Brief summary
In this study, the investigators will tailor an existing intervention (Rural Caregiver Heart Health Education (RICHH)) protocol and test its feasibility, acceptability, and initial effect with grandparent caregivers.
Interventions
BEHAVIORALModified RICHH
The RICHH intervention is an educational-behavioral and counseling intervention that promotes caregivers' knowledge, skills and motivation to engage in CVD risk reduction. The intervention is delivered individually to caregivers in their homes using video-conferencing technology on mini-iPads. The program consists of 12 weekly sessions \[30-45 minutes\] that will be held at the caregivers' preferred times. RICHH consists of 6 interactive modules (i.e., self-management for heart health, depressive symptom management, heart healthy eating, physical activity, co-morbid condition management, and adherence to medication and smoking cessation). The modified RICHH intervention utilizes focus group outcomes to employ modifications needed to target custodial grandparents from varied backgrounds (e.g., high ACEs, SDoH groups).

Inclusion criteria
Grandparent (inclusion): * Provides full-time care to at least one grandchild (\< 18 years old) for at least 6 months, with no biological parent residing in the household or providing substantial care to the children * Lives in Oregon * Has English proficiency sufficient for informed consent and completion of study measures * Provides signed informed consent Grandparent (exclusion) * Plans for transfer of care to other caregivers or setting for the next 12 months * Has significant physical or emotional impairment, or psychiatric illness that might interfere with engagement in their own self-management or that is likely to result in their needing a caregiver in the next 12 months * Chronic drug abuse * Current active cancer (i.e., undergoing active treatment for cancer) other than isolated skin cancer
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of participants who complete the intervention and follow-up | 4 months after baseline and 6 months after baseline | Feasibility is measured by the count of participants who complete the intervention and follow-up components of the study |
| Percentage of participants who indicate acceptability of study intervention | 4 months after baseline | Acceptability will be assessed in the domains of affective attitude, burden, opportunity costs, perceived effectiveness, and self-efficacy |
| Physical activity | At baseline, 4 months after baseline, and 6 months after baseline | Measured using ActiGraph GT9X Link devices. The ActiGraph algorithms generate accurate and reliable data on total energy expenditure (kcal/day). Participants will wear the devices over 7-day periods at each data collection point. For each participant, the average proportion of time per day in moderate-to-vigorous physical activity (MVPA), out of total time wearing the monitors, will be calculated. |
| Food intake | At baseline, 4 months after baseline, and 6 months after baseline | Measured using the self-report Viocare Food Frequency Questionnaire. Data from Viocare will be used to generate Healthy Eating Index scores, which range from 0 to 100. Higher scores indicate better dietary quality. |
| Body mass index | At baseline, 4 months after baseline, and 6 months after baseline | BMI (kg/m2) will be calculated from height and body weight measured |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Blood pressure | At baseline, 4 months after baseline, and 6 months after baseline | Measured by the average of three consecutive resting blood pressure measurements (both systolic and diastolic pressures). |
| Lipids | At baseline, 4 months after baseline, and 6 months after baseline | Measured using non-fasting total cholesterol obtained via finger stick |
| Hemoglobin A1c (HbA1c) | At baseline, 4 months after baseline, and 6 months after baseline | Measured using non-fasting HbA1c obtained via finger stick |
| Nicotine exposure | At baseline, 4 months after baseline, and 6 months after baseline | Assessed via self-report of cigarette use/inhaled nicotine use, or secondhand smoke exposure. AHA Life's Essential 8 algorithm will generate a score (0-100), with lower scores indicating greater risk. |
| Depressive symptoms | At baseline, 4 months after baseline, and 6 months after baseline | Depressive symptoms will be assessed using the Patient Health Questionnaire-9 (PHQ-9). Scores range from 0 to 27, with higher scores indicating more severe depressive symptoms. |
| Waist circumference | At baseline, 4 months after baseline, and 6 months after baseline | Waist circumference will be measured using a nonextensible tape. At least two independent measurements will be taken and averaged. |
