flow will be measured using the Strongin-Hinsie Peck method. Two measures will be taken, one with juice and one with food.

Secondary Outcome Measures

Child and adult dietary Intake
Dietary intake for both the child and adult caregiver will be assessed by 3 (2 weekdays and 1 weekend day) 24-hour dietary phone recalls, using the five-step, multiple-pass method. Variables of interest will be the variety of RED foods consumed over the three days; and the mean over the three days of daily servings and kcal from RED foods, kcal, energy density (kcal/g), and Healthy Eating Index (HEI)-2015. Adherence to the prescriptions in the two conditions will be examined. At 6, 12, and 18 months, the percentage of goals met each day will be calculated, with a mean percentage calculated. We will also provide a detailed list of snack foods to participants, and they will be asked to indicate which of the foods on the list were eaten during the previous month, regardless of quantity consumed.
Child and adult physical activity via wGT3X-BT
The wGT9x (ActiGraph, LLC, Pensacola, FL) will objectively measure time spent in MVPA (physical activity at > 3.0 metabolic equivalents units).
Child percent overweight
Percent overweight (%OW) will also be calculated (100*[BMI/50th percentile BMI for child age and sex]).
Child and adult waist circumference
Waist circumference (WC) will be measured using standard procedures.
Meal planning, preparation, and grocery shopping
Parent time scarcity and fatigue as barriers to planning and preparing meals will measure frequency of occurrence of these barriers.
Child eating pathology
Child eating pathology will be assessed using the Kid's Eating Disorder Survey
Home Food Inventory
Self-reported inventory of foods available in the household will be assessed
Child and Adult Sleep Habits
Usual sleeping and waking time will be collected
Child Routines
Parent-report measure of commonly occurring routines in school-aged children will measure the frequency of occurrence of routines in children.
Compliance and process data
Total number of weekly, and type, of self-monitoring records (hard copy or electronic) completed will be assessed. Number of treatment sessions attended will be recorded.

5. Study Description

Brief Summary
The investigators plan to implement a novel limited RED (high-energy-dense) food variety prescription within a 18-month FBT to examine its effect on 18-month body mass index (BMI). This will be the first randomized control trial to examine how habituation rate, assessed via salivary habituation, mediates reduction in RED food intake, overall energy intake, and reductions in BMI over time, as well as if baseline habituation rate is a behavioral phenotype that moderates BMI outcomes. One hundred fifty-six children aged 8 to 12 years at > 85th percentile BMI will be randomized to one of two, 18-month interventions compared in our 6-month pilot study: FBT (family-based behavioral obesity treatment) or FBT+Variety. Child and adult caregiver assessments will occur at 0, 6, 12, and 18 months on anthropometrics, dietary intake (RED food variety, energy, and diet quality), habituation, and physical activity.
Detailed Description
Identifying successful methods for reducing long-term energy intake continues to be a challenge in obesity treatment. Basic behavioral research has found that the rate of habituation (i.e., rate of reduction in physiological and behavioral responding) to food is related to amount of food consumed, and faster habituation rates reduce food intake. The rate of habituation to food can be accelerated when variety in foods is limited, producing decreased intake. Thus, a dietary prescription that limits variety of high-energy-dense (HED) foods may boost ability to reduce long-term energy intake, enhancing long-term weight loss. Furthermore, habituation rates to food show large individual variability. For example, individuals with overweight habituate slower to food than individuals with a healthy weight, and slower habituation rates predict greater increases in child standardized body mass index (ZBMI). Thus, slower habituation rates to food may be a behavioral phenotype for increased risk of suboptimal weight outcomes. Obesity interventions that accelerate habituation to food may then be more beneficial for those with this behavioral phenotype. The investigators have been conducting a line of translational research that applies habituation theory to obesity treatment involving: 1) studies systematically testing basic concepts to better inform intervention development; 2) "proof-of-concept" testing; and 3) efficacy trials. The long-term goal of this research is to develop a dietary prescription that harnesses habituation as a mechanism for reducing long-term energy intake. This research has culminated in piloting a limited variety prescription (variety of both HED snack foods and entrees at dinner were limited) within a 6-month family-based behavioral obesity treatment (FBT) for children. Twenty-four families, with a child > 85th percentile BMI and aged 8 to 12 years, were randomized to FBT that included the Traffic Light Diet (1000-1500 kcal/day, < 2 servings/day of RED [HED] foods) and a > 60 min/day of moderate- to vigorous-intensity physical activity prescription or to FBT that included a limited dietary variety prescription (one RED snack food and dinner entrée were chosen; families regularly consumed these foods as compared to other RED snack foods and entrees) (FBT+Variety). At 6-months children in FBT+Variety had a significantly greater reduction in percent overweight than those in FBT (-15.4% vs.- 8.9%), and families in FBT+Variety had a lower daily intake of kcal from fat (351 kcal vs. 494 kcal). This limited dietary variety prescription shows promise for enhancing weight outcomes in FBT. However, research is needed to examine if limiting variety improves long-term weight loss, if this improvement is due to enhanced habituation, and explore if there is a behavioral phenotype that more greatly benefits from this dietary approach. The investigators plan to implement a novel limited RED food variety prescription within an 18-month FBT to examine its effect on 18-month body mass index (BMI). This will be the first RCT to examine how habituation rate, assessed via salivary habituation, mediates reduction in RED food intake, overall energy intake, and reductions in BMI over time, as well as if baseline habituation rate is a behavioral phenotype that moderates BMI outcomes. One hundred fifty-six children aged 8 to 12 years at > 85th percentile BMI will be randomized to one of two, 18-month interventions compared in our 6-month pilot study: FBT or FBT+Variety. Child and adult caregiver assessments will occur at 0, 6, 12, and 18 months on anthropometrics, dietary intake (RED food variety, energy, and diet quality), habituation, and physical activity. The investigation was designed for all intervention sessions and assessments to be conducted in person. Due to COVID-19, modifications have occurred to the trial for health safety reasons. Initially, all meetings and assessments were to occur in-person. Due to the constant changing health safety requirements due to COVID-19, the trial puts in place health safety practices to maintain the safety of participants. Assessment meetings and program meetings will occur remotely via Zoom. The primary aims are to determine for children: Influence of FBT+Variety on long-term weight loss. Influence of FBT+Variety on long-term habituation to RED foods. The habituation rate will mediate differences in dietary intake and BMI between conditions. An exploratory aim is to examine in children: 1) Influence of habituation rate on moderating outcomes in FBT+Variety and FBT (identifying a behavioral phenotype that bests benefits from a limited variety prescription). Comparisons will also be made between the conditions on all child dietary and activity measures. Additionally, adult caregiver measures will be examined, with outcomes anticipated to be similar to child outcomes.
