The investigators will employ a re-designed RICHH intervention and determine its feasibility and acceptability with custodial grandparents.

The usual care control group will receive mini-iPads loaded with Caregiver and CVD risk reduction pamphlets in PDF format along with the associated links from the American Heart Association. Because the investigators may identify CVD risk factors in baseline testing in participants who do not know they have them, it would be unethical not to provide at least usual standard of care for these. Thus, all individuals enrolled in the study and in whom the investigators identify CVD risk factors will receive referral to a primary care provider for management of the CVD risk factors identified.

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).

Feasibility is measured by the count of participants who complete the intervention and follow-up components of the study

Acceptability will be assessed in the domains of affective attitude, burden, opportunity costs, perceived effectiveness, and self-efficacy

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.

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.

BMI (kg/m2) will be calculated from height and body weight measured

Measured by the average of three consecutive resting blood pressure measurements (both systolic and diastolic pressures).
