Live Long, Heart Strong: A Digital Nutrition Intervention for Emerging Adults

60 participantsStarted 2027-01

Plain-language summary

Live Long, Heart Strong (LLHS) is a theory-guided, digital twin-supported nutrition intervention designed to promote cardiovascular health behaviors among emerging adults (18-25 years). Developed using a human-centered design approach and informed by Social Cognitive Theory, the intervention incorporates personalized nutrition education, interactive learning activities, goal setting, self-monitoring, quizzes, youth-informed educational videos, tailored feedback, reminders, and gamification to support healthy eating behaviors and improve dietary quality. In this pilot randomized controlled trial, participants will be randomly assigned to either the LLHS intervention or an active comparator consisting of a static, non-personalized digital nutrition education toolkit containing similar evidence-based educational content without personalization, interactivity, or behavioral support features. The study will evaluate implementation outcomes (feasibility, usability, acceptability, and appropriateness), changes in psychosocial and behavioral outcomes related to healthy eating, and preliminary cardiovascular-related health indicators. Findings will inform continued refinement of the LLHS intervention and the design of a future fully powered efficacy trial.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Participants are eligible if they: * Are 18 to 25 years old. * Are able to read and understand English. * Reside in Texas at the time of the study. * Own a smartphone with internet access. * Are willing to be randomized to either study group, attend baseline and post-intervention study visits, and complete study assessments. * Provide informed consent. Participants are excluded if they: * Are younger than 18 years or older than 25 years. * Are unable to read or understand English. * Do not have reliable access to a smartphone with internet access. * Are unable or unwilling to provide informed consent. * Are currently participating in another nutrition, weight management, or cardiovascular health intervention study that could affect study outcomes. * Have a medical condition or dietary restriction that requires a highly specialized diet and would make the general LLHS nutrition content inappropriate without clinical supervision.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1This trial is focused on changing eating behaviors in 'emerging adults' — would I actually fit the target age group and health profile they're looking for, or is this study aimed at a different population than where I am right now?
2Since this is a digital nutrition intervention and the trial is 'not yet recruiting,' how long might I realistically have to wait before it opens, and is there something I should be doing in the meantime to support my heart health through diet?
3The study is measuring feasibility, usability, and acceptability rather than health outcomes like weight or cholesterol — what does that mean for what I'd actually learn about whether this approach would help me personally?
4Because this is a Phase NA feasibility study, would the researchers mainly be figuring out whether the program works well enough to test further, and does that mean there's less evidence right now about whether it produces real health benefits?
5Are there existing, evidence-based nutrition programs or dietary counseling options my care team already offers that might give me similar guidance while I wait to see if this trial opens up?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
