Intervention INC: An Interactive Family-centered mHealth Tool to Reduce Obesity Risk in Urban Minority Preadolescents

April 7, 2025 updated by: Tufts University
Using a two-group randomized study design, this study aims to evaluate the effectiveness of the adapted family-centered mHealth tool on child BMI z-score (primary outcome), child dietary behaviors, and parental feeding practices, from baseline to 12-month follow-up, among 200 child-parent dyads. It is hypothesized that children in the experimental group will demonstrate larger BMI-z score improvements between baseline and 12-month follow-up compared to children in the comparison group.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Recruiting

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

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.

Detailed Description

Childhood obesity continues to be a serious clinical and public health issue in the United States (US), particularly within low-income, minority groups. Effective, yet engaging interventions, such as the one developed by our team, are needed to capture the attention of children living in a multi-media environment.

Potentially eligible pediatric patients (and their parent/caregiver) will be recruited from two of Children's Aid community-based clinics in NYC - Dunlevy Milbank Center based in Harlem and the Bronx Health Center based in the South Bronx. A variety of recruitment methods will be deployed, including in-person/flyer-based recruitment in clinic waiting rooms, healthcare provider referrals, and direct calls.

At baseline, eligible participants will be randomized to either the experimental group or comparison group (allocation ratio 1:1). Randomization will be performed at the dyad level and will be balanced on child ethnicity (Hispanic or Non-Hispanic), child biological sex (male, female), and clinic site.

The experimental group will receive access to Intervention INC, a theory-guided interactive, family-centered web-based tool promoting healthy dietary behaviors. The comparison group will receive access to web-based newsletters focused on promoting healthy dietary behaviors. To minimize bias, participants will be blinded to the study's hypothesis.

Data will be collected at four timepoints: baseline (T1), main intervention end (T2), maintenance intervention end (T3), and at 12-month follow-up (T4). The primary outcome measure (BMI z-score) will be calculated using height and weight data captured via combined scale/stadiometer by a trained healthcare provider at T1, T3, T4. Secondary measures (dietary intake and dietary knowledge & attitudes of child participants; feeding practices and the home food environment by the parent/caregiver) will be captured via questionnaires at T1, T2, T3, T4.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
