Brief summary
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)

Inclusion criteria
* Adults aged 18 or older who are interested in gardening but have no plans to garden in the coming season. * Participants will also be required to: 1) have at least one child (aged 5-17) living in the household with them * Have access to space for a garden (either at home or in a community garden space where they could plant any combination of in-ground, raised beds, and/or container gardens * Have a smartphone capable of downloading an app and syncing with a Fitbit * Access to the internet * Have or are willing to create a Facebook account * Report ≤90 minutes of moderate or vigorous physical activity /week * Report \<5 servings of fruit and vegetables per day * Have any one additional self-reported CVD risk factor (e.g., BMI ≥25, family history of premature CVD, high blood pressure, high cholesterol, diabetes, current or past tobacco use)
Exclusion criteria
* Adults who are pregnant * Have medical conditions that significantly limit an individual's ability to participate in gardening (e.g., knee or back pain, heart attack/stroke in the past year, recent or pending surgeries * Uncontrolled allergies, other serious physical disabilities, uncontrolled asthma) * Medical conditions that may limit participants from increasing FV intake (e.g., kidney failure or dialysis)
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Dietary Intake: Fruit and vegetable (FV) intake | Baseline | Trained interviewers at the Penn State Diet Assessment Center, will collect 24-hour dietary recalls (one weekday and one weekend day) by phone within one week of each scheduled study visit at 4 time points. Diet data will be analyzed using the Nutrition Data System for Research (NDSR) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Physical Activity - Fitbit activity volume via step count | Baseline | This data will be collected via wrist worn Fitbit Inspire 3 devices |
| Biomarkers - total cholesterol | Baseline | These at-home, blood collection devices will be used to collect results for markers of cardiometabolic disease |
| Biomarkers - HDL | Baseline | These at-home, blood collection devices will be used to collect results for markers of cardiometabolic disease |
| Biomarkers -LDL | Baseline | These at-home, blood collection devices will be used to collect results for markers of cardiometabolic disease |
| Biomarkers -HbA1c | Baseline | These at-home, blood collection devices will be used to collect results for markers of cardiometabolic disease |
| Biomarkers -triglycerides | Baseline | These at-home, blood collection devices will be used to collect results for markers of cardiometabolic disease |
| Blood Pressure | Baseline | The blood pressure cuffs will be used to monitor participants' cardiovascular health. These devices will be used to collect blood pressure data at baseline, midpoint, and follow-up assessments. |
| Measure Height | Baseline | Height measurement tools will be used to assess changes in participant height for BMI calculation. |
| Measure Weight | Baseline | Scales will be used to measure participants' weight and monitor changes in weight status. Accurate weight measurements are essential for Aim 1 to assess the participants' risk for obesity and other cardiovascular conditions. This will be collected on adults and children |
| Household Food Security | Baseline | 18-item United States Household Food Security Survey Module will assess home food security for adults and children. Scale yields scores from 0-18 with lower scores indicating higher food security. |
| General Nutrition Knowledge | Baseline | General Nutrition Knowledge Questionnaire will assess knowledge of general healthy eating information (score range 0-35, where higher score means a better outcome) |
| Home Meal Preparation | Baseline | The National Health and Nutrition Examination Survey (NHANES) Home meal preparation questionnaire will assess the number of evening meals prepared per week (range 0-7 with higher number equating to more evening meals prepared). |
| Cooking skills | Baseline | The Cooking and Food Skills Questionnaire yields a total score with a range from 33-231 with higher scores indicating better skills. |
| Social support | Baseline | The Social Support for Diet and Exercise Behavior survey measures social support from friends and family with higher scores indicating more social support for these behaviors (score range 0-115). |
