Enhancing BodyWorks: A Canine Health Literacy Module (BW)

June 5, 2026 updated by: Larry Yin, Children's Hospital Los Angeles

A Health-literacy Module for Overweight Adolescents and Their Parents on Canine Physical Activity, Nutrition and Behavior: Enhancing Department of Health and Human Services' (DHHS) BodyWorks Program at a Federally Qualified Health Center

Dog ownership can serve as a vehicle for large-scale multi-level public health interventions, especially for pediatric overweight and obesity, due to dogs' unique place in children and adolescents' social networks.This study develops and tests a novel approach to design a Canine Health-Literacy module to enhance a Comprehensive Family Lifestyle Intervention BodyWorks, for dog-owning adolescents who have been diagnosed with overweight or obesity, and their parents. The results are anticipated to make an important step towards addressing the overweight and obesity epidemic among both people and companion dogs in the U.S.

Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This project is a feasibility, acceptability, and pilot study that leverages the psychosocial benefits of informed and attached dog ownership among treatment-naïve overweight or obese adolescents. It is based upon a socioecological model of health behavior that pursues multiple levels of influence, including those extending across species lines such as physical activity. BodyWorks, a Comprehensive Behavioral Family Lifestyle Interventions (CBFLI), a national, empirically validated, curriculum-based 8-week program (orientation and 7 weeks of curriculum) will be offered at Children's Hospital Los Angeles AltaMed Division of General Pediatrics, a Federally Qualified Healthcare Center. The aims of the study are: Specific Aim 1: Using current empirical evidence in veterinary medicine, to develop a Canine Health Literacy module (CHL) to be delivered as part of the existing, empirically tested BW curriculum to increase adolescents' health literacy about their dogs' physical activity needs, weight status, and nutrition. Specific Aim 2: Test the feasibility and acceptability of a concurrent approach using physical activity trackers and Ecological Momentary Assessment. 2(a): Test the feasibility and acceptability of objective measurement of physical activity using wireless fitness trackers for adolescents (FitBit Inspire), their parents (FitBit Inspire), and their dogs (FitBark); 2(b): Test the feasibility and acceptability of using mobile phones for Ecological Momentary Assessment of types and contexts of adolescent's physical activity with dogs. Specific Aim 3: To establish the size of the effect, and the variability associated with the 8 week-long BW + CHL module, as compared with the control group who received the standard BW program in 3(a) adolescents' positive affect during or after physical activity with the dog, as measured by the Ecological Momentary Assessment using prompts on mobile phones; and 3(b) levels of overall physical activity for the adolescents, their parents, and the dogs as measured by the FitBit Ace (adolescents), FitBit Flex2 (parents), and FitBark (dogs). The project will establish feasibility, acceptability, attrition, and protocol compliance, and will collect pilot data needed for power calculations in preparation for an R01 Randomized Controlled Trial as a next step to test the effectiveness of our enhanced BW+CHL program. This project represents a significant methodological and theoretical advancement in the field of Human-Animal Interaction (HAI) and in research on overweight and obesity.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Intervention
Half of the BodyWorks families will be randomized to the intervention group, and will receive a PAT for the children, the parents, and the dogs at the beginning of the cycle; the children will respond to EMA surveys using a cell phone; the children and the parents will receive the Canine health literacy module in addition to the BW curriculum.
Behavioral: BodyWorks Intervention
BodyWorks (BW), a Comprehensive Behavioral Family Lifestyle Interventions (CBFLI), a national, empirically validated, curriculum-based 7-week program will be implemented (Borden et al., 2012; DHHS, 2013)
Behavioral: Canine Curriculum
Using our team's expertise in veterinary medicine, human-animal interaction, and animal behavior modification, develop an empirically-based, 7-week module on canine health and behavior.
Behavioral: Ecological Momentary Assessment
Ecological Momentary Assessments (EMA) of physical activity will be conducted using mobile phones for 7 weeks of the BW program, prospectively collecting data on 4 days per week (Saturday to Tuesday) (Dunton et al., 2011; Liao et al., 2016).
Behavioral: Physical Activity Trackers
Three types of consumer-grade wireless personal activity trackers (PATs): FitBit Inspire® designed for children 8 years of age and older; FitBit Inspire® for adults (Diaz et al., 2015; Espinoza et al., 2017); and FitBark®, wireless, global positioning systems (GPS)-based personal activity trackers for dogs (Patel et al., 2017). This approach will allow us to evaluate quantity (number of steps) and intensity of physical activity in the adolescents, their parents, and their dogs, as well as to synchronize Fitbit Ace and FitBark to establish the amount of shared physical activity of adolescents and their dogs.
Active Comparator: Control
Half of the BodyWorks participants will be randomized to the control group and will receive a PAT at the beginning of the cycle for the children, the parents, and the dogs, and the children will respond to EMA surveys using cell phones.
