RiSE to Prevent Cardiovascular Disease in African Americans

22 octobre 2019 mis à jour par: Karen Saban, Loyola University

The purpose of this pilot study is to evaluate an innovative 8-wk stress reduction program called Resilience, Stress and Ethnicity (RiSE) program designed to reduce chronic stress associated with perceived discrimination among African Americans. African Americans residing in the Maywood community between the ages of 25 and 75 with at least one cardiovascular disease risk factor such as being overweight, having high blood pressure, or diabetes will be enrolled. The following specific aims will be addressed:

Aim 1: Determine the feasibility and acceptability of the program as a strategy to reduce chronic stress in African Americans within the Maywood and surrounding community.

Aim 2: Examine the extent to which training in RiSE (1) improves psychological well being, (2) decreases inflammatory burden, and (3) reduces cardiovascular risk in African Americans

Participants will be randomized to either the RiSE program or the control (no intervention group). Participants will provide blood and saliva samples as well as complete written questionnaires asking them questions about their health, well-being, and early life at the start of the study, half way through the study (at 4 weeks), at the completion of the intervention (8 weeks) and 3 months after the completion of the intervention).

Aperçu de l'étude

Description détaillée

The purpose of this study is to examine an 8-week stress reduction program for African Americans. The aim of this study is to determine the effectiveness of this stress reduction program in improving well-being and reducing risk for heart disease and stroke in African Americans.

No drugs are involved with this study. Participants will be randomized (randomly selected) to either participate in an 8 -week stress reduction program or a control group (no stress reduction program). The stress reduction program entails attending a 2- hour small group class once a week for 8 consecutive weeks at Loyola University in Maywood. Classes will be offered in the evening and will focus on teaching effective strategies for coping with daily stress, particularly stress associated with being an African American.

Blood and saliva samples will be collected at the beginning of the study, in the middle of the program (4 weeks), at the end of the program (8 weeks) and 3 months after the program ends. Blood samples will be analyzed for cholesterol levels, hemoglobin A1c (a measure that reflects blood sugar over time), and cytokines (which reflect inflammation in the body). Saliva samples will be assessed for a hormone called cortisol..

Participants will also complete several written questionnaires to gather information about their stress, social status, perceive discrimination, mood, diet and exercise. Participants will be paid $25 for each of the three data collection time points ($75 total). Those participants who are randomized to attend the stress reduction classes will also be provided $15 for each class that they attend (8 X $15 = $120) to help cover travel expenses.

Que mesure l'étude ?

Principaux critères de jugement

Mesure des résultats
Description de la mesure
Délai
Feasibility of RiSE intervention: questionnaire
Délai: 8 weeks
Feasibility of the RiSE intervention will be assessed at the end of the 8 week program. A written questionnaire will be completed by participants and asking participants to rate their level of satisfaction with the program on a scale of 0 to 10 with 0 being not satisfied at all to 10 being most satisfied. In addition, we will track class attendance and attrition rate.
8 weeks
Coping
Délai: 8 weeks

Participants will complete written questionnaires at baseline, 4 weeks, and 8 weeks:

Adaptive Coping. The Ways of Coping Checklist- Revised (WCCL-R) will be used to measure adaptive and non-adaptive coping. This is a 4-point Likert scale (0 to 3 ) that required the respondent to focus on a current stressor and to choose frequency of each of 66 proposed coping strategies. The WCCL-R is comprised of 5 subscales (scores are summed for each subscale) with higher scores indicating higher levels of the attribute measured by the subscale:

Confrontational coping (scores range from 0 to 18) Distancing (scores range from 0 to 18) Self-controlling (scores range from 0 to 21) Seeking social support (scores range from 0 to 18) Accepting responsibility (scores range from 0 to 12) Escape-avoidance (scores range from 0 to 24) Planful problem-solving (scores range from 0 to 15) Positive reappraisal (scores range from 0 to 21)

8 weeks
Coping with Discrimination
Délai: 8 weeks
Coping with Discrimination. The Coping with Discrimination Scale (CDS) is a 25-item scale that assesses coping strategies with discrimination. Items are answered using a 6-point Likert scale format ranging from strongly agree to strongly disagree. Scores are calculated for 5 subscales: Education/advocacy, Internalization, Drug/alcohol use, Resistance, and Detachment. Mean scores for each subscale range from 1 to 6 with higher scores indicating higher presence of the attribute measured.
8 weeks
Resilience
Délai: 8 weeks
Resilience. The Connor-Davidson Resilience Scale- 25 will be used to measure resilience. The Connor Davidson Resilience Scale-25 is a 25 item questionnaire that examines the extent to which statements representing resilience, such as " I am able to adapt when changes occur" are true for the subject. Each item is evaluated on a five point Likert scale ranging from 0-4: not true at all (0), rarely true (1), sometimes true (2), often true (3), and true nearly all of the time (4). Scores for items are summed and result in total score between 0-100 with higher scores indicating higher resilience.

Délai
Inflammatory burden
Délai: 8 weeks

Inflammatory burden will be measured at baseline and 8 weeks.

Cytokine. ELISA will be used to measure circulating interleukin-6 (IL-6) (R & D Systems, Minneapolis MN). Sensitivity is < 0.7 pg/ml for IL-6. Intra assay variability is <7 %. Circulating IL-6 will be collected at baseline and 8 wks in both the intervention and control groups. Labs will be centrifuged for 7 minutes and frozen at -80 C for later batch analysis.
