Status Not yet recruiting

Clinical Trial Summary

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.

Clinical Trial 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. ;
