About this study

Official title: COACH: Competency Based Approaches for Community Health 2

One-size-fits-all approaches have failed to demonstrate sustained effects on childhood obesity, especially among low-income minority families, who experience constantly changing barriers to engaging in health behavior. Addressing obesity in these populations requires intervening in early childhood and situating interventions in the context of families and communities. Developing personalized childhood obesity prevention interventions with sustained effectiveness that support families in health behaviors despite dynamic barriers could address chronic disease risk and health disparities in low-income and minority communities.

Read the detailed description

Despite the recognition of health disparities in obesity, behavioral interventions among low-income and minority populations have consistently met with limited success. This is partially explained by social determinants of health. Constantly changing barriers at the household and community levels impede consistent engagement in healthy behaviors. The current proposal tests a novel, culturally-tailored and multi-level intervention designed to teach families to overcome dynamic barriers as the logical next step to address obesity among low-income Latino families. It is based on the premise that by implementing a personalized multi-level intervention that simultaneously addresses healthy weight for parents and children, we will improve body mass index (BMI) among Latino parent-child pairs.

COACH (COmpetency-Based Approaches to Community Health) implements a personally tailored approach, equipping families to engage in health behaviors despite dynamic barriers. COACH is a multi-level intervention targeting 1) the individual child through developmentally appropriate health behavior curriculum, 2) the family by addressing parent weight loss directly and engaging parents as agents of change for their children, and 3) the community by building capacity of Parks and Rec centers to offer parent-child programming. Using novel multi-component assessments throughout the study, the intervention identifies individual, family, and community barriers to healthy behaviors and delivers structured yet personalized intervention content in 7 domains: fruits/vegetables, snacks, sugary drinks, physical activity, sleep, media use, and parenting.

Building on a successful pilot, this proposal will implement a randomized controlled trial to test the effectiveness of COACH compared to an attention-matched school-readiness control group. We will enroll 300 parent-child pairs from Latino communities in Nashville, TN.

The goals of COACH are to 1) implement a novel personalized behavioral intervention, 2) test a two-generation solution to obesity, 3) address health disparities by reducing obesity among Latino families, and 4) develop a scalable and widely accessible approach to behavioral obesity interventions by delivering them in Parks and Rec centers.

Study groupRoleWhat they receive
COACH InterventionExperimentalCOACH is a multi-level intervention, consisting of 1) developmentally appropriate health curriculum for 4-6 year old children; 2) family-based content that both targets parent weight loss and leverages a shared parent-child experience to improve family health behaviors; 3) community-level intervention to improve access and quality of family-based programming at local Parks and Rec centers.
Receives: Behavioral: COACH
Educational ControlActive comparatorThe control arm will consist of a school readiness intervention developed by education and literacy experts on our team and implemented at local libraries. It will include 1) child lessons from Puente de Cuentos, a systematic, language-based curriculum focused on dual language storytelling (narrative language), and 2) parent sessions designed to improve parents' knowledge and skills related to improving children's language production and storytelling skills, to ultimately support school readiness.

Questions about this trial

What is this clinical trial studying?

A study testing COACH and School Readiness Intervention in people with Obesity, run by Vanderbilt University Medical Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 30 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 2 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Child Body Mass Index (time frame: 24-month follow-up). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Dec 2025.
