About this study

Rural populations in the U.S. are disproportionately burdened by cardiovascular disease and type 2 diabetes. Lifestyle modification interventions are needed that support long-term engagement in risk-reducing health behaviors. This trial will study the effects of a family-focused, lifestyle intervention that is culturally tailored for use with rural Hispanic and non-Hispanic adults. If successful, this community-based intervention has significant potential for broad dissemination to reduce cardiovascular disease and type 2 diabetes health disparities in rural U.S. communities.

Read the detailed description

The Heart of the Family study is a randomized controlled trial conducted to examine if a virtual lifestyle modification intervention is more effective in reducing risk for type 2 diabetes (T2D) and cardiovascular disease (CVD) when it is delivered to family dyads or to individuals and to compare intervention effects in Hispanic and non-Hispanic rural-dwelling adults at-risk for T2D or CVD. The Heart of the Family study will enroll 360 participants - 180 Hispanics and 180 non-Hispanics - from rural communities who have two or more risk factors for T2D or CVD. Participants will be randomized to participate as an individual or with a family member who may or may not be at risk for T2D or CVD or may or may not have diagnosed T2D or CVD for a total of 540 participants. The interventions for both groups will be provided by community health workers using a virtual platform. Both groups will receive eight educational sessions about healthy lifestyle behaviors and support to address personal and environmental barriers to engaging in healthy behaviors. After the eight sessions, the community health workers will follow up with participants once a month by phone over the next 12 months. Primary outcomes include short-term and long-term impact of the family-focused active intervention compared to the individual-focused control condition on type 2 diabetes and CVD biological risk factors (for example, blood pressure and weight) and behavioral risk factors (for example, physical activity and tobacco use). Outcomes are measured at baseline, immediately post-intervention, and at the end of the 12 month period of the study for both groups.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Active Control Intervention educational sessionsBehavioural

    The participant will attend 8 sessions that provide type 2 diabetes (T2D) and cardiovascular (CVD) risk reduction and lifestyle modification education focused on CVD and T2D risk factor reduction through promotion of participant self-management. Education will concentrate on healthy eating, physical activity, stress reduction, and other lifestyle risk reduction recommendations.

  • Family Dyad InterventionBehavioural

    The participant and a co-participating family member will attend 8 sessions that provide type 2 diabetes (T2D) and cardiovascular (CVD) risk reduction and lifestyle modification education focused on CVD and T2D risk factor reduction through promotion of participant self-management. Education will concentrate on healthy eating, physical activity, stress reduction, and other lifestyle risk reduction recommendations.

Study groupRoleWhat they receive
Active Control ArmActive comparatorAn index participant with 2 or more risk factors for cardiovascular disease or type 2 diabetes who is randomized to this arm will attend 8 weekly educational sessions focused on self-management of risk factors and engagement in healthy behaviors for risk reduction. The index participant will attend the sessions as an individual and will receive standard individual-focused lifestyle modification education.
Receives: Behavioral: Active Control Intervention educational sessions
Family Dyad ArmExperimentalAn index participant with 2 or more risk factors for cardiovascular disease or type 2 diabetes and a co-participating family member will together attend 8 weekly educational sessions focused on self-management of risk factors and engagement in healthy behaviors for risk reduction. The dyadic intervention sessions also incorporate family-focused throughout each session to encourage dyadic support.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in body mass index (BMI)

    BMI based on measurements of weight and height and calculated as kg/m2.

    Measured: 1 year (baseline, 3 months and 12 months)

  2. Change in blood pressure

    Blood pressure assessed using calibrated sphygmomanometry.

    Measured: 1 year (baseline, 3 months and 12 months)

  3. Change in lipid profile

    Lipid profile includes LDL-cholesterol, HDL-cholesterol and triglycerides measured using point-of-care testing obtained by fingerstick.

    Measured: 1 year (at baseline, 3 months and 12 months)

  4. Change in hemoglobin A1c (HbA1c)

    HbA1c will be measured using point-of-care testing obtained by fingerstick.

    Measured: 1 year (at baseline, 3 months and 12 months)

  5. Change in physical activity level

    Physical activity will be measured using the International Physical Activity Questionnaire (IPAQ) to assess the number of days in the last 7 days that the participant engaged in vigorous or moderate physical activity and confirmed by comparing responses to activity levels as determine through actigraphy.

    Measured: 1 year (at baseline, 3 months and 12 months)

  6. Change in dietary intake patterns

    Dietary intake patterns will be assessed using the Vioscreen food frequency questionnaire.

    Measured: 1 year (at baseline, 3 months and 12 months)

  7. Change in tobacco use

    Tobacco use will be confirmed by collection of a saliva sample to determine cotinine levels.

    Measured: 1 year (at baseline, 3 months and 12 months)

Questions about this trial

What is this clinical trial studying?

A study testing Family Dyad Intervention in people with Diabetes Mellitus, Type 2 and Cardiovascular Diseases, run by Gia Mudd 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 22 inclusion and 8 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: finished, as of the sponsor's last update on 9 Mar 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in body mass index (BMI) (time frame: 1 year (baseline, 3 months and 12 months)). The study lists 7 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 9 Mar 2026.
