Brief Summary: This study is designed to translate an evidence-based family-based weight loss treatment for childhood obesity (FBT) into primary care settings using co-located interventionists to serve as a model for care delivered within a patient-centered medical home. FBT will be compared to usual care (UC), and the families will be followed for a 2 year period to assess between group differences in the targeted child and parent outcomes, weight changes in non-targeted siblings who are overweight/obese, parent and child changes in delay of gratification, and how these changes relate to weight loss, and the assessment of how provider attitudes predict their intention to use FBT in the future. The results of this study will inform future dissemination and implementation of FBT into primary care settings.

Detailed Description: Family-based treatment (FBT) is a behavioral weight control intervention that targets children who have overweight/obesity and their parents, and has the capacity to improve the weight status of non-targeted family members such as siblings. FBT has significant positive effects on body weight in children for up to 10-years of follow-up, and a robust relationship is observed between child and parent outcomes. FBT's concurrent care of two generations of obesity in the family is more efficacious and cost-effective than if family members are treated by their separate health care providers. Despite its recognized efficacy, FBT is mainly available in specialty clinics and many children fail to receive this guideline-based level of treatment, as recommended by the U.S. Preventive Services Task Force. Primary care offers an optimal setting for delivery of FBT by capitalizing on the established relationship between primary care providers and families. Using interventionists co-located within the primary care setting overcomes barriers posed by fragmentation of care, and lack of provider time and training. One of the challenges to integrating childhood obesity treatment into primary care is optimizing limited health care resources. In behavioral weight loss programs, some individuals learn diet, physical activity, and behavior change information quickly, while others learn more slowly. Individuals also differ in their ability to implement treatment recommendations due to individual differences, such as problems with delaying gratification. FBT accommodates these individual differences by using a personalized system of instruction, or a mastery model, in which the content and dose of treatment is calibrated to the needs of the family, ensuring that treatment effort is consistent with need. This multi-site, clinical trial aims to evaluate over a two year period the effectiveness of FBT delivered by a trained interventionist co-located within primary care plus usual care delivered by the primary care provider (FBT) compared to usual care (UC). Participants will be a representative sample of 528 families with a 6-12 year-old child and a parent who have both overweight/obesity. Weight changes in approximately 228 siblings who have overweight/obesity and between 2-18 years of age will also be studied. This study will test between group differences in child (Primary Specific Aim 1A) and parent (Secondary Specific Aim 1) weight change, as well as weight change in siblings who have overweight/obesity (Secondary Aim 2), changes in parent and child delay of gratification, and how changes in delay of gratification are related to parent and child weight changes (Secondary Aim 3), participant level predictors of treatment success (Secondary Aim 4), and how provider attitudes toward evidence-based treatment and perceptions of FBT may relate to their intention to use colocated FBT in their practices in the future (Exploratory Aim 1). Establishing that FBT can be effectively implemented within real world settings is crucial to creating a system by which children and their families who suffer from obesity can be treated in a centralized primary care setting.

Inclusion Criteria

Exclusion Criteria

The participating parent or child will not have had a concussion in the past three months; will not have any significant developmental delays or intellectual disabilities; will not be receiving treatment for a Diagnostic and Statistical Manual Diploma in Social Medicine (DSM-5) disorder that interferes with treatment delivered as part of the intervention; will not have a physical disability or diagnosis that prevents performance of physical activity at a level equivalent to a brisk walk or that places severe restriction on diet; will not be on a medication regimen that affects weight; will not have a medical condition that alters nutritional status, intestinal absorption, or affects weight; will not have undergone weight loss surgery; and will not be participating in an alternate weight control program. Families in which either the participating child or parent is actively involved in other weight-loss treatment, is using weight-affecting medications, or has an impairing psychiatric or medical condition that would hinder participation in the study will be excluded as identified by the screening assessments. Families that are planning to move or in which the participating parent is pregnant or is planning on becoming pregnant during the 2 year study period will also be excluded.

Arm && Interventions

Group	Intervention	Description
Family-based treatment (FBT)	Family-based treatment	Family- Based treatment utilizes behavior change techniques to target family-wide changes in diet and physical activity habits with the goal of promoting weight loss and subsequently healthy weight maintenance in all participants. Participants will have visits between 30 to 60 minutes as frequent as weekly and no longer than monthly over the two year study
Usual Care (UC)	Usual Care	Usual Care will consist of the care typically delivered by the family's primary care provider for children with overweight or obesity. The implementations of UC may vary between providers but typically includes and assessment of the child's weight, help remove barriers to weight loss and introductions of goals for better weight management.

Primary Outcome Measures

Name	Time	Method
Body Composition Measures of Targeted Child. Percent Change Over the Median BMI	0 - 24 months	Height and weight will be taken to calculate changes in over weight status for children in FBT versus UC. Change in percent over median BMI from baseline to 24-month. Percent over the age- and sex-specific 50th BMI percentile for kids, percent over the sex-specific 50th BMI percentile for 20-year-olds for parents. Parents are not included in this measurement. This measurement is to describe child body composition and not used for parents. Results are pooled across 10 multiple imputations and reported as mean (standard error)

Secondary Outcome Measures

Name	Time	Method
Body Composition Measures of Participating Parent. BMI (kg/m^2) Change From Baseline to 24 Month	0-24 months	Height and weight will be taken to calculate changes in over weight status for parents in FBT versus UC. Results are pooled across 10 multiple imputations and reported as mean (standard error)
Body Composition Measures, Siblings	0-24 months	Height and weight will be taken for non-targeted siblings to determine if weight loss effects of FBT extend beyond the participating parent and child.
Delay Discounting	0, and 24 months	Delay discounting will be measured using an adjusting amount discounting task with a delayed reward of $100. K-values will be calculated and log-versions will be used due to skewness of k-values. More negative k-values indicate more delayed choices, which is considered better decision making
