About this study

Official title: Growing Healthy Hearts: A Randomized Controlled Trial of a Multicomponent Gardening Intervention for Adults With Cardiovascular Disease Risk and Their Families.

This proposal includes a prospective, parallel group, two-arm RCT with 264 adult-child dyads (adult age 18+, child ages 5-17 years) to examine the effectiveness of the Growing Healthy Hearts (GHH) intervention versus a wait list control on cardiovascular and behavioral health outcomes at 3-, 6- and 12-months follow-up (Aim 1). This proposal will also examine the effect of GHH on home fruit and vegetable (FV) availability, frequency of home-prepared meals that include FV, and child behaviors (FV intake and PA) at 3-, 6- and 12-month follow-up (Aim 2) and intervention implementation (Aim 3)

Questions about this trial

What is this clinical trial studying?

A study testing GHH Intervention in people with Cardiovascular (CV) Risk and Behavioral Changes, run by Milton S. Hershey 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 9 inclusion and 4 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: opening soon, as of the sponsor's last update on 7 Jul 2026. 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?

Contact Susan Veldheer, DEd, RD (717-531-5625, sveldheer@psu.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Dietary Intake: Fruit and vegetable (FV) intake (time frame: Baseline). The study lists 4 primary outcomes in all. 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 7 Jul 2026.
