Based on inclusion/exclusion criteria, potential study participants (child and parent) will be identified by the Collaborating Site PI/primary contact and sent a recruitment letter signed by the Primary Investigator and a Collaborating Site PI/primary contact.

Children's Aid Society (CAS) and Weill Cornell Medical College (WCMC) will act as collaborating sites. WCMC PI is Dr. Allison Gorman, who will assist with identifying potential study participants from their government insured medical clinics. All recruitment protocols will be approved by the IRB at WCMC (pending Hunter IRB approval). Once the letter of approval has been received from WCMC, it will be forwarded to CUNY's HRPP. CAS primary contact is Alyson Abrami. Ms. Abrami and the CAS Milbank Medical Clinic will facilitate access to potential study participants. CAS is aware of the study protocols and the administration is in support of the study and its potential impact on their patient population.

Study staff will contact potential study participants by phone and ask additional screening questions to determine study eligibility. A baseline in-person study visit will be scheduled for eligible participants. We are aiming to recruit a total of 82 child/parent dyads (41 in the intervention and control group, respectively). In the intervention group, children will have access to a web-based interactive nutrition comic and receive health messages from comic characters by email and/or text, while parents will receive weekly newsletters related to nutrition and health by email and/or text. In the control group, children and parents will receive didactic health information and resources by email and/or text. The delivery mode of the health messages will be based on based on personal preference.

Aside from usage data of the online tool by each child/parent (e.g. average time spent per login using online tool, collected on an ongoing basis throughout 6-week intervention), data will be collected at four different times points in the study: baseline (T1), after 3 weeks or halfway through the intervention (T2-only children), after 6 weeks or at the end of the intervention (T3), and 3 months post-intervention (T4). T1 and T4 will be in-person study visits at either CUNY Hunter College or CAS Milbank. At baseline (T1), the child's height and weight will be measured to confirm meeting BMI eligibility criteria. After the child and parent completes consent/assent forms, they will be randomized to either the intervention group or control group. Both the child and parent will complete baseline survey measures (will take 20-30 minutes to complete) and attend a study orientation session (10-15 minutes). The baseline visit should take about 1 hour. At T2 (child-only) and T3 (child and parent), data collection (survey measures and open-ended questions) will be conducted either on the phone or by videochat in a private area, according to the participant preference, and will take approximately 30 minutes per person. At T4, the child's height and weight will be measured, and both the child and parent will complete survey measures (will take approximately 45 minutes to complete). Both the child and parent will be compensated for completing survey measures (see Participants-Compensation section for more details).

Open-ended questions collected at timepoint T3 (over the phone or videochat) will be audio recorded (only intervention arm participants). Even though participants will have signed consent to be audio recorded during data collection, the participant will be asked during the phone call or videochat session at T3 if the following open-ended questions could be audio recorded to be reviewed in more detail afterwards. Additionally, open-ended questions related to the experience and context of using the web-based nutrition comic will be asked of a subset of parents and children (intervention arm only) at timepoint T3 (over the phone or videochat). Their responses will also be audio recorded as this is qualitative data that will be transcribed and analyzed separately from survey data.
