Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Life Simple 7(LS7 the metrics for defining ideal cardiovascular health) score at 6-month follow-up | 6 months | The LS7 score consists of 4 behavioral and 3 clinical measures. The behavioral measures are smoking, body Mass Index (BMI), physical activity and healthy dietary pattern. The clinical measures are blood pressure, total cholesterol and fasting plasma glucose.Each LS7 component will be given a point score of 0, 1, or 2 to represent poor, intermediate, or ideal health, respectively. Then, an overall LS7 score ranging from 0 to 14 will be calculated as the sum of the LS7 component scores. The overall LS7 score will be further classified as inadequate (0-4), average (5-9), or optimum (10-14) cardiovascular health. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Weight | Baseline, then monthly through Month 6 | Participants will report their weight in pounds once per month during the intervention period. |
| Change in Tobacco Use | Baseline, then monthly through Month 6 | Participants will report whether or not they have used tobacco once per month during the intervention period. |
| Self management skills acquired | 6 months | Self management skills are patterned on the AADE 7 self care behaviors. A skill is acquired when the participant reports a score of 7 or higher on a 10-point scale. Healthy Coping Healthy Eating Being Active Monitoring Taking Medication Problem Solving Reducing Risks |
| Change in Systolic Blood Pressure: | Baseline, Month 6 | Blood pressure readings will be made three times with the subject at rest in the sitting position using a cuff of the appropriate size and a standardized procedure. The average of the three systolic blood pressure measurements will be calculated. Blood pressure will be categorized according to Joint National Committee recommendations. |
| Change in Diastolic Blood Pressure | Baseline, Month 6 | Blood pressure readings will be made three times with the subject at rest in the sitting position using a cuff of the appropriate size and a standardized procedure. The average of the three diastolic blood pressure measurements will be calculated. Blood pressure will be categorized according to Joint National Committee recommendations. |
| Change in Delta Nutrition Intervention Research Initiative Food Frequency Questionnaire (Delta NIRI FFQ) | Baseline, Month 6 | Dietary intake of fruits and vegetables will be assessed using the Lower Mississippi Delta Nutrition Intervention Research Initiative food frequency questionnaire (Delta NIRI FFQ). The Delta NIRI FFQ is a 283-item, interviewer administered questionnaire that asks if respondents have had certain food items in the past 24 hours, including foods that are commonly consumed in the southern United States. |
| Change in Blood Glucose | Baseline, Month 3, Month 6 | Blood glucose will be measured as milligrams per deciliter at Baseline, 3 months after the start of the intervention and at the end of the intervention at month 6. Normal, fasting blood glucose levels are between 70 to 100 mg/dL. |
| Change in Distance Walked Daily | Baseline, Month 3, Month 6 | The total distance walked daily in miles will be measured by a pedometer or the exercise application for mobile devices. |
| Change in Short Form-12 Health Survey Questionnaire (SF-12) score | Baseline, Month 3, Month 6 | The Short Form-12 Health Survey Questionnaire (SF-12) is a measure of general physical and mental health. The SF-12 consists of 12 items with a Likert-type response format that measures quality of life with a Physical Component Summary (PCS) and Mental Component Summary (MCS). Subscales associated with the PCS include physical functioning, role limitations due to physical problems, bodily pain, and general health perceptions. Subscales associated with the MCS include vitality (energy and fatigue), social functioning, role limitations due to emotional problems, and mental health. The total score for each subscale ranges from 0 to 100 and low values represent a poor health state while high values represent a good health state. |
| Change in Stress Management | Baseline, then monthly through Month 6 | Participants will report on their stress management monthly via free text responses in an online format. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Change in High-sensitivity C-reactive Protein (HsCRP) | Baseline, Month 6 | C-reactive protein (CRP) is a biomarker of cardiovascular health which increases in the blood when inflammation is present. The Hs-CRP test can measure low levels of CRP which indicate the risk of developing cardiovascular disease (CVD). A measurement of less than 1.0 milligrams of CRP per liter of blood (mg/L) is defined as low risk, 1.0 to 3.0 mg/ L is average risk, and above 3.0 mg/L is high risk of developing CVD |
| Change in Plasma Cysteine | Baseline, Month 6 | Plasma cysteine is a biomarker of oxidative stress, which is implicated in the pathophysiology of multiple conditions including cardiovascular disease (CVD). Higher levels of cysteine are associated with increased risk of CVD. |
| Change in Cystine | Baseline, Month 6 | Cystine is the oxidized form of cysteine. Higher plasma levels of cystine are associated with increased risk of CVD |
| . Change in CD34+ Cell Count | Baseline, Month 6 | Cells expressing CD34 antigen (a protein encoded by the CD34 gene) are called CD34+ cells and can be isolated from blood samples. CD34+ cell count is a biomarker of regenerative capacity and reduced counts of CD34+ is associated with increased cardiovascular risk. |
| Change in Pulse Wave Velocity (PWV) | Baseline, Month 6 | Carotid-femoral artery pulse wave velocity (PWV) will be determined using transcutaneous Doppler flow velocity recordings simultaneously over the common carotid artery and the femoral artery. Aortic pulse wave velocity (PWV) estimates of the speed of the pressure wave traveling along the aorta and is regarded as a direct measure of large artery stiffness. Normal ranges for PWV are age based (PWV increases with age) and standardized thresholds for CVD risk have not been established. This study will assess the change in PWV in participants between baseline and after the 6 month intervention |
| Change in Reactive Hyperemia Index (RHI) | Baseline, Month 6 | Reactive Hyperemia Index (RHI) is a measure of microvascular endothelial function that is calculated as a ratio of preocclusion to postocclusion pulse signal amplitude. RHI will be estimated using digital pulse amplitude tonometry (EndoPAT). Greater RHI indicates better endothelial function. |
| Change in Glutathione | Baseline, Month 6 | Glutathione is a major antioxidant that helps eliminate peroxides and maintain cellular redox. Lower levels of glutathione are associated with cardiovascular disease. |
| Change in circulating progenitor cells (CPC) CD34+/CD133+ | Baseline, Month 6 | Progenitor cells (PCs), including CD34+/CD133+ cells, are part of the mechanisms underlying regeneration, and the pivotal role they play in vascular repair has only recently been appreciated. Endogenous PCs contribute to reendothelialization of tissues after endothelial injury, attenuating progression to frank atherosclerosis. Endothelial dysfunction correlates with PC number and function and a low PC count appears to be an independent predictor of poor outcome in patients with CAD, stroke or acute lung injury. CD34+/CD133+ cell counts improved risk prediction metrics beyond standard risk factors. |
| Change in circulating progenitor cells (CPCs) CD34+/VEGF2R+ | Baseline, Month 6 | Progenitor cells (PCs), including CD34+/VEGF2R+ cells, are part of the mechanisms underlying regeneration, and the pivotal role they play in vascular repair has only recently been appreciated. Endogenous PCs contribute to reendothelialization of tissues after endothelial injury, attenuating progression to frank atherosclerosis. Endothelial dysfunction correlates with PC number and function and a low PC count appears to be an independent predictor of poor outcome in patients with CAD, stroke or acute lung injury. |
| Change in Augmentation Index | Baseline, Month 6 | Augmentation index (AIx) is a composite measure of the magnitude of arterial wave reflections and systemic arterial stiffness and increases as the aortic pulse wave velocity (PWV) increases. Impaired arterial elastic properties, measured as the aortic AIx and/or PWV, are increasingly recognized as independent predictors of incident CVD events (myocardial infarction, stroke, revascularization), as well as all-cause mortality. |
| Change in Carotid Intima Media Thickness (CIMT) | Baseline, Month 6 | A CIMT scan is performed by using ultrasound determine the presence and severity of vascular disease. Presence of carotid plaque is associated with a 2-3-fold increased risk of future CVD events, and increased CIMT is associated with prevalent cardiovascular disease and an increased risk of myocardial infarction and stroke. Progression of CIMT has been used as a surrogate marker of change in CVD risk. |
